Description

本発明は、固定盤に対して可動盤が水平方向に型開閉され、型部材が取付けられる回転テーブルが固定盤または可動盤の一方の盤に回転可能に設けられ、型部材の作動または型部材のクランプに流体が用いられるロータリ式射出成形機に関するものである。 According to the present invention, the movable platen is opened and closed horizontally with respect to the fixed platen, and a rotary table to which the die member is attached is rotatably provided on one of the fixed platen and the movable platen. The present invention relates to a rotary injection molding machine in which a fluid is used for clamping.

固定盤に対して可動盤が水平方向に型開閉され、型部材が取付けられる回転テーブルが固定盤または可動盤の一方の盤にて回転可能に設けられ、型部材の作動または型部材のクランプに流体が用いられるロータリ式射出成形機としては、特許文献１に記載されたものが知られている。特許文献１では可動金型に油圧により作動される型部材の中子が設けられている。そして前記中子を作動させるための各可動金型に向けて可撓性を有する長い油圧配管がターンテーブルの外周に沿うように設けられている。しかしながら特許文献１のものはどのようにして中子を作動させるかの記載がなく、図１ないし図３においては移動ブロックから金型までの経路にはバルブは配設されていない。従ってこの特許文献１のようにバルブ等を備えた油圧装置から可撓性を有する長い油圧配管を介して可動金型の中子の作動を行うものは、バルブからの距離が長くなるために中子の応答性に劣るという問題がある。またそれとともに供給される作動油の圧力損失を招きやすい。 The movable platen is opened and closed horizontally with respect to the fixed platen, and a rotary table to which the mold member is attached is provided so as to be rotatable on either the fixed platen or the movable platen, and for the operation of the mold member or clamping of the mold member. As a rotary injection molding machine in which a fluid is used, the one described in Patent Document 1 is known. In Patent Document 1, a movable mold is provided with a core of a mold member that is operated by hydraulic pressure. A flexible long hydraulic pipe is provided along the outer periphery of the turntable toward each movable mold for operating the core. However, there is no description of how the core is operated in Patent Document 1, and no valve is provided in the path from the moving block to the mold in FIGS. Therefore, in the case of operating the movable mold core from a hydraulic device having a valve or the like via a long flexible hydraulic pipe as in Patent Document 1, the distance from the valve becomes longer. There is a problem that the responsiveness of the child is inferior. Moreover, it is easy to cause the pressure loss of the hydraulic fluid supplied with it.

また水平方向に型開閉されるロータリ式射出成形機ではないが、特許文献２には縦方向に型開閉されるロータリ式射出成形機において、回転盤に金型を取付ける金型クランプ装置に油圧を用いたものが記載されている。特許文献２においてはバルブ装置１２が回転盤に設けられるためバルブ装置とクランプ装置の距離が近く、特許文献１のような応答性に劣るという問題は発生しない。また供給される作動油の圧力損失を抑制できるという点でも優れているものと思われる。更に特許文献２のように回転盤の中心軸の側から回転盤の金型クランプ装置に向けて作動油を供給する回転式射出成形機の場合は、バルブ装置を前記中心軸の側に設け、そこから金型クランプ装置へ配管を接続することは、配管の全長を短くする点において一見合理的でもある。 Further, although it is not a rotary type injection molding machine that opens and closes in the horizontal direction, Patent Document 2 discloses that in a rotary type injection molding machine that opens and closes in the vertical direction, hydraulic pressure is applied to a mold clamping device that attaches a mold to a turntable. The ones used are listed. In Patent Document 2, since the valve device 12 is provided on the rotating disk, the distance between the valve device and the clamp device is short, and the problem of poor response as in Patent Document 1 does not occur. It is also considered excellent in that the pressure loss of the supplied hydraulic oil can be suppressed. Furthermore, in the case of a rotary injection molding machine that supplies hydraulic oil from the center axis side of the rotating disk to the mold clamping device of the rotating disk as in Patent Document 2, a valve device is provided on the center axis side, From there, it seems reasonable to connect the pipe to the mold clamping device from the viewpoint of shortening the overall length of the pipe.

