Abstract

PURPOSE: To provide a molding machine which enables tremendous increase in injection pressure in inverse proportion to the sectional area of a plasticizing chamber by forming a small plasticizing chamber at the tip of the plasticizing chamber in a pressureproof cylinder with a projection so arranged at a screw head to be inserted closely into the small plasticizing chamber.
CONSTITUTION: A small plasticizing chamber 9 is provided at the tip of a plasticizing chamber 4 in a pressureproof cylinder head 2 and a projection 10 is so arranged at the tip of a head 6 of a screw 5 to be inserted closely into the chamber 9. In the final stage of injection stroke, the projection 10 is inserted closely into the small plasticizing chamber 9 and the screw 5 advances to perform a rapid pressuring. As the injection pressure is inversely proportional to the sectional area of the plasticizing chamber, the sectional area of the small plasticizing chamber 9 can be reduced as compared with that of the plasticizing chamber 4. This ensures a very high injection pressure.
