The cooling system of injection mold occupies very critical role in the design of injection mold, is the key of improving injection-molded item quality, improving injection mo(u)lding efficiency.The design of tradition cooling system relies on experience mostly, the restriction of traditional machining process in addition, and traditional design of Cooling System is difficult to reach evenly cooling requirement.In order to improve cooling effect, there is conformal cooling technology, cooling water channel changes according to the variation of product design, can realize evenly coolingly, improves the quality of goods, reduces cool time, has very strong applicability.Full-fledged along with rapid shaping technique (now claiming three-dimensional printing technology), has created condition for manufacturing and designing conformal cooling mould, has expanded the application of conformal cooling technology.But the design of conformal cooling channel mould generally only considers that water channel conformal is to the cooling impact bringing, the impact of the concrete structure such as shape and internal structure that reckons without cooling water channel itself on conformal cooling effect and efficiency.
Utility model content
The purpose of this utility model is to overcome the shortcoming that prior art exists, in Design and Manufacture of Plastic Injection Mould, a kind of novel conformal cooling channel is provided, by changing the structure of cooling water channel itself, make cooling medium form forced turbulent, augmentation of heat transfer in the inside of cooling water channel, strengthen the cooling effect of cooling medium, thereby the cooling effectiveness and the quality that improve injection-molded item, shortening injection molding cycle, enhances productivity.
The purpose of this utility model realizes by following technical method:
A kind of special-shaped water channel conformal cooling injection mold, comprise dynamic model and cover half, also comprise the core being arranged between dynamic model and cover half, die cavity, impression bolster, core fixing plate, described impression bolster is fixed by screws in cover half lower end, described core fixing plate is fixed by screws in dynamic model upper end, described die cavity is inlayed and is fixed on impression bolster, described core is inlayed and is fixed on core fixing plate, described core, die cavity inside is provided with the mobile conformal cooling channel of Cooling Water, described conformal cooling channel is helicla flute line tubulose, convergent-divergent tubulose, corrugated tube shape, transversally flute tube shape or spiral flat tube shape.
Further, between described die cavity and cover half, be respectively arranged with sealing ring between described dynamic model and core, on described fixed half and moving half, be provided with the seal groove for placing sealing ring.
Further, in described fixed half and moving half, be provided with the connection water channel for connecting external refrigeration water supply system and conformal cooling channel.
Compared with prior art, the utlity model has following beneficial effect:
(1) the utility model separates the manufacture of the core with conformal cooling channel, die cavity and the processing of template, only adopt quick shaping process to manufacture to the core with conformal cooling channel part and die cavity, manufacture working (machining) efficiency to improve, cut down finished cost.
(2) template and core, die cavity adopt combined type, once core, die cavity damage or occur defect, are convenient to dismounting and repair or change.
(3) cooling water channel adopts special-shaped water channel, thereby increases the disturbance of cooling medium in cooling water channel, forms turbulence effect, has strengthened heat-transfer effect.
