Abstract
The invention discloses a mold core combined structure. The mold core combined structure comprises a front mold core plate, a mold cavity plate, a rear mold core plate, a main runner hole, a transverse runner and two insert cavities. The main runner hole communicates with the transverse runner. The two insert cavities are located on the left side and the right side of the transverse runner correspondingly. Two concealed material inlets which are in bilateral symmetry are further formed in the mold cavity plate. A plurality of positioning pin holes are further formed in the front mold core plate, the mold cavity plate and the rear mold core plate. According to the mold core combined structure, the insert cavities in the middle of a mold core assembly are designed to be in a crescent shape and matched with crescent-shaped inserts so that the probability that the inserts are bumped and damaged during assembling can be lowered to the maximum degree, and mounting and dismounting can be facilitated; and the insert cavities in the middle of the mold core combined structure are machined through slow-feeding wire cutting, the three plates are positioned through positioning pins and then machined in place through slow-feeding wire cutting at the same time, therefore, the assembly errors are effectively avoided, and the accuracy can be improved remarkably.
