Advanced equipment is the element that makes sure product quality is indispensable admittedly, but it is likewise special and important that the mould is casting medium action. Produce a business to component of aluminium alloy car especially for, the effect that the accuracy of the mould and wear measure to producing quality is very apparent. Black metal is cast, mould more it is to form casting mould antrum, itself of general situation mould is not contacted with metallic fluid directly, cast to the metalloid pattern with mixed appearance especially more such, what contact with glowing metal fluid is modelling material, basically be molding sand, this makes modelling material becomes the main factor that affects cast quality. And aluminium alloy gravity is cast different, because aluminium alloy melting point is inferior, it is good to cast function, be in mass-produced when, the appearance of cast is formed directly by the mould commonly, lid of the aluminium alloy cylinder body that is like engine, crock, this is helpful for improving labor productivity not only, and more important is through adjusting the mould differs the temperature of place distributings, will control the constituent structure of cast and grain bulk, improve cast quality, in the meantime, avoided the environment that use modelling data in great quantities and brings to pollute, improved the labor condition of the workshop. As cast appearance complex degree differs, aluminium alloy gravity casts a mould also each are not identical. Even if same part, use different foundry technology, mould form often also differs, but anyway, aluminium alloy gravity casts a mould or have its general character. Above all, must choose proper foundry technology, the actor bad of foundry technology matters to cast quality and craft to manufacture directly the discretion of rate. Home has some of mould mill, already began to use caky imitate to undertake foundry technology subdesign, fill through be opposite model the computer simulation with caky process, the hot knot place that discovers easy generation casts blemish gives overcome, this pair raises the dependability of mold design, prevent the do poorly done work over again with needless in debugging a process mould effectively, it is very important and effective. Next, the mould should have good look to heat up ability. Accord with the thicker mould bases of the requirement and module, assure effectively be mould life not only, and the adjustment of field of the temperature in process of successive to the mould job has very main effect. Factory of a few moulds, to reduce cost, managing with makings, reduce the effective ply of the mould blindly to reduce the goal of weight in order to achieve, this reduced little imagine greatly not only the service life of the mould, and make cast is out of shape easily, affect cast dimension precision, serious when will cause cast rejection of lot, to cast a factory to cause a loss, more serious is the reputation that damaged mould factory oneself. The 3rd, the mould should have more reliable refrigeration system and unplug air system. Pass refrigeration, can improve labor productivity effectively not only, and cooling rate of cast of field of adjustable cast temperature, control, affect cast interior to organize structure and grain dimension, implementation to dominate the end of casting machine function effectively then. Just as its name implies, unplug gas, it is factitious the gas of interior of ground general antrum is discharged model air hole arises with reducing cast outside antrum kind the likelihood of blemish. In the meantime, the model that also can adjust local zonule through adding outfit venting plug is lukewarm, have very main effect to prevent and overcoming aluminium alloy craze and depression. The 4th, must want to the mould tabulator that matchs with casting machine photograph and convenience mould install a system. Tabulator is to assure cast dimension not only, decrease wrap around seam the crux with burr, and also be the crux that makes sure casting machine works normally, can say, the mould does not have good tabulator, do not have good eligible cast. The mould must facilitate install and disassemble, because aluminium alloy gravity is cast, the time with proper every other must tear open next moulds to new spray expects and build a model, if disassemble no-go, certainly will increases labor strength of the worker, take up more work time, reduce crop and efficiency. To casting a factory for, high grade mould means high grade cast, mean inferior cost, higher production value and profit. Current, development of domestic mould industry is very rapid, only aluminium alloy gravity casts die manufacturer not to issue hundreds of, and of the development as automobile manufacturing industry and foreign capital swarm into, no matter die manufacturer is dimensions or technical actual strength also are in grow day and day, as CNC Machining equipment popularize application, the treatment level of mould industry and abroad already did not have how old difference, a lot of mould factories also have more advanced detect equipment, but concept of our level of management, design, management concept and foreign person of the same trade have difference than returning, mould material and method of heat treatment aggrandizement also lag behind at the developed country far. At present state to casting die manufacturer for, have practice experience, knowing a mould to create the project technology staff that knows foundry technology again already also is lacked very much, and the mould is debugged and craft test and verify is a bank that strides surely in mould production process, because get successful mould and mature technology,be current a lot of technology force are weaker cast plant institute to hope. The application of the standardization of the mould and mould standard component will be henceforth the inevitable tendency that mould industry grows. This later to starting aluminium alloy gravity is cast is such more. Carried out a mould to standardize only, the behavior of manufactory of ability standard mould, make mould factory offer cheap of qualitative actor price the mould of up to standard ability is possible. In the meantime, the standardization of the mould reachs the application of mould standard component, will make cast a factory more easily monitoring mould quality, also make the maintenance of the mould is mixed maintain more convenience. The use of mould standard component, effect of scale of production will conduce to a change mould trade is current much breed, small lot, produce the condition with low efficiency, be helpful for reducing cost, improve productivity. Anyhow, size is exact, manufacturing efficiency is tall, facilitate use and be being safeguarded is mould industry is mixed cast an industry forever pursuit. CNC Milling CNC Machining
