上記従来の模型定盤固定装置では、複数のシリンダを設置するスペースをキャリアプレートに設けなければならず、キャリアプレートが大型化するとともに、模型定盤の交換時にラムを進退させるためにシリンダに圧力流体を供給しなければならず、シリンダを圧力流体供給装置に接離可能としなければならない。また下盛枠が上下動可能に嵌装されたキャリアプレートの周囲に、複数のシリンダを装着することは困難である。   In the above conventional model surface plate fixing device, a space for installing a plurality of cylinders must be provided in the carrier plate, and the carrier plate becomes large and pressure is applied to the cylinders to advance and retract the ram when the model surface plate is replaced. Fluid must be supplied and the cylinder must be capable of contacting and leaving the pressure fluid supply device. In addition, it is difficult to mount a plurality of cylinders around the carrier plate in which the lower frame is fitted so as to be movable up and down.

本発明は、かかる従来の不具合を解消するためになされたもので、模型定盤が着脱されるキャリアプレートに着脱用アクチュエータを設けることなく、構造が簡単で省スペースの鋳型造型用模型定盤固定装置を提供することである。   The present invention has been made to solve such a conventional problem, and has a simple structure and space-saving model plate mounting for mold making without providing an attaching / detaching actuator on a carrier plate to which the model plate is attached / detached. Is to provide a device.

上記の課題を解決するため、請求項１に係る発明の構成上の特徴は、鋳型造型装置のスクイズテーブルに載置されるキャリアプレートに模型定盤を着脱可能に固定する鋳型造型用模型定盤固定装置において、キャリアプレートに水平回動軸回りに回動可能に支承され係合部が前記模型定盤に形成された当接部に係脱して前記模型定盤を前記キャリアプレートに着脱可能に固定するクランプ部材と、前記係合部が前記当接部と係合するクランプ方向に前記クランプ部材を回動させるばね部材と、前記キャリアプレートと別体に設けられ前記クランプ部材を前記ばね部材のばね力に抗して前記係合部が前記当接部から離脱するアンクランプ方向に回動させる押動装置とを備え、前記クランプ部材が前記ばね部材のばね力によって前記クランプ方向に回動されると、前記係合部と前記当接部とが係合し、前記模型定盤が前記キャリアプレートに締結されることである。   In order to solve the above-described problems, the structural feature of the invention according to claim 1 is that a model surface plate for mold making that detachably fixes a model surface plate to a carrier plate placed on a squeeze table of a mold making device. In the fixing device, the model platen can be attached to and detached from the carrier plate by being supported by the carrier plate so as to be rotatable about a horizontal rotation axis, and the engaging part being engaged with and disengaging from the contact part formed on the model platen. A clamping member to be fixed; a spring member that rotates the clamping member in a clamping direction in which the engaging portion engages with the abutting portion; and a clamp member that is provided separately from the carrier plate. A pushing device that rotates in an unclamping direction in which the engaging part is separated from the abutting part against a spring force, and the clamping member is moved in the clamping direction by a spring force of the spring member. Once rotated, the engaging portion and the abutment portion and engages, is that the model plate is fastened to the carrier plate.

請求項２に係る発明の構成上の特徴は、請求項１において、前記当接部の上面に、前記クランプ部材の回動方向手前から奥に向かって水平面に対して上方に僅かに傾斜する傾斜面が形成され、前記クランプ部材が前記ばね部材のばね力によって前記クランプ方向に回動されると、前記係合部は前記当接部の上面に形成された傾斜面に前記クランプ部材の水平回動軸の上方で係合することである。   The structural feature of the invention according to claim 2 is that in claim 1, the upper surface of the abutting portion is slightly inclined upward with respect to the horizontal plane from the front to the back in the rotational direction of the clamp member. When the clamp member is rotated in the clamping direction by the spring force of the spring member, the engagement portion is rotated horizontally on the inclined surface formed on the upper surface of the contact portion. Engage above the dynamic shaft.

