Description

本発明は小型で卓上用として使用出来る真空注型機に関する。   The present invention relates to a vacuum casting machine that is small and can be used for desktop use.

一般的な真空注型機はアームの先端にカップを取付けておき、それぞれのカップに液を入れた後、真空引きを始める。真空状態になった後、アーム操作によって混合し、撹拌してから型に流し込み、大気圧に戻して硬化させていた。又、このアーム操作の機構や駆動力及び、前記撹拌機構を備えなければならないため、装置が大型化し、真空ポンプや真空槽が大型になると、真空ポンプの排気速度が大きなものを使用しなければならず、電気の消費量が増えると共に装置全体の価格が高いものとなっていた。更にその装置を設置する場所も広く確保する必要があった。   A general vacuum casting machine attaches a cup to the tip of an arm, puts liquid into each cup, and starts evacuation. After being in a vacuum state, they were mixed by arm operation, stirred, poured into a mold, and returned to atmospheric pressure to be cured. In addition, since the arm operation mechanism and driving force and the agitation mechanism must be provided, if the apparatus becomes large and the vacuum pump or vacuum tank becomes large, a vacuum pump with a large exhaust speed must be used. In other words, as the consumption of electricity increased, the price of the entire device became high. Furthermore, it was necessary to secure a wide place for installing the apparatus.

尚、真空注型機の提案としては、特開2007−130863号,特開2007−136713号,特開平6−8261号などがある。特開2007−130863号の構造は、注入口を備えた型を収納可能な減圧室と、注型材容器と、硬化剤容器と、収納された注型材を撹拌し、脱泡と撹拌を行う撹拌装置と、硬化剤注入装置と、注型材注入装置と、それらの各装置を制御する制御装置とを備えたものであった。このため、前記各装置を駆動させるために、撹拌モータ,撹拌伝達機構,傾斜モータ,揺振動装置などが用いられているため、構造や作動及びその制御が複雑であり、高価な装置となり、小型化して卓上用とする発想はないものであった。また特開2007−136713号の構造は、特開2007−130863号の構造に、運動装置と増圧装置とを備えたものであるため、卓上用として使用出来るまで小型化することは困難であった。   In addition, as a proposal of a vacuum casting machine, there exist Unexamined-Japanese-Patent No. 2007-130863, Unexamined-Japanese-Patent No. 2007-136713, Unexamined-Japanese-Patent No. 6-8261, etc. JP-A-2007-130863 has a depressurization chamber capable of accommodating a mold equipped with an inlet, a casting material container, a curing agent container, and a stirring material for stirring and defoaming and stirring. An apparatus, a curing agent injection device, a casting material injection device, and a control device for controlling each of these devices were provided. For this reason, a stirring motor, a stirring transmission mechanism, a tilting motor, a vibration vibration device, and the like are used to drive each of the above devices, so that the structure and operation and control thereof are complicated, and the device becomes expensive and small. There was no idea to turn it into a tabletop. Further, since the structure of Japanese Patent Application Laid-Open No. 2007-136713 is provided with an exercise device and a pressure increasing device in addition to the structure of Japanese Patent Application Laid-Open No. 2007-130863, it is difficult to reduce the size until it can be used for a desktop. It was.

又、特開平6−8261号の構造は、真空槽内でカップホルダを回動させて、そのカップホルダに取付けられた注入カップ内の主剤又は硬化剤を、硬化剤又は主剤が入れられた撹拌カップ内に注入し、その主剤及び硬化剤を撹拌カップ内で撹拌して型内に注入して成型する真空注型機において、カップホルダが上方に延長され、その延長部に添加物カップが取付けられたものである。このため、注入カップ内の主剤又は硬化剤の撹拌カップ内に注入する際にカップホルダを回動させると、添加物カップも同時に回動され、添加物カップ内の添加物は撹拌カップ内に注入される。従って、従来品の構成を大幅に変えることなく、且つ、添加物が添加されるための新たな動作を設けなくても、注入カップを回動させる動作を利用して極めて簡易に添加物を添加することが出来るようにしたものであった。しかしながら特開平6−8261号は、注入カップを傾けて撹拌カップに注入する動作や撹拌羽根の動作及び撹拌カップを傾けてジョウゴに注入する動作が個別に必要であり、且つ、その個別の機構が必要であるため、特開平6−8261号の構造を簡略化して卓上用にすることは難しいものであった。   Further, the structure of Japanese Patent Laid-Open No. 6-8261 is such that a cup holder is rotated in a vacuum chamber, and a main agent or a hardener in an injection cup attached to the cup holder is stirred with a hardener or a main agent. In a vacuum casting machine that injects into the cup and stirs the main agent and curing agent in the stirring cup and injects them into the mold, the cup holder is extended upward, and the additive cup is attached to the extension It is what was done. For this reason, when the cup holder is rotated when injecting into the stirring cup of the main agent or curing agent in the injection cup, the additive cup is also rotated at the same time, and the additive in the additive cup is injected into the stirring cup. Is done. Therefore, the additive can be added very easily using the operation of rotating the injection cup without significantly changing the structure of the conventional product and providing a new operation for adding the additive. It was something that could be done. However, Japanese Patent Laid-Open No. 6-8261 requires an operation of inclining the injection cup and injecting it into the stirring cup, an operation of the stirring blade, and an operation of inclining the stirring cup and injecting it into the jugo. Since it is necessary, it is difficult to simplify the structure of Japanese Patent Laid-Open No. 6-8261 and use it for a desktop.

