Abstract
PURPOSE: To make the solification of the extinction pattern shorter in time and prevent the deterioration of the resin mold forming the extinction pattern with resin layers for the surfaces in contact with the extinction pattern and the resin mold of the mixed layers of resins and metal powders in other portions.
CONSTITUTION: A negative pattern 1 and a flask 2 on the outer side thereof are set on a molding board 3. Next, epoxy resin is coated on the outside corners of the negative pattern 1, the inside corners of the flask 2, between the negative patterns 1 and flask 2, etc. to form the 1st resin layer 4. Next, epoxy resin is coated on the top surface after drying, whereby the 2nd resin layer 5 is formed. Mixture of epoxy resin and metal particles such as of Al is coated at the corner angle parts by the negative pattern 1 to form corner-angle-reinforcing layers 6. After standing at ordinary temperature, the mixture of Al particles and epoxy resin is packed in the flask 2 and is set to form resin-metal particle mixed layers 7. After the molding, the negative pattern 1 and flask 2 are removed, whereby the one portion 8a of the resin mold wherein the surfaces in contact with the extinction pattern are resin layers 4, 5 and the inside body is the resin-metal particle mixed layer 7 is produced. Likewise, the other portion 8b is produced and both are mated to obtain a resin mold 8.
