(2) Talented person serious insufficient, the scientific research development and the technical attack investment too urine mold profession is the technology, the fund, the work crowded industry, along with the time progress and the technical development, grasps the talented person which and skilled utilizes the new technology exceptionally short, the highquality mold fitter and the enterprise management talent extremely is also anxious. Because the mold enterprise benefit unsatisfactory and takes insufficiently the scientific research development and the technical attack, the scientific research unit and the universities, colleges and institutes eye stares at is creating ine, causes the mold profession invests too few 9 in the scientific research development and the technical attack aspect, causes the mold technological development step doe not to be big, progresses does not be quick. (3) The craft equipment level is low, also is not good, the using factor is low. Recent years ,our country engine bed profession progressed quickly, has been able to provide the quite plete precision work equipment, but pared with the overseas equipment, still had a bigger disparity. Although the domestic many enterprises have introduced many overseas advanced equipment, but the overall equipment level low are very more than the overseas many enterprises. As a result of aspect the and so on system and fund reason, introduces the equipment not necessary, the equipment and the appendix not necessary phenomenon are extremely mon, the equipment utilization rate low question cannot obtain the paratively properly solution for a long time . (4) Specialization, standardization, mercialized degree low, the cooperation ability Because receives large and plete small and entire the influence since long ago, mold specialization level low, the specialized labor division is not careful, the mercialized degree is low. At present domestic every year produces mold, modity mold minister 40% about, other for from produce uses for oneself. Between the molds enterprise cooperates impeded, pletes the paratively largescale mold plete task with difficulty. Mold standardization level low, mold standard letter use cave rare is low also to the mold quality, the cost has a more tremendous influence, specially has very tremendous influence. Modern fast economy manufacture mold technology Along with the global economy development, the new technological revolution made the new progress and the breakthrough unceasingly, the technical leap development already bees the important attribute which the impetus world economics grew. The market economy unceasing development, urges the industry product more and more to the multi varieties, high grade, the low cost direction to develop, in order to maintain and strengthens the product in market petitive power, product development cycle, production cycle more and more short, thereupon to makes each kind of product the essential craft equipment mold request to be more and more harsh. On the one hand the enterprise for the pursue scale benefit, causes the mold to turn towards high speed, is precise, the long life direction develops。 On the other hand enterprise in order to satisfy the multi 10 varieties, the product renewal quickly, wins the market the need, requests the mold to turn towards the manufacture cycle to be short, the cost low fast economy direction develops. The puter, the laser, electronic, the new material, the new technical development, causes the fast economical pattern making technology even more powerful, the application scope expands unceasingly, the type increases unceasingly, the creation economic efficiency and the social efficiency are more and more remarkable. The fast economical pattern making technology and the traditional machinefinishing pares, has the pattern making cycle short, the cost is low, the precision and the life can satisfy in the production the operation requirements, is synthesizes an economic efficiency quite remarkable kind to make the mold the technology, summarizes below, has several types to leave. 1 fast prototypes manufactures technology The fast prototype manufacture technology is called RPM, is one kind of new manufacture technology which the 8039。s later period develops. US, Japan, England, Israel, Germany, China have all promoted own mercialization product, and has formed the new industry is the puter, the laser, the optical scanning, the advanced new material, the puteraided design (CAD), the puter assistance processing (CAM), the numerical control (CNC) synthesizes the application the high technology and new technology. In takes shape in the concept take the plane separate, piles up as the instruction, in the control take the puter and the numerical control as the foundation, take biggest flexibility as general goals. It has abandoned the traditional machinefinishing method, to the manufacturing industry transformation is a significant breakthrough, uses the RPM technology to be possible directly or indirectly the fast pattern making, this technology already by profession widespread application and so on automobile, aviation, electrical appliances, ships, medical service, mold. 2 surfaces take shape the pattern making technology The surface takes shape the pattern making technology, mainly is the use spurts spreads, the electrolytic casting, chemistry corrosion and so on the new technique formation cavity surface and the fine pattern one kind of craft technology, in the practical application including following several kind of types. electric a
