Abstract

The invention relates to an in-mold gate shearing mechanism applied in a mold. The in-mold gate shearing mechanism includes: a first ejector plate, which is disposed over a lower fixation plate of the mold and is composed of a first upper ejector plate and a first lower ejector plate; a second ejector plate, which is disposed over the first ejector plate and consists of a second upper ejector plate and a second lower ejector plate; a stop block, which is arranged on the first ejector plate and moves together with the first ejector plate when the first ejector plate is ejected, the limiting block and the movement, with clearance disposed between the stop block and the second ejector plate; gate ejector pins, one ends of which are arranged in the first ejector plate and the other ends of which contact the gate; product ejector pins, one ends of which are disposed in the second ejector plate and the other ends of which contact the product. The in-mold gate shearing mechanism provided in the invention needs no shearing action after the product is ejected, thus saving labor and equipment cost. And the shearing part between the product and the gate is beautiful.

Description

【Technical field】 [0001] The invention relates to a mold mechanism, in particular to an in-mold rubber mouth cutting mechanism. 【Background technique】 [0002] In the plastic mold manufacturing industry, there are more and more plastic products for appearance parts. The requirements for this kind of appearance parts are very strict. Manufacturing puts forward higher requirements. [0003] After the product is injection molded in the mold production, there are still glue holes on the product, please refer to figure 1 , which is a schematic diagram of a mold mechanism in the prior art. This existing mold mechanism comprises: upper fixed plate 10, female template 11, male template 12, lower fixed plate 13 and upper ejector plate 20, lower ejector plate 21, product thimble 30, product 40 is taken out after molding is completed, due to glue There is no in-mold cutting mechanism at the mouth 41, the product is ejected together with the glue mouth, and the glue mouth 41 is still...
