Claims

[Scope of utility model registration request]

A clamper is rotatably supported on one side of the upper end of the base housing, and a spring is installed between the clamper pressing end and the side of the base housing to bias the clamper pressing end in the release direction, and the clamper operating end A pushing force is applied by a piston supported by a spring built into the base housing and biased in the upward direction, and the pressing end is pushed down against the spring biased in the releasing direction to maintain the clamped state. On the other hand, a clamping mechanism for a molding die is characterized in that the upper part of the piston storage space of the base housing is configured as an oil chamber that communicates with an oil supply path.
