Description
Technical field
The present invention relates to blowing mold, be specially the folding mould driving mechanism of blowing mold.
Background technology
As illustrated in fig. 1 and 2, existing blowing mold to mainly include in matched moulds header board 1 ', matched moulds plate 3 ' after plate 2 ' and matched moulds, three is set up in parallel according to the order of sequence and can slides along track, work in-process, for the processing of normal folding mould can be realized, must ensure that in matched moulds header board 1 ' and matched moulds, plate 2 ' is centered by sealing cylinder 4 ', the direction of both motions is contrary, and distance is identical with velocity magnitude.
In existing blowing mold, matched moulds header board 1 ' adopts rack-and-pinion lazy-tongs with the folding mould driving mechanism of plate 2 ' in matched moulds, it comprises one and is arranged on the middle driving gear 51 ' of plate 3 ' after plate in matched moulds 2 ' and matched moulds, driving gear 51 ' top is connected with a joggle the upper rack 52 ' be connected with plate in matched moulds 2 ', driving gear 51 ' bottom be connected with a joggle with matched moulds after the lower tooth bar 53 ' that is connected of plate 3, after matched moulds, plate 3 ' and matched moulds header board 1 are fixed together by main shaft 6 ' simultaneously.
When die sinking, driving gear 51 ' rotates clockwise, because the engagement fit of rack-and-pinion is moved, plate 2 ' in drive matched moulds synchronously moves to right by upper rack 52 ', plate 3 ' after drive matched moulds synchronously moves to left by lower tooth bar 53 ', in matched moulds, after plate 2 ' and matched moulds, the spacing of plate 3 ' reduces, and the distance that after the Distance geometry matched moulds that in matched moulds, plate 2 ' reduces to driving gear 51 ', plate 3 ' reduces to driving gear 51 ' is identical, simultaneously because plate after matched moulds 3 ' and matched moulds header board 1 ' are fixed together by main shaft 6 ', after matched moulds, drive matched moulds header board 1 ' synchronously moves to left by moving to left of plate 3 ', thus make matched moulds header board 1 ', in matched moulds plate 2 ' synchronous same-speed ground relative sealing cylinder 4 ' counter motion and realize die sinking.In like manner, when matched moulds, driving gear 51 ' rotates counterclockwise, because the engagement fit of rack-and-pinion is moved, plate 2 ' in drive matched moulds synchronously moves to left by upper rack 52 ', and plate 3 ' after drive matched moulds synchronously moves to right by lower tooth bar 53 ', and in matched moulds, after plate 2 ' and matched moulds, the spacing of plate 3 ' increases, and then make plate 2 ' in matched moulds header board 1 ' and matched moulds carry out move toward one another, and both displacement is identical with translational speed size.
At the synchronous drive mechanism that above rack-and-pinion coordinates, although the folding modulo operation of plate 2 ' in matched moulds header board 1 ' and matched moulds also can be realized, but because of the direct contact squeeze of engaging tooth in the engaged transmission of rack-and-pinion, existence wearing and tearing are large, tooth bar easy fracture, noise are loud, difficulty of processing is high, rack-and-pinion has the defects such as gear clearance.
And topmost shortcoming installs to regulate inconvenience, when installation mold, because mismachining tolerance causes mould to there is thickness, for ensureing to open closing precision, header board 1 ' and the distance of middle plate 2 ' to sealing cylinder 4 ' center need be adjusted, in the process, driving gear 51 ' need be taken out, promote whole matched moulds frame, first distance is adjusted, then rotate rack fixing seat, by suitable for the adjustment of the position of upper and lower tooth bar 52 ', 53 ', finally load onto driving gear 51 ', whole installation process bothers very much, brings very big inconvenience to actual use and late maintaining.
Summary of the invention
