Referring to fig. 1 and 2, an embodiment of the present invention provides a mold positioning apparatus, which includes a frame 4, a mold hooking mechanism 1, and a limiting mechanism 2.

The mold hooking mechanism 1 includes a first limiting component 11 disposed on the frame 4, the first limiting component 11 is used for connecting or separating with the mold table 3, and is configured to be controllably moved along a first direction relative to the frame 4. The limiting mechanism 2 comprises a second limiting component 21 arranged on the frame 4.

The first limiting component 11 includes a first position and a second position in the process of moving along the first direction. When the first limiting assembly 11 moves to the first position, the first limiting assembly 11 can be connected with the die table 3; when the first limiting component 11 moves to the second position, the first limiting component 11 can drive the die table to move to stop the die table with the second limiting component 21, and the die table 3 is positioned between the first limiting component 11 and the second limiting component 21.

When the die table positioning device is actually operated, firstly, the first limiting component 11 moves to the first position and is connected with the die table 3, so that the die table 3 can move along the first direction along with the first limiting component 11. Then, first spacing subassembly 11 moves to the second position along first direction, and the spacing subassembly 21 of second supports with mould platform 3 and leans on and blocks mould platform 3 and continue to move this moment, and mould platform 3 is injectd between first spacing subassembly 11 and the spacing subassembly 21 of second for mould platform 3 is pinpointed, makes things convenient for follow-up other work such as manipulator marking off, installing clear mould and putting the muscle pre-buried on mould platform 3. Finally, when the die table 3 is not required to be positioned, the first limiting component 11 is separated from the die table 3, so that the limiting of the die table 3 is released. In the embodiment shown in fig. 2, the first direction is a left-right direction.

It should be noted that the first limiting component 11 and the die table 3 can be connected and separated by clamping, adsorbing, hooking, and the like, and the second limiting component 21 can limit the die table 3 by using a common limiting device such as a limiting block and a limiting stopper, which is not limited herein.

It should be further noted that the mold table 3 is moved to a position between the first limiting component 11 and the second limiting component 21 by the mold hooking mechanism 1, and the mold table 3 is positioned by the first limiting component 11 and the second limiting component 21. That is to say, the traditional method of indirectly controlling and positioning the die table 3 by the electric element is replaced by the mechanical positioning structure, so that the interference of external factors is avoided, the repeated positioning precision is higher, and the automatic control of production in a factory is facilitated.

Referring to fig. 1, in some embodiments, the mold hooking mechanism 1 further includes a movable base 10 disposed on the frame 4, and the movable base 10 is configured to be controllably movable in a first direction relative to the frame 4. The first limiting component 11 includes a first hook 111, and the first hook 111 is rotatably disposed on the movable base 10 around a first rotation axis. The process of rotating the first hook 111 around the first rotation axis includes a first state and a second state. When the first hook 111 is in the first state, the first hook 111 can hook the die table 3, so that the die table 3 can move towards a direction close to the second limiting assembly 21 along with the first hook 111; when the first hook 111 is in the second state, the first hook 111 is separated from the die table 3, so that the limit of the die table 3 is released.

In the embodiment, the first hook 111 is provided with an abutting surface. When the first hook 111 is in the first state, the abutting surface abuts against the inner side surface of the die table 3 away from the second limiting component 21, so that the die table 3 is driven to move towards the second limiting component 21 in the process that the first hook 111 moves along the moving seat 10 along the first direction. It can be known that the first hook 111 can be in any shape as long as it can abut against the inner side wall of the die table 3 and drive the die table 3 to move towards the second limiting component 21, which is not limited herein. The first state of the first hook 111 can be any state that the first hook 111 contacts with the inner side wall of the die table 3, as long as the die table 3 can be driven to move towards the second limiting component 21; the second state of the first hook 111 may be any state in which the first hook 111 and the die table 3 are separated from each other, and is not limited herein.

