Abstract

PURPOSE: To provide the titled metal mold removing burrs easily constituted by forming a molding cavity by providing a concave molding surface to an upper and a lower molds and forming a burr removing space to a periphery thereof to cure a resin protruded from the molding cavity in the burr removing space.
CONSTITUTION: Molding surfaces 3a, 3b are provided in a concave shape to the lower mold 2 and the upper mold 1 corresponding to a molded product 8 to form the molding cavity 4 and a recessed groove 10 is provided over a total periphery around the molding surface 3b and combined with a flat surface 9 to form the burr removing space 5. If the molded product 8 is cured completely, the molded product 8 is pressed to the lower mold 2 by a push pin or the like from the upper mold 1. Because burrs are entered into the recessed groove 10 to be cured and separated by pulling from S1 part and raised along with the upper mold 1, any burrs are not attached to the flat surface 9 of the lower mold 2. The cleaning of the upper mold 1 is carried out by blowing a high pressure air to the recessed groove 10 by a high pressure air gun to scatter said burrs.
