The reason of the deformation of aluminum die casting:
Casting structure is poor;
Open mold is too early, rigid enough;
The top rod is not set properly, and the force is not uniform when the ejection.
Improper gate location or gate thickness is too thick, easy to deform when the gate is removed;
Because the local surface is rough and the resistance is large, product deformation when the ejection;
On the local temperature of the mold is too high, products are not completely cured, ejection force is too large, deformation caused by product.
Treatment method:
Improved aluminum die casting structure;
Adjust the pressure and the time of open mold;
Reasonably set the top position and the number of the top rod, preferably with four, open place;
Changing the gate location, so that the gate has a point, reduce the thickness of the gate, in order to ensure the quality of the product is not easy to deformation of the product when the resection gate;
Strengthen the mold surface treatment, reduce the release resistance;
On the partial mold temperature control, maintains the mold heat balance.
