Description
Technical field
The present invention relates to blow mould, be specially the folding mould driving mechanism of blowing mould.
Background technology
As illustrated in fig. 1 and 2, existing blowing mould mainly include matched moulds header board 1 ', plate 2 in matched moulds ' and matched moulds after plate 3 ', three is set up in parallel according to the order of sequence and can slides along track, work in-process, for realizing normal folding mould processing, must guarantee matched moulds header board 1 ' and matched moulds in plate 2 ' by sealing cylinder 4 ' centered by, the opposite direction of both motions, distance is identical with velocity magnitude.
In existing blowing mould, matched moulds header board 1 ' and matched moulds in plate 2 ' folding mould driving mechanism adopt rack-and-pinion lazy-tongs, it comprise one be arranged on plate 2 in matched moulds ' and matched moulds after plate 3 ' centre driving gear 51 ', driving gear 51 ' top be connected with a joggle with matched moulds in plate 2 ' be connected upper rack 52 ', driving gear 51 ' bottom be connected with a joggle with matched moulds after the lower tooth bar 53 that is connected of plate 3 ', plate 3 after matched moulds simultaneously ' and matched moulds header board 1 by main shaft 6 ' be fixed together.
When die sinking, driving gear 51 ' clockwise rotate, due to the engagement fit motion of rack-and-pinion, upper rack 52 ' by plate 2 in drive matched moulds ' synchronously move to right, lower tooth bar 53 ' by plate 3 after drive matched moulds ' synchronously move to left, plate 2 in matched moulds ' and matched moulds after plate 3 ' between distance reduce, and plate 2 in matched moulds ' identical to the distance of the distance of driving gear 51 ' minimizings and plate after matched moulds 3 ' arrive driving gear 51 ' minimizing, simultaneously due to plate after matched moulds 3 ' and matched moulds header board 1 ' by main shaft 6 ' be fixed together, plate 3 after matched moulds ' move to left drive matched moulds header board 1 ' synchronously move to left, thereby make matched moulds header board 1 ', the relative sealing cylinder 4 ' counter motion in the ground of plate 2 ' synchronous same-speed in matched moulds and realize die sinking.In like manner, when matched moulds, driving gear 51 ' rotate counterclockwise, due to the engagement fit motion of rack-and-pinion, upper rack 52 ' by plate 2 in drive matched moulds ' synchronously move to left, lower tooth bar 53 ' by plate 3 after drive matched moulds ' synchronously move to right, plate 2 in matched moulds ' and matched moulds after plate 3 ' between distance increase, and then make matched moulds header board 1 ' and matched moulds in plate 2 ' carry out move toward one another, and both displacement is identical with translational speed size.
The synchronous drive mechanism coordinating in above rack-and-pinion, although also can realize matched moulds header board 1 ' and matched moulds in plate 2 ' folding modulo operation, but because of the direct contact squeeze of engaging tooth in the engaged transmission of rack-and-pinion, have that wearing and tearing are large, tooth bar easy fracture, noise is loud, difficulty of processing is high, rack-and-pinion has the defects such as gear clearance.
And topmost shortcoming is to install to regulate inconvenience, when installation mold, because causing mould, mismachining tolerance there is thickness, for guaranteeing to open closing precision, need to adjust header board 1 ' and middle plate 2 ' to the distance at sealing cylinder 4 ' center, in this process, need be by driving gear 51 ' taking-up, promote whole matched moulds frame, first will be apart from adjusting, then rotate rack fixing seat, by upper and lower tooth bar 52 ', 53 ' position adjust suitable, finally load onto driving gear 51 ', whole installation process bothers very much, gives actual use and late maintaining has brought very big inconvenience.
Summary of the invention
