Abstract: A process for producing multipiece complementary tooling castings is disclosed in which hollow internal surfaces are cast in a mold having a soft, low strength sand core piece to define such hollow portions and external surfaces are cast against hard, resin-bonded sand mold surfaces. The castings are removed from their respective molds while still warm and nested and pressed together to bring their working surfaces into conformance with each other. The result of this practice is a set of tool pieces that require little machining and display high accuracy in their as-cast condition.

Abstract: A cope flask is precisely centered relative to a cope pattern by a flask displacement mechanism affixed to a cope stool which lineraly shifts the flask relative to the pattern while taking up clearance between the locator pins of the cope flask and the locator bushing in the stool. This precision centering is maintained while mold sand is poured into the flask and compacted. The cope mold comprising the flask and the hardened sand is stripped from the stool for subsequent mating with a drag mold made in a similar manner but with the drag stool having locator pins secured in its top surface and the locator bushings provided in the drag flask. As with the cope mold making procedure, the drag flask is precisely centered relative to the drag pattern by linearly moving the drag flask to take up clearance between the centering pins and the centering bushings in the drag with the displacement mechanism.

Abstract: A register system is provided for making molds for metal casting which reduces flaws attributable to parting line shift. This is accomplished by urging the cope mold flask (11) against two fixed stops (50, 52) on the long axis, and one fixed stop (54) on the short axis of the flask. This same register principle is applied in the drag mold making station 18, where the drag flask (15) is urged against two fixed stops (86, 88) on the long axis, and one fixed stop (90) on the short axis of the flask.

Abstract: For the production of horizontally divided flaskless foundry molds a mold making plant is employed consisting of a vacuum mold blowing machine, joined with a casting and cooling line and a shake out station. The vacuum mold blowing machine is provide with a pattern plate swapping device and designed in the form of a single station mold making maching, in which drags and copes of a mold are produced alternately. The single mold flask is part of the mold making machine and has means for stripping it from a drag or cope before removal of the same from the machine. This makes it possible to have one core insertion station with space for a plurality of drag without having more than one machine flask.

Abstract: A register system is provided for making molds for metal casting which reduces flaws attributable to parting line shift. This is accomplished by urging the cope mold flask (11) against two fixed stops (50, 52) on the long axis, and one fixed stop (54) on the short axis of the flask. This same register principle is applied in the drag mold making station 18, where the drag flask (15) is urged against two fixed stops (100, 102) on the long axis, and one fixed stop (90) on the short axis of the flask. At the closer station (24), where the mold halves are assembled, they are again urged against two fixed stops (134, 136) on the long axis, and one fixed stop (142) on the short axis of the flasks. Thus the flasks are properly aligned to the patterns at the mold making stations, and again properly aligned to each other at the closer station, so as to eliminate parting line shift problems of the mold halves.

Abstract: A mold handler for flaskless foundry molds made up basically of a horizontal support beam and two clamping arms supported for movement along the beam toward and away from each other. Each clamping arm has rotationally mounted pads with gripping surfaces having serrations thereon. The pads are self-aligning. The clamping arms move via a fluid circuit operably connected thereto. The entire structure is suspended by apparatus lying substantially within a plane containing the center of gravity of the beam and the structure it supports. The clamping arms are maintained at equal and opposite distances from the center of gravity at all times during operation of the mold handler by means of an interconnecting synchronizing linage. The fluid circuit controls and actuates fluid cylinders to urge the clamping arms toward and away from one another selectively to engage and release the gripping surfaces with and from a flaskless mold positioned therebetween.
