Description

Technical Field

[0001] The utility model relates to a plastic injection mold, in particular to a secondary ejection and demoulding mechanism for a small seesaw Background Art

[0002] Plastic injection molds are tools for producing plastic products and are widely used. In the injection molding of plastic products, as Figure 5 shown, since the outer wall 101 of the plastic product 100 is relatively high, it is difficult to take out the part after injection molding. If the length of the ejector pin is simply increased, the height of the mold will be increased, thereby increasing the manufacturing cost of the mold. Therefore, it is necessary to design a mechanism that can eject the molded plastic product 100 to a higher height. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a secondary ejection and demoulding mechanism for a small seesaw that increases the ejection stroke of the ejector pin.

[0004] To achieve the above purpose, the technical solution of the utility model is as follows:

[0005] The utility model is a secondary ejection and demoulding mechanism for a small seesaw, including an ejector pin plate, a seesaw, a pin, an ejector pin, and a push rod;

[0006] The middle of the seesaw has a through hole, one side of the seesaw has a clamping groove, and the other side of the seesaw has a support platform; the seesaw is movably installed in the ejector pin plate, the middle of the pin is fixedly penetrated in the through hole of the seesaw, and both ends of the pin extend out of the seesaw and are installed in the ejector pin plate with a gap, and the seesaw can swing around the pin. The lower end of the ejector pin is clamped in the clamping groove of the seesaw, the upper end of the ejector pin extends into the cavity, and the lower end of the push rod abuts against the support platform of the seesaw.

[0007] The ejector pin plate is composed of an ejector pin panel and an ejector pin bottom plate; the ejector pin panel and the ejector pin bottom plate are fixed together, and a seesaw groove is provided between the ejector pin panel and the ejector pin bottom plate, and the seesaw is movably sleeved in the seesaw groove.

[0008] The lower end of the ejector pin has a disc head, and the disc head is clamped in the clamping groove of the seesaw with a gap.

[0009] After adopting the above scheme, since the utility model includes an ejector pin plate, a seesaw, a pin, an ejector pin, and a push rod, after the mold is opened, the moving template and the fixed template are separated, the ejector pin plate ejects, the ejector pin plate drives the ejector pin to eject the product for the first time. After reaching the limit position of the stroke of the ejector pin plate, the upper end of the push rod abuts against the bottom surface of the moving template, and the push rod pushes one end of the seesaw, so that the other end of the seesaw pushes the ejector pin upward, realizing the secondary ejection of the ejector pin, increasing the ejection stroke of the ejector pin, and thus achieving the effect of secondary ejection.

[0016] As Figure 1 、 Figure 2 shown, the present utility model is a small seesaw secondary ejection and demolding mechanism, including a thimble plate 1, a seesaw 2, a pin 3, a thimble 4, and a push rod 5.

[0017] The middle of the seesaw 2 has a through hole 21, one side of the seesaw 2 has a card slot 22, and the other side of the seesaw 2 has a support platform 23; the seesaw 2 is movably installed in the thimble plate 1, the middle of the pin 3 is fixedly penetrated in the through hole 21 of the seesaw 2, both ends of the pin 3 extend out of the seesaw 2 and are installed in the thimble plate 1 with a gap, the seesaw 2 can swing around the pin 3, the lower end of the thimble 4 is clamped in the card slot 22 of the seesaw 2, the upper end of the thimble 4 extends into the cavity, the lower end of the push rod 5 abuts against the support platform 23 of the seesaw 2, and the upper end of the push rod 5 can abut against the bottom surface of the moving template 10.

[0018] The thimble plate 1 is composed of a thimble face plate 11 and a thimble bottom plate 12; the thimble face plate 11 and the thimble bottom plate 12 are fixed together, and a seesaw groove 13 is provided between the thimble face plate 11 and the thimble bottom plate 12, and the seesaw 2 is movably sleeved in the seesaw groove 13.
