れていた。ところが、この種材料はM量が大きいため、
段取り等の作業の際取扱いにぎわめて不便であった。A mold holder called a so-called swan-neck boulder is used to hold punch and die molds used for punching metal plates and the like on the support member. This mold boulder has conventionally been made of a T4 abrasive metal material such as FCD/15 (class 2 spheroidal graphite cast iron product). However, since this kind of material has a large amount of M,
It was extremely inconvenient to handle during work such as setup.
そこでこの問題点を解消するため、A−2C等のアルミ

It is. That is, in the method of the present invention, a core made of a wear-resistant metal material and having an engaging portion on its outer circumferential surface is placed in a mold for casting a small metal mold at a position corresponding to the punch and die mounting portion. The gist is to place an aluminum alloy into the mold and cast the aluminum alloy into the mold. Here,
When punches and tie cores are formed independently and cast, a lathe or the like is used to align the axes of the punch and die in the finished cast product. On the other hand, when forming the punch core and die core integrally, alignment is not necessary if the formed casting is divided by cutting between the banding part and the die mounting part. .
以下、図面を参照し実施例の詳細を説明する。Hereinafter, details of the embodiments will be described with reference to the drawings.

ダの製造方法を提供し得たものである。As is clear from the above explanation, in the mold holder casting method of the present invention, a core formed of a wear-resistant metal material and having engaging uneven portions on the outer circumferential surface is used as a punch and die mounting portion. Since the mold holder is manufactured by casting aluminum alloy into the mold placed in the specified position, the mold holder is significantly reduced in size compared to conventional mold holders, and it is extremely easy to handle for work such as setup during use. It becomes easier. Furthermore, since the sliding parts and the parts to which compressive force is applied are made of FCD45W, a material with wear resistance and high compressive strength, there is no fear of wear or damage. Furthermore, since the core is fitted into the aluminum alloy with an engaging portion provided on its outer circumferential surface, it is firmly fixed to the cast body and does not separate during use. Thus, the present invention solves the conventional problems and provides a method for manufacturing a mold holder that is lightweight, easy to handle, and has excellent wear resistance and compressive strength.
