[0001] The utility model relates to the technical field of mineral castings, in particular to a mineral casting with enhanced compressive strength. Background Art

[0002] Mineral castings are cast at room temperature using molds, and complex structures can be formed in one go. As structural materials, mineral castings are constantly replacing traditional structural materials, and the key to their rapid development lies in mineral casting, molds, and stable bonding structures. Currently, mineral castings have been widely used in many machine tool fields such as grinders and high-speed machining.

[0003] Its application number "CN202020240927.3" discloses a "slide based on mineral casting", which "has a slide body and a bearing seat made of gray cast iron, a mineral casting is provided on the slide body, and the bearing seat is embedded in the upper end face of the mineral casting. Plug-ins are provided between the slide body and the mineral casting, and between the mineral casting and the bearing seat, respectively, for connecting the slide body, the mineral casting and the bearing seat into a whole during casting." In the utility model, the mineral structure slide formed by the organic combination of gray cast iron and minerals has better shock absorption effect and bending strength than traditional pure gray cast iron castings, which can reduce the impact of vibration on machine tools and equipment. The specific heat capacity of mineral castings is higher than that of cast iron, and the deformation due to heat is small. It is easy to form during casting, suitable for casting components with more complex structures, and can be used for the processing and production of movable parts of CNC machining equipment, thereby enabling mineral castings to be fully applied.

[0004] However, the above method also has the following defects: the bearing seat is embedded in the upper end face of the mineral casting, the contact area is small and the pressure is large. The pressure is directly transmitted to the mineral casting through the bearing seat, which can easily cause the contact surface of the embedded bearing seat to loosen and have poor pressure resistance, which will reduce the stability of the bearing seat. In addition, the bearing seat cannot be disassembled after being embedded and is difficult to replace if damaged. Utility Model Content
