Die casting die, low pressure casting mould, gravity casting mould castings variety range, the quality of high and technological innovation highlights are beyond the previous, reflects the our country in recent years cast mould manufacturing toward large-scale, complexity, pay attention to the rationality of the structure design and humanized development trend. Each enterprise follows the new trend of foreign counterparts, China and foreign advanced to shorten the gap between industrialized nations. Among them, as the largest commodity casting mould manufacturing base - ningbo beilun district and xiangshan region has the largest number of exhibitors, showing the "Chinese die casting die township" and "China casting mould" hometown of powerful advantages and strength。

　　Casting mould large-scale tendency obvious. Along with our country die-casting industry large-tonnage casting a rapidly growing number of large-scale die-casting die more urgent need, the corresponding mould cannot domestic products has prevented the synchronous development of die casting industry. In recent years many mold enterprise by technical innovation and bought a large processing and heat treatment equipment, design and manufacture level increases, this kind of situation preliminary eased. Such as ningbo beilun huiwang mold industry co., ltd on display mode heavy 53 tons of "automobile engine V6 cylinder die-casting molds, ningbo become the mechanical mould co., ltd and ningbo beilun huiwang mold industry co., ltd of mold weighs 50 tons of" engine transmission between shell "die-casting molds, are installed in 38000N ~ 40000N large-scale die-casting machine is used on super large-scale die-casting die. Mode focuses on 20 ~ 30 tons, like car auto gearbox shell, automobile cylinders, elevator pedal, large trucks gearbox, etc, but also in many die-casting molds solo exhibition platform. In addition, appear in hangzhou close made machinery co., ltd exhibition of" 4114 cylinder mould "production is big iron diesel cylinder, the product is big and complex shape. Shows that our in manufacturing scale casting mould ability and level had great progress, large casting mould localization rate has been increased。

　　Casting mould manufacturing complex, enhance more and more difficult. Because of casting lightweight requirement and added functions, causing casting shape increasingly complex, dimension accuracy and the internal and external quality requirements also becomes strictly, for mould making put forward higher request. In the mould exhibition several subtropical high level mould conspicuous. Such as guangzhou cavity mould manufacturing co., ltd. Of heavy-duty trucks cummins engine parts "big gear room die-casting die", mould parts assembled by 24 thousand and become, periphery have 5 oil cylinder smoked pull the slider, using three square guide pin orientation, four pure positioning element positioning, ensure the casting precision. To meet the quality requirements, die-casting products internal processes adopted vacuum die-casting and inside mould Settings extrusion pin technology. Adopt refers to form flow design scheme, make the liquid metal village populated, they can better control the flow of liquid metal, flow and velocity, improve the product quality. Mould using large living block auxiliary forming, reasonable design of complex temperature control system, arranged 40 cooling route, 25 manifold, temperature control component parts of more than 800, At the same time in the mold to decorate temperature monitoring 21, external temperature digital display, according to the real-time monitoring temperature of feedback, in casting control terminals input parameters and realize the cooldown of start-stop and length of procedure control, so as to ensure mold work good temperature control ability. Ningbo xinda mould manufacturing co., ltd. "X90 redirector shell" die casting die, the product is pushed to form a number of different to smoke, request a mold pulling need two cavities, this company is very good solution to the parting selection, thin swimmers whose core cooling and repositioning problems, such as the produced series of steering gear housing die-casting molds, and many sets of exports to Europe. Ningbo resultant force casting mould technology co., ltd transportation "1.8t motor cylinder mould" used for the production of guangzhou automobile group 1.8 TS the automobile engine cylinder, using variable cross-section gating system, die structure used on the special-shaped core supports, special core head structure, solve hotbox thin-walled water jacket in casting process, is a set of the deformation of the domestic independent brand automobile development contribute to the success of the casting mould. Ningbo shing skill machinery co., ltd. Show "rack shell", "shifting box" die casting, reflects the company mold manufacture process attention to detail, exquisite workmanship, dimension accuracy, high profile clear handsome appearance。

　　V type cylinder large-scale die-casting molds car come out. As a manufacturing auto "heart" - engine cylinder die-casting molds, its r&d and manufacturing extremely hard, technical content is extremely high, product technical quality indicators extremely strict, has been die-casting die manufacturers committed to conquer problem. Thedefending mould exhibition "automobile in-line four cylinder pressure molding" appeared for the first time, in the industry has caused the attention, after two years, the domestic existing 7 ~ 8 manufacturer can be made. The ningbo beilun huiwang mold industry limited company of the exhibition "automobile engine V6 cylinder die-casting molds," once again in industry contry. The mould is domestic first developed V type cylinder die-casting molds, in foreign production had similar mould manufacturer also are few in number. This 530mm x x 360mm 300mm casting mould shape, size (1935mm x x 1850mm 1690mm), mould weighed as 53T, machining and assembling large difficulty, the product shape characteristics, needed more slider number, casting and higher density and die casting yield requirements of large, complex and difficult die-casting die. The mould adopts the bilateral feeding the runner, each are big the slider adopted dual cylinder smoke dial, special slider friction pair and after positioning structure, which can guarantee the smooth and reliable operation. Due to heavy heat capacity is big, casting mould work temperature balance condition is poor, therefore it must be passed various measures to strengthen the mold working temperature control。

　　Technical progress promoted industry overall level. The application of CAE already from past only get your orders needs to return to exert its function of practical technology, from the customer request to become an indispensable design personnel auxiliary tool. Many of the enterprise has also established this enterprise the mold base structure atlas, standard atlas, casting machine type atlas, casting process parameters, such as databases, convenient engineers in the design of typical cases and choose when using parameterization methods for implementing the resources sharing and shorten the design cycle. In addition, the enterprise in the process of mould when more consideration from "can create" transition to "can do", "superior quality" idea enhancement, attention prolong service life, ensure reliability and stability, improve production efficiency choiceness and finished product. Attention to mould runtime parameters of monitoring, feedback and automatic adjustment, to make mould more humane and intelligent. For technology and structural invention and innovation, enterprise declared national patent enthusiastic, awareness of ipr protection increase apparently.
