However, the existing SLM equipment currently on the market has not proposed an effective mold grafting device for the mold. When the traditional SLM equipment processes parts, the parts directly grow on the substrate and the substrate is finally a whole. After the processing is completed, the electric saw can be used or wire cutting and other methods of cutting and separation

Embodiment Construction
[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] A kind of grafting device of SLM equipment forming mold of the present invention, such as figure 1 and figure 2 As shown, including the graft base material 1, the bottom surface of the graft base material 1 is positioned and fixed on the processing platform 5 by the positioning pin 2 and the fastening screw A6, and the surface of the graft base material 1 is fixed on the mold by the positioning hole pin 4 and the fastening screw B7 Base 3.
[0033] There are two cylindrical pin holes on the edge of the surface of the grafting substrate 1, and a positioning pin 2 is inserted into each cylindrical pin hole for positioning with the SLM equipment processing platform 5, and the other three corners of the edge of the grafting substrate 1 are fastened by fastening screws A6 is fixed on the processing platform 5 .

The invention discloses a grafting device for an SLM equipment forming mold. The grafting device comprises a grafting base material, the bottom surface of the grafting base material is fixed on a processing platform through a positioning pin and a fastening screw A, and the surface of the grafting base material is fixed to a mold base through a positioning hole pin and a fastening screw B. An array type positioning pin hole is adopted in the grafting base material so as to increase the general applicability; the overall rotation of all the array type positioning pin holes in the grafting basematerial is 5-30 degrees, and the preprocessing difficulty of the SLM model is reduced; and the grafting base material still uses a screw fixing mode, the heat deformation caused by heat transfer in the printing process of the grafting base material is reduced, and the precision of the grafting printing of the mold is indirectly guaranteed. The invention further discloses a grafting method using the grafting device. The grafting method is simple to operate, the processing process is combined with a material additive and a material reducing mode, after the parts are printed, the whole mold is taken down from a grafting substrate and does not need to be cut and separated.
Description
technical field [0001] The invention belongs to the technical field of additive manufacturing and processing, and in particular relates to a grafting device for a molding die of SLM equipment, and also relates to a grafting method using the grafting device. Background technique [0002] Mold is a tool for forcing metal or non-metal forming, and it is an essential key process assembly in industrial production. Parts produced in batches using molds have the advantages of high efficiency, high consistency, low energy consumption, high precision and high complexity, and are therefore widely used in machinery, electronics, automobiles, information and other industries. According to different processing objects and processing technology, molds can be divided into stamping molds, plastic molds, casting molds, forging molds, etc. [0003] Traditional molds are manufactured by using ordinary machine tools or CNC machine tools. When faced with molds with extremely complex internal st...
