Description

Technical Field

[0001] This utility model relates to the field of casting technology, and specifically discloses a casting mold for a bearing sealing cover. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. To ensure their long-term effectiveness, a sealing cover needs to be installed on their side to prevent external dust, moisture, and metal particles from entering, thereby reducing internal wear and extending their service life.

[0003] In the existing technology, the casting molds used for casting bearing seal covers often produce porosity defects in the upper part of the castings and shrinkage cavities inside, resulting in a low product qualification rate and failing to meet the production needs of enterprises.

[0004] To address the aforementioned problems, this application discloses a bearing seal cover casting mold. Utility Model Content

The casting model includes an inner mold, an outer mold, a first core, a second core, and a third core. The first core is disposed on the upper surface of the outer mold, the second core is disposed on one side of the bottom of the outer mold, and the third core is disposed inside the inner mold. The inner mold is integrally connected to the inside of the outer mold and together with the outer mold, the first core, the second core, and the third core, forms a cavity for casting a bearing seal cover. The gating system is connected to the outer mold and is used to inject low-temperature ductile iron molten iron into the cavity; The first and third cores are equipped with a first air pipe.

[0007] More preferably, the gating system is connected to two casting molds.

[0008] More preferably, the gating system includes a hidden riser, a sprue, and two ingates, wherein the sprue is connected to the hidden riser, and the two ingates respectively connect the outer molds of the two casting models to the hidden riser.

Example

[0018] To address the issues of frequent porosity defects in the upper part of bearing seal covers formed by casting molds in existing technologies, as well as shrinkage cavities inside, resulting in low product yield, this paper refers to... Figure 1 and Figure 2 As shown, this application discloses a bearing seal cover casting mold, including two casting models 10 and a gating system 20 connected to the two casting models 10. The casting model 10 includes an inner mold 12, an outer mold 11, a first core 13, a second core 14 and a third core 15. The first core 13 is disposed on the upper surface of the outer mold 11, the second core 14 is disposed on one side of the bottom of the outer mold 11, and the third core 15 is disposed inside the inner mold 12. The inner mold 12 is integrally connected to the inside of the outer mold 11 and together with the outer mold 11, the first core 13, the second core 14 and the third core 15, forms a cavity (not shown) for casting the bearing seal cover. The gating system 20 is connected to the outer mold 11 for injecting low-temperature ductile iron molten iron into the cavity. The gating system 20 includes a blind riser 21, a sprue 22 and two ingates 23. The sprue 22 is connected to the blind riser 21, and the two ingates 23 respectively connect the outer mold 11 of the two casting models 10 to the blind riser 21.

[0019] First air pipes 16 are installed on the first core 13 and the third core 15, several second air pipes 17 are connected to the outer mold 11, and several third air pipes 18 are connected to the inner mold 12.

[0020] Based on the above structure, in specific implementation, the casting model 10 is first manufactured, and the first core 13, the second core 14, and the third core 15 are installed with the casting model 10 and then assembled. During the manufacturing of the casting model 10, the first air pipe 16, the second air pipe 17, and the third air pipe 18 are arranged in the set positions. After that, low-temperature ductile iron molten iron is poured into the sprue 22. During this process, the low-temperature ductile iron molten iron enters the dark riser 21 through the sprue 22 and then enters the cavities of the two casting models 10 through the two inner flow channels in sequence. After the low-temperature ductile iron molten iron is poured and after a set time, the bearing sealing cover can be cast. During the casting process, the first air pipe 16, the second air pipe 17, and the third air pipe 18 can enhance the exhaust. The core is heated and will release gas, so that the upper part of the casting will not have porosity defects and be scrapped. The gating system 20 can ensure the feeding of the casting and prevent leakage from shrinkage cavities inside the casting.

[0021] Based on casting requirements, the casting model 10 of this application includes two first cores 13. The two first cores 13 are arranged opposite to each other on opposite sides of the outer mold 11 and cooperate with the inner mold 12. In specific implementation, the two first cores 13, the second core 14 and the third core 15 together form a cavity for casting the bearing sealing cover.
