Extrusion mould used for plastic co-extrusion wall board

Abstract

The invention relates to the technical field of plastic production moulds, in particular to an extrusion mould used for a plastic co-extrusion wall board, which comprises a mould body, wherein the mould body comprises a mould body plate, a transition plate, a support plate, a converge plate, a mouth mould plate, a cooling water jacket and a co-extrusion plate; the mould body plate, the transitionplate and the support plate are internally provided with right mounting through holes; the mouth mould plate, the cooling water jacket and the co-extrusion plate are internally provided with left mounting through holes at centers. According to the extrusion mould used for the plastic co-extrusion wall board, the mounting through holes on the two sides and through water core bars insides the mounting through holes communicate by adopting the converge plate provided with external thread connecting rings on two sides, thus mounting and dismounting of the whole mould are greatly facilitated, the cost is greatly lowered, the internal temperature is controllable, and the production efficiency and the production quality are greatly improved.

Description

technical field [0001] The invention relates to the technical field of plastic production molds, in particular to an extrusion mold for plastic co-extrusion wallboards. 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 traditional extrusion die has a single fixed structure, which is inconvenient to assemble and disassemble, 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 . Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to ...

AI Technical Summary

Problems solved by technology

[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 plastic co-extrusion wallboard is provided, which solves the problem that the traditional extrusion die has a single fixed structure and is difficult to assemble and disassemble. It is convenient, 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.
