[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] Reference Figures 1-3This utility model provides an embodiment of a core box for easy cleaning of residue, comprising a box body 1, a cleaning component 2 disposed on one side of the top of the box body 1, the cleaning component 2 using a combination of tapping vibration and air jet to clean the core box, the cleaning component 2 including a hammer body 22, the bottom end of the hammer body 22 contacting the upper surface of the box body 1, a fixing rod A21 hinged to one side of the surface of the hammer body 22, the fixing rod A21 being fixedly connected to the top of the box body 1, the hammer body 22 tapping and vibrating the upper surface of the box body 1 with its arc-shaped bottom surface, causing the residue in the mold 3 to loosen and fall off, and the core box to be fixed. Rod A21 provides stable support for hammer 22 on box 1. A fixed rod B23 is hinged to the other side of hammer 22. A sliding groove is provided on one side of the top of box 1. Fixed rod B23 passes through and is slidably connected to the inner wall of box 1. A shaft 24 is rotatably connected to the bottom of fixed rod B23. Shaft 24 moves in a circular motion driven by rotating disk 26, thereby driving fixed rod B23 to reciprocate, causing hammer 22 to continuously strike the upper surface of box 1 to achieve a vibration effect. A fixed rod C25 is hinged to the surface of shaft 24, and shaft 24 is located away from the fixed rod. One end of B23 is fixedly connected to a rotating disk 26. A motor 27 is fixedly connected to the inner wall of the box 1. The output shaft of the motor 27 is fixedly connected to the rotation center shaft of the rotating disk 26. The motor 27 provides power for the rotation of the rotating disk 26. The rotation of the rotating disk 26 drives the fixed rod C25 on the shaft 24 to reciprocate around the center. A jet nozzle 28 is hinged to the end of the fixed rod C25 away from the shaft 24. A hose for conveying gas is fixedly connected to the side of the jet nozzle 28. The other end of the hose is connected to a jetting device to provide power for the jetting of the jet nozzle 28. Both sides of the air nozzle 28 are slidably connected to the fixing blocks 29, which are fixedly connected to the inner wall of the box 1. The reciprocating motion of the fixing rod C25 drives the air nozzle 28 to reciprocate in the groove of the fixing block 29 to clean the inside of the mold 3 by air jet. The mold 3 is detachably installed on one side of the top of the box 1. The side wall of the box 1 is provided with a slag outlet 5. The mold 3 is provided with detachable components 4 on both sides. The slag outlet 5 is provided with an inclined ramp inside, so that the residue that comes down easily can fall out automatically. The detachable components 4 ensure that the mold 3 can be disassembled and replaced or rotated to different angles.
[0035] Reference Figures 3-6The detachable component 4 includes two sets of limiting blocks 41. The left set of limiting blocks 41 is inserted into one side of the mold 3, and the right set of limiting blocks 41 is movably connected to the other side of the mold 3. By default, the two sets of limiting blocks 41 are inserted into the mold 3 to fix it. The left set of limiting blocks 41 is square columnar, and the right set of limiting blocks 41 is cylindrical. Sliding rods 42 are fixedly connected to the outer surface of the limiting blocks 41. Two sets of sliding grooves are opened inside the box body 1, and the two sets of sliding rods 42 are slidably connected to the upper end of the box body 1. When both sets of sliding rods 42 slide outward simultaneously, the limiting block 41 will disengage from the mold 3. At this time, the mold 3 can be disassembled and replaced. The sliding rods 42 are elastically connected to the inner wall of the box body 1 by springs 43. One end of each set of springs 43 is fixedly connected to the side wall of the sliding rod 42, and the other end of each spring 43 is fixedly connected to the inner wall of the box body 1. The springs 43 provide an inward restoring force to the sliding rods 42, so that the limiting block 41 will not disengage from the mold 3. The ends of the two sets of sliding rods 42 away from the limiting block 41 contact the cone 44. A slot is provided on the side of the box body 1 near the cone 44, and a sliding groove is provided on the inner wall of the slot. A slider is provided at the bottom of the cone 44, and the bottom of the cone 44 is slidably connected to the inner wall of the box body 1. When the cone 44 is pushed forward, the conical part squeezes the two sets of sliding rods 42, causing the sliding rods 42 to move outward and drive the limiting block 41 to disengage from the mold 3. The sliding groove inside the slot of the box body 1 ensures that the cone 44 is only allowed to reciprocate within the slot, and grooves are provided on both sides of the cylindrical part of the cone 44 to fix the cone 44 and prevent it from loosening. A gripping rod 45 is fixedly connected to the side wall of the left sliding rod 42. A sliding groove is provided on the side of the box body 1 near the gripping rod 45. The gripping rod 45 is slidably connected to the inner wall of the front end of the box body 1. The gripping rod 45 is used to control the left sliding rod 42 independently. When the gripping rod 45 is pushed, the left sliding rod 42 will move outward, so that the left limiting block 41 is separated from the mold 3. At this time, the mold 3 can be rotated freely, so that the arc surface of the mold 3 can be rotated upward to clean the inside of the mold 3 or the front surface can be rotated upward to combine with the upper core box for casting work.
[0036] Working principle: When the lower core box needs to be cleaned, first push the gripping rod 45 so that the left sliding rod 42 drives the left limiting block 41 to disengage from the mold 3. At this time, only the right cylindrical limiting block 41 supports the mold 3. Then the mold 3 can be manually flipped so that the front is facing down. Release the gripping rod 45. At this time, the left spring 43 provides a restoring force to the sliding rod 42 so that the left square cylindrical limiting block 41 is reinserted into the mold 3 to fix it. After it is completely fixed, start the motor 27. At this time, the output shaft of the motor 27 will drive the rotating disk 26 to rotate. The rotating disk 26 drives the fixed rod C25 to reciprocate around the center through the shaft 24. At this time, the jet nozzle 28 also slides back and forth in the groove of the fixed block 29 under the drive of the fixed rod C25 to spray air to clean the inside of the mold 3.
[0037] Meanwhile, the fixed rod B23 also reciprocates under the drive of the shaft 24. At this time, the hammer 22, supported by the fixed rod A21 and driven by the reciprocating motion of the fixed rod B23 on the inner wall of the box 1, causes the two sets of arc surfaces to repeatedly strike the upper surface of the box 1 through the rotation center axis of the hammer 22, transmitting the vibration into the mold 3 so that the residue falls off. The cleaning component 2 effectively cleans the stubborn residue that is difficult to clean in the mold 3 by combining air jet and knocking vibration. The cleaned residue will slide down through the slag outlet 5 with an inclined slope and collect at the outlet for easy subsequent centralized cleaning. If the mold 3 needs to be replaced, simply push the cone 44. At this time, the conical head will squeeze the two sets of sliding rods 42 so that the limiting block 41 is disengaged from the mold 3. At this time, the mold 3 can be disassembled and installed. The cone 44 has grooves on both sides of the column to provide fixation for the cone 44. The detachable component 4 can control one set of sliding rods 42 individually, providing flexible options for the disassembly or rotation of the mold 3.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
