Claims

[Scope of utility model registration request]

A first mold having a mold 3 and an ejector sleeve 7 which is disposed so as to be able to come into contact with and separate from the mold 3 and which can penetrate the mold 3 and protrude above the upper surface of the mold 3. a second ejector plate 6 which is disposed so as to be able to come into contact with and be separated from the first ejector plate 5 and has a core 8 that is slidable within the ejector sleeve 7; a fixing member 15 that normally fixes the first ejector plate 5 and the second ejector plate 6 together, and that is separable when a predetermined force or more is applied;
a protruding rod 13 that penetrates the second ejector plate 6 and abuts the first ejector plate 5 and is capable of pushing up the first ejector plate 5; The first ejector plate 5 and the second ejector plate 6 are moved by the operation of the protruding rod 13. The ejector sleeve 7 and the core 8 are pushed up integrally from the upper surface of the mold 3, and the movement of the second ejector plate 6 is stopped by the limiting members 9 and 10. After that, the first ejector plate 5 is further pushed up against the fixing force of the fixing member 15, whereby only the ejector sleeve 7 located on the outer periphery of the core 8 is pushed upward. Molded product ejection device.
