Detailed Description

Referring to fig. 1, fig. 1 shows a first structural schematic diagram of an adjustable type glass fiber reinforced plastic demolding device provided by an embodiment of the application. As shown in fig. 1, the adjustable glass fiber reinforced plastic demolding device provided by the embodiment of the application comprises a machine base main body 01, an ejector 02 and a pushing device 03. The machine base main body 01 is a main body part of an adjustable glass fiber reinforced plastic demolding device and is used for arranging the ejection part 02 and the pushing device 03. In order to provide the ejector 02 and the pushing device 03, the housing main body 01 in the embodiment of the present application is a casing structure. Preferably, the housing body 01 is arranged away from the lateral opening of the ejection element 02, in order to provide a structure of the pushing device 03. The ejector 02 is disposed on an outer sidewall of the housing body 01, and is used to eject the glass fiber reinforced plastic from the mold. The pushing device 03 is a component for pushing the ejector 02 to move. The following describes the adjustable glass fiber reinforced plastic demolding device provided by the embodiments of the present application in detail with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 shows a front view of fig. 1. As shown in fig. 2, the ejector 02 includes a fixing base 1 fixedly disposed on the base body 01, and a spring 2 is disposed inside the fixing base 1. In order to facilitate the arrangement of the spring 2 in the fixing seat 1, the fixing seat 1 is of an annular structure. In addition, in order to fix the spring 2 to the fixing base 1, the end of the spring 2 is welded inside the fixing base 1. Along the elasticity direction of spring 2, the inside of spring 2 is equipped with ejector pin 3, and is equipped with spacer 20 on the ejector pin 3. The two ends of the spacer 20 are respectively provided with a spring 2. From this, be equipped with two springs 2 on the knock-out lever 3, and two springs 2 all fix the inside at fixing base 1. In order to realize that the ejector rod 3 pushes the glass steel mold, the ejector rod 3 penetrates through the fixed seat 1, and the ejector rod 3 is located on the pushing device 03. A mold embedded part 21 is arranged above the ejection rod 3 to prevent the ejection rod 3 from damaging the finished glass fiber reinforced plastic product in the process of pushing the glass fiber reinforced plastic upwards.

When the pushing device 03 moves upward, the pushing device 03 can drive the ejecting rod 3 to move upward because the ejecting rod 3 is located on the pushing device 03. Because be equipped with two springs 2 on the knock-out pin 3, and two springs 2 all fix in the inside of fixing base 1, therefore when knock-out pin 3 upwards moved about, the spring 2 that is located the 3 tops of knock-out pin compresses, and at this moment, knock-out pin 3 promotes the activity of plastic injection mould. When the ejector rod 3 moves upwards to a certain degree, the compression force received by the spring 2 above the ejector rod 3 is the largest, and a downward acting force is generated for the spacer block 20, so that the spring 2 below the ejector rod 3 is compressed, and the ejector rod 3 moves downwards. When the compression force applied to the spring 2 located below the knock-out lever 3 reaches a maximum, an upward acting force is applied to the spacer 20, and at this time, the spring 2 located above the knock-out lever 3 is compressed and the knock-out lever 3 moves upward. So, under the effect of two springs 2, ejector pin 3 up-and-down direction reciprocating motion constantly promotes the activity of glass steel mould from this, finally realizes the drawing of patterns of glass steel.

Further, because two springs 2 are all fixed and set up inside the fixing base 1 of annular structure, therefore some springs 2 expose outside through the side of fixing base 1. The spring 2 continuously bounces when the ejector rod 3 pushes the glass fiber reinforced plastic to demould. If an unknown object enters between the springs 2, the springs 2 are easily damaged, and therefore, in the embodiment of the present application, a safety cover 22 is disposed on a side surface of the fixed seat 1 facing away from the base main body 01. The safety cover 22 can protect the spring 2 and workers, and safe production is achieved.

In the embodiment of the present application, two pushing devices 03 are provided, and the following is a detailed description of the pushing devices 03 with reference to the drawings.

As shown in fig. 1 and 2, a first pushing device 03 provided in the embodiment of the present application includes a chuck 4 and a pry bar 5 disposed on one side of a base main body 01. Wherein, the clamping table 4 and the ejection piece 02 are oppositely arranged at two sides of the machine base main body 01. The upper surface of the clamping table 4 is provided with a serrated clamping groove 6, and a clamping piece 7 is movably arranged on the clamping groove 6.

A pry bar guide hole 8 is formed in the base main body 01, and the pry bar guide hole 8 is located below the fixed seat 1. Thus, the pry guide hole 8 corresponds to the open side of the base main body 01. A pry bar 5 is arranged between the clamping piece 7 and the ejecting piece 02, and the pry bar 5 penetrates through a pry bar guide hole 8. Further, one end of the pry bar 5 is located above the card member 7, and the other end is located below the ejector 02, i.e., below the ejector bar 3. Thus, a lever structure is formed among the pry bar 5, the card 7, and the ejector bar 3.

