Description

【0001】
【発明の属する技術分野】
この発明は、射出成形機などの成形機が備える型締装置の固定盤又は可動盤に取付けた金型の落下防止に関するものである。
【0002】
【発明が解決しようとする課題】
通常構造の成形機における金型の取付は、固定盤や可動盤に固着した型取付板に金型をボルト止めするか、またはクランプするかして行っている。また最近では型取付板をマグネット板により構成して金型を磁着するものもあるが、ボルト止めを除いて、それらの取付手段では事故により金型が落下する虞がある。
【0003】
例えば、クランプによる場合には、その殆どが油圧シリンダを採用してクランプの締付けを行っているが、横型の型締装置では下側に機台があるために、クランプ装置の配置が両側に制限され、下側を支えるクランプ装置がないことから、油圧回路の油漏れにより圧力が低下して締付力が弱まると、金型が自重によりスリップして落下することがある。
またマグネット板による場合には、通電による励磁により生じた磁力が減衰して、金型重量よりも磁着力が弱くなると金型が落下するようになる。
【0004】
したがって、落下防止の上ではボルト止めによる取付が最も好ましいのであるが、ボルト止めは手作業となることから、クランプや磁着に比べて金型の交換作業に手数と時間とを要し、また自動化にも不適当なために現状での取付は、油圧作動のクランプによるものが圧倒的に多い。
【0005】
この発明の目的は、上記クランプやマグネット板等による場合の金型落下の課題を解決し、また各種の取付手段との併用が可能で型取付板と金型との結合も容易に行え、金型寸法が異なっても金型の落下を確実に防止し得ることは勿論のこと、金型中心とノズル位置との位置合わせも簡単に行い得る新たな成形機の金型落下防止方法を提供することにある。
【0006】
【課題を解決するための手段】
上記目的によるこの発明は、機台上の固定盤又は可動盤の型取付板と、その型取付板にクランプ又は磁着等により止着される金型の当接面の両方に、互いに位置を同じくして両側端から面内中央に、底部を拡大形成して凹設した少なくとも左右一対のキー溝と、その型取付板のキー溝と金型のキー溝の重合により形成された孔部に、型取付板の側端面から挿入嵌合されて、該型取付板と金型を一体的に結合するキー部材と、型取付板の側端面にキー溝に隣接して回動自在に軸設し、ばね部材により常時キー溝の開口端に弾圧位置させた止め金具とからなり、上記キー部材の長さを型取付板のキー溝と同一長さにし、そのキー部材を型取付板の側端面からキー溝に挿入嵌合して、キー部材の外端面を型取付板の側端面に位置させ、その外端面を上記止め金具により受け止めてキー部材の抜け出しを阻止し、金型の落下を防止してなる、というものである。
【0007】
またこの発明は、上記成形機の金型落下防止方法において、上記型取付板と金型の両方の当接面の両側と下側の三方の中央に、上記キー溝を側端面と下端面から面内中央へと互いに位置を同じくして凹設し、そのキー溝の重合により形成された孔部に、型取付板の側端面と下端面からそれぞれキー溝に挿入して嵌合したキー部材の外端面を、型取付板の側端面と下側端面とにキー溝に隣接して回動自在に軸設し、常時キー溝の開口端に位置させた止め金具により受け止めて、キー部材の抜け出しを阻止し、それらのキー溝及びキー部材により、金型中心を金型寸法の大小にかかわらずノズル位置に設定できるようにしてなる、というものである。
【0008】
上記キー溝としては、型取付板と金型を結合して金型の前側への抜け倒れを防止する係合面を有する断面形状が好ましい。たとえば、両方のキー溝の重合により形成される孔部の断面形状が、杵形状、亜鈴状形などで、キー部材もまたそれらの形状に適合する断面形状で長尺のものが用いられる。
【0009】
【発明の実施の形態】
図中1は機台2の上に設置された固定盤で、図では省略したが、可動盤と対面する内側面に鋼鉄等の強磁性体による型取付板3を有する。この型取付板3の内側には励磁コイルが仕込まれていて、通電によりマグネット板として金型4を磁着することができるように構成されている。
【0010】
この型取付板3の上記金型4との当接面には、底部が拡大形成された蟻溝状のキー溝5が、両側端3a,3aと下側端3bの三方の中央から面内中央へと凹設してある。また金型4の型取付板3との当接面にも、底部が拡大形成された蟻溝状のキー溝6が、両側端4a,4aと下側端及び上側端4b,4bの四方の中央から面内中央へと、型取付板側のキー溝5と互いに位置を同じくして凹設してある。
