A rapid prototyping mold for pe pipes

Abstract

The invention discloses a rapid prototyping mold for PE pipes, which comprises a support base plate 1, a plurality of support feet are installed on the bottom end of the support base plate 1, and a first A detachable clamping block is clamped in the first clamping slot, and a first fixing bar is fixedly connected to a side wall of the detachable clamping block. In the present invention, through the provided injection molding bottom mold and injection molding top mold, after the operation of motor 1, the meshing of the first toothed plate and the first ring gear is used, and at the same time, under the cooperation of the lifting device, the injection molding bottom mold can be connected to the injection molding top mold. Separate, and inject coolant into the cooling cavity on the injection top mold, so that the PE resin material can be cooled quickly, thereby accelerating the forming of the pipe, and it is convenient to export the rough pipe after forming. The entire structure design is reasonable and the degree of mechanization High and very easy to operate.

Description

Technical field [0001] The present invention belongs to the field of PE pipe production equipment, relates to a rapid prototyping mold for PE pipe. Background [0002] PE, is polyethylene (Polyethylene of raised temperature resistance of the English abbreviation), the general PE pipe feed water pipeline application range is less than 40 ° C temperature, can not be used for hot water pipeline, PE pipe is a high crystallinity, non-polar thermoplastic resin, the original HDPE appearance is milky white, in the thin section of a certain degree of translucency, PE has excellent resistance to most domestic and industrial chemicals, and some kinds of chemicals produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). [0003] Existing PE pipe in the process of molding processing, need to use a special mold, and the molten state of the resin into the mold groove, the use of specifi...

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
