（＆梁上の利用分野）
未発明は上下の型に設けた刃部によって板材等を所定形
状にプレス切断するトリム型に関する。DETAILED DESCRIPTION OF THE INVENTION (& Field of Application on Beams) The present invention relates to a trim die for press-cutting a board or the like into a predetermined shape using blades provided on the upper and lower dies.
（従来の技術）

付け、この状態で上下の型に設けた刃部にてワークを所
定形状に押し切りするようにしたものである。(Prior Art) A trim type is known as a device for cutting iron plates or the like into a predetermined shape. This trim die generally consists of an F-type and an upper die that moves up and down relative to the lower die.The upper die is lowered toward the lower die, and the workpiece (object to be cut) is held down on the lower die by a band. In this state, the workpiece is pressed into a predetermined shape using blades provided on the upper and lower molds.
このようにトリム型の刃部は鉄板等を切断するものであ
るので、高炭素鋼等の高硬度の鋼材にて構成する必要が
ある。一方型本体は加工等を考慮すれば惰性に優れた普
通鋳鉄にて構成するのが好ましい。Since the trim-type blade part cuts iron plates and the like as described above, it needs to be made of high-hardness steel such as high-carbon steel. In consideration of machining, etc., it is preferable that the main body of the mold is made of ordinary cast iron, which has excellent inertia.
このため従来にあっては、型本体を鋳造によって製造し
た後、刃部を内盛り或いはインサートによって型本体に
形成するようにしている。For this reason, conventionally, after the mold body is manufactured by casting, the blade portion is formed in the mold body by filling or inserting.
しかしながら以上の手段によってトリム型を製造すると
、型本体の鋳造後に別工程として刃部を形成しなければ
ならず、生産効率及びコスト面において不利が生じる。However, when the trim mold is manufactured by the above method, the blade portion must be formed as a separate process after the mold body is cast, which is disadvantageous in terms of production efficiency and cost.
そこで特開昭５７−２５２７８号に開示される技術が知
られている。Therefore, a technique disclosed in Japanese Patent Laid-Open No. 57-25278 is known.

From 02) onwards, molten metal (100) of high hardness steel was poured and trim molds made of materials with different material properties (hardness, toughness) were integrally cast.

等の金属組織の調整に不具合が生じる。(Problems to be Solved by the Invention) 1-As mentioned above, in so-called two-layer casting in which molten metal of materials with different properties is poured into a cavity through separate runners, each material is heat-treated after casting. In other words, high-hardness cast iron requires heat treatment at a higher temperature than normal cast iron, but it is difficult to heat treat each type under different temperature conditions, resulting in insufficient hardness and formation of cavities. Problems occur in the adjustment of metal structure such as generation.

上記問題点を解決すべく本発明に係るトリム型は刃部と

でトリム型を一体鋳造し、更に刃部をループの長さ方向
において少なくとも２つ以上に分割した。(Means for Solving the Problems) In order to solve the above problems, the trim mold according to the present invention is made by integrally casting the trim mold by casting ordinary cast iron around a loop-shaped high-hardness steel material that will become the blade part. Furthermore, the blade portion was divided into at least two parts in the length direction of the loop.

差は更に抑制することができる。(Function) When pouring metal with the blade set in the mold, the blade expands in the circumferential direction due to the heat of pouring, but this expansion is absorbed by the gap between the divided parts of the blade, and the blade expands. It does not deform in the radial direction and can be cast in the set state. In particular, if the split opposing parts are connected by a guide member that allows movement in the length direction of the loop, the L arrangement shape and the level difference between the split opposing surfaces can be further suppressed.

径方向には刃部がずれることがない。Here, when the molten metal comes into contact with the blade part (3), the blade part (3)
temperature rises, the blade part (3) expands by 1, but the blade part (3) expands by 1.
) is composed of divided half-holes (3a) and (3a), and there is a gap (g
) is provided, and the split opposing parts are connected by a guide member (5) that is movable in the length direction of the blade, so expansion of the blade (3) occurs almost only in the length direction.
The blade does not shift in the radial direction.
尚、実施例にあっては、刃部（３）を２つの半休に分割
したがこれ以上に分割してもよい。In the embodiment, the blade portion (3) is divided into two halves, but it may be divided into more than two halves.
