Abstract

The invention is suitable for the technical field of dies and provides a sheet die head. The die heat is applied to extrusion forming to obtain plastic sheets and has a co-extrusion characteristic, namely two extruders extrude materials to form a sheet which has three layers. The plastic extruded by one extruder is used as a middle layer, and the plastic extruded by the other extruder is divided into an upper layer and a lower layer. The sheet is extruded by the two extruders, so that two different raw materials can be synthesized to form the sheet; the upper layer and the lower layer are required to be surface layers of a product; the middle layer of the plastic sheet can be a regenerated plastic resource for filling, so that the cost of the product is reduced; the sheet die head has a technical characteristic and a market competition advantage.

Description

technical field [0001] The invention belongs to the technical field of sheet molds, and particularly relates to a sheet mold head. Background technique [0002] The application of plastic sheets in the national economy is increasingly widespread, which greatly promotes the development of plastic sheet production equipment and molds. Mold is an important technological basis for the manufacturing industry. In recent years, the world's mold manufacturing has become increasingly sophisticated and complex. my country's mold industry is also developing rapidly in the direction of informatization, digitization, refinement, high-speed, automation and multi-functionality. There are still some differences between countries. Plastic extrusion molding is a process in which plastic is melted and plasticized in an extruder, and through the rotation of the screw, the material flows through the extrusion molding head to obtain a continuous profile. Therefore, the extrusion molding head is t...
