摘要： A mold includes: a fixed mold; a movable mold facing the fixed mold; a first plate having a first opening into which the fixed mold is incorporated and fixing the fixed mold; and a second plate having a second opening into which the movable mold is incorporated and fixing the movable mold. The fixed mold and the movable mold define a cavity. The fixed mold and the movable mold are sized for attachment to a first injection molding device, and the first plate and the second plate are sized for attachment to a second injection molding device different from the first injection molding device.

摘要： A material discharge device includes: a drive motor; a screw having a groove formation surface and configured to rotate; a barrel having a facing surface and formed with a communication hole through which a plasticized material flows; a heating unit configured to heat the material; a nozzle from which the material is injected to an outside; and a plurality of measurement units configured to measure a pressure or a temperature of the material. The measurement units are disposed at an outer periphery of a nozzle channel wall, and a thickness of the nozzle channel wall satisfies the following (1) or (2): (1) when the nozzle channel wall is made of a material containing iron as a main component, the thickness of the nozzle channel wall is 0.2 mm or more and 2.5 mm or less; and (2) when the nozzle channel wall is made of a material containing aluminum as a main component, the thickness of the nozzle channel wall is 0.2 mm or more and 4 mm or less.

摘要： A plasticizing device includes: a flat screw that has a groove forming surface on which a spiral first groove is formed, and that rotates; a barrel that has a facing surface facing the groove forming surface and that includes a communication hole through which a plasticizing material flows; a heater that heats resin pellets; and a screw case that accommodates the flat screw and that includes a passage port through which the resin pellets pass toward the flat screw, in which the flat screw has a first side surface on which a first supply port for supplying the resin pellets to the first groove is formed and a second side surface formed on a side farther from the barrel than the first side surface, and a first distance, which is a shortest distance between the first side surface and the screw case, is larger than a second distance, which is a shortest distance between the second side surface and the screw case.
