Description
[technical field]
The utility model is relevant with the folding mode structure of bottle blowing machine, particularly moves the folding mould device of accurate blow molding machine relevant for a kind of simple in structure and folding mould.
[background technology]
General common plastic containers such as bottle mostly are made in molded mode.And the so-called molded die cavity that blank is placed two corresponding half modules that is meant; make two half modules involutory mutually (matched moulds) by clasp mould mechanism then; allowing blank change compacted under at temperature, pressure etc. is and the corresponding product of die cavity shape, then opens two half modules (die sinking) by clasp mould mechanism again and take out the product that molding is finished.
Finish because the molded common need of blank change by pressure, and this pressure can produce the active force that backs down two half modules, therefore aforesaid clasp mould mechanism also can have the effect of mold closing or locked mode usually concurrently.
As No. 381539 " closing unit of hollow forming mould " novel patent of TaiWan, China patent announcement promptly is an example; it has two fixing die holders; fixedly establish between the die holder and some guide rods two; and on these guide rods, slide two slip die holders are set; then be equiped with two side form pieces between the two slip die holders; and fixedly installing blocking device between die holder and the slip die holder; blocking device has the toggle device and reaches in order to drive the drive unit of this toggle device; this drive unit can be pneumatic cylinder or oil hydraulic cylinder, makes this two side forms piece mold closing or die sinking to drive this slip die holder.
Above-mentioned closing unit is to use pneumatic cylinder or oil hydraulic cylinder as power source, is that movement response is very fast with pneumatic cylinder or oil hydraulic cylinder as the benefit of power resources, but exist following point also: at first, the action location of pneumatic cylinder or oil hydraulic cylinder is more inaccurate, and supervene vibrations easily, the location can not influence the matched moulds effect really, and then is easy to generate defective products; The vibrations of folding mould then may influence the accuracy of relevant action in the molded process; Moreover, use pneumatic cylinder or oil hydraulic cylinder that pressure pumping and reservoir vessel need be set in addition, this causes the waste of the energy easily.
In order to improve these problems, industry just uses the power source (as servomotor) of all electric to replace pneumatic cylinder or oil hydraulic cylinder, for example, M257273 number " drive unit that the control mould of plastic molding press opens and closes " novel patent of TaiWan, China patent announcement, it is to extend four guide rods by support, on each guide rod, place outer mould base and interior die holder, and a side of board is provided with a servomotor, servomotor drives a driving screw via time rule belt group, driving screw and one moves seat and screws togather, and mobile seat and support, then connect between interior die holder, can control the keying of sliding seats in-migration control mould by the control servomotor with several connecting rods.
Aforesaid " drive unit that the control mould of plastic molding press opens and closes " novel patent by by servomotor via the time rule belts group drive driving screw and control the structural design that mould opens and closes, really the effect of accurate control folding mould position can be reached, nor unnecessary vibrations can be produced.But servomotor can produce sizable speed reducing ratio via the kind of drive that time rule belt group drives driving screw, this can make the action of folding mould become slower, though and use driving screw to have the accurate advantage in location, but this is relatively poor in the tolerance level that bears axially loaded for driving screw, and this can relatedly make the variation in service life of driving screw.
To produce the blow-moulding machine of plastic containers, the number of times of present technology per minute folding mould may be up to 15～20 times, in other words, from inserting blank, matched moulds, the time that blow molding is taken out goods to die sinking had only for 3～4 seconds approximately, therefore concerning being blow molded into machine, open, the time of matched moulds all must finish in less than 1 second time, aforementionedly drive driving screw with servomotor via time rule belt group and control the structure that mould opens and closes, the speed of its folding mould is difficult to meet the user demand of blow molding machine, therefore for blow molding machine, the drive unit that aforesaid mould opens and closes has necessity of being improved again in fact.
To this, there is the dealer to develop the mechanism of folding mould fast and accurately again, as the novel patent announcement of TaiWan, China M333294 number " folding mould device of blow molding machine ", it is that two pedestals are set on blow molding machine, and between two pedestals, slide and establish two sliding seat, be respectively equipped with a half module between sliding seat and another sliding seat, and be provided with a linkage between sliding seat and the corresponding pedestal, and linkage is driven by a driving mechanism, driving mechanism is then by servomotor interlock one spiral arm, come the interlock linkage via a connection rod set again, and can carry out the action of folding mould quickly and accurately.
Yet, in aforesaid all kinds of patents, all only disclose the folding mould device of two half modules of folding, but bottle for blow molding, its mould normally cooperates a bed die to be formed by two half modules, aforesaid all kinds of patents technology all only discloses the technology of two half modules of folding, part as for bed die is normally driven by other gas/oil hydraulic cylinder, so design not only can't reach the requirement of all electric, and be difficult for carrying out synchronously by the action of two half modules of bed die that gas/oil hydraulic cylinder drove and motorized motions, and can influence start time of whole folding mould device, and then can have influence on the operating efficiency of blow molding machine.
