Title:

ROTARY TABLE TYPE RESIN SEALING MOLDING MACHINE

Document Type and Number:

Japanese Patent JPH1076545

Kind Code:

A

Abstract:

To achieve miniaturization while the same work is performed by using the same sealing mold.

A sealing mold 2 is moved to a molding position in an area where two tie rods 3, 3 and 4 are stood by means of a rotary table 8 and clamping of the sealing mold 2 is performed by lowering a movable platen 6 to perform sealing molding. The center B of the sealing mold 2 is located close to the rotational center of the rotary table from the supporting center A of each tie rod 3, 3 and 4. The rotary table 8 can be miniaturized and standing intervals of each tie rod 3, 3 and 4 are small and the whole apparatus can be miniaturized, too. Out of balance of load of each tie rod 3, 3 and 4 caused by disagreement between the supporting center A and the center of sealing mold can be solved by increasing strength by enlarging the diameter of the tie rod 4.
