Description
【発明の詳細な説明】
この発明は射出成形機において射出成形の能率化を図り
特殊ゲートを形成するに当つてその形成を容易ならしめ
たゲート部分の金型に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mold for a gate portion in an injection molding machine, which improves the efficiency of injection molding and facilitates the formation of a special gate.
ここに特殊ゲートというのは、ランナからゲートに至る
部分を湾曲トンネルとしたもので、金型は製品を取り出
すための移動部分と固定部分があり、製品と共にランナ
部分の樹脂も除去されるためランナは前記金型の両部分
の接着面に沿つて多く設けられる。The special gate here is a curved tunnel from the runner to the gate, and the mold has a movable part and a fixed part to take out the product, and since the resin in the runner part is removed along with the product, are provided in large numbers along the bonding surfaces of both parts of the mold.
第１図は本発明の金型の設置部を示し、１が金型の固定
部分、２が移動部分、３が接着面である。FIG. 1 shows the installation part of the mold of the present invention, where 1 is a fixed part of the mold, 2 is a movable part, and 3 is an adhesive surface.
４は製品、５はランナ、６はゲートであつて、ランナ５

明にいう特殊ゲートの状態であつて、この湾曲トンネル
７はゲート６を製品の裏面部に容易に臨ませ、かつ切断
を容易にするためのもので、製作上湾曲トンネル７の形
成は極めて困難な加工である。4 is a product, 5 is a runner, 6 is a gate, and runner 5
The state of the special gate according to the present invention is to form a curved tunnel 7 extending from the gate 6 to the gate 6. Therefore, forming the curved tunnel 7 is an extremely difficult process.
故に本発明にあつては、ゲート６とランナ５の一部を包
含する穴８を設け、該穴８を充填する埋合９を二つ割の
二部分９ａ、９ｂから構成し、その二部分９ａ、９ｂに
わたるねじ孔１０を設け、ねじ孔１０に螺合する締付ね
じ１１によつて埋合９の固定装置が構成してある。Therefore, in the present invention, a hole 8 that includes the gate 6 and a part of the runner 5 is provided, and the filler 9 that fills the hole 8 is composed of two halves 9a and 9b. A screw hole 10 extending over 9a and 9b is provided, and a fixing device for the recess 9 is constituted by a tightening screw 11 that is screwed into the screw hole 10.
そして埋合９の二分割により分割面へそれぞれ半分ずつ
を刻設することによつて湾曲トンネル７の形成を可能と
なし、造成している。本発明は以上の構成を具備し、特
殊ゲートの設置を可能ならしめたもので、従来のトンネ
ルゲートの加工が機械のベッドを傾けるか、材料を傾け
るかして加工しかつ直線的な加工しかできなかつたのに
比べ、部分的に入子にして加工するため、加工作業も容
易で湾曲した複雑形状のゲート或はランナの精密な型を
得るに成功したものである。The curved tunnel 7 can be formed by carving each half on the divided surface by dividing the filler 9 into two. The present invention has the above-mentioned configuration and enables the installation of special gates. Conventional tunnel gate processing requires tilting the bed of a machine or tilting the material and processing in a straight line. Compared to the conventional method, since the process is partially nested, the process is easier and we were able to successfully create a precise mold for a gate or runner with a complex curved shape.
なお、前述の実施例の説明においては、埋合を垂直面に
より つ割するものを示したが、水平面やその他の手段
により つ割しても差支えないものである。また、埋合
は機械切削加工により製作するほか、放電加工や冷間鍛
造加工等によつても製作することが出来るものである。In addition, in the explanation of the above-mentioned embodiment, the case where the filler is divided into two pieces by a vertical plane is shown, but there is no problem in dividing the filling part by a horizontal plane or other means. In addition to being manufactured by mechanical cutting, the filler can also be manufactured by electric discharge machining, cold forging, and the like.
