Description

Technical Field

[0001] This utility model relates to a device for moving and adjusting the height of a sand mold. It belongs to the field of alloy casting processing technology. Background Technology

[0002] Magnesium alloys, due to their low density and high specific strength, are increasingly widely used in large components (typically weighing ≥50kg) in aerospace, automotive manufacturing, and other fields. However, magnesium alloys are highly chemically reactive and readily oxidize and burn upon contact with air at high temperatures (casting temperatures are typically 650-750℃). Furthermore, the molten alloy solution has high fluidity, requiring extremely high stability during the casting process. Existing sand-casting gravity casting processes for large magnesium alloy components suffer from the following core problems: 1. Cumbersome and inefficient operation: When changing molds, manual disassembly and positioning of the mold and gate structure are required, and a single mold change takes ≥2 hours; during the casting process, manual switching of the gate and cleaning of residual solution are required, and the processing cycle of a single product is as long as 4-6 hours, which is difficult to adapt to the needs of mass production.

[0003] 2. Insufficient environmental protection: The high-temperature fumes (including magnesium oxide dust and volatile organic compounds) generated during casting are not effectively collected and are directly discharged into the workshop environment, which not only pollutes the air but also endangers the health of workers. The dust concentration in the workshop often exceeds 10mg / m³, which does not meet environmental protection standards.

[0004] To address the aforementioned issues, there is an urgent need to design a fully automated and highly safe device for moving and adjusting the height of sand molds to meet the industrial production needs of large magnesium alloy products. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the prior art and provide a sand mold movement and height adjustment device to achieve efficient mold changing and dust collection during the casting process, while adapting to the general needs of multiple mold specifications.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A device for moving and adjusting the height of a sand mold, comprising: The workstation is quick-connected to multiple mold assembly components. As a fixed platform for casting operations, the workstation is equipped with multiple quick-connect sockets that can be quickly plugged into and unplugged to connect with the mold assembly components, achieving precise positioning and fixing of the mold with a positioning accuracy of ≤±2mm. The mold assembly includes a movable mold carriage, a lifting assembly mounted on the mold carriage for adjusting the height of the sand mold, a sand mold mounted on the lifting assembly, and a pouring cup mounted on the sand mold; the pouring cup has a pouring cup collection groove for facilitating solution pouring, a small pouring gate and a large pouring gate for slow pouring into the sand mold; Specifically, Mold trolley: Equipped with casters and locking mechanism at the bottom, it can move along the workshop track and be fixed to the workstation via quick-connect sockets. The time for a single movement and positioning is ≤5 minutes. Lifting assembly: Installed on the mold trolley, it adopts a screw or hydraulic drive structure to drive the sand mold to rise and fall vertically, with an adjustment range of 0-500mm to meet the casting requirements of different heights; the lifting assembly is a scissor-type lifting assembly or a hydraulic rod lifting assembly. Sand mold: It has a multi-layer splicing structure (2-4 layers, depending on the product size), and the outer wall is equipped with a mold limiting frame; Sprue cup: Installed on the top of the sand mold, it is fixed by "connecting shaft and mold limiting frame"; the sprue cup has a sprue cup collection groove (for collecting residual solution), a small sprue (10-15mm in diameter, for precise material replenishment) and a large sprue (30-40mm in diameter, for rapid casting).

[0007] It also includes an environmentally friendly ventilation system, which includes a shielding canopy located on the workstation and a suction pipe installed in the shielding canopy. The shielding canopy has a telescopic opening for a crane to lift the pouring cup.

[0008] Canopy: Covers the work platform and is made of high-temperature resistant flexible material. One side of the canopy is retractable (0-1.5m in length) to facilitate the hoisting of the pouring cup by a crane. Suction pipes: evenly distributed on the inner wall of the shielding canopy, connected to the workshop dust removal system through pipes, with a dust collection efficiency of ≥90%.

[0009] The mold trolley is fixedly connected to the workstation via a quick-connect socket, enabling quick assembly and disassembly.

[0010] A handle is installed at the rear end of the pouring cup. After casting is completed, the pouring cup is pulled up to prevent excess solution from entering the mold.

[0011] The sand mold has a multi-layer structure and is equipped with a mold limiting frame. The pouring cup is equipped with a connecting shaft that matches the mold limiting frame to limit the pouring cup and prevent it from shifting during the casting process.

[0012] It also includes a trackless trolley, which is equipped with a robotic arm detection component for detecting alloy solutions and a casting component for pouring the alloy solutions into molds.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The present invention relates to a sand mold movement and height adjustment device, which achieves fully automatic casting through the coordinated operation of the workstation, mold assembly assembly and environmental protection ventilation assembly, realizing intelligent and automated operation; Operational efficiency is significantly optimized: quick-connect connection and trackless trolley navigation enable rapid mold changing, reducing the time for a single mold change from ≥2 hours to ≤30 minutes; molds can also be assembled on other frames and transported to the casting workshop via mold trolleys, reducing the processing cycle of a single product from 4-6 hours to 2-3 hours, increasing production efficiency by more than 50%.

[0014] Environmental compliance: The dust collection efficiency of the environmentally friendly exhaust components is ≥90%, meeting the national "Emission Standard of Air Pollutants for Industrial Furnaces and Kilns". The dust concentration in the workshop is reduced to ≤5mg / m³, improving the working environment.

[0015] High level of intelligence: Fully automated coordinated control is achieved through a central control system, reducing human intervention and improving production stability and consistency. Attached Figure Description
