Abstract

The invention relates to a mold base device for pressing a component with a stepped mandrel, which is used for powder metallurgy pressing on a hydraulic press. The mold base comprises a lower central cylinder, an upper fixing template, a put-out feeding-height regulation device, a mandrel-step limit device, a lower fixing template, a bearing plate, a guide key and a connecting bar, wherein the lower central cylinder is arranged on the upper fixing template; the put-out feeding-height regulation device which is connected with the lower central cylinder and is used for regulating feeding height is arranged on the upper fixing template; and the mandrel-step limit device for regulating the height of mandrel steps is arranged on the lower fixing template. Due to the put-out feeding-height regulation device, the feeding height of power can be conveniently regulated; due to the mandrel-step limit device, the limit height of the mandrel steps can be effectively controlled; and due to a stroke controller combined with a limit block, the mold base device can perform powder metallurgy pressing on the stepped mandrel so as to ensure stable machining dimension.

Description

technical field [0001] The invention relates to a device used on a hydraulic press, in particular to a mold base device for pressing a stepped part of a mandrel, which is applied to a lower mold base of a fully automatic dry powder hydraulic press and used for powder metallurgy pressing. Background technique [0002] After retrieving relevant patent documents, a formwork device for pressing a mandrel with a stepped part having the same structure as the present invention has not yet been retrieved. The lower central cylinder of the existing fully automatic dry powder hydraulic machine is all set on the upper output rod of the piston rod of the top cylinder, which cannot be used to press the products with steps on the mandrel, and the scope of use is greatly limited, which cannot meet the needs of actual production. . Contents of the invention [0003] The purpose of the present invention is to provide a lower mold part for the mold base of a fully automatic dry powder hydr...
