Compared with prior art, the utility model has the advantage of:
1. runner and injection orifice arranged outside have heater, in injection moulding, the plastics in runner and in injection orifice are heated always, keep its molten condition, can not produce cooling waste material, provide cost savings; Heater is connected with intelligent temperature control module, has protected heater in suitable temperature range, has avoided plastics to cross the quality of heat affecting plastic product; Heater is resistor ceramic, and heating effect is good.
2. wear by sealing face is changed into wiping by original breaking, solved the problem of runner burr, also saved the raw material of product simultaneously, improved the stability of product quality.
3. owing to being provided with pressure sensor in injection mold, just can utilize pressure sensor monitoring plastics in injection molding, mold filling, pressurize and cooling procedure from the filling mouth of injection machine to the plastic pressure die cavity, and then carry out corresponding parameter adjustment, ensure shaped article quality.
4. by being designed to by filling with mouth sprue the structure that epimere diameter is less than hypomere diameter, when injector mouth portion is when filling with in mouth material feeding, can effectively avoid the flash phenomenon of injector mouth portion, avoid the waste of raw material.
5. in prior art, go out the mould of two (a secondary mould can produce two products in single injection-molded) for one, when for some special object or require to need one to go out for the moment, common way is to adopt plug or one of them runner communicating with forming cavity of bearing pin shutoff, but when needs recover one while going out two, dismantle more difficultly, also have the poor problem of shutoff fastness simultaneously.The T-slot of the utility model on inserting by rotation, can realize very easily one and go out one or one and go out 2 two kinds of mode depannings.
