【発明の詳細な説明】
（産業上の利用分野）
本発明は上下の型に設けた刃部によつて板材等
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 Industrial Application) The present invention relates to a trim die for press-cutting a plate or the like into a predetermined shape using blades provided on upper and lower dies.
（従来の技術）
鉄板等を所定形状に切断する装置としてトリム
型が知られている。このトリム型は一般に下型
と、この下型に対し昇降する上型とからなり、上
型を下型に向けて降下させ、パツドによつて下型
上にワーク（被切断物）を押え付け、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 a lower die 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 pad. 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
すれば靭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 in this way, 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 toughness.
このため従来にあつては、型本体を鋳造によつ
て製造した後、刃部を内盛り或いはインサートに
よつ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つてトリム型を製
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57−25276号に開示される技術が
知られている。 Therefore, a technique disclosed in Japanese Patent Application Laid-Open No. 57-25276 is known.
特開昭57−25276号は第５図に示すように鋳型

からは高硬度鋼の溶湯１０４を注湯し、材料特性
（硬度、靭性）の異なる素材からなるトリム型を
一体鋳造するようにしたものである。 JP-A-57-25276 discloses that a trim-shaped cavity 101 is formed in a mold 100 as shown in FIG. 5, and a runner 10 is connected to the cavity 101.
2 and 103 are formed separately, and the molten metal 105 of ordinary cast iron is supplied from one runner 103 and the other runner 102.
From there, molten metal 104 of high hardness steel is poured, and trim molds made of materials with different material properties (hardness, toughness) are integrally cast.
（発明が解決しようとする問題点）
上述したように別々の湯道によつてキヤビテイ
内に特性の異なる素材の溶湯を注湯する所謂二層
鋳造にあつては、各々の素材に鋳造後に熱処理を
施さなければならない。つまり高硬度鋳鉄につい
ては普通鋳鉄よりも高温の熱処理が必要となる
が、各部毎に温度条件を異ならせて熱処理するの
は困難で、このため硬度不足、鋳巣の発生等の金
属組織の調整に不具合が生じる。(Problems to be Solved by the Invention) As mentioned above, in so-called two-layer casting, in which molten metal of materials with different properties is poured into the cavity through separate runners, each material is heat-treated after casting. must be carried out. 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 part under different temperature conditions, and this makes it difficult to adjust the metal structure to prevent insufficient hardness, the formation of blowholes, etc. A problem occurs.
（問題点を解決するための手段）
上記問題点を解決すべく本発明に係るトリム型
は刃部となるループ状の高硬度鋼材を普通鋳鉄に
て鋳ぐるむこ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.
（作用）
鋳型内に刃部をセツトした状態で注湯すると、
注湯の熱により刃部が周方向へ膨張するが、この
膨張分は刃部の分割部の隙間によつて吸収され、
刃部は径方向に変形することがなく、セツトした

に抑制することができる。(Operation) When pouring 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.
The blade part 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 above deformation and the step difference in the split opposing surfaces can be further suppressed.
（実施例）
以下に本発明の実施例を添付図面にて基づいて
説明する。(Example) Examples of the present invention will be described below with reference to the accompanying drawings.
第１図は本発明に係るトリム型の下型を示し、

断するワークの板厚以下とすることが望ましい。 FIG. 1 shows the lower mold of the trim mold according to the present invention,
An upper mold is arranged above the lower mold 1 so that it can be raised and lowered by a ram or the like. The lower mold 1 consists of a mold body 2 and a blade part 3 which is integrally cast with the mold body 2.The overall shape of the blade part 3 is loop-shaped, and the two halves 3
As shown in FIG. 2, which is a partially enlarged view of FIG. 1, a gap g is formed between the divided opposing parts of each half body 3a and 3a. It is desirable that this gap g be less than or equal to the thickness of the workpiece to be cut.

方向のみの動きを許容するようにしている。 Furthermore, as shown in FIG. 3, recesses 4, 4 in the length direction are formed in the divided opposing parts of each half 3a, 3a of the blade part 3, and the guide member 5 is inserted into the recesses 4, 4. , the movement of each divided opposing portion in the radial direction is restricted, and movement only in the length direction is permitted.
以上の如き構造の下型１の鋳造方法を第４図に
基づいて説明する。 A method for casting the lower mold 1 having the structure described above will be explained based on FIG. 4.
先ず下型本体２と同一形状の消失模型６を形成

含む砂等の耐火材８で固め、鋳型とする。 First, a vanishing model 6 having the same shape as the lower die main body 2 is formed. The material used for the disappearing model 6 is one that vaporizes and disappears due to the heat of the molten metal, such as foamed resin. Then, the blade part 3 made of high-hardness steel is attached to the vanishing model 6, and in this state, the vanishing model 6 and the blade part 3 are set in the frame 7, and the surrounding area is hardened with a fireproof material 8 such as sand containing a binder. , as a mold.
次いで、消失模型６の部分に普通鋳鉄の溶湯を
供給する。すると消失模型６の材料は溶湯の熱に
よつて溶融消失し、模型６と溶湯とが入れ替り、
刃部３は普通鋳鉄の溶湯にて鋳ぐるまれる。 Next, molten ordinary cast iron is supplied to the part of the disappearing model 6. Then, the material of the disappearing model 6 melts and disappears due to the heat of the molten metal, and the model 6 and the molten metal replace each other.
The blade portion 3 is cast with molten ordinary cast iron.

能なガイド部材５によつて連結されているため、
刃部３の膨張は殆ど長さ方向のみにおいて生じ、
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
As the temperature rises, the blade part 3 expands, but the blade part 3 is composed of divided halves 3a, 3a, and a gap g is provided between the divided halves 3a, 3a, and the blade part 3 is further divided. Since the opposing parts are connected by a guide member 5 that can move in the length direction of the blade part,
Expansion of the blade portion 3 occurs almost only in the length direction,
The blade does not shift in the radial direction.
尚、実施例にあつては、刃部３を２つの半体に
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 halves.
また、型本体となる溶湯が刃部３に接触する以

給し、刃部３を昇温せしめるようにしてもよい。 In addition, before the molten metal that becomes the mold body comes into contact with the blade part 3, the temperature of the blade part is raised, and the blade part 3 and the mold body 2 are heated.
In order to increase the welding strength with the vanishing model 6, a heating element or a heat insulating material may be brought into contact with the blade part 3 exposed from the vanishing model 6. Furthermore, a preheating body made of a vanishing material is brought into contact with the blade part 3, so that the blade part 3 exposed from the vanishing model 6 is Before supplying the molten metal to the preheating body part, another runner may be used to supply the molten metal to the preheating body part to raise the temperature of the blade part 3.
