A mold structure includes an upper mold and a lower mold. The upper mold is installed with an upper mold core, and the lower mold is installed with a lower mold core. A mold cavity is formed between the upper mold core and lower mold core. A mother plate disposed in the mold cavity is replaceably coupled to one of the mold cores. The mother plate includes a glass substrate with a metal film thereon. The metal film defines a pattern that is transferred to the plastic material molded in the mold cavity.
