Patent ID: 7111664

Claim:
A molding device comprising: a lower mold unit having a first molding surface; an upper mold unit located above the lower mold unit and having a second molding surface, the lower and upper mold units being configured to approach and separate from each other, wherein, when the lower and upper mold units approach each other to be closed, a molding cavity is defined between the molding surfaces of the mold units; a storing chamber provided in the lower mold unit, the storing chamber being connected to the molding cavity, wherein molten material is stored in the storing chamber; a pushing mechanism that pushes out the molten material in the storing chamber to the molding cavity in a state where the molding cavity is defined between the lower and upper mold units, wherein the pushing mechanism, including a control means, is adapted to start pushing out the molten material onto the first molding surface of the lower mold unit before the lower and upper units are closed to define the molding cavity; a damper chamber provided in at least one of the lower and upper mold units, the damper chamber being configured to receive an excess amount of the molten material that cannot be accommodated in the molding cavity; and a pressurizing mechanism for pressurizing the excess amount of the molten material in the damper chamber.
