Provided is an injection device and an injection control method which are capable of preventing a drooping phenomenon from an injection nozzle even during high cycle molding, and capable of appropriately plasticizing and molding a resin having poor thermal stability. An injection device (10) of the disclosure includes: an injection cylinder (30) which accumulates a molding material and has an injection nozzle (33) at the front; an injection plunger (31) which is moved backward in the injection cylinder (30); an injection plunger driving device (50, 150) which moves the injection plunger (31) backward; and an injection controller (60, 160). The injection controller (60, 160) retreats the injection plunger (31) by the injection plunger driving device (50, 150) to perform metering in a plastication metering step of metering the molding material supplied into the injection cylinder (30).

An injection molding machine capable of changing the position of the supply hole of the resin material in a cylinder as appropriate is provided. An injection molding machine according to one aspect of the present disclosure includes: a supply hole through which a resin material is supplied to an inside of a cylinder, the supply hole being formed in a side wall part of the cylinder; and a closing part that, when a torpedo piston moves to a side of an other end part of the cylinder in order to plasticize the resin material, moves together with the torpedo piston and closes the supply hole.

A molding apparatus and method operation for making a molded part are provided. The molding apparatus includes a mold core extending between a generally flat lower surface and an upper surface defining a runner, a fan gate, and a part cavity for forming the molded part. The mold core includes an inner surface defining a plunger cavity extending into the mold core from the upper surface and having a uniform cross-section parallel to the upper surface and open to the gate. A plunger is slidably disposed within the plunger cavity for pulling material from the gate into the plunger cavity. A first pin extends through a first bore in the mold core to move the plunger within the plunger cavity. A hydraulic cylinder interacts with an ejector plate to move the first pin. A second pin also extends through the mold core and is movable perpendicular to the upper surface.

An injection arrangement for a moulding machine includes a moulding compound reservoir and an injection unit. The moulding compound reservoir is configured to provide a plasticized mass and to push out the plasticized mass through a discharge opening, and a connecting device is coupled to the discharge opening of the moulding compound reservoir and a feed opening of the injection unit, and is configured to direct the plasticized mass from the moulding compound reservoir to the injection unit. The connecting device includes an articulated element, and a relative movement between the moulding compound reservoir and the injection unit can be performed with the articulated element.
