Abstract
A die carrier structure of a blow moulding machine includes a frame and a locking mechanism driven by a cylinder and provided on the frame. A group of cross support frame and an axle seat with a sliding bush which can support a pair of guide shafts are separately provided between a front template and a back template and between the back template and a pull plate in the front of the frame. The axle seat provided between the front template and the back template which can support the guide shaft is at the outer end of the front of the frame. The utility model uses the axle seat with the sliding bush separately provided between the front template and the back template and between the back template and the pull plate on the upper surface of the frame which can support a pair of guide shaft, in particular the axle seat supporting the guide shaft between the front template and the back template which is provided at the outer end of the upper surface of the frame, by which the structure of the pair of guide shafts is changed to a rigidity support structure from primary cantilever type structure, thus the die during the whole blow moulding process is stable and reliable, and the quality of the blow moulding product is guaranteed.

Technical field
The utility model relates to the mould bases structure of a kind of blow moulding machine, particularly a kind of blow moulding machine.
Background technology
The mould bases structure of existing blow moulding machine; mainly form by the open-and-close mechanism of the made front and back swooping template action that is installed on the front and back template that mould is housed on the frame and hydraulic pressure or pneumatic actuation; described open-and-close mechanism comprises that mainly one can make the gear of front and back template reciprocating action; the guide rod of template direction before and after tooth bar transmission and the realization; described guide rod is generally two; usually be arranged on template bottom, front and back and laterally run through the front and back template; for the realization of the opening and closing movement of guaranteeing template and take out workpiece easily and corresponding with blowing nozzle position; the relative frame of above-mentioned guide rod becomes the cantilevered setting; and the supporting-point of guide rod mainly the sliding bearing by guide rod rear end and towing plate and be arranged at rear pattern plate and towing plate between bearing block support; the weak point of this structure is; during matched moulds under the effect of blowing air pressure; template and guide rod produce the cantilever-type load of moment before and after can making; mould faying face before and after making on the template produces certain dislocation and gap; consequently cause blowing the thick and unshapeliness of assembly loft of plastic products; influence the quality of finished product; for overcoming above-mentioned existing problems; Chinese patent ZL95246435.7 discloses the middle-size and small-size clamping of a kind of blow moulding machine; one of its main technical points is for strengthening the rigidity of whole mould bases; set up a connecting rod in two guide rods bottom; though like this rigidity that improves mould bases is had certain effect; but because this connecting rod does not change its integral body with combining of bolster and guide rod still is a vacant state; therefore in use, still above-mentioned existing problems appear in the product that can occur blowing out.
Summary of the invention
The purpose of this utility model is that providing a kind of at above-mentioned existing problems strengthens the mould bases integral rigidity and its mould bases structure simple in structure, reliable blow moulding machine.
The technical solution of the utility model is: a kind of mould bases structure of blow moulding machine; comprise frame and be arranged on the frame clamping by air cylinder driven; before described clamping comprises; rear pattern plate; towing plate; the rack-and-pinion transmission; before a pair of the traversing; rear pattern plate; the connecting shaft that the guide shaft of towing plate and two ends link to each other with towing plate with front template respectively; be characterized in above-mentioned and reaching the axle bed that is respectively equipped with one group of cross bearing support axle bed between rear pattern plate and the towing plate and can supports the band sliding sleeve of a pair of guide shaft between frame upper surface front template and the rear pattern plate, the above-mentioned axle bed that is arranged at the supported guide shaft between front template and the rear pattern plate is positioned at the outer end of front on the frame.
The utility model is owing to adopted at the axle bed that reaches the band sliding sleeve that supports a pair of guide shaft that is provided with respectively between rear pattern plate and the towing plate between frame upper surface front template and the rear pattern plate, particularly the axle bed of the supported guide shaft between front template and the rear pattern plate is arranged at the outer end of frame upper surface, make a pair of guide shaft become a kind of rigid supporting structure by original cantilever structure, before and after when blow gas acts on mold cavity and produces downward instantaneous pressure template can by be arranged on that the supporting of axle bed on the guide shaft prevents to produce between solid model plate and guide shaft around the property strain, thereby make whole blowing process mold work stable, reliably, guaranteed the quality of blow molded product.
