Description

Technical Field

[0001] This utility model relates to the field of die-casting mold technology, specifically a device for removing carbon deposits from die-casting molds. Background Technology

[0002] Die casting molds are the core forming tools in metal pressure casting processes, widely used in industries such as automobiles, motorcycles, electronics, and hardware to efficiently and precisely produce complex-shaped metal parts. During die casting, high-temperature molten metal is injected into the mold cavity under high pressure and rapidly cooled to form the final shape. However, due to the contact between the molten metal and the mold surface, repeated spraying of release agents and high-temperature carbonization, as well as metal oxidation, a dense, hard carbon deposit inevitably accumulates in the mold cavity, runners, ejector pin holes, and other areas. This carbon deposit mainly consists of carbides, oxides, release agent residues, and metal shavings. If not removed promptly and effectively, carbon deposits will significantly reduce the surface finish of the casting, leading to defects such as scratches and pitting; affect the mold's thermal conductivity, exacerbate mold thermal stress, and shorten mold life; increase demolding resistance, potentially causing ejector pin jamming or casting deformation; and in severe cases, even alter the dimensional accuracy of the cavity, directly impacting product yield and production efficiency.

[0003] Currently, the industry commonly uses compressed air-powered sandblasting technology to remove carbon deposits from die-casting molds. In practice, most factories rely on manual hand-held sandblasting guns, using high-speed jets of sand or steel shot to impact the mold surface and remove the carbon layer through physical impact. However, this traditional manual sandblasting method has significant drawbacks: during the cleaning process, the high-speed sand jet impacting the carbon deposit surface generates a large amount of fine dust particles. Due to the open, close-range operation and the lack of effective dust source control measures, this dust, containing harmful components such as metal oxides and silicates, easily diffuses and spreads throughout the work area, causing serious air pollution. This not only results in a harsh working environment, directly threatening the respiratory health of operators, but the diffused dust also settles on workshop equipment, other molds, and products, causing secondary pollution, increasing the additional cleaning burden, and posing certain safety hazards.

[0004] Based on this, a carbon deposit removal device for die casting molds is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

The transmission belt 34 drives the sandblasting gun body 30 to move through the moving seat 33, so as to clean the remaining positions of the mold body 29. The output end of the second electric cylinder 37 drives the mounting box 36 to move, so as to adjust the distance between the working end of the sandblasting gun body 30 and the mold body 29.

[0034] Example 2

[0035] The difference from Embodiment 1 is that: a material collection hood 40 is fixedly installed in the mounting groove at the upper end of the workbench 47, a connecting box 41 is installed at the end of the material collection hood 40, a collection box 42 is provided inside the connecting box 41, and mounting holes are symmetrically provided at the upper end of the connecting box 41. A dustproof net 43 is installed in the mounting hole. In use, the sandblasting gun body 30 uses high-speed sprayed sand particles to impact the surface of the mold, and removes the carbon deposit layer by relying on physical impact force. Subsequently, the sand and carbon deposits enter the collection box 42 through the material collection hood 40, and at the same time, excess gas is discharged through the mounting hole. The dustproof net 43 can filter the dust in the gas. It is worth noting that the sandblasting component 31 uses existing components, and the specific structure and working principle are well known, so they will not be described in detail here.

[0036] The end of the material collection hood 40 is slidably provided with an installation frame 44, and a screening screen 45 is installed inside the installation frame 44. The screening screen 45 is cone-shaped. In use, the screening screen 45 can easily filter and intercept carbon deposits, making it easy to centrally process the carbon deposits.

[0037] The upper part of the protective box 27 is fixedly equipped with a jet pipe 38. The input end of the jet pipe 38 is connected to the output end of the fan 39. The fan 39 is installed on the upper part of the protective box 27. When the sandblasting gun body 30 is working, the output end of the fan 39 delivers gas into the jet pipe 38. The gas carries sand and dust into the collection box 42, thereby reducing the scattering of sand.

[0038] The above embodiment discloses a carbon removal device for die-casting molds. When it is necessary to fix the mold body 29, the mold body 29 is placed on the upper end of the support plate 11, and several positioning seats 13 position the mold body 29. Then, the output end of the first electric cylinder 23 drives the push rod 21 to slide. The push rod 21 drives two limit frames 14 to slide through the connecting rod. At the same time, the first rack 15 meshes with the gear 16, and the gear 16 meshes with the second rack 17 to drive the other two limit frames 14 to slide, so that the four limit frames 14 fix the mold body 29. The control component 46 controls the first motor 26 to start. The output end of the first motor 26 drives the support plate 11 to rotate at a fixed angle, so that the surface of the mold body 29 to be cleaned is aligned with the output end of the sandblasting gun body 30. The sandblasting gun body 30 uses high-speed sprayed sand particles to impact the mold surface and remove the carbon layer by physical impact force. Then, the sand and carbon blocks enter the collection box 42 through the collection hood 40. The screening screen 45 facilitates the filtering and interception of carbon blocks, making it easy to centrally process the carbon blocks.

[0039] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
