Abstract
A form for manufacturing a resin mold has a frame housing a master model corresponding in shape to a product to be molded and having a space defined therein for receiving the ultraviolet-curable resin poured therein around the master model. The frame is made of an ultraviolet-permeable material. When ultraviolet radiation is applied outside of the frame to the frame, the ultraviolet-curable resin in the frame is cured into a resin mold. The resin mold can easily and quickly be manufactured. The resin mold can also reliably be clamped by a clamping jig for producing a high-quality molded product.

A form for manufacturing a resin mold by pouring an ultraviolet-curable resin and curing the ultraviolet-curable resin to produce the resin mold by exposure to ultraviolet radiation, comprising:
- a frame housing a master model corresponding in shape to a product replica and having means for supporting said master model within said frame such that a space is defined therein for receiving the ultraviolet curable resin which is poured into said frame to surround the master model;
- said frame being made of an ultraviolet permeable material,
- wherein after curing of said ultraviolet-curable resin, said resin is removed from said frame and said master model is removed from said ultraviolet-curable resin, to thereby produce said resin mold having a cavity therein corresponding in shape to said master model.
A clamping jig for clamping a resin mold for receiving an ultraviolet-curable resin poured therein which is to be cured into a product by exposure to ultraviolet radiation, comprising:
- ultraviolet-permeable first and second sandwiching plates adapted to be positioned on respective opposite surfaces of said resin mold;
- a plurality of ultraviolet-permeable spacers disposed between confronting surfaces of said first and second sandwiching plates outward of said resin mold;
- and
- fastening means for integrally clamping said first and second sandwiching plates together through said spacers;
- said first sandwiching plate having an opening for introducing said ultraviolet-curable resin therethrough into said resin mold.
A clamping jig for clamping a resin mold for receiving an ultraviolet-curable resin poured therein which is to be cured into a product by exposure to ultraviolet radiation, comprising:
- ultraviolet-permeable first and second cases adapted to be positioned on respective opposite surfaces of said resin mold and openable and closable with respect to each other;
- and
- fastening means for integrally clamping said first and second cases together with said resin mold housed therein;
- said first case having an opening for introducing said ultraviolet-curable resin therethrough into said resin mold.
