密な形状鋳造製品を作成する方法に関するもの。DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention is directed to the manufacture of precision shape-cast products using a material in which a photopolymerizable permanent cake-like resin and a wax pattern sheet are pasted and rolled together. Something about how to create.

脂法。Oral, traditional techniques and interflexion pointsIn the field of dental technology, castings, especially in the case of metal floor coverings, the resin method.
ワックス法とあるが、在来の樹脂法は２液性の熱硬化型
樹脂で硬化速度が速く、又タレ等の為操作性に欠けた。Although it is called a wax method, the conventional resin method uses a two-component thermosetting resin that has a fast curing speed and lacks operability due to sagging.
ワックス法では作業工程も多く、材質上作業模型から直
接離型する事が出来ないので精度上の開運もある。The wax method requires many work steps, and because the material cannot be directly released from the working model, there is also a chance of accuracy.

易になるものである。C9 Object and structure of the invention The object of the invention is to simplify and speed up the work of making molds from models, etc.
The aim is to establish a new molding technology with excellent dimensional accuracy. For this purpose, polystyrene, etc. or other resin powder is blended in an appropriate ratio with the urethane acrylate resin liquid or other resin liquid that is used as the material of the conventional resin method to impart a rice cake-like plasticity. I irradiated ultraviolet rays or visible rays on a material that had added an appropriate amount of a sensitizer that is sensitive to ultraviolet rays or visible rays.I controlled the hardness required for one operation, but the problem was that the back surface on the light irradiation side was rough and unpolymerized. Therefore, in order to improve this point, a wax sheet is attached to the back surface and rolled to compensate for the defect and make the molding work easier.

上極めて有益なものである。EFFECTS OF THE INVENTION Since molds can be easily and quickly made directly from models without relying on molds, precision casting of various dental products such as denture bases, various industrial parts, and double rings for arts and crafts are possible. Furthermore, it is extremely useful for industry, as it enables the establishment of various new molding techniques.

If a patterned sheet is formed using only this mochi-like resin, even if the light-irradiated side has a mirror-like finish, the back side often becomes rough. Therefore, by applying a wax pattern sheet to the back side and rolling it, it is possible to compensate for each other's defects and to manufacture products with improved operability and precision.
