An automatic mold unloading mold for one-way press

Abstract

The invention belongs to an automatic die unloading die for a one-way press. The automatic die unloading die comprises an upper sizing block, a die sleeve, a supporting plate and a bottom plate from top to bottom and also comprises a supporting elastomer, wherein a die cavity is arranged in the die sleeve; an upper pressure head and a lower pressure head are arranged in the die cavity; a hole for allowing the supporting elastomer to pass through is formed in the supporting plate; the upper and lower ends of the supporting elastomer are respectively fixed on the die sleeve and the bottom plate; a through hole is formed in the supporting plate; an inner boss is arranged at the inner side of the upper part of the through hole; an outer boss is arranged at the bottom of the lower pressure head and is located in the through hole and below the inner boss; the external diameter of the outer boss is larger than that of the inner boss; and one end of a die unloading elasticity is fixedly arranged at the bottom plate located below the through hole, and the other end of the die unloading elastomer is fixedly arranged at the bottom of the lower pressure head. In the pressure relief process of the press, the automatic die unloading process is realized, the finished product die unloading quality is stabilized, the production efficiency is increased, the operation safety is improved, and the automatic die unloading die has high economic benefits and practical values.

Description

technical field [0001] The invention belongs to the technical field of powder molding, and in particular relates to an automatic mold unloading mold used on a one-way press. Background technique [0002] The compression molding of metal powder, ceramic powder, resin powder or mixed powder is generally realized by using a special molding mold in a one-way press, and often adopts a constant volume molding method. The molding process first puts the powder in the In the mold cavity, add relevant shims; then use a one-way press to apply pressure to the mold head to press the powder into the designed shape and size. For example, the Chinese patent "A Die for Bidirectional Compression Forming on a Unidirectional Press" (CN201420217124.0) provides a mold that realizes synchronous bidirectional pressing without removing the lower shim, but the patent's The solution does not completely eliminate the lower shim iron, and there is still the operation of setting the lower shim iron in t...
