High-precision powder injection mold with locking function

Abstract

The high-precision powder injection mold with the locking function comprises a base box, a lower mold body and an upper mold body, insertion teeth are fixedly connected to the bottom of the upper mold body and inserted into positioning grooves formed in the top of the lower mold body, straight teeth are symmetrically installed on the two sides of the upper mold body, and a lock installation base is installed above the base box; gears meshed with the straight teeth are symmetrically installed on the inner side of the lock installation base, the gears are fixedly connected with a fixing disc through fixing shafts, a sliding ring is installed on the inner side of the fixing disc and connected with the lock installation base through an elastic piece, and a sliding block is installed on one side of the sliding ring. An inner gear ring and an outer gear ring which are meshed in tooth face are installed between the outer side of the sliding ring and the inner side face of the fixing disc, teeth contained in the outer gear ring are inclined faces in the direction of rotating towards the middle of the base box along the fixing disc, and the opposite rotating direction is a vertical face perpendicular to the inner side face of the fixing disc. The safety intensity is high, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of powder injection, in particular to a high-precision powder injection mold with a locking function. Background technique [0002] In the process of integral molding of the workpiece, the raw material powder is often injected into the mold, and then the powder is combined and formed by extrusion (mostly accompanied by heating). During this preparation process, the mold must bear a certain pressure. In order to improve the mold The bonding strength of the installation is usually limited and locked by the telescopic rod. During the installation process of the mold, personnel need to control the telescopic rod to be inserted into the locking slot after the upper and lower molds are engaged. In this way, the telescopic rod is used many times. Afterwards, it is easy to deform and affect the strength of mold installation and locking. Manual control is required during installation, resulting in low operating effic...
