これまでの操作は、係合操作片７を使用して、前面側で全て行われている。 All the operations so far are performed on the front side using the engagement operation piece 7.
次に以上とは逆に、後側金型Ｘｂが、後面側の締板体２ｂによって、完全にクランプされるまでの操作につき説明する。 Next, contrary to the above, the operation until the rear mold Xb is completely clamped by the rear clamping plate 2b will be described.
まず、前側金型Ｘａをクランプする（或いはクランプしない）ニュートラルな位置に前面側の締板体２ａをセットし、後側金型Ｘｂの後面側の締板体２ｂによるクランプ処理を行うために、図６に示すように、上記第１の進退体３頭部３０の凹みに、上記係合操作片７の多角部突片を嵌合させ、該係合操作片７を操作させることで、前面側の締板体２ａ側に第１の進退体３を後退させれば、同図に示されるように、第１の進退体３の先端頭部３０が前面側の締板体２ａの凹みを押し、その結果、前面側の締板体２ａの平面が押され、前面側の締板体２ａのクランプ部反対側が支え板１０２に当接するまで移動し、前面側の締板体２ａは、前側金型Ｘａをクランプするニュートラルな位置にセットされることになる。その際、後面側の締板体２ｂは、後面側の上記弾性体６ｂの弾発力により、後面側の揺動支点２０ｂを中心に揺動せしめられて、後側金型Ｘｂの開放の準備が可能な状態（クランプ部の開放準備処理状態）になる。即ち、後面側の締板体２ｂは、最大に開いた状態になる。 First, in order to set the front side clamping plate 2a at a neutral position for clamping (or not clamping) the front die Xa, and to perform the clamping process by the rear clamping plate 2b on the rear die Xb, As shown in FIG. 6, the front surface of the first advancing / retracting body 3 is fitted into the recess of the head portion 30 of the engagement operation piece 7 and the engagement operation piece 7 is operated. If the first advancing / retracting body 3 is retracted to the side of the fastening plate body 2a, as shown in the figure, the tip head portion 30 of the first advancing / retreating body 3 causes the depression of the fastening plate body 2a on the front side. As a result, the flat surface of the front clamping plate 2a is pushed and moves until the opposite side of the clamping portion of the front clamping plate 2a contacts the support plate 102. The front clamping plate 2a It is set at a neutral position for clamping the mold Xa. At that time, the rear-side clamping plate 2b is swung around the rear-side rocking fulcrum 20b by the elastic force of the elastic body 6b on the rear-side, and preparation for opening the rear mold Xb is performed. Is possible (clamping part opening preparation processing state). That is, the fastening plate 2b on the rear surface side is in a fully opened state.
次に、上記係合操作片７を抜き、図７に示すように、該係合操作片７の多角部突片を上記クランプ量調整体４の穴４０に嵌合させ、該係合操作片７を回動させて、図８の位置（図１では係合操作片７の下辺が上記ストッパ７０で動きを制される位置）に来た時、後面側の締板体２ｂは、上記揺動支点２０ｂを中心に回動して、上記最大に開いた位置から次第にその開きを縮めた状態になる。この位置で係合操作片７の下辺を上記ストッパ７０で止めると、後側金型Ｘｂが、図１の左又は右側からの横入れができる状態になる。或いは、この状態の時に、図８に示すように、後側金型Ｘｂを、下方から入れることが可能な状態になる。 Next, the engagement operation piece 7 is pulled out, and, as shown in FIG. 7, the polygonal protruding piece of the engagement operation piece 7 is fitted into the hole 40 of the clamp amount adjusting body 4, and the engagement operation piece 7 is rotated to reach the position shown in FIG. 8 (in FIG. 1, the position where the lower side of the engagement operation piece 7 is restrained by the stopper 70), the rear clamping plate 2b It rotates about the moving fulcrum 20b, and the opening is gradually contracted from the maximum opening position. When the lower side of the engagement operation piece 7 is stopped by the stopper 70 at this position, the rear mold Xb can be inserted horizontally from the left or right side in FIG. Alternatively, in this state, as shown in FIG. 8, the rear mold Xb can be inserted from below.
