[0002] A reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid housing, and is commonly used as a speed reduction transmission device between a prime mover and a working machine. Among them, a three-stage helical-bevel-helical gear reducer motor has high double-torque efficiency and long-life gears, and is equipped with foot-mounted, flange-mounted, and shaft-mounted types. At present, when processing the housing of a bevel gear reducer, a forming die is required.

[0003] The existing forming die for the housing of a bevel gear reducer still has the following problems when in use: Most of the forming dies for the housing of a bevel gear reducer adopt a single forming structure design for the housing of a bevel gear reducer, which is not conducive to mass production of the housing of a bevel gear reducer. At the same time, after the housing of a bevel gear reducer is formed, when the die is tilted for demolding, the formed die is extremely easy to adhere to the inner wall of the forming groove and is not easy to be automatically demolded by gravity.

At one end of the inner bottom wall of the forming groove 322 is fixedly connected a first forming rod 323. At the four corners of the inner bottom wall of the forming groove 322 are fixedly connected second forming rods 324. The overall forming die mechanism includes three independent forming modules 321, on which is provided a forming groove 322 for the housing of the bevel gear reducer, and is provided with forming rods, which can be used for the casting and cooling forming of a bevel gear reducer housing.
