Description
Technical field
The utility model relates to a kind of mechanism of two plate machine formula injection machines, particularly its band-type brake mechanism.
Background technology
The double-plate Mould Clamping Mechanism of Injection Moulding Machine is owing to no crank connecting rod device, so mechanism kinematic pairs reduces in a large number.Because the minimizing of mechanical quick-wear part, extend the service life of machine greatly.The double-plate Mould Clamping Mechanism of Injection Moulding Machine is compared traditional mould clamping mechanism of crank connecting rod in addition, has lacked a mode transfer template, and this has reduced the cost of machine significantly for medium-and-large-sized machine.Because moving die plate and pull bar are thrown off during this type die sinking, moving die plate is locked by a mechanism with pull bar again during high-voltage lock mould, and this mechanism is referred to as band-type brake mechanism on the double-plate plastic-injection moulding machine.
Existing double-plate plastic-injection moulding machine band-type brake mechanism adopts relatively independent quadruplet hydraulic-driven band-type brake mechanism, because every cover band-type brake mechanism suffered frictional resistance difference when motion, synchronism during this quadruplet band-type brake mechanism action will be affected, often cause cover band-type brake mechanism execution, other band-type brake mechanism is but also in running, prolonged and finished the required time of whole band-type brake, thereby also increased the cycle period of whole injection machine.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of prior art and a kind of band-type brake mechanism is provided, and makes its designs simplification, band-type brake speed is fast, synchronism good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
Two plate machine formula injection machine band-type brake mechanisms, comprise four band-type brake nuts and drive oil cylinder, it is characterized in that: four band-type brake nuts are divided into two groups up and down of same structure, two band-type brake nuts about every group of band-type brake nut is divided into, driving oil cylinder one end is fixed on the right side half band-type brake nut of left band-type brake nut, the piston rod that drives oil cylinder is connected with the left half-nut of right band-type brake nut, the a left side half band-type brake nut of left side band-type brake nut and a left side half band-type brake nut of right band-type brake nut, the right side half band-type brake nut of left side band-type brake nut is connected by connecting rod with the right side half band-type brake nut of right band-type brake nut, and the right side half band-type brake nut of left band-type brake nut also is connected with simultaneous attachment mechanism with a left side half band-type brake nut of right band-type brake nut.
Above-mentioned simultaneous attachment mechanism is two connecting rods and rotating stand, one connecting rod, one end is connected with the right side half band-type brake nut of left band-type brake nut, this connecting rod other end is connected with a side of rotating stand, another connecting rod one end is connected with a left side half band-type brake nut of right band-type brake nut, and another connecting rod other end is connected with the opposite side of rotating stand.
Compared with prior art, advantage of the present utility model is:
1, because band-type brake mechanism is divided into two relatively independent cover mechanisms symmetry arrangement up and down, every cover drives two band-type brake nuts simultaneously by a hydraulic jack, design has synchronism mechanism between two band-type brake nuts, therefore can guarantee the synchronism of band-type brake mechanism operation, shorten the cycle of operation of band-type brake mechanism.
2,, therefore saved the cost of whole band-type brake mechanism owing to reduced the driving oil cylinder.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Shown in Fig. 1,2,3,8, two plate machine formula injection machines generally link together by fixed form 1, moving die plate 3 and tailstock 4 and by pull bar 2 and constitute the framework of whole injection machine.
As Fig. 5, shown in Figure 6, driving oil cylinder bonnet 18, driving cylinder tube 19, driving oil cylinder protecgulum 20, driving oil cylinder piston bar 21 are formed band-type brakes driving oil cylinders.
Driving oil cylinder piston bar 21 is connected with band-type brake nut-R 6 by connecting axle 23, and other end driving oil cylinder bonnet 18 is connected with band-type brake nut-R 9 with contiguous block 16 by connecting pin 17, wherein band-type brake nut-L 5 two connecting rods 7 of arranging by the diagonal angle are fixed together with band-type brake nut-R 9,6 two connecting rods 8 of arranging by the diagonal angle of band-type brake nut-R are fixed together with band-type brake nut-L 10, see Fig. 6, Fig. 7.
After quick matched moulds was finished, carried out band-type brake action by driving the oil cylinder rodless cavity oil-feed this moment.The lazy-tongs of being made up of synchronous connecting rod 12,14 and rotating stand 13 are connected generation synchronous interaction action with band-type brake nut-R 6 respectively with band-type brake nut-R 9 simultaneously.When band-type brake drives the oil cylinder rodless cavity oil-feed, drive oil cylinder piston bar 21 and make band-type brake nut-L 5 and band-type brake nut-R 6 and band-type brake nut-R 9 and band-type brake nut-L 10 finish the band-type brake action simultaneously, see the I state of Fig. 4; Otherwise, after injection is finished, do die sinking action before, band-type brake drives the cylinder rod chamber oil-feed, drive oil cylinder piston bar 21 and oppositely move, band-type brake nut-L 5 and band-type brake nut-R 6 and band-type brake nut-R 9 and band-type brake nut-L are finished synchronously open a sluice gate action, see the II state of Fig. 4.