When the one end of pinch bar 5 is pressed downwards, under the supporting action of fastener 7, the other end rebound of pinch bar 5, and then the promotion is located the liftout 3 rebound of pinch bar 5 top, realizes thrust unit 03 to the pushing action of liftout 02. The card slots 6 are continuous because the card slots 6 arranged on the card table 4 are zigzag. And because the clamping piece 7 is movably arranged on the clamping groove 6, the clamping piece 7 has a plurality of placing positions. Thus, the distance between the clip 7 and the base body 01 is different, and further, the distance between the clip and the ejector rod 3 is different. Based on this, different lever distances exist among the pry bar 5, the clamping piece 7 and the ejector rod 3, the generated lever acting force is different, and then the pushing force at the top of the ejector rod 3 is different. The pushing force exerted on the glass fiber reinforced plastics with different volumes during demoulding is different, so that the position of the clamping piece 7 movably placed on the clamping groove 6 can be determined according to the different volumes of the glass fiber reinforced plastics. Therefore, the pushing device 03 provided by the embodiment of the application can be suitable for demolding glass fiber reinforced plastics with different volumes.

Further, in order to prevent the prying bar 5 from popping out from the clamping piece 7 in the prying process, the clamping table 4 in the embodiment of the application is further provided with a first U-shaped limiting piece 9. When the first U-shaped limiting member 9 is disposed on the clamping table 4, the clamping groove 6 is located between the first U-shaped limiting member 9 and the machine base main body 01. The open end of the first U-shaped limiting part 9 is disposed downward, that is, both sides of the first U-shaped limiting part 9 are welded on the clamping table 4, so as to fix the clamping table 4 and the first U-shaped limiting part 9. Under the prerequisite that sets up first U type locating part 9, for realizing that crow bar 5 prizes knock-out lever 3 and prevent that crow bar 5 from popping out from fastener 7 at the in-process of prizing, crow bar 5 is located between first U type locating part 9 and fastener 7.

Furthermore, in order to prevent the prying bar 5 from sliding off the ejection bar 3 during the prying process, a second U-shaped limiting member 10 is disposed on the base main body 01 in the embodiment of the present application. When the base main body 01 is provided with the second U-shaped limiting member 10, the second U-shaped limiting member 10 and the clamping table 4 are oppositely arranged on two sides of the base main body 01. The open end of the second U-shaped limiting member 10 faces the base body 01, and the ejector 02 is located inside the second U-shaped limiting member 10, i.e. the ejector rod 3 is located inside the second U-shaped limiting member 10. Thus, the end of the pry bar 5 does not slip out through the lower side of the knock-out lever 3 by the blocking action of the second U-shaped stopper 10.

Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram illustrating a first structure of an adjustable type glass fiber reinforced plastic demolding device provided in an embodiment of the present application, and fig. 4 is a front view of fig. 3. As shown in fig. 3 and 4, the second pushing device 03 provided in the embodiment of the present application includes a base 11, a sleeve 12, and a torsion bar 13. The base 11 is a T-shaped base, the horizontal part of the T-shaped base is movably arranged on the base main body 01 through screws and the like, the vertical part of the T-shaped base is of a cylindrical structure, and internal threads are arranged in the vertical part of the T-shaped base.

The torsion bar 13 can be inserted into the through hole 14, and the torsion bar 13 is perpendicular to the knock-out bar 3. The top of the sleeve 12 is open and the ejector rod 3 is located inside the opening.

When the glass fiber reinforced plastic needs to be demoulded, the ejector rod 3 can be pushed to move upwards by rotating the torsion bar 13. Specifically, since the base 11 is fixed on the base main body 01, when the torsion bar 13 is rotated, the sleeve 12 rotates on the base 11 along with the torsion bar 13, and further drives the ejector rod 3 to move upwards, thereby realizing the pushing action of the pushing device 03 on the ejector member 02.

Further, in order to prevent the torsion bar 13 from rotating, the base main body 01 also rotates, and the base main body 01 needs to be fixed, so that the base 11 is fixed. In the embodiment of the present application, the rotary supporting members 15 are respectively disposed on two opposite sides of the base main body 01, and the rotary supporting members 15 and the ejection members 02 are respectively disposed on adjacent sides of the base main body 01, so as to form a wing structure of the base main body 01. The rotary supporting member 15 is disposed at the bottom end of the stand body 01, and the opposite side of the rotary supporting member 15, which is not in contact with the stand body 01, is in contact with the ground, so as to increase the friction between the stand body 01 and the ground, thereby achieving the purpose of stabilizing the stand body 01. In addition, the rotation support 15 is provided with a rotation rib 16 to assist the rotation support 15.