請求項３に係る発明の構成上の特徴は、請求項１又は２において、前記傾斜面の水平面に対する傾斜角は、前記係合部と前記傾斜面との間の静摩擦角より小さいことである。   The structural feature of the invention according to claim 3 is that, in claim 1 or 2, the inclination angle of the inclined surface with respect to the horizontal plane is smaller than the static friction angle between the engaging portion and the inclined surface.

上記のように構成した請求項１に係る発明においては、ばね部材のばね力によるクランプ部材のクランプ方向の回動により、クランプ部材の係合部が模型定盤に形成された当接部と係合し、前記模型定盤がキャリアプレートに締結される。キャリアプレートと別体に設けられた押動装置によりクランプ部材がばね部材のばね力に抗してアンクランプ方向に回動されると、クランプ部材の係合部が当接部から離脱される。   In the invention according to claim 1 configured as described above, the engaging portion of the clamp member is engaged with the contact portion formed on the model surface plate by the rotation of the clamp member in the clamping direction by the spring force of the spring member. The model surface plate is fastened to the carrier plate. When the clamp member is rotated in the unclamping direction against the spring force of the spring member by the pushing device provided separately from the carrier plate, the engaging portion of the clamp member is released from the contact portion.

これにより、キャリアプレートにアクチュエータを設けることなく小型かつ簡素な構成で模型定盤を確実にキャリアプレートに着脱可能に固定することができる。   Thereby, a model surface plate can be reliably detachably fixed to the carrier plate with a small and simple configuration without providing an actuator on the carrier plate.

上記のように構成した請求項２に係る発明においては、前記当接部の上面に形成された傾斜面は、クランプ部材の回動方向手前から奥に向かって水平面に対して上方に僅かに傾斜しているので、クランプ部材のクランプ方向の回動により、係合部はクランプ部材の水平回動軸の上方で傾斜面と確実に係合することができる。そして、傾斜面の傾斜角度が小さく、クランプ部材がばね部材のばね力によってクランプ方向に付勢されているので、模型定盤をキャリアプレートから上方に離脱させる方向に作用する外力が増大しても、それにつれて係合部と傾斜面との間の傾斜面方向の摩擦力も大きくなるので、クランプ部材がアンクランプ方向に回動することはなく、模型定盤はキャリアプレートに堅固にクランプされる。   In the invention which concerns on Claim 2 comprised as mentioned above, the inclined surface formed in the upper surface of the said contact part inclines slightly upwards with respect to a horizontal surface toward the back from the rotation direction front of a clamp member. Therefore, the engagement portion can be reliably engaged with the inclined surface above the horizontal rotation axis of the clamp member by the rotation of the clamp member in the clamping direction. And since the inclination angle of the inclined surface is small and the clamp member is biased in the clamping direction by the spring force of the spring member, even if the external force acting in the direction of detaching the model platen upward from the carrier plate increases Accordingly, the frictional force in the inclined surface direction between the engaging portion and the inclined surface also increases, so that the clamp member does not rotate in the unclamping direction, and the model platen is firmly clamped to the carrier plate.

上記のように構成した請求項３に係る発明においては、傾斜面の水平面に対する傾斜角は、前記係合部と前記傾斜面との間の静摩擦角より小さいので、模型定盤をキャリアプレートから上方に離脱させる方向に作用する外力によって、クランプ部材がアンクランプ方向に回動することはない。   In the invention according to claim 3 configured as described above, since the inclination angle of the inclined surface with respect to the horizontal plane is smaller than the static friction angle between the engaging portion and the inclined surface, the model surface plate is moved upward from the carrier plate. The clamp member does not rotate in the unclamping direction due to the external force acting in the direction of detachment.

