Abstract
The utility model relates to an injection molding machine head with a constant temperature control mechanism, which comprises a nozzle, wherein the tail end of the nozzle is connected with a flange plate; the injection molding machine head is fixed in a working area of an injection molding machine through the flange plate; an outer lock sleeve is sleeved on the periphery of the front part of the nozzle and is fastened through a first bolt; a heating ring is arranged in the outer lock sleeve and is electrically connected with a constant temperature controller; a heating lock sleeve is sleeved on the periphery of the rear part of the nozzle and is fastened through a second bolt; and a heater is arranged at the outer part of the heating lock sleeve and is electrically connected with a motor of the injection molding machine. According to the utility model, the raw material in the nozzle is subjected to sectional control and is directly heated by the heater; and when the raw material inside passes through the head part of the nozzle, the temperature of the raw material jetted out of the nozzle head is controlled by the constant temperature controller so as to achieve the aim of sectional and constant temperature control, guarantee the temperature requirement of the raw material injected into a die and improve the quality of an injection molding workpiece.
Description
Technical field:
The utility model relates to the injection moulding head, relates in particular to a kind of injection moulding head with thermostatic control mechanism to injection moulding head segmentation control temperature.
Background technology:
The injection moulding head is mounted on the injection machine, through with original graininess plastic raw materials through the fusion of fusion machine after, behind the spray chamber in the injection moulding head; Be injected in the mould by nozzle head; Finalize the design after the cooling, obtaining us needs injection molding plastic product, when the raw material of molten condition gets into the spray chamber of nozzle; To its temperature is to have necessarily requiredly, and guaranteeing that raw material can not solidify in spray chamber freezes.
Like this, just need add one deck heat preservation mechanism in the outside of nozzle, original structure is to add one deck heating lock tube in the outside of nozzle; In this heating lock tube, be provided with heating collar, through generating on the motor it carried out continual heating, like this; Having caused the raw material shakiness in the spray chamber is constantly to rise; Be easy to the outside that will after-tack the injection moulding head again from the high temperature raw material of nozzle ejection, influence its service life, also the quality to the injection moulding workpiece affects.
Summary of the invention:
The technical problem that the utility model solves provides a kind of injection moulding head with thermostatic control mechanism, and the temperature of raw material guarantees to fix from the material temperature that nozzle goes out to penetrate in the employing segmented control spray chamber, the quality of workpiece after the raising injection mo(u)lding.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of injection moulding head with thermostatic control mechanism; Comprise nozzle, the tail end of this nozzle is connected on the ring flange, this injection moulding head is fixed to the working region of injection machine through ring flange; Lock tube outside the anterior periphery sheathed of said nozzle; Should pass through first bolted by outer lock tube, and outside this, be provided with a circle heating circle in the lock tube, this heating is enclosed and is electrically connected a radiator valve; The sheathed heating lock tube of periphery at the rear portion of said nozzle, this heating lock tube is provided with a heater through second bolted in the outside of this heating lock tube, and this heater is electrically connected on the motor of injection machine.
Further; In order to guarantee that the material temperature after the rear portion heating is entering into nozzle when anterior, temperature can not be lower than the temperature of designing requirement, in said heating lock tube, is provided with a collar; The inside of this collar offers internal thread; This collar is set in the external screw thread place of nozzle, and the effect one of this collar is the effect of playing insulation, and the 2nd, nozzle is played fastening effect.
The beneficial effect of this device: this device is to the processing of heating of the liquid in the nozzle; The control of employing segmented is directly heated it by heater, when inner raw material passes through the head of nozzle; Control the material temperature that comes out from nozzle head through the radiator valve that electrically connects with heating circle; Reach segmentation and thermostatically controlled purpose, guarantee to inject the temperature requirement of raw material in the mould, improve the quality of its injection moulding workpiece.。
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further specified.
Sketch map when Fig. 1 is the utility model assembly;
Fig. 2 is the sketch map of the utility model China and foreign countries lock tube;
Fig. 3 is the stereogram of the utility model.
Among the figure: 1, nozzle 2, ring flange 3, outer lock tube 4, first bolt 5, heating circle 6, heating lock tube 7, second bolt 8, heater 9, the collar.
The specific embodiment:
Like Fig. 1-a kind of injection moulding head shown in Figure 3 with thermostatic control mechanism; Comprise nozzle 1, the tail end of this nozzle 1 is connected on the ring flange 2, this injection moulding head is fixed to the working region of injection machine through ring flange 2; Lock tube 3 outside the anterior periphery sheathed of said nozzle 1; It is fastening through first bolt 4 to be somebody's turn to do outer lock tube 3, outside this, is provided with a circle heating circle 5 in the lock tube 3, and this circle 5 that generates heat electrically connects radiator valves (not shown); This radiator valve is arranged on a side of this engine housing of injection machine, makes things convenient for the manual work to control temperature at any time; The sheathed heating lock tube 6 of periphery at the rear portion of said nozzle 1, this heating lock tube 6 is fastening through second bolt 7, is provided with a heater 8 in the outside of this heating lock tube 6, and this heater 8 is electrically connected on the motor of injection machine.
Further, entering into nozzle when anterior in order to guarantee the material temperature after the rear portion heating, temperature can not be lower than the temperature of designing requirement; In said heating lock tube 6, be provided with a collar 9; The inside of this collar 9 offers internal thread, and this collar 9 is set in the external screw thread place of nozzle, adopts the screw thread socket; The one, play the effect of insulation, the 2nd, nozzle is played fastening effect.
This device is to the processing of heating of the liquid in the nozzle; Employing segmented control is directly heated it by heater 8, during the head of inner raw material through nozzle 1; Control the material temperature that comes out from nozzle head through the radiator valve that electrically connects with heating circle 5; Reach segmentation and thermostatically controlled purpose, guarantee to inject the temperature requirement of raw material in the mould, improve the quality of its injection moulding workpiece.
It is emphasized that; More than be the preferable enforcement row of the utility model; Be not that the utility model is done any type of restriction in appearance; Every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did.
