Die moldDie mold die casting production is one of the three major elements, structure the correct reasonable mould is die casting production could be carried out successfully prerequisites, and ensure the

quality of casting (plane percent of pass) play an important role. Due to the characteristics of the die casting technology, the correct selection of the process parameters is a high quality casting decision factors,

while mould is able to correct selection and adjustment of technological parameters in the premise, mold design is essentially for die casting production may appear various factors expected comprehensive

reflection. If the mould design is reasonable, it is in actual production problems encountered in the less, the plane casting high qualified rate. Conversely, mold design is not reasonable, cases of a casting

design dynamic fixed die package force is basic and same, and pouring system mostly in fixed mode, and put on shot after punch can't feed the pouring south die casting machine on production, unable to

normal production, casting have been glued to the set on a module. Although fixed model cavity finish played a very light, because of the cavity is deep, still appear glued to the fixed die on the phenomenon. So in

the mold design, must fully analyze the structure of castings, familiar with the operation of the die casting machine process, to understand die casting machine and process parameters to adjust the possibility of

master in different cases filling characteristics, and consider the mould the method of machining, method of drilling and fixed form, to design the practical and meet the production requirements of the mould. The

beginning has been said before, liquid metal filling time is very short, metal liquid than pressure and flow rate is very high, the die mold, work conditions are very bad, plus chilling excitation hot alternating stress

of the impact, the service life of the die has a great influence. The service life of die is usually refers to through the careful design and manufacturing, in normal conditions, combined with good maintenance

appear natural damage, in can't repair before and scrap, die casting modulus (including die casting production of waste product number).
