The invention relates to the improvement of automobile connecting piece molds, in particular to an automobile connecting insert mold. An upper mold of the automobile connecting insert mold comprises a row of mold assemblies arranged in parallel, wherein each mold assembly consists of a base and a quadrangular prism arranged on the base; one side surface of each quadrangular prism adopts a three-stage type stepped shape, and a stepped groove is also formed in the stepped side surface of each quadrangular prism; the surface close to the base, of each stepped groove is an oblique surface; and a circle of exhaust grooves are also formed in the periphery of the base of each mold assembly. Compared with a conventional mold, the automobile connecting insert mold provided by the invention has the characteristics that an insert structure is changed, so that the quality of the mold is improved, and the service life of the mold is prolonged; and through inner test, the service life of the mold can be prolonged by 10-20%, and the situation that burrs are generated on a connecting piece can be avoided.
Description
technical field [0001] The invention relates to the improvement of an automobile connector mold, in particular to an automobile connector insert mold. Background technique [0002] "Front" is a quality term in the plastic industry, which refers to the extra useless parts on the edge of the product, because the extra parts usually hurt the hands a bit, so they have sharp edges. In the plastic industry, it is also called burrs, flashes, and overflowing edges. It usually occurs on the parting surface of the mold, which is caused by the fluidity of the material, the structural defects of the mold, and the improper molding process. [0003] "Insert" is a general term, which specifically refers to the irregular mold accessories used to be embedded in the mold in the mold, which plays the role of fixing the template and filling the space between the templates. [0004] At present, the automobile connection insert molds in the existing technology have various structures, and there...
