Both the backing plate and the backing plate of the upper machine base are intersected with threaded holes. Threaded holes are used to fix various molds.

The piston on the hydraulic cylinder is fixedly connected with the supporting plate of the lifting platform.

Its working principle is: the hydraulic cylinder and the hydraulic pump are connected through a hose, the outlet valve of the hydraulic pump is opened, and the high-pressure oil enters the hydraulic cylinder to drive the piston in the hydraulic cylinder to move upward. Jack up the entire lifting platform, the lifting platform moves vertically up and down along the guide rod, the lower part of the mold is installed on the backing plate, the upper part of the mold is installed on the backing plate of the upper machine base, the two are coaxial, and the raw materials of the formed parts are placed on the mold On the lower part, when the lower mold is driven by the hydraulic cylinder and the upper mold is quickly approached, the forming material sandwiched between the two is quickly formed under the action of extrusion force. After the forming is completed, only the hydraulic pump is connected to the hydraulic pressure. When the inlet valve of the cylinder is closed, the lifting platform will return to its original position under the action of its own weight, and the lifting platform will fall on the buffer pad to complete the forming process of the raw material of the formed part.

The beneficial effects of the utility model are: the utility model has the advantages of simple structure, easy operation and wide application range. After completion, the lifting platform can return to its original position by its own weight, and the operation is easier; the lifting platform falls on the cushion pad to avoid collision with the lower machine base, and has a long service life; the cushion pad is easy to replace and saves costs; the disc with threaded holes Shaped backing plate, can be applied to many kinds of molds, as long as the mold is fixed on the backing plate through the threaded hole, the molding of various complex shape parts can be realized, especially for round and quasi-circular parts; the stamping force is large and uniform, simple The unique design of the upper and lower bases ensures that the force of the entire hydraulic press is reasonable and saves equipment manufacturing costs.
