Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and in particular to a metal casting that is easy to clean. Background Technology

[0002] After machining, metal castings are prone to adhering to contaminants such as cutting fluid, metal shavings, and oxide scale. If cleaning is not thorough, it will affect the accuracy of subsequent assembly and may also cause corrosion of the castings. Traditional cleaning methods have obvious drawbacks: manual wiping is inefficient and it is difficult to clean stains in crevices; when cleaning with a high-pressure water gun, improper pressure control can easily damage the surface of the castings; and existing cleaning devices have poor sealing performance, making it easy for wastewater to leak and pollute the environment. Drainage requires manual operation, and water often accumulates due to forgetting to do so, further aggravating the corrosion of the castings. This brings many inconveniences to production operations and has certain adverse effects on people's use. In order to overcome the shortcomings of existing technologies, we propose a method for cleaning metal castings that is easy to clean. Utility Model Content

[0003] The main objective of this invention is to provide a metal casting that is easy to clean, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A metal casting for easy cleaning includes a support box and a top cover. A first sealing ring is fixedly connected to the upper end of the support box, and a sealing groove is provided at the lower end of the top cover. A water inlet pipe is fixedly connected to one side of the support box, and a valve is detachably connected to the middle of the water inlet pipe. A water collection chamber is provided inside the support box, and several mist nozzles communicating with the water collection chamber are detachably embedded on the inner surface of the support box. A drain pipe is detachably connected to the bottom of the support box. Multiple side through holes are provided on the outer wall of the drain pipe, and multiple connecting plates are fixedly connected to the inner wall of the drain pipe. A fixing cylinder is fixedly connected between the multiple connecting plates. A spring is detachably connected inside the fixing cylinder, and the upper end of the spring abuts against a limit plate. A connecting rod is fixedly connected to the upper end of the limit plate, and a conical top block is fixedly connected to the upper end of the connecting rod. A second sealing ring is embedded on the upper surface of the conical top block, and a cover cylinder is fixedly connected to the lower end of the conical top block.

[0005] Preferably, the first sealing ring is made of oil-resistant rubber, has a rectangular cross-section, the height of the first sealing ring is adapted to the depth of the sealing groove, and the outer contour dimension of the first sealing ring is clearance-fitted with the inner contour dimension of the sealing groove.

[0006] Preferably, the mist nozzles are arranged in a matrix on the inner surface of the support box, and the spray pressure of the mist nozzles is controlled by a valve on the water inlet pipe.

[0007] Preferably, the spring is a cylindrical helical compression spring made of high-strength spring steel, and a gap is left between the spring and the inner wall of the fixed cylinder.

[0008] Preferably, the second sealing ring is made of fluororubber with a circular cross-section. The inner diameter of the cover is adapted to the outer diameter of the fixed cylinder, and the cover is sleeved on the outside of the fixed cylinder with the two slidingly engaged.

[0009] Preferably, the connecting plates are evenly distributed radially around the axis of the fixed cylinder, and the connecting plates are welded to the inner wall of the drain pipe and the outer wall of the fixed cylinder.

[0010] Compared with the prior art, the present invention has the following beneficial effects: This easy-to-clean metal casting, through the matching and cooperation of the first sealing ring at the upper end of the support box and the sealing groove of the top cover, can effectively block the leakage path of sewage during the cleaning process, ensuring a dry working environment. At the same time, the matrix-arranged mist nozzles inside the support box are linked with the water inlet valve, which can flexibly adjust the spray pressure through the valve to ensure that the cleaning water evenly covers all areas of the metal casting, adapting to the cleaning needs of different stain adhesion levels. It solves the problems of incomplete cleaning of local areas, pressure loss damaging the casting, or sewage overflow that are common in the cleaning of existing metal castings, greatly improving the cleaning effect and operational safety.

