Abstract
A kind of controlling temp type hot nozzle, comprise mouth body, mouth core, mouth, heating circle, its primary structure is that the front end of described mouth body is provided with the mouth core, this mouth core is fixed in the hole of mouth body front end by mouth, on the excircle of mouth body, be provided with an axial groove, front end at the mouth body fixedly is provided with a radial direction through hole in the position of mouth core, this radial direction through hole communicates with axial groove, in axial groove and radial direction through hole, be provided with thermocouple, the bulb of this thermocouple contacts with the mouth core, be provided with the heating circle in the outside of mouth body, be provided with collet in the outside of heating circle, wherein the heating circle connects lead.This nozzle is controlled at being provided with below the temperature value of temperature control instrument to the maximum temperature in the runner by accurately measuring the actual temperature in the runner.
Description
Technical field
The utility model relates to the injection mold field, mainly is meant a kind of thermostatically controlled controlling temp type hot nozzle of hot nozzle of injection mold TOP-TIP.
Background technology
The thermostatic control of the hot nozzle of injection mold TOP-TIP is to guarantee one of key factor of moulding quality.Existing hot nozzle is of a great variety, its shape, structure, mode of heating all have nothing in common with each other, the temperature controlling point of its thermocouple also has nothing in common with each other, the inner or surface that temperature controlling point is set in heater element inside, has that has at the mouth body be provided with temperature controlling point, have at mouth body front end temperature controlling point is set.The setting of these temperature controlling points, its subject matter are the actual temperatures that can not accurately measure in the runner, therefore exist the control temperature not accurate enough, can not accurately control temperature in the runner with temperature control instrument.
Summary of the invention
The purpose of this utility model provides a kind of controlling temp type hot nozzle, and the temperature control point of this hot nozzle is located on the mouth core, therefore can accurately measure the actual temperature in the runner, so effectively overcome the defective that prior art exists.
The realization the technical solution of the utility model is: this controlling temp type hot nozzle comprises mouth body, mouth core, mouth, heating circle, its primary structure is that the front end of described mouth body is provided with the mouth core, this mouth core is fixed in the hole of mouth body front end by mouth, on the excircle of mouth body, be provided with an axial groove, front end at the mouth body fixedly is provided with a radial direction through hole in the position of mouth core, this radial direction through hole communicates with axial groove, is provided with thermocouple in axial groove and radial direction through hole, and the bulb of this thermocouple contacts with the mouth core; Be provided with the heating circle in the outside of mouth body, be provided with collet in the outside of heating circle, wherein the heating circle connects lead.
This technical scheme also comprises:
The radial direction through hole of described mouth body front end is an inclined hole.
Described thermocouple is a line formula thermocouple.
The bulb of described thermocouple contacts with the periphery of mouth core.
The beneficial effect that the utility model had: rational in infrastructure, easy and simple to handle, thermometric accurately, mouth core easy accessibility; Can accurately control the temperature in the runner.
Description of drawings
Fig. 1 is a general structure schematic diagram of the present utility model, wherein 1 charging hole, 2 axial grooves, 3 conductors, 4 mouth bodies, 5 heating circles, 6 collets, 7 mouth cores, 8 thermocouples, 9 radial direction through hole, 10 mouths.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further
As shown in the figure, this controlling temp type hot nozzle is mainly by mouth body 4, heating circle 5, mouth core 7, mouth 10, thermocouple 8 and heat insulating mattress 6; Be charging hole 1 in the middle of the mouth body 4 wherein, its external peripheral surface is provided with an axial groove 2 and radial direction through hole 9, and hole 9 is located at the front portion of mouth body 4, and a mouth core 7 is also installed in this front portion, and mouth core 7 is fixed on the mouth body 4 by the screw thread of mouth 10 and the internal thread of mouth body 4; Line formula thermocouple 8 bulbs one end inserts in the axial groove 2 and radial direction through hole 9 of mouth body 4, and fully contacts with the external peripheral surface of mouth core 7, and its other end is drawn outside the mouth body 4, receives on the temperature control instrument; Heating circle 5 is loaded on mouth body 4 external peripheral surfaces, its bonding conductor 3, and the outside also is with collet 6.This nozzle is owing to directly contact line formula thermocouple 8 bulbs with mouth core 7, thus can accurately measure the interior actual temperature of runner, thus assurance is controlled at being provided with below the temperature value of temperature control instrument to the interior maximum temperature of runner.
