An injection mold for PE pipe production

Abstract

The invention discloses an injection mold for PE pipe production. A bottom plate, an upper mold base and a lower mold base are included. The lower mold base is welded to the middle portion of the upper end of the bottom plate. An injection molding groove is formed in the middle portion of the upper end of the lower mold base, and an annular clamping groove is formed in one side of the injection molding groove. The injection mold has the beneficial effects that through design of an exhaust fan, an air pipe, an air gathering hood and a purification box, waste gas generated in the injection molding process can be effectively treated, and cleanliness of the injection molding environment is ensured; through the design of an electric push rod, separation of the upper mold base and the lower moldbase is more convenient, separation can be conducted without a bolt detachment manner, and the mold taking efficiency is greatly improved; and through the design of a liquid injection ring pipe and annularly-distributed injection molding pipes, injection molding liquid can evenly fall down along a cavity at the same time in the injection molding process, local accumulation of the injection molding liquid is avoided, and the injection molding quality is improved.

Description

technical field [0001] The invention relates to the technical field of pipe fitting molds, in particular to an injection mold for PE pipe production. Background technique [0002] PE pipe is a pipe fitting made of polyethylene plastic, which has excellent resistance to most domestic and industrial chemicals, and is often used as a substitute for steel pipes and iron pipes in various fields of people's lives. Among them, injection molds are used in the production process of PE pipes. However, the existing injection molds for PE pipe production lack waste gas collection and purification devices, so that the waste gas generated during the injection molding process of PE pipes cannot be treated in time, causing pollution. In the injection molding environment, and limited by the structure of the existing injection mold for PE pipe production during the mold taking process, the mold can only be disassembled by removing the bolts to complete the mold taking operation, and the mold ...

AI Technical Summary

Problems solved by technology

Among them, injection molds are used in the production process of PE pipes. However, the existing injection molds for PE pipe production lack waste gas collection and purification devices, so that the waste gas generated during the injection molding process of PE pipes cannot be treated in time, causing pollution. In the injection molding environment, and limited by the structure of the existing injection mold for PE pipe production during the mold taking process, the mold can only be disassembled by removing the bolts to complete the mold taking operation, and the mold taking efficiency is relatively low. In addition, it lacks the design of the guide parts, so that the local accumulation of injection liquid often occurs during the injection molding process, thereby reducing the quality of injection molding. Therefore, an injection mold for PE pipe production is urgently needed to solve the existing problems.
