Abstract

The invention discloses a forced cooling injection mold device, which comprises a front baffle (5), a plurality of mold cavity boards (6) with cavities formed in inner sides, and a back baffle (7), wherein the plurality of mold cavity boards (6) are positioned between the front baffle (5) and the back baffle (7), a plurality of flow passages of which the upper parts and the lower parts are communicated are arranged in the front baffle (5), the mold cavity boards (6), and the back baffle (7) respectively; a injection molding hole (2) is formed in the front baffle (5); an exhaust hole is formed in the back baffle (7). The cavity parts of mold cavities are formed by the combination of a plurality of parts, so that the mold is allowed to be able to adapt to mold opening of the mold cavities with complex shapes, the enhance of the injection molding precision of plastic products with complex shapes is facilitated, and subsequent reprocessing is eliminated or reduced; the arranged flow passages facilitate the selection of an optimum cooling manner according to a specific material property for better adapting to requirements of cooling speed required to be maintained of the plastic injection molding of different plastics, and therefore, the improvement of the production efficiency of enterprises and the quality of products are facilitated.

Description

technical field

[0001] The invention relates to the field of injection molding equipment, in particular to a forced cooling injection mold device. Background technique

[0002] Injection molding is a processing method used in the mass production of certain parts with complex shapes. Specifically, it refers to injecting heated and melted materials into a mold cavity under high pressure, and after cooling and solidifying, molded products are obtained. Injection mold is a tool for producing plastic products, which gives plastic products complete structure and precise dimensions.

[0003] Existing injection mold is made up of two parts of movable mold and fixed mold, and movable mold and fixed mold are closed to form gating system and mold cavity during injection molding, and movable mold and fixed mold are separated so that take out plastic product when mold is opened. However, due to the ever-changing shapes and structures of plastic products, plastic products with complex sh...
