Unloaded lotus die sinking, matched moulds, two extreme positions for making side core sliding block be moved to during core pulling in the presence of magnetic pull
When, mark is carried out, side core sliding block is then removed and processes 2 hemisphere holes by mark.By 2 positioning pits, coordinate spring catch
Follow closely detent mechanism, the common exact position for positioning side core sliding block during core pulling.
The beneficial effects of the utility model are：The utility model is added using strength ndfeb magnet instead of Conventional limit block
The complicated side core-pulling mechanism of spring or hydraulic means, play buffering, absorbing and control side core sliding block using magnetic force and chute begins
The effect for being in close contact eventually and (avoiding position error caused by the cooperation of gap).Spring pin detent mechanism is simple in construction, manufacturer
Just, exact position of the side core sliding block during core pulling can be automatically controlled.Avoid according to side core sliding block in core pulling process
In displacement by geometric formula calculate or CAD software it is accurate during mould open/close to measure side core sliding block
Accurate calculating and complicated design required for position.The unit absorption weight of the magnet is standard value, when mounted can basis
The weight installation of adsorbed sliding block is one or more, can be applied to different size of side core sliding block.