しかしながら特許文献２に記載されたものは回転盤の表面の金型取付位置よりも中心側にバルブ装置が設けられるので金型の取付の際にバルブ装置が邪魔になるものであった。特には水平方向に型開閉されるロータリ式射出成形機のように金型交換時に金型が回転テーブルの型開閉方向に直交する一方向から搬入される場合については、金型が回転テーブルの中心部の前面近傍を通過して取付位置に移動されるので中心側にバルブ装置が設けられていると金型搬入の際の邪魔になるものであった。 However, since the valve device is provided in the center side of the surface of the rotating disk on the center side with respect to the mold mounting position, the valve device becomes an obstacle when mounting the mold. Especially when the mold is loaded from one direction orthogonal to the mold opening / closing direction of the rotary table when the mold is exchanged, such as a rotary injection molding machine that opens and closes in the horizontal direction, the mold is the center of the rotary table. Since it passes through the vicinity of the front surface of the part and is moved to the mounting position, if a valve device is provided on the center side, it will be an obstacle when the mold is loaded.

従って本発明では上記の問題を鑑みて、固定盤に対して可動盤が水平方向に型開閉され、型部材が取付けられる回転テーブルが固定盤または可動盤の一方の盤に回転可能に設けられ、型部材の作動または型部材のクランプに流体を用いるロータリ式射出成形機において、型部材の作動または型部材のクランプにおける応答性の確保、または流体の圧力損失の抑制を図るとともに、金型交換を容易にするロータリ式射出成形機を提供することを目的とする。 Therefore, in the present invention, in view of the above problems, the movable platen is opened and closed horizontally with respect to the fixed platen, and a rotary table to which the die member is attached is provided rotatably on one of the fixed platen or the movable platen, In a rotary injection molding machine that uses fluid to actuate a mold member or clamp the mold member, ensure the responsiveness in the actuation of the mold member or clamp the mold member, or suppress the pressure loss of the fluid, and replace the mold. It is an object of the present invention to provide a rotary injection molding machine that facilitates.

本発明の実施形態のロータリ式射出成形機の概要について図１ないし図４を参照して説明する。本発明のロータリ式射出成形機１１は、ベース１２上の長手方向の一側に設けられた型締装置１３とベース１２上の長手方向の他側に設けられた射出装置１４ａ、１４ｂとから基本的な部分が構成される。そしてロータリ式射出成形機１１は、型締装置１３のベース１２上に固定的に設けられた固定盤１７に対して可動盤１８が水平方向に型開閉され、型部材１５が取付けられる回転テーブル３１が前記固定盤１７または前記可動盤１８の一方の盤に対して回転可能に設けられている。 An outline of a rotary injection molding machine according to an embodiment of the present invention will be described with reference to FIGS. The rotary type injection molding machine 11 of the present invention is basically composed of a mold clamping device 13 provided on one side in the longitudinal direction on the base 12 and injection devices 14 a and 14 b provided on the other side in the longitudinal direction on the base 12. The essential part is composed. In the rotary injection molding machine 11, the movable table 18 is horizontally opened and closed with respect to the fixed plate 17 fixedly provided on the base 12 of the mold clamping device 13, and the rotary table 31 to which the mold member 15 is attached. Is provided to be rotatable with respect to one of the fixed platen 17 and the movable platen 18.

射出装置１４a、１４ｂは公知のものであり、通常はそれぞれ別の材料を射出する目的で射出装置が２本並列状態に設けられている。なお射出装置の配置は、図２に示されたものに限定されず、２本の射出装置のうちの１本の射出装置が型締装置の側方にノズルを金型側に向けて設けられたものや、３本以上の射出装置を有するものなどでもよい。 The injection devices 14a and 14b are well known, and usually two injection devices are provided in parallel for the purpose of injecting different materials. The arrangement of the injection device is not limited to that shown in FIG. 2, and one of the two injection devices is provided on the side of the mold clamping device with the nozzle facing the mold side. Or a device having three or more injection devices.

