Abstract
The embodiment of the utility model discloses mouth is chewed to constant temperature heat, including the base, chew the core, chew the head, the heat preservation overcoat, chew core fixed mounting in on the base, chewing in the core periphery closely, the winding has the electrical heating circle, chew first fixed mounting in chew the end of core, the heat preservation overcoat will chew the core cover in it and fixed mounting in on the base. Adopt the utility model discloses, through setting up electric heating wire chewing the core periphery to through the temperature sensor real time control temperature, reach the homothermal requirement of colloid, and have good soffening, avoided injection moulding product the flaw to appear, improved the production quality of product.
Description
Technical field
The utility model relates to a kind of injection moulded fittings, particularly relates to a kind of constant temp. heating nozzle mouth.
Background technology
At present, the main injection mold using cold runner structure form of injection mo(u)lding processing is main, and for the injection mold of hot runner structure form, cold runner structure exists molding cycle length, poor product quality and wastes raw-material defect；In order to overcome the defect existing for traditional cold runner structure, the most expanded application of hot runner structure, the most existing many companies produce TOP-TIP.Hot runner mould is to utilize heater to make the most noncondensing mould of melt in runner.Hot mouth is one of critical component of hot runner mould, the quality of the goods that the quality of hot mouth performance directly affects.Do not require nothing more than, during the work of hot mouth, the die cavity ensureing that sizing material enters hot runner mould smoothly, it is necessary in ensureing hot mouth, sizing material is in the molten condition under uniform temperature, and existing hot nozzle mouth is often due to runner non-uniform temperature, causes product impression occur or there is flaw.
Summary of the invention
The utility model embodiment technical problem to be solved is, it is provided that a kind of constant temp. heating nozzle mouth.Can flow out by the sizing material constant temperature in runner, it is ensured that the quality of product.
In order to solve above-mentioned technical problem, the utility model embodiment provides a kind of constant temp. heating nozzle mouth, including pedestal, nozzle core, nozzle head, thermal-insulation coat, described nozzle core is fixedly installed on described pedestal, Electrothermal ring closely it is wound with on described nozzle core periphery, described nozzle head is fixedly installed in the end of described nozzle core, and described nozzle core retainer plate in the inner and is fixedly installed on described pedestal by described thermal-insulation coat.
Further, there is between described nozzle core, nozzle head the runner that some axial symmetry are arranged.
Further, described runner is three.
Further, described nozzle head is pinnacle of a pagoda shape.
Further, described pedestal arranging electric connection, described Electrothermal ring connects power supply through described electric connection.
Further, described Electrothermal ring is provided with temperature sensor by described electric connection.
Implement the utility model embodiment, have the advantages that the utility model, by arranging electrical heating wire in nozzle core periphery, and controls temperature by temperature sensor in real time, reach the requirement of colloid constant temperature, avoid injecting products and flaw occurs, improve the quality of production of product.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the internal structure schematic diagram that the utility model removes thermal-insulation coat.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to the structural representation shown in Fig. 1, Fig. 2.
A kind of constant temp. heating nozzle mouth of the utility model embodiment, including pedestal 10, nozzle core 20, nozzle head 30, thermal-insulation coat 40.
Nozzle core 20 is fixedly installed on pedestal 10, nozzle head 30 is fixedly installed in the end of nozzle core 20, the periphery of nozzle core 20 is closely wound with Electrothermal ring 21, nozzle core 20, Electrothermal ring 21 are overlapped in the inner by thermal-insulation coat 40, and fixing being installed on pedestal, conduct on nozzle core 20 with making the even heat that Electrothermal ring 21 sends.
More excellent, thermal-insulation coat 40 is connected on nozzle core 20 by jump ring.
Nozzle head 30, in pinnacle of a pagoda shape, is provided with some axisymmetric runners 31 between itself and nozzle core 20, be three at the preferred runner of the present embodiment, and the end outlet of runner 31 is positioned on the wall of pinnacle of a pagoda.
Arranging electric connection 11 on pedestal 10, Electrothermal ring 21 is provided with temperature sensor by electric connection 11 external power supply, Electrothermal ring by 21 electric connections 11, nozzle core 20 is made to control at temperature constant state, plastic cement high temperature is avoided to burn black, it is ensured that plasticizing good fluidity, plastic rubber shaping Functionality, quality and appealing design.
Certainly above-described embodiment is only for illustrating technology of the present utility model design and feature, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All modifications done according to the Spirit Essence of the utility model main technical schemes, all should contain within protection domain of the present utility model.
Claims (5)
1. a constant temp. heating nozzle mouth, it is characterized in that, including pedestal, nozzle core, nozzle head, thermal-insulation coat, described nozzle core is fixedly installed on described pedestal, Electrothermal ring closely it is wound with on described nozzle core periphery, described nozzle head is fixedly installed in the end of described nozzle core, and described nozzle core retainer plate in the inner and is fixedly installed on described pedestal by described thermal-insulation coat, has the runner that some axial symmetry are arranged between described nozzle core, nozzle head.
