Description
Technical field
The utility model belongs to the plastic molding machine technical field, is specifically related to a kind of opening and closing mold mechanism.
Background technology
China utility model patent Granted publication CN2481511Y discloses a kind of clasp mould mechanism and Granted publication CN2481510Y has recommended opening of a kind of architecture advances; clamping; last patent has overcome the two places shortcoming that utility model patent ZL95246435.7 (the middle-size and small-size clamping of blow moulding machine) exists (specifically can referring to the explanation of specification the 1st page of the 4th to 17 row of CN2481511Y); concrete scheme is horizontally-arranged on towing plate by the middle part of Mode-locking oil cylinder; that is to say; make an end of Mode-locking oil cylinder be positioned at a side of towing plate; the other end then is positioned at the opposite side of towing plate; to ride the length that positive effect that mode is provided with Mode-locking oil cylinder can shorten guide rod and connecting rod; make the volume of blow molding machine realize miniaturization, and reduce manufacturing cost and save material.Back one patent has overcome the existing drawback of utility model patent ZL95246446.2 (the big-and-middle-sized clamping of blow moulding machine); specifically can be referring to the 1st page of the 4th to 22 row of specification of CN2181510Y; positive effect is both to help dwindling the blow moulding machine overall volume, avoids the guide rod distortion; help avoid when the opening and closing mould left and right mould bases again and take the phenomenon that left and right half module rocks, make opening and closing imitate fruit and is guaranteed (Instructions Page 2 the 1st to the 7th of seeing CN2481510Y is capable).
Above-mentioned two patent schemes structurally have something in common; promptly except outfit is used to draw the synchronous movement device (rack-and-pinion sychronisation) that left and right mould bases closes up each other or scold out; also need be equipped with the opening and closing mould oil cylinder; as power source, and synchronous movement device is as follower by the opening and closing mould oil cylinder.Therefore there is common shortcoming: one, because synchronous movement device self does not have power, the work whether motion of synchronous movement device depends on the opening and closing mould oil cylinder whether, yet, because the movement travel of opening and closing mould oil cylinder is the cylinder post stretches outside cylinder body or there is the error that can not eliminate between the two in the movement degree of the distance that bounces back and synchronous movement device, therefore can influence the precision of opening and closing mould, especially when matched moulds, because of the wing limit can appear in matched moulds effect shortcoming on plastic products, influence the quality of product even cause product rejection; Its two, the required oil mass of opening and closing mould oil cylinder is big, is unfavorable for energy-conservationly, and because of opening and closing mould oil cylinder own vol is big, is unfavorable for realizing the complete machine miniaturization of plastic product molding machine.
In view of this, the applicant thinks that the opening and closing mechanism in the prior art still has improved necessity, and technical scheme described below forms under this background.
