A mold repair jig characterized in that it consists of a rod (3), and a central steel bar (2) of the mold repair jig (c) is inserted into the hole of the mold to be repaired. After installing the vertical holder ■ that holds the mold repair jig perpendicular to the mold surface, drive in the top of the bar (4) of the mold repair jig, and then This is a mold repair method in which the area around the repair hole is polished after removing the vertical holder (■) from the mold repair jig.The hole position to be repaired can be accurately determined, and the position of the hole to be drilled can be adjusted from the hole. As an equal interval, it is possible to make the holes uniform perpendicular to the mold surface, and it is possible to finish holes with high precision.

う−いわゆる1カジリ”−の現象が発生する。For punching holes in plate materials such as metal plates, resin plates, fiber-reinforced resin plates, etc., holes in molds such as punching holders (punching strippers or shedders) and dies are used to punch out holes on the plate material side of the holes during the punching process. A so-called "one-gauge" phenomenon occurs in which the side that touches the surface expands.
このいわゆる“カジリ1は、所望孔位置が通常不均質に
分布することによる打抜き時及び打抜かれた製品よりの
打抜きピンの抜き取り一特に後者の場合に抜き取り操作
の力の不均衡に伴う金型間の平行のくずれ、打抜き屑が
孔内に付着すること、更には、金型間の孔位置のずれな
どにより発生するものと考えられる。This so-called "galling" occurs during punching due to the usually non-uniform distribution of the desired hole positions and when the punching pin is pulled out of the punched product, especially in the latter case due to an imbalance in the force of the punching operation between the dies. This is thought to be caused by the collapse of the parallelism of the holes, the adhesion of punching debris into the holes, and the misalignment of hole positions between the molds.
この°カジリ”が発生すると、加工製品の孔形状の不良
の発生や、孔への打抜き屑の目づまり等が発生し、加工
状態が悪化する。When this galling occurs, the shape of the hole in the processed product may become defective, the hole may become clogged with punching chips, and the processing condition deteriorates.
従って、“カジリ1が生じるとその都度、金型を補修す
る必要がある。Therefore, whenever galling occurs, it is necessary to repair the mold.
このような°カジリ”の補修方法としては、丸タガネな
どの先端を尖らせた治具で孔周辺を等間隔、垂直に目視
などで打込み、研摩仕上げする方法によっていた。The method for repairing such galling was to use a jig with a sharp tip, such as a round chisel, to visually drive holes vertically at equal intervals around the hole, and then finish by polishing.
ところが、上記のような方法では、打込み位置や力の不

あった。However, with the above-mentioned method, it is difficult to improve the finishing accuracy of the hole because of unevenness in the driving position and force.
本発明は、以上のような欠点のない補修方法について検
討した結果完成したものである。 、r以下
、本発明を添付図面に基づいて説明する。The present invention was completed as a result of research on a repair method that does not have the above-mentioned drawbacks. , r Below, the present invention will be explained based on the accompanying drawings.

材棒状材2を挿入して、これを、通常丸鉄材などの棒材
3にねじ5により着脱自在に装着した金型補修治具Aを
示すものである。In Fig. 1, a central steel bar 2 of a size suitable for insertion into a mold repair hole is inserted into the center of a bladed metal fitting 1 made of steel or the like having a circular blade 4. This figure shows a mold repair jig A that is detachably attached to a bar material 3 such as the above with screws 5.
ここで刃付金、具1の円形刃4は、補修孔の直径より、
通常0.2〜211II直径の大きいものであり、又、
刃端の角度は、通常、外刃 40〜60°、内刃 30
〜70° の範囲が好ましい。Here, the circular blade 4 of the blade and tool 1 is determined from the diameter of the repair hole.
It is usually large in diameter from 0.2 to 211 II, and
The angle of the blade edge is usually 40 to 60° for the outer blade and 30° for the inner blade.
A range of ~70° is preferred.
又、中心鋼材棒状材2は補修孔に出し入れ自在なもので
あればより大きいものが好ましい。Further, the central steel bar 2 is preferably larger if it can be freely inserted into and taken out of the repair hole.

の高い補修ができるものである。FIG. 2 shows a state in which the mold repair jig A of FIG. 1 is inserted into the repaired hole 6 of the mold C and is held with a normal three-sided ruler-like vertical holder Bi trowel. In this state, the top of the mold repair jig A is driven in with a hammer to raise the mold material around the hole to be repaired. In the case of the first method, since the distance between the hole position and the driving position and the driving force can be made uniform, highly accurate repair with substantially no deviation in the hole position after finishing can be performed.
