Abstract (en)
[origin: EP0933153A1] At least one additional gas inlet channel (34) and one or more additional gas outlet channels (36) are formed between the mold cover core (14) and pressure plug shield (16). A cover (22) is provided inside the pressure plug (24, 26) beneath these additional gas channels, covering the mold cover core and dividing the cavity into top and bottom regions, between which gas can flow. The mold includes a cover core linked to supply lines for pressure-generating gases. A pressure plug shield is placed on top of the cover core to seal off the pressurized gas supply region. The cover core is gas-impermeable in the region where it meets the pressure plug shield.
