    摘要: An injection apparatus of the invention injects a molding material supplied from a material supply port, and includes a die, a material supply apparatus that extrudes the molding material that is thread-like or strip-like via the die, and a material guide apparatus that guides the molding material supplied via the die to the material supply port. The material discharge port of the material supply apparatus and the die protrude downward in the material supply apparatus, and a pressure inside the material guide apparatus is reduced by a pressure reducing apparatus from a pressure reducing port provided above the material discharge port of the material supply apparatus and the die.

    摘要: A flow rate adjusting device includes a main body portion having a first opening portion to which a molten material is supplied, a second opening portion from which the molten material is discharged, a supply flow path communicating with the first opening portion and the second opening portion, and a cross hole intersecting the supply flow path; and a shaft-shaped valve portion disposed inside the cross hole. The valve portion has a tip end portion, a rear end portion, and a recessed portion provided between the tip end portion and the rear end portion and communicating with the first opening portion and the second opening portion, and the valve portion is rotated in the cross hole to change a position of the recessed portion, such that a flow path cross-sectional area of the supply flow path is changed to adjust a flow rate of the molten material discharged from the second opening portion; a storage chamber storing a part of the molten material flowing through the supply flow path between the first opening portion and the valve portion is defined by the tip end portion and an inner wall surface of the cross hole; the valve portion has a first contact surface provided between the recessed portion and the rear end portion and facing the rear end portion side; and the main body portion has a second contact surface to come into contact with the first contact surface from the tip end portion side.

    摘要: The present disclosure provides an injection machine for a recycled plastic injection molding system. The injection machine comprises a supplying system configured to drive plastics from an entry end to downstream of receiving route, a heating system disposed to downstream of the supplying system and configured to melt plastics and drive plastics to the downstream of receiving route, and a buffer system disposed to downstream of the heating system and configured to be a receiving state and a supplying state. When the buffer system is in the receiving state, the buffer system is configured to receiving plastics from the heating system. When the buffer system is in the supplying state, the buffer system is configured to drive plastics to downstream of the receiving route.

    摘要: There is provided a plasticizing device including a rotor which rotates around a rotational axis, and has a groove forming surface provided with a groove, a barrel which is opposed to the groove forming surface, and has a communication hole, and a first heating section configured to heat a material fed between the rotor and the barrel, wherein the material fed between the rotor and the barrel is plasticized and discharged from the communication hole due to a rotation of the rotor and heating by the first heating section. In the plasticizing device, the first heating section includes a first portion configured to house a first heat source, includes a second portion which is disposed closer to the groove forming surface than the first portion in an axial direction of the rotational axis, and which has a shape surrounding the communication hole when viewed along the axial direction, and is configured so that heat by the first heat source is transferred to the material between the rotor and the barrel via the second portion.
