To manufacture molds, such as press molds used in the drawing process, a copy model made of plaster or the like is used. Furthermore, this imitation model is created using the master model. When making a copy model for mold processing from a master model, the wrinkle holding surface other than the product part mold surface is conventionally formed by adding a finishing allowance around the product part mold surface of the master model using a wooden frame, clay, etc. Then, a concave plaster model is roughly formed by injecting a molding agent such as plaster into the mold surface where the product part and the wrinkle pressing surface are integrated, and the wrinkle pressing surface is numerically controlled (NC) processed again using data to finish the surface. I went there and made it.

However, since conventional methods use wooden frames and clay, it takes time (man-hours) for rough modeling and clay modeling. Also, the lead time is long,
Unable to respond quickly to various requests. Furthermore, there is a drawback that there is a lot of waste because NC processing is performed after rough modeling.

In other words, the method for manufacturing a copying model of the present invention involves numerically controlling the surface of a foamed polystyrene frame to form a wrinkle pressing surface, and then assembling the frame to a master model and molding it with the mold surface of the product part of the master model. The method is characterized in that after the wrinkle pressing surface of the frame body is connected together, a molding agent is injected onto the integrated mold surface and solidified.

のを用いる。マスターモデルを取り囲み、嵌合可
能なものとすれば、マスターモデルに簡単に取付
けることができてよい。 The expanded polystyrene frame should have an appropriate size and shape to match the size and shape of the master model. If it surrounds the master model and can be fitted, it can be easily attached to the master model.
この枠体は全体が一体となつていても、又は複

合は、粘土などを用いて塞ぐとよい。 Numerical control processing is performed on the frame using data stored in a computer in advance to form a wrinkle pressing surface. Next, this frame is assembled to the master model. At this time, the mold surface of the product part of the master model and the wrinkle pressing surface formed on the frame are integrally connected. If there is a gap between the master model and the frame, it is a good idea to fill it up with clay.

First, as shown in FIG. 1a, a wrinkle pressing surface 3 is formed on the surface of a foamed polystyrene frame 1 using a numerically controlled processing device 2. As shown in FIG. Next, as shown in b, the master model 4 is held at a predetermined position, for example, at a position inclined in the press direction, by jacks 5 and 6, and the frame 1 is accurately assembled thereto, and the product part mold surface 7 and The wrinkle pressing surface 3 is integrally connected. Gap 8
If necessary, seal with clay. When plaster is injected onto the integrally connected mold surfaces and solidified, a concave copying model 9 of a predetermined thickness (for example, 50 mm) as shown in c is obtained. The copying model 9 is held in a predetermined position by a metal frame 10 or a steel pipe support 11, and after being subjected to finishing processing, it is used, for example, in manufacturing a press mold.

is tilted in the pressing direction using jacks 5 and 6, and using a wooden frame 12 and clay 13, the wrinkle pressing surface 3 is roughly shaped with a finishing allowance A. After injecting plaster onto the mold surface and solidifying it to obtain a concave rough tracing model 9 of a predetermined thickness, as shown in e, the finishing allowance A is processed using the numerically controlled processing device 2, Next, further finishing processing is performed to obtain a copy model 9. In this way, conventionally, the wrinkle pressing surface 3 was formed using a wooden frame or clay with the finishing allowance A taken into consideration, which took time for modeling. I couldn't do it.

As mentioned above, the copying model manufacturing method of the present invention uses a foamed polystyrene frame whose surface has been previously numerically controlled to form a wrinkle-pressing surface, and is used by assembling it onto a master model. This simplifies setup and reduces man-hours, improving work efficiency. Furthermore, the preparation of the master model and the processing of the foamed polystyrene frame can be done in parallel, reducing lead time.
