Description
【発明の詳細な説明】 本発明は自硬性鋳型砂の定量吹込鋳型造型機に関する。[Detailed description of the invention] The present invention relates to a metering mold making machine for self-hardening molding sand.
従来、鋳型造型法としては：（１）熱可塑性又は熱硬化
性バインダーを被覆した砂を加熱した金型（コアーボッ
クス）に充填し、バインダーを硬化させて鋳型を造型す
る方法、（２）粘結剤を混入した砂を鋳枠内に充填し、
高圧プレス（スキーズ）させて鋳型を硬化させて造型す
る方法（生砂型法）、
（３）コアボックス内に充填したレジンサンドにある種
の触媒ガスを通気させ、化学反応により鋳型を硬化させ
て造型する方法
に大別される。Conventional mold making methods include: (1) filling sand coated with a thermoplastic or thermosetting binder into a heated mold (core box) and curing the binder to form a mold; Fill the casting flask with sand mixed with binder,
A method in which the mold is hardened using a high-pressure press (squeeze) to create the mold (green sand mold method); (3) A type of catalytic gas is passed through the resin sand filled in the core box, and the mold is hardened by a chemical reaction. It is broadly divided into molding methods.
しかるに最近は新規な種々のバインダーが開発され、砂
にこの種バインダーと触媒を混練して鋳枠又はコアーボ
ックス内に充填し放置すると、常温で自硬硬化する、所
謂自硬性プロセスが多く採用されるようになっている。Recently, however, various new binders have been developed, and a so-called self-hardening process, in which sand is kneaded with this type of binder and catalyst, filled in a flask or core box, and left to harden at room temperature, is often adopted. It has become so.
しかし乍ら、この方法は短時間で硬化するため、混練さ
れた造型材料は迅速に処理、即ち型込めしなければ造型
材料が自硬化する結果となり、硬化時間をコントロール
するため触媒の量を変えて使用可能時間を長くしたりし
ているが、この結果生産性が悪くなる傾向がある。However, since this method cures in a short time, the kneaded molding material must be processed quickly, that is, molded, otherwise the molding material will self-cure, and the amount of catalyst must be changed to control the curing time. However, as a result, productivity tends to deteriorate.
これらの欠点を改善するために、ある種のミキサーを用
いて、鋳型の容積に適合した量を混練し作業者が手込め
で充填する方法が多く行われているが、鋳枠外に飛散す
る造型材料が無駄になり、手込めのために生産性が悪い
。In order to improve these shortcomings, there are many methods in which workers use a mixer to mix the amount that matches the volume of the mold and then manually fill the mold, but this method often causes the mold to scatter outside the mold. Materials are wasted and productivity is poor due to manual labor.
この生産性を向上させるため通常の砂吹込機を使用する
と、ブローマガジン内に残った造型材料が自硬硬化して
、次の吹込み工程に悪影響を与えることになる。If a normal sand blowing machine is used to improve productivity, the molding material remaining in the blow magazine will self-harden, which will adversely affect the next blowing process.
前記の如き諸欠点をなくし、生産性を高めかつ造型材料
の浪費をさけるためには、−造型毎に鋳枠の容積に適合
するだけの砂量とバインダー量とを自動的に計測、混練
すればよく、本発明者はこの自動計測混練を可能とした
自硬性鋳型砂の定量吹込鋳型造型機の開発に成功したも
のである。In order to eliminate the above-mentioned drawbacks, increase productivity, and avoid wasting molding materials, it is necessary to automatically measure and knead the amount of sand and binder to match the volume of the flask for each molding. Fortunately, the present inventors have succeeded in developing a machine for making quantitative blowing molds for self-hardening molding sand that enables this automatic measurement and kneading.

吹込みで充填するものであるから、自硬性砂の迅速硬化
に適合し、生産性が高められる。The molding machine of the present invention has the above-mentioned configuration, and the functions and effects achieved by the present invention are listed as follows: (1) Flakes or cores with various mold weights (capacities) When making box molds, the amount of sand and binder that matches the desired mold is automatically measured each time, and the entire amount is filled in one blow, making it suitable for the rapid hardening of self-hardening sand and production. Sexuality is enhanced.
（２）バインダーは一般に粘度の高い液状物質が多く、
混練砂は湿潤状である。(2) Binders are generally liquid substances with high viscosity;
The mixed sand is in a wet state.
本発明造型機では吹込中でも羽根を回転しているので、
砂を撹散させる役目をし、充填効果を高めうる。In the molding machine of the present invention, the blades are rotated even during blowing, so
It plays the role of stirring up sand and can enhance the filling effect.
（３）湿潤状混練砂の自然落下角度は約６０°である。(3) The natural falling angle of wet kneaded sand is approximately 60°.
マガジン部内面の逆円錐部の頂角を６００以下としてい
るので、マガジン内に砂が残留、硬化せず、次回操作に
悪影響を与えず、清掃も不用となる。Since the apex angle of the inverted conical part on the inner surface of the magazine part is set to 600 or less, sand does not remain in the magazine and harden, and does not adversely affect the next operation, and cleaning is not necessary.

適であり、混線時間＋吹込時間を短時間にセットできる
。(5) Since the kneading operation is possible even while the blow magazine is moving, it is particularly suitable when using a binder with a short curing time, and the mixing time + blowing time can be set to a short time.
（６）ブローマガジン内の混練砂は１回の吹込工程で全
量排出されるので、排気時空気と砂を遮断するフィルタ
