AUGER PLASTICATOR FOR INJECTION MOLDING POLYMERS Russian patent published in 2019 - IPC B29C48/52 B29C48/525 B29C48/53 B29C48/535 B29C48/54 B29C48/80 

FIELD: technological processes.

SUBSTANCE: invention relates to plastic injection molding device. Technical result is achieved by a device for plastic injection molding, which comprises a plasticator, a melt accumulator, a loading pocket, a heating element and a transporting screw. At the same time transporting screw is assembled of separate parts fixed on shaft with possibility of axial and rotary movement, and combining cylindrical and conical forms of structure. Pitch, depth and number of teeth of the screw parts are different. Heating element represents electrodes for heating by high-frequency electromagnetic field, made in the form of annular external electrode, inside of which there is screw, one of which parts is internal electrode fixed on shaft key.

EFFECT: increased accuracy of heating temperature and degree of compression of liquid plastic, reduced power consumption and material consumption, reduced cycle of casting and increased efficiency.
