1、 中文 2460 字 外文资料翻译 The Fresh Generation Injection Mould Technique 1、 Summary The indexing vase embryo mould plastics technique is designed the development at twin teeterboard machinerys of Huskys mould plastics system .Ought to systematically there be an all sides to stir the teeterboard to coil the
2、cross axle to circle.Each one section is matched somebody with somebody a type semi to cool to mold the standard .The master stamper systematically is 48 an overcast standard , thereby supplys 192 standard rushs pith .Fiing teeterboard jacket possess criterion heat flux a road and semi an overcast s
3、tandard .Standardized two steps of moulds plastics units are equipd to this system , and that unit possessone 120 millimeters to pack the engine molding and 120 millimeters to inject the pressure stuff to squeeze in , and injecting along the Great Wall the pressure stuff possess engine a thick tube-
4、shaped head and a distribution valve to join two grades .Designing in the way of the vase embryo at the moment , target weight is the 47.3 grams vase embryos , thereby injecting amount is 2270 grams .Two 42 differences is gatherd being used a system to the benzol two methanoic acid glycol ester stud
5、s , and every one wholly acquireed the effect that may be receiveed . When the machinery cycles , the plastic material first of all injects up A .Since the fact that the vase embryo will remain the standard rush pith on , the vase embryo is living to turn on guarantors pressure time the standard not
6、 necessaries , and that traditional system goes up such as being living is stiff in that way .Hence , the machinery cycle that the overwhelming majority cooling may be living soon afterwards perioc through shuts the standard revolves up to become cool on the rush pith at the standard .Afterwards the
7、 cycle needs an extraordinary brief cooling perioc in order to permit the pattern to elucidate the pressure , injects and defends and to be getting near also is such in this way .Afterwards the plastic material are living Bs surface is injected on this peak ministry face that the teeterboard was rea
8、chd in the indexing on one section when turning on the standard .As D before arrival when the extremity , now A is living teeterboard base place , and the push rod is switched on here , and the vase embryo is unloaded the finished piece through the machinery and leads to on the conveying utensil .In
9、jecting the stroke adjust the cycle time not effect , as a result may complete more slowly .Gravitational force help is guarranteed that the finished piece breaks away from that the pattern drops secondly .The finished piece drops such the curtain squares formed by crossed lines tip conveying utensi
10、l on , and the probability that creates the surperficial gall is littleer . A ministry is living 、 Gas dashing systematic twin vase embryo of forming supplys the face and becomes cool the place of back and base .Since the fact that the vase embryo maintains the pattern standard rush pith on , the fa
11、ce obtains the conduction cooling included they are still convenient .Says in the total , the entire temperature of vase embryo than it is living traditional compression molding system and cooling leads to in the plank to stay analogous time will cool . 2、 The Bottle Function Significant respect tha
12、t we analyse the indexing system analogous a of jar of vase that the embryo was manufacture out that to be the performance takeing this kind of vase that the vase embryo that the system was gived birth to was manufacture out against traditional work gived birth to on the cell one another contrasts .
