[0002] In the field of additive manufacturing, molds are key tools that determine the quality, precision, and production efficiency of castings. Traditional casting molds are typically manufactured using machining, casting, or forging combined with subsequent heat treatment.

[0006] Identify parameters of each block part;

[0007] Arrange the marked parts according to preset rules to make full use of the board area;

[0008] Output the processing program according to the typesetting results with the mark, and import it into the CNC machine tool to cut the plate;

[0009] The cut parts are assembled according to the markings to form a mold.

[0010] In one embodiment, when the mold is divided into blocks in three-dimensional software, the mold is divided into several layers of equal thickness or several layers of unequal thickness according to the structural characteristics of the mold.

[0011] In one embodiment, the mold is parameter-identified layer by layer, and in each layer, a plurality of sub-parts of the layer are parameter-identified one by one in sequence.

[0014] In one embodiment, the preset rules for typesetting in the three-dimensional software also include: reserving cutting spacing between adjacent block parts.

[0015] In one embodiment, the preset rules for typesetting in the three-dimensional software also include: reserving a processing allowance for each block part for removing or trimming defects such as burrs after subsequent cutting.

[0016] In one embodiment, the preset rules for typesetting in the three-dimensional software also include: arranging the block parts of different thicknesses on the plates of corresponding thicknesses according to the thicknesses of the block parts.

[0017] The mold manufacturing method described above divides the mold into multiple components, optimizes their layout, cuts them, and then reassembles them into a complete unit. This method is capable of producing molds with large, complex, and irregularly shaped structures. The components are arranged according to preset rules, improving sheet metal utilization and reducing manufacturing costs. By labeling each component with parameters, they can be quickly assembled into a mold blank based on the identified parameters after cutting. Furthermore, the traceability of each component's information facilitates the rapid location and resolution of defective or problematic components, enabling iterative optimization of the manufacturing method for the same type of mold.

[0031] See Figures 1 to 5 One embodiment of the present invention provides a mold manufacturing method, comprising: dividing a mold 1 into several layers in 3D software, each layer into several sub-components 2; parameter-labeling 3 for each sub-component 2; layout-setting the labeled sub-components 2 according to preset rules to fully utilize the sheet material area; outputting a processing program based on the labeled layout results, and importing it into a CNC machine tool to cut the sheet material; and assembling the cut sub-components 2 according to the labels to form the mold 1. This mold manufacturing method divides the mold 1 into multiple sub-components 2, optimizes the layout, cuts them, and then assembles them into a whole. This method can be used to manufacture molds 1 with large, complex, and special-shaped structures. Layout-setting the sub-components 2 according to preset rules improves sheet material utilization and reduces manufacturing costs. By parameter-labeling 3 for each sub-component 2, the cut sub-components can be quickly assembled into a mold 1 blank according to the parameter labels 3. Furthermore, the information of each component is traceable, facilitating the rapid location and resolution of defective or problematic components, and enabling iterative optimization of the manufacturing method for the same type of mold.

[0032] Optionally, in one embodiment, the mold 1 is a wooden mold or a mold made of metal, composite material or the like.

[0033] Optionally, the mold manufacturing method further comprises the steps of: performing correction and surface finish treatment on the assembled mold blank to obtain the mold.

[0034] In one embodiment, when dividing the mold 1 in 3D software, the mold 1 is divided into layers of equal thickness or unequal thickness based on its structural characteristics. Alternatively, the mold 1 can be divided into layers of equal thickness based on the thickness of the plate. Differentiated layering can also be used for complex structures with variable cross-sections to improve accuracy. For regular structures, the number of layers can be reduced, saving steps and improving efficiency.

[0035] In one embodiment, a mold 1 is parameterized layer by layer 3, and within each layer, several sub-components 2 are parameterized and labeled sequentially. The sequential numbering within each layer corresponds to the physical location, facilitating rapid assembly after cutting. Furthermore, this system supports automation, providing ordered path planning data for robotic assembly.

[0036] like Figure 2 As shown, optionally, in one embodiment, when parameter identification 3 is performed on the segmented parts 2, each segmented part 2 is parameter identified 3 according to the numbering method of "part number-layer number-specific position number". For example, the parameter identification 3 of a segmented part 2 is J0-01-06, which means the sixth segmented part in the first layer of the J0 component.

[0037] In one embodiment, the feature is that the preset rules for typesetting in the three-dimensional software include: typesetting in the order of the outline size of the block parts 2, and arranging the block parts 2 with smaller outlines in the blank space of the layout to fully utilize the board area. Figure 3-Figure 5 The result of the arranged layout is shown. The block parts 2 with different outline sizes are arranged in descending order, with larger parts arranged first and then smaller parts arranged.

[0038] In one embodiment, the pre-set rules for layout in 3D software also include: reserving a cutting distance between adjacent segmented parts 2. This prevents the contours of different segmented parts 2 from interfering with each other during cutting, ensuring dimensional compliance. The cutting distance should not be too large; it should only be large enough to accommodate the cutting tool size, thereby reducing material waste.

[0039] In one embodiment, the preset rules for typesetting in the three-dimensional software also include: reserving a processing allowance for each block part 2 for removing or trimming defects such as burrs after subsequent cutting.

[0040] In one embodiment, the preset rules for typesetting in the three-dimensional software further include: arranging the segmented parts 2 of different thicknesses on plates of corresponding thicknesses according to the thickness of the segmented parts 2. Optionally, as Figure 3-Figure 5 As shown, different sub-parts 2 are arranged on the first plate 4, the second plate 5, and the third plate 6, respectively, so that parts of the same thickness can be processed together, reducing the number of tool changes on the machine tool and the working time per piece. At the same time, it avoids material waste caused by processing thin parts on thick plates, saving plate costs.

[0041] The above-mentioned mold manufacturing method divides the mold 1 into multiple block parts 2, optimizes the layout, cuts them out, and then splices them into a whole. This can realize the production of molds 1 with large, complex and special-shaped structures. The block parts 2 are arranged according to preset rules, which improves the utilization rate of the plate and saves manufacturing costs. By parameterizing each block part 2 3, it is convenient to quickly splice and assemble the mold 1 blank according to the parameter identification 3 after cutting. At the same time, the information of each part is traceable, which facilitates the rapid location and processing of defective or problematic parts, and completes the optimization and iteration of the manufacturing method of the same type of mold 1.

[0042] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
