Abstract:
An apparatus for injection molding a liquid into a plurality of cells in a plate for solidification therein comprising:an injection head having a bottom surface including a vacuum slot and an injection slot spaced axially therefrom;means for joining together in abutting contact and effecting relative axial sliding movement between said injection head and said plate for sequentially joining in flow communication each of said cells with said vacuum slot and said injection slot in turn;means for evacuating gas from said vacuum slot for effecting a vacuum in said cells in turn during said relative axial sliding between said injection head and said mold plate;means for supplying said liquid into said injection slot to fill said evacuated cells in turn; andmeans for linking in flow communication said vacuum slot and said injection slot so that surface tension of said liquid prevents evacuation of said liquid injected into said cells while allowing evacuation only of said gas therefrom.
