Technical Field

[0001] This utility model relates to the field of coated sand casting technology, specifically a coated sand shell mold for automobile rear suspension brackets. Background Technology

[0002] Coated sand casting is a process that uses natural quartz sand as raw sand and phenolic resin, hexamethylenetetramine, and reinforcing agents as raw materials to prepare a mold shell for casting. Due to its high strength, high surface finish of the mold shell, fewer casting process steps, and high production efficiency, it is often used for precision casting of larger workpieces.

[0003] In the existing technology, because the coating sand casting process requires filling the mold with coating sand, it is easy for too much coating sand to be filled, causing the coating sand to scatter and affect the working environment. At the same time, the temperature of the mold needs to be strictly controlled during the coating sand processing, and the finished product is prone to sticking to the mold, making it difficult to separate properly, thus affecting the processing efficiency. Therefore, it is necessary to improve the coating sand shell mold for automobile rear suspension brackets to solve the above problems. Utility Model Content

A gear column 516 is rotatably connected inside the connecting frame 513. A worm wheel 517 is fixedly connected to the outside of the gear column 516. A clamping plate 518 is slidably connected inside the base 514. A limit post 519 is fixedly connected to the end of the clamping plate 518 near the cover plate 512, which facilitates the adjustment of the position of the clamping plate 518, thereby satisfying the clamping and limiting of connecting pipes of external temperature control equipment of different sizes.

[0032] Furthermore, the worm 515 meshes with the worm wheel 517, the gear post 516 meshes with the cover plate 512, and the cover plate 512 and the corresponding position of the limiting post 519 are provided with grooves, and the limiting post 519 is movably connected inside the groove, which makes the clamping process more stable.

[0033] Furthermore, the demolding assembly 52 includes a connecting platform 521, which is fixedly connected inside the coated sand mold 1. A motor 522 is fixedly connected to the right side of the connecting platform 521. The output end of the motor 522 extends through the connecting platform 521 and is fixedly connected to a threaded rod 525 inside. A limit rod 526 is fixedly connected inside the connecting platform 521. A movable frame 523 is slidably connected to the outside of the limit rod 526.

[0035] Example 2:

[0036] Please see Figure 7-8 Furthermore, in conjunction with Embodiment 1, the auxiliary dust removal mechanism 6 includes a connecting frame 61, which is fixedly connected to the top of the coated sand mold 1. A protective box 62 is fixedly connected to the top of the connecting frame 61. A guide plate 63 is rotatably connected inside the connecting frame 61. A second gear 64 is fixedly connected to the top of the guide plate 63. An electric telescopic rod 65 is fixedly connected inside the protective box 62. A connecting plate 66 is fixedly connected to the front of the electric telescopic rod 65. A toothed plate 67 is fixedly connected to the bottom of the connecting plate 66.

[0038] In actual operation, when this device is used, it first employs a T-shaped screw to ensure its self-locking property. After the operator moves the device to the designated installation position, the installation and limiting are completed with the locking bolts. Then, the connecting frame 61 is connected to the external dust collector. The external dust collector works in conjunction with the connecting frame 61 to remove any excess coated sand that overflows between the coated sand lower mold 1 and the hydraulic cylinder 3. The electric telescopic rod 65 moves the connecting plate 66, causing the toothed plate 67 to slide inside the guide rail 68.

In the next step, the connecting waterway 511 is connected to the external temperature control equipment connecting pipe by thread. The workers use tools such as hex wrenches to rotate the worm gear 515. The rotation of the worm gear 515, in conjunction with the worm wheel 517, causes the gear column 516 to rotate inside the connecting frame 513, thereby causing the cover plate 512 to rotate outside the base 514. In conjunction with the limiting post 519, the clamping plate 518 slides inside the base 514 until the clamping plate 518 abuts and clamps with the external temperature control equipment connecting pipe. After processing is completed, the motor 522 is activated, causing the threaded rod 525 to rotate. In conjunction with the limiting rod 526, the movable frame 523 moves, thereby causing the ejector plate 524 to move, satisfying the ejection of the coated sand shell of the processed automobile rear suspension bracket.