この下側端3b,4bのキー溝5,6は、両側端3a,4aのキー溝5,6と、それらに挿入嵌合したキー部材7とによって、金型4の中心を金型寸法の大小にかかわらずノズル位置に設定するものであるので、図では省略したが、上側に同様に設けてもよい。また金型4の落下防止としては、両側端3a,4aの一対のみで、その目的を十分に達成し得ることは云うまでもない。
【0011】
上記キー部材7は、上記キー溝5,6の重合により形成された断面形状が杵状形の孔部8(図2参照)と同一断面形状のものからなる。このキー部材7は型取付板3のキー溝5と同一長さ寸法で外端にストッパー9が突設してある。
【0012】
10は板状の止め金具で、型取付板3の側端面3aに上記キー溝5の開口端を塞ぐように一端部をねじピン11により回動自在に止着して設けられている。この止め金具10と側端面3aとの間には、ばね部材12が止め金具10を当接面側に弾圧するように、上記ねじピン11の周囲に挿通して設けてあり、このばね部材12によって止め金具10は常にキー溝5の開口端に位置している。なお13は止め金具10の摘みを示す。
【0013】
図4は、型取付板3の両側上下に設けた油圧作動のクランプ装置14,14により、金型4を上記固定盤1又は可動盤(図は省略)に取付けた場合の実施形態を示すものである。このように型取付手段が異なっても、クランプ装置14,14の設置位置が両側上下となることから、上記キー溝5はマグネット板を型取付板3として図1に示す実施形態と同様に、型取付板3の両側中央と下側中央との3箇所に凹設することができ、また金型4の当接面のキー溝6の凹設位置も変更を要せず、そのままの状態で型取付板3の当接面の上記キー溝5に重合させて、上記キー部材7を挿入する上記孔部8を形成することができる。
【0014】
上記キー溝5,6とキー部材7及び止め金具10による金型4の落下防止は、搬入した金型4と型取付板3との位置合わせを行ってから施される。この位置合わせにより双方のキー溝5,6が互いに重なって上記孔部8を形成するので、その孔部8にキー部材7を型取付板3の側面のキー溝5の開口端に嵌め込んで挿入するだけの簡単な操作で行い得る。
【0015】
また図示のように、型取付板3と金型4の下側端3b,4bとにキー溝5,6を凹設して、左右両側のものとにより金型4の取付を三方にて行う場合には、それらに挿入したキー部材7により、金型4の中心が固定盤中心のノズル位置20と必然的に一致するようになる。
【0016】
このキー部材7の挿入に際しては、キー溝5の開口端は上記ばね部材12により常に弾圧された止め金具10により塞がれた状態にあるので、この止め金具10を回動して開口端の脇にずらしてからキー部材7の挿入を行うことになる。またキー部材7が充分に押し込まれて外端面が型取付板3の側端面3aと面一となると、キー部材7により戻りを阻止されていた止め金具10が、ばね部材12により元に戻されて外端面から突出した上記ストッパー9に当たり、その外端面の下側を横切る覆いとなってキー部材7の抜け出しを阻止する。このため挿入後のキー部材7は止め金具10を人為的に回動してその外端面から除かない限り、型取付板3と金型4の両方のキー溝5,6に嵌り込んで一体に結合している。
【0017】
このようなキー溝5,6とキー部材7とにより型取付板3に結合された金型4では、通電による励磁により生じた磁力が減衰して、金型重量よりも磁着力が弱くなって金型4の拘束力を失ったり、あるいはクランプによる締付力の低下から金型4の固定に緩みが生じるなどして、金型4が自重により型取付板3をスリップして落下するような事態が生じても、その落下はキー部材7によって防止される。またキー溝5,6の底部の拡大により形成された係合面によって、型取付板3からの金型4の前倒れも防止されるようになる。
【0018】
金型交換の際には、上記止め金具10を回動して脇にずらせてからキー部材7を抜き出すだけでよいので、その取扱は極めて簡単である。また型取付板3のキー溝5の長さを、最小の金型寸法に合わせてキー部材7と共に予め長く設定しておけば、金型寸法の大小に左右されずそのまま適用でき、固定盤側では金型中心を金型寸法の大小にかかわらずノズル位置に設定し得るので、多種仕様の金型の交換が要求される成形機にとっても作業上の煩わしさは少なく、金型寸法が異なっても落下を確実に防止し得るなどの多くの利点を有する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to preventing a mold attached to a fixed plate or a movable plate of a mold clamping device provided in a molding machine such as an injection molding machine from falling.
