FIELD: glass industry; production of glassware.
SUBSTANCE: the invention is dealt with the field of glass industry, in particular, with machines for molding glassware. The invention ensures improved stability of control over the temperature on a casting mold surface. The casting mould for molding glassware contains at least one body made as a single whole with a heat-conducting system having a central section with a surface of molding to shape a molten glass and with its longitudinal axis along a casting mold axis and a peripheral section spread in radial directions outside with regard to the central section; a set of passes for a refrigerant located in the peripheral section in parallel to the casting mould axis and to each other along a circumference with intervals in respect to each other intended for a reception of the refrigerant and removal of heat from the body and from the molding surface by a means of a heat transfer; and a set of cylindrical holes in the body located in parallel to the axis of the casting mold, to each other and to the passes for the refrigerant. Each pass has an entry from one butt of the body of the casting mold in direction along the axis of the butt of the body and an exit from another butt of the body in direction along the axis of the butt of the body of the casting mold with a capability to maintain a circulation of the refrigerant through the indicated passes. Each of the cylindrical holes passes at least through one of the butts of the casting mold body along its axis. The holes are located in a radial direction between, at least, some of the passes for the refrigerant and the surface of molding with maintenance of a heat transfer from this surface to refrigerant during its passing through.
EFFECT: the invention ensures improved stability of control over the temperature on a casting mold surface.
