摘要： A shooting pot actuator for an injection molding machine having two plates carrying pusher rods for pushing against injection plungers within the shooting pots. The plates are mounted outside the mold and the clamp unit, and the pushers extend through bores in the stationary platen of the clamp unit to reach the injection plungers. The actuator reduces the cost and complication of mold design and production, and permits simplified adjustment of the injection plunger stroke.

摘要： A failsafe device, or pressure relief mechanism, for a shooting pot actuator in an injection molding machine. The shooting pot actuator has a multiple pusher rods mounted on one, or more, plates. Moving the plate holding the pusher rods depresses the shooting pot injection pistons and injects molten material into a number of mold cavities. To avoid damage to the machine from the pusher rods if an injection piston seizes, a failsafe device is used to mount the pusher rods to the plates. A shearing member is interposed, or sandwiched, between first and second apertures. Typically, the shearing member is a plate that, in normal operating conditions, blocks rearward movement of the pusher rod. However, when a predetermined shear force is applied to the shear plate, the shearing member shears and the pusher rod retracts within the channel, thereby alleviating the pressure. The failsafe device can be paired with a seizure detection system, using a laser beam, that detects piston and valve gate seizure, and provides appropriate notification or control signals.

摘要： The present invention relates to improved gripper bushing assemblies for use with injection molds, molding machines and other devices. In a first embodiment, the gripper bushing assemblies include an elongated flexible gripping sleeve positioned about a column member such as a tiebar. The sleeve is secured to a member such as a moving platen and is used to clamp the platen to the tiebar in a desired location. The gripper bushing assemblies further include one or more spacers intermediate the sleeve and the platen. The spacers engage the sleeve via a mechanical interlock. The sleeve and spacer(s) are capable of accommodating tiebar stretching which may occur as a result of clamping forces being applied to the mold via the platen. In a second embodiment, the spacer(s) are omitted and the gripping sleeve has a male thread which engages a female thread on the platen.

摘要： A friction clamp assembly for securing a mold of an injection molding machine in a closed position includes a column rigidly secured to a moving platen carrying a mold half and a gripper bush assembly for frictionally engaging and locking the column in a desired position. The clamp assembly further includes a clamp piston for clamping the moving platen in a mold closed position. The clamp assembly transmits a clamping force to portions of a moving platen other than end portions via the column so that platen parallelism is maintained during closing, injection and hold pressure portions of a molding cycle while platen bending is substantially avoided.
