Description
Technical field
The utility model relates to the process equipment of plastic packaging containers, specifically a kind of mold mechanism that is used on the plastic container forming machine.
Background technology
Existing automatic plastic container forming machine is provided with two groups of air cylinder driven mechanisms at least, approaching in opposite directions in order to the template and the bed die that promote symmetry so that its matched moulds, and the die cavity that defaults in each template inside that utilizes the matched moulds sheet to form, the bottle base of preheating is extended be deformed into the plastic containers of reservation shape.There is following shortcoming in the mold mechanism of such machine: two groups of above driving mechanisms are arranged, and energy resource consumption and machine take up room bigger; Each is driven symmetrical template in the set of molds (being generally two left and right mobile templates) by independent driving mechanisms, so its matched moulds position produces deviation unavoidably, influences closing precision.In addition, move left and right is carried out in also need being provided with in order to drive with symmetrical template synchronous of having, and can make himself upper and lower mobile bed die driving mechanism, so that with symmetrical template matched moulds, this must increase member again, and consumes energy has increased machine cost and occupation space.
The utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is to overcome the defective that above-mentioned prior art exists, provide one group of drive mechanism template synchronous of a kind of usefulness equidistantly to move, drive again simultaneously the mold mechanism of the synchronization-moving plastic container forming machine of bed die, by optimizing product structure, improve the matched moulds accuracy, reduce cost and energy consumption.
The technical scheme that the utility model adopted is as follows: the mold mechanism of plastic container forming machine, comprise pedestal, left template, right template, end template, drive plate and driving mechanism, and it is characterized in that:
Be provided with the transverse link that can on pedestal, move on the pedestal, the affixed right template of described transverse link right-hand member, the affixed drive plate of left end, loose joint left side template in the middle of it; Described driving mechanism is installed on the drive plate and with left template and is connected; Described end template is located at top, left-right template matched moulds interface by the interlock plate that is connected on the left template.
Right template of the present utility model and drive plate are fixed on the transverse link two ends, and the two is synchronous interaction in the same way, and drive plate is connected with left template by driving mechanism again, and the two can equidistantly synchronously move in the other direction.Such matching relationship, when drive mechanism left side template is moved right, self is moved to the left drive plate synchronously, the right template that links simultaneously with it also is moved to the left thereupon synchronously, thereby making left and right template is equidistantly to move in opposite directions synchronously, realize the left and right template mobile relation of mirror image each other, effectively guaranteed the matched moulds accuracy.End template moves (herein mobile be to move up and down) by interlock plate and left template synchronous.The interlock plate also can be arranged on right template, equally can reach synchronization-moving effect.Be moved to the left when resetting when driving mechanism spurs left template, other template also resets thereupon.The utility model is only used a driving mechanism, compares with two above driving mechanisms of existing structure, and more optimized structure, shared space is little, less energy consumption.
The mold mechanism of described plastic container forming machine, an affixed riser on the pedestal is connected a device synchronously between drive plate and the left template, and this sychronisation is fixed on the described riser.Sychronisation can be positioned at the front or the reverse side of riser, also can be positioned at going up or the lower end of drive plate and left template.Set up sychronisation and can guarantee accurately matched moulds or the die sinking simultaneously of left and right template, the plastic containers of blowing when avoiding die sinking be adhered to wherein on the template or by Form board tape from the bottle base supporting base.
