進入させるようにしたものである。The release agent injection nozzle 5 is configured and arranged so as to be able to advance and retreat into the injection sleeve 2 from the hot water supply port 4 of the injection sleeve 2. Although various configurations are conceivable for allowing the release agent injection nozzle 5 to advance and retreat into the injection sleeve 2, in the illustrated embodiment, the drive cylinder 6 is provided from above to the hot water supply port 4 of the injection sleeve 2. The release agent injection nozzle 5 is attached to the end of the rod 6a of the drive cylinder 6 through the manifold 7 at the tip of the rod 6a of the drive cylinder 6, and the release agent injection is performed by the forward / backward movement of the rod 6a of the drive cylinder 6. The nozzle 5 is adapted to enter the injection sleeve 2 through the hot water supply port 4 so as to be able to move back and forth.

かれ、再び給湯口４の上方に待機させる。When the mold release agent is applied to the cavity surfaces N 1 and N 2 of the mold 1 , first, the mold release agent injection nozzle 5 is connected to the injection sleeve 2.
Stand by above the hot water supply port 4. Next, at the same time when the mold 1 is opened and the plunger tip 8 finishes the backward movement, the drive cylinder 6 is operated to cause the release agent injection nozzle 5 to enter the injection sleeve 2 from the hot water supply port 4. Then, after the mold closing operation of the mold 1 is started and immediately before the end of the mold closing operation or immediately after the mold closing, the release agent is injected from the release agent injection nozzle 5 into the ejection sleeve 2. Then, this mold release agent is sent into the cavity N of the mold 1 through the injection sleeve 2 and applied to the cavity surfaces N 1 and N 2 and the surface of the core (cez in the figure) protruding into the cavity N. Then, the release agent injection nozzle 5 that has finished the injection of the release agent is pulled out from the hot water supply port 4 of the injection sleeve 2 by the drive cylinder 6 and is made to wait above the hot water supply port 4 again.

とがない。<Effects of the Invention> The present invention thus releases the mold release agent injection nozzle that has entered the injection sleeve after the mold closing operation of the mold and immediately before the end of the mold closing operation or immediately after the mold closing. Since the mold release agent is sprayed to apply the mold release agent to the cavity surface or core surface of the mold, unlike the conventional case, the mold release agent does not scatter outside the mold cavity. Therefore, the release agent is not wasted and the surrounding environment is not contaminated with the release agent.
しかも、離型剤をキャビティ面やキャビティ内に突出し
た中子の裏面にも行き渡らせることが可能となるので、
必要量の離型剤を金型のキャビティ面や中子表面に効果
的に塗布することが出来る。Moreover, since it is possible to spread the release agent to the cavity surface and the back surface of the core protruding into the cavity,
The required amount of release agent can be effectively applied to the cavity surface and core surface of the mold.
更に、機構構成が極めて簡単なもので済むために、設備
が安価に済む。Furthermore, the equipment can be inexpensive because the mechanical structure is extremely simple.
