Description

Technical Field

[0001] The invention relates to the technical field of machining machine tool structures, and in particular to an efficient mold machining machine tool and a machining method. Background Art

[0002] Machine tools refer to machines used to manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. They are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. There are many ways to process mechanical parts in modern machinery manufacturing: in addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, all parts with high precision requirements and fine surface roughness requirements generally need to be processed on machine tools by cutting methods.

[0003] Moulds are various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, moulds are tools used to make shaped objects. This tool is composed of various parts, and different moulds are composed of different parts.

[0004] The existing patent CN202022819343.4 discloses a mold processing work platform that is easy to adjust for mold processing, including an installation box, the four corners of the bottom of the installation box are fixedly connected to support columns, the bottom of the support columns is fixedly connected to a movable plate, the surface of the movable plate is provided with a support sleeve, the bottom embedded in the support sleeve is fixedly connected to a spring, and the top of the spring is fixedly connected to the movable plate.

[0005] The mold processing work platform has the advantage of being easy to adjust through the coordination of various components, which solves the problem that the mold processing workbench is not convenient for adjusting the mold. When the mold position needs to be adjusted, the mold often needs to be removed for adjustment and fixed again after the adjustment, which increases the workload of the staff and reduces the processing efficiency. However, it still has the problem of limited adjustment height and some structures, such as the turntable structure, still need manual adjustment, which has the problem of low efficiency.

[0006] The existing patent CN116038354B discloses a CNC machine tool for turning, grinding and milling composite processing, in which a drilling tool is inserted into one side of the driving shaft head, and a linkage processing mechanism is arranged at one side of the outer wall of the drilling tool. The linkage processing assembly includes a milling cutter on one side of the outer wall of the drilling tool, and a grinding cutter is arranged at the other side of the outer wall of the drilling tool. The workpiece can be ground and milled over a large area without the need for a tool change process. However, the relative positions of the milling cutter and the grinding cutter in this patent cannot be changed, and the processing is relatively limited.
