Die casting is a casting method of die forging. Die casting die forging process is a process to complete the special die casting die forging. Its basic process is: the cavity of metal liquid is low or high speed casting into a mold, mould have activities of the cavity surface, the metal liquid cooling process pressure forging, can eliminate the blank of shrinkage cavity shrinkage, also make the blank internal organization achieveforging state of crushing grain. Blank comprehensive mechanical performance wassignificantly improved. In addition, the process out of the blank, the outer surface finish to achieve 7 (Ra1.6), such as cold extrusion process or machined out of the surface, with metallic luster. So, we will die forging process called "limit forming process," than "shaping without cutting, less headroom process" a step further. Die forging process has another advantage is, in addition to the production of the traditional casting materials, deformation alloy, forging alloy with it also, produce the structure is very complicated parts. These alloys include: aluminum alloy, aluminum alloy (such as LY11, LY12, 6061, 6063, LYC, LD etc.). The tensile strength of these materials, nearly one times higher than that of conventional casting alloy, foraluminum alloy wheel, frame, hope that the impact of materials for the production ofresistance of components with higher intensity, has more positive meaning.
A brief introduction of pressure casting, die casting or casting, is one kind of the molten alloy liquid pressure into indoor, to the high speed filling steel mold cavity, andmake alloy liquid and the formation of casting solidification under pressure. The main characteristics of die casting method is different from other high pressure and high speed.
①The liquid metal is under pressure to fill the cavity, and solidification at higher pressures, common pressure is 15 100MPa.
②The metal liquid to the high speed filling cavity, usually in the 10 - 50 m / s, and some also can be more than 80 meters / seconds, (through the gate into the cavity of theline speed - ingate speed), so the liquid metal filling time is very short, about 0.01 - 0.2 seconds (depending on the size of castings different) inside can fill the cavity.
Die casting machine, die casting alloy and die casting mould are the three elements of die-casting production, are indispensable. The casting process is the three elements organically be used comprehensively, enabling stable rhythmically and efficientproduction of appearance, good internal quality, size consistent with requirements of the qualified casting pattern or agreement, even the high quality casting.
