Specifically, the lower bearing mold 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 mold 1. The circumference of the lower positioning arc surface 10 is less than half the length of the circumference of the outer arc of the plastic core a. The circumference of the arc of the upper positioning arc surface 20 is greater than the radius of the plastic core a, and the circumference of the arc of the upper positioning arc surface 20 is less than half of the circumference of the outer circumference of the plastic core a. The plastic core outer circumference surface is not all clasped, which can be applied to general clasping when the outer circumference diameter has difference 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 role in pre-positioning the plastic core a.
Secondly, the lower bearing die 1 is installed on the 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 inserting portion 14 which is sleeved into the T-shaped groove in the top surface of the fixed cross beam 6 is arranged at the bottom of the lower bearing die 1, and the T-shaped inserting portion 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 overturn suspension mold 2 has an upper positioning arc surface 20 corresponding to the lower positioning arc surface 10 one by one. The upper overturning suspension die 2 can be buckled on the lower bearing die 1, and the circle center of the upper positioning arc surface 20 is overlapped with the circle center of the lower positioning arc surface 10.
The upper positioning arc surface 20 is used for holding the plastic core a tightly at the upper side so as to restrain the axis line of the plastic core a to be coincided with the circle centers of the upper positioning arc surface 20 and the lower positioning arc surface 10.
Preferably, the circumferential length of the lower positioning arc surface 10 of the present embodiment is greater than the arc circumference of the upper positioning arc surface 20. By utilizing the length difference design, the plastic core a can be prevented from being damaged by clamping by pressing down and tightly holding the upper positioning arc surface 20, and the radial deformation of the plastic core can be prevented by self-adaptive adjustment after the plastic core is tightly held.
The overturning driving mechanism 3 drives the upper overturning suspended die 2 to be buckled on the lower bearing die 1, so that the lower positioning circular arc surface 10 and the upper positioning circular arc surface 20 surround to form a circular space for radially locking the plastic core.
