Abstract

The invention relates to the technical field of plastic extrusion moulds, in particular to an extrusion mould used for producing a plastic square tube, which comprises a mould body, wherein the mouldbody comprises a main mould body, a transition plate arranged on the left side of the main mould body, a rear support plate arranged on the left side of the transition plate, a front support plate arranged on the left side of the rear support plate, a converge plate arranged on the left side of the front support plate, a mouth mould plate arranged on the left side of the converge plate, a first cooling water jacket plate arranged on the left side of the mouth mould plate, and a second cooling water jacket plate arranged on the left side of the first cooling water jacket plate. According to theextrusion mould used for producing the plastic square tube, extrusion runners internally provided with core bars are formed inside, a guide plate for evenly guiding a material in a crowding-in runnerinto the extrusion runners, the production molding efficiency is improved by utilizing annular water holes in the peripheries of the extrusion runners and metal heat conducting rings insides the extrusion runners, and the quality of the integral product is greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic extrusion dies, in particular to an extrusion die used for the production of plastic square pipes. Background technique [0002] At present, there are many specifications of molds on the market, and the extrusion mold is one of the main molds used to complete the extrusion molding process. It mainly uses pressure to squeeze the plastic that has been processed by hot melting into the mandrel and the die through the distributor. Between molding. However, in the production process, the design of the traditional extrusion die on the die is unreasonable, and the temperature inside the extrusion die cannot be locally controlled, resulting in low extrusion molding efficiency, which seriously affects the overall quality of the product and production efficiency. Contents of the invention [0003] The technical problem to be solved in the present invention is: in order to solve the problems existing in t...
