Problems solved by technology

[0004] In view of the above-mentioned complex plastic products, it is often inconvenient to open the movable mold and the fixed mold. The injection molding cannot be completed in one step, and the injection precision can only be reduced. The shape requirements are achieved through post-processing, which is not conducive to the production efficiency of the enterprise. In order to solve the problem of poor controllability of mold heat preservation and forced cooling heat transfer speed, the invention provides an injection mold device with a heating device

Abstract

The invention discloses an injection mold device with a heating device. The injection mold device comprises a front baffle plate (5), a plurality of cavity plates (6) provided with cavities formed in the inner sides, a rear baffle plate (7) and an electric heater (8), wherein the front baffle plate (5), the cavity plates (6) and the rear baffle plate (7) are provided with a plurality of flow passages of which the upper parts and the lower parts are communicated; the front baffle plate (5) is further provided with an injection molding hole (2); the rear baffle plate (7) is further provided with an exhaust hole. The injection mold device can adapt to mold opening of cavities in complex shapes, is conducive to improving injection molding precision of plastic products with complex shapes, and can eliminate and reduce follow-up reprocessing; with the flow passages and the electric heater, the injection mold device can well adapt to cooling speeds required to be kept in different plastic injection molding processes and requirements of mold temperature during injection molding, and is conducive to improving production efficiency of enterprises and product quality.

Description

technical field [0001] The invention relates to the field of injection molding equipment, in particular to an injection mold device with a heating 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 co...
