The correct use of hardware mold and extend the service life of mould proper maintenance, maintenance is an important measure.
The metal mould should be paid attention to when using the following aspects: (
On the hardware mold during installation to ensure the balance of the mould lifting, prevent excessive tilt of upper die to guide sleeve fracture.
Outfit, removing the elastic stripper plate, should tighten or loosen alternately discharge screw, ensure that the stripper plate on the balance and fall.
Mould parts removed, should pay attention to the original state, reset when ready to facilitate loading mode.
To replace the punch, should be put people die, the punch check whether they fit clearance fit.
To punch the total length shorter after repair, after add plate to check its length is appropriate, to avoid interference with the stripper plate.
Mold for many times after disassembling, positioning pin hole may be due to wear and make the uneven blanking clearance, can be used to adjust the shift.
Replace spring and rubber, should confirm the size and the amount of compression is appropriate, so as to avoid convex touch bend and break.
Hardware mold maintenance factors should be considered: mold parts lubrication on a regular basis, blade and drawing die lubrication on a regular basis, timely cleaning waste, keep the mold clean, regular check mold springs, rubber and the guidance of damage or failure, replace if necessary.
