[0026] Specifically, when in use, the self-hardening sand mixed with the curing agent is added to the inside of the bridge shell mold body 1 through the pouring port, and the sliding table 4 is driven to slide back and forth by the shaking component 5, so that the bridge shell mold body 1 is shaken back and forth, eliminating the bubbles inside the bridge shell, making the bridge shell thicker, thereby avoiding the situation where the hardness of the product is reduced due to the generation of bubbles in the bridge shell.

[0027] Reference Figure 3The shaking assembly 5 includes a sliding frame 51 and a driver 52. Both ends of the sliding frame 51 are slidably installed inside the mounting cavity 3. The top of the sliding frame 51 is fixedly connected to the bottom end of the sliding table 4. The driver 52 is fixedly installed at the bottom of the processing table 2. The driving end of the driver 52 passes through the processing table 2 and extends to the inside of the mounting cavity 3. The driving end of the driver 52 is fixedly connected to the wheel disc 53. The inside of the sliding frame 51 is slidably connected to the slider 55. The top non-center part of the wheel disc 53 is fixedly connected to a connecting column 54. The top of the connecting column 54 is rotatably connected to the bottom end of the slider 55.

[0028] Specifically, the driver 52 drives the wheel 53 to rotate, and when the wheel 53 rotates, it drives the slider 55 to slide back and forth inside the sliding frame 51, and pushes the sliding frame 51 to slide back and forth, thereby driving the sliding platform 4 to slide back and forth.

[0029] Reference Figure 4 The cooling assembly 6 includes several cooling channels 61 and a connecting frame 62. The cooling channel 61 is opened at the side wall of the bridge housing mold body 1. The outer wall of the cooling channel 61 is fixedly connected with a ventilation end 64. The ventilation end 64 is connected to the air cooling equipment through a pipeline. The outer wall of the bridge housing mold body 1 is slidably connected with several slide grooves 7. The two ends of the connecting frame 62 are slidably connected to the slide groove 7. The side wall of the connecting frame 62 is fixedly connected with a sealing column 63 corresponding to the cooling channel 61. One end of the sealing column 63 is located inside the shaping groove and is consistent with the curvature of the inner wall of the shaping groove. The two ends of the connecting frame 62 are respectively fixedly connected with a tension spring 65, and the other end of the tension spring 65 is fixedly installed on the inner wall of the slide groove 7.

[0030] Specifically, when the bridge shell product in the shaping groove is not fully hardened, the connecting frame 62 is pulled outward to stagger the ventilation end 64 of the sealing column 63, and then cooling gas is introduced from the ventilation end 64. The cooling gas enters the interior of the bridge shell mold body 1 through the cooling channel 61, and accelerates the cooling and drying of the product in the shaping groove, so that the bridge shell in the shaping groove hardens quickly, thereby making it easier for workers to remove the bridge shell from the shaping groove and shortening the natural drying time.

[0031] Reference Figure 4 - Figure 5 The cooling assembly 6 also includes a plurality of positioning grooves 66 and positioning columns 67. The positioning grooves 66 are provided on the surfaces of the two upper connecting frames 62. The positioning columns 67 are fixedly mounted on the tops of the two lower connecting frames 62.

A card slot is provided on the top of the card block 69, and an oblique groove is provided on the outer side wall of the card block 69.

[0032] Specifically, the tension of the tension spring 65 causes the connecting frame 62 to press against the cooling channel 61, so that when the upper mold 11 and the lower mold 12 are docked and installed, the positioning groove 66 and the positioning column 67 can be docked, thereby connecting the upper and lower connecting frames 62. When cooling is required, the connecting frame 62 is pulled outward, and the connecting frame 62 pushes the block 69 to move downward until it reaches the slot. The block 69 moves upward due to the rebound force of the spring telescopic rod 68, and then the block 69 is stuck to the connecting frame 62, thereby opening the cooling channel 61, so that the cooling gas can flow through the cooling channel 61.

[0033] Working principle: When the device is needed, the self-hardening sand mixed with the curing agent is added to the inside of the bridge shell mold body 1 from the pouring port, and the driver 52 drives the wheel 53 to rotate. When the wheel 53 rotates, it drives the slider 55 to slide back and forth inside the sliding frame 51, and pushes the sliding frame 51 to slide back and forth, thereby driving the sliding platform 4 to slide back and forth, so that the bridge shell mold body 1 can rock back and forth, eliminate the bubbles inside the bridge shell, make the bridge shell thicker, and thus avoid the situation where the hardness of the product is reduced due to bubbles in the bridge shell. When the bridge shell product in the shaping groove is not fully hardened, the connecting frame 62 is pulled outward to stagger the ventilation end 64 of the sealing column 63, and then cooling gas is introduced from the ventilation end 64. The cooling gas enters the inside of the bridge shell mold body 1 through the cooling channel 61, and accelerates the cooling and drying of the product in the shaping groove, so that the bridge shell in the shaping groove hardens quickly, thereby making it convenient for workers to remove the bridge shell from the shaping groove and shortening the natural drying time. The tension of the tension spring 65 makes the connecting frame 62 press against the cooling channel 61, so that when the upper mold 11 and the lower mold 12 are docked and installed, the positioning groove 66 and the positioning column 67 can be docked, thereby connecting the upper and lower connecting frames 62. When cooling is required, the connecting frame 62 is pulled outward, and the connecting frame 62 pushes the block 69 to move downward until it reaches the slot. The block 69 moves upward due to the rebound force of the spring telescopic rod 68, and then the block 69 is stuck to the connecting frame 62, thereby opening the cooling channel 61 and allowing the cooling gas to flow through the cooling channel 61.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
