Plastic injection mould for mobile phone shell

Abstract

The invention relates to a plastic injection mould for a mobile phone shell. The plastic injection mould comprises a movable mould side machine fixing plate, a fixed mould side machine fixing plate, a male mould plate and a female mould plate, wherein the male mould plate and the female mould plate are encircled to form a cavity; the male mould plate is fixedly provided with a first inverted hook matched with an inverted buckle at one end of the mobile phone shell, the lower end of the first inverted hook is connected with an ejector rod, a fixed plate is fixedly provided with a second inverted hook matched with another inverted buckle at the other end of the mobile phone shell; the fixed plate is fixedly provided with a first inclined stretching tip and a second inclined stretching tip; the female mould plate is provided with a first sliding block and a second sliding block; and a first avoidance hole matched with the first inclined stretching tip is formed in the first sliding block, and a second avoidance hole matched with the second inclined stretching tip is formed in the second sliding block. According to the plastic injection mould for the mobile phone shell disclosed by the invention, mutually matched avoidance mechanisms are arranged on the male mould plate and the female mould plate, so that the plastic injection processing of the inverted buckle parts of the mobile phone shell becomes feasible and simple; and moreover, the plastic injection mould is simple in mould opening working procedure and high in processing efficiency.

Description

Technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a mobile phone shell. Background technique [0002] The level of mold technology is an important indicator of the level of manufacturing. In Japan, molds are called "the driving force for entering a wealthy society"; in Germany, molds are called "the emperor of the metal processing industry." In China, mold has always been called the "mother of all industries". The output value of the final product formed by the mold is hundreds of times the output value of the mold itself. The high precision, high complexity, high consistency, high productivity and low consumption demonstrated by using molds to produce parts are unmatched by other manufacturing methods. Therefore, the mold is also called "benefit amplifier". Some people compare the mold to a "money printing machine."

Problems solved by technology

[0003] However, the existing mobile phone shell injection molds can only process products with simple structures

For some products with complex structures, especially mobile phone cases with undercuts, traditional injection molds cannot be used to complete their processing

This requires the use of special injection molds for processing, and special injection molds often have the disadvantages of cumbersome mold opening process and poor processing efficiency.
