Patent ID: 7575427

Claim:
A mold for foam molding, comprising: a plurality of gas-blowing units for removing a molding from the mold by pneumatically pushing the molding and gas flow-restricting units, wherein the gas-blowing units include gas channels extending to the cavity and valve elements which block the gas channels during molding and which are moved into the cavity during demolding in such a manner that the valve elements are pneumatically pushed by gas supplied to the gas channels, the gas channels are supplied with gas from a common gas supply source, and the gas flow-restricting units allow the gas to flow into the gas channels after the valve elements block the gas channels and restrict the gas to flow into the gas channels after the valve elements protrude, wherein the gas flow-restricting units allow the flow of the gas to be continued although the gas flow-restricting units reduce the amount of the gas flowing into the gas channels after the valve elements protrude, and wherein the gas flow-restricting units are connected to the valve elements, include gas flow-restricting valves moving together with the valve elements and the gas flow-restricting valves have openings or notches for allowing the gas to flow into the gas channels.
