Z-axis linear motor mass block forming die

Abstract

The invention relates to a Z-axis linear motor mass block forming die, and aims to solve the technical problems that in the prior art, when a traditional forming die is used for processing a mass block with steps, the density uniformity of a product is poor, the manufacturing difficulty of the forming die is large, and the die debugging and mounting efficiency is low. The die comprises a die assembly and a die frame assembly, wherein the die assembly comprises a female die, an upper punch, a lower punch and a core rod, the female die comprises an upper female die body and a lower female die body, the die frame assembly comprises a lower female die fixing piece used for limiting the lower female die body, the lower punch comprises a first machining section and a second machining section inthe length direction of the lower punch, the upper punch, the female die and the lower punch are coaxially arranged, the core rod can slide into or out of an upper punch forming hole of the upper punch, the lower female die body partially penetrates into an upper female die forming hole of the upper female die body, the upper female die body is higher than the lower female die body, and the upperfemale die body and the lower female die body are matched to form a female die step coaxial with the core rod.

Description

technical field [0001] The invention relates to the technical field of motor manufacturing, in particular to a Z-axis linear motor quality block molding die. Background technique [0002] Mobile phone vibration motor mass (counterweight) products are divided into several categories: flat motor mass, iron core motor mass and linear motor mass, linear motor mass includes X axis (horizontal) and Z axis (vertical), Among them, the flat motor mass and the iron core motor mass are traditional products with low dimensional accuracy requirements and mature production process, while the linear motor mass generally requires higher dimensional accuracy. [0003] The Chinese patent with the application number CN201822218199.1 discloses a multi-stage powder metallurgy clutch housing shaping mold, including a fixed ratchet, and an improved mold assembly is installed in the middle of the fixed ratchet; the improved mold assembly includes an upper punch body, a second The lower punch body,...
