Description
Technical field
The utility model relates to a kind of band-type brake mechanism of injection machine.
Background technology
The band-type brake mechanism of existing injection machine, four pull bars have respectively disposed an independent band brake apparatus and have carried out obvolvent.In practical work process, when obvolvent be closed to the end, when obvolvent is opened to the end, very big impact sound is sent in the capital, this mainly is because opening with obvolvent of a pair of cohesion nut is not synchronous, when one side of something of cohesion nut and limited block or pull bar collision, oil cylinder is position on earth not also, and this moment, velocity ratio was bigger, so can produce strike note.
The utility model content
Technical problem to be solved in the utility model is the band-type brake mechanism that a kind of injection machine is provided for the above-mentioned deficiency that overcomes prior art, makes its band-type brake synchronously.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the band-type brake mechanism of injection machine, comprise two double cohesion nuts and oil cylinder, two double cohesion nuts are as a cover mechanism, one of them outside one side of something to half-nut connects with rod member the inboard half of of half-nut with another, and the inboard one side of something to half-nut connects with rod member with another outside one side of something to nut; The piston rod and the cylinder body that connect oil cylinder between inboard one side of something of two double cohesion nuts respectively, oil cylinder make cohesion nut two medial movement and realize the synchronous obvolvent of cohesion nut and open; Connect between two inboard one side of something of two pairs of cohesion nuts and guarantee inboard half of synchronous linkage, linkage comprises synchronising (connecting) rod and synchronous element of two equal in length, synchronising (connecting) rod one end links to each other with an inboard to half-nut, the other end of a synchronising (connecting) rod links to each other with synchronous element, one end of another synchronising (connecting) rod links to each other with another inboard to half-nut, and the other end of another synchronising (connecting) rod links to each other with synchronous element.
Better, above-mentioned synchronous element is also led by guide.
Better, in the above-mentioned driving oil cylinder buffer gear is set.
Compared with prior art, advantage of the present utility model is: 1, because two pairs of cohesion nuts of band-type brake mechanism are realized action synchronously by linkage and rod member, and not only working stability but also seldom noise, and good synchronously.2, by driving hydraulic oil cylinder driving, can be undertaken spacing by driving oil cylinder self.3, drive oil cylinder and be provided with buffer gear, obvolvent is more steady.
Description of drawings

Fig. 3 is two pairs of cohesion nut connecting rods of the utility model embodiment connected mode cutaway view.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figures 1 to 3, injection machine obvolvent mechanism comprises moving platen 1, and is in 4 pull bars 29 between moving platen 1 and these two templates of solid plate (not marking among the figure).
On moving platen 1, two cover band-type brake mechanisms 2 and 3 are arranged respectively.Band-type brake mechanism 2 residing positions be locking and the position shown in the band-type brake mechanism 3 is to open.
With band-type brake mechanism 2 is example, comprises two double cohesion nuts 8,9, and cohesion nut half shell 4,5,6,7 is fixed on the moving platen 1 by two cohesion nut guide plates 24, the motion of restriction cohesion nut half shell 4,5,6,7 left and right directions.
Above-mentioned cohesion nut half shell 5 and 6 is connected on the piston rod and cylinder body of cylinder component 20 by contiguous block 19 and 23.
In order to reduce the processing of piston rod 21, increase by one section piston extension rod 22 especially, piston extension rod 22 1 ends are connected with piston rod 21 by piston rod adapter sleeve 28, and piston extension rod 2 other ends link to each other with contiguous block 23 by piston rod connector 27.
By contiguous block 25 and 26 band-type brake synchronising (connecting) rod 10 and 11 is connected on the synchronous element 12 simultaneously, band-type brake synchronising (connecting) rod 10 and 11 equal in length, each junction connects with pin.
Two guide posts 13 pass synchronous element 12, and guide post 13 is fixed on the moving platen 1 by the synchronous support 14 of band-type brake simultaneously, so just can guarantee synchronous element 12 rectilinear motions.Band-type brake synchronising (connecting) rod 10 and 11 equal in length so just can make half shell 5 can do move toward one another with identical speed with 6.
Cohesion nut half shell 4 links to each other with 17 by the connecting rod of placing according to diagonal 16 with 6, and cohesion nut half shell 5 is covered by connecting rod 17 with 18(by the connecting rod of placing according to diagonal 15 with 7) link to each other, as Fig. 1, Fig. 2, shown in Figure 3.
When band-type brake mechanism 2 needed the obvolvent action, the piston rod 19 of oil cylinder stretched out, and promoted half shell 4 and 5 and moved round about, because synchronous element 12 is arranged, the speed of half shell 4 and 5 equates.Again since half shell 5 link to each other by connecting rod with 6 with 7 and half shell 4, so their speed is identical, so just can be when obvolvent, last lower nut reaches the while obvolvent.
On the contrary, when band-type brake mechanism 2 need open, the piston rod of oil cylinder 19 was regained, and spurred half shell 4 and 5 and move round about, again owing to half shell 7 links to each other by connecting rod with 6 with 5 and half shell 4, so half shell 4 and 5, half shell 7 and 5 can leave synchronously.
