Description

Technical Field

[0001] The utility model relates to the technical field of machine tool bed casting, in particular to a demoulding structure of a machine tool bed casting mold. Background Art

[0002] Demolding the machine tool bed casting mold is a key production step that affects the quality of the final casting. In the demolding step, the operator wears appropriate protective equipment, such as gloves, goggles and protective clothing. Then the staff uses tools to gently tap the various parts of the mold to gradually remove the casting from the mold, and finally remove the casting from the mold. During the entire process, due to the high cost of metal molds, they are generally reused many times, and high-temperature molten metal is injected into the mold under high pressure, which will cause the mold to be slightly deformed after repeated use. In the case of high-pressure injection, the molten metal may be forcefully squeezed out of the slightly deformed joints of the mold to form sharper flash. Due to the large size of the machine tool bed, the staff may be cut by the flash if they are not careful during the demolding process.

[0003] Based on this, the utility model designs a demoulding structure of a machine tool bed casting mold to solve the above problems. Utility Model Content

[0025] The bottom plate 2 is fixedly connected with an electric slide rail 7, and a plate mold 8 is slidably connected to the electric slide rail 7. A cover plate for easy access can be provided on the plate mold 8. A fixed block 9 is slidably connected to the middle of the plate mold 8, and two groups of vibration plates 10 are symmetrically fixedly connected to the fixed block 9. Each group of vibration plates 10 is located on a groove opened for it by the plate mold 8;

[0026] The lower end of the fixed block 9 is fixedly connected to a first magnet 11, a second magnet 12 is arranged below the first magnet 11, and an iron rod 13 is fixedly connected to the lower surface of the second magnet 12; the lower end of the iron rod 13 is slidably connected to a sliding block 14, and the sliding block 14 is slidably connected to the inside of the bottom plate 2, and a U-shaped magnet 20 is arranged on the side of the iron rod 13, and the U-shaped magnet 20 is fixedly installed in the bottom plate 2, a first spring 15 is fixedly connected to the sliding block 14, and driving devices are arranged on both sides of the sliding block 14.

[0027] As a further solution of the utility model, the driving device includes two groups of symmetrically arranged first wedge blocks 16, each of which is fixedly connected to a return spring 17, and each of which is fixedly connected to a connecting rod 18 on a side away from each other. The connecting rod 18 is slidably connected in the bottom plate 2, and a second wedge block 19 is fixedly connected to the upper end of the connecting rod 18. The side of the second wedge block 19 is provided with a support block 21 for driving it to move upward. The support block 21 is slidably connected to the plate mold 8.

[0028] As a further solution of the present invention, the upper surface of the vibration plate 10 and the upper surface of the plate mold 8 are on the same horizontal plane.

[0029] As a further solution of the utility model, a coil is fixedly connected to the iron rod 13, and the coil is connected to the power storage block.

[0030] As a further solution of the utility model, the bottom plate 2 is hollow inside; a cylindrical column adapted to the iron rod 13 is fixedly connected to the upper surface of the sliding block 14, the iron rod 13 is located on the cylindrical column, and the height of the cylindrical column is greater than the distance between the second magnet 12 and the first magnet 11.

[0031] Working principle: start the sliding plate 3 to move downward to a suitable position, open the liquid outlet pipe 6 to inject molten metal onto the plate mold 8, wait for it to cool automatically, or cool down and shape it through external cooling equipment; after the plate mold 8 is cooled and shaped, start the electric slide rail 7 to drive the plate mold 8 to move towards the second wedge block 19;

[0032] In the process of the plate mold 8 moving toward the direction close to the second wedge block 19, when the first magnet 11 on the plate mold 8 moves to the top of the second magnet 12, the first magnet 11 attracts the second magnet 12, so that the second magnet 12 is adsorbed on the first magnet 11 (the iron rod 13, the coil, the power storage block and the fixed block 9 form a closed loop), so that the iron rod 13 moves along with the plate mold 8 toward the direction close to the second wedge block 19;

[0033] When the iron rod 13 moves to the opening of the U-shaped magnet 20, the iron rod 13 continues to move and cuts the magnetic flux lines of the U-shaped magnet 20. Since the iron rod 13, the coil, the power storage block and the fixed block 9 form a closed loop, according to the principle of magnetoelectricity, the iron rod 13 continues to move and cuts the magnetic flux lines of the U-shaped magnet 20 to generate current. After the fixed block 9 is energized, it will vibrate and knock the middle part of the casting on the plate mold 8, so that the middle part of the casting is separated from the plate mold 8 under the vibration and knocking of the fixed block 9. After the fixed block 9 vibrates, it drives the vibrating plate 10 to vibrate. After the vibrating plate 10 vibrates, it knocks the four corners of the casting on the plate mold 8, so that the four corners of the casting are separated from the plate mold 8 under the vibration and knocking of the fixed block 9, thereby achieving the complete separation of the casting from the plate mold 8, and there is no need for the staff to wear protective clothing to manually knock it off; the safety of the staff is protected;

[0034] When the iron rod 13 is about to move to the U-shaped portion of the U-shaped magnet 20, (eg Figure 2 As shown in the figure, the sliding block 14 slides to the end of the slide groove opened for it in the bottom plate 2, and the sliding block 14 stops moving. Since the iron rod 13 is connected to the sliding block 14 by sliding in the up and down directions, the iron rod 13 also stops moving. At this time, the plate mold 8 that continues to move drives the first magnet 11 to continue to move, and the first magnet 11 is separated from the second magnet 12; the stretched first spring 15 returns to its initial position after no force is applied, and the first spring 15 drives the sliding block 14 to return to its initial position. When the sliding block 14 is about to return to its initial position, the sliding block 14 drives the first wedge block 16 to move outward, the first wedge block 16 drives the connecting rod 18 to move outward, the connecting rod 18 drives the second wedge block 19 to extend outward from the bottom plate 2, and when the support block 21 on the plate mold 8 moves to contact with the second wedge block 19, the second wedge block 19 drives the support block 21 to move upward, and the support block 21 lifts the casting on the plate mold 8 upward, making it convenient for external manipulators and other equipment to take out the casting without the need for staff to take it out manually. Since the machine tool bed casting is large, it is further guaranteed that the staff will not be accidentally injured.
