摘要

The present invention relates to an undercut processing apparatus and an injection mold comprising the same. The undercut processing apparatus comprises: a fixed central portion; a pair of first dividing members; and a circumferential portion divided by a pair of second dividing members and having a molding band formed on an outer circumference thereof, wherein the circumferential portion includes: a core portion disposed at the outer circumference of the central portion; a support portion for supporting and lifting the first dividing members; and a push piece for lifting the second dividing members. Injection products are molded along the outer circumference of the pair of first dividing members and the pair of second dividing members, wherein the pair of first dividing members are lifted up by the support portion and are fallen from an inner circumference of the injection products, and the second dividing members are lifted by the push piece and thus fall on the inner circumference of the injection products.;COPYRIGHT KIPO 2019
