FIELD: metallurgy.
SUBSTANCE: cavity of the chamber for forming the part is connected through controlled gate valves to the cavities of the loading vacuum chamber and the vacuum chamber for cooling the part equipped with vacuum systems. The loading vacuum chamber is equipped with a device for loading the workpiece and feeding it to the moulding chamber of the part, and the cooling chamber is provided with a device for moving the part from the chamber to form the part into a cooling chamber equipped with a system for supplying a cooling agent to its cavity. Moreover, the lower half of the stamp is fixed on the table and equipped with the ejector of the molded part, and the upper one - on the rod located in the chamber cavity and equipped with a reciprocating vertical movement drive, the heating elements have an annular shape and cover the upper and lower half of the die, one of the heating elements is mounted on the table, and the other on the rod, the heat shields have an annular shape and cover the heating elements. One of the heat shields is installed on the table, and the other on the rod.
EFFECT: quality of the products is increased due to the reduction of thermal stresses.