[0011] This easy-to-clean metal casting features an automatic opening and closing structure inside the drain pipe, consisting of a spring, a conical top block, and a cover. The pressure generated by accumulated sewage automatically pushes the conical top block downwards, opening the side passage for drainage. After the sewage is drained, the spring returns to its original position, causing the conical top block to seal against the second sealing ring and seal the drain pipe. This structure eliminates the need for manual intervention in the drainage switch, solving the problem of existing cleaning devices requiring manual control of drainage, which can easily lead to forgotten drainage, water accumulation, and impurity growth. It also prevents external contaminants from entering the support box after cleaning, ensuring a clean storage environment for the casting and improving the ease of use and reliability of the device.

Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Example 1, as Figure 1 , Figure 2 and Figure 3 As shown, a metal casting for easy cleaning includes a support box 1 and a top cover 2. A first sealing ring 3 made of oil-resistant rubber with a rectangular cross-section is fixedly connected to the upper end of the support box 1. A sealing groove 4 adapted to the first sealing ring 3 is opened at the lower end of the top cover 2. The height of the first sealing ring 3 and the depth of the sealing groove 4 are matched, and their outer and inner contour dimensions are fitted with a clearance. A water inlet pipe 5 is fixedly connected to one side of the support box 1. A valve 6 for controlling the spray pressure of a mist nozzle 8 is detachably connected to the middle of the water inlet pipe 5. A water collection chamber 7 is opened inside the support box 1. Several mist nozzles 8 arranged in a matrix and communicating with the water collection chamber 7 are detachably embedded on the inner surface of the support box 1. A drain pipe 9 is detachably connected to the bottom of the support box 1. Multiple side through holes 1 are opened on the outer wall of the drain pipe 9. 0. Multiple connecting plates 11 are fixedly connected to the inner wall of the drain pipe 9 in a radially evenly distributed manner with the axis of the fixed cylinder 12 as the center. The connecting plates 11 are welded to the inner wall of the drain pipe 9 and the outer wall of the fixed cylinder 12. A cylindrical spiral compression spring 13 made of high-strength spring steel is detachably connected inside the fixed cylinder 12. A gap is left between the spring 13 and the inner wall of the fixed cylinder 12. The upper end of the spring 13 abuts against the limit plate 14. A connecting rod 15 is fixedly connected to the upper end of the limit plate 14. A conical top block 16 with a second sealing ring 17 of fluororubber material with a circular cross section is fixedly connected to the upper end of the connecting rod 15. A cover 18 with an inner diameter that matches the outer diameter of the fixed cylinder 12 is fixedly connected to the lower end of the conical top block 16. The cover 18 is sleeved on the outside of the fixed cylinder 12 and the two slide together.

[0016] It should be noted that this utility model is a metal casting that is easy to clean. In use, firstly, the first sealing ring 3 at the upper end of the support box 1 is embedded into the sealing groove 4 at the lower end of the top cover 2 to achieve a seal between the support box 1 and the top cover 2. Then, the valve 6 on the water inlet pipe 5 is opened, and external cleaning water enters the water collection chamber 7 in the support box 1 through the water inlet pipe 5. The water is then sprayed out at a set pressure through the matrix-type distributed mist nozzles 8 connected to the water collection chamber 7 to thoroughly rinse the metal casting in the support box 1. During the rinsing process, the sewage generated gradually gathers at the bottom of the support box 1 and flows into the drain pipe 9. When the sewage accumulates to a certain amount in the drain pipe 9, the sewage pressure pushes the conical top. As block 16 moves downward, the conical top block 16 drives the limiting plate 14 to compress the spring 13 inside the fixed cylinder 12 via the connecting rod 15. At the same time, the cover 18 at the lower end of the conical top block 16 slides along the outside of the fixed cylinder 12. At this time, the side through hole 10 on the drain pipe 9 opens, and sewage is discharged through the side through hole 10. After the metal casting is cleaned, the valve 6 on the water inlet pipe 5 is closed to stop the water inlet. The sewage pressure in the drain pipe 9 gradually decreases, and the spring 13 resets under its own elasticity, pushing the limiting plate 14, the connecting rod 15 and the conical top block 16 to move upward until the second sealing ring 17 on the conical top block 16 fits against the inner wall of the drain pipe 9, thus sealing the drain pipe 9.