次に本発明の使用方法を図5、図2に基づいて説明する。先ず始めに成型用型(5)をクランプする。この時、シリコンの成型用型(5)のゲート位置が、セットする際に混合カップ(3)の投下位置に来るように型押え板(61)の穴(61a)を選択し、成型用型(5)の前後から型押え板(61)で挟むと共に、長尺なネジ棒(62)と取付ナット(63)及び六角ナット(64)などを用いて、成型用型(5)を締付けて固定する。また混合カップ(3)は成型用型(5)をクランプする前に固定させておく。この時、混合カップ保持プレート(31)に立設させた起立部(32a)に混合カップ(3)の鍔部を当接させると共に当て板(32b)を、鍔部が起立部(32a)と当て板(32b)の間で挟持されるように取付けて図示しないビスなどで固定する。この混合カップ(3)の開口は図2のように垂直方向にセットされるのである。また前記開口の注ぎ口(3a)は図2に示すように、逃げ穴(31a)へ注入可能な位置に配置されている。   Next, a method of using the present invention will be described with reference to FIGS. First, the mold (5) is clamped. At this time, the hole (61a) of the mold holding plate (61) is selected so that the gate position of the silicon mold (5) is at the dropping position of the mixing cup (3) when setting, and the mold Clamp the mold (5) using the long screw rod (62), mounting nut (63), hexagon nut (64), etc. Fix it. The mixing cup (3) is fixed before the molding die (5) is clamped. At this time, the eaves portion of the mixing cup (3) is brought into contact with the upright portion (32a) erected on the mixing cup holding plate (31), and the abutment plate (32b) is placed between the eave portion and the upright portion (32a). It is attached so as to be sandwiched between the contact plates (32b) and fixed with screws (not shown). The opening of the mixing cup (3) is set in the vertical direction as shown in FIG. Moreover, the spout (3a) of the said opening is arrange | positioned in the position which can be inject | poured into a relief hole (31a), as shown in FIG.

その後、混合カップ保持プレート(31)を左右の取付用レール(1a)の溝に挿入すれば、収納カップ(2)は真空槽(1)の内部の定位置にスライド固定してセットされる。この時、混合カップ保持プレート(31)は容易に引き抜くことが出来る。次にクランプされた成型用型(5)を真空槽(1)の内部に入れる。この時、型押え板(61)を、左右及び下側の凸条(1b)と、左右の取付用レール(1a)と、更に混合カップ保持プレート(31)の下面によってガイドされながら真空槽(1)の内部の所定位置にセットされる。尚、この時、混合カップ(3)の注ぎ口(3a)が成型用型(5)のゲート位置相当にセットされていることを再確認して、型セットを終了する。   Thereafter, when the mixing cup holding plate (31) is inserted into the grooves of the left and right mounting rails (1a), the storage cup (2) is slid and fixed at a fixed position inside the vacuum chamber (1). At this time, the mixing cup holding plate (31) can be easily pulled out. Next, the clamped mold (5) is placed inside the vacuum chamber (1). At this time, the mold retainer plate (61) is guided by the left and right ridges (1b), the left and right mounting rails (1a), and the lower surface of the mixing cup holding plate (31) while being guided by the vacuum chamber ( 1) is set at a predetermined position inside. At this time, it is reconfirmed that the spout (3a) of the mixing cup (3) is set to correspond to the gate position of the molding die (5), and the die setting is finished.

次に収納カップ(2)の一方側に主剤、例えばポリウレタン樹脂を、他方側に硬化剤を、計量秤やカップなどによって所定量を入れる。この時、収納量が決定した後は、収納カップ(2)の側面にマジックなどで目印を付け、2回目以降は計量せず、目印の量を入れれば良い。   Next, a predetermined amount is put with a measuring scale, a cup, or the like, with a main agent such as polyurethane resin on one side of the storage cup (2) and a curing agent on the other side. At this time, after the storage amount is determined, a mark or the like is attached to the side surface of the storage cup (2) with a magic or the like.

