Cause material incipient scorch；It is provided with lead and fairlead between described cope match-plate pattern and middle template, between middle template and lower bolster, leads
Coordinate to using inclined-plane between post and fairlead, it is ensured that accurate between cope match-plate pattern and middle template, between middle template and lower bolster
Location
As improvement, it is separately installed with electric heating tube in described upper electric hot plate and lower electric hot plate, to the first die cavity and the second die cavity
Omnidistance heating；The thickness of described cope match-plate pattern and lower bolster thickens, and plays mould heat insulation effect.
As improvement, the upper die and lower die surface of described first die cavity and the second die cavity uses nano level vacuum titanizing: resistance to
Wet, raising surface abrasion ability, anti-sticking to mould.
As improvement, described middle template is provided with knock-pin, connects automatic ejecting mechanism, improve production efficiency.
Compared with prior art, it is an advantage of the current invention that: this bilayer O forming die structure is simple, molding effect
Good；It is provided with in the lower mold of described first die cavity and the second die cavity and blocks hopper, prevent bar material from deflecting away from when sulfuration and causing
Product lacks material；It is provided with four springs on described lower bolster, it is ensured that between middle template and lower bolster, have a certain distance, prevents from putting
Put the material in the second die cavity to heat due to long pressurized before sulfuration and cause material incipient scorch；Described cope match-plate pattern and in
It is provided with lead and fairlead between template, between middle template and lower bolster, between lead and fairlead, uses inclined-plane to join
Close, it is ensured that the precise positioning between cope match-plate pattern and middle template, between middle template and lower bolster, described first die cavity and the second die cavity
Upper die and lower die surface use nano level vacuum titanizing, improve surface moisture-proof, antiwear property, prevent material sticking to mould；This pair
Layer O mould is particularly suitable for manufacturing the bigger O of size, improves product quality and work efficiency.