In the embodiment, the first position-limiting assembly 11 further includes a first driving member 112 mounted on the movable base 10 and a first rotating shaft 113 in driving connection with the driving member 112, and the first hook 111 is disposed on the first rotating shaft 113. In the actual use process, the first driving member 112 drives the first rotating shaft 113 to rotate along the circumferential direction and drives the first hook 111 to rotate around the axis of the first rotating shaft 113, so that the first hook 111 hooks the die table 3 and separates from the die table 3. Alternatively, the first driving member 112 may be a tubular electric motor, a reduction motor, a hydraulic motor, etc., and is not limited thereto.

It should be noted that, when the moving seat 10 moves along the first direction, the first hook 111 drives the mold table 3 to move along the first direction along with the moving seat 10, and at this time, the axial force required for driving the mold table 3 to move is concentrated on the output rod of the first driving member 112 or the bearing for fixing the first rotating shaft 113, which is easy to damage the first driving member 112 or the bearing. And because of the existence of the axial force, the output rod of the first driving member 112 or the first rotating shaft 113 is easy to generate axial movement, which finally results in inaccurate positioning of the die table 3, thereby affecting the subsequent processes. To solve this problem, in some embodiments, at least two first bosses 114 are axially spaced on the first rotating shaft 113, and the first position-limiting assembly 11 further includes a first pressing plate 115 mounted on the movable base 10. The first rotating shaft 113 is disposed through the first pressing plate 115, and the first pressing plate 115 is clamped between the two first bosses 114. In this way, by disposing the first pressing plate 115 between the two first bosses 114, the axial force required for driving the mold stage 3 to move is transmitted to the first pressing plate 115 through the two first bosses 114, and the first pressing plate 115 bears a part of the axial force, thereby preventing the first driving member 112 or the bearing from being damaged and preventing the mold stage 3 from being positioned inaccurately due to the axial force.

Alternatively, the first pressing plate 115 is plural, the first rotating shaft 113 is fixed on the movable base 10 by the plural first pressing plates 115, and each first pressing plate 115 is located between two corresponding first bosses 114.

In some embodiments, the second limiting component 21 includes a second hook 211, the second hook 211 is rotatably disposed on the fixing base 20 around a second rotation axis, and the process of rotating the second hook 211 around the second rotation axis includes a third state and a fourth state. Wherein, fixing base 20 sets up in frame 4 for raise second spacing subassembly 21 and make it be in same horizontal plane with first spacing subassembly 11, be convenient for follow-up to the mould platform 3 fix a position. When the second hook 211 is in the third state, the second hook 211 extends out to a moving path of the mold table 3 along with the first limiting component 11 moving along the first direction, so as to stop the mold table 3 when the first limiting component 11 moves to the second position; when the second hook 211 is in the fourth state, the second hook 211 exits from the moving path of the mold table 3 along the first direction with the first limiting component 11. So, when colluding mould mechanism 1 and taking mould platform 3 to the second eave tile 211 department that is in the third state, second eave tile 211 offsets with the lateral wall of mould platform 3, and second eave tile 211 cooperates the first eave tile 111 of colluding mould mechanism 1 to carry on spacingly to mould platform 3 jointly. When the positioning of the mold table 3 needs to be released, the second hook 211 rotates to the fourth state, and is separated from the mold table 3, so that the mold table 3 can continue to move. It should be noted that the second hook 211 may have any shape as long as it can abut against the outer sidewall of the die table 3 and prevent the die table 3 from moving, and is not limited herein. The third state of the second hook 211 may be any state in which the second hook 211 abuts against the outer sidewall of the die table 3, as long as the movement of the die table 3 is prevented; the fourth state of the second hook 211 may be any state in which the second hook 211 and the die table 3 are separated from each other, and is not limited herein.

In the embodiment, the second limiting assembly 21 further includes a second driving member 212 and a second rotating shaft 213 mounted on the frame 4. The second driving member 212 is drivingly connected to the second rotating shaft 213, and the second hook 211 is disposed on the second rotating shaft 213. In the actual use process, the second driving element 212 drives the second rotating shaft 213 to rotate along the circumferential direction and drives the second hook 211 to rotate around the axis of the second rotating shaft 213, so that the second hook can be abutted against and separated from the die table 3. Alternatively, the second driving member 212 may be a tubular electric motor, a reduction motor, a hydraulic motor, etc., and is not limited thereto.