2液が入れられた収納カップ(2)が収納カップ保持プレート(21)に固定された状態のものを、混合カップ保持プレート(31)に於いて、図2の図中の2点鎖線に示す位置に係止させて固定する。この時、収納カップ(2)が収納カップ保持プレート(21)に固定される際は、ワンタッチで固定出来るようになっている。   A two-dot chain line in the drawing of FIG. 2 shows a state in which the storage cup (2) containing two liquids is fixed to the storage cup holding plate (21) in the mixing cup holding plate (31). Lock in place. At this time, when the storage cup (2) is fixed to the storage cup holding plate (21), it can be fixed with one touch.

次に真空引きを行う。この時には、先ず始めに真空槽(1)の扉(1c)を閉めてロック状態にさせておく。その後、排気バルブ(12)を開き、吸気バルブ(13)を閉じる。次に真空ポンプ(9)を作動させて真空槽(1)の空気を抜く。この時の真空度は、真空ゲージ(10)で確認し、大気圧から−0.1MPs(メガパスカル)程度まで減圧させる。−0.1MPs程度で1〜2分前後放置し、真空槽(1)の内部の水分及び樹脂液内の水分と泡を抜く。減圧中に於いて主剤と硬化剤の脱泡が行われた後は、真空槽(1)のロック状態(停止固定状態)を解除し、真空槽(1)を回動自在にしておく。   Next, vacuuming is performed. At this time, first, the door (1c) of the vacuum chamber (1) is closed and locked. Thereafter, the exhaust valve (12) is opened and the intake valve (13) is closed. Next, the vacuum pump (9) is operated to evacuate the vacuum tank (1). The degree of vacuum at this time is confirmed with a vacuum gauge (10), and the pressure is reduced from atmospheric pressure to about -0.1 MPs (megapascal). -Leave at about 0.1 MPs for about 1 to 2 minutes, and remove moisture and bubbles in the vacuum chamber (1) and resin solution. After defoaming of the main agent and the curing agent during decompression, the locked state (stopped fixed state) of the vacuum chamber (1) is released, and the vacuum chamber (1) is made rotatable.

前記ロック解除の方法を図4に基づいて詳細に説明する。先ず始めに停止部材(73)の操作レバー(73a)を右に回すと、それに連結した作動軸(73b)が回転されて、真空槽(1)下部の作動レバー(73c)が図中に示す矢印のように押されて作動すると、ストッパー棒(73d)が引かれて架台(8)側に設けた係止穴から図中の矢印のように移動して外れるので、真空槽(1)のロック状態が解除されて、真空槽(1)は回動可能となる。次に操作レバー(73a)を右に回わした状態で真空槽(1)を手動で90度回転させる。この90度回転により、2つの樹脂液は図5の(a)から(b)の状態になると、図中の矢印のように混合カップ(3)に注がれる。   The unlocking method will be described in detail with reference to FIG. First, when the operation lever (73a) of the stop member (73) is turned to the right, the operation shaft (73b) connected thereto is rotated, and the operation lever (73c) below the vacuum chamber (1) is shown in the figure. When pushed and actuated as shown by the arrow, the stopper rod (73d) is pulled and moved as shown by the arrow in the figure from the locking hole provided on the gantry (8) side. The locked state is released and the vacuum chamber (1) can be rotated. Next, the vacuum chamber (1) is manually rotated 90 degrees with the operation lever (73a) turned to the right. When the two resin liquids are brought into the states (a) to (b) in FIG. 5 by this 90-degree rotation, they are poured into the mixing cup (3) as indicated by arrows in the figure.

次に混合カップ(3)に入れられた2液を混合し、撹拌を行う方法について説明する。先ず真空槽(1)自体を操作レバー(73a)の操作によって回動させ、主剤と硬化剤が混合され且つ撹拌されるのである。この2液が混合・撹拌される工程を更に詳細に説明すると、先ず始めに真空槽(1)を左右(図中に於いては上下)に約40度ずつ所定回数揺動させる。この時、5〜10回程度図5(c)に示す1点鎖線から2点鎖線間を揺動させると良い。又、混合カップ(3)内の撹拌ベラ(41)は、錘(44)によって略垂直状態を保持する。一方、混合カップ(3)内の2液は、真空槽(1)の揺動に伴って移動すると共に撹拌ベラ(41)に当って撹拌されるのである。2液を混合すると硬化反応が開始し、2液の温度が上昇して、キシレンやナフサ等のガスを放出し始め、除々に沸騰状態に移動する。尚、この混合・撹拌した後の可使時間は約60秒前後である。この時の真空槽(1)の動作は、回転軸(71)がベアリングで支持されていると共に戸車(74)によっても真空槽(1)が滑らかに支持されるので、真空槽(1)は滑らかで且つスムーズに回転されるのである。その後、吸気バルブ(13)を若干開けて、−0.097MPs程度まで戻して混合液の沸騰を押える。   Next, the method of mixing and stirring the 2 liquids put into the mixing cup (3) is demonstrated. First, the vacuum chamber (1) itself is rotated by the operation of the operation lever (73a), and the main agent and the curing agent are mixed and stirred. The process of mixing and stirring the two liquids will be described in more detail. First, the vacuum chamber (1) is swung a predetermined number of times by about 40 degrees left and right (up and down in the drawing). At this time, it is preferable to swing between the two-dot chain line from the one-dot chain line shown in FIG. The stirring spatula (41) in the mixing cup (3) is maintained in a substantially vertical state by the weight (44). On the other hand, the two liquids in the mixing cup (3) move as the vacuum chamber (1) swings and are agitated against the stirring spatula (41). When the two liquids are mixed, the curing reaction starts, the temperature of the two liquids rises, gas such as xylene and naphtha starts to be released, and gradually moves to the boiling state. The pot life after mixing and stirring is about 60 seconds. The operation of the vacuum chamber (1) at this time is that the rotary shaft (71) is supported by the bearing and the vacuum chamber (1) is also smoothly supported by the door wheel (74). It rotates smoothly and smoothly. Thereafter, the intake valve (13) is slightly opened and returned to about -0.097MPs to suppress the boiling of the mixed solution.

