Description

Technical Field

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. Usually, the mold consists of an upper mold and a lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of a press. When the press is opened, a workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as car dashboards can be formed by molds. Mold processing technology includes: cutting dies, blanking dies, compound dies, extrusion dies, four-slide dies, progressive dies, stamping dies, die-cutting dies, etc.; mold types are divided into metal stamping dies: continuous dies, single punch dies, compound dies, stretching dies; plastic molding dies: injection molds, extrusion molds, vacuum dies; die-casting molds; forging molds; powder metallurgy molds and rubber molds.

[0003] Valves are pipe accessories used to open and close pipes, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc., among which the valve body is a major component in the valve; there are different mechanical manufacturing methods according to the pressure level. For example: casting, forging, etc., then the lower valve body processing requires the use of die-casting molds.

[0005] Secondly, the existing die-casting mold structure lacks a cooling system structure. The lower valve body model is formed too slowly after die-casting, and the model is easily damaged when taking materials, which affects the finished product rate and needs to be developed urgently.