It should be noted that, when the mold table 3 is positioned by the first hook 111 and the second hook 211, the second hook 211 needs to block the outer sidewall of the mold table 3 in the first direction, so as to prevent the mold table 3 from moving further in the first direction. Therefore, the die table 3 presses the second hook 211 along the first direction, and generates an axial force in the first direction to the second hook 211. Meanwhile, the axial force may be concentrated on the output rod of the second driving member 212 or the bearing fixing the second rotation shaft 213, easily causing damage to the second driving member 212 or the bearing. And due to the existence of the axial force, the output rod of the second driving element 212 or the second rotating shaft 213 is easy to generate axial movement, which finally causes inaccurate positioning of the die table 3, thereby affecting subsequent processes.

In order to solve the above problem, in some embodiments, at least two second bosses 214 are disposed on the second rotating shaft 213, and the second limiting member 21 further includes a second pressing plate 215 mounted on the fixing base 20. The second rotating shaft 213 is disposed through the second pressing plate 215, and the second pressing plate 215 is clamped between the two second bosses 214. The axial force generated when the die table 3 is positioned by the second hook 211 is transmitted to the second pressing plate 215 through the two second bosses 213, and a part of the axial force is borne by the second pressing plate 215, so that the damage of the second driving member 212 or the bearing and the inaccurate positioning of the die table 3 caused by the axial force are avoided.

Alternatively, the second pressing plate 215 is plural, the second rotating shaft 213 is fixed on the frame 4 by the plural second pressing plates 215, and each second pressing plate 215 is located between the corresponding two second bosses 214.

In some embodiments, the frame 4 is provided with a sliding groove 41, and the movable seat 10 of the first limiting assembly 11 is movably disposed in the sliding groove 41, so that the sliding groove 41 is used to guide the movement of the movable seat 10. Optionally, a concave sliding groove 41 is formed on one side of the frame 4, and the side of the movable base 10 is installed in the concave sliding groove 41, and the concave sliding groove 41 plays a role of supporting and guiding the movable base 10. In other embodiments, the sliding groove 41 may also be a guide structure such as a groove formed on the frame 4, which is not limited herein.

Optionally, the concave chute 41 is formed by stacking a first chute plate, a second chute plate and a third chute plate on the rack in sequence, and the width of the second chute plate is smaller than the width of the first chute plate and the width of the third chute plate, respectively, so as to form the concave chute 41. Furthermore, the first sliding groove plate, the second sliding groove plate and the third sliding groove plate are fixed on the frame 4 through bolts, and when the concave sliding groove 41 needs to be replaced or maintained, the bolt fixing mode is more convenient.

Further, the mold hooking mechanism 1 further comprises a power source 10 mounted on the frame, and the power source is in driving connection with the movable base 10 and is used for driving the movable base 10 to move along the sliding groove 41. Alternatively, the power source 12 is a structure having a telescopic motion function, such as a hydraulic cylinder push rod, a cylinder push rod, and the like, and is not limited herein.

The embodiment of the invention also provides a die table positioning method using the die table positioning device, and with reference to fig. 3 and 4, the method comprises the following steps:

step S10: the mould table 3 stops moving;

in some embodiments, step S10 specifically includes the following steps:

step S101: the mould table 3 moves under the driving of a driving motor on the concrete prefabricated part production line until an electric limit switch is triggered;

step S102: the electric limit switch controls the driving motor to stop running;

step S103: the die table 3 stops moving after moving for a certain distance under the action of inertia.

It should be noted that the maximum travel of the first limiting assembly 11 must be greater than the first distance between the die table 3 and the designated positioning position when it stops moving under the inertia.

Step S11: the first limiting assembly 11 moves to a first position along a first direction and is connected with the die table 3; the method comprises the following specific steps:

the movable base 10 moves toward the die table 3 along the sliding groove 41 under the driving action of the power source 12 and drives the first limiting component 11 to move, when the first limiting component 11 moves to the maximum stroke, the first driving component 112 drives the first hook 111 to rotate to the first state, and the second driving component 212 drives the second hook 211 to rotate to the third state.
