Patent ID: 6949214

Claim:
A method for injection molding a finished product comprising the steps of: having a cavity plate connected to a mold base in a laterally floating relationship thereto, said cavity plate having a mold cavity disposed therein and an elongated trapezoidal guide groove formed therein; bringing a core plate longitudinally toward said cavity plate, said core plate having a mold core disposed thereon, said mold core being adapted to be inserted longitudinally in said mold cavity in said mold plate, said core plate also having an elongated trapezoidal guide ridge formed thereon which extends downward longer than said mold core, said guide ridge being adapted to engage said guide groove in said cavity plate in an interlocking relationship; engaging said guide ridge on said core plate with said guide groove on said cavity plate in said interlocking relationship prior to ingress of said mold core with said mold cavity to align said cavity plate with said core plate and eliminate the effects of any two-dimensional, lateral movement of said cavity plate; engaging said mold core with said mold cavity to complete a mold; injecting molten material into said mold to form a molded product; and removing said molded product from said apparatus.
