Specifically, the lower bearing die 1 of the present embodiment has a lower positioning arc surface 10, and the lower positioning arc surface 10 is disposed at the top of the lower bearing die 1. The arc circumference of the lower positioning arc surface 10 is smaller than half of the outer arc circumference of the plastic core a. The circular arc circumference of the upper positioning circular arc surface 20 is larger than the radius of the plastic core a, and the circular arc circumference of the upper positioning circular arc surface 20 is smaller than half of the outer circumference of the plastic core a. The mode that the outer circumference of the plastic core is not fully hugged can be suitable for general hugging when the outer circumference diameter is different due to the processing error of the plastic core.
The lower positioning arc surface 10 is used for receiving blanking of the plastic core a so as to play a pre-positioning role on the plastic core a.
Secondly, the lower bearing die 1 is mounted on a fixed cross beam 6, the fixed cross beam is made of aluminum profiles, a plurality of T-shaped grooves 60 are respectively formed in the circumferential direction of the transverse section of the fixed cross beam 6, at least one T-shaped insertion part 14 sleeved in the T-shaped groove on the top surface of the fixed cross beam 6 is arranged at the bottom of the lower bearing die 1, and the T-shaped insertion part 14 is matched with the T-shaped groove, so that the lower bearing die 1 is fixed.
As shown in fig. 1-2, the upper overturning suspended die 2 is provided with upper positioning arc surfaces 20 which are in one-to-one correspondence with the lower positioning arc surfaces 10. The upper overturning suspending die 2 can be buckled on the lower bearing die 1, and at the moment, the circle center of the upper positioning arc surface 20 and the circle center of the lower positioning arc surface 10 are overlapped.
The upper positioning arc surface 20 is used for tightly holding the plastic core a at the upper side so as to restrict the coincidence of the axial lead of the plastic core a and the circle center of the upper positioning arc surface 20 and the circle center of the lower positioning arc surface 10.
Preferably, the circumferential length of the lower positioning arc surface 10 of this embodiment is greater than the circumference of the arc of the upper positioning arc surface 20. By means of the design of the length difference, the plastic core a can be prevented from being clamped by pressing down the upper positioning arc surface 20 and is tightly held, and the plastic core a can be prevented from being deformed in the radial direction by self-adaptive adjustment after being tightly held.
The overturning driving mechanism 3 drives the upper overturning suspension die 2 to be buckled on the lower bearing die 1, so that the lower positioning arc surface 10 and the upper positioning arc surface 20 are surrounded to form a circular space for radially locking the plastic core.
By using the overturning driving mechanism 3, the upper overturning suspended die 2 can be conveniently opened and the upper overturning suspended die 2 can be conveniently closed, so that the plastic core can fall into the lower positioning arc surface 10 timely and rapidly.
Secondly, it can make the plastics core fall from the upside of lower location arc surface 10 to upset drive it to reduce the blanking degree of difficulty and further improve blanking efficiency.

As shown in fig. 1 to 2, the stopper mechanism 4 is fixed to the upper turnover suspended die 2 and contacts with the upper side opening of the inclined space 21, so that the free end of the upper positioning circular arc surface 20 can be prevented from contracting radially inward. The stop mechanism 4, which is blocked at the upper side opening of the inclined space 21, provides a blocking force to prevent the plastic core from being pinched due to the fact that the radius is not equal to the radius of the plastic core caused by the shrinkage of the free end of the lower positioning circular arc surface 10, and even forces the plastic core to deform radially. That is, this structure of the present embodiment can make the radius of the lower positioning arc surface 10 stable and ensure the degree of coincidence of the final clamping surface.
The detection assembly 5 is arranged on the upper overturning suspended die 2, and the detection assembly 5 is in contact with the outer circumferential surface of the plastic core a after the upper overturning suspended die 2 is buckled on the lower bearing die 1.

By utilizing the synergistic effect of the locking buckle 22, the right angle and the upper protruding block 11, the overturned self-locking can be realized so as to remove the rest locking, and in this way, the production efficiency can be greatly improved, and meanwhile, the locking requirement of detection can be met.
Secondly, the concave-convex matching mechanism is arranged between one side of the upper overturning suspending die 2 far away from the inclined space 21 and the lower bearing die 1. Further, the concave-convex matching mechanism comprises an upper convex part 12 arranged at the other end of the lower positioning arc surface 10, an upper groove 23 is arranged at the bottom of the upper overturning suspension die 2, and the upper convex part 12 is matched with the upper groove 23 in a concave-convex mode.
