The working principle of the utility model is as follows: when stamping work is required, firstly, raw materials of the support base are placed on the material placing groove of the stripper plate, then the upper template is controlled to move downwards, so that the material pressing plate and the convex mold core are driven to move downwards together, at the moment, the material pressing plate can firstly press the raw materials, the raw materials are guaranteed to be stable and immobile, the final result of the operation is that the flat part of the support base can be formed, the upper template continuously moves downwards and is pressed in place, meanwhile, the lifting device controls the convex mold core to continuously move downwards, and the concave arc and the convex arc of the support base are respectively formed through the mold cavity and the arc part protruding outwards; when the die is separated, the upper die plate moves upwards, the stripper plate can lift the stripper plate upwards under the action of the spring, and the stripper plate can be prevented from excessively moving through the bolt, so that the smooth demolding of the support base is finally realized.

The support base has the advantages that the structure is reasonable, the design is standard, the die cavity formed by combining the convex die core and the groove part and the arc part protruding outwards form the inner concave arc and the outer convex arc of the support base respectively, and the flat part of the support base is formed by matching the material pressing plate and the material placing groove, so that the support base can be formed smoothly, and the production requirement is met. The lifting device is used for controlling the rising or falling motion of the male die core, the mounting plate is used for connecting the upper half part of the device with a machine, the pressure plate can compress and fix the raw materials of the support base to keep the raw materials at a stable position, and the supporting columns are arranged between the mounting plate and the upper die plate and between the pressure plate and the upper die plate and are mainly used for bearing the moment generated by the mounting plate, the upper die plate and the pressure plate in the motion process to support the motion.
