Extrusion die for producing four-hole plate

Abstract

The invention relates to the technical field of production equipment, in particular to an extrusion die for producing a four-hole plate. The extrusion die comprises a die body. The left side of the die body is connected with a transition plate. The left side of the transition plate is connected with a rear support plate. The left side of the rear support plate is connected with a front support plate. According to the extrusion die for producing the four-hole plate, a heat conduction barrel with a cooling water flow groove is fixed to the inner wall of an extrusion runner, and therefore the cooling performance of the interior of the extrusion runner is more consistent, and the temperature is more uniform and controllable. A small water passing core bar on the left side of a main core bar is utilized for cooling the whole main core bar and a diversion cone, the sizing efficiency is greatly improved, the work time is shortened, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to an extrusion die for producing four-hole plates. 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, during the production process, there is no cooling device installed on the extrusion die traditionally used to produce four-hole plates, and the internal temperature cannot be controlled, resulting in low extrusion molding efficiency and seriously affecting 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 solve the problems existing in the abo...
