Abstract
The invention relates to a mould, more particularly an injection mould, for the production of half-finished mouldings or parisons, more particularly Apex rings, from work materials on a rubber basis in a mould cavity bounded by at least two mould parts, more particularly by an upper mould or a lower mould and an intermediate plate.
Claims12
A pressure die casting system for producing rubber mouldings and including at least one heated mould section and at least one cooled mould section, said mould sections forming a mould cavity therebetween, the improvement comprising:
- (a) heating means associated with at least one mould section,
- (b) cooling means associated with at least one mould section for exclusively retaining said rubber moulding adhesively attached to said cooled mould section upon separation of said cooled mould section and said heated mould section, said adhesive attachment to said cooled mould section being achieved solely by means of the cooled mould section being maintained at a lower temperature than said heated mould section, and
- (c) ejector means associated with said cooled mould section for removing said rubber moulding therefrom after said separation of said cooled mould section and said heated mould section.
