The production of die casting is inseparable from the die casting die, and the quality of the die directly affects the normal production of the enterprise. A well designed die casting mold can maximize the production efficiency of the equipment, effectively reduce the energy cost of the die casting production, and reduce the reject rate of the die castings.
It is the most direct and reliable way to check the working state of die casting die by using die casting mould test sheet.
1. The movement of die part in the process of mold test should be flexible, stable, accurate and reliable, whether there are skew and stagnation.
2, the cooling water road and hydraulic oil road should be unblocked and no leakage.
3, the mold exhaust is good, whether there is splash in the metal liquid;
4. The relative movement of all the fixed parts of the mold;
5, the slider movement should be stable, the slide block and the wedge tight block should be pressed tight, the contact area should not be less than 3/4, the limit position after the die opening should be accurate and reliable.
6. The ejection rod of the mold is no different, the top out of the back position is normal.
7. There is no abnormality in the heel of the punch, and the top out of the product has no abnormality.
8, the opening mould has no crack, deformation, product parts and other phenomena.
9. The result of the preliminary inspection of the size of the product after the mold is preheated;