以下本発明の実施の形態に係る鋳型造型用模型定盤固定装置を図面に基づいて説明する。図１において、キャリアプレート１には、模型２が取付けられた模型定盤３が着脱可能に固定されるとともに、下盛枠４が上下動可能に嵌合されている。キャリアプレート１は、鋳型造型装置５のスクイズテーブル６上に載置され、上昇された下盛枠４上に鋳枠７が載置され、該鋳枠７内に鋳物砂８が充填され、その状態でスクイズテーブル６が上昇されて鋳物砂８がスクイズヘッド９により背面側からスクイズされ、次に鋳枠７のスクイズヘッド９に対する上昇がストップシリンダ１０により阻止された状態でスクイズテーブル６が上昇されて鋳物砂８が模型面側からスクイズされる。   DESCRIPTION OF EMBODIMENTS Hereinafter, a mold making model surface plate fixing apparatus according to an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, a model platen 3 to which a model 2 is attached is detachably fixed to a carrier plate 1 and a lower frame 4 is fitted in a vertically movable manner. The carrier plate 1 is placed on the squeeze table 6 of the mold making apparatus 5, the casting frame 7 is placed on the raised lower frame 4, and the foundry sand 8 is filled in the casting frame 7. In this state, the squeeze table 6 is raised and the foundry sand 8 is squeezed from the back side by the squeeze head 9, and then the squeeze table 6 is raised in a state where the rise of the casting frame 7 relative to the squeeze head 9 is blocked by the stop cylinder 10. The foundry sand 8 is squeezed from the model surface side.

図２に示すように、キャリアプレート１は仕切壁１１により上下に仕切られた矩形筒状体をなし、上方に開口する矩形穴１２には模型定盤３が一対の位置決めピンにより位置決めされ且つ上面が同一平面となるように嵌合され、キャリアプレート１の両側に設けられた鋳型造型用模型定盤固定装置１３により着脱可能に固定されている。   As shown in FIG. 2, the carrier plate 1 has a rectangular cylindrical body that is partitioned up and down by a partition wall 11, and the model surface plate 3 is positioned by a pair of positioning pins in a rectangular hole 12 that opens upward, and the upper surface. Are fitted so as to be in the same plane, and are detachably fixed by a mold making model surface plate fixing device 13 provided on both sides of the carrier plate 1.

両側の鋳型造型用模型定盤固定装置１３は同一構成であるので、片側の装置１３について以下に説明する。図２、図３に示すように、キャリアプレート１の側壁１４には、仕切壁１１の上方から下面に向かって縦長の凹部１５が形成されている。凹部１５の両側壁１６に形成された横溝１８には、クランプ部材２０を支承する水平軸１７の両端が係入され、ボルト１９によって固定されている。これにより、クランプ部材２０はキャリアプレート１に水平回動軸回りに回動可能に支承されている。クランプ部材２０の上端には、係合部２１がキャリアプレート１に向かって突設されている。模型定盤３の側面には、模型定盤３が矩形穴１２に嵌合されて位置決めされたとき係合部２１と対向する位置に当接部材２２が当接部として固定されている。クランプ部材２０の下端部とキャリアプレート１の凹部１５の垂直底壁との間には、係合部２１が当接部材２２と係合するクランプ方向にクランプ部材２０を回動させる圧縮スプリング２４（ばね部材）が介在されている。圧縮スプリング２４の両端は、クランプ部材２０の下端部と凹部１５の垂直底壁との対向面に形成されたばね座穴に遊嵌されて保持されている。   Since the mold making model surface plate fixing devices 13 on both sides have the same configuration, the device 13 on one side will be described below. As shown in FIGS. 2 and 3, a longitudinally long recess 15 is formed on the side wall 14 of the carrier plate 1 from the upper side to the lower side of the partition wall 11. Both ends of the horizontal shaft 17 that supports the clamp member 20 are engaged with the lateral grooves 18 formed in the both side walls 16 of the recess 15 and are fixed by bolts 19. Thus, the clamp member 20 is supported on the carrier plate 1 so as to be rotatable about a horizontal rotation axis. At the upper end of the clamp member 20, an engaging portion 21 protrudes toward the carrier plate 1. On the side surface of the model surface plate 3, a contact member 22 is fixed as a contact portion at a position facing the engagement portion 21 when the model surface plate 3 is fitted into the rectangular hole 12 and positioned. Between the lower end of the clamp member 20 and the vertical bottom wall of the concave portion 15 of the carrier plate 1, a compression spring 24 (rotating the clamp member 20 in the clamping direction in which the engaging portion 21 engages with the contact member 22 ( A spring member) is interposed. Both ends of the compression spring 24 are loosely fitted and held in spring seat holes formed on the opposing surfaces of the lower end portion of the clamp member 20 and the vertical bottom wall of the recess 15.

