Abstract

The invention discloses a gearbox cavity die moving die. The gearbox cavity die moving die comprises a moving die base and multiple sliding mechanisms. A first die core matched with the shape of a gearbox is arranged in the middle of the moving die base. A moving die extrusion oil cylinder is arranged on one side of the moving die base. A piston rod of the moving die extrusion oil cylinder vertically faces the moving die base and can be connected with the first die core in an abutting manner. The multiple sliding mechanisms are arranged along the periphery of the moving die base. Each of the multiple sliding mechanisms comprises a sliding cylinder and a sliding die. A piston rod of each sliding cylinder is connected with a corresponding sliding die. Pistons rods of the sliding cylinders vertically face the first die core. A second die core matched with the shape of the gearbox is arranged on a side edge of each sliding die. According to the gearbox cavity die moving die, the moving dieextrusion oil cylinder is arranged on one side of the moving die base, and the multiple sliding mechanisms are arranged; and when a gearbox is cast, accurate location can be conducted on the first die core and the second die cores so that die closing is accurate, and thus the casting precision and quality of the gearbox are improved.

Description

technical field [0001] The invention relates to the field of automobile processing and manufacturing equipment, in particular to a movable mold of a gearbox cavity mold. Background technique [0002] The gearbox is a very important part of the vehicle. It can change the transmission ratio and expand the torque and speed of the driving wheels. Gearboxes are usually cast in cavity molds. The prior art gearbox cavity molds generally require die-casting machines to close and open the molds. However, due to the large movements of the die-casting machines, inaccurate mold closing may occur, which affects the casting accuracy and quality of the gearbox. Contents of the invention [0003] Based on this, the purpose of the present invention is to provide a transmission cavity mold movable mold with the characteristics of simple structure, precise mold clamping, and high casting precision. [0004] The movable mold of the gearbox cavity mold of the present invention comprises a mo...
