Extrusion die with external detachable water-cooling temperature adjustment device

Abstract

The invention relates to the technical field of dies, and particularly relates to an extrusion die with an external detachable water-cooling temperature adjustment device. The extrusion die with the external detachable water-cooling temperature adjustment device comprises a raw material extrusion plate internally provided with a raw material extrusion hole, wherein a support plate internally provided with a raw material extrusion hole is fixedly connected to the lower end of the raw material extrusion plate; and a first transition plate internally provided with a raw material extrusion hole is fixedly connected to the lower end of the support plate. According to the extrusion die with the external detachable water-cooling temperature adjustment device, which is disclosed by the invention, the heat dispersion performance of the die is improved through connecting and fixing auxiliary connection blocks internally provided with four-way water valves at vertex-angle positions of the outer sides of a first confluence plate, a second confluence plate and a forming extrusion plate in a clamping manner, and externally connecting cooling water conveying tubes through connecting water tubes and external water tubes at the outer sides of the four-way water valves; temperature control performance of the auxiliary connection blocks is achieved through installing manual switches on the auxiliary connection blocks, thus the production efficiency and product quality are greatly improved; and the whole cooling device is convenient to install, simple in connection and control manners, long in service life, and low in later maintenance cost.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an extrusion die with an external water-cooling and temperature-regulating device that can be easily disassembled. 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 controlled, resulting in low extrusion molding efficiency and seriously affecting the overall quality of the product. Functional extrusion dies are expensive to produce, have a short lifespan and cannot be disassembled. Contents of the invention [0003] The tec...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to solve the problems in the above-mentioned background technology, provide an improved extrusion die with an external easy-to-detachable water-cooling and temperature-regulating device, and solve the traditional extrusion die design on the die. Unreasonable, the temperature inside the extrusion mold cannot be controlled, resulting in low extrusion molding efficiency and seriously affecting the overall quality of the product. Generally, extrusion molds with temperature adjustment function have high production costs, short lifespan and cannot be disassembled.
