【発明の詳細な説明】
本発明はプラスチック成形用金型又は成形機の冷却水回
路の洗浄法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for cleaning a cooling water circuit of a plastic mold or a molding machine.
一般にプラスチック成形においては、成形能力を向上さ

水を循環させるために多数の金型冷却筒からなる冷却水
回路が設計されているものである。同様にプラスチック
成形機においても上記のような理由から冷却水回路が形
成されているものである。Generally, in plastic molding, a cooling water circuit consisting of a large number of mold cooling tubes is designed to circulate cold water of about 5 to 20°C through the molding mold in order to improve molding performance. It is. Similarly, cooling water circuits are also formed in plastic molding machines for the reasons mentioned above.

な冷却効果を得ることができず、冷却時間が長くかかり
、ショツト数が落ちる等の重大な問題点が発生した。However, this cooling water circuit is constantly exposed to the formation of rust because the water cannot be completely discharged, and the rust adheres to the circuit along with scale, narrowing the pipes and blocking the flow of water, resulting in an extremely low flow rate. In addition, if rust or scale adheres to the cooling water circuit of the mold, it may not be possible to obtain the necessary cooling effect, resulting in serious problems such as long cooling times and a drop in the number of shots. A problem occurred.

となります。In particular, the most problematic substances in the cooling water circuit are calcium, magnesium salts, and silicon oxides, which are generally referred to as calcium-based scale and silica-based scale, and the main one is calcium hydrogen carbonate. , calcium sulfate, calcium chloride, magnesium bicarbonate, silica, etc. As these impurities circulate within the circuit, they become crystals and adhere to the inner walls of the circuit. Moreover, this scale is a hard substance that firmly adheres to the mold and forms a hole, so it cannot be easily removed, and the cooling effect of the mold will be significantly deteriorated.

を完全に遮断する事態となる。Furthermore, since a uniform temperature cannot be maintained, there are disadvantages in that the product tends to be distorted and dimensional, uneven wall thickness of the molded product, residual distortion, etc. are likely to occur. In particular, even a small amount of scale acts as a heat insulator, which has the disadvantage of significantly impairing the cooling capacity of the circuit. Furthermore, if the accumulation of rust and scale becomes severe, the cooling water circuit may be completely shut off. A situation arises.
