As the utility model discloses an optimal technical scheme, the spacing counter bore that the cooperation through-hole bottom of lower core set up is the toper counter bore, and is the toper boss with spacing counter bore complex spacing boss, the degree of depth that highly is less than or equal to the toper counter bore of toper boss, toper counter bore and toper boss match to reach the purpose that makes things convenient for the riveting axle to insert and self-centering.
As the utility model discloses an optimal technical scheme, the spacing counter bore that the cooperation through-hole bottom of lower core set up is cylindrical counter bore, is cylindrical boss with spacing boss of spacing counter bore complex, and the degree of depth that highly is less than or equal to cylindrical counter bore of cylindrical boss.
As the preferred technical scheme of the utility model, the riveting axle is made for the round steel, and the material is cheap reliable.
The utility model discloses a ladle is with special type brick cup mould connecting device's beneficial effect:
1. the utility model discloses a ladle is with special type brick cup mould connecting device abandons screw nut's connection principle, has changed the easily damaged production methods of production difficulty, mould core in the past, has improved the durability of mould core, has reduced mould maintenance frequency and cost of maintenance.
2. The utility model discloses a ladle is with special type brick cup mould connecting device has reduced maintenance workman's intensity of labour, has reduced down time, has directly improved production efficiency, can produce good economic benefits.
