초록

A method for position at least one pair of opposing half-molds in a compression mold that has opposing plates that are compressible towards each other. The method includes placing a shim of a curable material between a first one of the plates and at least one of the half-molds. The mold is closed by compressing the plates towards each other to align and fully contact opposed surfaces of the opposing half-molds in an aligned position. Closing the mold also deforms the shim. The shim is cured in the closed mold to retain the half-molds in the aligned posit...

청구항

[ We claim:] [1.] A method of positioning opposing half-molds in a compression mold having frame members secured to opposite plates, the frame members having a plurality of cavities for receiving the opposing half-molds, each opposing half-mold having a top edge, comprising the steps of:positioning shims made of a curable material between the plates and the half-molds;aligning the half-molds with the top edges of the opposing half-molds in contact and in substantially flat and planar alignment with each other in an aligned position to deform the shims by...
