Problems solved by technology

[0002] At present, the undercut of injection molding products is mainly based on the integral slanted top. The slanted top is square, and it is easy to get stuck when ejecting, which affects mass production. Moreover, the integral slanted top is long, difficult to process, and easy to deform and bend. Larger slanted roofs are prone to abnormal noises and even broken slanted roofs

Embodiment Construction

[0013] Such as Figure 1-Figure 3 As shown, the present invention is an undercut insert mechanism for injection molding products, including an undercut insert 1 , a push rod 2 , a positioning pin 3 , a guide block 4 , a slider 5 , and a slider seat 6 .

[0014] The upper end of the undercut insert 1 extends into the cavity, the lower end of the undercut insert 1 is hinged on the top of the ejector rod 2 through the positioning pin 3, and the middle part of the ejector rod 2 is movably inserted in the guide hole 42 of the guide block 4 , the lower end of the push rod 2 is connected with the guide block 4, and the guide block 4 is slidably connected in the slider groove 61 of the slider seat 6.

[0015] The outer wall of the guide block 4 is provided with a positioning block 41, the positioning block 41 is fixed on the movable template 10 by the screw 7, and the positioning block 4 plays the role of preventing the ejector rod 2 from rotating.

[0016] In this embodiment, the gu...

Abstract

The invention discloses an injection molding product back-off insert mechanism. The mechanism comprises a back-off insert, an ejector rod, a positioning pin, a guide block, a sliding block and a sliding block seat, wherein the upper end of the back-off insert extends into a cavity, the lower end of the back-off insert is hinged to the top of the ejector rod through the positioning pin, the middleof the ejector rod is movably arranged into a guide hole of the guide block in a penetrating mode, the lower end of the ejector rod is connected with the guide block, and the guide block is slidably connected in a sliding block groove of the sliding block seat. According to the mechanism, due to the fact that the ejector rod can move up and down in the guide block, the ejector rod is not prone todeformation and bending, the sliding block can slide back and forth in the sliding block seat, the movement is smooth, the action is stable and reliable, product core pulling can be well achieved, ejection for batch production is smooth, the processing technology is simple, and the cost is lower.

Description

technical field [0001] The invention relates to an injection mold, in particular to an undercut insert mechanism for an injection molded product. Background technique [0002] At present, the undercut of injection molding products is mainly based on the integral slanted top. The slanted top is square, and it is easy to get stuck when ejecting, which affects mass production. Moreover, the integral slanted top is long, difficult to process, and easy to deform and bend. A large slanted roof is prone to abnormal noise, and even the slanted roof breaks. Contents of the invention [0003] The purpose of the present invention is to provide a stable and reliable undercut insert mechanism for injection molding products. [0004] For realizing the above object, technical solution of the present invention is: [0005] The invention relates to an undercut insert mechanism for injection molding products, which includes an undercut insert, a push rod, a positioning pin, a guide block,...
