Description
Technical Field
[0001] This utility model relates to the technical field of box lifting equipment, and in particular to a pressurization device for a box lifting device. Background Technology
[0002] Currently, sand casting is a casting method that produces castings in sand molds. Steel, iron, and most non-ferrous alloy castings can be obtained using sand casting. Because the molding materials used in sand casting are inexpensive and readily available, and mold making is simple, it is suitable for single-piece production, batch production, and mass production of castings, and has long been a fundamental process in casting production. In existing technology, when casting using molding sand, a template is placed between the upper and lower sand boxes, molding sand is added to the sand boxes, and then the molding sand is compacted using a molding machine's pressure plate to create a sand mold. After the sand mold is removed, molten metal is poured into it, and after the molten metal solidifies, the outer layer of sand is removed, thus completing the casting.
[0003] When the existing equipment places the sleeve on the sand mold, it relies solely on the weight of the sleeve itself, which may result in improper placement, causing problems such as misalignment or molten iron leakage, thus affecting the quality of the casting. Furthermore, the existing equipment has limited applicability as it is difficult to adjust the pressure position according to different sleeve sizes and sand mold requirements. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pressurizing device for a box lifting device, comprising a bracket and a pressurizing assembly. The pressurizing assembly is fixedly connected to the top of the bracket. The pressurizing assembly includes a cylinder fixedly connected to the top of the bracket. A cylinder flange is fixedly connected to the bottom of the cylinder. A sealing ring is fixedly connected to the top of the cylinder flange. The inner wall of the sealing ring is tightly fitted with the end of the cylinder. A support plate is fixedly connected to the bottom of the cylinder flange. Two guide supports are fixedly connected to the top of the bracket. A guide hole is opened on the top of the guide support. A guide rod is inserted into the inner wall of the guide hole.
[0006] Furthermore, a guide flange is fixedly connected to the bottom of the guide rod, and the bottom of the guide flange is fixedly connected to the top of the support plate.
[0007] Furthermore, two grooves are formed on the surface of the support plate, and pressure rods are inserted and connected to the inner walls of the two grooves.
[0008] Furthermore, the surfaces of the two pressure rods are provided with spiral patterns, and the inner walls of the spiral patterns are threaded with fasteners. Each pressure rod has two fasteners, which abut against the top and bottom of the support plate, respectively.
[0009] Furthermore, the bottom of the bracket is fixedly connected to two connecting plate frames, and the inner wall of the connecting plate frames is threaded with connecting screws.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting up a pressurizing component, the cylinder can provide a stable and controllable pressure output. The pressure is transmitted to the support plate through the cylinder flange, realizing effective pressurization of the casing. The sealing ring on the top of the cylinder flange fits tightly against the cylinder end to prevent gas leakage and ensure the working efficiency and pressure stability of the cylinder.

The guide flange firmly connects the guide rod to the support plate, enhancing the overall strength of the guide structure. The sliding groove on the surface of the support plate cooperates with the pressure rod. The position of the pressure rod in the sliding groove can be adjusted by the spiral pattern on the surface and the fasteners, thereby adapting to casings of different sizes and adjusting the pressurization coverage. All components of the pressurizing component work together to significantly improve the stability and accuracy of pressurization and ensure the compaction quality of the molding sand.
[0014] 2. In this utility model, by setting an adjustment component, the guide wire is slidably connected to the slot on the surface of the pressure rod, providing a flexible moving track for adjusting the position of the pressure rod. The bidirectional telescopic rod can adjust the distance between the two pressure rods according to the size of the casing and the pressurization requirements.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a pressurizing device for a box lifting device, including a bracket 1 and a pressurizing component 2, with the pressurizing component 2 fixedly connected to the top of the bracket 1.
[0024] The following section will explain the specific settings and functions of its pressurization component 2 and adjustment component 5.
[0025] In this embodiment: the pressurizing component 2 includes a cylinder 21 fixedly connected to the top of the bracket 1, a cylinder flange 22 fixedly connected to the bottom of the cylinder 21, a sealing ring fixedly connected to the top of the cylinder flange 22, the inner wall of the sealing ring tightly fitting the end of the cylinder 21, a support plate 23 fixedly connected to the bottom of the cylinder flange 22, and two guide supports 24 fixedly connected to the top of the bracket 1. The top of the guide supports 24 is provided with a guide hole 25, and a guide rod 26 is inserted into the inner wall of the guide hole 25.
[0026] The effect achieved by the above components is as follows: by setting the cylinder 21 to output stable and adjustable air pressure, it is converted into vertical downward pressure and transmitted to the support plate 23 through the cylinder flange 22, realizing efficient pressurization of the casing. The sealing ring at the top of the cylinder flange 22 is tightly attached to the end of the cylinder 21 to form a sealing structure, which effectively prevents compressed gas leakage, ensures stable pressure output of the cylinder 21, and improves pressurization efficiency.
[0027] Specifically, a guide flange 27 is fixedly connected to the bottom of the guide rod 26, and the bottom of the guide flange 27 is fixedly connected to the top of the support plate 23.
[0028] The effect achieved by the above components is as follows: by setting the guide flange 27 to firmly connect the guide rod 26 and the support plate 23, the stability and connection strength of the guide structure are enhanced. During the lifting and lowering of the support plate 23, the guide flange 27 ensures that the guide rod 26 and the support plate 23 move synchronously, preventing the guide rod 26 and the support plate 23 from becoming loose or detached, and ensuring the reliability of the overall structure of the pressurizing assembly 2.
