Abstract

1,027,065. Injection moulding. VEREINIGTE DEUTSCHE METALLWERKE A.G. March 28, 1963 [April 6, 1962], No. 12401/63. Heading B5A. In an injection mould for making containers 1 provided with tray-supporting ledges or grooves 2 which are formed with abutments or closed at their forward ends, removal of the male mould part 6 from the moulded container is permitted by providing lateral recesses in the part 6 into which ledge-or groove-forming members 8 can be withdrawn by means of draw bars 9. The draw bars 9 are bolted to a plate 5 and each carries a member 10 slidably engaging an oblique groove 7 in the member 8.