型締装置１３については、固定盤１７の四隅近傍にはそれぞれ型締機構の型締シリンダ１９が設けられ、その型締シリンダ１９のロッドがそれぞれタイバ２０となっている。従って図３に示されるようにタイバ２０は上下にそれぞれ２本づつが設けられている。型締シリンダ１９は図４に示される油圧装置３７に接続されている。またベース１２上（または固定盤１７）には型開閉機構２１のサーボモータ２２が固定されるとともにボールネジが軸支されている。一方可動盤１８には型開閉機構２１のボールナットが固定され、前記ボールナットにはボールネジが挿通されている。そして可動盤１８は、固定盤１７に対して水平方向に型開閉可能となっている。（図２においては上側となる反操作側Ｂの型開閉機構２１は省略して記載されている。）本発明のように可動盤１８を水平方向に移動させる型締装置１３は、可動盤を垂直方向に昇降させる型締装置との比較において、成形サイクル時間を短縮し消費電力を削減できる場合が多い。なお型締装置はトグル機構等異なる機構を用いたものでもよく、型開閉機構２１も油圧シリンダ等異なる機構のものでもよい。 With respect to the mold clamping device 13, mold clamping cylinders 19 of the mold clamping mechanism are provided in the vicinity of the four corners of the stationary platen 17, and the rods of the mold clamping cylinder 19 serve as tie bars 20. Therefore, as shown in FIG. 3, two tie bars 20 are provided at the top and bottom. The mold clamping cylinder 19 is connected to a hydraulic device 37 shown in FIG. A servo motor 22 of the mold opening / closing mechanism 21 is fixed on the base 12 (or the fixed platen 17), and a ball screw is pivotally supported. On the other hand, a ball nut of a mold opening / closing mechanism 21 is fixed to the movable platen 18, and a ball screw is inserted through the ball nut. The movable platen 18 can be opened and closed in the horizontal direction with respect to the fixed platen 17.

As in the present invention, the mold clamping device 13 that moves the movable platen 18 in the horizontal direction includes the movable platen. In comparison with a mold clamping device that moves up and down in the vertical direction, it is often possible to shorten the molding cycle time and reduce power consumption. The mold clamping device may use a different mechanism such as a toggle mechanism, and the mold opening / closing mechanism 21 may also be a different mechanism such as a hydraulic cylinder.

固定盤１７の射出装置側の面には、前記２本の射出装置１４ａ、１４ｂのノズルが挿入可能な凹状の穴１７ｂが形成されている。図１に示されるように固定盤１７の型部材取付面１７ａの下部側には、型部材１５を水平方向に移動可能な型部材移動機構２４が設けられている。型部材移動機構２４は、水平方向に一列に並んだ複数の転動ローラ２５から構成される。そして前記ローラ２５の上面に金型取付板２３の載置面２３ｂ（下面）が載置可能となっている。 A concave hole 17b into which the nozzles of the two injection devices 14a and 14b can be inserted is formed in the surface of the fixed plate 17 on the injection device side. As shown in FIG. 1, a mold member moving mechanism 24 capable of moving the mold member 15 in the horizontal direction is provided on the lower side of the mold member mounting surface 17 a of the fixed platen 17. The mold member moving mechanism 24 includes a plurality of rolling rollers 25 arranged in a line in the horizontal direction. A mounting surface 23 b (lower surface) of the mold mounting plate 23 can be mounted on the upper surface of the roller 25.

固定盤１７の型部材取付面１７ａの上部側と下部側の２箇所づつには、後述する型部材１５の固定側の固定機構である油圧クランプ機構２７が設けられている。そして金型取付板２３は、合計４箇所の流体を用いて金型取付を行う油圧クランプ機構２７により固定盤１７に固定される。型部材１５の金型取付板２３を固定盤１７に固定する固定機構は、油圧クランプ機構２７以外に、電磁ロック式のクランプ装置、電磁石を用いたマグネットクランプ装置、ボルトにより金型取付板２３を固定する固定機構等でもよい。 A hydraulic clamp mechanism 27 that is a fixing mechanism on the fixing side of the mold member 15 to be described later is provided at two locations on the upper side and the lower side of the mold member mounting surface 17a of the fixed platen 17. The mold mounting plate 23 is fixed to the stationary platen 17 by a hydraulic clamp mechanism 27 that performs mold mounting using a total of four fluids. In addition to the hydraulic clamp mechanism 27, the fixing mechanism for fixing the mold mounting plate 23 of the mold member 15 to the fixing plate 17 is an electromagnetic lock type clamping device, a magnet clamping device using an electromagnet, and a bolt for fixing the mold mounting plate 23 with a bolt. A fixing mechanism for fixing may be used.

可動盤１８については、前記タイバ２０が可動盤１８の四隅近傍の孔にそれぞれ挿通されている。そして可動盤１８の背面の四隅近傍にはハーフナット２８が設けられ、タイバ２０の図示しない係止溝と係合・離脱可能となっている。また可動盤１８の背面側には図示しないエジェクタ機構が設けられている。更に可動盤１８の上面には回転テーブル３１を回転させる回転機構のサーボモータ２９が取付けられている。更にまた可動盤１８の下面側には、ベース１２上を可動盤１８を摺動させるためのガイドブロック３０等が設けられている。 With respect to the movable platen 18, the tie bars 20 are respectively inserted into holes near the four corners of the movable platen 18. Half nuts 28 are provided in the vicinity of the four corners on the back surface of the movable platen 18 so that they can be engaged and disengaged with a locking groove (not shown) of the tie bar 20. An ejector mechanism (not shown) is provided on the back side of the movable platen 18. Further, a servo motor 29 of a rotation mechanism for rotating the rotary table 31 is attached to the upper surface of the movable platen 18. Further, a guide block 30 for sliding the movable plate 18 on the base 12 is provided on the lower surface side of the movable plate 18.

