| An apparatus and method for pressure casting a battery part wherein the state of molten lead is monitored so that when the molten lead enters a liquid-to-solid transformation stage, the volume of the mold available for the lead to solidify therein is quickly reduced through a volume contraction step to thereby cause the molten lead to flow into the remaining volume at the same time one maintains pressure on the molten lead. As the molten lead solidifies under the reduced volume and high pressure it produces a battery part that is substantially free of both tears and cracks. In an alternate method, the lead is allowed to solidify and at least a portion of the lead is mechanically deformed through a volume contraction step to cause cracks or tears in the battery part to be eliminated thereby providing a battery part free of cracks or tears. In another method of forming a pressure cast battery part free of cracks a molten lead under pressure is flowed into a battery part cavity and the pressure of the molten lead is increased to sufficiently high pressure so that when the molten lead solidifies it forms a battery part free of cracks and voids. | ||||||

| 132 | Self-centering trim punch | US10032738 | 2001-12-28 | US20020053272A1 | 2002-05-09 | Mark Phlipot |
| Cast metal parts are created for use in making machinery. When these parts are formed, unwanted material remains in the openings of the parts. This material, called flash, must be removed. In the method of the present invention, the cast parts are placed on a platen of a trim press that has multi-part punches attached thereto that are configured to self-align with the openings in the cast part and operative to evenly remove the flash. The invention also relates to a punch that initially breaks through the flash with a stationary punch that removes a majority of the flash inside the opening of the cast part. Next, a moving or self-centering punch self-aligns to the opening in the cast part and operates to remove the remaining flash. The inventive punch may also include a mounting base for attachment of the multi-part punches to the plate or platen of the press. | ||||||

| 139 | Method of producing castings with means to facilitate burr removal | US427305 | 1982-09-29 | US4494297A | 1985-01-22 | Sten Larsson |
| A method is described for producing castings and removing burrs produced during the casting at the parting line of the casting mold and in regions where cores are supported in core-supporting holes formed in the mold. The casting mold is so shaped that a well-defined burr, which includes a substantially uninterrupted flange projecting from the casting, is formed in the region of the casting which solidifies opposite the mold parting line. The mold may also be so shaped that a further well-defined burr, which includes a further substantially uninterrupted flange projecting from the casting, is formed in the region of the casting which solidifies where a core of the casting mold enters a core-supporting hole. After removal of the casting from the mold, the or each flange is removed by a mechanical cutting tool or by gas cutting, preferably by employing an industrial robot to effect relative movement between the flange and the flange-removing means. | ||||||
