Abstract: An injection molding apparatus includes: a first mounting block configured such that a fixed mold is able to be mounted thereon; a second mounting block configured such that a movable mold facing the fixed mold is able to be mounted thereon, provided with a first through hole through which a first diver is inserted, and configured to move back and forth with respect to the first mounting block along the first diver; and an injection unit configured to inject a molten material into a cavity defined by the fixed mold and the movable mold. In a state where the movable mold is mounted on the second mounting block, the second mounting block includes, between the movable mold and the first through hole, a heat conduction prevention portion configured to prevent conduction of heat from the movable mold.

Abstract: A plasticizing device includes a driving motor, a rotor rotated around a rotation axis by the driving motor and having a groove forming surface on which a groove is formed, a barrel having an opposed surface opposed to the groove forming surface, a communication hole into which a plasticized material flows being provided in the barrel, a housing section housing the rotor, a first restricting section fixed to the rotor and having a first contact surface facing the barrel side, and a second restricting section fixed to the housing section, opposed to the first contact surface, and having a second contact surface contactable with the first contact surface. Movement of the rotor along the rotation axis is restricted by the first restricting section and the second restricting section. The groove forming surface is separated from the opposed surface at a predetermined interval in a state in which the first contact surface and the second contact surface are in contact.

Abstract: A plasticizing device that plasticizes at least a part of a material to generate a plasticized material, the plasticizing device includes: a drive motor; a screw configured to rotate around a rotation axis by a drive force of the drive motor and having a groove forming surface in which a groove is formed; a speed reducer disposed between the drive motor and the screw and configured to transmit the drive force of the drive motor to the screw; a barrel having a facing surface facing the groove forming surface and having a through hole into which the plasticized material flows; a first heater configured to heat the material supplied between the screw and the barrel; a first cooling unit configured to cool the drive motor; and a heat insulating unit disposed between the first cooling unit and the speed reducer. At least a part of the heat insulating unit overlaps the first cooling unit when viewed along the rotation axis of the screw.
