Detailed Description

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

as shown in figures 1 to 2, the demoulding mechanism suitable for the hard skeleton extruded strip comprises a support I2 connected to a mould template 1, the top surface of the support I2 is connected with a slide rail I4 and a slide rail II 3, a sliding gap is reserved between the slide rail I4 and the slide rail II 3, a sliding key 5 is arranged in the sliding gap, the sliding key 5 moves along the sliding gap, the top surface of one end of the sliding key 5 is connected with a core base I6, a rotating shaft 14 is installed on the core base I6, the core base I6 is rotatably connected with a core base II 7 through the rotating shaft 14, a rotary deflector rod 8 is connected on the core base II 7, the top surface of the core base II 7 is connected with a core 9, the bottom surface of the support I2 is connected with a power device 10 for driving the sliding key 5 to move, the top surface of the support I2 is connected with a rotary slide rail I11 and a rotary slide rail II 12, an overturning gap 13 for the rotary deflector rod 8 to pass through is reserved between the rotary slide rail I11 and the rotary slide rail II 12, the rotary deflector rod 8 slides in the overturning gap 13, and the overturning gap 13 is obliquely arranged, so that the lateral overturning action of the mold core 9 in the process of retreating the sliding key 5, namely the overturning action while retreating is realized. The rotary deflector rod 8 is a cylindrical rod or the rotary deflector rod 8 is a guide wheel which is rotatably connected with the core base II 7.

Slide rail I4 and slide rail II 3 all are equipped with the spout towards one side of sliding key 5, are equipped with on the sliding key 5 with spout assorted slider.

Positioning groove 15 is arranged on the bottom surface of II 7 of the core base, positioning block 16 matched with positioning groove 15 is arranged on I6 of the core base, and positioning groove 15 and positioning block 16 are matched to work, so that the positioning accuracy of II 7 of the core base and I6 of the core base is ensured.

The power device 10 is connected with a support II 17, and the support II 17 is connected with a support I2.

The telescopic end of the power device 10 is connected with a connecting rod 18, the other end of the connecting rod 18 is connected with a sliding connecting rod I19, the upper end of the sliding connecting rod I19 is connected with a sliding connecting rod II 20, and the sliding connecting rod II 20 is connected with one end, far away from the mold template 1, of the sliding key 5.

The power unit 10 is one of an air cylinder, a hydraulic cylinder, and an electric cylinder.

The power device 10 can also be an electric motor, when the power device 10 is the electric motor, a lead screw, a nut and a mounting plate work in a matching way to complete the movement of the sliding key 5, the specific connection is that an output shaft of the electric motor is connected with the lead screw, the nut is connected on the lead screw, the bottom surface of the nut is movably connected with the mounting plate, and the top surface of the nut is connected with the sliding key 5.

Slide rail I4 and slide rail II 3 are connected with 1 top surface of mould template towards the one end bottom surface of mould template 1.

When the core mold turning device works, the power device 10 works to push the sliding key 5 to horizontally retreat from the initial position, the core base I6 horizontally retreats along with the sliding key 5, after the rotating deflector rod 8 enters the turning gap 13 between the rotating slide rail I11 and the rotating slide rail II 12, the core 9 can be laterally turned in the retreating process along with the horizontal retreat of the core base I6, and after the core 9 is turned to a certain angle, the power device 10 reaches the end position and stops moving. The process of returning the power unit 10 from the end position to the start position is the reverse of the above-described process.

The movement of the core 9 is in the form of a first back-off and then a lateral inversion during the back-off. The direction of set back is the direction of the extruded strip. The backing-in is because there are other parts in front, the core 9 must be backed a certain distance to have enough space to turn out from the extruded strip. The purpose of the side turning is to rotate the part out of the small gap of the G-shaped section, and the rotated core 9 cannot be shielded above the extrusion strip, so that the unloading action of an operator is prevented from being influenced.

According to the invention, manual demoulding operation is replaced by mechanical automatic demoulding, so that the production efficiency is improved, the movement of an automatic mechanism is realized, and the positioning precision of parts is good.
