1.Casting information
casting name: burner
casting requirements:internal requirement
casting process:
Die Casting machine tonnage:300T
 alloy material:aluminium alloy
2.Casting problem
when open the mold,the middle part was broke away,see the defect picture
3.Casting pictures

4. Casting analysis
1.This tubular feature part is isolated in the front mold cavity and is not easy to be molded. Because the tube wall is not formed well and the strength is low, it is easy to cause the core’s holding force greater than the product’s strength, resulting in mold breaking and sticking to the front die.
2, due to the adhesion of the front die, the mold can not work continuously, low production capacity, can not be normal mass production.
5.Improving measures
Six reinforcing ribs are added to the characteristic side of the tubular column of the front mold to improve the forming effect and increase the strength of the product. After improvement, it will not stick to the front mold, improve the continuous operation performance of the mold, and obtain higher productivity and pass rate.
Disadvantages: The increased ribs should be removed after processing, resulting in a certain processing cost.
6. Tips
For the core’s holding force
It can increase the point cooling of the core, coating treatment, increase drafting, reduce the casting pressure, etc., to reduce the holding force to a certain extent.
