Description

Technical Field

[0001] This invention relates to the field of casting technology, and in particular to a lower core die support structure. Background Technology

[0002] The lower core fixture support is a device used to support sand cores. Most existing lower core fixture supports have multiple through holes to discharge casting sand that falls on the support, thereby improving the cleanliness of the support. Although this sand discharge method can remove the casting sand that falls on the support, some casting sand will still fall outside the through holes during use. At this time, workers need to manually clean the casting sand on the support. This process is not only time-consuming and labor-intensive, but also greatly reduces the casting progress of the workpiece. Therefore, we propose a lower core fixture support structure. Summary of the Invention

[0003] To address the technical problem of the inconvenience of using the lower core die support, this invention provides a lower core die support structure.

[0004] This invention is achieved using the following technical solution: a core die support structure, comprising a support body, the support body having multiple through holes, sliding grooves on both sides of the support body, guide blocks slidingly passing through the sliding grooves, fixed blocks fixed to adjacent guide blocks at both ends of the support body, loading grooves at both ends of the support body, and support blocks hinged to the inner walls of adjacent loading grooves at both ends of the support body. A control assembly for adjusting the support blocks is located below the support body. The support blocks support the sand core, and the through holes on the support body allow casting sand falling onto the support body to be discharged. Through the sliding cooperation of the sliding grooves and guide blocks, the support body reciprocates horizontally, causing the casting sand on the support body to shake. The shaking casting sand falls into the through holes and is discharged.

[0005] As a further improvement to the above solution, the control component includes a mounting frame fixed to the bottom of the support body. The mounting frame has threaded posts with opposite thread directions at both ends. Drive sleeves are threaded onto the outer walls of both ends of the threaded posts. A linkage block is fixed to the outer side of the drive sleeve. A control plate is hinged to the outer side of the linkage block. The end of the control plate away from the linkage block is hinged to an adjacent support block. A receiving box is fixed to the inner wall of the mounting frame below the threaded posts. An opening is provided at the bottom of the receiving box. Closing blocks for closing the opening are hinged to the inner walls at both ends of the opening. Multiple connecting springs, with their other ends fixed to the inner wall of the receiving box, are fixed to the side of the closing block closest to the limiting block. A through hole is provided at the bottom of the drive sleeve. A limiting block fixed to an adjacent closing block slides through the through hole. A linkage block corresponding to an adjacent support block is fixed to the movable end of the closing block. Through the operation of the control component, the corresponding angle of the support block can be adjusted, allowing the support block to be retracted and the casting sand inside the receiving box to be discharged.

[0006] As a further improvement to the above solution, sliding grooves are provided at both ends of the support body, and the control plate and the linkage block slide inside the adjacent sliding grooves. The sliding grooves allow the control plate and the linkage block to slide flexibly.

[0007] As a further improvement to the above solution, one of the fixed blocks has mounting blocks fixed at both ends on its inner side. A motor is fixed at one end of the mounting block near the main body of the support base. The output end of the motor is connected to a drive shaft. A drive plate is fixedly sleeved on the outer wall of the drive shaft away from the motor. A drive plate is hinged to the outer side of the movable end of the drive plate. The movable end of the drive plate is hinged to the outer side of the mounting frame. By running the motor, the drive shaft can be driven to rotate, causing the drive plate and drive plate to deflect, thereby causing the mounting frame, the main body of the support base, and the support block to move. The corresponding position of the support block can be adjusted. When the drive shaft rotates continuously, it will cause the main body of the support base to move back and forth.

[0008] As a further improvement to the above solution, a second motor is fixed to the outside of the mounting frame, one end of the threaded column is rotatably connected to the inner wall of the mounting frame, and the other end of the threaded column is drive-connected to the output end of the second motor. The threaded column can be driven to rotate by the operation of the second motor.

[0009] As a further improvement to the above solution, a limiting block is provided above the hinged end of the closed block. The limiting block is fixed on the inner wall of the receiving box, and the closed block can be limited by the limiting block.

[0010] As a further improvement to the above solution, the length of the loading slot is greater than the length of the support block, and the support block has an L-shaped structure. The support block can be stored in the loading slot, which is longer than the length of the support block.

