A die-casting mold for the production of gearboxes

Abstract

The invention relates to a die-casting mold for producing gearboxes, which includes a mold body, a core-pulling structure and a gate structure. The front, rear, left, and right sides of the mold body are equipped with core-pulling structures inserted into the mold cavity. The mold body The left and right parts of the upper mold base are respectively equipped with a material handle cutting structure and a gate structure. The mold cavity is surrounded by an upper mold core, a lower mold core and four core-pulling structures. The middle part of the lower mold core is installed There is a cylindrical boss structure with a small upper part and a larger bottom part, which is stepped. The cylindrical boss structure is vertically equipped with an introduction sleeve structure whose upper end communicates with the gate structure. The introduction sleeve structure includes a sleeve and a splitter cone. The invention has the characteristics of improving product quality, ensuring rapid production of products, increasing service life of molds, improving production efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of gearbox processing, in particular to a die-casting mold for producing gearboxes. Background technique [0002] The gearbox structure is usually produced by die-casting molds in the production process, but the quality of the gearbox is usually not guaranteed when the die-casting mold is produced. During the production process of the die-casting mold, the wall structure will appear flashing phenomenon, which will cause the product to be scrapped. In addition, when the ejector pin is ejected, the thin-walled structure will usually be bent by the thrust of the ejector pin, resulting in product deformation. In order to solve the above problems, It is very necessary to design a new processing technology. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a die-casting mold for producing gearboxes, which has the characteristics of improving product qua...

[0002] The gearbox structure is usually produced by die-casting molds in the production process, but the quality of the gearbox is usually not guaranteed when the die-casting mold is produced. During the production process of the die-casting mold, the wall structure will have flashing phenomenon, which will cause the product to be scrapped. In addition, when the thimble is ejected, the thin-walled structure will usually be bent by the thrust of the thimble, resulting in product deformation. In order to solve the above problems, It is very necessary to design a new processing technology
