Preferably, the expander bolt is threadably secured with elastic piston ring.Pass through expander bolt and elastic piston ring spiral shell
Line connection is easy to expander bolt to remove.
Preferably, the centrally disposed centre bore of moving die insert.By setting centre bore to be easy to expander bolt to install more
Change.
Compared with prior art, the horizontal cold pressing chamber aluminum alloy die-casting die of the elastic piston ring structure core utilizes horizontal cold
The axial movement produced during pressure chamber die casting machine hydraulic jack folding and active force, pass through elastic piston ring, round table-like expander, return bullet
The member transforms such as spring are that radial forces and radial expansion change, so as to reach tensioner or unclamp inserts and the purpose positioned, profit
Carry out die casting with the technology mould, threaded insert die casting preset position precision can reach GB/T1184-1996 machined shapes and
The class precision of position of related features 8, new energy electric vehicle hub motor outer rotor housing magnetic guiding loop inserts die casting coaxial accuracy is reachable
To 9 grades of GB/T1184-1996 machined shapes and position of related features, axial offset is controlled within 0.2mm, realizes inserts pressure
That casts is accurately positioned.
