The invention discloses a die for a lead frame of an automobile seven-gear gearbox. The die which comprises a bottom plate, a lower die mounting base is fixed to the upper side of the bottom plate, alower die is mounted in the middle of the upper side of the lower die mounting base, first clamping grooves are formed in the left side and the right side of the lower die, and first clamping blocks are matched with the first clamping grooves. The outer end of a first lead screw is connected with a first rotating block, supporting columns are fixed to the four corners of the upper side surface ofthe lower die mounting base, the tops of the four supporting columns are jointly connected with a top plate, a hydraulic cylinder is fixed to the middle of the lower side of the top plate, and the telescopic end of the hydraulic cylinder is connected with an upper die mounting base. An upper die is mounted in the middle of the lower side of the upper die mounting base, and second clamping groovesare formed in the left side and the right side of the upper die correspondingly. According to the die for the lead frame of the automobile seven-gear gearbox, the lower die and the upper die are easyto assemble and convenient to disassemble, other auxiliary tools are not needed, the operation is quick and convenient, time and labor are saved, and the disassembling and assembling efficiency is effectively improved.
Description
technical field [0001] The invention relates to the field of auto parts processing, in particular to a mold for a lead frame of an automobile seven-speed gearbox. Background technique [0002] The transmission is one of the main components of the car transmission system. Automobile gearboxes are often called "gearboxes" in automobiles; they are often called "speed changers" in industrial machinery, and they are mechanical or hydraulic equipment for mechanical power conversion. Speed changer is made up of speed change transmission mechanism and operating mechanism, and power take-off can also be installed when necessary. There are two ways of classification: according to the transmission ratio change method and according to the different manipulation methods. [0003] At present, the molds of the existing gearbox lead frames are all fixedly connected to the mold mounting base by bolts, which is cumbersome to install, and when the mold is damaged, it is very inconvenient t...
