Shell Extrusion Pressing Die

Abstract

The invention belongs to the technical field of molds and particularly discloses a hole extrusion and label stamping mold for a motor shell. The hole extrusion and label stamping mold comprises a rack. The rack is provided with a lower mold holder and an upper mold holder, wherein the lower mold holder is stationary, and the upper mold holder can be close to or away from the lower mold holder. Theupper mold holder is provided with an annular female mold. The lower holder is provided with a male mold. The male mold comprises a large-diameter end and a small-diameter end, wherein the large-diameter end and the small-diameter end are coaxially arranged. The large-diameter end is fixedly connected to the lower mold holder, and the small-diameter end is located at the end of the large-diameterend. The small-diameter end is sleeved with a labeling mold. Material returning rods are connected below the labeling mold. The lower ends of the material returning rods penetrate the large-diameterend and the lower mold holder and are connected with an elastic demolding mechanism. Compared with the prior art, according to the hole extrusion and label stamping mold, two types of operation, namely hole extrusion and label stamping, of the motor shell are implemented at the same time, operation procedures are reduced, and demolding of the motor shell is achieved through the elastic demolding mechanism, the material returning rods and the labeling mold; the motor shell is prevented from being tightly clamped onto the male mold, and discharging can be conducted conveniently; the lower mold holder does not need to be knocked manually for demolding; the labor intensity of workers is lowered; and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of moulds, and specifically discloses a casing extrusion hole pressing die. Background technique [0002] With the continuous expansion of market demand, motorcycles have become a common means of transportation for the majority of urban and rural residents, followed by a sharp increase in the variety and output of motorcycle motors. The casing is an important part of the motor. The casing of the motor determines the relative position of the stator and the rotor in the motor. The manufacturing quality of the casing directly affects the performance of the motor such as output power, operating noise and heat generation. Therefore, on the premise of ensuring the quality of the casing, it is particularly important to shorten its production cycle, improve production efficiency, and then reduce costs. [0003] In the process of preparing the motor casing, it is often necessary to perform two operations on the casi...
