Injection mold with mold cavity cleaning structure

Abstract

The invention discloses an injection mold with a mold cavity cleaning structure, and belongs to the technical field of injection molds. The injection mold comprises a base, wherein the top of the baseis fixedly connected with a lower mold; the bottom of the lower mold penetrates through and extends into the base; an upper mold is arranged above the lower mold; the inner bottom wall of the base isfixedly connected with a first motor; the top of the first motor is fixedly connected with a screw rod through a coupler; and the outer part of the screw rod is in threaded connection with a liftingframe. According to the injection mold, impurities on the inner wall of the lower mold can be scraped off in the ascending process of a scraping plate, a second motor can drive a connecting shaft to rotate, so that a gear fixed outside the second motor can rotate; and the gear is meshed with a convex block, so that the gear can move rightwards, the connecting shaft moves rightwards, cleaning frames can be driven to move rightwards, the tops of the two cleaning frames are fixedly connected with a cleaning assembly, the cleaning assembly can move rightwards to clean the scraping plate, and therefore the cleaning effect is more thorough.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold with a cavity cleaning structure. Background technique [0002] Injection molding, also known as injection molding, is a molding method of injection and molding. Injection molding is suitable for mass production and complex-shaped products and other molding processing fields. At a certain temperature, the completely molten plastic material is stirred by a screw. It is a method of obtaining molded products by injecting high pressure into the mold cavity, cooling and solidifying. [0003] This method is suitable for mass production of parts with complex shapes, and is one of the important processing methods. During the use of the injection mold, a large amount of injection liquid often adheres to the cavity, and it is difficult to clean the cavity adhered to the mold. Contents of the invention [0004] 1. Technical problems to be solved [0005] In vie...
