Abstract

The invention relates to the technical field of mold production, in particular to an extrusion mold with a built-in pressure chamber extrusion device. The extrusion mold comprises a mold body, wherein the mold body comprises an extrusion molding plate, a first manifold, a second manifold, a first supporting plate, a second supporting plate, a transition plate and a bottom arranged extrusion plate. According to the extrusion mold with the built-in pressure chamber extrusion device, air conveying pipelines on the left and right side walls of the bottom arranged extrusion plate respectively supply air to extrusion air sac groups inside pressure chambers in near positions, and then, the expansion speeds of air sacs at different heights are controlled through slow flow air conveying nozzles, so that extrusion sub air sacs can expand from bottom to up to extrude flexible metal extrusion plates, the lateral extrusion force inside a hot melt runner is greatly improved, the internal flow is accelerated, the molding efficiency is improved, the production cycle is shortened, the cost is reduced, and the practicability is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mold production, in particular to an extrusion mold with a built-in pressure chamber extrusion device. Background technique [0002] At present, there are many specifications of molds on the market, and the extrusion mold is one of the main molds used to complete the extrusion molding process. It mainly uses pressure to squeeze the plastic that has been processed by hot melting into the mandrel and the die through the distributor. Between molding. However, in the production process, the design of the traditional extrusion die on the die is unreasonable, and the lateral extrusion force inside the extrusion die cannot be controlled, resulting in low extrusion molding efficiency and seriously affecting the overall quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background techno...
