Summary: The orgnaization that smoke core has very important place in plastic mould, matter to the produces efficiency and product price of the mould directly. The article with steady flow 3 types mould is an introduction orgnaization of a kind of new-style fast drawing of patterns, analysed the orgnaization of drawing of patterns of the thread plug of similar pattern, the difficulty of drawing of patterns of mid to its cent undertook an analysis, had a few introductions to process of drawing of patterns. Keyword: 3 moulds; Fast drawing of patterns; The development of thread plug preface as new-style and plastic material, craft, plastic product with its weight the characteristic with good, low cost gained light, strength wider and wider application. In section water domain, a main product -- steady flow 3, with its cost is low, the effect is apparent, leave out multistage silt filter wait for an advantage and by wide application, but this kind of product because goods structure is special, the produces speed to wait for a characteristic slow to bring about this kind of product production rate of the mould rises not to rise from beginning to end, the section water that creates partial district irrigates the mode that device is in the past from beginning to end. 1 goods analysis is plastic steady flow uses PE raw material 3 times, compare on the structure special, if the graph is shown 1 times, through the analysis, this kind of goods can choose cent side the median plane that in goods two axes place fixes to go up only, and use symmetrical type flow path, one model two antrum. Whorl allows legibility quite outside definitely, can divide directly model get, of direct part model core drawing of patterns is OK also by method of traditional inclined guide pillar fast drawing of patterns, the key depends on goods the 3rd inside the design of drawing of patterns of whorl part, of this goods inside whorl pitch is 2mm, altogether should rotate 42.

5/2=21.

25. Ability general core is complete emergence goods. Graph 1 goods pursues on the drawing of patterns that difficulty of 2 moulds design and the difficulty of drawing of patterns that analyse this goods depend on the 3rd, l1=(42 of the length after the whorl of M22 spreads out.

5/2) × 3.

14x22=1466mm, if use drawing of patterns of means of gear rack drawing of patterns, open modular space effectively considering what record model machine, the length of rack can accomplish 300mm at most, accordingly transmission comparing should choose 5:1, want to obtain so big drive to compare, the bulk certainly will of the mould is very old, accordingly, this kind of traditional pattern chooses the design of mobile mold insert normally, use artificial method to come back mobile mold insert. If the graph is shown 2 times, mobile mold insert and product are connected one case after flying a model the top goes out, the pattern puts mobile mold insert after manual drawing of patterns next, undertake noting model procedure the next time. Graph the uses mobile mold insert method of 2 traditions 3 fast, full automatic the innovation of drawing of patterns designs the characteristic according to this goods, discovery wants emergence only part of this goods whorl next again direct will model core is taken out can realize drawing of patterns, this whorl pitch is 1.

5mm, so need general core rotates circle of 8 ÷ 2=4, be not pulled to assure whorl wool, will model core rotates pen number is surely 4.

5. Use two class transmission, modulus chooses 1mm, gear 3 with gear 2 drive are compared is 2:1, gear 2 with gear one drive compares 3:2Systematic drive is compared for 3:1, 3 tine number is gear 30 tine, the tine number of one is gear 30 tine, because this rack ages,number is 45 tine. If the graph is shown 3 times, 4 rack are secured in fixed die on, 1/3 is two coaxial gear, when flying a model, all gear are clench the teeth, gear turns on rack, drive thereby 4 model core gear axis turns with the speed of 3 times, when model the whorl part of core gear is complete from the emergence on goods, install two cant on rack to just contact slide block, and gear of slide block core along with all the others emergence goods, if the graph is shown 4 times, in the graph 4 be model core gear axis, 2 for brass nut, pitch and make pitch is same, so, as model the roll of core gear axis, model core will be automatic from the emergence in goods, and won't hurt the whorl share that reachs goods. 1- gear gear of 3- of one 2- rack 2 4- gear slide block of 6- of 3 5- slide block 2 graphs gear of 4- of slide block of 3- of brass nut of 2- of silk of top of 1- of 3 innovation design 3 graphs 4 conclusion draw sketch map of 4 campaign process the difficulty that core orgnaization is mould design and key, of mould production be particular about is efficient, high quality, the process of tall automation, afore-mentioned 3 are to compare a typical kind to be made hollowly, its volume is average 3 are an organic whole with thread plug of inside and outside, and, whorl smokes core longer, the gear rack that uses a convention or orgnaization of oil cylinder rack comes true very hard, practice proves afore-mentioned design method drawing of patterns are successful, manufacturing efficiency rises considerably, realized the design requirement of expect, obtained very good economic benefits, mould life can amount to above 500 thousand times. The mould design with above design congener to other method has fair referenced value. CNC Milling
