  • Patent number: 8979155
    Abstract: The present invention provides an apparatus for automated vertical placement of a small rod at a predetermined location, where the apparatus includes a parallel pneumatic gripper having a driver mechanism and a double-v shaped interlocking jaw assembly configured to receive, secure, and release a small rod in a substantially vertical position in response to corresponding signals generated by the driver mechanism. The present invention also provides a robotic system for automated gross retrieval and precise placement of a small rod. The present invention further provides a process for automated gross retrieval of at least one small rod and subsequent precise and substantially vertical placement thereof into a platform at a predetermined location and at a predetermined depth.

  • Patent number: 8082972
    Abstract: A process for creating a lost wax tree, including the steps of assembling a wax tree having a wax pattern and a wax runner, using automated equipment to flex either the wax tree or the wax pattern to bring disconnected sections into proximity, heating at least one of the disconnected sections, contacting the disconnected sections and then moving the sections slightly away from one another. A process for casting a part including the steps of creating a lost wax tree and where the wax tree is later covered with a mold material and the wax tree is removed to create a mold, the mold is then used to cast a part similar to the wax pattern. A lost wax tree having a wax tree with a wax pattern and a wax runner, automated equipment for flexing, a heating element, and automated equipment for manipulating disconnected sections.

  • Patent number: 7290584
    Abstract: A wax pattern welding system and method for producing a pool of molten wax on an area of a surface of a wax component is provided. The wax pattern welding system includes a bar of heat conducting material and a heating element. The bar has a raised heating surface, which has a recessed area for retaining molten wax when the raised heating surface contacts the wax component, and a vent structure. The vent structure facilitates confining the pool of molten wax on an area of a surface of the wax component. In another embodiment, the pattern welding system includes an attachable plate of heat conducting material, which has a raised heating surface with a recessed area, and a vent structure. The attachable plate is configured to be fastened to the bar of heat conducting material.

  • Patent number: 7147032
    Abstract: In a process for the assembly of wax trees, a wax runner is placed in a flat position, and a wax pattern is located adjacent to the wax runner. Both the wax pattern and the wax runner are heated and then placed in contact with one another where heated. Then the wax pattern and the wax runner are separated slightly to form a fillet weld between the wax pattern and the wax runner. An apparatus is also provided which, by robotics, brings a multiplicity of wax patterns to a wax runner and which automatically heats both the wax patterns and the wax runner before simultaneously pressing both the wax patterns and the wax runner together. Once a wax tree assembly is completed, a new wax runner replaces the wax runner that has been formed into a wax tree, and additional wax patterns are affixed in the same manner.

  • Patent number: 7124037
    Abstract: Devices, systems, and methods for monitoring the operation of an injection molding machine, for example, a wax injection molding machine, are disclosed. The devices, systems, and methods may be used for injection molding machines having an injection die, a molding medium injection cylinder, and a control cylinder coupled to the injection cylinder, the control cylinder having a fluid supply conduit. Monitoring and/or control are practiced by monitoring the fluid pressure and the flow rate of the fluid in the conduit. This flow rate and pressure are used to calculate the fluid pressure and flow rate of the molding medium injected into the injection die. A data acquisition system may be used to calculate and output the calculated data. The system can be portable and adaptable for use with any type of injection molding machine and for any injection molding medium.

  • Patent number: 6957686
    Abstract: A knife for heating the wax on the surface of a wax runner. The knife as a surface which is recessed in the center of the surface to permit melted wax to flow up into the recessed area and not flow away from the knife. Alternately, conformal heating surface which melts only that portion of the wax runner to which the pattern gate is affixed. Additionally an electrical circuit is provided which includes a heater and a temperature controller to limit the temperature at which wax is melted.

  • Patent number: 6929050
    Abstract: A wax runner is provided having risers along the edge of the surface which is melted to attach the wax gates of wax patterns to the wax runner. The risers prevent the flow of molten wax over the edge of the wax runner. In addition to the risers or separately, at least one locator extends from both ends of the wax runners, the locators are aligned with one another and assure a constant distance between the ends of the wax runner and the wax pattern being affixed to it. The locators further provide a fixed reference point.
