Abstract
An injection compression molding device includes a first mold configured to compress a molding resin, a second mold facing the first mold, and a height adjustment device located inside the second mold, the height adjustment device including an inclined surface having an outer surface opened in a direction in which the first mold is separated from the second mold, where at least a part of the height adjustment device is selectively joined to the first mold to form a cavity located between the first mold, an upper surface of the second mold, and the height adjustment device.
Claims18
An injection compression molding device comprising:
- a first mold configured to compress a molding resin;
- a second mold facing the first mold;
- and
- a height adjustment device located inside the second mold, the height adjustment device configured to open in a direction in which the first mold is separated from the second mold,
- wherein at least a part of the height adjustment device is selectively joined to the first mold so as to form a cavity located between the first mold, the second mold, and the height adjustment device.
An injection compression molding method comprising:
- moving, by a controller, a guide block upwards along an inclined surface of a second mold by introducing gas in a direction in which the first mold is separated from the second mold;
- moving, by the controller, the first mold in a direction facing the guide block such that a surface of the first mold and a surface of the guide block contact each other;
- injecting, by the controller, a molding resin into a cavity formed between the first mold, the second mold, and the guide block;
- compressing, by the controller, the molding resin injected into the cavity by the first mold;
- and
- moving, by the controller, the first mold in a direction away from the second mold, cooling a product, and extracting the product.
A non-transitory computer readable medium containing program instructions executed by a processor, the computer readable medium comprising:
- program instructions that move a guide block upwards along an inclined surface of a second mold by introducing gas in a direction in which the first mold is separated from the second mold;
- program instructions that move the first mold in a direction facing the guide block such that a surface of the first mold and a surface of the guide block contact each other;
- program instructions that inject a molding resin into a cavity formed between the first mold, the second mold, and the guide block;
- program instructions that compress the molding resin injected into the cavity by the first mold;
- and
- program instructions that move the first mold in a direction away from the second mold, cooling a product, and extracting the product.
