1、The application of mouldAccording to the demarcation of the Chinese molding tool industry association, the our country molding tool is basic to is divided into the 10 major type, among them, hurtling to press the mold and plastics to model the mold two major type to have the main part. Press the pro
2、duction value calculation, the our country hurtles to press the mold to have 50% currently or so, the plastics takes shape the mold to about have 20%, pulling the silk mold (tool) to about have 10%, but in the world flourishing industrial country and the plastics of the regions take shape the mold c
3、omparison to have all 40%s of molding tool production value generally above.The country molding tool industry the technique level is not even currently, hanging to compare extremely greatly. From total come up to speak, compare with advanced level of flourishing industrial country and the harbor mes
4、a areas, still have the bigger margin. In the aspects of adopting CAD/ CAM/ CAE/ CAPP etc. Technique design and the manufacturing molding tool, is an applied extensive regardless, still the technique level up all exist the very big margin. At the applied CAD technique design molding tool aspect, had
5、 only to adopt the CAD in the design about 10% molding tool, be apart from to lay aside to paint the plank to still is endless of a segment road want to walk; Carry on the molding tool project design and analysiss to compute the aspect in the applied CAE, also just just start, still was placed in to
6、 try out mostly and animation game stage; At the applied CAM technique manufacturing molding tool aspect, on is a manufacturing material that lacks the forerunner to apply, two is an existing craft equipments( include the advanced equipments that near more than 10 in the last years usher in) or beca
7、use of computing the mechanism type( tiny machine of IBM and it and permit the machine, the HP work station.etc.) dissimilarity, or because of the word stanza difference, operate the speed difference, the anti- electromagnetism interference ability difference.etc., the net rate is lower, only 5% or
8、so molding tool manufacturing equipments just opens this work of exhibition in recent years; Carry on the craft programming aspect in the applied technique of CAPP, be placed in the blank appearance basically, need to be carry on to standardize the foundation work in great quantities; At the molding
9、 tool total sex craft technique, if the molding tool models the technique, throws the light technique and gives or get an electric shock to cast into a technique, surface processing technique CAD/ CAM technique application of etc. quickly is just at the our country just start. The calculator lends s
10、upport to the technical software development, being placed in the lower level, the demand knowledge and empirical backlog still. The molding tool of big and parts of molding tool factories of our country, the car processes the equipments old, expect to be long in the service, the accuracy is bad, th
11、e efficiency is low, using up to now and still common of car, plane, drill, whet the equipments to process the molding tool, the hot processing processes to use the salt bath, a type stove still, operation with the workers experience, the equipments is simple and crude, can consume high. The equipme
12、nts renews the speed slow-moving, technique reformation, technique progress the strength is not big. Although also ushered in the molding tool of not a few forerunners to process the equipments in recent years, scatter too, or unqualified set, the utilization has or so 25% generally and only, some a
13、dvanced functions of the equipments also can not get full exertive. Lack the higher molding tool design, the manufacturing craft of the technique character technical personnel and technique worker, lack a talented person of a breadth of knowledge, the knowledge structure layer particularly. Technica
14、l personnel within Chinese molding tool profession, have 8% of the employee only 12% is or so and the total technique level of the technical personnel and technique worker are also lower. Was aging with the technique workers knowledge from the technical personnel of the industry before in 1980, the
15、knowledge structure cant adapt the demand of now; But the 80s is from the personnel of the industry hereafter, the professional knowledge, experience is short of, beginning the ability bad, uneasy heart, do not wish to learn the technique. In recent years the brain drain not only results in talented
16、 person quantities ands the character levels descend, and talented persons structure but also appears to break the layer lately, temporary shortage, make the hard exaltation of technique level of the molding tool design, manufacturing.Near more than 10 in the last years, especially85, nation is already many to organize the relevant material graduate school, university and college and the steel business enterprises, research and development the molding tool appropr
