Patent ID: 7261534

Claim:
A dual use injection molding tool comprising: injection molding tool having a mold cavity and adapted to inject molten thermoplastic material into said mold cavity through both low pressure and high pressure injection molding techniques, said mold cavity adapted to form a bolster having a cover-stock adapted for use in connection with an interior trim component for a vehicle; and a lifter operatively engaged to said injection molding tool and disposed along the periphery of said mold cavity, said lifter adapted to actuate between a retracted, non-functional position for low pressure injection of molten thermoplastic into said mold cavity and an extended, functional position, for high pressure injection of molten thermoplastic into said mold cavity, wherein said molding tool and the cover-stock cooperate to prevent molten thermoplastic from venting along the periphery of said mold cavity when a low pressure injection molding technique is employed and said lifter is actuated in an extended position to prevent molten thermoplastic from venting along the periphery of said mold cavity when a high pressure molding technique is employed.
