With accompanying drawing embodiment of the present utility model is illustrated below, description architecture principle at first: see Fig. 1, in normal working conditions, cylinder 1, mode transfer frame 22, chute 9 are relatively-stationary with frame 17, mould bases 15 can only up-and-down movement in mode transfer bar 12, represent with H among the vertical range figure, cylinder 1 piston rod drives pull bar 4, thereby drive the motion of mould bases 15, mould bases 15 bottoms are by link pin 21 articulated linkage 18, connecting rod 18 is hinged on the template 20, and the motion of mould bases 15 will drive template 20 motions like this.Because template 20 is fixed on the pulley 13 by connecting rod 16, and pulley 13 can only horizontal slip on guide rail 30, this just limits moving up and down of template 20, about carrying out, 20 of templates move back and forth, the scope of activities of template 20 represents with W, state diagram when Fig. 1 mid point is scribed ss complete machine and relatively moves ultimate range.
The concrete structure of these plastics clamping is mainly referring to Fig. 2 and Fig. 3 and Fig. 4.Clamping integral body is vertical type.Its guiding mechanism is that mode transfer frame 22 is fixed on the frame 17, its four corners position vertically stretches out four mode transfer bars 12 downwards with the state of being symmetrical arranged, mode transfer bar 12 is to be threaded on the mode transfer frame 22, mode transfer bar 12 interfixes with chute 9, fixed form is that step 28 is set on mode transfer bar 12, chute 9 is provided with through hole, is enclosed within on the mode transfer bar 12, use again bolt 29 with chute 9 clampings on mode transfer bar 12.Mould bases 15 is provided with pilot hole, is fixed with guide pin bushing 14 on the pilot hole, and mode transfer bar 12 lower ends slide in the guide pin bushing 14, can only be moved back and forth vertically by mode transfer bar 12 guiding mould bases 15.
Its translation mechanism is chute 9 built-in left skateboards 11, with right slide plate 11, structure is referring to Fig. 5, go slick for making, every each tumbler of slide plate 11 both sides has two pulleys 13, on two closed slides 30 of pulley 13 horizontal rollings in chute 9, have the dead slot structure on 11 on the slide plate, get out of the way mode transfer bar 12 and pull bar 4 moving positions, be fixed with connecting rod 16 on the slide plate 11, monolithic slide plate 11 structures are seen Fig. 7.Mould bases 15 drives two template 20 relative foldings by lower link 18, template 20 owing to the structure of top slide plate 11 causes can only horizontal move left and right, and can not vertically move.
The embodiment hoisting mechanism is: cylinder 1 places the center, the top, and cylinder 1 is fixed on the fixed mount 2, and fixed mount 2 passes mode transfer frame 22, is fixed on the chute 9.Cylinder 1 piston rod is hinged with pull bar 4, the through hole that pull bar 4 passes chute 9 is fixed on the mould bases 15, this example is to be fixed with connecting plate on cylinder 1 piston rod, connect pull bar 4 on the connecting plate, the through hole that pull bar 4 passes on the chute 9 is fixed on the mould bases 15, drives mould bases 15 by cylinder 1 and vertically moves back and forth.Present embodiment can make template 20 constant with the relative position of mould bases 15 when adjusting chute 9 height.
Cylinder 1 also can directly be fixed on other places of frame 17 except that the said fixing mode; Can also be fixed on the mode transfer frame 22, when adopting these two kinds of methods, thereby when adjusting mode transfer bar 12 and adjust chutes 9 height, must adjust pull bar 4 simultaneously, thereby adjust the height of mould bases 15, to adapt to the optimum position of connecting rod 18 when the matched moulds.
On this matched mould mechanism for plastics forming process; returning apparatus has the mould adjusting mechanism of upper-lower position when adjusting template 20 initializations; see shown in Figure 11; the mode transfer bar 12 tops mode transfer sleeve 8 that has been threaded; it is rotatably mounted on the mode transfer frame 22 with bearing 10; can not go here and there the mode transfer sleeve 8 outer sprocket wheels 7 of fixing up and down.Worm gear 5 worm screws 6 devices are housed on the mode transfer bar 12 in four mode transfer bars 12, and sprocket wheel 7 links to each other with worm gear 5, and worm gear 5 is driven by worm screw 6, and worm screw links to each other with additionaling power, and additionaling power can be manpower, also useable electric moter.Sprocket wheel 7 on four mode transfer bars 12 links together with chain 3 mutually mutually.So when worm screw 6 drives worm gear 5 and sprocket wheel 7 and 8 rotations of mode transfer sleeve, by chain 3 effects, four mode transfer bars 12 are under threaded function, move up and down synchronously, thereby driving chute 9 and slide plate 11 moves up and down, slide plate 11 is divided into 11 two on left skateboard 11 and right slide plate, left and right slide plate 11 drive respectively each connecting rod 16 and with the moving up and down of its fixing left template 20 and right template 20, with this establish template 20 with and on the virgin work position of mould.
This matched mould mechanism for plastics forming process is rational in infrastructure; easy to operate; cylinder 1 work; drive pull bar 4 and then drive mould bases 15 motions; mould bases 15 is by the pilot hole on the guide pin bushing 14; on mode transfer bar 12; do vertically and reciprocatingly slide; when mould bases 15 passes through link pin 21; when bearing 19 acts on connecting rod 18; connecting rod 18 will drive template 20 motions by bearing 19; a because left side; right template 20 is fixed on a left side by connecting rod 16; on the right slide plate 11; slide plate 11 moves both vertically and is subjected to chute 9 restrictions; but can horizontal displacement by pulley 13 and 30 effects of two closed slides; thereby under deadweight and connecting rod 18 pulling force effects, template 20 has produced horizontal reciprocating movement, and structure Design makes two templates 20 be equidistant relatively clutch; and because of connecting rod 18 strokes weak point; can adjust it during matched moulds and be in level, so mold clamping force is big, this has just satisfied the technological requirement of making plastic products.When using different moulds to make multiple product, change new die on the template 20, its initialization state is regulated by the worm gear 5 of mould adjusting mechanism, the vertical range of 6 pairs of templates 20 of worm screw.Adjust the initial level distance of template 20 foldings by screw rod 27, slide block 26.The space is bigger in the mould bases 15, and blowing machinery can place the forward and backward or upper position of template 20 as required, and adaptability is strong.