[0029] Specifically, two grooves 28 are formed on the surface of the support plate 23, and pressure rods 29 are inserted and connected to the inner walls of the two grooves 28.
[0030] The effect achieved by the above components is as follows: by setting the slide groove 28 to provide a sliding track for the pressure rod 29, the pressure rod 29 can move in a specific direction on the surface of the support plate 23. The position can be adjusted according to the size of the box and the distribution of molding sand, thereby changing the pressure application point and realizing flexible adaptation to boxes of different specifications.
[0031] Specifically, the surfaces of the two pressure rods 29 are provided with spiral patterns 210, and the inner walls of the spiral patterns 210 are threaded with fasteners 211. Each pressure rod 29 has two fasteners 211, which abut against the top and bottom of the support plate 23 respectively.
[0032] The effect achieved by the above components is as follows: by setting the spiral 210 to cooperate with the fastener 211, the position of the pressure rod 29 in the slide groove 28 is locked. The operator can adjust the position of the pressure rod 29 according to actual needs and then tighten the fastener 211 to make it tightly abut against the top and bottom of the support plate 23, so as to firmly fix the pressure rod 29, prevent the pressure rod 29 from shifting during the pressurization process, and ensure the accuracy of the pressurization position.
[0033] Specifically, the bottom of the bracket 1 is fixedly connected to two connecting plate frames 3, and the inner wall of the connecting plate frames 3 is threaded with connecting screws 4.
[0034] The effects achieved by the above components are as follows: by setting the connecting plate frame 3 and the connecting screw 4, an installation interface is provided for the pressurizing device, which makes it easy to fix the entire device on the box lifting equipment or other support structure, facilitates disassembly and installation, and provides reliable connection strength to ensure that the pressurizing device remains stable during operation and will not loosen due to vibration or other factors.
[0035] Specifically, an adjustment component 5 is fixedly connected to the bottom of the support plate 23. The adjustment component 5 includes a guide wire 51 fixedly connected to the bottom of the support plate 23, and slots 52 are opened on the surface of the two pressure rods 29. The surface of the guide wire 51 is slidably connected to the two slots 52.
[0036] The effect achieved by the above components is as follows: by setting the guide wire 51 to slide into the slot 52 of the pressure rod 29, the adjustment of the pressure rod 29 is guided and supported. The guide wire 51 restricts the swing of the pressure rod 29 during the adjustment process, ensuring that the pressure rod 29 moves smoothly along the predetermined direction, making the position adjustment of the pressure rod 29 more accurate and smooth.
[0037] Specifically, a bidirectional telescopic rod 53 is fixedly connected to the top of the guide wire 51, and an arc-shaped connecting plate 54 is fixedly connected to the two telescopic ends of the bidirectional telescopic rod 53. The surface of the arc-shaped connecting plate 54 is fixedly connected to the surface of the pressure rod 29.
[0038] The effect achieved by the above components is as follows: by setting the bidirectional telescopic rod 53, the distance between the two pressure rods 29 can be adjusted synchronously according to the size requirements of the box. When it is necessary to adapt to boxes of different widths, the bidirectional telescopic rod 53 extends and retracts, driving the arc-shaped connecting plate 54 to move, thereby pushing the pressure rod 29 to slide in the slot 52 and the slide groove 28, realizing the rapid adjustment of the position of the pressure rod 29. The arc-shaped connecting plate 54 is fixedly connected to the pressure rod 29 to ensure the uniform transmission of force, so that the adjustment of the two pressure rods 29 is synchronous and stable, improving the adaptability and adjustment efficiency of the pressurizing device to boxes of different specifications.
[0039] Working principle: By setting up the pressurizing component 2, the cylinder 21 can provide a stable and controllable pressure output. The pressure is transmitted to the support plate 23 through the cylinder flange 22, realizing effective pressurization of the casing. The sealing ring on the top of the cylinder flange 22 is tightly fitted to the end of the cylinder 21 to prevent gas leakage and ensure the working efficiency and pressure stability of the cylinder 21. The two guide supports 24 and their internal guide holes 25 cooperate with the guide rod 26 to provide precise guidance for the lifting and lowering movement of the support plate 23, ensuring that the support plate 23 is pressurized. 3. No deviation or shaking will occur, allowing the casing to be pressurized evenly. The guide flange 27 firmly connects the guide rod 26 to the support plate 23, enhancing the overall strength of the guide structure. The groove 28 on the surface of the support plate 23 cooperates with the pressure rod 29. The pressure rod 29 can be adjusted in position within the groove 28 through the spiral pattern 210 on its surface and the fastener 211, thereby adapting to casings of different sizes and adjusting the pressurization coverage. All components of the pressurization assembly 2 work together, significantly improving the stability and accuracy of pressurization and ensuring the compaction quality of the molding sand.
[0040] By setting the adjustment component 5, the guide wire 51 is slidably connected to the slot 52 on the surface of the pressure rod 29, providing a flexible moving track for adjusting the position of the pressure rod 29. The bidirectional telescopic rod 53 can extend and retract to adjust the distance between the two pressure rods 29 according to the size of the casing and the pressurization requirements. The arc-shaped connecting plate 54 drives the pressure rod 29 to slide in the slide groove 28, realizing adaptive adjustment for casings of different specifications and changing the pressurization position. The adjustment component 5 and the pressurization component 2 cooperate with each other, enabling the pressurization device to quickly adapt to diverse production needs, effectively solving the problem of poor applicability of existing devices, and improving the versatility and production efficiency of the equipment.
