Description of the Invention: [Technical Field] The present invention relates to a rapid mold manufacturing method and a rapid mold, and more particularly to a rapid mold making and composite rapid mold using a high plasticity composite material. , [previous technology] The traditional traditional sheet metal molds are steel molds, mold steel embryos through the material extraction, stress release, wire cutting, discharge, grinding, polishing to the surface of the string, such as the strict pass to produce mold, development The time course is relatively long and costly. 'This is a new car test or maintenance spare parts, etc. There are a few small sample & parts products, the industry often chooses the rapid mold (also known as the temporary attack 2 = replace the permanent. ^ General fast Molds are distinguished by low melting point alloys or zinc alloys, cast iron molds, resin molds, electric scale molds and metal spray molds due to differences in materials and processes. The above-mentioned fast mold methods are not widely used in industry. It is as follows: the alloy with low melting point is wrong, and the alloy composed of tin and other metals is relatively expensive and requires heating equipment when used. Zinc alloy and prayer iron also need high temperature dissolution furnace to form a cast embryo, low solubility. When casting alloys, alloys and cast irons, it is necessary to complete the casting of the embryos and then recast the casting blanks into the mold surface into a mold; a cross-sectional view of the resin mold of the prior art according to Fig. 1 (4). The mold 10 is formed by mixing a resin, a hardener, and a filler, and then molding the mold core. For a mold of a large sheet metal part, the cost of applying the resin material is very high, resulting in a limited reduction in mold cost. 201023993 1 Therefore, 'the knowledge of gold Stamping rapid molds (such as low melting point alloys or zinc alloy 'gold, cast iron molds, resin molds, scale molds and metal spray molds, etc.) are relatively incapable of providing fast, economical and economical solutions for a small number of large sheet metal parts. There is still a lot of room for improvement in the application of the market demand. (4) The problem to be solved by the present invention is to provide a body part of a large area of a rapid mold which is used in the field of material preparation. And forming a composite material rapid hard mold manufacturing method and a composite material rapid mold by injecting a resin hardened layer on at least one surface of the sand mold. The technical means for solving the above process problem provides a composite material rapid mold manufacturing method, The step includes: molding a sand mold body, the mold body has a - surface - the first surface The model corresponds roughly to the surface shape of the workpiece prototype; a resin mold frame member is formed, and at least one positioning support member is disposed in the valley space of the resin mold busy member; the workpiece prototype is placed on the positioning support member; Positioning the sand mold body in the tree mold frame member, the first surface of the sand mold body is opposite to the workpiece prototype surface and maintaining a gap; and the resin mixture is filled in the resin mold frame In the space, a resin mixed material layer is formed on the first surface, and the composite material quick-release mold formed by hardening and bonding the resin mixture to the sand mold body is taken out. The technical means for solving the above product problem is provided by the present invention. A composite rapid mold comprising: a sand mold body having a first surface; and a resin mixed material layer formed on the first surface, the resin 201023993 mixed material layer forming a working surface. Shuming’s secret lies in the fact that Shu Mingzheng is a composite mold with a resin and sand mold as the main component and its process, resin material, high complex surface quality, good mold surface, internal filling of resin structure, high-temperature resistance Sand mold material for strength casting, low cost and good strength after high temperature sintering. Composite structure of resin and sand mold is applied to simple mold manufacturing of large complex curved surface products with shortened time history, high precision, good quality and economy. The advantages. β [Embodiment] A preferred embodiment of the present invention will be described in detail below with reference to the drawings. First, referring to Fig. 2, a flow chart of an embodiment of a composite rapid mold manufacturing method of the present invention and a schematic cross-sectional view of Fig. 3 to Fig. 3 (4) Fig. 2 are shown. In this embodiment, the manufacturing method comprises: (Step S100) molding a sand mold body 2, the sand mold body 2 has a first surface 22, preferably, the shape of the first surface 22 corresponds to a workpiece Prototype 30 surface modeling (as shown in Figure 3). The sand mold body 20 is made by a sintering process of a mixture of a sand-mixed water glass (Ν_〇3). The sintering process of the application is to introduce the strontium water glass mixture into a mold box and pass carbon dioxide (c〇2) gas to form a wet sand mold (the time of hardening into a wet sand mold varies with the size of the