Description

Technical Field

[0001] This utility model relates to the field of casting, specifically to a sand box protection device. Background Technology

[0002] The sand box plays a crucial role in the casting process, and its main functions include:

[0003] (1) Supporting and fixing the sand mold: The sand box supports and fixes the sand mold through its structure and design, ensuring that the sand mold will not deform or move during the pouring process. (2) Controlling the pouring process: The design and size of the sand box need to ensure a reasonable amount of sand between the pattern and the sand box wall, and the tolerance of the positioning device must ensure dimensional accuracy to ensure the quality of the casting. (3) Facilitating operation and management: The structure of the sand box should be easy to manufacture and use, and the specifications should be standardized, serialized, and universal as much as possible to reduce manufacturing and management costs.

[0004] The gating gate in a sand mold is typically located at the top. In sand casting, the gating gate's location significantly impacts the quality of the casting. A top-mounted gating gate effectively controls the flow of molten metal, ensuring the metal surface rises at the necessary speed within the mold cavity, thus preventing gas entrapment and excessive oxidation. Furthermore, a top gating design saves metal, resulting in a simpler, more compact structure that is easier to clean.

[0005] Based on the above, during casting, workers typically need to work on top of the sand box. However, since sand boxes are usually assembled boxes, there are no protective devices around the top of the sand box. For large castings, the height of the sand box required can be more than 3 meters. When workers are working on top of the sand box, they are in an unprotected environment, and there is a risk that workers may accidentally fall from the sand box. Therefore, the current sand box poses a safety hazard during operation. Utility Model Content

[0006] This utility model provides a sand box protection device, which can eliminate the safety hazard of workers falling into the sand box when working on top of the sand box.

[0023] like Figures 1 to 2 As shown, the sand box protection device of this utility model includes a sand box body 1 and multiple protection units arranged around the sand box body 1. Each protection unit includes: a plug-in seat 2, a bracket 3, a support beam 4, and a telescopic protection component 5. The plug-in seat 2 is fixed to the sand box body 1; the bracket 3 is plugged into the plug-in seat 2; the support beam 4 is plugged into the bracket 3; and the telescopic protection component 5 is movably connected to the support beam 4. A part of the telescopic protection component 5 is located on the lower side of the support beam 4, and the other part of the telescopic protection component 5 is located on the upper side of the support beam 4.

[0024] In use, the bracket 3 is inserted into the connector 2, the support beam 4 is passed through the bracket 3, the telescopic protective component 5 is hung on the support beam 4, and a force is applied to the telescopic protective component 5 to stretch it out, making it a fence structure. Thus, the protective unit surrounds the top of the sand box body 1. When workers are working in the area surrounded by the protective unit, the blocking effect of the protective unit can prevent workers from falling from the top of the sand box. Therefore, this utility model eliminates the safety hazard of workers falling when working on the top of the sand box body 1, and ensures the safety of workers.

[0025] In this embodiment, the plug-in seat 2 is a sleeve that is closed at one end and open at the other end. The sleeve is welded and fixed to the sand box body 1. Plug-in seats 2 are installed at each corner of the sand box body 1. In this embodiment, the top of the sand box body 1 is a cuboid structure. Therefore, at least two plug-in seats 2 are welded and fixed on each outer wall of the sand box body 1.

[0026] The bracket 3 includes a support rod 3a and a support sleeve 3b. The support rod 3a is inserted into the connector 2, and the support sleeve 3b is fixed to the support rod 3a.
