摘要： The coatings are for an expendable sand core for die casting dies, which sand core has spaces between its contacting sand grains at least partially filled with resin binder. The first, base, hard, or refractory coating for this core is applied from an aqueous suspension comprising a finely ground refractory of fused silica, a refractory binder, and at least two different compounds selected from the groups of compounds or additives consisting of: (1) a suspension agent, (2) a dispersant, (3) a wetting agent, and (4) an anti-skinning agent. The refractory in the first coating may also include a minor amount, i.e. less than 50%, of another refractory oxide. The amount of binder in the first coating is less than about 15% by weight of the total liquid suspension, and the amount of additives is less than about 1.5% and usually less than 1% by weight of the total liquid suspension. The second, top, soft, or release coating is an organic liquid suspension containing between about 5% and 60% by weight of the whole suspension of particles of a release material selected from the group consisting of anhydrous powdered aluminum, graphite, talc, titanium dioxide, and zircon, and less than about 10% by weight of the total suspension of a resinous binder, less than 15% of at least two additives or different compounds selected from the groups additives and compounds consisting of a suspension agent, a dispersant, and an anti-setting agent.

摘要： The locating pins have notched ends, each of which simultaneously restricts the movement of an expendable core in two orthogonal directions in a die casting die. A plurality of these pins alone and with other pins project into the space between the printout cavity in a die casting die and the printout portion of an expendable core positioned in that cavity. Other pins having flat ends locate the core in only one directional line. Still other pins having tapered ends require special pockets in the printout section of the core, which pockets have sides that must be formed adjacent to the tapered surfaces of these pins. The configurations of the space around the printout portions of the cores permit molten metal injected into the die to produce a skin or skull over the printout portions, which skin can have thicker ribs or portions through it for further reinforcing the printout portions. These printout portions on the parting line between two dies may have restrictions at the junction of the printout portion with the main portion of the core to form break-off rings. These rings and ribs may be formed either in the die or in the printout portion of the core, or both.

摘要： The disclosure concerns a square die-cast elevated floor plate having a top continuous or perforated panel reinforced underneath by a polygonal tessellation grid of ribs. All of the ribs of the grid, including their integral ejector pin bosses, and, if desired, the peripheral ribs or border flange, are of the same depth; however, concentric rows of polygons in the tessellation pattern have their ribs gradually increasing in thickness from the border flange to the center of the plate. The polygons in the pattern may comprise squares and octagons in which alternate sides of the octagons have a ratio of one to the square-root-of-two, and the sides of the squares correspond to the sides having the square-root-of-two length. The continuous or perforated top panel may be formed integrally or adhered to the tessellation rib pattern. The rib pattern with its integral ejector pin bosses is preferably symmetrical for at least 180.degree. rotation of its die. The integral ejector pin bosses are preferably located along the ribs of the octagons so that they align with the ends of slotted perforations in the top panel. The thickness of the perforated floor panel may be greater than that of the continuous top panel. These floor plates may be supported at their adjacent corners by vertically adjustable jacks.

摘要： This disclosure concerns a casting die for a cylinder, including engine blocks having a plurality of cylinders such as for internal combustion engines, including an expendable core for forming a jacket around the cylinders. This core has a printout portion at one end of the cylinder which is held in place by a cooperating flange on a mandrel that fits inside the cylinder. This mandrel may hold a liner for the cylinder. A dowel is provided in one of the die parts for insertion into the hollow mandrel. The mandrel is held in position by being clamped between the two opposing die parts, and the flanges of the core printout portion may be loosely held in the printout cavity of one of the die parts which preferably also contains one or more locating pins for bridging at least part of the gap between the printout portion and the printout cavity in the die for better positioning the core in the die. The core and mandrel may be assembled outside the die before being placed on the dowel, and after the casting is made, the mandrel and core are removed with it and then separated so the mandrel can be reused. For forming plural cylinders in an engine block, a secondary mandrel frame may be employed for further supporting the separate mandrels for each cylinder and the plural cylinder expendable core by holding the flanged printout portion of the core between the flanges on the separate mandrels and the secondary mandrel frame. In casting the plural cylinders of a V-engine block, retractable dowels permit the employment of die parts and slides that move only at right angles to each other.

摘要： A stationary die for a horizontal die casting machine has an oscillatable molten metal injector below the die that oscillates from an acute angle outside the die for filling with molten metal to an acute angle under the die or injecting the molten metal into the die. The stationary die has an annular docking block at the same acute angle to the horizontal as the axis of the shot sleeve under the die. The edge of the aperture at the outer end of the docking block is adjacent to and substantially in the plane of the parting surface of the stationary die so that the docking block per se projects outwardly from the surface. Correspondingly, the adjacent parting surface of the movable die is provided with a cavity for fitting this projection of the docking block, but since the surfaces of this docking block are at convergent acute angles, they provide no restriction to the movement of the movable die. A trough duct is provided in the stationary die from the open end aperture of the docking block to the die cavity for the molten metal for producing the casting between the closed dies. Ejector pins are provided for removal of the casting after it has been cast and the dies parted. Furthermore, the movable die may be provided with one or more slides, including a slide adjacent the docking block with a cavity therein for receiving the outward projecting part of this block from the surface of the stationary die.

摘要： A horizontally movable die has a bottom slide and cooperates with a stationary die in a die casting machine, which machine has a vertical injector for molten metal mounted underneath the dies and oscillatable to an acute angle to the vertical from under the dies for filling with molten metal. The outwardly movable shot sleeve of the injector seats in two semi-annular docking blocks, one mounted in the stationary die and the other mounted on an outward projection or extended portion of the slide on the movable die. Thus, when the dies are closed, the two semi-annular docking blocks for the shot sleeve form an aperture completely within the stationary die, which aperture communicates with an outwardly tapered trough duct that extends to the casting between the dies. This trough configuration forms a sprue in the stationary die that permits the separation of the movable die from the stationary die and then the retraction of the bottom slide without obstruction by any part of the sprue or the casting. This configuration also enables the vertical injector's shot sleeve to be injected between the stationary die and a bottom slide on the movable die. Additional slides may be employed on the movable die, and ejector pins are preferably provided in the movable die for ejecting the casting after the dies and slides have been retracted.
