A kind of die-casting mold for producing shell and the production method of shell

Abstract

The invention relates to the technical field of die-casting molds, and provides a die-casting mold for producing shells and a production method for shells, including: a movable mold assembly, a fixed mold assembly, and a slider mechanism, a movable mold assembly, and a fixed mold assembly The product cavity is formed between the parts and the slider mechanism, and also includes: the runner assembly, the runner assembly has a feed sleeve and a splitter cone arranged on the movable mold assembly, the upper surface of the splitter cone and the lower surface of the fixed mold assembly A feed channel connected with the product cavity is formed between the surfaces, the feed sleeve is connected with the feed channel, the thickness of the feed channel is gradually smaller from the splitter cone to the product cavity, and the feed channel is connected with The junction of the product cavity is in a straight line. Compared with the prior art, the present invention has the advantage that the connection between the feed channel and the product cavity is arranged in a straight line, thereby increasing the feeding speed of the shell and the speed at which the gas is discharged from the product cavity, and preventing the setting on the shell Die-casting defects such as lack of material, air holes, and fluffy structure appear in multiple positioning columns.

Description

technical field [0001] The invention relates to the technical field of die-casting moulds, in particular to a die-casting mould used for producing casings and a production method of the casings. Background technique [0002] Most of the shells are cast by die-casting process. For shells with high dimensional accuracy requirements, the shells are usually machined by machine tools after the casting process is completed to improve the dimensional accuracy of the shells to meet the requirements of the drawings. [0003] like figure 1 The housing 500 shown is also manufactured by first casting and machining, but the structure of this housing 500 is rather special. A plurality of positioning posts 510 are distributed in a matrix on the end face of the housing 500. In the die-casting process, during the die-casting production process of the casing 500, most of these positioning posts 510 will have die-casting defects such as lack of material and pores, and these defects are diffic...

[0003] like figure 1 The housing 500 shown is also manufactured by first casting and machining, but the structure of this housing 500 is relatively special. The end face of the housing 500 is distributed in a matrix with a plurality of positioning columns 510. In the traditional die-casting mold and In the die-casting process, during the die-casting production process of the shell 500, most of these positioning columns 510 will have die-casting defects such as lack of material and air holes, and these defects are difficult to eliminate by adjusting the parameters of the die-casting machine
