Abstract
A plasticizing device includes a passage defining section that is coupled to a hopper which stores a material and that defines a supply passage to which the material is supplied from the hopper, a plasticizing section that includes an introduction portion which communicates with the supply passage, and a screw, and that plasticizes the material supplied from the introduction portion by rotation of the screw to form a molten material, and a material detection section that detects the presence or absence of the material in the supply passage.
Claims10
A plasticizing device, comprising:
- a passage defining section that is coupled to a hopper which stores a material and that defines a supply passage to which the material is supplied from the hopper;
- a plasticizing section that includes an introduction portion which communicates with the supply passage, and a screw, and that plasticizes the material supplied from the introduction portion by rotation of the screw to form a molten material;
- and
- a material detection section that detects the presence or absence of the material in the supply passage.
An injection molding apparatus, comprising:
- a plasticizing device that plasticizes a material to form a molten material;
- and
- a nozzle that injects the molten material supplied from the plasticizing device to a mold, wherein
- the plasticizing device includes
- a passage defining section that is coupled to a hopper which stores the material and that defines a supply passage to which the material is supplied from the hopper,
- a plasticizing section that includes an introduction portion which communicates with the supply passage, and a screw, and that plasticizes the material supplied from the supply passage by rotation of the screw to form the molten material, and
- a material detection section that detects the presence or absence of the material in the supply passage.
A three-dimensional shaping apparatus that shapes a three-dimensional shaped article, comprising:
- a plasticizing device that plasticizes a material to form a molten material;
- and
- a nozzle that ejects the molten material supplied from the plasticizing device to a stage, wherein
- the plasticizing device includes
- a passage defining section that is coupled to a hopper which stores the material and that defines a supply passage to which the material is supplied from the hopper,
- a plasticizing section that includes an introduction portion which communicates with the supply passage, and a screw, and that plasticizes the material supplied from the supply passage by rotation of the screw to form the molten material, and
- a material detection section that detects the presence or absence of the material in the supply passage.
