A molding machine has a feed screw arrangement which plasticizes a material and which injects the plasticized material into a mold. The feed screw arrangement includes an input shaft which is mounted in a housing for rotation relative thereto and for axial displacement with and relative to the housing, the input shaft having a splined end portion which extends outwardly of the housing. The housing is mounted on a support for angular displacement about a pivot axis, and a drive is mounted on an auxiliary support for movement with respect to the support for the housing. The drive has an output shaft which has a central opening adapted to matingly receive the splined end portion of the input shaft when coaxial therewith. Relative axial displacement of the two shafts from an extended position in which the splined end portion is matingly received in the central recess to a retracted position in which the shafts are disengaged frees the feed screw arrangement for pivoting about the pivot axis. The support includes a base portion and a reinforcing portion which straddle the housing, and inlet openings for feeding a material into the housing are provided in both the reinforcing portion and the housing, which inlet openings are coaxial with one another and with the pivot axis.

Molding machine

Two halves of a split mold of an injection molding machine are respectively mounted on a stationary plate and a movable plate guided on guide rods projecting from the stationary plate for movement toward and away from the latter. A guide plate, likewise guided on said guide rods, is connected to the movable plate for movement therewith, and a moving arrangement is connected to the guide plate for moving the same and the movable plate connected thereto toward and away from the stationary plate to thus move the mold halves between an open and a closed position. The guide plate includes a clamping arrangement for clamping the guide plate in fixed position on the guide rods and a hydraulically operated arrangement for holding the mold halves in closed position against the force of molding material injected under pressure into complementary cavities in the mold halves.

Injection molding machine with hydraulically operated closure device

An injection molding machine includes a stationary frame having a pair of spaced upright stationary plates which guide rods of a movable frame which includes, at opposite ends of the rods projecting beyond the stationary plates, a pair of movable plates. One of the stationary plates and the movable plate adjacent thereto respectively carry complementary parts of a split injection mold. A unit including a pressure plate fixed to the other stationary plate is arranged on the rods between the other of the stationary plates and the movable plate adjacent thereto. Cylinder and piston arrangement connects the unit and the movable plate adjacent thereto for moving the movable frame relative to the stationary frame and therewith the mold parts between open and closed positions. The unit includes a clamping device for clamping the unit in fixed position onto the rods a hydraulically operated arrangement cooperating with the pressure plate for preventing the mold parts, when in the closed position from opening under the pressure of the material injected thereinto.

Injection molding machine

A machine for treating articles, such as containers, for example, includes an infeed worm conveyor to receive a continuous flow of containers. The speed of machine operation is regulated by a speed control mechanism so as to maintain a desired constant length accumulation of containers ahead of the infeed worm conveyor. The infeed worm conveyor is axially shiftable, under the influence of forces created by accumulated containers, to transmit such forces to the speed control mechanism as an indication of the size of container accumulation.
