An injection molding system including an injection nozzle that injects resin into a mold and a conveying device that conveys the injection nozzle between a first position where the injection nozzle injects resin into a first mold and a second position where the injection nozzle injects resin into a second mold.

A melt dispenser for plastic molding comprises a barrel unit removably mountable to a drive unit. A feed screw is received within a barrel of the barrel unit and is rotated by the drive unit to dispense molten molding material through an outlet of the barrel. A coupling mechanism can be engaged to hold the barrel unit against the drive unit and on to connect the screw to the drive. The coupling mechanism is operable by an actuator.

A mold-clamping machine includes a pressure receiving mount, a turn table mounted on the pressure receiving mount so as to be freely turnable, a movable mount placed at a position higher than the turn table, tie bars attached to and extending downwardly from the movable mount, and which pass completely through the pressure receiving mount and a traction mount. The mold-clamping machine clamps a metal mold by moving down the traction mount with reference to the pressure receiving mount. Each of the tie bars is freely movable up and down by each of first to third cylindrical guides provided at the pressure receiving mount. The second cylindrical guide and the third cylindrical guide each include a rectangular flange portion fastened to the pressure receiving mount, and respective attachment attitudes of the second cylindrical guide and the third cylindrical guide are adjustable.

What is presented is a mold support structure in a single dual injection molding machine for plastic part formation having at least two injection units. The mold support structure comprises at least one pair of platens located on opposite sides. Each pair of platens is separated by a plurality of reinforcement structures that provide support in the direction in which clamp and injection pressure is applied to the pair of platens during plastic part formation.

An injection molding apparatus comprises a support base and a mold carrier removably mounted to the support base. The mold carrier includes a mounting plate with attachment features for engaging the support base. A mold with two mold plates is slidably mounted to the mounting plate. A clamp is operable to move the plates between open and closed positions. In the closed position, the plates abut one another. In the open position, the plates are spaced apart for removing molded articles.

The present invention relates to a column-free closing unit for an injection-moulding apparatus, wherein a fixed platen (5) is provided, and this platen is arranged on a first wing (3), wherein the fixed platen (5) is fixed to the first wing (3) at a fastening region (9), wherein a closing device (6) is provided, and this closing device acts on a second wing (4) and is connected to a movable platen (7), wherein the closing device (6) is designed to exert a pressing force in the direction of the fixed platen (5), wherein the fixed platen (5) is supported beneath the fastening region (9) via a supporting device, wherein the supporting device comprises a connecting bar (10), which run substantially orthogonally in relation to the longitudinal axis (8) of the machine, wherein the supporting device comprises at least one spring bar (11), wherein the spring bar (11) is designed to transmit the pressing force from the fixed platen (5) to the connecting bar (10), wherein the spring bar (11) runs substantially orthogonally in relation to the longitudinal axis (8) of the machine and in relation to the connecting bar (10).

Extractor systems for extracting a flexible article of manufacture from a mold include an extraction roller, at least one track configured to support the extraction roller, and a trolley configured to carry the extraction roller from a first side of the mold toward a second, opposite side of the mold. Molding systems include a mold and an extractor system. Methods of extracting a flexible article of manufacture from a mold include separating a first platen and a second platen, positioning an extraction roller between the separated first and second platens, engaging the article of manufacture with a row of teeth positioned along the extraction roller, and rotating the extraction roller to wrap the article of manufacture about the extraction roller.

An injection molding machine is equipped with a screw having a spline shaft formed with a spline on an outer circumferential surface, a bush having a spline hole formed with a spline on an inner circumferential surface, a linear motion motor for moving the bush in an axial direction of the screw, a rotational motion motor for rotating the bush about an axis of the screw, and a motor control unit which, in the case of fitting the spline shaft in the spline hole, controls the linear motion motor to advance the bush in a direction approaching the screw in a state that the bush and the screw are separated, and which controls the rotational motion motor to rotate the bush when the acquired output torque becomes equal to or larger than a first predetermined torque.

A rotary platen, which is disposed to face a mold platen, which is provided to be rotatable with respect to the mold platen, and to which a mold is attachable. A plate-form member is attached to a surface of the rotary plate that faces the mold platen. A contour shape of the plate-form member is non-circular.

An injection molding machine includes, on a machine base, a mold having a stationary platen, an injection unit having a nozzle for injecting a molten material into the mold, a nozzle touch mechanism for pressing the nozzle against the mold, and a connecting member for connecting the nozzle touch mechanism and the stationary platen. The connecting member has a support base and an arm part, and also has a first connecting part to be connected to the nozzle touch mechanism on the support base, and a second connecting part to be connected to the stationary platen on an upper part of the arm part. The injection molding machine is configured so that a nozzle touch force is transmitted to the nozzle touch mechanism via the stationary platen and the connecting member. The second connecting part of the connecting member is disposed to be rotatable in a direction along a moving direction of the injection unit.
