るものの、加工費が嵩みコスト画となる欠点があった。Conventionally, as molds for precision vanishing models that use pouring type models such as naphthalene thread model materials and urea-based model materials, stone molds or full minilam molds made by cutting the mold surface have been used. However, in the case of the right-hand/female type, the mold is bulky, has poor thermal conductivity, and has the disadvantage of being easily damaged.On the other hand, the above-mentioned disadvantages are relatively improved in the case of the aluminum type. However, it had the disadvantage of increasing processing costs.

るものである。The purpose of the present invention is to provide a new copper mold which can provide a lightweight and highly accurate female mold for fugitive model molding, and which has good thermal conductivity and can speed up the model molding cycle IV. As a new and useful method for manufacturing all molding molds, the present invention is based on a copper material for a fully consumable electrode of an electroforming mother mold formed into a predetermined shape, and a V.
The main feature is that the mold is immersed in a C plating bath and plated, and copper is deposited on the surface of the mother mold to form a shell-like copper mold.

The arrow plane corresponds to the position of the A-A arrow plane in FIG. 1). The matrix (2) has a convex portion (

After 2b) is subjected to a conductive treatment, it is immersed together with a copper material for a consumable electrode in a plating solution such as copper sulfate or copper borate solution, and electricity is passed between it and the electrode steel material. Then, due to the action of the battery, the copper melted from the consumable electrode is electrolytically transferred to the surface of the matrix in a layered manner, and after a certain period of time, the surface of the matrix is coated with copper layers in the order of several fins or several fins.

7: Molds can be made easily and accurately, but this illegally manufactured copper mold has the following remarkable advantages. The mold made according to the present invention is made of a thin shell-like material, so it can be seen visually.
Moreover, since the surface is faithfully transferred to the mother mold surface, a product with high surface precision can be obtained.In addition, since the entire mold is made of pure copper with high thermal conductivity, its cooling ability is high. I can't mention it. In other words, because of its large cooling capacity, the solidification and cooling of the model material liquid injected into the mold proceed in a short period of time, which not only shortens the model molding work time, but also allows the model material to cool on the surface of the model. This results in an extremely dense structure. By the way, this copper 4
Comparing the mold to a female plaster mold, the weight is approximately 1, the molding time is 1~↓, and 5 5 8
