[0038] The core pulling piece 11 is fitted and connected to the upper side of the inner surface of the core pulling base 1, and a through hole 12 is opened on the inner surface of the core pulling piece 11, and an inclined slider 13 is installed on the side of the outer surface of the core pulling piece 11, and a slider head 14 is installed on the left side of the outer surface of the core pulling piece 11, and a control tube 15 is installed on the left edge of the outer surface of the core pulling piece 11, and the core pulling piece 11 is provided with an oblique limiting movement mechanism.

[0039] When the injection mold passes through the combined lateral core pulling mechanism, the mold can be opened to stably control the sliding member 9 on the core pulling base 1 to slide, and the position of the core pulling member 11 can be adjusted in coordination with the guide rod 8. When the core pulling member 11 is started, the driving mechanism 17 on the core pulling member 11 can be synchronously controlled to start, and the inclined ejector head 19 can be quickly driven away from the inner side of the product side, so as to effectively control the product molding and use;