[0002]
[Problems to be solved by the invention]
The mounting of a mold in a molding machine having a normal structure is performed by bolting or clamping the mold to a mold mounting plate fixed to a fixed board or a movable board. In recent years, there is a type in which a mold mounting plate is formed of a magnet plate and a mold is magnetically attached. However, except for bolting, there is a risk that the mold may fall due to an accident with these mounting means.
[0003]
For example, in the case of clamps, most of them use hydraulic cylinders to tighten the clamps.However, the horizontal type clamping device has a machine base on the lower side, so the arrangement of the clamp device is limited to both sides. In addition, since there is no clamp device for supporting the lower side, when the pressure is reduced due to oil leakage of the hydraulic circuit and the tightening force is weakened, the mold may slip and drop due to its own weight.
In the case of using a magnet plate, the magnetic force generated by the excitation due to energization is attenuated, and if the magnetic adhesion becomes weaker than the weight of the mold, the mold falls.
[0004]
Therefore, in order to prevent dropping, mounting with bolts is the most preferable, but since bolting is a manual operation, it takes time and time to replace the mold as compared with clamping and magnetic attachment, and At present, mounting by hydraulically operated clamps is overwhelmingly unsuitable for automation.
[0005]
An object of the present invention is to solve the problem of mold drop when using the above-mentioned clamps, magnet plates, etc., and it is possible to use together with various kinds of mounting means, and to easily connect the mold mounting plate and the mold. Provided is a new mold drop prevention method for a molding machine that can surely prevent the fall of the mold even if the mold dimensions are different, and can easily perform the alignment between the mold center and the nozzle position. It is in.
[0006]
[Means for Solving the Problems]
The present invention according to the above object provides a die mounting plate for a fixed platen or a movable platen on a machine base and a contact surface of a die fixed to the die mounting plate by clamping or magnetically attaching to each other. Similarly, at the center in the plane from both side ends, at least a pair of left and right key grooves formed by recessing and forming the bottom part, and the hole formed by overlapping the key groove of the mold mounting plate and the key groove of the mold A key member which is inserted and fitted from the side end surface of the mold mounting plate to integrally connect the mold mounting plate and the mold; and a shaft member rotatably mounted adjacent to the key groove on the side end surface of the mold mounting plate. And a stopper which is always resiliently positioned at the open end of the key groove by a spring member. The length of the key member is made equal to the length of the key groove of the mold mounting plate. Insert and fit into the key groove from the end face, position the outer end face of the key member on the side end face of the mold mounting plate, and And received by the serial fasteners to prevent coming off of the key member, made to prevent falling of the mold, is that.
[0007]
Further, the present invention provides the method of preventing a mold from falling in a molding machine, wherein the key groove is formed from a side end face and a lower end face in the center of both sides and a lower side of both contact surfaces of the mold mounting plate and the mold. A key member that is recessed at the same position in the center of the plane and inserted into the key groove from the side end surface and the lower end surface of the mold mounting plate into the hole formed by overlapping the key groove, respectively. The outer end surface of the key member is rotatably mounted adjacent to the key groove on the side end surface and the lower end surface of the mold mounting plate, and is received by a stopper always located at the open end of the key groove, and the key member The escape is prevented, and the key groove and the key member enable the center of the mold to be set at the nozzle position regardless of the size of the mold.
[0008]
It is preferable that the keyway has a cross-sectional shape having an engagement surface for preventing the mold from falling forward by connecting the mold mounting plate and the mold. For example, the cross-sectional shape of the hole formed by the polymerization of both key grooves is a punch shape, a dumbbell shape, or the like, and the key member also has a long cross-sectional shape that matches those shapes.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
In FIG. 1, reference numeral 1 denotes a fixed plate installed on a machine base 2, which has a mold mounting plate 3 made of a ferromagnetic material such as steel on an inner surface facing the movable plate, although not shown in the figure. An exciting coil is provided inside the mold mounting plate 3 so that the mold 4 can be magnetically attached as a magnet plate by energization.
[0010]
A dovetail-shaped key groove 5 having an enlarged bottom is formed on the contact surface of the mold mounting plate 3 with the mold 4 from the center of the three sides of the both ends 3a, 3a and the lower end 3b. It is recessed to the center. A dovetail-shaped key groove 6 having an enlarged bottom is also formed on the contact surface of the mold 4 with the mold mounting plate 3 on both sides 4a, 4a and the lower and upper ends 4b, 4b. From the center to the in-plane center, the key groove 5 on the mold mounting plate side is recessed at the same position.