次にロータリ式射出成形機１１の型部材１５について説明すると、本実施形態では２個の固定金型１６ａ，１６ｂが金型取付板２３の前面２３ａにボルト等で固定されている。また２個の回転金型３３ａ，３３ｂが回転テーブル側の金型取付板３４の前面３４ａにボルト等で固定されている。金型取付板２３，３４の下面は、型部材１５が交換の際に搬入される際の載置面２３ｂ，３４ｂとなっている。また型部材１５は、金型取付板２３，３４の表面が後述する油圧クランプ機構２７，３５によりクランプされて固定盤１７や回転テーブル３１に取付けられる。固定側の金型取付板２３には、２本の射出装置１４ａ、１４ｂのノズルが挿入可能な孔またはノズルタッチ面が形成されている。 Next, the mold member 15 of the rotary injection molding machine 11 will be described. In this embodiment, two fixed molds 16a and 16b are fixed to the front surface 23a of the mold mounting plate 23 with bolts or the like. Two rotary molds 33a and 33b are fixed to the front surface 34a of the mold mounting plate 34 on the rotary table side with bolts or the like. The lower surfaces of the mold mounting plates 23 and 34 serve as mounting surfaces 23b and 34b when the mold member 15 is carried in at the time of replacement. The mold member 15 is attached to the stationary platen 17 or the rotary table 31 by clamping the surfaces of the mold attachment plates 23 and 34 by hydraulic clamp mechanisms 27 and 35 described later. Holes or nozzle touch surfaces into which the nozzles of the two injection devices 14a and 14b can be inserted are formed in the fixed-side mold mounting plate 23.

固定金型１６ａ，１６ｂについては、固定側の型部材１５が固定盤１７に固定されたときに操作側Ｃ（図２において型締装置の下側）となる面に温調ホースの接続機器であるカプラのソケット部６３等が設けられている。そのため作業者は、型部材１５を反操作側Ｂから搬入した際に、温調ホース等の取付・取外し作業が操作側Ｃのみから容易にできるようになっている。なお図１等では固定盤側の油圧クランプ機構２７に接続される作動油用ホースやソケット部６３に接続される温調ホースは図示を省略している。 The fixed molds 16a and 16b are connected to a temperature control hose on the surface that becomes the operation side C (the lower side of the mold clamping device in FIG. 2) when the fixed-side mold member 15 is fixed to the fixed platen 17. A coupler socket 63 or the like is provided. Therefore, when the operator carries in the mold member 15 from the non-operation side B, the operator can easily attach / remove the temperature control hose or the like only from the operation side C. In FIG. 1 etc., the hydraulic oil hose connected to the hydraulic clamp mechanism 27 on the fixed platen side and the temperature control hose connected to the socket part 63 are not shown.

回転金型３３ａ，３３ｂについても、回転金型３３ａ，３３ｂが交換され金型取付板３４を介して回転テーブル３１に固定されるときに操作側Ｃとなる面に、温調ホースの接続機器であるカプラのソケット部６２，６２とコア部５３ａ，５３ｂを作動させる油圧シリンダ５４ａ，５４ｂの接続用配管５６ａ，５６ｂの接続機器であるカプラのソケット部６３，６３が設けられている。すなわち型部材交換時に型部材が挿入される側と反対側の面の操作側Ｃの面に前記温調ホースの接続機器と前記接続用配管５６ａ，５６ｂの接続機器が設けられることにより、作業者によるホースや配管の取付・取外し作業が容易となっている。なお回転金型３３ａ，３３ｂおよび固定金型１６ａ，１６ｂについては、別の側面に温調ホースの接続機器と作動油の配管の接続機器が設けられるものを除外するものではない。 The rotary molds 33a and 33b are also connected to a temperature control hose connecting device on the surface which becomes the operation side C when the rotary molds 33a and 33b are exchanged and fixed to the rotary table 31 via the mold mounting plate 34. Coupler socket parts 63, 63, which are connecting devices for connecting pipes 56a, 56b of hydraulic cylinders 54a, 54b for operating the socket parts 62, 62 of the coupler and the core parts 53a, 53b, are provided. In other words, the temperature control hose connection device and the connection pipes 56a and 56b are provided on the operation side C of the surface opposite to the side where the mold member is inserted when the mold member is replaced. This makes it easy to install and remove hoses and pipes.

