Aluminum Die Casting Part
Production of aluminum die casting die is one of the three elements
structure reasonable mold die-casting production can proceed smoothly, prerequisites, and guarantee the quality of castings hand ( machine under qualified rate ) plays an important role in.
Due to the characteristic of the die casting process, the correct selection of the process parameters is getting high-quality casting decision factors, while the mold is able to correctly select and adjust the parameters of the premise, the mold design is essential to die casting production of various possible factors are expected to reflect the integrated. Aluminum Casting If the mold design is reasonable, is encountered in the actual production problems, the high qualified rate of casting machine.
Conversely, the mold design is not reasonable, case casting design moving mould parcel force is basically the same, but mostly in the fixed mold gating system, and put the shot after punch can not feed the die casting machine production, cannot be produced normally, castings have been stuck on the fixed die. Although the fixed mold cavity finishes playing very light, because the cavity is deep, still stuck in the fixed mold phenomenon. So in the process of design, we must make a comprehensive analysis of casting structure, familiar with the die-casting machine ‘s operating process, to understand the die casting machine and process parameters can be adjusted odds, lies in the different situations and to consider the mold filling characteristics, processing methods, drilling and fixed form, in order to design a practical, satisfy the production requirements of the mold.
The beginning has been told, the filling time is very short, the liquid metal pressure and flow rate are very high, the die is an extremely poor working condition, coupled with the rapid cooling and heating of the alternating stress impact, both on the service life of the die has a great influence on. Aluminum Die Casting The service life of the die is usually through careful design and manufacture, under normal use, combined with good maintenance under the natural damage cannot be repaired, in which the scrapped before, die-casting module (including the casting production of scrap number).
