Abstract
The molding apparatus includes a cavity mold with a cavity surface for defining a cavity in which a molten injection material is injected, and a core mold with a core surface for defining the cavity upon engagement with the cavity mold. The core mold has an intermediate core mold plate having the core surface and a support plate. A guide pin inserted into a guide hole formed in the cavity mold and fitted through the intermediate core mold plate to allow the intermediate core mold plate to be moved only in a forward and backward direction is fixed to the support plate. A first spring is installed between the intermediate core mold plate and the support plate, a first heating means is installed to a parting surface of the intermediate core mold plate and a cooling means is installed to the support plate.
Claims17
An apparatus for injection molding, the apparatus comprising:
- a first mold comprising a first cavity surface;
- a second mold comprising:
- a heating plate comprising a first surface, a second surface facing away from the first surface, and at least one channel arranged in a body of the heating plate between the first and second surfaces, wherein the first surface comprises a second cavity surface opposing the first cavity surface, wherein the first and second cavity surfaces in combination are configured to define a molding cavity together with or without additional surfaces,
- a plurality of heating extensions passing through the at least one channel and configured to generate heat for heating the heating plate, and
- a cooling plate comprising a cooling surface facing the heating plate;
- and
- wherein the heating plate is movable relative to the cooling plate between a first position and a second position, wherein the second surface contacts the cooling surface in the first position whereas the second surface is separated from the cooling surface in the second position.
