Abstract

The invention discloses an extrusion forming type rubber shaping die which comprises a valve elastic rubber sealing pad die body, a raw material feeding opening, a core die body, a core die fixing plate, locating holes, locating pins, an extruding fixing framework, a shield pipeline, a connecting plate and a rubber elastic sealing pad. The left end of the valve elastic rubber sealing pad die bodyis connected with the raw material feeding opening. The valve elastic rubber sealing pad die body is connected with the core die body. The core die body is connected with the core die fixing plate. The upper locating hole and the lower locating hole are formed outside the core die fixing plate. The locating holes are provided with the locating pins. The extrusion forming type rubber shaping die has the beneficial effects that the structure is simple, safety is high, the production efficiency is high, few cylinder residue materials obtained after extruding are left, and resources are saved.

Description

technical field [0001] The invention relates to an extruded rubber molding die, which belongs to the technical field of die equipment. Background technique [0002] The elastic rubber gasket is one of the supporting products of the subway shield machine. It has a relatively small size and a large amount of use. The above elastic rubber gasket is mostly produced by extrusion and microwave vulcanization. Extrusion dies are installed on the extrusion equipment, and the extrusion dies currently used have the following defects: First, the elastic rubber gasket extrusion die includes a single extrusion channel, which has low production efficiency, wastes extruder resources, and causes energy waste , the production cost is greatly increased; secondly, when the extrusion production is completed, the rubber material stranded in the barrel of the extruder is seriously wasted. There are few residual materials left in the cylinder and the advantages of saving resources. Contents of t...
