Abstract

DC60 (08/03/55) A method for squeezing casting sand contained in a cavity for upper and lower casting, comprising a step for squeezing the casting sand by bringing the upper and lower compression plates closer together and a step for squeezing the casting sand by moving the forming parts of the two flange plates toward each of the upper and lower compression plates. A method for squeezing casting sand contained in a cavity for upper and lower casting, comprising a step for squeezing the casting sand by bringing the upper and lower compression plates closer together and a step for squeezing the casting sand by moving the forming parts of the two flange plates toward each of the upper and lower compression plates.

All rights reserved which will not appear on the advertisement page: 1. A method for squeezing the filling in the upper and lower casting cavities, defined by double-sided plates, upper and lower casting cavities, and upper and lower squeeze plates, comprising a first squeezing step to squeeze the filling in the upper and lower casting cavities by bringing the upper and lower squeeze plates closer to each other, and a second squeezing step to squeeze the filling in the upper and lower casting cavities by moving the shaped portions of the double-sided plates to each side of the upper and lower squeeze plates. 2. A method for squeezing the filling sand in the upper and lower casting cavities, defined by a double-sided plate, an upper and lower casting cavity, and an upper and lower squeeze plate, comprising a first squeeze step to squeeze the filling sand between the upper and lower casting cavities by bringing the upper and lower squeeze plates closer together, and a second squeeze step to squeeze the filling sand between the upper and lower casting cavities by moving the shape-shaping portions of the double-sided plate and the shape-shaping plate to each side of the upper and lower squeeze plates by bringing the upper and lower casting cavities closer together. 3. A method for squeezing the casting sand contained in the upper and lower casting cavities determined by the double-sided sieve plates, the upper and lower casting cavities, and the upper and lower squeeze plates, comprising a first squeezing step to squeeze the casting sand between the upper and lower casting cavities by bringing the upper and lower squeeze plates closer to each other while maintaining a constant distance between the upper and lower casting cavities, and a second squeezing step to squeeze the casting sand in the upper and lower casting cavities by moving the pattern portions of the double-sided sieve plates and the pattern plate to each side of the upper and lower squeeze plates by bringing the upper and lower casting cavities closer to each other. 4. A double-sided plate in a casting assembly for squeezing the filled casting sand, between which the upper and lower castings are defined by the double-sided plate, the upper and lower cavities, and the upper and lower squeeze plates, comprising a forming member arranged on both sides of the double-sided plate, the two sides of which are in contact with the end surfaces of the upper and lower cavities, and means for expansion and contraction arranged at the periphery of the forming member, wherein these means for expansion and contraction can be extended and contracted by compression by the end surfaces of the upper and lower cavities opposite the double-sided plate. 5. A double-sided plate in a casting assembly for squeezing the filled casting sand, between which the upper and lower castings are defined by the double-sided plate, the upper and lower casting cavities, and the upper and lower squeezing plates, comprising a forming member arranged on both sides of the double-sided plate such that the two sides contact the end surfaces of the upper and lower casting cavities, and at least one excitation actuator to cause each form of the forming member to move from the forming member plate, or at least one excitation actuator to cause each forming member plate to move from this forming member. 6. A double-sided plate in a casting assembly for squeezing the filled casting sand, between which the upper and lower castings are defined by the double-sided plate, the upper and lower casting cavities, and the upper and lower squeeze plates, comprising a pattern member arranged on both sides of the double-sided plate such that the two sides contact the end surfaces of the upper and lower casting cavities, and at least one actuator for causing the plane of the pattern member to move towards the upper and lower squeeze plates. 7. A method for squeezing foundry sand, comprising a packing step to pack the upper and lower casting cavities, defined by the double-sided plates of claims 4, 5 and 6, the upper and lower casting cavities, and the upper and lower compression plates, with foundry sand, a first squeezing step to compress the foundry sand in the upper and lower casting cavities by bringing the upper and lower compression plates closer together, and a second squeezing step to compress the foundry sand in the upper and lower casting cavities by causing the molds and/or plates of the molding portions of the double-sided plates to move toward the upper and lower compression plates. 8. Upper and lower casting cavities in a casting assembly for squeezing the casting sand, filled in between the upper and lower casting cavities, defined by two sided plates, the upper and lower casting cavities and the upper and lower squeezing plates, comprising a plurality of pins which contact the two sides of the two sided plates, and means for expansion and contraction to expand and contract the pins by pressing the rivets between the upper and lower casting cavities and the two sides of the two sided plates. 9. A method for squeezing the casting sand contained in the upper and lower casting cavities determined by a double-sided plate, an upper and lower casting cavity, and an upper and lower compression plate, comprising a first squeezing step to compress the casting sand in the upper and lower casting cavities by bringing the upper and lower compression plates closer together, and a second squeezing step to compress the casting sand in the upper and lower casting cavities by moving the forming portions of the double-sided plate and the forming portion plates to the upper and lower compression plates by bringing the upper and lower casting cavities closer together, wherein the upper and lower casting cavities comprise a plurality of pins in contact with both sides of the double-sided plate, and means for expanding and contracting the pins by pressing the pins between the upper and lower cavities and both sides of the double-sided plate. 1. A method for squeezing the casting sand contained in the upper and lower casting cavities determined by a double-sided plate, an upper and lower casting cavity, and an upper and lower compression plate, comprising: The first squeezing step compresses the casting sand between the upper and lower casting cavities by bringing the upper and lower squeezing plates closer together, and the second squeezing step compresses the casting sand between the upper and lower casting cavities by causing the forming portions of the double-sided plate and the forming portion plates to move to each of the upper and lower squeezing plates by bringing the upper and lower casting cavities closer together, wherein the upper and lower casting cavities comprise a plurality of pins contacting both sides of the double-sided plate, and means for expansion and contraction to expand and contract the pins by pressing the pins between the upper and lower casting cavities and both sides of the double-sided plate, and wherein the double-sided plate is a double-sided plate of any one of claims 4, 5 and 6.
