Abstract

953,217. Injection moulding. H. GOLLER, and N, CHATELET, [trading as ANKERWERK GEB. GOLLER]. Dec. 23, 1960 [Dee. 24, 1959], No. 44217/60. Heading B5A. An injection moulding machine comprises a rotatable and axially movable screw 2, Fig. 1, which is tapered at its free end, the adjacent inner wall of the housing also being tapered. In operation the screw 2 is axially located in the position wherein the tip 24, 25, Fig. 5, closes the discharge opening 6 and is then rotated to plasticize the material present in the machine. The screw is then moved axially to establish an annular discharge gap 16 through which the plasticized material is fed to the mould 7, 8. When the mould is filled the resulting pressure reaction causes movement of the screw 2 to the right until the contact disc 18 actuates the switch 22 which causes stopping of the rotation of the screw 2 and, through the hydraulic jack 11, 12, the screw 2 is returned to its starting position so as to supply additional material under pressure into the mould to compensate for the shrinkage of the material in the mould during the cooling.
