Description
本発明は、Ｖプロ注湯枠の冷却に関するものである。 The present invention relates to cooling of a V-pro pouring frame.
従来、Ｖプロ注湯枠を冷却する装置は無かった。注湯時以降も真空吸引することにより、枠の昇温は抑制されている。 Conventionally, there has been no device for cooling the V-pro pouring frame. The temperature rise of the frame is suppressed by vacuum suction after pouring.
しかし、その真空吸引はある一定時間で止め、解枠まで、自然枠内冷却する工程があり、この時に、カウンタウエイト等、熱容量が大きい製品を鋳込む場合、鋳込品からの熱により、金枠や定盤の温度が上昇し、使用しているフィルムが、金枠や定盤へ溶着してしまう不具合が発生する事が有った。
本発明は、Ｖプロの注湯枠の昇温を抑え、フィルムの溶着を防止することを目的とする。 An object of this invention is to suppress the temperature rise of the pouring frame of V pro and to prevent film welding.
上記の課題を達成するために本発明における注湯枠冷却装置は、Ｖプロの注湯枠に対し、側面と下面へ圧縮エアーを吹き付け、冷却するようにしたことを特徴とする。 In order to achieve the above object, a pouring frame cooling device according to the present invention is characterized in that compressed air is blown onto the side surface and the lower surface of a pouring frame of a V professional to cool it.
金枠とフィルムが接する面を一辺とするチャンバーへ圧縮空気を吹き込み空冷することによって金枠の昇温を抑え、フィルムの溶着を防止することができる。
また、定盤の底面へ圧縮エアを吹きかけ、空冷することによって定盤の昇温を抑え、フィルムの溶着を防止することができる。
By blowing compressed air into a chamber whose side is in contact with the metal frame and the film and cooling it by air, it is possible to suppress the temperature rise of the metal frame and to prevent the film from being welded.
Further, by blowing compressed air to the bottom surface of the surface plate and air cooling, it is possible to suppress the temperature rise of the surface plate and prevent the film from being welded.
本発明を適用した注湯枠冷却装置について図面に基づき詳細に説明する。図3に示す様に、従来のVプロ用金枠は、鋳型を維持するために、上枠下枠共、側壁はチャンバー(中空)形状11であり、図示しない真空ポンプから吸引する事によりチャンバー11内部を真空とし、負圧により砂型10を形成している。砂型10は、上枠3、下枠4、上面フィルム7、製品面フィルム8、８、下面フィルム9によって囲まれ、吸引をかけられることにより、負圧にされ形状を保持している。 A pouring frame cooling device to which the present invention is applied will be described in detail with reference to the drawings. As shown in FIG. 3, the conventional V pro metal frame has a chamber (hollow) shape 11 on both the upper and lower frames to maintain the mold, and the chamber is formed by suction from a vacuum pump (not shown). 11 The inside is evacuated and the sand mold 10 is formed by negative pressure. The sand mold 10 is surrounded by the upper frame 3, the lower frame 4, the upper surface film 7, the product surface films 8 and 8, and the lower surface film 9, and is sucked to maintain a shape.
注湯時、製品面フィルム8、8のうち、鋳込製品6と接する部分は焼失するが、上枠3と下枠4にはさまれる部分はフィルム状のままであり、解枠時に除去される。又、上面フィルム7、下面フィルム9はフィルム状のまま解枠前に除去される。 During pouring, the part of the product surface film 8, 8 that comes into contact with the cast product 6 is burned away, but the part sandwiched between the upper frame 3 and the lower frame 4 remains in the form of a film and is removed when the frame is released. The Further, the upper film 7 and the lower film 9 are removed in the form of a film before unpacking.
注湯後、鋳込製品6がある程度冷え固まれば真空吸引を止め、枠内にて自然冷却させるが、この時に、カウンタウエイト等、熱容量が大きい製品を鋳込む場合、鋳込製品6の熱が砂型10を介して、上枠3、下枠4、定盤5に伝わり、前述の製品面フィルム8のうち、上枠3と下枠4にはさまれる部分と、下面フィルム9が金枠や定盤へ溶着してしまう不具合が発生する場合があった(図3)。
そこで、金枠の側面用ノズル1、1と定盤底面用ノズル2を設置し、圧縮エアーを吹き、冷却することとした。
After pouring, when the cast product 6 cools and hardens to some extent, the vacuum suction is stopped and the product is naturally cooled in the frame. At this time, when casting a product with a large heat capacity such as a counterweight, the heat of the cast product 6 It is transmitted to the upper frame 3, the lower frame 4, and the surface plate 5 through the sand mold 10, and the portion of the product surface film 8 that is sandwiched between the upper frame 3 and the lower frame 4 and the lower surface film 9 is a metal frame or There was a case where a problem of welding to the surface plate occurred (Fig. 3).
Therefore, the nozzles 1 and 1 for the side of the metal frame and the nozzle 2 for the bottom of the surface plate are installed, and compressed air is blown and cooled.
側面からのエアブローについては、見切面(上枠と下枠が合わさる面)側に空冷用チャンバー12、12を設け、着脱可能な側面用ノズル1、1を差し込み、手動バルブ14にてブローのオン・オフを操作する構造とした(図1,2)。
底面のエアブローについては、定盤5の下方中央付近へ底面用ノズル２を設置し、手動バルブ１３にてブローのオン・オフを操作する構造とした(図1,2)。
空冷用チャンバー12、12にはいくつかの穴が設けてあり、側面用ノズル1の差し込み口兼、空気の出入口となっている(図1)。
For air blow from the side, air cooling chambers 12 and 12 are provided on the parting surface (surface where the upper and lower frames are combined), the removable side nozzles 1 and 1 are inserted, and blow is turned on with the manual valve 14. -A structure that operates the switch off (Figs. 1 and 2).
Regarding the air blow on the bottom surface, the bottom nozzle 2 is installed near the lower center of the surface plate 5 and the blow valve is turned on and off with the manual valve 13 (FIGS. 1 and 2).
The air cooling chambers 12 and 12 are provided with several holes, which serve as insertion ports for the side nozzles 1 and air inlets and outlets (FIG. 1).
(工程)
金枠は造型から注湯後ある一定時間まで真空吸引がかけられる(砂型保持の為)。その後、吸引は止められ、枠内にて自然冷却されるが、この時、圧縮エアーを吹きかけ、積極的に空冷する。
(Process)
The metal frame is vacuumed for a certain period of time after casting (to maintain the sand mold). After that, the suction is stopped and naturally cooled in the frame. At this time, compressed air is blown to actively cool the air.
今回の発明は、半自動化設備のため、手作業によるノズルの着脱、手動バルブの構成としたが、エアシリンダ等のアクチエータを用い、ノズル着脱の自動化、電磁弁によるエアブローの自動化を行う事も可能である。 This invention is a semi-automated facility, so it is configured to manually attach and detach nozzles and manual valves. However, using an actuator such as an air cylinder, it is possible to automate nozzle attachment and detachment, and to automate air blow using solenoid valves. It is.
