　　Aluminum alloy die casting mold 4 major fault solution

　　1, stick mold.

　　After the mold is removed, use a chisel to chisel away the adhesive mold product little by little, there is a risk of chiselling the mold and damaging the mold.

　　Another way, you can use a spoon to pour hot aluminum alloy on the casting of the adhesive mold, so that the casting thermal expansion, and then the casting top out or pry out, need to pay attention to safety.

　　2. Core fracture.

　　The mold is removed and the core is replaced.

　　The core can be designed as a front-mounted type, that is, the core tail is designed as a thread, and the corresponding thread is also played on the insert of the mounting core, so that the core can be installed in front of the core when the core is broken, without unloading the mold.

　　3. The core is bent.

　　Check the core hole of the casting with quality requirements (there are strict dimensional tolerances, and the core hole is not machined), and if the drawing die is found, the core is bent, as shown above.

　　4, the top rod is broken.

　　Remove the mold and replace the ejector rod.
