Mold apparatus, molded product, method of molding the same, and molding machine

摘要

An object is to provide a mold apparatus which can prevent inclination of a machining member to thereby improve quality of molded products. The mold apparatus includes a first mold unit; a second mold unit; a sprue bush ( 24 ) disposed in one of the first and second mold units and having a sprue ( 26 ) for charging a molding material into a cavity space (C); a machining member disposed in the other of the first and second mold units in such a manner that the machining member can be advanced and retracted, the machining member performing a predetermined machining for a prototype of a molded product when the machining member is advanced; and a bush ( 47 ) disposed radially outward of the machining member to surround the machining member and having a flow passage ( 55 ) which is formed in a front end portion thereof and through which a temperature control medium flows. Since the flow passage ( 55 ) through which a temperature control medium flows is formed in a front end portion of the bush ( 47 ), a temperature control flow passage is not required to be formed in the front end portion of the machining member. Accordingly, since a support member can be disposed at a location offset toward the front end of the bush ( 27 ), generation of inclination of the machining member can be prevented.
