At this time, the fine positioning pin 548 of the lower mold core 54 of the town's mold core was roughly aligned with the positioning pin hole 446 corresponding to the upper mold core 44. During the further closing process, due to the magnetic 11 Under the action of the repulsive force of the upper and lower directions of the member 6, the lower mold core 54 and the lower mold base 52 remain in a non-contact magnetic floating state. Therefore, during the closing process, the fine positioning pin 548 and the positioning pin hole 446 can cooperate to lower the lower mold core 54. A slight adjustment is made in the opening 520 of the mold base 52 to finally achieve fine positioning, that is, the upper mold core 44 and the lower mold core 54 are closed, and the cavity 442 of the upper mold core 44 and the cavity of the lower mold core 54 are 542 °. Four cavities are formed. During the fine positioning process, since the lower mold core 54 is in a floating adjustable state, the fine positioning pin 548 is not worn by the interference of the guide post. _ It can be understood that the mounting position of the magnetic member 6 is not limited to the four corner positions of the opening 520 of the lower die holder 52 and the four corner positions corresponding to the lower die 54 , and may be located at a proper position around the lower die & 52 opening 520 and the lower die The position corresponding to 54 is as long as the lower mold core 54 is balanced.
