In particular, the 'rotating device 14 provided by the present invention, in the preferred embodiment, is designed to be connected to the mold in the mold device ,), and can be rotated by the plane rotation of the rotating device 丨4. The liquid mixture is uniformly distributed in the cavity of the mold (4), so as to avoid the viscousness of the mixture 20 1270451, the dead angle is not enough to fill, or the bubbles in the mixture remain, so the use of the present invention is provided. The molding equipment and the molding method can further improve the production yield, and the description of the characteristics and form of the mold will be further described later. In a preferred embodiment of the present invention, a molding method is specifically proposed to make it easier to manufacture a metal resin or the like and to reduce the damage of the mount for mounting the mold apparatus. 10 15 As shown in the third drawing, the molding method is to carry out a corpse treatment step 3 1 to mix the hardener, the resin and the metal powder, etc., to form a mixture. Thereafter, the mixture of the ingredients is passed through a heating step 32 to bring it into a liquid state' while heating. In a preferred embodiment, a liquid mixture can be subjected to a vacuum treatment step 33. The purpose of placing the mixed person in a vacuum environment is to remove the air bubbles from the liquid mixture. In the preferred embodiment, the present invention utilizes a true* heating furnace at the -heating temperature range. CM2Gt, and preferably: the heating temperature is 85 ° C, that is, after the Japanese 1 K 1 乂 heating the mixture for about 3-5 minutes, the color change to the mixture, ^ the pulverization in the mixed solution under the real pressure After being removed from the day, you can proceed to the next step. + 1 1 'The bubble has been removed and the liquid mixture is subjected to a molding process. This step is mainly accomplished by the combination of the injection process step 341 and the one rotation = step: 342. In the process of the prayer mode, it can be equipped with two = empty treatment 'the pressure in the cavity in the mold used::: Close to the vacuum state, to attract and exclude the remaining bubbles in the mixture injected into the cavity, to lower the prayer The probability of bubble generation during molding is 20 1270451, which helps to flatten the surface of the metal resin article. The rotation processing step 342 is mainly to rotate the mold of the material mold device _ by the above-mentioned rotation start, so as to quickly distribute the liquid mixture in the hole in the time of the pole, after the mixture is cooled and solidified. And can be set by the mold _ take metal resin products. In a preferred embodiment the invention is rotated ==. 〇 to 12. . The rotation speed of the revolution/minute (rpm) causes the prayer mode device 10 to rotate with it. Thereafter, a sintering treatment step 35 can also be used to increase the melting of the material in the metal resin 10 article to enhance its toughness and strength. Of course, a plurality of post-processing steps 36, such as a bake process step 36i, a mold release process step 362, an electric discharge process step 363, and a surface finish process step 364, etc., may also be further implemented in the present invention. The fourth figure is a schematic diagram for manufacturing a mold such as a rim in the second embodiment. Clearly, the mold 15 provided in the present invention has a closed cavity 151 for forming a wheel. The inner cavity of the circle is divided into an inner ring groove 153 and an outer ring groove 154, and is communicated with the groove 155 for accommodating the six rods, so that the inner ring groove 153 is slightly away from the central pivot position. Three injection ports 150 are formed in advance to be communicated to the cavity 151 and are radially symmetrical with each other. In addition, in the adjacent six connection bar channels 155, the mold 15 is also formed with at least three injection ports 15 〇 For the purpose of feeding, the exhaust port 152 is formed near the outer ring groove 154. In the fifth figure, a mold 16 for forming an artificial bone is also illustrated. Similarly, the mold 16 is formed with an injection port 16 邻近 at a position away from the cavity 161 and slightly away from the axis 166 of the central pivot 10 1270451 for feeding, and also has an exhaust port 162 formed away from the central pivot 166. . ^ The above-mentioned mold 15 or the pivots 156, 166 of the mold 16 for rotation are preferably located at the center of the center of the mold 15, 16, so that the mixture into the mold 5 can be immediately subjected to the mold 丨5, 丨6 Centrifugal rotation, the injection ports 150, 160 need to be placed at least slightly away from the central pivots 156, 166 of the molds 15, 16. On the other hand, the cavity 15 161 is evacuated through the exhaust gases Z B2, 162, so that the cavity 151, 161 can reach a low pressure, even reaching the vacuum state as described above, not only promoting the bubble release originally existing in the mixture. At the same time, the mixture is attracted to the cavity 丨5丨, and the upper 6 work has not yet filled the empty space. The animal can be easily understood by those skilled in the art, and the above apparatus can also be adapted to form a product other than the other metal resin, and constitute a kind of injection into the i. The difference from the metal resin molding method described above is that not all high-viscosity curable fluids can be obtained by mixing and heating processes, but as mentioned above, due to their high viscosity, they are generally not monthly.获得 Get a good molded product by casting. Therefore, after obtaining a high-viscosity curable fluid, it is only necessary to continue to exhaust the mold cavity as described in the foregoing method, and continue to rotate the mold along a pivot, and inject from the mold, the main inlet The fluid, by means of the exhaust gas, maintains the low pressure in the cavity, even the vacuum L, to eliminate the mixed bubbles in the fluid, while attracting the fluid to flow into the unfilled voids of the die eight, and by rotating the mold rapidly, i. The high-viscosity fluid entering the wedge hole is centrifugally forced to flow away from the drag axis. Thus, the highly viscous curable flow 11 1270451 body can be evenly filled inside the cavity. In summary, the invention is made up of η ^ dust square and its molding equipment, which is a fine-curing method to make a metal tree-like curable fluid product can quickly become a viscous ice into each serge I Day 1 molding Aachen its product yield, so 隹贝月匕 reached the purpose of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is limited to the simple equivalent changes and modifications made by the present invention and the contents of the invention.
