The invention discloses an injection mold. The injection mold comprises an upper runner plate, a lower runner plate and a female mold core which are sequentially arranged in the mold closing direction, the lower runner plate and the female mold core are locked through a locking piece, and the upper runner plate is opened and closed relative to the lower runner plate; a lower runner plate insert is movably arranged in the lower runner plate, a female mold core movable insert is movably arranged in the female mold core, and the lower runner plate insert and the female mold core movable insert are locked through a locking piece; a second elastic piece is arranged in the lower runner plate insert, one end of the second elastic piece abuts against the lower runner plate insert, and the other end abuts against the female mold core, so that a power part of the lower runner plate insert extends out of the end surface of the lower runner plate. An existing female mold anti-sticking mold structure is optimized, a female mold pressing plate can be omitted, the characteristics of preventing a plastic product from sticking to a female mold and automatically ejecting the plastic product can be met at the same time, and the problem that the manufacturing cost of raw materials and the mold is increased due to the fact that a runner is lengthened and the thickness of the female mold plate is increased due to existence of the female mold pressing plate is solved.
Description
technical field [0001] The invention belongs to the technical field of plastic product molding, and particularly relates to an injection mold. Background technique [0002] Most plastic products are made by injection molding of plastic molds, which are usually 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 and development. In the production process of plastic products, for a type of plastic products with large side size of the master mold, small draft angle, large clamping force of the sub-injection, and need to use dispensing glue, after injection molding, during the mold opening process, this Plastic-like products are very easy to stick to the master mold, and even completely stay on the side of the master mold, so that the molded plastic product cannot be removed smoothl...
