防止する。 Next, the operation of the present invention will be explained. First, if the state shown in FIG. 1 is initially established during normal molding operation, when the handle 26 is lifted, the shaft A25 will rise along the guide groove 24, and the purge receiver (upper) 21 will move along the shaft B20. While rotating around the center,
Purge receivers (top) (bottom) 21 and 23 are hinge 22
It rises together with the axis A25 in a bent state. When the shaft A25 rises to the upper limit of the guide groove 24, when the handle 26 is pulled to the right and the nozzle cover 19 is retreated, the roller B of the shaft A25 moves as shown in FIG.
50 rides on the upper rail 15. (Note that this position is called the retraction limit position of the nozzle cover 19, and the nozzle cover 19 stops in contact with the stopper 42 at this position.) If the heating cylinder 11 is moved forward (to the left in the figure) at this point, the heating cylinder 11 The nozzle 13 attached to the tip of the nozzle 13 enters the nozzle touch hole 33 of the fixed die plate 32, and then the nozzle 31 touches the fixed mold 34. At this point, normal molding operation becomes possible. In this state, the nozzle cover 19 is in contact with the fixed die plate 32, thereby preventing the molten resin from scattering from the nozzle 31.

で生産性の向上する利点を有する。 Therefore, in the nozzle cover device of the present invention, the purge receiver is movably provided on the nozzle cover, and during the purge operation, the purge receiver hangs down in front of the nozzle to receive the purge resin, and during the molding operation, the purge receiver is folded and heated. Molding was made possible by placing it above the cylinder. This eliminates the need for attaching the purge receiver to the nozzle cover during the purge operation and removing the purge receiver during the molding operation, unlike in the conventional method, which has the advantage of improving productivity.
