Abstract
Description
本発明は樹脂の成型方法、及び成型品に関する。 The present invention relates to a resin molding method and a molded product.
樹脂成型品にネジ穴を設ける場合、所望の穴径より小さな穴を成型時に開けておき、ネジタッピング等でねじ山を形成するなど後加工が必要であった。そこで、本発明は射出成型時にネジ穴も成型してしまい、後加工などの手間を省力化することを課題とする。 When a screw hole is provided in a resin molded product, a post-processing such as forming a screw thread by screw tapping or the like by opening a hole smaller than a desired hole diameter at the time of molding is necessary. In view of the above, the present invention has an object of saving labor such as post-processing by forming a screw hole at the time of injection molding.
一部または前長に渡り螺旋形状を施した突出ピンを金型に摺動且つ回転自在に係止し、金型から成型品を取り出す際には突出ピンを回転させながら引き抜く方法で課題を解決する。 The projecting pin, which has a spiral shape over part or front length, is slidably and rotatably locked to the mold, and when taking out a molded product from the mold, the problem is solved by pulling out while rotating the projecting pin. To do.
成型品が金型から取り出された段階で既にネジ穴が形成されているので後加工などが不要になる。 Since the screw holes are already formed when the molded product is taken out from the mold, post-processing and the like are unnecessary.
金型の固定側又は移動側のどちらかの型に、突出ピンが摺動且つ回転自在に係止しされるように摺動穴を設け、突出ピンを組み付ける。 A sliding hole is provided on either the fixed side or the moving side of the mold so that the protruding pin is slidably and rotatably locked, and the protruding pin is assembled.
突出ピンを摺動穴に沿って出入れさせる第１の機構と、突出ピンを回転させる第２の機構とからなる。 It consists of a first mechanism for moving the protruding pin in and out along the sliding hole, and a second mechanism for rotating the protruding pin.
図示しないが、第１の機構、第２の機構、樹脂の射出、金型のスライド、押出ピンなどの制御を制御手段が行う。 Although not shown, the control means controls the first mechanism, the second mechanism, the resin injection, the mold slide, the extrusion pin, and the like.
次に図を用いて成型時の動作説明する。 Next, the operation during molding will be described with reference to the drawings.
図１（a）は突出ピンが引っ込んでいる状態である。金型２、３のどちらかがスライドし、金型どうしが閉じ合わされる。 FIG. 1A shows a state in which the protruding pin is retracted. One of the molds 2 and 3 slides and the molds are closed.
次に突出ピンを突出させる。 そして注入口４から樹脂を流し込む。 Next, the protruding pin is protruded. Then, resin is poured from the inlet 4.
所定時間がたち、樹脂が有る程度硬化したときに、突出ピンを抜き出し方向に回転させ抜き出す。 When the predetermined time has passed and the resin has hardened to some extent, the protruding pin is rotated in the extraction direction and extracted.
次に金型２、３のどちらかがスライドして、成型品を取り出す。以上の工程により射出成型と同時にネジ穴を成型することができる。 Next, one of the molds 2 and 3 slides to take out the molded product. The screw hole can be formed simultaneously with the injection molding by the above process.
なお、この発明で形成されるネジ穴の利用方法に関して一例を以下に記す。ネジ穴が見えないようにゴムや樹脂で出来た蓋を穴に被せる場合があるが、何かの拍子に、この蓋が外れてしまうことがある。しかしながら本発明によるネジ穴に蓋を被せた場合、ネジ山が蓋に食込み、抜けにくくなる。 In addition, an example is described below about the utilization method of the screw hole formed by this invention. A lid made of rubber or resin may be put on the hole so that the screw hole cannot be seen, but this lid may come off at some point. However, when the screw hole according to the present invention is covered with the lid, the screw thread bites into the lid and is difficult to come off.
