and the upper tool 22 is lifted away from the lower tool 20 to unclamp the tools 20 22 operation t 4 as the cam 26 retracts the biasing force of the spring 37 returns the follower block 35 to its original position which is shown in fig6 this permits the intermediate plate 38 and the die 34 to move downward along the walls of the slot 34 the air cylinder e below the support plate 29 is then driven to retract the cylinder rod 31 with the assistance of the biasing force of the spring 49 this lowers the intermediate plate 38 and the die 39 and returns the support block 41 to a position contacting the upper surface of the support plate 29 operation t 5 the cut off molded products p are held in the indentations 45 of the die 39 as the die 39 moves downward as shown in fig6 this creates a gap z between the molded products p and the material s and permits the material s to move without interference with the lower tool 20 afterward the cylinder 24 is driven to move the lower tool 20 along the base 4 toward the left as viewed in fig3 to location m operation t 6 this enables retrieval of the molded products p a robot arm.
