Abstract

1,076,570. Injection moulding machines. R. D. SCHAD. Oct. 30, 1964 [Nov. 1, 1963], No. 44271/64. Addition to 986,273. Heading B5A. In the injection moulding machine described in Specification 986,273, a valve member (47), Fig. 12 (not shown), in the injection nozzle (45) is opened when the pressure in the injection means exceeds a predetermined value. The valve member (47) is operated by a lever (201) pivoted at (200) and biased to closed position by a spring 206 acting through an extension (205) of a piston (203). Opening of the valve is effected by pressure conveyed to the piston (203) through a conduit (211) connected to spaces (140, 141), Fig. 9 (not shown). These spaces constitute a fluid cushion between the injection piston (38) and its constantly rotating crank drive (66a, 65).
