Abstract

The invention belongs to the field of a mold structure and especially relates to an injection mold for manufacturing a cantilever structure product. When the mold is assembled, a front inner mold and a rear inner mold are encircled and formed into an injection chamber for forming a main body of the cantilever structure product; and the rear inner mold and a rear mold sliding block are encircled and formed into an injection chamber for forming a reverse buckling cantilever. After injection molding, an injection molding machine is used for opening the mold, the rear mold sliding block slides and separates from the reverse buckling cantilever, the tail end of the reverse buckling cantilever is outward turned by a drawing mechanism, the reverse buckling cantilever is plastically deformed, and the rear mold sliding block is separated from the rear inner mold; the product packaging force is small, and a simplified jacking mechanism is adopted for pushing the main body away from the rear inner mold, so that the mold stripping is realized; and the rear mold sliding block is reset and the mold is assembled, so as to prepare for the next injection molding. The injection mold is suitable for manufacturing a large-scale cantilever structure product which can be separated from the mold without fully separating the product reverse buckle, and the separating structure configured for the reverse buckling cantilever of the present mold is not required, so that the mold structure is simplified, the rear mold has the space for arranging a more reasonable water channel, the injection molding period is reduced, the mold quality is high, and the production cost is low.

Description

technical field [0001] The invention belongs to the field of mold structure, in particular to an injection mold used for manufacturing cantilever structure products. Background technique [0002] In the existing injection molds, most of the injection molded parts are completely removed from the undercut of the injection molded parts through the pull-out structures such as sliders and inclined tops, so that the injection molded parts can be released from the mold. The cantilever structure product includes a main body and a cantilever on the main body. The cantilever has an assembly function feature, so that the cantilever forms an undercut. If the injection mold for the above-mentioned cantilever structure product adopts strong release, the mechanical analysis of the core release shows that the tightness of the inner mold behind the product is too large, and the product may be pulled directly when it is ejected. This solution is not advisable. If the undercut of the product ...
