Description

Technical Field

[0001] The utility model belongs to the technical field of large die set grinding, and in particular relates to equipment for pre-treating the bottom surface of a large die set mold shell of a single crystal casting. Background Art

[0002] The bottom surface treatment of the mold shell is a pre-processing method for the bottom surface treatment of the membrane shell. Its main function is to grind the bottom of the mold shell flat and place it on the water-cooled chassis of the directional solidification furnace, and then rise into the heating body. As the mold shell is heated to the specified temperature, the melted alloy will be poured into the mold shell. At this time, the mold shell is in close contact with the water-cooled chassis, so that the molten alloy directly condenses after encountering the water-cooled chassis, forming a temperature gradient. If the bottom of the mold shell is uneven, the bottom of the membrane shell cannot be in close contact with the water-cooled chassis, which will cause the poured alloy solution to flow out along the uneven place, causing the mold shell to drift or tilt, resulting in the mold shell being unable to be filled with the melt and causing the experiment to fail. The oozing molten metal will also encounter the surface of the furnace body and condense instantly and directly adhere to the furnace wall, making it difficult to clean or even damaging the furnace wall and causing an accident. Therefore, the treatment of the bottom surface of the mold shell is an urgent problem that needs to be solved.

[0003] During operation, the existing large-module membrane shell equipment has a too large bottom grinding wheel and a gap in the middle, which makes it inconvenient to grind the large-module shell, and the middle area cannot be ground in place, resulting in difficulty in processing the middle area of ​​the large-module shell. Due to the large size and heavy weight of the large-module shell, when the wax film shell is coated with slurry and sand, the bottom disc edge of the wax film will be warped and deformed, resulting in an uneven bottom surface of the shell, which directly affects the bottom grinding of the large-module shell. At least two people are required to cooperate with each other to complete the grinding. The manual operation process not only reduces work efficiency, but also generates a large amount of dust, polluting the surrounding environment and causing dust hazards to the staff. Summary of the invention

[0004] In order to solve the deficiencies in the prior art, the utility model provides a single crystal casting large module shell bottom surface pretreatment equipment, which realizes circular motion by turning on the diamond cloth of the turntable through a servo motor to grind the large module shell multiple times, and the dust generated during the grinding process is sucked in through the dust removal port of the dust collecting plate. After a certain amount of dust is collected, the dust can be cleaned together, which not only improves the grinding efficiency, but also saves labor costs and time costs, thereby ensuring the grinding yield.
