Abstract

1,254,530. Injection moulding. MASCHINENFABRIK UND GIESSEREI NETSTAL A.G. 17 Dec., 1968 [28 May, 1968], No. 60046/68. Heading B5A. An injection mould for hollow articles, such as cups, includes a core 2 and a mould shell 1 providing a cavity therebetween to produce an article with a recessed base part 3b joined to a rim part 3c by an inclined annular part 3a, the thickness of the latter being less than that of an outer annular wall 3d. The part 3b is injected centrally by a passage in the shell, and the pressure of the injected material flowing to the various parts of the cavity effects an automatic centring of the core. Reference has been directed by the Comptroller to Specification 1,101,007.
