Abstract
Vertical closing press for the thermoformable and elastomeric thermoplastic thermoplastic thermoplastic materials, characterized in that it consists of a vertically extending frame, a pair of plates arranged to be moved vertically apart, fluid fast approach means for the plate upper, an injection nozzle extending axially through the lower plate, a transfer chamber for the material integral with said lower plate substantially in axial alignment with said nozzle with which it is in communication; said press is also characterized by the fact that the frame carries, under said transfer chamber, a first vertically disposed cylinder-piston unit whose movable element is integral with said lower plate, said moving element acting as a cylinder for another cylinder unit. Vertically disposed piston, whose shank is on its upper part slidably received and in a sealed manner in said transfer chamber to act thereon as a transfer piston, a screw processing unit integral with said moving element of said cylinder-piston unit first mentioned for loading a predetermined quantity of material treated to said transfer chamber, means for intercepting the load during the injection of the material into the mold and means for disconnecting said transfer chamber and injection nozzle during the loading of the material by the unit of the screw process to the inside of the transfer camera.
