Shaping jig for powder metallurgy

Abstract

The invention belongs to the technical field of shaping jigs and discloses a shaping jig for powder metallurgy. The shaping jig comprises a heating base mechanism, a first jig body, a powder filling opening, a second jig body, a handle and a positioning shaft, wherein the powder filling opening is formed in the bottom of the first jig body; a first shaping plate matched with a second shaping plateis movably arranged at the bottom of the cavity of the first jig body; radiating holes are uniformly formed in the outer wall of the front side of the second jig body; and matching radiating hole sealing mechanisms are arranged at the radiating holes. According to the shaping jig, the radiating hole sealing mechanisms are arranged, when the radiating holes need to be opened, a servo motor is started to rotate anticlockwise, the servo motor drives a rotary rod to rotate, the rotary rod drives a plurality of groups of movable rods to synchronously rotate in the same direction through matching of a driving bevel gear and a driven bevel gear to further drive a support block and a sealing separation blade to rotate anticlockwise to open the radiating hole for heat dissipation, manual operationis not adopted, and the using potential safety hazard is reduced while greatly saving labor force.

Description

technical field [0001] The invention relates to the technical field of shaping fixtures, in particular to a shaping fixture for powder metallurgy. Background technique [0002] 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 used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the most dynamic branches of new material science. Powder metallurgy technology has a series of advantages such as significant energy saving, material saving, excellent performance, high product precision and good stability, and is very suitable for mass production.

AI Technical Summary

Problems solved by technology

[0003] Existing orthopedic fixtures need to dissipate heat after heating, and most of them use heat dissipation holes. In order to avoid internal heat loss during heating, most of them use sealing plugs or baffles to be screwed at the heat dissipation holes. Opening one by one not only increases the labor intensity, but also makes it easy for users to be affected by high-temperature burns, which poses a greater safety hazard. For this reason, we propose a plastic jig for powder metallurgy
