Abstract
A molded article manufacturing apparatus is configured to include a mold clamping device configured to be able to support a die which shapes a sheet-shaped insert member, the die including a fixed die with a gate, and a movable die which is movable relative to the fixed die; an injection device configured to inject a molding material into the die; and boring means configured to form a bore portion, which is continuous with the gate, in the insert member which is inserted into the die that is supported by the mold clamping device.
Claims6
A molded article manufacturing apparatus comprising:
- a mold clamping device configured to be able to support a die which shapes a sheet-shaped insert member, the die including a fixed die with a gate, and a movable die which is movable relative to the fixed die;
- an injection device configured to inject a molding material into the die;
- and
- boring means configured to form a bore portion, which is continuous with the gate, in the insert member which is inserted into the die that is supported by the mold clamping device.
A method of manufacturing a molded article, comprising:
- inserting a sheet-shaped insert member in a die including a fixed die with a gate, and a movable die which is movable relative to the fixed die;
- shaping, by the die, the insert member which is inserted;
- injecting, by an injection device, a molding material into the die;
- and
- boring the insert member by a pressure of the molding material which is injected by the injection device.
A method of manufacturing a molded article, comprising:
- inserting a sheet-shaped insert member into a die including a fixed die with a gate, and a movable die which is movable relative to the fixed die;
- shaping, by the die, the insert member which is inserted;