当接部材２２の上面には、クランプ部材２０の回動方向手前から奥に向かって水平面に対して上方に僅かに傾斜する傾斜面２３が形成されている。傾斜面２３の水平面に対する傾斜角は、係合部２１と傾斜面との静摩擦角より小さいことが好ましい。そして、クランプ部材２０が圧縮スプリング２４のばね力によってクランプ方向に回動されると、係合部２１が傾斜面２３に水平軸１７、即ちクランプ部材２０の水平回動軸の上方で係合するように、係合部２１、傾斜面２３及び水平軸１７が配置されている。これにより、クランプ部材２０のクランプ方向の回動により、係合部２１はクランプ部材２０の水平回動軸の上方で傾斜面２３と確実に係合することができる。そして、傾斜面２３の傾斜角度が小さく、クランプ部材２０が圧縮スプリング２４のばね力によってクランプ方向に付勢されているので、模型定盤３をキャリアプレート１から上方に離脱させる方向に作用する外力が増大しても、それにつれて係合部２１と傾斜面２３との間の傾斜面方向の摩擦力も大きくなるので、クランプ部材２０がアンクランプ方向に回動することはなく、模型定盤３がキャリアプレート１に堅固にクランプされている。傾斜面２３の水平面に対する傾斜角を、係合部２１と傾斜面２３との間の静摩擦角より小さくすると、模型定盤３をキャリアプレート１から上方に離脱させる方向に作用する外力によって、クランプ部材２０がアンクランプ方向に回動することを確実に防ぐことができる。   On the upper surface of the contact member 22, an inclined surface 23 that is slightly inclined upward with respect to the horizontal plane is formed from the front of the clamping member 20 toward the back. The inclination angle of the inclined surface 23 with respect to the horizontal plane is preferably smaller than the static friction angle between the engaging portion 21 and the inclined surface. When the clamp member 20 is rotated in the clamping direction by the spring force of the compression spring 24, the engaging portion 21 is engaged with the inclined surface 23 above the horizontal shaft 17, that is, above the horizontal rotation shaft of the clamp member 20. Thus, the engaging part 21, the inclined surface 23, and the horizontal axis | shaft 17 are arrange | positioned. Thereby, the engagement part 21 can be reliably engaged with the inclined surface 23 above the horizontal rotation axis of the clamp member 20 by the rotation of the clamp member 20 in the clamping direction. And since the inclination angle of the inclined surface 23 is small and the clamp member 20 is urged in the clamping direction by the spring force of the compression spring 24, the external force acting in the direction of detaching the model surface plate 3 from the carrier plate 1 upward. Accordingly, the frictional force in the direction of the inclined surface between the engaging portion 21 and the inclined surface 23 also increases accordingly, so that the clamp member 20 does not rotate in the unclamping direction, and the model surface plate 3 The carrier plate 1 is firmly clamped. When the inclination angle of the inclined surface 23 with respect to the horizontal plane is made smaller than the static friction angle between the engaging portion 21 and the inclined surface 23, the clamp member is caused by an external force acting in a direction in which the model surface plate 3 is detached from the carrier plate 1 upward. It is possible to reliably prevent the 20 from rotating in the unclamping direction.

