Description

Technical Field

[0001] The utility model relates to the field of mold equipment, in particular to a forging mold for automobile pin body accessories. Background Art

[0002] Forging is forging, which is a processing method that uses forging machinery to apply pressure to metal blanks to make them plastically deform to obtain forgings with certain mechanical properties, certain shapes and sizes. With the increasing number of cars, pins are often used in the assembly and maintenance of cars to play a role in connection and fixing. In the prior art, the lower die A in the lower die fixed body of the original steel plate pin forging die is an integral body. Since the working part of the lower die A is the inner cavity of the component, the working parts of the inner cavity are subjected to different deformation pressures of the workpiece. Therefore, if the material hardness of the original integral lower die A is too high, it is easy to break during operation. If the material hardness is too low, it is easy to deform and fail during operation. Among them, the application number "CN201120346300.7" is a split forging steel plate pin die, block, the utility model has a reasonable structural design, uses high-hardness materials, and a block-type assembly structure, which not only ensures the strength of the workpiece, but also enables each block to play a certain buffering role when subjected to unequal working forces. Such a die structure greatly improves the service life of the die. However, there is still room for improvement in the use of this mold: due to the high surface temperature of the pin body, slag will fall during forging, posing a risk of scalding to personnel, and the mold does not have an ejection structure, so the workpiece needs to be manually clamped for removal after forging is completed.