[0011] As a further improvement to the above solution, the drive sleeve is a rectangular block that slides inside the mounting frame. The drive sleeve of the rectangular block can prevent the drive sleeve from deflecting during the displacement process.

[0012] As a further improvement to the above solution, the mounting frame is provided with an adapter hole, and the threaded column rotates inside the adapter hole, allowing the threaded column to rotate flexibly.

[0013] As a further improvement to the above solution, the length of the second drive plate is greater than the length of the first drive plate, and the first drive plate is offset from the mounting frame. By offsetting the first drive plate from the mounting frame, the installation frame can be prevented from interfering with the deflection of the first drive plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention can support the sand core and quickly discharge the casting sand that falls on the support base, avoiding the need for workers to manually clean the casting sand on the support base. It is convenient to use and the discharged casting sand can be recycled.

[0016] 2. The present invention allows for adaptive adjustment of the support base according to usage requirements, and the support components of the support base can be easily and conveniently stored, offering high flexibility. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example 1:

[0027] Combination Figure 1 and Figure 2 The embodiment of the lower core die support structure includes a support body 1, which has multiple through holes. The support body 1 has sliding grooves on both sides, and guide blocks 2 slide through the sliding grooves. The support body 1 has fixed blocks 3 at both ends that are fixed to the adjacent guide blocks 2. The support body 1 has loading grooves 4 at both ends, and support blocks 5 at both ends that are hinged to the inner walls of the adjacent loading grooves 4. The support body 1 has a control component for controlling the support blocks 5 at its lower part.

[0028] The implementation principle of a lower core die support structure in this application embodiment is as follows: the support block 5 can support the sand core, and the casting sand falling on the support body 1 can be discharged through the through hole on the support body 1. When casting sand falls outside the through hole, the support body 1 reciprocates horizontally through the sliding cooperation of the slide groove and the guide block 2, causing the casting sand on the support body 1 to shake. The shaking casting sand will fall into the through hole and be discharged.

[0029] Example 2:

[0030] Combination Figure 3 , Figure 4 and Figure 5This embodiment, based on embodiment 1, further improves upon the following: the control component includes a mounting frame 9 fixed to the bottom of the support body 1. The mounting frame 9 has threaded posts 10 with opposite thread directions at both ends. Drive sleeves 11 are threaded onto the outer walls of both ends of the threaded posts 10. A linkage block 12 is fixed to the outer side of the drive sleeve 11. A control plate 13 is hinged to the outer side of the linkage block 12. One end of the control plate 13 away from the linkage block 12 is hinged to an adjacent support block 5. A receiving box 16 is fixed to the inner wall of the mounting frame 9 below the threaded posts 10. An opening is provided at the bottom of the receiving box 16. Closing blocks 17 for closing the opening are hinged to the inner walls at both ends of the opening. Multiple connecting springs 19, with their other ends fixed to the inner wall of the receiving box 16, are fixed to the side of the closing block 17 closest to the limiting block 18. A through hole is provided at the bottom of the drive sleeve 11. A limiting block 15 fixed to an adjacent closing block 17 slides through the through hole. A linkage block 20 corresponding to the adjacent support block 5 is fixed to the movable end of the closing block 17. The casting sand discharged from the hole will be received by the receiving box 16. During the use of the support block 5, the rotation of the threaded column 10, through the threaded engagement of the threaded column 10 and the drive sleeve 11, drives the drive sleeve 11 and the linkage block 12 to move, drives the control plate 13 to move, and drives the support block 5 to deflect. At this time, the corresponding angle of the support block 5 can be adjusted. When the support block 5 needs to be stored, the rotation of the threaded column 10, through the threaded engagement of the threaded column 10 and the drive sleeve 11, drives the drive sleeve 11 and the linkage block 12 to move, drives the control plate 13 to move, and drives the support block 5 to deflect. When the support block 5 deflects into the interior of the loading groove 4, the support block 5 is stored. When the support block 5 enters the interior of the loading groove 4, the limiting block 15 will disengage from the through hole, and the support block 5 will press the linkage block 20, causing the linkage block 20 and the closing block 17 to deflect. At this time, the deflected closing block 17 will open the opening, and the casting sand located inside the receiving box 16 will be discharged.

