Description

Technical Field

[0001] The utility model relates to a mould, in particular to a finishing mould for mineral castings, and belongs to the technical field of mineral casting processing. Background Art

[0002] The product of mineral casting is mineral casting, a future-oriented environmentally friendly material. As a structural component of a machine, it can replace traditional cast iron in some applications due to its price and performance advantages. Mineral castings have a thermal expansion coefficient similar to that of steel and can be well integrated with the materials cast into the mineral casting. The integration performance of mineral castings saves users a lot of assembly and machining time, greatly improving their production efficiency and economic benefits.

[0003] Its application number is "CN202322179104.0" disclosed in "A mineral casting mold easy-to-remove mold structure", which "comprises a base plate, a lower mold base is installed on the upper end of the base plate, a plurality of bolt seats are fixedly connected to the outer wall of the lower mold base, a bracket is fixedly connected to the outer wall of the base plate, and the bracket is connected to the upper mold base through a connecting mechanism, a device cavity is opened in the base plate, a plurality of bolt holes are opened in the upper end of the base plate, a plurality of the bolt holes are communicated with the device cavity, a plurality of the bolt holes are threadedly connected with screws, the screws are threadedly connected to the bolt seats, a first gear is rotatably connected in the device cavity, the first gear is connected to a connecting rod through a rotating mechanism, and the connecting rod is connected to the screw through a sliding mechanism." In the utility model, by setting the first gear, the second gear, the screw and other components, with the help of the meshing of the first gear and the second gear, the rotation of the first gear drives multiple screws to rotate synchronously and slide upward until they slide into the bolt seat. In this way, when the upper mold base and the lower mold base are disassembled and installed, multiple screws can be screwed in synchronously, ensuring tightening while reducing the installation and disassembly time.

[0004] However, the above method still has the following defects: multiple screws can be screwed in at the same time through the engagement of gears, which can realize the rapid installation and removal of the lower die base. However, due to the small diameter of the screws, it is difficult to align multiple screws with multiple bolt seats at the same time. The position of the lower die base needs to be adjusted, which requires high precision and is inconvenient to operate. Once the screws are offset, they are easily deformed and damaged, and it is difficult to ensure the positional accuracy between the upper die base and the lower die base. The upper die base is only supported by hydraulic cylinder oil and is easily offset, which will reduce the processing accuracy of mineral castings. Utility Model Content
