Abstract

The invention discloses a novel die for the injection molding of mobile phone cases. The die includes a transmission case; one side on the bottom end inside the transmission case is provided with a supporting plate; the supporting plate is provided with a transmission gear; one side of the transmission gear is in coaxial connection with a belt pulley; the belt pulley is connected to a belt; and the other end of the belt is connected to the output shaft of a speed reducer located on one side at the upper part inside the transmission case. The transmission case can be fixed through a supportingframe, and is detachably connected to a fixed clamping plate, and connecting and fixing can be realized through the cooperation of locating pieces and fixing pins during connection; the locating pieces can also realize the fast positioning of the fixed clamping plate and a moving die plate, so that the processing efficiency of injection molds can be increased; and during separation, the separationof the moving die plate and the fixed clamping plate can be realized by only rotating the fixing pins to take out, so that convenient storage of the injection molds can be achieved, and fast connecting and fixing efficiency, small occupation areas and convenient usage can be realized.

Description

technical field [0001] The invention relates to the technical field of molds for injection molding, in particular to a novel mold for injection molding of mobile phone shells. Background technique [0002] Mobile phone is a communication device widely used in modern society, and the shell of mobile phone is generally made of injection molding. For the lower part of the mobile phone shell, it should have a certain structural strength. There are cameras and flash lights on the back, so a certain amount of through holes should be left. , since the plastic part is a mobile phone casing, the requirements for surface roughness are not high. [0003] After searching, the Chinese patent authorization number CN206510340U discloses a mobile phone shell injection mold, including a fixed mold base plate, a die groove is opened above the fixed mold base plate, and a feed channel is opened on the top of the side of the die groove. There are two guide columns arranged in parallel on the t...
