ド鋳型造型方法及び装置に係るものである。DETAILED DESCRIPTION OF THE INVENTION The invention of this application relates to a method and apparatus for forming a shell mold used for casting, and in particular, static electricity is charged to a powder binder and a base material to prevent static electricity from forming on the surface of the mold. This invention relates to a shell mold mold making method and apparatus in which shell sand is backed up and sintered after being adsorbed.

焼結する方法が行なわれていた。 Conventionally, the mold coating method used when making shell mold molds has been to apply a single mold coating agent to the surface of the mold only once, and then to back up shell sand and sinter it.

有していた。 Therefore, regarding the application of the above-mentioned mold coating agent, it is first necessary to uniformly apply the mold coating agent when applying it to the mold, and also, when backing up the shell sand afterwards, it is necessary to integrate it with the sintered shell sand. After that, releasability from the mold was required. In this way, because contradictory properties are required, such as uniform adhesion to the mold and releasability, it is difficult to adjust the composition of the mold coating agent and select materials, reducing manufacturing costs and improving quality. This method not only has the drawback of being difficult to maintain, but also requires skill in applying the coating agent to the mold, resulting in a reduction in work efficiency.

シリコーン系液状の離型剤２６を吹付けておく。 First, the mold 2 is set on the table 3 and preheated to a predetermined temperature, and a silicone liquid mold release agent 26 is sprayed onto the surface as shown in FIG. 4a.

melts on the surface of the mold 2 and binds the base materials 28 together, thereby improving the casting surface of shell casting.

ポキシ樹脂系のものが最適である。 Then, the binder 29 melts on the base film 28, penetrates into the base film 28, binds the base materials together, and binds the shell sand and the base material during backing up of the shell sand in the subsequent stage. It acts in such a way as to cause Therefore, the material selection conditions for binder 29 are relatively stricter than for binder 27, and binder 29 has high adhesiveness and fluidity (flows easily when melted), and has a relatively long melting time. A resin is required, for example an epoxy resin type is most suitable.

と一体化し密着する。 After each coating is formed by passing through the coating agent discharging device, the shell sand discharging device 25 passes through, and the shell sand 30 is backed up as shown in FIG. As the sintering of the shell sand 30 is carried out, each film of the binder and the base material becomes sintered by the action of the binder 29.
It is integrated with and adheres closely to.

割合程度でよい。勿論この割合以外であつても上
述の塗型剤としての働きをすることは出来る。 The ratio of the amount of spraying of the powder base material 28 and each of the binders 27 and 28 varies depending on the grain size of the powder base material 28 and other required casting surface roughness, but for example, if the grain size of the base material 28 is 300. If it is before or after meshing, the ratio of base material is 28
The ratio of binder 27 and binder 29 to 100 parts may be approximately 10 parts and 20 parts, respectively. Of course, even if the ratio is other than this, it can function as the above-mentioned mold coating agent.

される。 Particularly, when this shell mold mold making method is carried out using the apparatus 1 shown in FIG. Since the binder and the base material are easily mixed uniformly during sintering on the shell sand, the adhesion to the shell sand is improved. Therefore, the finish of the shell mold is improved compared to the case where a general electrostatic powder spray gun is used as the coating agent discharging device.

Of course, the coating process may be omitted. Also, the pipes 22, 23,
24 are brought sufficiently close to each other, and the base material 28 and the binder 2 are
