Rapid forming mold for PE pipe

Abstract

The invention discloses a rapid forming mold for a PE pipe. The rapid forming mold comprises a first supporting bottom plate. A plurality of supporting bottom feet are installed at the bottom end of the first supporting bottom plate. A first clamping groove is formed in the side wall of the top end of the first supporting bottom plate. A detachable clamping block is connected into the first clamping groove in a clamped manner. A first fixing strip is fixedly connected to one side wall of the detachable clamping block. According to the rapid forming mold, an injection bottom mold and an injection top mold are arranged to cooperate with operation of a first motor, a first tooth disc and a first tooth ring are utilized for being engaged, meanwhile, under the cooperation of a lifting device, the injection bottom mold can be separated from the injection top mold, a coolant is injected into a cooling cavity in the injection top mold, thus a PE resin material can be cooled rapidly, thus forming of the pipe is accelerated, a formed pipe rough blank can be guided out conveniently, the overall structure is reasonable in design, the mechanical degree is high, and operation is very easy.

Description

technical field [0001] The invention belongs to the field of PE pipe production equipment and relates to a rapid prototyping mold for PE pipes. Background technique [0002] PE is polyethylene (English abbreviation for Polyethylene of raised temperature resistance). Generally, the application range of PE pipe water supply pipes is below 40°C, and cannot be used for hot water pipes. PE pipe is a kind of high crystallinity, non-toxic Polar thermoplastic resin, the appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals, and some types of chemicals will produce chemical Corrosion, such as corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). [0003] In the process of forming the existing PE pipes, special molds need to be used, and the molten resin is passed into the mold groove, an...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a rapid prototyping mold for PE pipes, which solves the problems in the prior art: the existing PE pipes need to use special molds during the molding process, and the molten state The resin is passed into the mold groove, and the PE resin is formed by using the specific mold shape in the mold, and then after a certain period of cooling, the formed PE pipe rough blank is exported from the mold, mainly relying on natural cooling during the period. Some factories use water cooling for cooling, which has low efficiency and long cooling time, and it is also very inconvenient to export the formed PE pipe rough blank
