Extrusion mould used for producing plastic co-extrusion square tube

Abstract

The invention relates to the technical field of production moulds for plastic products, in particular to an extrusion mould used for producing a plastic co-extrusion square tube, which comprises a mould body, wherein the mould body comprises a mould holder, a transition plate, a support plate, a first converge plate, a second converge plate, a first mouth mould plate, a second mouth mould plate, and a cooling water jacket set; the cooling water jacket set comprises 32 cooling water plates with the same size; a bottom mould sleeve is fixed on the right side of the lower end of the mould holderby welding. According to the extrusion mould used for producing the plastic co-extrusion square tube, temperature regulation blocks with hollow structures are inserted into the cooling water jacket set, and a temperature displayer and temperature conduction blocks for monitoring temperatures at different positions are fixed on an outer side wall of the cooling water jacket set, so that the mould is adjustable in local temperature, local temperature can be displayed directly, and the production efficiency and the production quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic product production molds, in particular to an extrusion mold used for the production of plastic co-extrusion square columns. Background technique [0002] At present, there are many specifications of molds on the market. Among them, the extrusion mold is one of the main molds used to complete the extrusion molding process. Forming. 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 and production efficiency of the product. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is: in order to solve the problems existing in the above-mentioned background technology, an improved extrusion die for the production of plastic co-extrusion squa...
