Mobile phone shell injection mould with safety hook

Abstract

The invention relates to a mobile phone shell injection mould with a safety hook. The mobile phone shell injection mould comprises a male template and a female template; the female template and the male template form a cavity in an encircling manner; a first inclined extension tip and a second inclined extension tip are fixedly installed on a fixed plate; a first sliding block and a second sliding block are arranged on the male template; a first avoidance hole matched with the first inclined extension tip is formed in the first sliding block; a second avoidance hole matched with the second inclined extension tip is formed in the second sliding block; a third sliding block is arranged on the male template; a wedge-shaped hole is formed in the third sliding block; a guide column, the end part of which is wedge-shaped, is fixedly installed on the female template; the safety hook is arranged on the female template; a fifth spring is installed on the female template; a fourth sliding block is arranged on the male template; and a support column, the end part of which is wedge-shaped, is installed on the fixed plate. According to the mobile phone shell injection mould disclosed by the invention, mutually matched avoidance mechanisms are arranged on the male template and the female template, therefore, injection processing of a mobile phone shell reverse buckling part is viable and simple; furthermore, the mobile phone shell injection mould disclosed by the invention is simple in mould-opening process 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 case with a safety hook. Background technique [0002] The level of mold technology is an important symbol to measure the level of manufacturing industry. In Japan, molds are called "the driving force for entering a wealthy society"; in Germany, molds are called "the emperor in the metal processing industry". Mold has always been called "the mother of all industries" in China. 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 shown by the production of parts with molds are unmatched by other processing and manufacturing methods. Therefore, the mold is also called "benefit amplifier". Some people also compare the mold to a "money printing machine". [0003] However, the existing mobile phone shell...

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.
