てしか用いられず、用途が制限されていた。Conventionally, a photocurable molding material was put into a metal mold with an open top, for example, and molded by irradiating it with ultraviolet rays from above, but instead of irradiating it with ultraviolet rays from only one direction. For this reason, the photocurable molding material in the shaded areas where ultraviolet rays are not exposed will not harden.For this reason, especially in the case of liquid photocurable molding materials, it cannot be used as a mere coating agent or adhesive for articles. Its use was limited, as it was only used as a dehydrating agent.
本発明はこのような従来の問題点に鑑みてなされ泥もの

光硬化性成形材料の成形方法を提供することにある。The present invention was developed in view of these conventional problems.The purpose of the present invention is to use an ultraviolet-transparent mold to allow ultraviolet rays to be irradiated from all directions, thereby achieving rapid and complete photocuring. It is an object of the present invention to provide a method for molding a photocurable molding material, which enables the molding process to be carried out.

It is characterized in that the photocurable molding material (1) is photocured by irradiation with K ultraviolet rays and molded. The photocurable molding material +11 in the present invention may be any composition having a photocuring function, and may include photocurable resins such as unsaturated polyester resins, acrylic resins, and epoxy resins, as well as acrylic acid, if necessary. It is made by blending photopolymerizable polymers or oligomers such as acrylamide, styrene, trimethylol-based triacrylate, photosensitizers such as pen-fin compounds and becisophenoy compounds, and other pigments.

As the ultraviolet-transparent mold (2), a mold 7 made of glass or a transparent synthetic resin such as acrylic resin, styrene resin, polymethylpentyl, etc. can be used. However, since it is usually heated to stop photocuring, it is preferable to use a synthetic resin with a low melting point and softening point. preferable.

Therefore, the photocurable molding material can be quickly and completely photocured without forming a so-called shadow area in the mold, and it can be suitably used when inserting precise parts. .
