Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, a mold base plate 1 is arranged below a mold main body 2, a material pushing plate 3 is arranged on one side of the top of the mold base plate 1, an upper ejector plate 4 and a lower ejector plate 5 are arranged between the mold base plate 1 and the mold main body 2, and the upper ejector plate 4 and the lower ejector plate 5 are matched with each other;

the top of the die bottom plate 1 is fixedly connected with a plurality of supporting columns 21, driving pieces 6 are arranged at the centers of the supporting columns 21, and the driving pieces 6 can be hydraulic rods, electric telescopic rods and the like;

the support sleeves 22 are arranged on the peripheries of the support columns 21, and the support sleeves 22 are distributed in an array manner and are embedded in the lower ejector plate 5;

the top of the support sleeve 22 is designed with a flaring, the inner periphery of the flaring is provided with a flaring part 24, two sides of the outer periphery of the flaring part 24 are both provided with notches 41, and the outer periphery of the notch 41 is clamped with a slide block 42;
