Abstract

Disclosed are a cooling control device and method for an injection mold. The cooling control device comprises a controller, a water inlet pipe, an upper end cooling flow channel, a water outlet pipe and a lower end cooling flow channel, and the water inlet pipe, the upper end cooling flow channel, the water outlet pipe and the lower end cooling flow channel are arranged in the injection mold and are connected sequentially. A water inlet of the upper end cooling flow channel and a water inlet of the lower end cooling flow channel are connected with the water inlet pipe. A water outlet of the upper end cooling flow channel and a water outlet of the lower end cooling flow channel are connected with the water outlet pipe. The controller is connected with the water inlet end of a cooling circuit, the water outlet end of the cooling circuit and the inner surface of the injecting mold. The controller collects and calculates the temperature difference of working media of the upper end cooling flow channel and the lower end cooling flow channel, and the surface temperature difference of the injection mold, and adjusts the flow of a medium in the cooling circuit according to the temperature differences, so that the cooling of the injection mold is achieved. The cooling control device and method for the injection mold are reasonable in design, simple in structure, capable of reducing the rejection rate, and small in buckling deformation of an injection member.

Description

technical field [0001] The invention relates to a technology in the field of injection molds, in particular to a cooling control device and method for injection molds. Background technique [0002] Injection mold is a tool for producing plastic products, and it is also a tool for giving plastic products complete structure and precise dimensions. 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 molds are divided into thermosetting plastic molds and thermoplastic plastic molds according to the molding characteristics; according to the molding process, they are divided into transfer molds, blow molds, casting molds, thermoforming molds, hot compression molds (compression molds), injection molds, etc. Among them, the hot pressing mold can be di...
