The invention discloses a female mold anti-sticking structure applied to a mold. The mold includes a lower fixed plate, an upper ejection plate, a lower ejection plate, a male template, a female template, a male mold core and a female mold core. The female mold anti-sticking structure comprises a circular insert and a sleeve, wherein the circular insert is movably arranged in the female mold core; one end of the circular insert is butted against a convex column of a product; the sleeve is provided with a cylinder and a core; one end of the cylinder is fixed in the upper ejection plate, and the other end of the cylinder is butted against the convex column of the product; and one end of the core is fixed in the lower fixed plate, and the other end of the core extends into the convex column. According to the female mold anti-sticking structure, after the mold is opened, downward thrust is given to the convex column through the movable circular insert, so that the convex column is prevented from bonding on the female mold; and the core of the sleeve extends into the convex column, so that the convex column needs no mold drawing, and subsequent nut embedding is convenient.
Description
【Technical field】 [0001] The invention relates to a mold structure, in particular to a master mold anti-sticking structure. 【Background technique】 [0002] Plastic products are formed by injection molding through plastic molds, and plastic products are often used in electronic products, communication products and consumer products. In recent years, with the widespread use of electronic products, communication products and consumer products, plastic molds have also become the subject of extensive research. [0003] There is often a hollow post (BOSS post) in the plastic product, and the function of the post is to build a nut after the plastic product is formed. If the shape of the convex column is all in the female mold part of the mould, it is easy to stick to the female mold. [0004] see figure 1 as shown, figure 1 Shown is a master mold release structure of the prior art. The anti-sticking structure of the master mold in the prior art includes a round insert 10 , one...
