Claim:
A mold for an injection molding apparatus, comprising: a first mold half and a second mold half configured to be opened or closed in an opening or closing direction relative to each other and configured to form a cavity to be filled with photo-setting resin when the first mold half and the second mold half are closed, and wherein the first mold half includes: a light source configured to emit light, a first member configured to transmit the light emitted by the light source to the cavity; a second member configured to reinforce the first mold half and including a surface which faces the second mold half and a depressed portion which is formed in the surface, wherein the first member is provided within the depressed portion and movable relative to the second member along the opening or closing direction; and a third member disposed between the first member and a bottom portion of the depressed portion of the second member, arranged on a side in the opening direction of the first mold half relative to the first member and on a side in the closing direction of the first mold half relative to the second member, and configured to support the first member to relieve through compressive deformation a clamp force loaded on the first member from the second mold half when the mold is closed; the mold further comprising an actuator provided in a die plate of the first mold half that is configured to compress the first member relative to the second member to increase a clamp force.
