Description
Technical field:
The utility model relates to a kind of injection molding of rubber mould that comprises dynamic model and cover half in the rubber and plastic processing and manufacturing field, particularly a kind of cold runner injection molding of rubber mould.
Background technology:
Present injection molding of rubber method is to be injected into and to carry out sulfidization molding in the mold cavity plastifying sizing material, so is provided with running gate system in the mould.Plastified sizing material and be injected in the mold cavity by running gate system, and then sulfidization molding.The General Purpose Rubber injecting molding die is that the vulcanizate after the die sinking in the running gate system becomes waste material and thrown away with the sizing material in the running gate system and the sizing material in die cavity baking together during sulfidization molding.Capital of every injection produces some waste materials, the waste material amount that per injection produced is relevant with the die cavity number, monotype cavity mould for the big product of moulding, it is less that the waste material amount that produces accounts for the ratio of product materials amount, but for the multi-imprssion mould tool of the little product of moulding, the waste material amount of generation accounts for the large percentage of product materials amount.Especially moulding needs the high accuracy small piece of many cast gate injections, and except that being provided with the runner by the die cavity number, each die cavity also needs to set up runner in addition again by the cast gate number, so the runner number increases.The result is that the waste material that every injection is once produced is multiplied, and has caused raw-material very big waste.Except that causing waste of raw materials, the sizing material in the runner has also consumed sizable a part of heat energy in high temperature vulcanized process.In addition, get waste material and need manually finish, labor strength is big.Waste material is got in die sinking needs bigger opening stroke and more die sinking time, has therefore also caused the prolongation of molding cycle, has influenced production efficiency.
Summary of the invention:
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, design provides the cold runner injection molding of rubber mould of a kind of a multi-cavity mold, the many cast gates in a chamber, be used for high yield, the small-sized rubber part of high-quality moulding, to solve the defective that existing General Purpose Rubber injecting molding die exists.
To achieve these goals, but the cold runner injection molding of rubber mould that the utility model relates to comprises dynamic model, die cavity, cover half, thermocouple, electric heater, heating plate, nozzle overcoat, longitudinal groove, nozzle body, stepped hole floating nozzle, thermal hole, thermal insulation board, upper reaches guidance tape, dirty guidance tape, groove, straight hole and the air gap, heating plate is installed above the cover half, thermal insulation board is installed between heating plate and the cold flow guidance tape, combined nozzle is installed in below the cold flow guidance tape, is provided with the air gap between combined nozzle and the heating plate; The cold flow guidance tape is made up of upper reaches guidance tape and dirty guidance tape, and the groove on plane constitutes the ground floor runner on the groove of upper reaches guidance tape lower plane and the dirty guidance tape; The upper surface of combined nozzle has the groove that distributes radially more than two, and the groove corresponding with cold flow guidance tape lower plane constitutes second layer runner; But combined nozzle comprises nozzle body, nozzle overcoat and floating nozzle, and nozzle body is provided with plural stepped hole, but a floating nozzle is installed in each stepped hole; The cold flow guidance tape is provided with the thermal hole of circulation medium; Combined nozzle is provided with the longitudinal groove of circulation heat-conducting medium, and longitudinal groove communicates with cold flow guidance tape thermal hole.
The utility model carries out temperature control to the sizing material in die cavity and the runner respectively by heating plate and cold flow guidance tape.Between curing time, heating plate carries out the high temperature heating to the sizing material in the die cavity, make its sulfidization molding, meanwhile, the cold flow guidance tape is controlled at the sizing material in the runner below the curing temperature, and it is remained under the flowable state, only takes out product during die sinking, sizing material in the runner still is retained in the runner, and these sizing materials are injected into die cavity and are sulfided into product when injecting next time.No waste material produces in whole forming process, and the heat energy that sizing material consumes in the runner also seldom.Therefore the utility model compared with prior art not only can carry out high yield, the high quality of production of little product, but also can economize in raw materials and the energy, enhances productivity, and alleviates labor strength.
