Description

産業上の利用分野Industrial application fields

本発明は一般的な金型の締付け装置に関する。  The present invention relates to a general mold clamping apparatus.

射出成形機の金型は機械装置のプラッテンにクランプによりボルト締結されて使用されているが、プラッテンに取付けられる金型の寸法には大小があり、その都度クランプの大きさを対応させねばならず、図６で示すようにプラッテン限度に近い大型金型の場合にはストラップ支点が外れてしまう場合もあり、少なくとも３種類のクランプが必要で多数の射出成形機を備える場合の費用は高額とならざるを得ない。The mold of an injection molding machine is used by being bolted to a platen of a mechanical device with a clamp, but the size of the mold attached to the platen is large and small, and the size of the clamp must be adjusted each time. As shown in FIG. 6, in the case of a large mold close to the platen limit, the strap fulcrum may come off, and at least three types of clamps are required, and the cost when a large number of injection molding machines are provided is expensive. I must.

金型にはフランジの無い構造があると共に締付け位置が不定の場合もある。この場合には従来のクランプでは締付けが不可能なので先端を合わせ加工して対応しているのが現状である。The mold has a structure without a flange and the tightening position may be indefinite. In this case, since it is impossible to tighten with a conventional clamp, the present situation is that the tip is aligned and processed.

発明が解決しようとする課題Problems to be solved by the invention

金型を締結するためのフランジの大きさと厚みの変化に対応できる安価で操作性の良い金型用クランプを得る。An inexpensive and easy-to-operate mold clamp capable of responding to changes in the size and thickness of a flange for fastening a mold is obtained.

課題を解決するための手段Means for solving the problem

上記目的を達成するために本発明の「金型用クランプ」では、従来のストラップとリンクで結合され固定された駒を移動式の駒とする。その駒にはストラップに固定する為の取付ボルト用のネジ孔があり、取付ボルトが螺合される。In order to achieve the above object, in the “mold clamp” of the present invention, a conventional piece coupled with a strap and a link is fixed as a movable piece. The piece has a screw hole for a mounting bolt for fixing to the strap, and the mounting bolt is screwed together.

作用Action

大小の金型寸法に対しプラッテンの中央部から端部に至るまで一種類の金型クランプで対応出来る。One type of mold clamp can be used for large and small mold dimensions from the center to the end of the platen.

図１、２、３及び４において、１はストラップ、２は段付ピン、３は締付ボルト、４は受座、５は駒、６は取付ボルトである。プラッテン１は角断面並列のバー構造であり、締付ボルト３はその内側に配置されている。並列配置されたプラッテン１は段付ピン２により一体化されている。受座４はコの字型の形状でプラッテン１に摺動自在に装着され、締付ボルト３が貫通している。５は駒であり駒５は短辺ｃと長辺ｄの矩形断面を持った角材で作られ、ネジ孔５ａ及び５ｂが直交して設けられている。そして取付ボルト６が何れかのネジ孔に螺合しストラップ１に固定する。1, 2, 3 and 4, 1 is a strap, 2 is a stepped pin, 3 is a fastening bolt, 4 is a seat, 5 is a piece, and 6 is a mounting bolt. The platen 1 has a bar structure with parallel square sections, and the tightening bolt 3 is disposed inside thereof. The platens 1 arranged in parallel are integrated by a stepped pin 2. The seat 4 has a U-shape and is slidably mounted on the platen 1, and the tightening bolt 3 passes therethrough. Reference numeral 5 denotes a piece. The piece 5 is made of a square member having a rectangular cross section having a short side c and a long side d, and screw holes 5a and 5b are provided orthogonally. Then, the mounting bolt 6 is screwed into any of the screw holes and fixed to the strap 1.

締付ボルト３と取付ボルト６との中心距離は図１ではａ、図２せはｂであり金型の大きさにより締付ボルト３のプラッテンへの締付け位置が変化する。同様にストラップ１とプラッテンとの距離、即ち締付け厚さＨは金型の大きさにより変化する。駒５の締付け時の寸法もこれに対応し、図１ではｃ、図２ではｄである。The center distance between the tightening bolt 3 and the mounting bolt 6 is a in FIG. 1 and b in FIG. 2, and the tightening position of the tightening bolt 3 on the platen varies depending on the size of the mold. Similarly, the distance between the strap 1 and the platen, that is, the tightening thickness H varies depending on the size of the mold. The size of the piece 5 when tightened corresponds to this, and is c in FIG. 1 and d in FIG.

図５において、７はライナーで薄板で作られボルト孔７ａがある。金型の締付け厚さＨがｃとｄの中間値の場合には適宜厚さのライナーを適宜枚数ストラップ１と駒５の間に挿入し取付ボルト６で締結し対応する事ができる。In FIG. 5, 7 is a liner made of a thin plate and has a bolt hole 7a. When the clamping thickness H of the mold is an intermediate value between c and d, an appropriate thickness liner can be appropriately inserted between the strap 1 and the piece 5 and fastened with the mounting bolt 6 to cope with it.

発明の効果The invention's effect

本発明は以上のように構成されているので、下記のような効果が得られる。Since the present invention is configured as described above, the following effects can be obtained.

金型寸法の変化に対応するため従来は大中小の３種類の金型クランプが必要だったが、駒５の位置が自在に変動できるので１種類で対応する事が可能となり設備費が低減できる。Conventionally, three types of large, medium, and small mold clamps were required to cope with changes in the mold dimensions, but the position of the piece 5 can be freely changed, so it can be handled with one type and the equipment cost can be reduced. .

金型のフランジ厚さＨが変化し駒５の断面寸法ｃ及びｄに合致しなくてもライナーの挿入により、殆ど無段階に対応できる。Even if the flange thickness H of the mold changes and does not match the cross-sectional dimensions c and d of the piece 5, it can be handled almost steplessly by inserting the liner.
