Die casting die thimble often broken, who knows what a good way to solve it?
It should be with the product, the broken needle top shows too much resistance, no deformation strain check beer pieces where appropriate to improve the model, our factory had tens of thousands of sets of die, not many often broken needles.
Generally with thimble high temperature have certain relation. If you let the center down, you can effectively control the occurrence of events.At present, the market is divided into grease and lubricating oilWe are in the area of lubricants, that is, sprays.Have extensive experience in customer service in die casting plantMany customers are using our peacock brand high temperature resistant thimble lubricantIt can solve the problem of high temperature of thimble in forming time of aluminum alloy, zinc alloy and other materials.I hope I can help you.
1. Increase the thimble diameter2, the thimble adopts better material SKD61 heat treatment3, see if the process can be improvedNothing great, we used to do die casting die thimble is also easy to break.
Breaking the needle shows that the resistance is too great when the top is pulled out, the hardware is checked and there is no strain in the deformation, so the slope of the die is properly improved.Die casting die is a method of casting liquid die forging, a process in a special die casting die forging machine. Its basic process is: first cavity liquid metal in low speed or high speed casting filling into the mold, mold cavity surface activity, it is with the metal liquid cooling process pressure forging, can eliminate the blank of shrinkage cavity shrinkage, also make the blank internal organization of forging state of crushing grain. The comprehensive mechanical properties of rough parts have been remarkably improved.
