Abstract

PURPOSE:To improve the adhesiveness of a split mold surface and to take out plastic products easily by preparing a push pin for taking out a formed product from a lower mold and causing the moving locus of a lower mold-movable core to be the combination of a straight line and a circular arc. CONSTITUTION:After a plastic product has been formed, a gap 13 is opened by lifting a lever 16 and rotating an upper mold 11 centering a shaft 15. Next, when a lever 20 is lifted and rotated centering a shaft 19, a lever 21 is rotated simultaneously, and the guide pin 24 connected to the end part of the lever 21 is moved in axial direction upwardly. Therefore, a push out-plate 25 and a push pin 23 are also moved upwardly. Simultaneously, the lower mold movable core 12a fixed to the link 29 arranged on the plate 25 is moved upwardly at the beginning with the displacement of pin 30 engaged into the groove 26a of a cum plate 26 along the groove 26a. Consequently, the formed product is separated from the lower mold movable core 12a and is pushed out and separated from the lower mold-stational core 12b by the pin 23. Thus the product is easily taken out.
