摘要：a device for injection mould halves (10) has a mobile and fixed mould (15, 17).one or more valves gas fungus (28) are set in the mobile parts (17) and \\/ or fixed (15). thevalves are located in the fungus (28) to produce a cavity (23) between the movable halfmold (17) and a fixed half mould (15) when the mold halves are closed.at least one gasline is connected to the valves to the fungus (28) and a source of gas pressure to openthe valve is adapted for yeast (28) in response to the injection of molten plastic into theclosed mold halves (15, 17).porous metal covers (72) can be used as an alternative to themushroom valve (28) so that a gas pressure through the lid (72) can be used to carry outthe task of casting.injection moulding is also described, using the gas injection into thehalves of the mold immediately after injection of the liquid plastic (49).
