Share the types and processes of mold processing

Mold Making refers to the processing of forming and blanking tools, in addition to shearing and die-cutting dies. Normally, a mold consists of two parts: an upper die and a lower die. A steel plate is placed between the upper and lower dies and the material is formed under the action of a press. When the press is opened, the workpiece defined by the shape of the die is obtained or the corresponding scrap is removed. Workpieces as small as an electronic connector or as large as an automotive dashboard can be formed with a die. A progressive die is a set of dies that automatically moves the machined workpiece from one station to another and obtains the molded part at the last station. Die processing process includes: cutting die, blanking die, compound die, extrusion die, four-slide die, progressive die, stamping die, die cutting die, etc.

Mold types are:

1. Metal stamping die: continuous die, single punch die, compound die, stretch die

2. Plastic molding die: injection mold, extrusion mold, blister mold

3.Die-casting moulds

4.Forging die

5.Powder metallurgy moulds

6.Rubber moulds

Mould processing process:

Open material: front mold material, back mold material, insert material, line material, slant top material.

Open frame: front die frame, back die frame.

Roughing: front mold cavity roughing, back mold cavity roughing, parting line roughing.

Copper male: front mold copper male, rear mold copper male, parting line clearing angle copper male.

Wire cutting: insert parting line, copper male, inclined top pillow position.