mold) Different, generally about 5 to 10 minutes, but not limited to this, the wet sand mold is placed in a sintered crucible and sintered at a maximum sintering temperature of 1 〇 5 〇〇 c for at least 2 hours. The size of the foundry sand of the above-mentioned enamel water glass mixture is 5 201023993 "22 S to 60 S, and the weight ratio of the water glass is 1% to 7% of the foundry sand. (Step S110) A resin mold frame member 40 is produced. The resin mold frame member 40 has an accommodating space 41 and a cover plate 42. The accommodating space 41 has at least one positioning support member 43. The positioning support member 43 can be mounted on the bottom surface of the accommodating space 41. Or on the side wall (as shown in Fig. 3B). (Step S120) The workpiece prototype 30 is placed on the positioning support member 43, and the working surface of the composite material rapid mold 60 is intended to be copied upward (Fig. 3B). (Step S130) Combine and position the sand mold body 20 in the resin mold frame member 40, and close the resin mold frame member 40 to the cover plate 42, the first surface 22 of the sand mold body 20. Opposite the surface of the workpiece prototype 30 and maintaining a gap 44, the gap 44 determines the thickness of the resin material covering the first surface 22. If the sand mold body 20 is not limited to the first surface 22, it is also intended to be included. Other surfaces of the sand mold body 20, such as the side or top surface, must be When the sand mold main body 20 is placed on the resin mold frame member 40, the distance between the surface of the sand mold main body 20 and the wall surface of the resin mold frame member 40 accommodating space 41 is reserved (as shown in Fig. 3C). A resin mixed liquid 50 is poured into the accommodating space 41 of the resin mold frame member 40 to form a resin mixed material layer 51 on the first surface 22. In order to prevent the resin mixed liquid 50 from filling during the filling process The bubble is generated, and the step is preferably performed in a vacuum process, and the vacuuming process is configured to dispose a vacuuming device 70 in the accommodating space 41 of the resin mold frame member 40 to make the resin mold frame member. 40 is formed into a vacuum box 6 201023993 (shown in FIG. 3D), and when the vacuum pressure in the vacuum chamber is less than 2 ^ Kg/cm 2 at atmospheric pressure, the resin mixture is poured into the resin. The liquid 50 is formed by mixing 100% by weight of the resin with 300% to 500% by weight of the additive, and then adding 5 to 1% by weight of a hardening agent. The weight additive may be iron powder. Filling of aluminum powder, glass fiber, ceramic powder or other reinforcing structures (Step S150) taking out the resin mixture liquid 5 〇 hardened and bonding to the composite material rapid mold 6〇 formed by the sand mold body (as shown in FIG. 3E), and the resin mixture 50 hardens with the mold size. However, the difference is generally about 5 to 40 minutes, but not limited thereto. When the surface of the workpiece prototype 30 is the outer surface of a rice part, the composite rapid mold 60 can be When the surface of the workpiece prototype 30 is the inner surface of a workpiece part, the composite rapid mold 60 may be a movable mold or a mold. _ In addition, in order to facilitate the smooth demolding of the composite rapid mold 60 after forming, the step of spraying the release agent is further included before or before the workpiece prototype 30 is disposed on the positioning support member in the resin mold frame member. The release agent is sprayed on the surface of the workpiece prototype 30 or the inner surface of the resin mold frame member 40. Referring to Figure 4, a cross-sectional view of an embodiment of the composite rapid mold embedding support frame of the present invention is illustrated. In order to obtain a better tensile strength of the sand mold body 20 after sintering, at least one support frame 21 may be further embedded in the sand water glass mixture. Of course, if the composite material rapid mold 60 201023993 is manufactured, the one end of the support frame body 21 which is embedded in the large mold can be outwardly extended to form a holding structure of the fixing bolt 211 for gripping and carrying. Referring again to Figure 5, the surface of the composite rapid mold of the present invention is shown. A cross-sectional view of a rough surface embodiment is shown. In the present embodiment, the joint surface of the sand mold main body 20 - and the resin mixed material layer 51 has a rough surface S shape of at least one score pattern to improve the bonding strength of the resin mixed material layer. Referring to FIG. 3E, the composite rapid mold embodiment of the present invention has a composite rapid mold 60 comprising: a sand mold body 20 having a first surface 22; and a resin mixed material layer 51 formed on the same. On the first surface 22, the resin mixed material layer 51 forms a working surface 61. The resin mixed material layer 51 is formed by mixing 1% by weight of a resin with 300% to 500% by weight of an additive, and then adding a 5% by weight to ι% by weight of a hardener, wherein the weight is added The material may be an additive of a reinforced structure such as iron powder, aluminum powder, glass fiber or ceramic powder.
