[0002] In the foundry industry, the foundry of coated sand generally needs to adopt the mode of combining upper and lower molds (or multiple molds) and pouring molten iron inside for casting, however, due to the adoption of the mode of combining molds, the phenomenon of molten iron leakage often occurs due to insufficient mold closing pressure.

[0003] According to the foundry coated sand mold pressing device disclosed in Chinese patent publication No. CN222113470U, the cooling plate is arranged on the bottom plate, and the lower mold plate is slidingly arranged on the cooling plate. The upper mold plate is controlled to descend and extrude the clamping plate by the air cylinder, so that the mold can be clamped. After the device is heated and shaped, in order to facilitate cooling of the mold, the cooling liquid transported by the water pump circulates in the cooling plate, accelerating the cooling speed of the mold and improving the working efficiency. However, in actual use, the mold needs to be placed in the sliding groove and fixed by two clamping plates. After the mold is cast and cooled, the mold needs to be taken out from the sliding groove. When taking out the mold, the mold needs to be manually lifted from the sliding groove. At this time, it is not very convenient to quickly take out the mold because of the obstruction of the two clamping plates, and there is a certain safety hazard when the hand is inserted into the sliding groove. Therefore, a foundry coated sand mold pressing device is proposed to solve the above problems. SUMMARY

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1-5 As shown, the present invention proposes a casting coated sand mold pressing device, including a base plate 1, four support rods 2 on the base plate 1, a cooling mechanism 4 on the top of the four support rods 2, a placement shell 3 movably connected above the cooling mechanism 4, a pushing mechanism 5 inside the placement shell 3, and a squeezing mechanism 6 inside the placement shell 3.

[0026] In this invention, the base plate 1 and four support rods 2 can stably install and support the placement shell 3 and the cooling mechanism 4. The placement shell 3 can be used to place the mold. After placement, the extrusion mechanism 6 can press the mold to ensure its stability during casting. After casting, the cooling mechanism 4 can quickly cool the mold. After cooling, the pushing mechanism 5 can push the mold to quickly detach it from the placement shell 3, making it easy for workers to remove the mold and greatly improving the efficiency of mold casting.

[0027] In an optional embodiment, the pushing mechanism 5 includes a U-shaped plate 51, a threaded sleeve 52, a driving assembly 53, a threaded rod 54, a pushing block 55, a connecting rod 56, and a T-shaped assembly 57. The U-shaped plate 51 is disposed on the back side of the housing 3. The threaded sleeve 52 is rotatably connected to the back side of the U-shaped plate 51 via a bearing and extends into the interior of the housing 3. The driving assembly 53 is disposed inside the U-shaped plate 51, and the output end of the driving assembly 53 is connected to the threaded sleeve 52. The threaded rod 54 is threadedly connected to the interior of the threaded sleeve 52. The pushing block 55 is disposed on the front side of the threaded rod 54. The connecting rod 56 is disposed on the outside side of the pushing block 55. The T-shaped assembly 57 is disposed at the bottom of the connecting rod 56.

[0028] It should be noted that after the mold casting and cooling are completed, the pressure on the mold is released, and the threaded sleeve 52 can be rotated by the drive component 53. Under the action of the connecting rod 56 and the T-shaped component 57, the push block 55 will not rotate. The push block 55 can prevent the threaded rod 54 from rotating. When the threaded sleeve 52 rotates, under the action of the thread thrust, the threaded sleeve 52 will drive the threaded rod 54 to move forward or backward. The threaded rod 54 will drive the push block 55 to move forward or backward. When the push block 55 moves forward, it will push the mold forward, so that the mold can be separated from the placement shell 3. This makes it convenient for the staff to remove the mold and avoids the safety hazard of the staff reaching into the placement shell 3 to remove the mold.

[0029] In an optional embodiment, the drive assembly 53 includes a drive servo motor 531, a rotating shaft 532, a worm gear 533, and a worm wheel 534. The drive servo motor 531 is located on the right side of the U-shaped plate 51. The rotating shaft 532 is located on the output shaft of the drive servo motor 531 and extends into the interior of the U-shaped plate 51. The left end of the rotating shaft 532 is rotatably connected to the left side wall of the inner cavity of the U-shaped plate 51. The worm gear 533 is located on the outside of the rotating shaft 532, and the worm wheel 534 is located on the outside of the threaded sleeve 52. The worm gear 533 and the worm wheel 534 mesh with each other.

