明細書 型抜き補助装置 技術分野 ' 本発明は上下銪型同時造型の抜粋式錡型造型機において、 造型した上錶型から パターンプレートを離型するための型抜き補助装置に関する。 TECHNICAL FIELD The present invention relates to a die-cutting assist device for releasing a pattern plate from a molded upper die in an extractive-type die making machine of simultaneous upper and lower die making.
背景技術 Background art
鎵型造型機で錡型をスクィズ造型した後、 該錄型からパ夕一ンプレートを離型 する作業がある。 この作業においてパターンプレートを引き離す際に鎵型にパ夕 ーンプレートが一時的に吊り下がり、 その後落下した錶型が欠けてしまうことが あった。 この不具合を防ぐために錶枠又はパターンプレートにバイブレー夕一を 取り付け、 該バイブレータ一の発する振動を利用して铸型とパターンプレートを 離型する方法が従来より行われてきた。 After squeezing mold 錡 with mold 機, there is a work to release the mold plate from mold 錄. In this operation, when the pattern plate was pulled apart, the pattern plate was temporarily suspended in the shape of a triangle, and then the shape of the triangle was dropped. In order to prevent this problem, a method of attaching a vibrator to a frame or a pattern plate and separating the mold plate from the mold plate by using vibration generated by the vibrator has been conventionally performed.
また、スプリングにより稼働する型抜きピンを錡枠の各コーナ一に取り付けて、 離型時に型抜きビンがパターンプレートを抜き出すように構成した型抜き補助装 置も従来よりあった。 There has also been a conventional die-cutting assisting device in which a die-cutting pin operated by a spring is attached to each corner of a frame so that the die-cutting bin pulls out the pattern plate when releasing.
しかし、 バイブレ一夕一による型抜き補助は振動や騒音が激しく、 作業環境を 著しく低下させるものであった。 However, the assistance of die-cutting by vibrating all over the place caused a lot of vibration and noise, which significantly reduced the working environment.
また、 スプリング式の型抜きピンからなる型抜き補助装置は各コ一ナ一のスプ リングの圧力に差が生じ、 均等にパターンプレートを抜き出すことができなかつ た。 そのためパターンプレートが傾斜する等の不都合が起こり、 錡型に欠けが発 生する要因となっていた。 In addition, in the die-cutting assist device including a spring-type die-cutting pin, a difference occurs in the spring pressure of each corner, and the pattern plate cannot be drawn out evenly. As a result, inconveniences such as inclination of the pattern plate occurred, and this was a factor of causing chipping of the 錡 type.

発明の詳細な説明 Detailed description of the invention
以下本発明の実施の形態を図面に基づいて詳しく説明する。 図 1は本発明に よる型抜き補助装置の一部の構成を示す。 1はエアシリンダで、 上鎵枠 2の下フ ランジ部 2 Aの 4個所の各コーナー部に下向きにして固定されている。 該エアシ リンダ 1のビストン口ッド 1 Aは前記下フランジ部 2 Aの下面から点線で示す位 置まで突出可能であり、 それによりパターンプレートをその位置まで押し下げる ことができるようになる。 また、 エアシリンダ 1は下フランジ部 2 Aの各コーナ 一部以外の部分に配置することもでき、 エアシリンダの数もそれに応じて増減す ることができる。 本実施例に係る 4つのエアシリンダ 1に連結されたエア配管 1 0および 1 1は、 図 2に示すように、 エア配管 2 0および 2 1によって連通され ており、 それらのエア配管 2 0および 2 1は図示しない外部エア供給源に電磁弁 3及び減圧弁 4を介して連通連結している。 図 1および図 2は、 ビストンロッド 1 Aがエアシリンダ 1内に引っ込められるように電磁弁 3が切換えられている状 態を示す。 なお、 5は上錶型、 6はパターンプレート、 7は下錶枠である。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows the configuration of a part of a die-cutting assisting device according to the present invention. Reference numeral 1 denotes an air cylinder, which is fixed downward at each of the four corners of the upper flange 2 and the lower flange 2A. The piston hole 1A of the air cylinder 1 can protrude from the lower surface of the lower flange portion 2A to a position shown by a dotted line, whereby the pattern plate can be pushed down to that position. Further, the air cylinder 1 can be arranged at a portion other than a part of each corner of the lower flange portion 2A, and the number of the air cylinders can be increased or decreased accordingly. The air pipes 10 and 11 connected to the four air cylinders 1 according to the present embodiment are connected by air pipes 20 and 21 as shown in FIG. Reference numeral 21 is connected to an external air supply source (not shown) via a solenoid valve 3 and a pressure reducing valve 4. 1 and 2 show a state where the solenoid valve 3 is switched so that the piston rod 1A is retracted into the air cylinder 1. FIG. 5 is an upper frame, 6 is a pattern plate, and 7 is a lower frame.
上記のように構成した型抜き補助装置を使用して上錡型 5とパターンプレート 6を離型する工程を以下説明する。図 1において上錡枠 2、パターンプレ一ト 6、 下鎵枠 7が重ねられた状態で、 電磁弁 3を切り換えると、 減圧弁 4により調圧さ れたエアがエア配管 2 0および 1 0を経由して各エアシリンダ 1に供給され、 各 ビストンロヅド 1 Aが前進する。 各ビストンロヅド 1 A先端がパターンプレート
6を同圧力でもって均等に下方に押しつけながら上錡枠 2と共に上錡型 5が上昇 して、 錶型 5とパターンプレート 6を離型させ、 その結果、 それらは図 3に示す 状態となる。 The step of releasing the upper mold 5 and the pattern plate 6 using the above-configured die-cutting assisting device will be described below. In FIG. 1, when the solenoid valve 3 is switched in a state where the upper frame 2, the pattern plate 6, and the lower frame 7 are overlapped, the air regulated by the pressure reducing valve 4 causes the air piping 20 and 10 to flow. The air is supplied to each air cylinder 1 via, and each biston load 1A moves forward. Each biston load 1A tip is a pattern plate The upper mold 5 rises together with the upper frame 2 while uniformly pressing the same downward with the same pressure, and the mold 5 and the pattern plate 6 are released, resulting in the state shown in FIG. .
本発明による型抜き補助装置は上記の説明から明らかなように、 エアシリン ダを使用するので、 バイブレーターを使用したときのような振動や騒音は発生し ない。 また、 減圧弁によりエア圧を調節して複数のエアシリンダを同圧で駆動す るので、 スプリング式の型抜きビンとは異なり鎵型からパターンを均等に抜き出 すことが可能となる。 よって、 錡型に欠けが生じるといった不具合はなくなる。 本発明の一実施例においてはシリンダを駆動する手段としてエアを用いたが、 それに限定されるものではなく、 エア以外の例えばオイル等の流体を用いること ができる。
As is apparent from the above description, the die-cutting assisting device according to the present invention uses an air cylinder, and thus does not generate vibration or noise as when a vibrator is used. In addition, since a plurality of air cylinders are driven at the same pressure by adjusting the air pressure with a pressure reducing valve, it is possible to extract the pattern evenly from the 鎵 type unlike the spring type dies. Therefore, the problem of chipping of the に type is eliminated. In one embodiment of the present invention, air is used as a means for driving the cylinder. However, the present invention is not limited to this. A fluid other than air, such as oil, can be used.
