Abstract

1443313 Injection moulds KUNSTOFFWERK Gebr ANGER GmbH & CO 21 Aug 1973 [25 May 1973] 05500/76 Divided out of 1442824 Heading B5A An injection mould core 1 is provided with magnetic holding means 2 ... 5 embedded therein for detachably holding at least one core element 10a ... 10d mounted on the core to define a recess in the moulded article. As shown, a plurality of core elements 10a ... 10d are mounted on the core so as to form a collar which may be used to form an internal annular recess in a moulded pipe or container. The magnetic holding means may comprise at least one electromagnet and/or at least one permanent magnet. The magnets may be received in insulating sleeves 6 ... 9. [GB1443313A]
