Extrusion mould used for producing plastic floor

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 floor, which comprises a mould body, wherein the mould body is provided with an integral-structured transition block on a left side wall of the mould body; the transition block is provided with an integral-structured rear support block on a left side wall of the transition block; the rear support block is provided with an integral-structured front support block on a left side wall of the rear support block; the front support block is providedwith an integral-structured converge block on a left side wall of the front support block. According to the extrusion mould used for producing the plastic floor, holding channels for a metal piston cylinder body are formed in the front support block and the rear support block, a piston is controlled by an adjusting bolt so as to stretch out and draw back inside the metal piston cylinder body and to drive suction of cooling water in a horizontal cooling water runner and detachment of the metal piston cylinder body, a water introducing core bar is matched together to control the temperature in the mould, the mould is adjustable in local temperature, 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 plastic floor production. 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 by the present invention is: in order to solve the problems existing in the ...
