So, the utility model has compact and exact matched moulds without material spilling, and the service life of the mould is lengthened; the utility model has no effects to the material supplying and the output of the finished products, and increases the best efficiencies of the finished products.

Description

Mould closing member for blow-moulding shaper

The utility model is a kind of matched moulds member of blow molding machine, and be a kind of mold alignment, no flash, prolong die life, the matched moulds member of very big value arranged on industry.

In the prior art, the matched moulds member of traditional type is because of considering the space of shifting formwork, folder raw material and finished product output for clamping plate, so it contains two clamping plates 2 that have fixing hole 28 basically, and the slide-bar 22,23 of connection clamping plate and main frame wall 1, balancing pole 24, balance lever 26 and oil pressure axle 25, as shown in Figure 5.When this matched moulds member uses, exist many shortcomings on production line:

Mould 3 between two clamping plates 2 by slide-bar 22,23, after the action of balancing pole 24 and oil pressure axle 25 cooperates following matched moulds, the matched moulds compression that is produced is not on the central point of mould 3, thereby the build-up of pressure inequality, the phenomenon that causes finished product to have woolen cloth to overflow when matched moulds.

2. because under the uneven use situation of matched moulds compression, after using a period of time, because slide-bar 22,23 and slide-bar hole 211 produce friction for a long time, then caused the expansion in slide-bar hole 211, thereby make mould can't obtain matched moulds exactly, and woollen phenomenon of overflowing is more and more serious.

3. mainly lean on the pressure of oil hydraulic system because of the driving fit of mould, and the tension force that is produced usually causes the mould pine to open when blow molding pressurizes, thereby cause the not increase of good yield rate.

4. because of matched moulds is inaccurate for a long time, not just slide-bar hole 211 expansions of clamping plate that brought have also caused shorten greatly the service life of mould itself.

The purpose of this utility model is for solving above-mentioned existing shortcoming, design a kind of matched moulds member of novel blow molding machine, use this novel member can not only make tightly driving fit of mould, do not have woollen spillover and mold alignment, prolong die life, and best yield rate will increase greatly.

The matched moulds member of blow molding machine of the present utility model comprises: the clamping plate that has fixing hole 28 2 that places mould 3 two ends, by the slide-bar 22,23 that extends on the main frame wall 1 and link with clamping plate 2, balancing pole 24 and oil pressure axle 25, hook plate and shank sub-assembly 4, roll-setting gear 5 and oil hydraulic cylinder 6.Shown in accompanying drawing 1,2,3,4.

The key and the advantage thereof of this new type of component are:

1. after oil hydraulic system with two ends is mould 3 driving fits in the clamping plate 2, the elevating lever 61 of oil hydraulic cylinder 6 can be toward descending, thereby affect hook plate 42 toward after-drawing, facilitate 41 of 40 of shanks and movable shanks to utilize the powerful strength that generation is drawn mutually that hooks together mutually, and make tightly driving fit of mould 3, do not have the phenomenon that woolen cloth overflows, can matched moulds not inaccurate and shorten die life yet;

2. when the mutual driving fit of hook plate and shank sub-assembly 4, because of 2 of the left ends among the bar A43 that cranks arm, 3 of the bar B44 of cranking arm surpass central point, and make the pulling force that produces an independence between 41 of 40 of shanks and the movable shanks, therefore at blowpipe during to mould 3 blow moldings, can not rebound between above-mentioned two tripper heads, not take place so do not have the phenomenon of bounce-back mould between mould yet;

3. when mould will divided mould behind blow molding, oil hydraulic cylinder 6 can rise, this moment, crank arm bar A, B can push away the shank 40 in hook plate and the shank sub-assembly 4 forward because of the relation of elevating lever 61, when 41 junctions with hook plate 42 of movable shank move forward above pulley 57, movable tripper head can be down curved automatically, and make the output that does not hinder finished product after the die sinking.By above-mentioned 3 points, illustrated that obviously this novel member has overcome existing shortcoming in the prior art fully, it makes, and the mould driving fit is tight, accurate, no woolen cloth overflows, guarantee that not only mould is injury-free, increase the service life, and guaranteed the quality of finished product, best yield rate is increased.
