摘要

PURPOSE: A stacked mold and a method of manufacturing provided to reduce the manufacturing time of the injection molding product and failure rate by heating or frozen the melted plastic liquid which is inserted in cavity at the same time in all areas. CONSTITUTION: A staked mold comprises a mold unit(100), a cavity, and grooves(120). The mold unit is formed by welding a plurality of panel-shaped members(110). The cavity is formed in the mold unit.
