Abstract

The invention discloses a die for machining a powder metallurgy multi-step part. The die comprises a female die and a puncher pin die assembly. The female die comprises a female die body and a die sleeve for fixing the part. A first through hole is formed in the die sleeve. The puncher pin die assembly comprises a first puncher pin die, a second puncher pin die, a third puncher pin die, a fourth puncher pin die and a fifth puncher pin die, wherein the second puncher pin die is located above the first through hole and provided with a second through hole which the first puncher pin die is allowed to enter, the third puncher pin die is located below the first through hole and provided with a third through hole which the fourth puncher pin die is allowed to enter, and the fourth puncher pin die is provided with a fourth through hole which the fifth puncher pin die is allowed to enter. According to the die, the powder metallurgy multi-step part can be simultaneously machined and formed at a time, the machining size is precise, and the cost is reduced.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for processing powder metallurgy multi-step parts. Background technique [0002] Mold, various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. In short, a mold is a tool used to shape an object. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. [0003] Powder metallurgy is an industrial technology for producing metal powder or using metal powder (or a mixture of metal powder and non-metal powder) as raw material, forming and sintering to produce metal materials, composite materials and various types of products. At present, powder metallurgy technology has been widely u...
