Adhesion-prevention mobile phone shell extrusion die

Abstract

The invention relates to the technical field of mobile phone shells, and discloses an adhesion-prevention mobile phone shell extrusion die. The die comprises a die body, a forming opening is formed in the front face of the die body, a fixing plate is fixedly connected to the position, below the forming opening, of the front face of the mold body, an air cooler is fixedly mounted on the right side of the top of the fixing plate, a clamping plate is fixedly connected to the position, located on the left side of the air cooler, of the top of the fixing plate, a through opening is formed in the left side of the clamping plate, the clamping plate penetrates the through opening, a cold air net is fixedly connected with the position, corresponding to the air cooler, of the inner wall of the through opening, a first electric push rod is fixedly mounted on the left side of the top of the fixing plate, the output end of the first electric push rod is fixedly connected with a clamping plate, and the clamping plate is movably connected with the fixing plate. The adhesion-prevention mobile phone shell extrusion die is simple in structure, the adhesion condition during mobile phone shell forming is prevented, the forming speed and forming stability are better improved, and the forming efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of extrusion dies, in particular to an anti-adhesion extrusion die for mobile phone shells. Background technique [0002] At present, the commonly used plastic materials for mobile phone casings mainly include PC, ABS and PC+ABS. Japanese mobile phones mainly use PC+ABS, and even use ABS as mobile phone casings. Several Korean mobile phone manufacturers were the first to use pure PC materials, and advocated the use of PC+ ABS materials, but in the past one or two years, PC materials suitable for mobile phone casings have also been introduced. In recent years, the proportion of major mobile phone manufacturers using Pc materials for mobile phone casings is gradually increasing, no matter in terms of mold design, injection molding technology or coating performance. There have been great breakthroughs. The proportion of mobile phone shells made of PC materials is on the rise. According to preliminary estimates,...
