摘要： A sand molding machine has two compacting chambers angularly spaced from one another about a horizontal axis. The chambers are pivotally mounted for oscillation about a horizontal compacting axis after each sand molding operation. Each chamber is angularly movable 90* from an upper sand filling and compacting position to another lateral side of the axis where the molds are ejected. Two compacting rams, each having two arms disposed at 90* to one another, are pivotally mounted within respective yokes which are mounted for reciprocation along the compacting axis. Each compacting ram, one on each side of a chamber in the compacting position, oscillates 90* about a vertical axis to bring one of two sand compacting patterns into alignment with an open side of the compacting chamber. The oscillations of the compacting rams and of the compacting chambers are synchronized to insure that each sand compacting pattern is associated with a different one of the compacting chambers. By alternately forming the sprue holes 180* out of phase relative to one another, it is assured that the sprue holes of the molds which are ejected on each lateral side of the compacting axis are at the upper surfaces thereof. Ejector members are reciprocally movable along ejecting platforms. A roller is fixed on the platforms for causing the ejector members to turn from initially vertical to inclined planes to facilitate insertion of cores into a core supporting member when the ejector members are withdrawn from a compacting chamber. A spring and a stop are provided which reset the ejector members to their vertical planes when the ejector members are advanced into the compacting chambers.

摘要： A molding apparatus with a closed loop conveyor mounted on a conveyor frame consisting of a plurality of consecutively connected pattern-carrying carts wherein tandem compacting rollers are provided above the conveyor for consecutively compacting at different compacting pressures mold material deposited in flasks positioned on each of the moving patterncarrying carts. Additional mold material may be supplied to the moving carts at a point between the compacting rollers. Removal of the flasks from the pattern-carrying carts is provided for on the underneath or bottom portion of the conveyor. There, means are provided with each cart to permit the downward drawing of the flask, previously temporarily secured and retained to the cart in the form of clamping yokes, away from the cart in aligned relation to a lowered position below the level of the cart during which the flask is supported by the clamping yokes. Means to release the drawing means is provided to operate as each cart commences its travel along the conveyor bottom portion. Means may further be provided to control the rate of downward descent of the flask during the drawing operation.

摘要： A flaskless molding machine is disclosed for producing continuous stacks of molds. The machine comprises four operating stations disposed on ninety degree spacing about its periphery. Two oppositely disposed stations are mold forming stations and the alternate two stations are the receiving ends of oppositely spaced mold decks upon which the completed molds are stacked. A body containing four mold forming chambers oscillates between two positions to place the respective chambers alternately in alignment with the mold forming stations and the ends of the mold decks where the operations are performed.

摘要： An apparatus for producing foundry moulds comprising a machine frame, a flask turntable and a pattern turntable vertically journaled on the machine frame. A flask rests on the flask turntable, and a pattern depends from the pattern turntable. The apparatus is provided with means for placing sand in the flask and has means for rotating the flask turntable and the pattern turntable to position the pattern above the flask. The apparatus also has means for pressing the pattern into the sand while confining the sand to the compartment.

摘要： A machine for producing casting moulds comprises a multilink chain, each link being a flat plate which carries a moulding box. The chain is circulated to carry empty moulding boxes beneath a sand filling device followed by a compacting device and filled and patterned moulding boxes are eventually removed from the chain and stacked on a lifting platform.

摘要： This disclosure relates to molding machines. The molding machine forms a mold by squeezing a molding medium located in the molding chamber between the vertically spaced pattern plate which cover the upper and lower ends of the molding chamber. After mold formation the upper pattern plate is removed and the molding chamber together with the bottom pattern plate are tilted to a horizontal orientation. The mold is pushed out of the flask onto a pouring conveyor.

摘要： A molding machine in which a pressure plate and a support plate for a mold box are movable toward each other for compacting molding sand in a mold box placed upon the support plate comprises a pressure plate composed of two complementary parts. These plate parts can be selectively moved either into an engaged position in which they form a continuous pressure plate or into a spaced-apart position. In the latter position the two plate parts open a discharge for feeding molding sand into the box through a feed duct in a housing part of the machine.
