A program controlled machine wherein signals produced in response to execution of programs control operation of machine devices includes a control for storage, retrieval and presentation of audio/video information. The control includes devices for presentation of audio/video information and stored programs including programs for enabling storage of audio/video information files while the machine is in a manual mode of operation and programs for controlling the presentation by the audio/video presentation devices of selected audio/video information from the stored files. The control provides facilities for recording audio/video information and for manually controlled presentation of audio/video information as well as for automatic presentation of audio/video information in response to detection of occurrence of a particular event.

The method of the present invention relates to reducing cycle time in injection molding machines that are running large capacity molds, such as multiple cavity preform molds, and require a high volume supply of quality melt. Specifically, the present invention proposes using a continually plasticizing extruder to supply two melt accumulators which will alternately operate to inject the plastic material into the mold. To accomplish this, a rotary valve at the end of the extruder is controlled to fill the pots, and ball check valves are positioned to control flow direction and limit pressure in certain parts of the system. A shuttle valve between the shot pots and before the nozzle facilitates decompression.

A clamping system for traversing and clamping molds in a molding machine, the clamping system including a toggle-type clamp arrangement defined by a plurality of pivotally connected links. A movable crosshead is carried on a crosshead guide, and a ball screw is non-rotationally secured to the movable crosshead to extend in the direction opposite from the face of a cooperating fixed mold portion. A pair of ball nuts are carried by the ball screw and each of the ball nuts is drivingly connected with a respective servomotor. One of the servomotors is adapted to provide rapid traverse movement for the movable crosshead, and the other servomotor is adapted to provide high torque for high clamping force to hold a pair of mold halves in tightly contacting relationship during the injection into a mold cavity defined by the mold halves of a flowable material under pressure.

A clamping system for traversing and clamping molds in a molding machine, the clamping system including a toggle-type clamp arrangement defined by a plurality of pivotally connected links. A movable crosshead is connected with one end of the toggle and is carried on a crosshead guide, and a ball screw is rotatably secured to the movable crosshead to extend in the direction opposite from the molds and through a stationary platen. A ball nut rotatably carried by the stationary platen is in engagement with the ball screw and is drivingly connected with a first motor to axially move the ball screw to provide between the molds a clamping force sufficient to resist separation of the molds during high pressure injection of molding material. A second motor is drivingly coupled with the ball screw and is movable therewith in an axial direction. The second motor is adapted to rotate the ball screw for rapid traverse movement of the movable crosshead to rapidly bring the molds into and out of contact.