[0031] The support body 1 has sliding grooves 14 at both ends. The control plate 13 and the linkage block 20 slide inside the adjacent sliding grooves 14. The control plate 13 and the linkage block 20 can slide flexibly through the sliding grooves 14.

[0032] Example 3:

[0033] Combination Figure 6This embodiment is further improved on the basis of embodiment 1 in that: two ends of the inner side of a fixed block 3 are fixed with mounting blocks 8. A motor is fixed at the end of the mounting block 8 near the support body 1. The output end of the motor is connected to a drive shaft. A drive plate 6 is fixedly sleeved on the outer wall of the end of the drive shaft away from the motor. A drive plate 7 is hinged to the outer side of the movable end of the drive plate 6. The movable end of the drive plate 7 is hinged to the outer side of the mounting frame 9. The operation of the motor drives the drive shaft to rotate. The rotating drive shaft drives the drive plate 6 to rotate, drives the drive plate 7 to deflect, drives the mounting frame 9 to move, drives the support body 1 to move, and drives the support block 5 to move. At this time, the corresponding position of the support block 5 can be adjusted. When the drive shaft rotates continuously, it will drive the support body 1 to reciprocate.

[0034] Motor 2 is fixed on the outside of mounting frame 9. One end of threaded column 10 is rotatably connected to the inner wall of mounting frame 9, and the other end of threaded column 10 is drive-connected to the output end of motor 2. Through the operation of motor 2, threaded column 10 can be driven to rotate.

[0035] A limiting block 18 is provided above the hinge end of the closing block 17. The limiting block 18 is fixed on the inner wall of the receiving box 16. The closing block 17 can be limited by the limiting block 18.

[0036] The length of the loading slot 4 is greater than the length of the support block 5. The support block 5 has an L-shaped structure. The support block 5 can be stored in the loading slot 4, which is longer than the support block 5.

[0037] The drive sleeve 11 is a rectangular block. The drive sleeve 11 slides inside the mounting frame 9. The drive sleeve 11 with the rectangular block can avoid deflection during the displacement process and improve the stability of the drive sleeve 11.

[0038] The mounting frame 9 has an adapter hole, and the threaded post 10 rotates inside the adapter hole, allowing the threaded post 10 to rotate flexibly.

[0039] The length of the second drive board 7 is greater than the length of the first drive board 6. The first drive board 6 is offset from the mounting frame 9. By offsetting the first drive board from the mounting frame 9, the mounting frame 9 can be prevented from interfering with the deflection of the first drive board 6.

[0040] Working principle: The support block 5 supports the sand core. Casting sand falling onto the support body 1 can be discharged through the through hole in the support body 1. The discharged casting sand is received by the receiving box 16. During the use of the support block 5, the rotation of the threaded column 10, through the threaded engagement between the threaded column 10 and the drive sleeve 11, causes the drive sleeve 11 and the connecting block 12 to move, which in turn causes the control plate 13 to move, thus causing the support block 5 to deflect. The angle of the support block 5 can be adjusted accordingly. When the support block 5 needs to be stored, the rotation of the threaded column 10, through the threaded engagement between the threaded column 10 and the drive sleeve 11, causes the drive sleeve 11 and the connecting block 12 to move, which in turn causes the control plate 13 to move, thus causing the support block 5 to deflect. When the support block 5 deflects into the loading groove 4, it is stored. When the sand is inside the through hole, the limiting block 15 will disengage from the through hole, and the support block 5 will press the linkage block 20, causing the linkage block 20 and the closing block 17 to deflect. At this time, the deflected closing block 17 will open the opening, and the casting sand inside the receiving box 16 will be discharged. When casting sand falls outside the through hole, the drive shaft will be driven to rotate by the operation of motor one. The rotating drive shaft will drive drive plate one 6 to rotate, drive drive plate two 7 to deflect, drive the mounting frame 9 to move, drive the support base body 1 to move, and drive the support block 5 to move. At this time, the corresponding position of the support block 5 can be adjusted. When casting sand falls outside the through hole, the drive shaft will rotate continuously. Through the sliding cooperation of the slide groove and guide block 2, the support base body 1 will be driven to reciprocate, causing the casting sand on the support base body 1 to shake. The shaking casting sand will fall into the through hole and be discharged.

[0041] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
