本発明は鋳造中子の塗型方法及び装置に関す
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a casting core mold coating method and apparatus.
鋳造工程時、鋳型(主型、中子)に溶湯を注ぐ
と、湯温が高い程、又、鋳物、砂の耐火度が低い
程鋳型表面が荒される。そこで鋳肌を良くすると
共に、砂離れを良くして焼着を防止するため鋳型
表面の塗型剤(ジルコン砂、けい石粉末、黒鉛粉
等の耐熱性塗型剤)の水溶液(以下塗型液とい
う)を塗布することが行なわれる。 During the casting process, when molten metal is poured into a mold (main mold, core), the higher the temperature of the molten metal and the lower the refractory properties of the casting and sand, the rougher the surface of the mold becomes. Therefore, in order to improve the casting surface and improve sand removal to prevent burning, an aqueous solution of a coating agent (heat-resistant coating agent such as zircon sand, silica powder, graphite powder, etc.) on the mold surface (hereinafter referred to as coating material) The process involves applying a liquid (referred to as a liquid).
従来の塗型方法は、塗型液を圧力容器の中で撹
拌しながらエア圧力で塗型液を送り出し、スプレ
ーガンのノズルを通して噴霧状にして鋳型表面に
塗布するといういわゆるスプレー塗布方式であ
る。 The conventional mold coating method is a so-called spray coating method, in which the mold coating solution is stirred in a pressure vessel and sent out using air pressure, and is applied to the mold surface in the form of a spray through the nozzle of a spray gun.
しかしながら、かかる従来方法では、特に外表
面を塗布する中子の場合、次のような様々の問題
点を生じていた。 However, in this conventional method, the following various problems have arisen, particularly in the case of a core whose outer surface is coated.
(1) 塗型液が噴霧状になるため作業者周辺に飛び
散り作業環境が悪い。(1) The mold coating liquid becomes atomized and scatters around the worker, creating a poor working environment.
(2) 塗型液の7割近くが中子表面に付着しない
で、集塵機に吸収されたり大気中に放出されて
しまうため、経済的な損失も大きい。(2) Since nearly 70% of the mold coating liquid does not adhere to the core surface and is absorbed by the dust collector or released into the atmosphere, there is also a large economic loss.
(3) 中子表面に凹凸が多く複雑な形状である場合
はスプレーの死角が生じるため塗型液が付着さ
れにくく、鋳込後の焼着の原因となる。(3) If the core surface has many irregularities and a complex shape, a blind spot will occur for the spray, making it difficult for the coating liquid to adhere to the core, which may cause burning after casting.
(4) 塗型のムラを生じ、局部的に多くの塗型液が
付着するため、その部分の塗型液がたれて乾燥
するとダマ(球状の固形物)を生じて、後工程
での仕上げが必要となる。(4) This causes unevenness in the coating and a large amount of coating solution adheres locally, which causes lumps (spherical solids) to form when the coating solution drips in those areas and dries, which makes it difficult to finish in the subsequent process. Is required.
本発明は、これら従来の問題点に鑑みこれを解
消するため為されたもので、ドブ漬けを利用した

アーム3を実線位置と、これから180゜回転させた
鎖線位置とに切換えできるようにしている。 One end of the arm rotation shaft 4 is connected to the drive shaft of an arm rotation motor 17 via a gear train 16, and by rotating the motor 17 in forward and reverse directions, the arm 3 is rotated 180 degrees from the solid line position. It is possible to switch to the position indicated by the chain line.

ブ漬槽20内に戻されるので無駄がない。 In addition, in order to prevent the coating liquid from scattering when the core 21 is rotated and the excess coating liquid is shaken off by centrifugal force, as will be described later, when the core 21 is suspended vertically downward in the chain line position shown in the figure. A drum-shaped coating liquid scattering prevention cover 22 is provided to cover the periphery of the core while avoiding interference at the position of the dashed line in the soaking tank 20. The mold coating liquid scattering prevention cover 22 may be attached by fixing the lower end to the floor surface 18, the support stand 1, or the base 2, or by fixing the upper end to the arm 3 so that it can be attached and detached freely, but if there is enough space in the vertical direction. If there is (more room can be provided by lowering the hanging position from the arm 3), it may be fixed to the upper end of the gutter soaking tank 20 or formed integrally with the gutter soaking tank 20, in which case it may be separated. The excess mold coating liquid adheres to the inner wall of the cover 22 to prevent it from scattering to the surroundings, and then flows down and returns to the inside of the soaking tank 20, so there is no waste.
次に、かかる塗型装置を用いた塗型方法を説明
する。 Next, a mold coating method using such a mold coating device will be explained.

へ搬送する。 For example, in the case of cores for casting engine cylinder blocks, crank cores, end cores, and center cores fired in a shell machine are assembled on a wooden surface plate, pasted together with adhesive, and then glued. To fix it, it is strung with a rubber band, and after about 30 minutes, it is placed on the conveyor 8A and conveyed toward the table 7.

を防止できる。 After the setting, the soaking tank 20 located at the solid line position is raised by driving the lifter 19, and the clamper 1 is moved up.
The core 21 suspended and held by 2A and 12B is immersed in the mold coating liquid in the dipping tank 20. At this time, the mold coating liquid in the drip soaking tank 20 is held at liquid level A by the overflow mechanism, so that the core 21 can be molded only at a predetermined portion excluding the upper end in this state, and the inside of the core 21 can be coated. Since the mold liquid does not penetrate, wasteful consumption of mold coating liquid can be prevented.
次いで、前記モータ17を反転させてリフタ1
9と共にドブ漬槽20を下降させ、塗型液の付着
した中子21を数秒間空気中にさらした後、再度
ドブ漬槽20を上昇させて中子21を浸漬させ
る。 Next, the motor 17 is reversed and the lifter 1
After lowering the dipping tank 20 together with 9 and exposing the core 21 to which the mold coating liquid has adhered to the air for several seconds, the dipping tank 20 is raised again to immerse the core 21.
続いて、ドブ漬槽20を下降させ中子21を空

る。 Next, with the soaking tank 20 lowered and the core 21 exposed to the air, the table rotation motor 5 is driven to rotate the core 21 together with the table 7, and the centrifugal force generated at this time The excess coating liquid adhering to the surface of the core 21 is shaken off and separated.
The separated surplus coating liquid adheres to the inner wall of the coating liquid scattering prevention cover 22 and can be prevented from scattering to the surroundings.
こうして、塗型作業を終えると、モータ17を

に搬送させればよい。 When the mold coating work is finished, the motor 17 is reversed to rotate the arm 3 back to the conveyor 8A, 8B side, and then the pair of clampers 12A, 12
After rotating the core 21 back to the horizontal position and releasing the grip on the core 21, the core 21 is transferred to the conveyor 8B on the opposite side.
All you have to do is have it transported.