The key grooves 5, 6 of the lower ends 3b, 4b are formed by the key grooves 5, 6 of the both ends 3a, 4a and the key member 7 inserted and fitted therein so that the center of the die 4 is of the size of the die. Since it is set at the nozzle position regardless of the size, it is omitted in the figure, but may be similarly provided on the upper side. It goes without saying that the purpose of sufficiently preventing the mold 4 from falling can be achieved by using only one pair of both side ends 3a and 4a.
[0011]
The key member 7 has the same cross-sectional shape as the punch-shaped hole 8 (see FIG. 2) formed by the polymerization of the key grooves 5 and 6. The key member 7 has the same length as the key groove 5 of the mold mounting plate 3 and has a stopper 9 protruding from the outer end.
[0012]
Reference numeral 10 denotes a plate-shaped stopper, which is rotatably fastened to the side end surface 3a of the mold mounting plate 3 by a screw pin 11 so as to close the open end of the key groove 5. The spring member 12 is provided between the stopper 10 and the side end surface 3 a so as to be inserted around the screw pin 11 so that the spring member 12 resiliently presses the stopper 10 toward the contact surface. As a result, the stopper 10 is always located at the opening end of the key groove 5. Reference numeral 13 denotes a knob of the stopper 10.
[0013]
FIG. 4 shows an embodiment in which the mold 4 is mounted on the fixed platen 1 or the movable platen (not shown) by hydraulically actuated clamp devices 14 provided on both sides of the mold mounting plate 3. It is. As described above, even if the mold attaching means is different, the installation positions of the clamp devices 14 and 14 are located on the upper and lower sides, so that the key groove 5 uses the magnet plate as the mold attaching plate 3 as in the embodiment shown in FIG. It can be recessed at the center of both sides and the center of the lower side of the mold mounting plate 3, and the recessed position of the key groove 6 on the contact surface of the mold 4 does not need to be changed. The hole 8 into which the key member 7 is inserted can be formed by overlapping the key groove 5 on the contact surface of the mold mounting plate 3.
[0014]
Prevention of dropping of the mold 4 by the key grooves 5 and 6, the key member 7, and the stopper 10 is performed after positioning the carried-in mold 4 and the mold mounting plate 3. Since the key grooves 5 and 6 are overlapped with each other by this alignment to form the hole 8, the key member 7 is fitted into the hole 8 at the opening end of the key groove 5 on the side surface of the mold mounting plate 3. It can be done with a simple operation of inserting.
[0015]
As shown in the figure, keyways 5 and 6 are formed in the mold mounting plate 3 and the lower ends 3b and 4b of the mold 4, and the mold 4 is mounted on three sides by the left and right sides. In this case, the center of the mold 4 necessarily coincides with the nozzle position 20 at the center of the fixed platen by the key members 7 inserted therein.
[0016]
When the key member 7 is inserted, the open end of the key groove 5 is always closed by the stopper 10 pressed by the spring member 12. The key member 7 is inserted after being shifted to the side. Also, when the key member 7 is sufficiently pushed in so that the outer end surface thereof is flush with the side end surface 3a of the mold mounting plate 3, the stopper 10 which has been prevented from returning by the key member 7 is returned to the original state by the spring member 12. And hits the stopper 9 projecting from the outer end face, and serves as a cover crossing the lower side of the outer end face to prevent the key member 7 from coming off. For this reason, the key member 7 after being inserted is fitted into the key grooves 5 and 6 of both the mold mounting plate 3 and the mold 4 to be integrated as long as the stopper 10 is not manually turned to remove it from the outer end surface. Are combined.
[0017]
In the mold 4 coupled to the mold mounting plate 3 by the key grooves 5 and 6 and the key member 7, the magnetic force generated by the excitation by energization is attenuated, and the magnetic force is weaker than the weight of the mold. The mold 4 slips on the mold mounting plate 3 due to its own weight and falls due to the looseness of the fixing of the mold 4 due to the loss of the binding force of the mold 4 or the decrease in the clamping force due to the clamp. Even if a situation occurs, the key member 7 prevents the fall. The engagement surface formed by enlarging the bottoms of the key grooves 5 and 6 also prevents the mold 4 from falling forward from the mold mounting plate 3.
[0018]
When the mold is replaced, it is only necessary to turn the stopper 10 to the side and then pull out the key member 7, so that the handling is extremely simple. If the length of the key groove 5 of the mold mounting plate 3 is set to be long in advance together with the key member 7 in accordance with the minimum mold size, it can be applied as it is regardless of the size of the mold. Since the center of the mold can be set at the nozzle position regardless of the size of the mold, there is little trouble in the operation even for a molding machine that requires the exchange of molds of various specifications. Also has many advantages, such as being able to reliably prevent falling.
