    摘要: A molding method and apparatus is shown which utilizes a plasticizing or injection unit in combination with a horizontal booking press having a first or moveable mold platen carrying a first portion of a mold or molds, and a second, or fixable, door platen carrying a second portion of a mold or molds. The door platen swings open and closed on a hinge, and is fixable in its closed position. When the moveable mold platen is in its′ closed position adjacent the fixed position of the door platen, a mold cavity is formed by the first and second portions of the mold or molds, and material is injected into the mold cavity.

    摘要: A leak detector for a plastics injection molding machine comprises a small diameter conduit (20) located adjacent to a potential leak site on or associated with the machine, through which a regulated supply of air is emitted. When the conduit outlet (26) is blocked with leaked molten plastics, a sensor (45) in the conduit instantly detects a change in air flow or back pressure and triggers an alarm (65), and optionally cuts off the machine automatically to avoid damage to machine components and with the object of reducing machine down time. Changes in incoming primary air supply pressure may be detected to provide a fail-safe system. Alternatively, air pressure in the conduit (20) may be below zero, i.e. a vacuum, so that air is sucked into the conduit at its outlet (26). Several potential leak sites may be monitored simulatneously from a single sensor arrangement.

    摘要: An injection molding machine having a system for detecting nozzle leaks including a thermocouple positioned in the tunnel opening of a stationary platen of the machine at a predetermined location relative to the nozzle to sense instantaneous temperature at the location. A controller coupled to the thermocouple receives signals from the thermocouple and activates an alarm when the temperature in the tunnel opening falls outside of a predetermined normal operating temperature range.
