Note that, if the upper core assembly 120 includes the insert 223, the insert 223 may be fixed to the fixing plate 310 and removed at the same time as the upper core 121. When disassembly of lower die core assembly 220 is desired, the same methods as described above may be used.

It is understood that a handle may be provided on the fixing plate 310, and after the fixing plate 310 is fixed to the upper or lower die core assembly 120 or 220, the handle may be pulled to take out the upper or lower die core assembly 120 or 220. The fixing hole 3121 should be provided at a corresponding position of the mounting hole of the first connector 122 of the upper die core assembly 120 and/or a corresponding position of the mounting hole of the second connector 222 of the lower die core assembly 220. The fixing holes 3121 are formed at the corresponding positions of the mounting holes of the first connecting member 122 of the upper die core assembly 120 and the second connecting member 222 of the lower die core assembly 220 of the fixing portion 312, so that the disassembly and assembly jig 300 can disassemble and assemble the upper die core assembly 120 and the lower die core assembly 220, the disassembly and assembly of the upper die core assembly 120 and the lower die core assembly 220 can be completed only by using one disassembly and assembly jig 300, and the manufacturing cost can be reduced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. Furthermore, the embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
