The two bosses 21 are in contact with the first buried terminal 5 and the second buried terminal 6, respectively. The core back insert 4 includes a horizontal plate portion 41 and a vertical plate portion 42 connected to each other, the horizontal plate portion 41 is located between the first embedded terminal 5 and the second embedded terminal 6 and the front core 3, and the vertical plate portion 42 is located between the first embedded terminal 5 and the second embedded terminal 6.
The working principle of the invention is as follows:
firstly, opening a front mold of the mold once, driving a slide block 2 to move backwards by a system, and withdrawing the safe distance of the barbs of a first embedded terminal 5, a second embedded terminal 6 and a third embedded terminal 7;
continuing opening the front mold of the mold to drive the core-pulling insert 4 to move backwards to reach a set distance S1;
step three, parting and opening the mould at one time on the parting surface of the front mould core 3 of the mould, and limiting the mould opening distance S2;
driving by an external power oil cylinder to drive the front die core 3 to move laterally, and withdrawing the safe distance of the barbs of the first embedded terminal 5, the second embedded terminal 6 and the third embedded terminal 7;
step five, performing secondary normal parting and mold opening on the parting surface of the front mold core 3 of the mold until the set mold opening distance S3 is reached;
