ABSTRACT:
The mold broadly consists of an upper and lower mold part. The parts define a mold cavity when the mold is in the closed position. A channel is provided in one of the parts, with the channel completely surrounding the cavity. One upper edge of the channel forms at least a portion of the outer edge of the mold cavity. The channel is at least partially filled with an elastomeric material. A shear plate is attached to the other part in a location opposite the channel. When the mold is in the closed position, the shear plate enters the channel, presses against the elastomeric material and presses against the outer edge of the mold cavity. The shear plate is also provided with one or more tapered slots which allow gases to escape from the mold cavity when the mold is in the closed position.
