Z-axis linear motor quality block shaping mold and assembly method thereof

Abstract

A Z-axis linear motor mass block shaping mold and an assembly method thereof, aiming at solving the problem that the integrated shaping mold needs to be replaced after the wear of the integrated shaping mold in the prior art, the maintenance cost is high, and the overall size of the mold is large. Technical issues with low usability. The present invention includes a mold assembly and a mold base assembly. The mold assembly includes a die, an upper punch, a lower punch and a mandrel. The die is formed by splicing an upper die and a lower die. Fixing parts, lower punch fixing parts and mandrel fixing parts, upper punch fixing parts and mandrel fixing parts are coaxially arranged after being positioned by the guide post, upper punch and lower punch are arranged at intervals along the length direction of the guide post, lower punch fixing parts, core Both the bar holder and the upper punch holder are attached to the punch press.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a Z-axis linear motor quality block shaping mold and an assembly method thereof. Background technique [0002] The Chinese patent with application number CN201720913316.9 introduces the production process of mass blocks for mobile phone motors in the background technology. Specifically, the current commonly used preparation method is to put tungsten-based alloy powder into a mold and form it under a certain pressure Form a compact, and then sinter the compact at high temperature to obtain a mobile phone mass; however, due to the large aspect ratio of the mobile phone mass, it is not easy to obtain a compact with uniform density, and the size of the compact may be distorted after sintering and shrinkage , the shape and precision of the mass block are difficult to control; furthermore, compared with the disordered vibration direction of the traditional motor, the vibrat...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the technical problems in the prior art that the integral mold needs to be replaced after the integrated plastic mold is worn out, the maintenance cost is high, and the overall size of the mold is large, the convenience of use is not high, and the present invention provides a Z-axis The permanent motor mass block shaping mold and its assembly method, the die adopts the split design of the upper die and the lower die, and only need to replace the lower die or the upper die during maintenance, the maintenance cost is greatly reduced, and in addition , the die is directly made of cemented carbide, without inserting treatment, the overall size of the die is small, which reduces the manufacturing cost of the plastic mold while improving the convenience of use
