Prevent the soft rubber runner from sticking to the oblique pin mechanism

Abstract

The present invention provides a mechanism for preventing sticking of a soft rubber flow channel with an oblique pin, which includes: an oblique pin and an ejector pin, the lower ends of the oblique pin and the ejector pin are fixed on the second countersunk head and arranged inside the upper ejection plate, and the upper end of the oblique pin It passes through the male template and the male mold core and extends into the product; it also includes: a glue-feeding oblique pin, the upper end of which passes through the male template and the male mold core and extends into the product; The lower end of the pin is connected, and its lower end is fixed to the third countersunk head. The oblique pin rod moves up and down in the upper ejector plate and the lower ejector plate; the first channel thimble, the upper end of which passes through the male template and the male mold core and extends into the product. Among them, its lower end is fixed on the fourth countersunk head, and the runner thimble moves up and down in the upper ejection plate and the lower ejection plate; the first movable pin is fixed at the lower end of the oblique pin rod; the second movable pin is fixed At the lower end of the runner thimble. The mechanism for preventing the sticking of the soft rubber flow channel to the inclined pin can prevent the soft rubber flow channel from sticking to the inclined pin, and finally the product can be taken out safely.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to a diagonal pin mechanism for preventing soft glue flow channels from sticking. 【Background technique】 [0002] At present, due to the different usage methods of the casings of some electronic products, a combination of hard glue and soft glue is designed on the cover shell. see figure 1 , figure 1 A schematic diagram of the structure of a product is shown. The surface of the product 100 is provided with a hard glue 110 , and a soft glue 120 is arranged around the hard glue 110 . After the soft rubber runner 130 is filled with glue, the glue inlet on the soft rubber runner 130 is not easy to be broken, and it is easy to stick to the inclined pin, so that the soft rubber runner 130 is not easy to be taken out. cause damage. [0003] In view of this, it is necessary to design a mechanism for preventing the soft rubber runner from sticking to the oblique pin, so as to solve the problem that...

AI Technical Summary

Problems solved by technology

After the injection of the soft rubber runner 130 is completed, the glue inlet on the soft rubber runner 130 is not easy to break, and it is easy to stick to the oblique pin, making it difficult to take out the soft rubber runner 130. If it is forcibly taken out, it may damage the product. cause damage

[0003] In view of this, it is necessary to design a mechanism to prevent the soft rubber flow channel from sticking to the oblique pin, so as to solve the problem that the rubber inlet on the soft rubber flow channel 130 is pasted on the inclined pin, resulting in the problem that the soft rubber flow channel 130 cannot be quickly taken out.
