Abstract
A lens molding apparatus of the present invention includes: a mold having a transfer surface for transferring a predetermined lens shape to a dielectric resin; a mold having a transfer surface for transferring a predetermined lens shape to the dielectric resin; a support device moving the mold; a heating device heating the dielectric resin so as to form a resin molded product, the dielectric resin having been supplied on the transfer surface; a DC power source forming an electric field by application of direct-current voltage between the mold and the mold; and switches switching a direction of the electric field between a direction from the mold to the mold and a direction from the mold to the mold.
Claims3
A resin molding method comprising the steps of:
- (a) curing a dielectric resin material so as to form a resin molded product while a second transfer surface of a second mold is being pressed against the dielectric resin material, the dielectric resin material having been supplied on a first transfer surface of a first mold;
- and
- (b) separating the second transfer surface from the resin molded product,
- the step (a) including the sub-step of forming an electric field in a predetermined direction by application of direct-current voltage between the first mold and the second mold,
- the step (b) including the sub-step of forming an electric field in a direction that is opposite to the predetermined direction between the first mold and the second mold.
A resin molding method comprising the steps of:
- (a) curing a dielectric resin material so as to form a resin molded product while a transfer surface of a mold is being pressed against the dielectric resin material, the dielectric resin material having been supplied on a base plate;
- and
- (b) separating the transfer surface from the resin molded product,
- the step (a) including the sub-step of forming an electric field in a predetermined direction by application of direct-current voltage between the base plate and the mold,
- the step (b) including the sub-step of forming an electric field in a direction that is opposite to the predetermined direction between the base plate and the mold.
