Abstract

The invention discloses a female mold anti-sticking structure applied to double injection molds. The anti-sticking structure comprises a plurality of cylindrical bosses which are uprightly arranged on a male mold core respectively and protruding into a product, wherein the bosses and the male mold core are made from the same material. According to the anti-sticking structure, the contact area of the product and the male mold core is increased by virtue of the bosses on the male mold core, the area of the male mold core on which the product is located is larger than that of a female mold core and consequently the product is prevented from sticking to a female mold; by the female mold anti-sticking structure, the loss is reduced and the efficiency is enhanced, and the anti-sticking structure does not cause any influence on product assembly.

Description

【Technical field】 [0001] The invention relates to a master mold anti-sticking structure, in particular to a master mold anti-sticking structure applied to a two-color mold. 【Background technique】 [0002] The two-color mold includes the first injection master mold, the second injection master mold and two identical male molds. When the core area of ​​the male mold where the product is located is smaller than the core area of ​​the female mold, in order to prevent the product from sticking to the female mold, we now Some technologies usually take the following three measures: [0003] Option 1, scratching, do scratching treatment on the male mold core, increase the contact area between the product and the male core to increase the sticking force, but the cost is expensive; [0004] Option 2, barb treatment, the barb is set on the thimble, but the follow-up processing is troublesome, which will easily cause process delay and reduce work efficiency; [0005] The third option ...
