分を変えて強度向上を計ろうとしている。(Prior art) Zinc-based alloys have excellent castability and transferability, and resin molds can be completely manufactured by casting, which has the advantage of greatly reducing the machining process. Although it is widely used as a mold for prototype products, it has the disadvantage of poor mechanical properties. In recent years, with the diversification of molded products, there has been an increasing demand for low cost and short delivery times for resin molds for high-mix, low-volume production. There is a need for something that improves the strength of its physical properties, and various attempts have been made for that purpose. However, most of those attempts
Alternatively, efforts are being made to improve strength by changing alloy components by adding Cu, Ti, Be, or the like.

ある。(Problems to be Solved by the Invention) Zinc-based alloys used for resin molds are generally casting alloys in which about 4% M and about 1 ton of Cu are added to Zn. However, since these alloys have weak mechanical properties, there is a problem that cracks occur at the corners when used in molds. For this reason, attempts have been made to improve mechanical strength by changing the alloy components, and although some results appear in small test specimens, there are currently various problems in applying this to large products such as molds. . An example of this can be explained with reference to Figure 9. For products containing A/-, the solidification rate is greatly affected, and in large products such as molds, the solidification rate varies depending on the location, so the solidification rate is uniform and stable. It is difficult to obtain an improvement in strength, and an increase in the amount of At added worsens the vortex flow, which causes cavities to easily occur and transferability to deteriorate, which poses problems in the production of cast products. In addition, the solidification rate is greatly affected by the total addition of Cu, and in addition, the ε phase 4 is produced in the Zn AL Cu ternary metal.
(Although an improvement in hardness can be expected, no significant improvement can be expected in terms of strength.Furthermore, when Ti or Bef is added, a ternary metal alloy of Zn-At-Cu forms the base, so At or Cu Similar to when K is added, the coagulation rate is significantly affected and mechanical strength is reduced.

ＰＭＡ写真を示す。After that, the steel material was heated to 150~26℃ for the purpose of drying and preheating.
After being heated at 5° C. for a predetermined time, the mold is placed at a predetermined position in a mold, and a zinc-based alloy having a molten metal temperature of 420 to 520° C. is poured into the mold to cast a steel material. At this time, diffusion between F'e and Zn is promoted, and this diffusion begins around 380 to 390°C, which is the melting temperature of zinc-based alloys, and becomes active as the temperature rises until it reaches around 500°C. It shows a very thick value and then becomes a gradual state. On the other hand, the preheated steel material is heated by the molten metal as shown in Figure 3, and its temperature is raised to around the pouring temperature of the zinc-based alloy, which sufficiently promotes diffusion at the interface between the steel material and the zinc-based alloy. The molten metal is held for a total of 10 to 20 minutes until it solidifies, and then allowed to gradually cool down. That is, the diffusion of the zinc-based alloy and the steel material takes place during the period T in FIG. Figure 1 shows a micrograph (400x) of the boundary between the composite zinc-based alloy steel and zinc-based alloy in which the steel is cast with the zinc-based alloy.

Heat for 15 minutes and hold the cast in place in the mold. When resin is injected into the space 4, an internal force is applied to the resin mold, so all steel members are placed in the mold to counteract that force, and molten zinc-based alloy is poured into the mold to form a round rod with a mouth shape.
