Claim 0:
1. A method for manufacturing a resin molded product, comprising:
providing a resin molding apparatus, wherein the resin molding apparatus comprises:
a molding mold;
one mold wedge mechanism; and
one mold cavity block driving mechanism;

wherein
the molding mold comprises: one mold, and an other mold;
the one mold comprises: one mold cavity frame member, and one mold cavity block;
the one mold cavity block is movable in the one mold cavity frame member in a mold opening/closing direction of the molding mold;
one mold cavity is formed by a surface of the one mold cavity block facing the other mold and an inner surface of the one mold cavity frame member;
the one mold cavity block is moved in the mold opening/closing direction by the one mold cavity block driving mechanism;
a position of the one mold cavity block in the mold opening/closing direction is fixed by the one mold wedge mechanism;

setting a height position of the one mold cavity block by moving the one mold cavity block to a preset height position by the one mold cavity block driving mechanism;
after the one mold cavity block having been moved to the height position in a direction away from the other mold, fixing the one mold cavity block by the one mold wedge mechanism;
injecting a resin into the one mold cavity; and
performing a resin molding by changing a depth of the one mold cavity by the one mold wedge mechanism and the one mold cavity block driving mechanism after injecting the resin;
wherein the one mold wedge mechanism includes:
an upper mold first wedge member;
an upper mold second wedge member;
an upper mold wedge member power transmission member; and
an upper mold wedge member driving mechanism,

wherein the upper mold first wedge member is connected to the upper mold wedge member driving mechanism via the upper mold wedge member power transmission member, and
the upper mold first wedge member is configured to be slid in a taper direction of a tapered surface of the upper mold second wedge member by the upper mold wedge member driving mechanism;
wherein the resin molding apparatus further comprises:
one mold cavity block holding member to which the one mold cavity block driving mechanism is connected; and
an upper mold second wedge member holding member,

wherein the one mold cavity block holding member is raised by the one mold cavity block driving mechanism until the one mold cavity block holding member comes into contact with the upper mold second wedge member holding member, so as to fix the position of the one mold cavity block.
