Abstract

1306697 Injection nozzle K AOKI 5 June 1970 [7 June 1969 29 Dec 1969] 2752/70 Heading B5A An injection nozzle 2, heated by heater 20 and engaged during injection with an inlet bushing 24 of a mould 5, includes a through passageway 3 within which a closure rod 4 is longitudinally reciprocable from an open position (shown in Fig. 1) to a closure position (shown in Fig. 2) in which the rod projects through the end of the nozzle and engages the inner surface 7 of the bushing. The rod is reciprocated by a lever 14, pivoted at one end to a slide 9 which is located in a housing 11 which projects into the passageway 3 and to which the rear end of the member is fixed. The lever is pivoted at its other end to the piston-rod 17 of a piston-andcylinder mechanism 16, 19 mounted upon the nozzle housing between plates 23. When the rod 4 is in its closure position, its flat front face is level with the inner surface of the mould cavity thereby eliminating any sprue. In a second embodiment the member may stop short of the mould surface thus allowing a sprue of reduced length to be formed.
