Abstract

PURPOSE: To facilitate the centering and to easily respond to the need of many kind small quantity production by providing a vertically moving guide body of upper die and a vertically freely movable ring plate for lower die to confronting main pillars in order to surely and smoothly move the upper die and the ring plate vertically.
CONSTITUTION: When the upper die 24 is moved down to the lower die 6, the guide body 26 of the upper die 24 is relatively moved down along the main pillars 3, and the upper die 24 is stably lowered vertically to the lower die 6 without the failure of centering. When the guide body 26 is moved down, the hanging rods 62 provided to both sides of the guide body 26 is lowered by the returning force of both coil springs 48 of compressed state, and the ring plate 43 hung with the hanging rods 62 is pushed down and vertically lowered. When the ring plate 43 is lowered to the specified position, the lower ring 50 of the ring plate 43 is fitted on the lower die 6, and the upper die 24 is moved down without receiving the repulsing force of the coil springs 48 and inserted into the sliding opening of the ring plate 50 to press the molten glass in the lower die.
