The specific embodiment
Describe the utility model in detail below in conjunction with accompanying drawing, it is more obvious that the purpose of this utility model and effect will become.
Referring to Fig. 1～shown in Figure 3, brake sticking device of double-plate injection moulding machine of the present utility model comprises moving platen 1, the first hold-fast body 2, toggle 3, following free bearing 4, the second hold-fast bodies 5, obvolvent cylinder body 6, obvolvent oil cylinder piston bar 7, last free bearing 8, pull bar 9 and guide rod 10, wherein first hold-fast body 2 comprises first baffle plate, 21, the first upper plates, 22, the first outer slides 23, first inner slide, 2 24, first lower shoe 25; Second hold-fast body 5 comprises second baffle 51, the second upper plates 52, the second outer slides 53, the second inner slides 54, the second lower shoes 55, and hold-fast body distributes diagonally.
As shown in Figure 1, the piston rod 7 of obvolvent oil cylinder is connected with last free bearing 8, cylinder body 6 is connected with following free bearing 4, last free bearing 8 is formed elbow-bar mechanism with two toggles 3 again and is hinged with first hold-fast body 2 and second hold-fast body 5 of moving platen 1 top respectively, following free bearing 4 is also formed elbow-bar mechanism with two toggles 3, and to hold 5 mechanisms tightly hinged with first hold-fast body 2 and second of moving platen 1 below respectively, and first hold-fast body 2 up and down interlocks by four pull bars 9 respectively with second hold-fast body 5 again and links to each other simultaneously.
As shown in Figure 2, first outer slide 23 in first hold-fast body 2 and first inner slide 24 are positioned at first upper plate 22, first lower shoe 25 and casing that four first baffle plates 21 are formed, this casing is fixed on the moving platen 1 by first upper plate 22 and first lower shoe 25, and the stroke of 21 pairs of slide blocks of first baffle plate plays position-limiting action; Have the recessed hackle mark that matches with guide rod 10 epirelief hackle marks on first outer slide 23 and first inner slide 24, under the driving of obvolvent oil cylinder, promote that two slide blocks are done in opposite directions or, guide rod 10 is carried out band-type brake or opens a sluice gate from motion.Structure for second hold-fast body 5 is formed in like manner.
As shown in Figure 3, first hold-fast body 2 and second hold-fast body 5 are hinged with toggle 3 by first inner slide 24 and second inner slide 54 respectively; And connect in four pull bars 9 of first hold-fast body 2 and second hold-fast body 5, wherein two pull bars 9 near obvolvent oil cylinder one side pass second inner slide 54, connect to live first inner slide 24 and second outer slide 53; Two pull bars of an in like manner other side pass first inner slide 24, connect to live first outer slide 23 and second inner slide 54.
As Fig. 1～shown in Figure 3, the novel course of work of this example is: when carrying out matched moulds, die cylinder drive moving platen 10 advances fast at first fast, when moving platen 10 arrives the default position, system's control band brake apparatus begins to carry out band-type brake, the obvolvent oil cylinder produces action, cylinder body 6 and piston rod 7 drive free bearing 8 respectively and following free bearing 4 is made move toward one another, wherein which free bearing motion earlier, movement velocity comparatively fast and earlier reaches self-locking state and depends on its suffered relevant frictional force, press close to the link stopper that first inner slide 24 and second inner slide 54 stretch out earlier when the toggle 3 of an elbow-bar mechanism and enter self-locking state, the another one elbow-bar mechanism continues motion then, free bearing promotes two slide blocks by toggle 3 and does relative motion, in like manner which slide block elder generation contact guide rod depends on its suffered force of sliding friction, all enter self-locking state until last free bearing 8 and following free bearing 4 then, this moment, two slide blocks were held guide rod 5 tightly, after corresponding sensor detects the band brake apparatus obvolvent, send signal controlling oil cylinder fuel cut-off, because elbow-bar mechanism has entered self-locking state, keeping the power of holding tightly can be carried enough by self-lock force, as long as so close the inlet valve of obvolvent oil cylinder, need not to carry again the enough energy, finish to this band-type brake process.When carrying out die sinking, system's control obvolvent oil cylinder counter motion promotes the opposing motion of sliding, and hold-fast body unclamps guide rod 10, and the rapid mould-moving oil cylinder drives moving platen 1 motion then.
