Abstract

PURPOSE: To upgrade a dimensional accuracy of resin molded product by providing an easily breakable notch for the runner connecting with a plurality of resin blocks on the substrate.
CONSTITUTION: A part of the runner 7 joining a number of resin blocks 2A, 2B defined on the substrate 1 is provided with a notch 8 breakable by the external force or self-breakable by the thermal shrinkage during the thermal shrinking period. Since the runner 7 can be breakable by the internal force or the external force, respective resin block 2A, 2B is contracting each other by the thermal shrinkage of the runner 7, which may not cause to downgrade the dimensional accuracy. Besides, by providing the notch 8 for both ends of the runner 7, the runner 7 can be removed easily from the molded product for reusing the stock material.
