CLAMPING DEVICE AND METHOD FOR CLAMPING RESIN-MOLDED SHEET

PROBLEM TO BE SOLVED: To solve the problem that an operator needs much power, when he inserts a finger into a gap between the upper face of a clamping frame and the lower face of a peripheral edge part of moldings and therefore, the operating efficiency is low. SOLUTION: When a specified number of p...

Zusammenfassung:	PROBLEM TO BE SOLVED: To solve the problem that an operator needs much power, when he inserts a finger into a gap between the upper face of a clamping frame and the lower face of a peripheral edge part of moldings and therefore, the operating efficiency is low. SOLUTION: When a specified number of projecting pins 20 are arranged on a clamping frame 13a of a clamping mechanism 13 and a cylinder device 30 corresponding to the projecting pin 20 is arranged on the side 12b of a molding die and further, the peripheral edge part of a resin-molded sheet S is separated from the upper face of the clamping frame 13a, the pin upper end part 21 of the projecting pin 20 is projected from the upper face of the clamping frame 13a by driving a cylinder shaft 32 of the cylinder device 30. Consequently, it is possible to separate the peripheral edge part of the resin-molded sheets from the upper face of the clamping frame 13a. Thus the operator need not resort to a manual work when the operator removes the resin-molded sheet S from the clamping mechanism 13.
