Description
Technical field
The utility model relates to injection molding of rubber field, refers to a kind of rubber inner-cooled flow passage system specifically.
Background technology
Rubber is widely used in the industry such as Aero-Space, machinery, electronics, traffic, building and some new industries as a kind of important material.Again can not plasticate because rubber is heated after sulfidization molding, so some waste materials produced in rubber curing forming process cannot directly reclaim and secondary utilizes, cause the great wasting of resources.
Current rubber product injection moulding is mainly adopted in two ways: a kind of is adopt common hot flow path injection system, and another kind adopts cold runner injection mode.And in existing rubber cold runner mould structure, be only that sprue bush outside has cooling.There is following defect in existing rubber cold runner mould: one, note mouth appearance and size huge, and the pin mark shape that cannot realize rubber product enters glue, the sizing material still existed between runner to product glue-feeder is wasted in a large number.Two, product glue-feeder cannot be realized densely arranged, thus cause arrangement mode and the limited amount of mold cavity.Three, because center cooling is not in place, stifled glue phenomenon is easily produced.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, the double circulation type of cooling that a kind of inside and outside cooling combines is provided, sizing material in runner and note mouth is fully cooled, effective control from main feeding mouth to product glue-feeder sizing material temperature, greatly reduce the waste of sizing material.
Technical problem of the present utility model is achieved through the following technical solutions: a kind of rubber inner-cooled flow passage system is provided with cold flow guidance tape, coldplate, thermal insulation board, cavity plate from top to bottom successively.Cold flow guidance tape center is provided with main feeding mouth, bottom surface is provided with horizontal run and communicates with main feeding mouth, horizontal run arranges branch according to the arrangement of mold cavity, the end of horizontal run branch communicates with the vertical runner in coldplate, and in coldplate, vertically runner is communicated with by noting mouth between product glue-feeder with in cavity plate.Be provided with center cooling stick in vertical runner and note mouth, cooling stick upper end, center is immersed in recirculated cooling water, and its end face is compressed by screw plug and seals, and its stepped portions is provided with sealing ring.Be respectively arranged with circulating cooling water route in cold flow guidance tape and coldplate, cool inside and outside note mouth and vertical runner.Lower end and the cavity plate contact site of note mouth are coated with heat insulating coat, between coldplate and cavity plate, be provided with thermal insulation board.The end of horizontal run branch is provided with flow regulator.Electric heater unit is provided with in cavity plate.
Beneficial effect: compared with prior art, the utility model mainly adopts rubber inner-cooled runner, the pin mark shape realizing rubber cold runner enters glue, without the need to removing separately runner waste material before next molding cycle, both economized on resources, shorten molding cycle again, realize the continuous automatic production of injection molding of rubber; This cold runner system compact conformation, can realize the densely arranged of product glue-feeder, thus makes the arrangement mode of mold cavity and quantity more reasonable; Inside and outside cooling combines, and runner is more abundant with sizing material cooling in note mouth, is not easy to produce stifled glue phenomenon.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of rubber inner-cooled flow passage system described in the utility model comprises, 1. main feeding mouth, 2. horizontal run, 3. flow regulator, 4. center cooling stick, 5. vertical runner, 6. circulating cooling water route, 7. circulating cooling water route, 8. note mouth, 9. product glue-feeder, 10. electric heater unit, 11. cavity plate, 12. thermal insulation boards, 13. coldplates, 14. cold flow guidance tapes, 15. screw plugs.
Main feeding mouth 1 is provided with at the center of cold flow guidance tape 14, bottom surface is provided with horizontal run 2 and communicates with main feeding mouth 1, horizontal run 2 can arrange branch according to the mold cavity situation of arranging, the end of each horizontal run branch communicates with the vertical runner 5 be arranged in coldplate 13, is communicated with between vertical runner with the product glue-feeder 9 be arranged in cavity plate 11 by noting mouth 8.Be provided with center cooling stick 4 in vertical runner 5 and note mouth 8, cooling stick upper end, center is immersed in recirculated cooling water.Connected by high strength hexagon socket head cap screw between cold flow guidance tape 14, coldplate 13, thermal insulation board 12 and cavity plate 11.
The copper rod that center cooling stick 4 adopts pyroconductivity high or heat-conducting copper pipe, take the heat of sizing material in vertical runner and note mouth to colling end fast.Insert from top to bottom when center cooling stick 4 is installed in cold flow guidance tape 14, its end face is compressed by screw plug 15 and seals, and its stepped portions is provided with sealing ring, and lower end is conical.
In cold flow guidance tape 14, be provided with 6 pairs, circulating cooling water route center cooling stick 4 and horizontal run 2 cools, in coldplate 13, being provided with circulating cooling water route 7, outside and vertical runner 5 cools to note mouth 8.Inside and outside cool the double circulation type of cooling combined, the sizing material temperature can effectively controlling from main feeding mouth 1 to product glue-feeder 9, makes sizing material neither cure in runner, can keep certain mobility again.
Lower end and cavity plate 11 contact site of note mouth 8 are coated with heat insulating coat, intercept the heat transmission between note mouth 8 and cavity plate 11, the thermal insulation board 12 simultaneously adopting high-effect heat-barrier material to make, to intercept the heat transmission between cavity plate 11 and coldplate 13, realizes the effective control to sizing material temperature in runner further.
The end of horizontal run 2 branch is provided with flow regulator 3, is adjusted the sizing material flow of each product glue-feeder by the rotation of adjusting device.
Be provided with electric heater unit 10 in cavity plate 11, directly mold cavity heated.Product glue-feeder 9 in cavity plate 11 is pin dots structure, and the pin mark shape realizing rubber product enters glue, and on product after shaping, the residual trace of glue-feeder is very little.