A temperature control pipe 59 for supply and a temperature control pipe 60 for discharge are connected from the relay box 58 to the rotary molds 33a and 33b. Note that the mold member 15 may be carried out and carried into the rotary injection molding machine 11 from between the upper and lower tie bars 20 and 20 on the operation side C. In this case, the rotary table is used to replace the mold. It is desirable that a fluid valve or the like is disposed at a position that becomes the non-operation side B when 31 is stopped. That is, when carrying in / out of the mold member 15 from the operation side C, the right side of the mold member moving mechanism 38 provided on the surface 31a of the turntable 31 in the same view as in FIG. A fluid valve or the like is disposed in the front.

Is done.

型部材交換機構４１については、ロータリ式射出成形機１１の側方（ここでは反操作側Ｂ）には、レール４８が2本設けられ、前記レール４８の上を型部材交換台車４９が移動機構である油圧シリンダ６４等により型開閉方向に移動可能となっている。型部材交換台車４９は、成形の終了した型部材１５を降ろす搬出ステージ５０と、次回に成形を行う型部材１５を載置しておく搬入ステージ５１とが設けられている。 As for the mold member replacement mechanism 41, two rails 48 are provided on the side of the rotary injection molding machine 11 (here, the non-operation side B), and the mold member replacement carriage 49 moves on the rail 48. It can be moved in the mold opening and closing direction by a hydraulic cylinder 64 or the like. The mold member exchange carriage 49 is provided with a carry-out stage 50 for lowering the molded mold member 15 and a carry-in stage 51 for placing the mold member 15 to be molded next time.

次にロータリ式射出成形機１１の型部材１５の交換方法について説明する。図２に示されるように型部材交換台車４９は成形の完了した型部材１５を降ろす搬出ステージ５０が、型閉時の固定盤１７と可動盤１８の間に正対する台車の型部材交換位置（搬出位置）に停止されている。また搬出ステージ５０の隣の搬入ステージ５１には次回の成形に使用する型部材１５が載置されている。そして連続成形が終了して作業者がロータリ式射出成形機１１の操作盤において型部材交換モードを選択した際に、図３に示されるように型部材移動機構３８が他方の固定盤１７の型部材移動機構２４と対向する状態となるように回転テーブル３１を位置決め停止させる。次に可動盤１８が前進され、固定金型１６ａ，１６ｂに対して回転金型３３ａ，３３ｂが型閉される。この状態で成形の終了した回転金型３３，３３ｂに接続されていた温調配管５９，６０等と、金型部材の作動機構の接続用配管５６ａ，５６ｂの接続を取り外す。また固定金型１６ａ，１６ｂも同様に温調配管等の取外しを行う。 Next, a method for replacing the mold member 15 of the rotary injection molding machine 11 will be described. As shown in FIG. 2, the mold member replacement carriage 49 has a carriage mold member replacement position where the unloading stage 50 for lowering the molded mold member 15 faces the gap between the fixed platen 17 and the movable platen 18 when the mold is closed ( Stopped at the unloading position). A mold member 15 used for the next molding is placed on the carry-in stage 51 next to the carry-out stage 50. When the continuous molding is completed and the operator selects the mold member replacement mode on the operation panel of the rotary injection molding machine 11, the mold member moving mechanism 38 moves the mold of the other stationary platen 17 as shown in FIG. The rotary table 31 is positioned and stopped so as to face the member moving mechanism 24. Next, the movable platen 18 is advanced, and the rotating dies 33a and 33b are closed with respect to the fixed dies 16a and 16b. In this state, the connection between the temperature control pipes 59, 60 and the like connected to the rotary molds 33, 33b that have been molded and the connection pipes 56a, 56b of the operating mechanism of the mold member is removed. Similarly, the fixed molds 16a and 16b also remove the temperature control piping and the like.

