Detailed description of the invention
The present invention is described in further detail respectively by three kinds of different function modes with most preferred embodiment below in conjunction with accompanying drawing:
One, double coloured plastic injection machine of the present invention operates in " clear double-colored core rotation type " mode:
As shown in Figure 2, double coloured plastic injection machine of the present invention, comprises moving platen 1, and described moving platen 1 fixedly mounts bottom plate of turntable 4, and servo motor 2 and reductor 3 are equipped with in the upper end of bottom plate of turntable 4.Moving platen center arranges pivoted housing 14, and pivoted housing 14 is fixedly connected with rotating disk 9.Upper end fixed installation driving shaft support 7 on the right side of rotating disk 9, driving shaft support 7 is connected with the right-hand member of driving shaft 5, and the left end of driving shaft 5 is fixed on reductor 3, driving shaft 5 is equipped with Timing Belt driving wheel 6.Rotating disk 9 is installed bull gear 10, idler gear 8 is set between bull gear 10 and driving shaft 5.The right center place fixed installation driven pulley bearing 21 of rotating disk 9, arranges clutch shaft bearing 16 on the right side of driven pulley bearing 21, the outer ring fixed installation Timing Belt driven pulley 15 of clutch shaft bearing 16 and driven pulley gland 17.The right side of rotating disk 9 also arranges water pipe ditch, arranges cooling water fishplate bar 11 in water pipe ditch.Rotating disk 9 fixedly mounts die backing plate 12, as shown in Figure 1, regulating block 39 and regulating block screw 29 are set in die backing plate 12.Turn regulating block 39 and the regulating block screw 29 of the left and right sides respectively, just adjustable driven pulley gland 17 initial 0 ° and stop the exact position of 180 ° of rotating.
As shown in Figure 2, the left side arranging the second bearing 22 and the 3rd bearing the 23, three bearing 23 between described pivoted housing 14 and the centre bore of moving platen 1 sets gradually backing plate 37, the 4th bearing 36, adjusting nut 35.Pivoted housing 14 endoporus place sets gradually from outside to inside and turns core oil cylinder 38, piston rod 34, turns core 28.Piston rod 34 right-hand member and turn between core 28 right-hand member the 5th bearing 20 is set, oil jacket 33 is joined in the left end fixed installation of piston rod 34, join oil jacket 33 left end to arrange the 6th bearing the 32, five bearing 20 and the 6th bearing 32 and make to turn core 28 and follow piston rod 34 and do jacking or top deactuate is done.The left end turning core 28 arranges water distribution cover 31, and one end of orientation lever 30 is fixed on water distribution cover 31, and the other end is placed in the groove of gunning stick 27.Turn the fixed installation of core 28 right-hand member and turn core extension bar 18, turn the centre bore of core extension bar 18 through die backing plate 12, the core rod 19 of mould is fixedly mounted on and turns on core extension bar 18.Described driven pulley gland 17 endoporus has a square projection to embed the groove turned on core extension bar 18 cylindrical, turns core extension bar 18, core rod 19 follows rotation when driven pulley gland 17 is rotated.Described rotating disk 9 also arranges positioning sleeve 24, arranges positioning piston bar 25 in moving platen 1, the outer of rotating disk 9 arranges rotating disk pressing plate 26.
Operation principle: servo motor 2 rotates, is made to turn core extension bar 18 rotated by reductor 3, driving shaft 5, Timing Belt driving wheel 6, Timing Belt 13, Timing Belt driven pulley 15, driven pulley gland 17, thus band moving-mould-core 19 rotates.As mentioned above, accurately located by two pieces regulating block 39 with the position stopping 180 ° for initial 0 ° of core rod 19 rotation; Simultaneously by controlling two hydraulic fluid port liquid in-out force feeds of joining on oil jacket 33, the axial jacking and the top that realize core rod 19 are moved back, then change mold cavity in conjunction with the rotary motion of core rod 19.Move back in course of action in jacking and top, described orientation lever 30 slides in the groove of gunning stick 27, overlaps 31 transfers to prevent water distribution.All the time be inserted in positioning sleeve 24 in case spline dish 9 rotates at whole injection cycle positioning piston bar 25.
When double coloured plastic injection machine of the present invention is used as this " clear double-colored core rotation type " mode, as shown in Figure 5, two strands of sizing materials inject two die cavities of mould to the structure of its solid plate 61 and stationary mould for mould plate one side of something 62 respectively.
Two, double coloured plastic injection machine of the present invention operates in " clear Double-color rotary table formula " mode:
When transferring to " clear Double-color rotary table formula " by " clear double-colored core rotation type ", the installation steps of machine are: as shown in Figure 2, pull down driving shaft and Timing Belt driving wheel and driving shaft support, die backing plate 12, Timing Belt 13, turn core extension bar 18, driven pulley bearing 21.As shown in Figure 4, the output shaft of reductor 3 installs driven wheel 51, this gear engages with idler gear 8; Turning right-hand member fixed installation water pipe cover plate 54, alignment pin 55, the cooling water pipe 53 of core 28, the other end of cooling water pipe 53 is connected to cooling water fishplate bar 11; Rotating disk 9 is installed water pipe ditch shrouding 52.Moving platen one side of something of mould is arranged on rotating disk 9.
Operation principle: as shown in Figure 4, servo motor 2 rotates, and drives rotating disk 9 to rotate by reductor 3, driven wheel 51, idler gear 8, bull gear 10, and rotating disk 9 drives pivoted housing 14, alignment pin 55, water pipe cover plate 54, turn core 28 rotates.Now piston rod 34 is in the position that top falls back on the end.Because orientation lever 30 is placed in the groove of gunning stick 27, water distribution cover 31 is not followed and is turned core 28 and rotate.For the axial limiting of rotating disk 9, there is gap between contact surface between the two in rotating disk pressing plate 26, ensures the rotation at die opening state lower rotary table 9.In rotating disk 9 rotary course, positioning piston bar 25 is in the position of retraction, and when rotating disk 9 forwards position (initial 0 ° or termination 180 °) to, positioning piston bar 25 inserts in positioning sleeve 24 and realizes accurately location.
When double coloured plastic injection machine of the present invention is used as this " clear Double-color rotary table formula " mode, as shown in Figure 5, two strands of sizing materials inject two die cavities of mould to the structure of its solid plate 61 and stationary mould for mould plate one side of something 62 respectively.
Three, double coloured plastic injection machine of the present invention operates in " colour mixture " mode:
As shown in Figure 6, moving platen part uses " clear Double-color rotary table formula " structure in this mode, and the code die face of solid plate 61 installs colo(u)r mixer 71.One end of described colo(u)r mixer 71 arranges two and injects runner, communicates respectively with two nozzles injecting different colours sizing material; The other end arranges an injection runner, and described injection runner connects nozzle 74, and the sizing material after colour mixture is injected mould.
Arrange spool 73 between described two injection runners and described injection runner, spool 73 follow procedure control overflow opens and closes action, controls the mixed effect of two kinds of colors.For making inside have sufficiently high temperature smooth and easy to make sizing material flow, the outer surface of colo(u)r mixer 71 installs electric boiling plate 72.
Specific embodiment described in this description, the profile, internal structure etc. of its parts can be different.Allly conceive according to the present invention the equivalent transformation that described structure, feature and principle do, be included in the protection domain of patent of the present invention.
