Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an apparatus for manufacturing a casting.

[0002]

[Prior art]

 In a conventional casting manufacturing apparatus, molten metal is poured into a mold, the molten metal is cooled and solidified, and then the mold is destroyed and the casting is taken out, so that the casting work is extremely troublesome. There was a drawback that the manufacturing cost of castings was high.

[0003]

[Problems to be solved by the device]

 The present invention provides a casting manufacturing apparatus that can omit the trouble of flowing molten metal into a mold and can repeatedly use the mold.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the casting production apparatus of the present invention, as shown in the figure, allows the same amount of the metal solid matter as the casting to be cast through the opening to be heated and melted. A graphite mold formed, which is a heat-resistant mold combination capable of maintaining a combination of a mold formed so as to be divided into two or more than two parts and the divided one of the molds. It consists of maintenance means.

In the present invention, the graphite is preferably a high density and isotropic material having high heat resistance and thermal shock resistance. Further, the graphite mold is required to be able to be heated in a heating furnace such as an electric furnace, or to be heated by itself as a heating element electrode. The heat-resistant mold coalescence maintaining means maintains the coalescence of two or two or more divided molds, and therefore, the heat-resistant outer-fitting body such as graphite for internally fitting the coalesced molds or the coalesced molds. It includes a clasping tool such as platinum that can be tied down.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention is shown in FIGS. The casting production apparatus of this example comprises split molds 1 and 2, a heat-resistant mold combined maintaining means 4 for holding a combination of the split molds 1 and 2, and a high temperature electric furnace (not shown). The split mold 1 is made of graphite and forms a split female die 11 and two ridges 12. The split mold 2 is made of graphite and is fitted into the split female die 21 and two ridges 12. The groove 22 is formed and the divided molds 1 and 2 are combined to form the mold 3. The heat-resistant mold combination maintaining means 4 is made of a heat-resistant material such as graphite and has a hole 41 so that the mold 3 can be fitted therein. Therefore, after the mold 3 in which the split molds 1 and 2 are combined is fitted into the heat-resistant mold combination maintaining means 4, as shown in FIG. 5, the molds 11 and 21 for dividing the solid metal 5 are combined and pooled. When placed in a mold 31 and heated in an electric furnace to melt the solid metal material 5, a casting 6 is completed as shown in FIG. 6, and the mold 3 is taken out from the heat-resistant mold coalescence maintaining step 4. The casting 6 can be easily taken out by dividing it into the split molds 1 and 2, and in some cases, the casting 6 can be easily taken out from the opening 30 by turning the mold 3 upside down.

[0007]

[Effect of device]

 According to the casting production apparatus of the present invention, the solid metal material put into the mold is heated and melted to become a casting, and the operation of taking out the casting as it is can be repeatedly performed. There is no need to pour molten metal into the mold that can be used, it is only necessary to pour solid metal into the mold, so cumbersome pouring operations and equipment are not required. It can be greatly reduced.
