Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a ceramic core cleaning device that is easy to use. Background Art

[0002] Ceramic core is a special material used in investment casting process, mainly used to form the inner cavity structure of casting. Its main function is to ensure the dimensional accuracy requirements of the casting for the cavity together with the outer mold and the mold shell. Ceramic core is widely used in the manufacture of cavities of castings with complex shapes or difficult to form due to its excellent properties, such as good yield dissolution, good chemical stability and high temperature resistance, good air permeability, low thermal expansion coefficient, easy molding, consistent dimensional accuracy and smooth surface, etc., in order to simplify the process difficulty, reduce costs and improve the qualified rate of products. Since the surface of the ceramic core is easily sintered with the filler used for baking during high temperature baking, resulting in sand sticking, the staff will need to grind the ceramic core to remove the attached filler.

[0003] After searching, the patent publication number CN217342482U discloses a surface cleaning device for a ceramic core, which belongs to the field of ceramic core processing technology. The key points of its technical solution include two fixed plates, and the two fixed plates are provided with a slot on the opposite side. Two clamping plates distributed up and down are arranged inside the two slots. A support plate with a central opening is installed on the upper end surface of the device body, and a plurality of second positioning blocks are installed on the left and right sides of the upper end surface of the support plate. The ceramic core to be cleaned is placed between the two clamping plates in the slot, and the clamping plate is squeezed according to the thickness of the ceramic workpiece, so that the clamping plate is forced to squeeze the spring until the ceramic workpiece is completely placed between the clamping plates, and at the same time, the lower end surface of the ceramic workpiece is in contact with the second positioning block on the support plate, and the positioning of the ceramic workpiece is achieved by the second positioning block, so that the ceramic workpiece can be clamped stably and stable cleaning can be achieved, thereby improving the cleaning quality and efficiency.

[0004] However, this patent still has some shortcomings. In actual use, this patent requires manual adjustment of the pressure plate to position and fix the ceramic core. The operation steps are cumbersome and time-consuming, and it is not convenient to use. The pressure plate can easily block the top of the ceramic core, affecting the cleaning process. At the same time, the position of the cleaning head in this patent cannot be adjusted. Therefore, during the cleaning process, the staff needs to repeatedly disassemble and assemble the ceramic core to adjust the position of the ceramic core in the fixed assembly for cleaning and polishing. The operation steps are cumbersome and time-consuming, which can easily affect the cleaning efficiency.

[0005] For this purpose, we propose a ceramic core cleaning device which is easy to use. Utility Model Content
