Running gate system uses hot runner gate directly to enter mode of watering, and hot runner manifold 35 is positioned between top panel 3 and A plate 5, and
Heat insulation by hot flow path heat insulation tie-plate 4, hot runner manifold cushion block 2 provide support, to reduce the heat transfer between hot runner manifold and template.
After plastics material stream is injected hot runner manifold 35 by injection molding machine nozzle, under injection machine injection pressure, inject mould by hot runner gate 24
In tool die cavity.
Mould molding part composition includes that A plate 5, jacking block 6, water route 7, each slider head, core mold insert 9 etc. are constituted, Qi Zhongkao
Considering to die cavity strength problem, die cavity directly uses monoblock type mode, is i.e. directly gone out by Milling Process on A plate 5, and core then adds
Work forming core mold insert 9 is inlayed spelling and is installed on B plate 11, is beneficial to processing and the installation of other part.
It is fixed that guided positioning system includes that cavity closed guide-localization, ejecting mechanism guide-localization, core-drawing demoulding mechanism guide
Position.The Guan Bi guide-localization of die cavity is completed by guide pillar 32 and supporting guide pin bushing thereof, is designed with die cavity outer side edges location wear-resisting simultaneously
Repetitive positioning accuracy when wearing plate 22 ensures cavity closed is positioned inside plate 20, side location plate 21, die cavity, and by closing
Modal balancing 31 ensures balance and the stationarity that during Guan Bi, A plate 5 and B plate 11 coordinates.The guide-localization of ejecting mechanism is led by push pedal
Post 15 and be installed on the supporting guide pin bushing ejecting in push pedal 13 and complete.The guiding of mould emptier in two kinds of situation, Angle Pin slide block
Being guided by slider layering during mechanism's slide body motion, the guiding of oil cylinder T-slot break-in core-pulling sliding block mechanism is then by T-slot pedestal
On T-slot slip tunnel slide block is guided.
Cooling system uses water-cooling pattern, and layout of beam line mode uses direct current duct type and the well type of cooling；Die cavity sets
Count 17 direct current pipelines, all use diameterWater cooled pipeline, for ensureing the harmony of cooling, wherein 11 water inlet sides
To in opposite direction with other 6 water inlets；12 water routes of core designs, 8 strip adoption pipelines introduce, and the well type of cooling is adopted for 4
Use direct current pipe method.The inflow temperature of cooling water is controlled by mold flow analysis result.
Gas extraction system PP material overflow edge value is 0.03mm, therefore big in view of mold cavity volume, and capacity is many, except utilizing between slider head
Outside the aerofluxuss such as gap, mold insert gap, at parting line periphery design, width is 12mm, and the air discharge duct of deep 0.02mm, according to mould flow point
Analysis result.
For overcoming product to tighten up a screw release problems recessed on the upside of hole side opening and wall, the first Angle Pin side slide the 8, the 3rd is tiltedly led
Post side slide the 25, second Angle Pin side slide the 26, the 4th Angle Pin side slide 34 uses common Angle Pin slide block core pulling structure
Mode, and restriction the first oil cylinder T-slot break-in core-pulling sliding block mechanism the 27, the second cylinder T-slot break-in being limited to die space is loosed core
Slide block mechanism 33 then uses oil cylinder T-slot break-in core-pulling sliding block mechanism mode, and its operation principle is that side core-pulling type pin is installed on and takes out
The upper end of core slide block 38, when actuator cylinder 45 action pull oil cylinder take out core bar 44 loose core by K direction time, tunnel slide block 40 is by it
On T-slot, pull matched core-pulling slide block 38 do along F to adverse movement, it is achieved core-pulling slide block 38 along G direction point
Motion, thus realize the extraction from product of the side core-pulling type pin；The core pulling distance of tunnel slide block 40 is by stroke limit post 42, stroke
The contact of switch 43 controls to realize.
When mold work principle mould produces after being installed on injection machine, its work process is divided into following steps:
(1) injection, is full of die cavity by hot flow path by injection machine, and after cooling, the demoulding for product is prepared.
(2) die sinking, cools down complete, and mould is retrogressing under the pulling of Injection Motor Template, and mould is opened at PL die joint,
Complete the demoulding of product cavity surface.Meanwhile, Angle Pin slide block completes its slider head moulding section and product separation.
(3) type pin is loosed core, and after mould is opened, uses oil cylinder T-slot break-in core-pulling sliding block mechanism drawing at actuator cylinder 45
Under Dong, complete small-sized pin and product separation.
(4) the ejecting completely of product, small-sized core needle is loosed core complete, and push pedal actuator cylinder 30 pulls up and ejects push pedal 13 and push away
Dynamic jacking block 6, thimble 37 by product ejection device from core mold insert 9, thus realize product be automatically molded production.
(5) resetting, during mould Guan Bi, ejecting mechanism first resets, and rear mold Guan Bi, Angle Pin slide block resets, and is then
The reset of small-sized pin on oil cylinder T-slot break-in core-pulling sliding block mechanism, mould resets completely, waits opening of next injection cycle
Begin.
Big for vehicle right and left rear-wheel hub cover product size, the actual production difficult problem that during injection, difficulty filling is full is logical
Cross CAE optimize analyze, determine employing hot channel injecting formation scheme, plastic is being made optimal pouring position, cast gate quantity with
And pouring type etc. is made that after sufficiently optimizing and analyzing, construct 6 hot runner gate direct moulding by casting schemes of product, and
Combine targetedly and produce physical device, the cae analysis result of 6 casting programs has been done the equipment quantitative associativity work of orientation
Skill is analyzed, and provides strong accurate data analysis for Design of Dies, it is to avoid only according to knowhow brought uncertain because of
Element manufactures risk, improves mould production efficiency, reduces production cost.
Obviously, embodiments described above is a part of embodiment of this utility model rather than whole embodiments.Base
Embodiment in this utility model, the institute that those of ordinary skill in the art are obtained under not making creative work premise
There are other embodiments, broadly fall into the scope of this utility model protection.
