Casting method casting
The present invention relates to a casting prototype casting method, and more particularly to a casting prototype casting method to enable a large number of casting prototype casting in one silicon type, while shortening the product manufacturing period and eliminating casting defects will be.
In general, in the conventional precision casting manufacturing method, only one product is cast in one ceramic mold.
In addition, conventionally, there are many problems such as casting defects after casting defects.
Therefore, in the end, there have been many problems such as lowering productivity and costing a lot in manufacturing.
The present invention is to solve the above-mentioned problems, to provide a casting prototype casting method to enable the casting of a large number of casting prototypes in one silicon type, while reducing the production period and eliminating casting defects. There is a purpose.
1 is a flow chart showing a conventional prototype manufacturing process
2 is a schematic view showing a technical apparatus of the present invention
3 is a flow chart showing the casting prototype casting process of the present invention.
* Description of the symbols for the main parts of the drawings *
1: vacuum furnace 2: silicon type
In order to achieve the above object, the present invention provides a casting prototype casting method using a vacuum furnace, performing a step of producing a wooden mold having a physical opposite shape, and performing a gypsum operation having the same shape as the real and Performing a process of fabricating a silicon mold using silicon after the step, separating a portion along the parting line of the silicon mold, removing the plaster, and forming a silicon mold in the vacuum furnace. This is a casting prototype casting method by sequentially performing the steps of floating the molten aluminum mold.
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
1 is a schematic view showing the technical apparatus of the present invention, the present invention is a casting prototype casting method using a vacuum furnace 1, the step of performing a process for producing a wooden die having a shape opposite to the shape and the same shape as the real Performing a gypsum operation having a step, and performing a process of manufacturing a silicon mold 2 using silicon after the step, and separating a portion along the parting line of the silicon mold 2; The step of removing the gypsum and the step of putting the silicon mold 2 in the vacuum furnace 1 and floating the molten aluminum mold are sequentially performed.
On the other hand, the operation of the present invention is as follows.
When casting the casting prototype using the vacuum furnace 1 in the present invention, the operator first performs a process of manufacturing a wooden die having a shape opposite to the actual.
Thereafter, after the plaster work having the same shape as the real thing, and after the step to perform the process of manufacturing the silicon mold (2) using the silicon.
In addition, after the operation of separating along the parting line of the silicon mold (2) to remove the gypsum, after this is finished the vacuum state (1) in the vacuum state using a vacuum pump (3) In the state of making the silicon mold (2) is put and the molten aluminum mold is floated.
The present invention enables the casting of a large number of casting prototypes in one silicon mold, and has the effect of shortening the product manufacturing period and eliminating casting defects.
That is, since 20 to 30 castings can be cast with one silicon mold, productivity can be improved.