２５は、クランプ部材２０を圧縮スプリング２５のばね力に抗してアンクランプ方向に回動させる押動装置としてのシリンダ装置で、キャリアプレート１に固定された模型定盤３を取替えるためにキャリアプレート１が載置される載置台２８の上面にクランプ部材２０の背面に対向して固定されている。クランプ部材２０は、シリンダ装置２５のピストンロッド２６により下端背面を押動されて、アンクランプ方向に回動され、係合部２１が当接部材２２から離脱すると、下端内側に突設された停止部が、凹部１５の垂直底壁に固定されたストップ部材２７と当接してアンクランプ位置に停止される。   Reference numeral 25 denotes a cylinder device as a pushing device for rotating the clamp member 20 in the unclamping direction against the spring force of the compression spring 25. The carrier plate is used to replace the model surface plate 3 fixed to the carrier plate 1. 1 is fixed to the upper surface of the mounting table 28 on which the 1 is mounted facing the back surface of the clamp member 20. The clamp member 20 is pushed in the back of the lower end by the piston rod 26 of the cylinder device 25 and is rotated in the unclamping direction. The portion comes into contact with a stop member 27 fixed to the vertical bottom wall of the recess 15 and is stopped at the unclamping position.

上記のように構成した実施の形態に係る鋳型造型用模型定盤固定装置１３の作動を説明する。模型定盤３を取替える場合、キャリアプレート１は載置台２８の所定位置に載置される。図４に示すように、シリンダ装置２５のピストンロッド２６が前進され、クランプ部材２０の背面が圧縮スプリング２４のばね力に抗して押動され、係合部２１が当接部材２２から離脱するアンクランプ方向に各クランプ部材２０が回動される。アンクランプされた模型定盤３がキャリアプレート１の矩形穴１２から取外され、新たに装着する模型定盤３が、下端面に穿設された位置決め穴と仕切壁１１に立設された一対の位置決めピンとの嵌合により位置決めされて矩形穴１２内に嵌め込まれる。   The operation of the mold making model surface plate fixing device 13 according to the embodiment configured as described above will be described. When the model surface plate 3 is replaced, the carrier plate 1 is placed at a predetermined position on the placement table 28. As shown in FIG. 4, the piston rod 26 of the cylinder device 25 is advanced, the back surface of the clamp member 20 is pushed against the spring force of the compression spring 24, and the engaging portion 21 is detached from the contact member 22. Each clamp member 20 is rotated in the unclamping direction. The unclamped model surface plate 3 is removed from the rectangular hole 12 of the carrier plate 1, and the newly mounted model surface plate 3 is a pair of standing holes provided on the lower end surface and the partition wall 11. It is positioned by fitting with the positioning pin and is fitted into the rectangular hole 12.

次に、シリンダ装置２５のピストンロッド２６が後退されると、クランプ部材２０は、係合部２１がクランプ部材２０の水平回動軸の上方で傾斜面２３と係合するまで圧縮スプリング２４のばね力によりクランプ方向に回動され、模型定盤３をキャリアプレート１の仕切壁１１に押付けて固定する。このとき、傾斜面２３の水平面に対する傾斜角が小さいので、模型定盤３をキャリアプレート１から上方に離脱させる方向に作用する外力によって、クランプ部材２０がアンクランプ方向に回動することはなく、模型定盤３はキャリアプレート１に堅固にクランプされる。   Next, when the piston rod 26 of the cylinder device 25 is retracted, the clamp member 20 moves the spring of the compression spring 24 until the engaging portion 21 engages with the inclined surface 23 above the horizontal rotation axis of the clamp member 20. It is rotated in the clamping direction by force, and the model surface plate 3 is pressed against the partition wall 11 of the carrier plate 1 and fixed. At this time, since the inclination angle of the inclined surface 23 with respect to the horizontal plane is small, the clamping member 20 does not rotate in the unclamping direction due to an external force acting in a direction of detaching the model surface plate 3 upward from the carrier plate 1. The model surface plate 3 is firmly clamped to the carrier plate 1.