混合液の沸騰が若干おさまったら、真空槽(1)を左に90度回転させ、図5(d)に示す元の位置に戻すと、成型用型(5)に混合・撹拌された液が注ぎ込まれるのである。この時、真空槽(1)を元の位置に戻した後、操作レバー(73a)を手から離すと、スプリング(73e)によって、ストッパー棒(73d)は前記係止穴に差し込まれる。このストッパー棒(73d)が係止穴に挿入されると、真空槽(1)は略固定状態になる。一方、混合カップ(3)の混合液はその注ぎ口(3a)から図5(d)に示す矢印のように成型用型(5)のゲートに注がれる。そして成型用型(5)内にそれが充填される。   When the boiling of the mixed solution is slightly reduced, the vacuum chamber (1) is rotated 90 degrees counterclockwise and returned to the original position shown in FIG. 5 (d), and the mixed and stirred liquid in the molding die (5) is obtained. It is poured. At this time, after the vacuum chamber (1) is returned to its original position, when the operation lever (73a) is released from the hand, the stopper rod (73d) is inserted into the locking hole by the spring (73e). When this stopper rod (73d) is inserted into the locking hole, the vacuum chamber (1) is substantially fixed. On the other hand, the liquid mixture in the mixing cup (3) is poured from the spout (3a) into the gate of the molding die (5) as shown by the arrow in FIG. 5 (d). And it fills in the mold (5).

そして、吸気バルブ(13)を開け、大気圧に戻し、真空ポンプ(9)のスイッチを切って停止させる。停止後、真空槽(1)の扉(1c)を開けて、クランプされた成型用型(5)を取出す。そして、混合液の硬化を確認してから成型用型(5)を分割し、中の硬化した製品を取出す。この時には、先ずクランプ手段(6)の取付ナット(63)を弛めて、ネジ棒(62)から前側の型押え板(61)を外し、成型用型(5)を分解し、その内部で硬化した製品を取出せば、成型は終了するのである。   Then, the intake valve (13) is opened to return to atmospheric pressure, and the vacuum pump (9) is turned off to stop. After the stop, the door (1c) of the vacuum chamber (1) is opened and the clamped mold (5) is taken out. And after confirming hardening of a liquid mixture, a type | mold for mold (5) is divided | segmented and the hardened product in it is taken out. At this time, firstly, the mounting nut (63) of the clamping means (6) is loosened, the front pressing plate (61) is removed from the screw rod (62), the molding die (5) is disassembled, and the inside Once the cured product is removed, molding is complete.

このように本発明は、真空槽(1)内に於いて、収納カップ(2)自体や混合カップ(3)自体は回転や揺動を行わずに真空槽(1)内に固定されたままであり、真空層(1)自体を回転させて元の位置に戻せば、シリコン樹脂の成型用型(5)に注ぎ込むことが出来るため、従来に必要であった回転や揺動が行われるための各装置や機能が不要となり、真空槽(1)を小型化出来るものとなる。また装置全体の大きさは従来のものよりも小型化されて、卓上で使用可能なものとなるのである。   Thus, in the present invention, in the vacuum chamber (1), the storage cup (2) itself and the mixing cup (3) itself remain fixed in the vacuum chamber (1) without rotating or swinging. Yes, if the vacuum layer (1) itself is rotated and returned to its original position, it can be poured into the silicon resin molding die (5), so that the rotation and swinging required in the past are performed. Each device and function are unnecessary, and the vacuum chamber (1) can be miniaturized. In addition, the overall size of the device is smaller than that of the conventional device and can be used on a table.
