Rubber supply device for low-pressure injection molding equipment

Abstract

The invention provides a rubber supply device for low-pressure injection molding equipment, and relates to the technical field of wire harness machining. The rubber supply device comprises a machine body, a supporting frame, electric heating net plates and a heat insulation inner container; the top of the machine body is provided with a feeding inlet, and a top cover is hinged to the top of the machine body; the heat insulation inner container is cylindrical, the inner wall of the heat insulation inner container is provided with a plurality of step surfaces, and in addition, the inner diameterof the step surfaces is sequentially increased from bottom to top; the electric heating net plates are placed on the step surfaces, and moreover, the hole diameter of the electric heating net platesis sequentially increased from bottom to top; the bottom of the heat insulation inner container is provided with a rubber outlet; and a spiral discharging mechanism is installed at the rubber outlet.According to the rubber supply device, the structural design with the multiple layers of electric heating net plates is adopted, a rubber raw material can be heated step by step, meanwhile, the heating temperature of each electric heating net plate can be controlled as required, thus, the electric heating net plates can meet different heating requirements, the rubber can be uniformly heated to bein the flow state, and the phenomenon of blockage at the rubber outlet is decreased.

Description

technical field [0001] The invention relates to the technical field of wire harness processing, in particular to a glue supply device for low-pressure injection molding equipment. Background technique [0002] The wire harness terminal is an important part of the automobile wire harness. Most of the current wire harness terminals are made of plastic materials, and some of them need to be injection-molded to add some anti-falling structures on the basis of the original plastic parts. This requires the use of low-pressure injection molding equipment. The rubber material is the raw material of the wire harness terminal, which is a liquid material heated by rubber heating equipment. The current heating equipment is prone to blockage during the heating of rubber. [0003] The Chinese Patent Publication No. CN207053822U discloses an electromagnetic heating device for rubber equipment, which includes a main body. The side surface of the main body is provided with a PLC controller. ...

Problems solved by technology

[0004] Although the above-mentioned device can realize heating work, its heating area is limited after all. The overall heating of the rubber is mostly in the form of heat transfer. The rubber in some areas is not heated to a fluid state, which is prone to clogging in the later stage.
