Therefore, the labor cost is large. Another mold injection molding method is to firstly use the inner surface of the metal mold cavity to pre-set the pattern by using the remaining pattern, and then inject the plastic into the cavity, because the uniform sentence causes the plate to have bubbles or deformation, and the mold is shot (four) type , its processing plate size size New, no (four) drum _ mode = not _ sample demand of the board, that is, the need for higher cost of the metal two \ and another one on the glass mold, then pour the plastic into the mold Forming the plate, so first select 'line exposure, and then use the corrosion method to enter the position according to the exposure, but the corrosion can not be accurately controlled, the success rate is very low, the production is not in line with the production efficiency, and then ^, The danger of the production process of the moon and the early film production is ^ ^ ( 四 (4) glass mold, the edge is 'based on quality control, the actual technology has improved. [New content] The consideration of production efficiency and safety, so 5 M349323 in the second party = to solve the above problems and provide a kind of mold material and then prefabricated high, and (4) this 'provided - product _, The production effect is _ light guide secret production method. With the purpose of r, this creation is a model for manufacturing light guide plates; 3 Street: it is made of a glass material and has a lower surface, and the technology, processing preset patterns under the surface. The upper mold is made of glass material and has an upper surface, and the elastic member is located between the upper and lower molds, and forms: an enclosed space with the upper surface of the lower mold.俾 is used to inject the charge. The lower member is for fixing the elastic member to the upper mold and the clamping member' to hold the upper mold and the lower mold. The above and other objects and advantages of the present invention are readily apparent from the detailed description and drawings of the following selected examples. Of course, the present invention may be varied in some arrangements or arrangements of parts, but the selected embodiments are described in detail in the present specification and the construction thereof is shown in the drawings. = [Embodiment] M349323 Please refer to Fig. 1 to Fig. 3, which shows the structure of the embodiment selected for this creation. This is for illustrative purposes only and is not restricted by this structure in patent application. . The following is a description of an embodiment of the present invention, "Mold for manufacturing a light guide plate member", which comprises: a mold 1 comprising: an upper mold 1 1 , a lower mold 1 2, an elastic member 13 and a fixed Element 14 and a clamping element 15 are provided. The upper mold 11 has an upper surface 1 1 1 and a lower surface 1 1 2, and the lower mold 12 has an upper surface 1 2 1 and a lower surface 1 2 2, and the upper mold 1 1 and the lower mold 1 2 are Made of a glass material. At least one of the lower surface 1 1 2 of the upper mold 1 1 and the upper surface 1 2 1 of the lower mold 1 2 is processed by a sand blasting technique with a predetermined pattern, wherein the sand blasting technology uses the sanding system It is a kind of alumina, glass beads, tantalum carbide, gold steel sand, steel beads, copper beads, ceramic sand, aluminum sand, steel gravel, plastic sand, walnut sand, and the sandblasting technology utilizes high-speed jet particles, collision pre-processing One of the surfaces. The elastic member 13 is located between the upper mold 11 and the lower mold 12, and forms a closed space with the lower surface 1 1 2 of the upper mold 1 1 and the upper surface 1 2 1 of the lower mold 1 2 . The crucible is supplied with the slurry 16 and the material of the elastic member 13 is a synthetic resin. The fixing member 14 is positioned on the upper surface 112 of the lower mold 1 2, and the fixing member 14 is a plurality of fixed lines. In addition, the fixing member 14 can also be positioned. The elastic member 13 is on the lower surface 1 1 2 of the upper M349323 mold 1 1 . The clamping member 15 is for holding the upper mold 1 1 and the lower mold 12, and the clamping member 15 is a plurality of G-shaped clips. In use, please continue to refer to the flow chart of FIG. 4, firstly, the slurry of the light guide plate is prepared and prepared in the preparation tank. The slurry 16 includes at least 50% by weight of decyl acrylate. Polymerized into a viscous liquid and added with * ' starter. After the slurry 16 is blended, the slurry is filtered by vacuum pressure to remove impurities. The filtered slurry 16 is formed by pouring into the mold 1 by casting, and the lower surface of the mold 1 1 and the lower mold 1 2 and the upper surface 1 2 1 are first A predetermined pattern of the film 1 1 3 is attached. Referring to FIG. 5, a plurality of high-speed particles are sprayed by a sand blasting machine, and each of the high-speed particles collides with the lower surface 112 and the upper surface 121, thereby improving The surface characteristics, and the different blasting sand diameter, sand blasting type, blasting sand time and sand blasting force can be used to control the depth of the impacted processing surface, which is the application of the physical collision principle, and the surface of each glass mold is preset. pattern. Since the surface of the glass is first processed by sand blasting, a light guide plate having a large size can be produced, and the processing is completed at one time, so that the cost and the production efficiency are superior to the conventional technology. After the lower surface 1 1 2 and the upper surface 1 2 1 are sandblasted to complete the preset pattern, the film 1 1 3 is removed, and the surface processing of the glass mold 1 is completed, and the film 1 is additionally processed. 1 3 can also be replaced by the gold 8 M349323 which is a preset pattern, which is a thin plate f 14 'Please refer to the 6th ®, which is a schematic diagram of the operation of the metal sheet in the second embodiment', so that the sandblasting method is adopted, by means of the metal, The plate 1 14 'forms each of the lower surface 2 and the upper surface 2 i to form a preset pattern. Next, each of the fixing members 14 is used to position the elastic member 丄3, and the elastic member 13 is drawn into a ring shape and fixed to the lower mold 丄 2, and the slewing member 1 is fixed elastic members 丨 3 Four (four) of the lower mold i 2 , whereby the elastic member; L 3 is spread to make it substantially square, and after the elastic member 13 is fixed, the upper member is covered, wherein the elastic member 1 3 ' is located between the upper mold χ χ and the lower mold i 2 , and the lower surface 1 1 2 of the upper mold 1 1 and the upper surface i 2 该 of the lower mold form a closed space. The slurry i 6 is then injected, and the elastic member 13 is made of a synthetic resin, and the shrinkage margin is absorbed after the slurry 6 is introduced into the mold. Continue to use a plurality of G-shaped clips 1 5, and clamp the three sides of the upper mold 1 1 and the lower mold mold 1 2 to re-spin the mold 1 so that the unfastened fourth side faces upward, please refer to the operation of FIG. 7 Schematic, and placing the injection piper 6 on the fourth side, and the slurry 丄6 is washed by the injection pipe 17, because the mold is made of glass material, and the filling can be observed during the process of washing the aggregate material 16. Progress and whether or not bubbles are formed. Then, the mold 1 is returned to the original horizontal position, and the fourth side is fastened by the G-shape, and then pressed to the upper mold, and the exhaust is finally exhausted. Finally, the same is completely fixed. The casting process of this embodiment is completed on the four sides of the upper mold 1 1 and the lower mold 1 2 . After the mold 1 is poured into the casting slurry 16 , a 25 is then placed.
