でなく直角状のものにて実施する場合もある。 In addition, in the above embodiment, an extruded material having a circular cavity is used, but it is possible to use a variety of hollow shapes.For example, as shown in FIG. It can also be successfully implemented using extruded materials. In addition, in the core mold, a curved plate c made of aluminum alloy is used as a part of the welding structure, but depending on the shape of the molded product, a rectangular plate instead of a rounded shape may be used.

の優れた諸効果に期待できる。 According to the present invention as described above, since the profile extruded material made of aluminum alloy has at least a flat surface on the side facing the molded product surface and a cavity inside, it can be used as the main material of the mold. A variety of excellent effects can be expected from the mold that is assembled using the welded structure.

コスト的にも非常に低下を促し得る。 In other words, if the mold is constructed using aluminum profile extrusions, mold cracking is less likely to occur, and the welded structure eliminates steam leakage, making it possible to use the mold satisfactorily even if the mold thickness is considerably thinner. The conventional wall thickness of 8 to 12 mm can be reduced to 1.5 to 7 mm. In addition, the conventional process of wooden mold → aluminum casting → machining is not necessary with the mold of this invention, and since the manufacturing process of the mold is started from the beginning, the mold delivery time from receiving the mold order to manufacturing finish is shortened. It is shorter, which has great manufacturing advantages. Furthermore, the conventional box frame made of aluminum casting is no longer necessary, and only a reinforcing frame made of iron frame is required.
It can also greatly reduce costs.

トも大きいものである。 Moreover, unlike the conventional piping structure for steam, water, etc., the mold according to this invention can pass steam, water, etc. into the cavity of the irregularly shaped extruded material, and the steam chamber etc. can be made smaller than the conventional mold. As well as reducing the amount of steam and water used, the mold is suitable for saving energy and has great economic merits.
