Abstract:
A non-pneumatic pressure molding apparatus comprising:a furnace defining a heating space for accommodating a mold assembly including a mold body charged with a raw material to be molded, and a pressure piston for pressurizing the raw material;heating means for heating the heating space; andload imposing means for imposing a load on the pressure piston to mold the raw material, wherein the load imposing means includes at least one weight means and weight supporting means, and the weight supporting means is selectively set in a load-free state in which the weight supporting means supports the weight means so that the weight of the weight means is not imposed on the pressure piston, and a load imposed state in which the weight supporting means releases the support of the weight means so that the weight of the weight means is imposed on the pressure piston.
