Abstract

The invention belongs to the technical field of car part manufacturing and particularly relates to a manufacturing method of a vehicle speed changing box module. The method comprises the following steps that 1, according to a three-dimensional model of the vehicle speed changing box part design mould, layering and slicing are carried out on the three-dimensional model, and the mould comprises a base portion, a buffering portion and a forming portion; 2, parameters of the three-dimensional model of the mould are input into 3D printing equipment, and the base portion of the mould is printed andobtained; 3, the buffering portion is printed on the base portion; 4, the forming portion is printed on the buffering portion; and 5, surface treatment is carried out on the forming portion. Accordingto the method, multiple first blind holes are formed in the upper surface of the base portion, first protrusions corresponding to first blind holes correspondingly are arranged on the lower surface of the buffering portion, the upper surface of the buffering portion is provided with multiple second protrusions with the axis not coinciding with that of the first protrusions, and second blind holescorresponding to the second protrusions are formed in the lower surface of the forming portion. The method well solves the problems that for existing vehicle speed changing box part moulds, the development period is long, the service life is shortened gradually, and the precision is reduced gradually.

Description

technical field [0001] The invention belongs to the technical field of automobile parts manufacturing, and in particular relates to a method for manufacturing a vehicle transmission 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. With the development of modern technology, the transmission has also been upgraded, from the initial manual transmission, to automatic transmission and continuously variable transmission, and then to the current dual-clutch transmission, from without synchronizer to with synchronizer, the control is getting better and better. It is more and more convenient, its internal structure is more and more complex, and the precision requirements are getting higher and higher. [0003] Various parts of the vehicle gearbox are usually molded in the manufacturing process, such as the automatic gearbox shell mold, the gearbox cover...
