Abstract: This invention relates to an improved seal for injection molding mechanism. The lower nozzle portion of a heater with the reciprocal valve pin extending centrally therethrough extends downwardly to the gate in the mold. The generally cylindrical seal is horizontally located in an outward upward flare of the air space between the lower nozzle portion and the mold. The seal has a V-shaped lower surface which provides inner and outer circumferential lips which prevent the pressurized melt from flowing upward past the seal. The outer wall of the seal extends across the flare of the air space with only a portion of the outer lip abutting on the mold, thus substantially reducing heat loss from the heater through the seal to the cooled mold.

Abstract: Each mold in a battery of molds consists of a female die which has a cylindrical mold cavity which is open on both ends. A coaxial end probe or plug is slidable into and out of one end of the cavity and has a duct therein through which plastic material is injected into the cavity. A coaxial center probe or plug is slidable into and out of the other end of the cavity and has a duct therein through which steam is injected into the cavity to heat the plastic therein. A coaxial crush probe or plug with a bore through which the center probe is slidable is itself slidable toward and away from the end of the cavity adjacent the center probe and closes that end of the cavity. A small vent gap is held open between the female die and the crush probe while the plastic beads are being injected into the cavity to allow air to escape from the cavity. The vent gap is closed after the cavity has been filled with plastic beads.

Abstract: A drilling system and method for use on thin frangible workpieces, such as watch crystals and the like, in which the speed of rotation and pecking motion of the drill are programmed to execute a preset schedule of changes with minimal human intervention.In a preferred embodiment, the drill is mounted over the workpiece, which is pneumatically clamped on the work surface in a shallow water bath. The vertical pecking motion of the drill is under the dual control of a primary cable tensioned by weights on one end under control of a solenoid; and a secondary cable, the tension of which is responsive to the rotation of a master cam. The latter also initiates relay action for sequential operation of controls. The drill operates at an initial, relatively low rotational speed and a brisk pecking motion. At a preselected point near the lower end of the drill hole, the rotational speed of the drill is shifted to "high", and the pecking motion is slowed.

When the core bars with their cores are removed from the mold bars, they are temporarily stored on and carried by the conveyor.

Abstract: A drilling or milling machine has a suction chamber surrounding an axially moveable tool, the chamber being axially moveable relative to the tool and spring biased for abutment against a working surface during machining, after the tool has been fed forwardly in a rapid first phase, then slowly just prior to and during machining. The chamber is composed of two half-shells secured onto a mount on the tool body by a locking ring, and which can be separated by removal of the ring and radial outward movement to provide access to the tool without a need to raise the tool body. The abutment-surface of the chamber may be rigid for laterally-stationary tools, or formed of a ring of flexible bristles for laterally moving tools, e.g. for routing printed circuits. Several compressed-fluid delivery nozzles can be provided in the suction chamber to improve the removal of dust and chippings.

Abstract: This invention relates to an improved valve-gated injection molding mechanism illustrated in a multi-cavity arrangement. A vertical valve pin reciprocates in a central bore in a heater enclosed in the mold actuated by an air operated piston through a rocker arm to precisely control the opening and closing of a gate into a cavity through which pressurized molten plastic material is supplied from a molding machine. A titanium alloy seal is provided in an air space between the heater nozzle and the mold near the gate to reduce the quantity of molten plastic material flowing into the space thereby reducing the creation of cold slugs and problems on color changes. The lower portion of the valve pin is formed of a highly conductive material such as a beryllium-copper alloy to increase heat transfer to the lower tip of the valve pin.
