本考案はクランプ装置に関し、特にボルトで金
型取付盤の盤面に固定するタイプのものに関す
る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a clamping device, and particularly to a type of clamping device that is fixed to the plate surface of a mold mounting plate with bolts.
一般に、射出成形装置やダイカスト装置では、
金型を金型取付盤の盤面に固定するため、各種方
式のクランプ装置が用いられている。
In general, injection molding equipment and die casting equipment
Various types of clamping devices are used to secure the mold to the surface of the mold mounting board.
通常、上記クランプ装置では、クランプ装置本
体を盤面に予め形成されたボルト穴にボルトで締
結して固定保持するか、或いは盤面にT溝が形成
されている場合には、T溝内にT形固定部材を配
設してクランプ装置本体に挿通したボルトの先端
部をT形固定部材に螺合することによりクランプ
装置本体を盤面に固定している。 Usually, in the above-mentioned clamp device, the clamp device main body is fixedly held by fastening it with a bolt to a pre-formed bolt hole on the board surface, or if a T-groove is formed in the board surface, a T-shaped groove is inserted into the T-groove. The clamp device body is fixed to the panel surface by disposing a fixing member and screwing the tip of a bolt inserted into the clamp device body into the T-shaped fixing member.
従来のクランプ装置では、基本的にクランプア
ームなどのクランプ部材がクランプ装置本体に支
軸を介して枢着されあるいは所定のクランプ作動
用の移動ストロークの範囲でのみ移動可能に装着
され、クランプ部材はクランプ装置本体に対して
所定の位置関係となるように設けられ、クランプ
装置本体の盤面上の取付位置を変えることにより
金型のサイズの変更に対応するようになつてい
る。 In conventional clamp devices, basically, a clamp member such as a clamp arm is pivotally attached to the clamp device main body via a support shaft, or is mounted so as to be movable only within a movement stroke range for a predetermined clamp operation. It is provided in a predetermined positional relationship with respect to the clamp device main body, and is adapted to accommodate changes in the size of the mold by changing the mounting position on the panel surface of the clamp device main body.
クランプ装置を盤面にボルトで固定する場合に
は、金型を異なるサイズのものと交換する毎にク
ランプ装置を盤面から取外し、別の位置に取付け
直さなければならずその作業が大変煩雑であつ
た。しかも、盤面の所望の位置にボルト穴がない
場合には、ボルト穴を新たに形成する必要があ
る。
When fixing the clamping device to the panel surface with bolts, the clamping device had to be removed from the panel surface and reattached to a different position each time the mold was replaced with one of a different size, which was a very complicated process. . Moreover, if there is no bolt hole at a desired position on the board surface, it is necessary to newly form a bolt hole.
そこで、クランプ装置の位置を変更するのを避
ける為に、金型のサイズを一定にするという対策
が採られることも多い。 Therefore, in order to avoid changing the position of the clamping device, a measure is often taken to keep the size of the mold constant.
クランプ装置を盤面にT溝を介して固定する場
合には、T溝は通常縦横には形成されておらず一
方向にのみ形成されているので、T溝方向へはク
ランプ装置を自由に移動することが出来るが、T
溝と直交方向へはクランプ装置を自由に移動させ
ることが出来ないので金型の交換に際してクラン
プ装置を取付け直さなければならないことも少な
くない。しかも、金型取付盤にT溝が全く形成さ
れていないことも多いので、T溝を活用してクラ
ンプ装置を固定する方式は汎用性に欠ける。 When fixing the clamp device to the board surface via a T-slot, the T-slot is usually not formed vertically and horizontally but only in one direction, so the clamp device can be moved freely in the direction of the T-slot. It is possible, but T
Since the clamping device cannot be freely moved in the direction perpendicular to the groove, it is often necessary to reinstall the clamping device when replacing the mold. Moreover, since the mold mounting board often does not have any T-slots, the method of fixing the clamp device using the T-slots lacks versatility.
更に、従来のクランプ装置は、基本的に1台の
クランプ装置に1個のクランプ部材しか設けられ
ていないので、通常1個の金型を固定するのに4
台のクランプ装置を用いる。この場合、金型交換
毎に4台のクランプ装置の位置を変えなければな
らないのでその作業がかなり面倒であるだけでな
く、クランプ装置へ油圧を供給する油圧ホースな
ども多くその取扱いも煩雑になる。 Furthermore, in conventional clamping devices, basically only one clamping member is provided in one clamping device, so it usually takes four to secure one mold.
Use a stand clamp device. In this case, the positions of the four clamping devices must be changed every time the mold is replaced, which is not only quite cumbersome, but also requires a large number of hydraulic hoses that supply hydraulic pressure to the clamping devices, making their handling complicated. .
本考案の目的は、クランプ装置本体の位置を変
えることなくクランプ作用点部の位置を自由に変
更できるようなクランプ装置を提供することであ
る。 An object of the present invention is to provide a clamp device in which the position of the clamping point can be freely changed without changing the position of the clamp device main body.

In the clamping device according to the first aspect, a plurality of hydraulic cylinders are incorporated into the elongated block-shaped main body member perpendicularly to the board surface, and the main body member is attached to the board surface via the piston rod of the hydraulic cylinder to a predetermined position outside the board surface. Since it is held in position, when the hydraulic cylinder is driven, the clamp member is pressed toward the board surface by the main body member, the fulcrum part of the end of the clamp member on the side opposite to the mold comes into contact with the board surface, and the other end The mold is pressed at the point of action, and the mold is fixed to the mold mounting board.