13、The comparand that obtaines in the eperiment that the table 1 is give out through is underway is depenied on . The indexing vase embryo performance is living and is better always in the intensity quiz , and this is better distributing for the runner quality which improved permits the stuff to be liv
14、ing inner place the vase , and does not there is the indication to m with guarantor . make known that use this kind of system is living whatever space crystallinity of vase and ascendes .The indexing specimen gived birth to is probably equally light , for their weight distributions is to be much ins
15、eparable 3、 This kind of system distinguishing feature Inner place the standard that to support with the hand the obviousest advantage of earthen brick is needs the cooling time decreased , thereby decreased entire time length that cycles .At the moment , this kind of system employ the largesttest b
16、reastwork thickly act as 4 millimeters the 47.3 grams vase embryos do .This kind of vase embryo process cycle time ascertains by measuring to 22.5 seconds , was optimum as to the overcast standard system .Overcast standard system implementation 14.2 seconds of indexing 48 cycle be able to be acquire
17、ed the better trade quality killing .The picture 2 is give out the cycle subdivided comparing situation . Circling the control tower does not need the manipulator again .Like this , therefore decreased from the tradition system to go up the jam that the manipulator block created is giveed an alarm a
18、nd the service ceases engine time .The finished piece peak has ariseed to be living not to be the inflexible cycle time the element .Decreased in the standard the turning on gap that needs in the wake of removing the manipulator , in the wake of decreasing of pattern stroke still lift empties cycle
19、velocity . Systematic another advantage is the floor area that needs decreases , along with thanks to does not there is manipulator and lead-out plank cooling system , latent capacity that the dependability of system may be liftd .Calculate in advance entire systematic dependability that therefore t
20、he manipulator obstructs does not happen permit the systematic usability to lift 30% .Merely traditional 48 55% of overcast areas that the standard system requires of indexing system floor area .Against the person who one another accompanies the yield that still possess per foot of floor area lifts
21、further . Employ the indexing systematically to cause an a jar of embryo runner quality obtain the modification .Being living , the valve runner district is freezed afterwards , the vase embryo is living brieflyer time inner place the heatpoint contact against the valve staff , for the cooling that
22、the vase embryo is living inner place the overcast standard time by enormously decreases .Geing rid of this heat source removes a crystal source .Except for better vision effect , still causes that the runner district is more sturdy , thereby causes entire a of jar of side wall district better , and
23、 possess the weight that even more opportunitys ease the vase embryo in base district . The vase embryo to remain at the standard rush pith elderer time .Systematically being contrastd against a criterion a jar of embryo mould plastics , entire a of jar of embryo becomes cool obtainning the modifica
24、tion .Being living , tradition manipulator becomes cool inner place the plank , and the finished piece is encounter and be able to be shrinked by the tube face becoming cool , and such heat transfer is imconsummate .In being living the indexing system manufactures at the standard shrinking on the ru
25、sh pith , thereby maintain heat transfer , and is living when being come out , and will let drop when comprehensive entirety temperature of indexing vase embryo contrasts the a jar of embryo lead-out place through traditional system brings out by the peak .Still possesing , and designs as to the vas
26、e embryo at the moment , not to the throat standard ring district supply cooling water , being living , the peak when comeing out yet systematically will be cooled far more than the criterion .Become cool that district threshold energy system cycling as to the forming system of type . The distinct s
27、tuffs of indexing system in the way of some kinds reaches the difference of two kinds of distinct stuffs testing with two kinds to gather designing to the benzol two methanoic acid glycol ester studs , and may catch sight of that the acetaldehyde ( AA ) amount lets drop always .against injecting amo
28、unt is contrastd this cycle time adjust injects the unit proposes the very much tall demand , injects the unit constinuously scousrs not to there is a few is held up time the stud . Since the overcast standard of peak value inner place the pattern tallys with against the two differences studs , and
29、against the difference process installation unanimously , the acetaldehyde is measured ever to possess to let drop that the main reason rests with that the pattern gathers materials the tube more .Second advantage may catch sight of in the way of the pattern at the moment is possesing the very much
30、good weight distributions , thereby permits to be living at the moment finished piece standard allows bad inside entire finished piece weight to drop the thest least degree . 4 、 The injection mould design process requirementanalysis An injection mould design is composed of two steps: theinitial des
31、ign and the detailed design. The initial design iscomposed of decisions made at the early stage of themould design, such as the type of mould configuration,the number of cavities, the type of runner, the type of gate and the type of mould base. The detailed design iscomposed of the insert (core/cavi
32、ty) design, the ejectionsystem design, the cooling and venting component design,the assembly analysis and the final drafting. To develop a good CAIMDS, an analysis of whatthey have and what they want needs to be performed.What they have. The customers requirements for the product. Thisincludes the detailed geometry anddimension requirementsof the product. An existing mould design library. This library coversthe standard or previously designedcomponents andassemblies of the mould design, for example, themould base