横入れ、又は下入れによって、後側金型Ｘｂが後面側の締板体２ｂによりクランプできる状態になったならば、係合操作片７を回動させて、図９に示す位置（図１では係合操作片７が一番右側になる位置）にセットされる。後側金型Ｘｂは、後面側の締板体２ｂによって、完全にクランプされる。 When the rear mold Xb can be clamped by the rear clamping plate 2b by lateral insertion or lower insertion, the engagement operation piece 7 is rotated to the position shown in FIG. 9 (FIG. 1). Then, the engagement operation piece 7 is set to the rightmost position). The rear mold Xb is completely clamped by the rear clamping plate 2b.
これまでの操作についても、係合操作片７を使用して、前面側で全て行われている。また、上記クランプ量調整体４は、上記係合操作片７の操作方向につき、前面側及び後面側の各締板体２ａ、２ｂの各揺動支点２０ａ、２０ｂを中心にした揺動において、両側で反対向きになるように設定されると共に、本実施例では、その操作量については、前面側及び後面側の各締板体２ａ、２ｂの揺動量と同じになるようにして、金型Ｘａ、Ｘｂに対するクランプ及び開放ができるようにしてあるので、係合操作片７の操作量と前面側の締板体２ａと後面側の締板体２ｂの開放やクランプの処理量において、ハンドリング状違和感を生ずることがない。 All the operations so far are performed on the front side using the engagement operation piece 7. Further, the clamp amount adjusting body 4 swings around the swing fulcrum 20a, 20b of the front and rear fastening plates 2a, 2b with respect to the operation direction of the engagement operating piece 7. In this embodiment, the operation amount is set to be opposite in both sides, and the amount of operation thereof is set to be the same as the swing amount of each of the fastening plate bodies 2a and 2b on the front side and the rear side. Since the clamp and release with respect to Xa and Xb can be performed, the amount of operation of the engagement operation piece 7 and the amount of opening and clamping of the front-side clamping plate 2a and the rear-side clamping plate 2b and the processing amount of the clamping There is no sense of incongruity.
さらに、以上の説明は、前側金型Ｘａ及び後側金型Ｘｂのクランプ或いは取り外しに、関する操作につき説明したが、前面側の締板体２ａ、後面側の締板体２ｂのそれぞれの取外し、再組付けは、前面側の締板体２ａ或いは後面側の締板体２ｂの上記サドル２１ａ、２１ｂが固定支持体１の上記溝１１ａ、１１ｂにかみ合っているだけなので、これらの処理も簡単に行えることになる。 Furthermore, although the above description demonstrated the operation | movement regarding clamping or removal of the front side metal mold | die Xa and the rear side metal mold | die Xb, each removal of the clamping board body 2a of the front side, and the clamping board body 2b of the rear surface side, In reassembly, the saddles 21a and 21b of the front-side clamping plate 2a or the rear-side clamping plate 2b are engaged with the grooves 11a and 11b of the fixed support 1, so that these processes can be easily performed. It will be possible.
以上説明した本実施例の構成によれば、前面側の締板体２ａ及び後面側の締板体２ｂを基本的に同一の機構とした上で、且つ前面側の締板体２ａ、後面側の締板体２ｂのそれぞれの取外し、再組付けに際して、係合操作片７以外の工具を使用することなく簡単に行う事ができ、且つ前側金型Ｘａ及び後側金型Ｘｂの装着、取外しに際し、表付け、裏付けを基本的に同一の作業内容とすることが可能となった。 According to the configuration of the present embodiment described above, the front-side clamping plate 2a and the rear-side clamping plate 2b have basically the same mechanism, and the front-side clamping plate 2a and the rear side Each of the fastening plate bodies 2b can be removed and reassembled easily without using a tool other than the engagement operation piece 7, and the front mold Xa and the rear mold Xb can be mounted and removed. At the same time, it became possible to have the same work contents for the front and back support.
従って、クランプ装置を構成する前面側の締板体と後面側の締板体の機構が異なっていた従来構成で、取外、再組み付けには、工具を用い少なからぬ時間を要する問題や、取り外した部品の散逸による生産性の低下、及びクランプ装置を構成する前面側の締板体と後面側の締板体の機構が異なっていたことによる、金型の装着、取外し作業の煩雑性の問題も解消することになる。 Therefore, the mechanism of the front plate and the rear plate that make up the clamping device is different, and it takes a lot of time to remove and reassemble the tool and remove it. Productivity drop due to dissipated parts and the mechanism of the front and rear clamping plates that make up the clamping device are different, and there is a problem in the complexity of mounting and removing molds. Will also be resolved.
