Abstract

929,105. Injection moulding machines. DOWDING & DOLL Ltd. April 16, 1962 [May 8, 1961], No. 16681/61. Class 87(2). [Also in Group XXIV] In an injection moulding machine having a mould 8, 9 which is held closed by a toggle 13, 14 in its fully extended dead centre position, and wherein movement of the toggle 13, 14 is controlled by a crank 23 connected to one link of the toggle by a connecting rod 25, the crank 23 is just past dead centre position when the toggle 13, 14 is extended and is prevented by a stop 28 from further rotation. The crank 23 may be rotated by a handle 29 or by a motor (not shown). The mould parts 8, 9 are attached to fixed and movable platens 7 and 10 respectively.
