Description of the Invention: • Technical Field to Be Invented by the Invention The present invention relates to a "metal resin mold forming method" which utilizes a liquid resin to be infiltrated by a large gap of a metal block to be subjected to vacuum pressure. The pressing force # is sufficient to continuously penetrate the secret of the human powder and indeed fill the gap between the metal block and the powder to obtain a more uniform and higher cost. The size of the metal resin mold can be accurately controlled and prevented. Unexpected problems, and then the best use of no error, no shrinkage deformation. 6 [Prior Art] According to the general method of making low-point metal rapid molds, the principle of application is firstly applied. First, the low-melting point metal is heated and melted, and then the molten metal is directly poured into the plaster mold shell mold. After the metal job cooling and smelting to complete the rapid production of molds, the main disadvantages of such metal mold making methods include: (1) gypsum or ceramic molds will shrink and deform during the conversion process. (2) Pound-making operation Due to the cooling and cooling of the material, the cooling design device is installed, and the technology can not achieve complete uniform cooling, which leads to stress concentration and deformation. (3) The molding time is long and the benefit is low. The mold is turned into a book, and the gypsum conversion is about 2 days. The pottery mold is about 3 to 5 days. In addition to the above-mentioned rapid production technology of low melting point metal molds, another metal resin rapid mold is cured by resin-bonded powder. This technology can solve the problem of medium and small mold manufacturing technology and avoid the problem of open electric processing. In other words, in the process of injecting the aluminum powder into the cavity, the three faces of the aluminum powder and the dead corner of the cavity cause the turbulence phenomenon caused by the charging and the turbulence phenomenon, which cannot be surely placed in the cavity, and the aluminum powder is pressed. The density is not uniform, once it is limited by the stickiness of the resin. The knot force will shrink and deform, resulting in the disadvantage of poor precision. When the mold is taken, the corner of the mold will be derivatized when the density of the aluminum powder is not uniform. The trouble of not being able to accurately control the size. The present inventors have continually tested the process methods and products in the spirit of creation, in the spirit of creation, and in the creation of methods and installation methods. Through numerous experiments and years of experience, the present invention has been improved. The present invention has been further proposed. SUMMARY OF THE INVENTION The main object of the present invention is to provide a metal resin mold forming method which utilizes a liquid resin to penetrate from a large gap of a metal block so that the pressing force generated under vacuum pressure is sufficient to continuously penetrate into the powder. The smaller slits are thin and do fill the gaps left between the metal block and the powder to obtain a more uniform and higher density, so that the size of the metal resin mold can be accurately controlled and the problem of blowdown is prevented, thereby achieving error-free, Best for no shrinkage deformation ©© usage status. [Embodiment] The following is a detailed description of the preferred embodiment of the present invention, and the details and details of the program of the present invention are as follows: As shown in the first figure, it is a block diagram of the present invention (please refer to the second figure at the same time) The figure is a three-dimensional flow chart of the present invention, and the steps of the molding method are as follows: 6 201012619 首先 First, the 3D mold drawing is drawn by the computer software and the prototype mold is quickly formed by the prototype machine; And coating the plastic mold (10) with a mold cavity (11); C. taking out the rubber mold (1〇), each frame surface in the mold cavity (11) of the silicone mold (10) After injecting powder (21, which can be set as metal powder or ceramic powder) to a suitable height, place a number of metal blocks (22 ' can be set as a ball or aluminum sheet) above the powder (21) to the cavity (U). Filling; & D. Putting the plastic mold (1〇) filled with the powder (21) and the metal block (22) into a high-vacuum casting machine, and then injecting the liquid resin (23) into the cavity (11). The liquid resin (23) is completely defoamed by a vacuum machine using a helium vacuum machine, and the liquid resin is made under vacuum pressure. 23) It can be surely filled with the gap between the powder (21) and the metal block (22) to fill the cavity (丨丨) of the silicone mold (10) and form a metal resin mold through a high vacuum mold machine (2〇 , as shown in the third figure); thereby, the liquid resin (23) can be quickly infiltrated by the large slit of the metal block (22) under vacuum pressure to generate a large pressing force to increase the powder (21). The density is more uniform' and the liquid resin (23) is infiltrated by the larger gap of the metal block (22) so that the pressing force is sufficient to continuously penetrate into the small slit of the powder (21) and the disc is filled with the metal block ( 22) The gap left between the powder (21) to obtain a more uniform and higher density, so that the size of the metal resin mold (2〇) can be accurately controlled and the problem of blowout is prevented, thereby achieving no error, no The best use of shrinkage deformation. In summary, when the invention is industrially usable and progressive, and the invention is not found in any publication, it is also novel, and when it complies with the provisions of Articles 21 and 22 of the Patent Law, To file a patent for invention, please ask the reviewer to pay for the patent. 7 201012619 The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto; that is, the equal variation and modification of the scope of the patent application of the present invention should remain The scope of the invention is covered.
