Injection molding mold for micro motor framework

Abstract

The micro motor framework injection molding mold comprises a lower mold base and an upper mold base arranged above the lower mold base, a forming groove with a notch formed in the upper end face of the lower mold base is formed in the lower mold base, a piston cavity is formed in the upper mold base, and a piston is slidably connected into the piston cavity; the piston is provided with a linear reciprocating motion mechanism controlling the piston to vertically move up and down, the upper die base is provided with a blocking piece forming channel, one end of the blocking piece forming channel is communicated with the forming groove, and the other end of the blocking piece forming channel is communicated with the piston cavity. A profiling separation blade forming block is slidably connected into the separation blade forming channel, one end of the profiling separation blade forming block is connected with the piston, the other end of the profiling separation blade forming block is flush with the lower end face of the upper die base, and a balance air channel enabling the piston cavity to be communicated with the outside is further formed in the upper die base. The injection molding mold has the characteristics of novel structure and high molding quality, and is complete in overall function and high in practicability.

Description

technical field [0001] The invention relates to the technical field of mold manufacturing, more specifically, it relates to a micro-motor frame injection molding mold. Background technique [0002] Such as Figure 4 As shown, it is a structural schematic diagram of an existing micro-motor skeleton, which includes a ring-shaped skeleton body 100, and twelve vertical baffles distributed in a circular array at equal intervals are arranged on the end face of the skeleton body 100. 101, the cross-section of the vertical baffle 101 is C-like, the wall thickness is small, the injection molding process requires high injection pressure for raw materials, and there is still a high probability of output under the condition of maintaining a high injection pressure Substandard products, the overall effect is not good. Accordingly, the present invention proposes a micro-motor frame injection mold. Contents of the invention [0003] The object of the present invention is to overcome th...
