Title:
EXTRUSION DIE, APPARATUS AND METHOD FOR IMPLEMENTING BIDIRECTIONAL EXTRUSION MOLDING PROCESS
Document Type and Number:
WIPO Patent Application WO/2021/169513
Kind Code:
A1
Abstract:
An extrusion die, apparatus and method for implementing a bidirectional extrusion molding process, relating to the field of dies. The apparatus comprises an extruder center cross beam (1), a first extrusion cylinder (5), a second extrusion cylinder (6), a push-pull rod (9), and an extrusion die for implementing a bidirectional extrusion molding process. The push-pull rod (9) is fixedly connected to a male die (8). The first side surface and second side surface of the extruder center beam (1) are respectively provided with a first extrusion cylinder inlet (3-001) and a second extrusion cylinder inlet (3-002). After the extrusion die for implementing a bidirectional extrusion molding process enters a die inlet/outlet (3-004), the first extrusion cylinder (5) passes through the first extrusion cylinder inlet (3-001) and is in contact with the first side surface of the male die (8), and the second extrusion cylinder (6) passes through the second extrusion cylinder inlet (3-002) and is in contact with the second side surface of the male die (8). The die, apparatus and method can solve the problems of die disassembly and assembly, material feeding, bidirectional extrusion action, and surplus shearing in the current implementation of a bidirectional extrusion process.
