Description of the Invention: [Technical Field of the Invention] The present invention is a method for manufacturing a high-density pattern mold, in particular, a processing method for engraving a mold inner molding path by using a laser processing machine to form a molded object The outer peripheral surface has a high-precision spaced arrangement of the grain structure, which increases the practicability of the molded article and enhances the decorative effect of the appearance of the shape itself. [Prior Art] With the development of _ _ evolution and innovation, the demand for exquisite appearance and structural precision of various types of production and impact is increasing, so for computers, communications, and hybrid electronics, The precision and refinement requirements of molding tools such as automotive products and enamel jewelry are getting higher and higher. Generally, when molding a mold, the precision and refinement of the forming mold are the most important, which is related to the cutting, cutting, drilling and other processing techniques. The processing methods of the traditional forming mold are mostly milling and etching. Processing and electrical discharge machining. Taking sharp-cutting processing as an example, it uses a shaped cutting tool to remove the material inside the mold in a rotary contact cutting mode under the control of computer parameters, but this processing method is affected by the size of the mold material and the processing tool. Moment, when the mold is to be formed into a small-sized object or the material of the processing mold is a super-hard alloy material, it is not easy to find a suitable cutting tool for machining by forming a mold by milling. The button engraving method is to etch the inside of the mold with an erosive chemical substance to make a molding groove with a matching object structure inside the mold, but 3 201020099 This method is not suitable for the large amount of material to be added to the jade, in addition, The procedure of J plus is too complicated and the processing size is difficult to control. The electric discharge machining method is that the cutting limbs and the rake poles are reduced to each other to generate an arc phenomenon, so that the mold (4) exhibits a high temperature state, and the surface of the mold is melted and evaporated. The silk force generated by the Wei Cai and the processing (4) contact surface will melt. Material removal, however, the mold forming rate of such electric discharge machining is slower and it is easy to produce secondary discharge, which affects the surface finish of the mold. Degree 'cannot make high-precision pattern structure on the mold surface. The laser processing system utilizes a focusing device to cause the laser beam to illuminate the surface of the object to cause the secret processing material to be vaporized. However, in the case of high processing precision of the mold of the age, the outer (four) structure of the mold is more complicated. In the process of the mold=row, during the firing and the calling, it is easy to cause the laser beam to be irradiated and the part is not completely melted, resulting in The machining precision of the mold surface is poor. SUMMARY OF THE INVENTION The main object of the present invention is to provide a method for manufacturing a high-density metric pattern mold, which is characterized by a computer secret to the surface of the object toward the longitudinal axis, and is processed by laser. The machine segments rotate the surface of the forming groove of the engraving mold, so that the surface of the forming groove of the mold core has a high-density texture, thereby improving the appearance decoration effect of the molded object after injection molding, and increasing the practicability of the molded object. In order to achieve the above object, the manufacturing method of the high-density pattern mold of the present invention comprises the following steps: forming a drawing of a molded object having a pattern structure on the outer peripheral surface by a computer system, wherein the pattern structure vertically corresponds to the shape of the formed object 4 201020099 T direction The direction of the axis; the surface pattern structure of the shaped object in the weicheng diagram is intercepted f, and according to the degree of fineness of the pattern structure, the knives that can be processed in the same plane are formed into blocks, and then the multi-component blocks are formed. Set as laser processing machine: & lion lion parameters; production - with _ slot Lai Ren and a matching mold position _, and then set Lai Ren in the fixture (10) fixed; apply laser processing machine, And the parameters of the segmentation _ are used to rotate the tool and the mold core to the processing angle of each of the ship blocks, and the laser beam is biased.