次に固定盤１７の油圧クランプ機構２７による金型取付板２３のクランプを停止する。また同時に回転テーブル３１が取付けられた可動盤側の型部材のクランプ機構である油圧クランプ機構３５の油圧シリンダ６５による金型取付板３４のクランプを停止する。そして次に可動盤１８をごく僅かに型開側に移動させる。このことにより固定盤１７の型部材取付面１７ａと金型取付板２３との間に僅かに間隙が形成され、回転テーブル３１の表面３１ａと金型取付板３４の間にも僅かに間隙が形成される。なお温調ホース等の接続部材を外す手順やクランプを解除する手順は前記したものに限定されない。 Next, the clamping of the mold mounting plate 23 by the hydraulic clamp mechanism 27 of the fixed platen 17 is stopped. At the same time, the clamping of the mold mounting plate 34 by the hydraulic cylinder 65 of the hydraulic clamping mechanism 35 which is a clamping mechanism of the mold member on the movable platen side to which the rotary table 31 is mounted is stopped. Then, the movable platen 18 is moved to the mold opening side very slightly. As a result, a slight gap is formed between the mold member mounting surface 17a of the fixed platen 17 and the mold mounting plate 23, and a slight gap is also formed between the surface 31a of the rotary table 31 and the mold mounting plate 34. Is done. The procedure for removing the connecting member such as the temperature control hose and the procedure for releasing the clamp are not limited to those described above.

次に型部材交換台車４９の油圧シリンダ等を作動させ、搬出ステージに成形後の型部材１５を搬出する。また型部材交換台車４９の搬入ステージ５１を固定盤１７と可動盤１８の間に正対する位置に移動させ、次回に成形機に取付けられる型部材１５をロータリ式射出成形機１１の型締装置１３に向けて移動させる。この際型部材１５は反操作側Ｂから上下のタイバ２０，２０間を通過して搬入される。そして型部材１５は、搬入ステージ５１の転動ローラの上から固定盤１７に設けられた型部材移動機構２４の転動ローラ２５と可動盤１８の回転テーブル３１に設けられた型部材移動機構３８の転動ローラ３９の上に移動される。この際型部材１５は、水平方向かつ型開閉方向と直交する方向に移動される。この移動の際の型部材１５の金型取付板３４の裏面と回転テーブル３１の表面３１ａの間の距離は、転動ローラ３９に金型取付板３４の載置面３４ｂが載置される必要があることからごく僅かである。 Next, the hydraulic cylinder of the mold member exchange carriage 49 is operated, and the molded mold member 15 is carried out to the carry-out stage. Further, the carry-in stage 51 of the mold member exchange carriage 49 is moved to a position facing the fixed platen 17 and the movable platen 18, and the mold member 15 to be attached to the molding machine next time is used as the mold clamping device 13 of the rotary injection molding machine 11. Move towards. At this time, the mold member 15 is carried from the non-operation side B through the upper and lower tie bars 20 and 20. The mold member 15 is placed on the rolling roller 25 of the mold member moving mechanism 24 provided on the stationary platen 17 and the mold member moving mechanism 38 provided on the rotary table 31 of the movable platen 18 from above the rolling roller of the carry-in stage 51. Is moved onto the rolling roller 39. At this time, the mold member 15 is moved in the horizontal direction and in a direction orthogonal to the mold opening / closing direction. The distance between the back surface of the mold mounting plate 34 of the mold member 15 and the front surface 31a of the rotary table 31 during this movement is such that the mounting surface 34b of the mold mounting plate 34 is mounted on the rolling roller 39. There is very little because there is.

そして型部材１５の金型取付板３４の前端が回転テーブル３１の回転中心Ｏの位置を通過した後にストッパ部材４４に当接されると、エアシリンダ３６が前進され、回転テーブル３１に対する型部材１５の水平方向の位置決めがなされる。次に型開閉機構２１の作動により可動盤１８と回転テーブル３１が僅かに前進されて、固定盤１７の型部材取付面１７ａと金型取付板２３の間が完全に密着される。また同時に回転テーブル３１の表面３１ａと金型取付板３４の間の間隙は完全に解消され両者は密着される。 When the front end of the mold mounting plate 34 of the mold member 15 passes through the position of the rotation center O of the rotary table 31 and is brought into contact with the stopper member 44, the air cylinder 36 is advanced, and the mold member 15 with respect to the rotary table 31 is moved forward. Are positioned in the horizontal direction. Next, the movable platen 18 and the rotary table 31 are slightly moved forward by the operation of the mold opening / closing mechanism 21, and the mold member mounting surface 17a of the fixed platen 17 and the mold mounting plate 23 are completely brought into close contact with each other. At the same time, the gap between the surface 31a of the rotary table 31 and the mold mounting plate 34 is completely eliminated and the two are brought into close contact with each other.
