Cloth hanging mechanism of automobile instrument panel net cloth

Abstract

The invention discloses a cloth hanging mechanism of an automobile instrument panel net cloth. The cloth hanging mechanism comprises a mounting bottom plate (1) and an oil cylinder (2), a fixing plate(3) is arranged on the mounting bottom plate (1), and a mounting cavity (31) is formed in the fixing plate (3); an ejector pin plate (4) is arranged in the mounting cavity (31), a large spring (5) isarranged between the ejector pin plate (4) and the mounting bottom plate (1), and a cloth hanging needle (6) is arranged on the ejector pin plate (4); one end of the cloth hanging needle (6) is limited on the ejector pin plate (4), and the other end penetrates through the fixing plate (3) to extend into a fixed die; an inclined ejection block (7) is arranged at a piston rod of the oil cylinder (2), an inserting groove (8) is formed between the fixing plate (3) and the ejector pin plate (4), and the inclined ejection block (7) slidably abuts in the inserting groove (8). According to the clothhanging mechanism of the automobile instrument panel net cloth, cloth hanging positioning can be carried out accurately and stably, the operation is convenient, and the structure is simple.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an automobile instrument panel mesh cloth hanging cloth mechanism. Background technique [0002] Injection molding process refers to the process of making molten raw materials into products of a certain shape through operations such as pressurization, injection, cooling, and detachment. There are many types of injection molding products, and there are pure plastic products with a slightly simpler process and mold structure. , There are also products with inserts with complex process and mold structure, and mesh cloth is the most common insert. Especially when the airbag part of the automobile instrument panel is injection molded, a layer of mesh cloth needs to be embedded on the surface of the product to meet the use requirements. [0003] In the actual production process, the positioning, placement, and loading of mesh fabrics has become a major problem. At present, there are us...

Problems solved by technology

[0003] In the actual production process, the positioning, placement, and loading of mesh fabrics has become a major problem. At present, there are usually two methods of manual loading or automatic loading of mesh fabrics. Pure manual loading not only slows down the production cycle, but also tends to cause product failures. The mesh is deflected, resulting in poor quality and wasting manpower and material resources; while using the conventional mechanism hanging cloth, there are defects that the mesh is not fixed on the mold or the product surface is dent on the product surface, because the prior art passes Hanging needle In the structure of hanging cloth, the expansion and contraction of the hanging needle in the injection cavity of the fixed mold cannot be well controlled, the degree of automation is not high, and the efficiency is relatively low

This not only wastes raw materials, but also increases the production cycle of the product and reduces the overall production capacity. If the deviation of the product mesh cannot be found and it is treated as a qualified product, there will be a major quality risk
