Regarding the application device for applying powdered heat insulating material to the inner surface of the injection sleeve, in particular, the powdered heat insulating material is blown into the injection sleeve from the spout side of the injection sleeve, and the powdered heat insulating material is statically applied to the inner surface of the injection sleeve. This invention relates to an apparatus for applying powdered heat insulating material to the inner surface of an injection sleeve by electro-coating.

どの不具合があった。Therefore, when blowing and supplying powdered heat insulating material into the inside of the injection sleeve from the pouring port side of the injection sleeve, it is necessary to keep the injection sleeve with the injection port (opening on the mold side) open, that is, with the mold open. When powdered insulation is injected, the powdered insulation flows smoothly along the inside of the injection sleeve, making it easier to spread it throughout the inside of the injection sleeve.
On the other hand, much of the powdered heat insulating agent that was blown and supplied was discharged to the outside from the injection port of the injection sleeve, reducing the efficiency of using the powdery heat insulating agent and at the same time causing the powdery heat insulating agent to adhere to the inner surface of the casting hole pusher. There were problems such as the accumulation of particles causing poor mold matching, and the scattering around the casting equipment, worsening the working environment.

The powder heat insulating material can be applied with sufficient adhesion, and there is no risk that the powder heat insulating material will adhere to the inner surface of the casting spout pusher or be scattered around the casting device. The present invention aims to provide a coating device for a heat insulating agent.

る。<Effects of the Invention> The apparatus for applying powder heat insulating material to the inner surface of the injection sleeve according to the present invention is thus equipped with a closing plate for blocking the injection port of the injection sleeve, so that the inside of the injection sleeve can be accessed from the pouring port side. This eliminates the habit of the powdered heat insulating material being blown into the injection sleeve and being discharged to the outside from the injection port of the injection sleeve, which greatly improves the usage efficiency of the powdered heat insulating material. It is possible to prevent the occurrence of problems such as powdered heat insulating material accumulating and causing poor mold matching, or scattering around the casting equipment and worsening the working environment.

熱剤を行き渡らせ付着塗布することが出来る。Moreover, a hole communicating with the inside of the injection sleeve is formed in the closing plate, and a suction port for sucking out excess powder heat insulating material inside the injection sleeve to the outside of the injection sleeve is connected to the hole. Powdered insulation can be blown into the interior of the injection sleeve under the same conditions as when the injection port of the injection sleeve is opened, so that the powdered insulation can be spread smoothly and efficiently throughout the interior of the injection sleeve. At the same time, the powder heat insulating agent can be sufficiently spread and applied to the injection port of the injection sleeve.
更に、射出スリーブ内の余剰の粉状断熱剤は閉塞板の通
口を通して吸込み口で吸い出されてしまうので、吸い出

る。Further, since the excess powder heat insulating agent in the injection sleeve is sucked out by the suction port through the opening of the closing plate, the excess powder heat insulating agent sucked out can be recovered and reused.
又、射出スリーブの射出口は閉塞板で閉塞されているの
で、金型のキャビティに塗布する離型剤が射出スリーブ
内に混入する惧れもなくなる。Furthermore, since the injection port of the injection sleeve is closed by the closing plate, there is no possibility that the mold release agent applied to the cavity of the mold will get mixed into the injection sleeve.
よって、所期の目的を達成し得る。Therefore, the intended purpose can be achieved.
