に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The mold of the present invention has a bulging portion that bulges in a direction intersecting with the die-removing direction of the core die, and has a shape that cannot be die-removed as an integral core. The present invention relates to a mold in which the bulging portion is composed of a sand core and the core mold is integrally removed.
（従来の技術） 従来、中子金型の抜型方向と交差する方向に膨出する
膨出部があり、一体の中子としては抜型できない形状の
ものは、中子金型を割金型にしている。(Prior Art) Conventionally, if there is a bulging portion that bulges in a direction that intersects with the die removal direction of the core die and the shape that cannot be released as an integral core, the core die is used as a split die. ing.
ところが割金型にすると、つぎの鋳造の準備のための
型組みに手間がかかる。However, when the split mold is used, it takes time to assemble the mold for preparation for the next casting.
そこで、例えば、特開昭60−72660号公報に記載され

面にテーパー面を備えた中央型と、このテーパー面に対
応するテーパー面を備えた側型とに中子を分割し、この
中央型と側型に連結機構を設けて抜型後の型組みを容易
にしている。Therefore, for example, an apparatus as described in JP-A-60-72660 has been proposed. In this device, the core is divided into a central mold having tapered surfaces on both sides and a side mold having tapered surfaces corresponding to the tapered surfaces, and a connecting mechanism is provided for the central mold and the side molds, and after the mold is removed. Makes it easy to mold.

ほか、ときには組立てできなくなることがある。(Problems to be Solved by the Invention) The core is used as a mold in order to improve the precision of the mold. However, if various mechanical mechanisms are incorporated into the core mold, dust will be generated on the fitting part, sliding part, etc.
Entrapments such as casting balls may be caught, and the dimensional accuracy may not be maintained, and sometimes assembly may not be possible.
このようなことから、なるべく中子金型は一体である
ことが望まれる。From this, it is desirable that the core mold is integrated.

とを特徴とするものである。(Means for Solving Problems) The mold of the present invention has been invented to solve the above problems, and is a bulge that bulges in a direction intersecting with the die cutting direction of the core die. Part is composed of sand core, the skirting board of the sand core is fitted into the core mold, and a conduit for ventilating compressed gas is arranged in the fitted part, and when the core mold is removed from the sand, The skirting board of the core is separated from the main body of the sand core to be removed from the mold.

Is fitted into the core mold (1) and the baseboard (3) of the sand core (2) is separated from the sand core body (4) when the core mold (1) is removed. Therefore, when the core die (1) is die-cut, the skirting board (3) of the sand core (2) is detached from the sand-core body (4) and is die-cut.
そして、鋳造物側に取残された砂中子本体（４）は、
鋳造物の型落し工程で除去される。And the sand core body (4) left on the casting side is
It is removed in the mold removal process.
