Description of the Invention: [Technical Field] The present invention relates to rapid molding technology, and particularly relates to spraying a spray coating on a surface of a mold by using a low-solubility resin to rapidly form a metal and a resin. Rapid film molding method for film coating. [Previous Technology] The conventional molding method is as shown in the first and second figures, a mold box (1), the mold box (1) is an opening upward facing a box, and the mold box has a bottom plate (2) a number of side plates (3) surrounding the bottom plate (2) to form a box. Λ One placement (4): First place a model (5) in the mold box (1). 0 Fill in (6): Fill a mold stone (7) into the mold box ( 1), the molding sand (7) is overlaid on the mold (5) and extruded to fill the mold sand (7) in the mold box (1). Upon completion (8): After the molding sand (7) is dried, the mold box (1) can be removed, and the mold (5) is taken out to form a mold. However, in the conventional molding method, 'the mold (1) is only covered with the mold sand (7) on the mold (5), and it is necessary to perform the pressing action at the time of covering to avoid voids. If it occurs, it will affect the mold sand (7) collapse when the mold is molded or the void will be generated on the surface of the model (5), which will affect the model (5) when it is later molded. In the conventional molding method, since only the molding sand (7) is used to cover the model (5), the bonding strength of the entire mold is insufficient, and some corners are very easy to inadvertently collide when taking the mold. In the corner, the corner 201233464 r collapses. The inventor of the present invention has this invention, which is based on the spirit of creation, thinking of different technical methods, and improving the present invention. SUMMARY OF THE INVENTION The conventional molding method, because only the metal resin is used to cover the mold, 'the joint strength of the whole mold is insufficient, and when the pressing action is not correct, there will be voids and some corners in the mold taking. The time will collapse _ 相 ' 'In addition' metal resin mold surface heat dissipation is poor, and the injection mold opening time is too long, the industry is not willing to use. The main object of the present invention is to spray a low-melting metal and a resin on a surface of a model by spraying a layer to rapidly form a film of a plurality of layers of low-soluble metal and resin, and to increase the bonding strength of the entire mold. It can prevent some corners from collapsing and damaging when taking the mold; in addition, since the heat transfer characteristics of the low-melting metal are much better than the surface of the metal resin mold, it is greatly helpful for shortening the injection time of the mold. In order to achieve the above object, the present invention provides a resin and metal composite spray rapid molding method, which comprises: a mold box having an opening facing upward phase body. The mold box has a bottom plate and a plurality of side plates, the side plate Surrounded by the bottom plate. One placement: First place a model in the bottom of the mold box. A spray coating: super-melting metal and resin are superposed on each other. Sprayed on the mold and combined to form a thin layer of a composite mold having a thickness of about 2 mm. Once filled in, a mixture of a premixed metal powder and a resin is further filled in the mold box, and the mixture is filled and coated to bond the sprayed layer. Finish: the mixture to be filled is hardened. The mold box can be disassembled and the model removed to form an injection mold with 4 201233464 heat dissipation, high precision and fast production. [Embodiment] In order to further understand the structure and operation of the present invention, that is, the intended effect, the preferred embodiments are described in detail below with reference to the drawings, and the objects, features and other features of the present invention are believed to be This can be an in-depth and specific understanding. Please refer to the third to fourth figures. The present invention relates to a resin and metal composite spraying rapid molding method, which comprises: a mold box (1 0 ), the mold box (1 〇) is an opening upward facing a box The mold box (1 〇) has a bottom plate (1 1 ) and a plurality of side plates (1 2 ), and the side plates (12) surround the bottom plate (11) to form a box. One placement (2 0 ): First place a model (2 1) in the bottom layer of the mold box (1 0), that is, place the model (2 i) on the bottom position of the bottom plate (丄 1). Spraying (30): spraying a layer of low-melting metal and resin on top of each other on the model (2 1), namely a layer of low-melting metal, a layer of resin, a layer of low-melting metal, and a layer of resin. And forming a sprayed layer (3 1 ) having a thickness of about 2 mm, wherein the low-melting metal and the resin are superposed on each other, and the low-melting metal can be mutually adhered by the cohesiveness of the resin material, and The surface of the model (2 1 ) is formed by copying the contour of the model (2 1), and the low-refined metal is granular, and the surface of the model (2 1 ) can be quickly formed and copied. The film is that the sprayed layer (3 1 )' has the advantage of increasing the bonding strength of the entire mold by using a plurality of layers of film, and prevents some corners from collapsing and damaging when the mold is taken. Filling in (4 0 ): mixing a premixed metal powder with a resin 201233464 (4 1 ) is filled in the mold box, and the mixture is filled and coated with the sprayed layer (31). Once completed (5 0 ): the mixture to be filled (4 1 ) and combined with the sprayed layer (31), the mold box (i 〇) can be disassembled, and the 槔 type (2 1 ) is taken out, that is, Excellent heat dissipation, high precision and fast shooting mold. The above is an overview of the manufacturing flow chart and the interconnection relationship of the present invention; then, the manufacturing process of the present invention can be combined with the expected performance of the rotating machine as follows: Please refer to the third to fourth figures, and Referring to the jade figure, the manufacturing process of the present invention described above can be implemented with a rotating machine (6 〇), which can be placed on the rotating machine (6 〇), the rotating machine (60) Is a machine having a driving element (61), the rotating machine (60) is provided with a rotating shaft (6 2 ), and the rotating shaft (6 2 ) is provided with a rotating disk (63) β 3 ) can be placed in at least one of the mold boxes (10). When using β ', put the empty mold box (i 〇) on the side of the rotating disc (6 3), and place the model (21) in the mold box (丄〇), and then start the Rotating the machine table (60), rotating the rotating plate (6), rotating the mold box (10) to the other side, performing the spraying (30), and filling the original side (4 0) The empty mold box can be re-applied (the manufacturing process, so that the rotating machine can be used without interruption.
