Abstract (en)
[origin: DE10236522A1] The hollow shell core(1) houses an internal cooling tube(5) which forms a gap with the inner surface(4) of the core and is coaxial with the latter over its entire length. At the front end there is an outlet(9) for coolant. Cooling grooves(11) on the inner surface of the core run transverse to the central axis of the core. Cooling grooves(11) have a pointed and/or rounded cross-section and form a helical path along the inside of the core. The grooves extend over the surface area of the core on which a plastic molding is injected. The cooling tube outlet(9) has one or more cut-outs(13) extending along the central axis.