[0030] It should be noted that when the drive servo motor 531 is started, the output shaft of the drive servo motor 531 will drive the rotating shaft 532 to rotate, the rotating shaft 532 will drive the worm 533 to rotate, the worm 533 will drive the worm wheel 534 meshing with it to rotate, and the worm wheel 534 will drive the threaded sleeve 52 to rotate.

[0031] In an optional embodiment, the T-shaped component 57 includes a T-shaped block 571 and a T-shaped groove 572. The T-shaped block 571 is located at the bottom of the connecting rod 56, and the T-shaped groove 572 is formed in the inner bottom wall of the housing 3. The T-shaped block 571 is slidably connected to the inside of the T-shaped groove 572.

[0032] It should be noted that when the push block 55 moves forward or backward, it will drive the connecting rod 56 to move forward or backward. The T-shaped block 571 and the T-shaped groove 572 can limit and guide the connecting rod 56 to ensure its stability during movement. At the same time, under the action of the connecting rod 56, the T-shaped block 571 and the T-shaped groove 572, the push block 55 can be prevented from rotating, and the threaded rod 54 can be further prevented from rotating.

[0033] In an optional embodiment, the extrusion mechanism 6 includes two cylinders 61, two extrusion plates 62, and two sets of guide components 63. The two cylinders 61 are respectively located on the left and right sides of the housing 3 and extend into the interior of the housing 3. The two extrusion plates 62 are respectively located on the piston rods of the two cylinders 61. The two extrusion plates 62 are slidably connected to the interior of the housing 3. The two sets of guide components 63 are respectively located at the bottom of the two extrusion plates 62.

[0034] It should be noted that before pouring, the mold is placed inside the housing 3, and then the two cylinders 61 are activated. The piston rods of the two cylinders 61 will drive the two extrusion plates 62 to move to the opposite side or the opposite side. When the two extrusion plates 62 move to the opposite side and the opposite side of the two extrusion plates 62 abuts against the left and right sides of the mold, the mold can be pressed by the two extrusion plates 62 to avoid the phenomenon of molten iron leakage due to insufficient mold closing pressure during pouring. The two sets of guide components 63 can guide the two extrusion plates 62 respectively to ensure the stability of the movement of the two extrusion plates 62.

[0035] In an optional embodiment, both sets of guide components 63 include guide grooves 631 and guide blocks 632. The two guide grooves 631 are both formed on the inner bottom wall of the housing 3, and the two guide blocks 632 are respectively disposed at the bottom of the two extrusion plates 62. The two guide blocks 632 are slidably connected to the inside of the two guide grooves 631.

[0036] It should be noted that the extrusion plate 62 can be guided by the guide groove 631 and the guide block 632 to ensure the stability of the extrusion plate 62 during movement, thereby further improving the stability when pressing the mold.

[0037] In an optional embodiment, the front of the housing 3 is connected to the outside, and the controller 7 is provided on the right side of the housing 3.

[0038] It should be noted that the mold can be easily discharged from the front of the housing 3 by placing it on the front side. The cooling mechanism 4, the drive servo motor 531 and the cylinder 61 are all electrically connected to the controller 7. The controller 7 can control the cooling mechanism 4, the drive servo motor 531 and the cylinder 61.

[0039] In an optional embodiment, the cooling mechanism 4 includes a cooling plate, a liquid storage tank, a shaft, and a float, etc. The cooling mechanism 4 can quickly cool the mold after it has been poured.

[0040] Working principle:

[0041] In use, the casting coated sand mold clamping device first places the mold inside the placement housing 3, then activates two cylinders 61, causing two extrusion plates 62 to move to opposite sides. When the opposite sides of the two extrusion plates 62 abut against the left and right sides of the mold respectively, the mold is clamped, and then casting is performed. After casting is completed, the mold can be quickly cooled by the cooling mechanism 4. After cooling, the two cylinders 61 are activated in reverse, causing the two extrusion plates 62 to move to opposite sides, releasing the clamping of the mold. Then, the drive servo motor 531 is activated, causing the push block 55 to move forward. The push block 55 will drive the mold forward, allowing the mold to quickly detach from the placement housing 3, making it easy for workers to remove the mold and greatly improving the efficiency of mold casting. After the mold is removed, the drive servo motor 531 is activated in reverse, causing the push block 55 to move backward. When the push block 55 returns to its initial position, the next casting can begin.
