Abstract
The utility model discloses an improved structure of a spray nozzle of an injection molding machine, which comprises a sprayer body and a sprayer passageway arranged in the sprayer body and communicated with two ends of the sprayer body, wherein a threaded connection part is arranged on the outer surface of the rear end of the sprayer body, a nozzle is arranged at the front end of the sprayer body, the nozzle is communicated with the sprayer passageway through a discharging passage, and a heating device is arranged between the nozzle and the threaded connection part on the periphery of the sprayer body. The heating device comprises a heating coil, and the heating coil is connected with a high-frequency inductive heater. The sprayer is provided with the heating coil, therefore, when in use, the high-frequency inductive heater enables the coil to generate an alternating magnetic field, eddy current is generated and magnetic hysteresis loss is caused in the sprayer, the generated heat increases the temperature of the sprayer, and the power of the high-frequency inductive heater is adjusted, thus being capable of controlling the temperature rise of the sprayer. Therefore, the temperature can be adjusted according to melting condition of raw material in the sprayer, thus maintaining the melted material in the sprayer in an appropriate state, and guaranteeing the forming quality.
Description
Technical field
The utility model relates to a kind of injection machine shower nozzle structure-improved.
Background technology
The course of work of injection machine is, at first granular or powdered plastic are added in the machine barrel, and the rotation by screw rod and the heating of machine barrel outer wall make plastics become molten condition, machine carries out matched moulds and injection seat reach then, make nozzle be adjacent to the pouring head of mould, then to the logical people's pressure oil of injection cylinder, screw rod is pushed ahead, thereby in very high pressure and the fast speeds close die that the melt implantation temperature is lower, keep, cool off through certain hour and pressure, make its curing molding, but just goods are taken out in die sinking.Machine barrel outer wall heating back can stay for some time at shower nozzle to finally injecting the mould fused raw material from shower nozzle, thereby temperature can reduce, and has influenced Forming Quality.
The utility model content
Technical problem to be solved in the utility model just provides fused raw material temperature in a kind of maintenance shower nozzle, guarantees the injection machine shower nozzle structure-improved of Forming Quality.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of injection machine shower nozzle structure-improved, comprise head body, be arranged on the shower nozzle runner that head body is inner and communicate with the head body two ends, the head body back end outer surface is provided with threaded joints, the head body front end is provided with nozzle, is communicated with by tapping channel between described nozzle and shower nozzle runner, and it is characterized in that: described head body excircle is provided with heater between nozzle and threaded joints.
As preferably, described heater comprises heater coil, and described heater coil connects high frequency induction heater.
The utility model is because shower nozzle is provided with heater coil, in use, high frequency induction heater makes coil send alternating magnetic field, make and produce vortex flow, magnetic hystersis loss in the shower nozzle, the heat that is produced rises nozzle temperature, by regulating the power of high frequency induction heater, can control the temperature rise of shower nozzle.Thereby, can adjust temperature according to melting raw materials situation in the shower nozzle, make the interior fused raw material of shower nozzle remain on proper state, guarantee Forming Quality.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, be the structure improved embodiment of a kind of injection machine shower nozzle of the utility model, comprise head body 1, be arranged on the shower nozzle runner 2 that head body is inner and communicate with the head body two ends, head body 1 back end outer surface is provided with threaded joints 3, head body 1 front end is provided with nozzle 4, is communicated with by tapping channel 5 between described nozzle and shower nozzle runner, and described head body excircle is provided with heater between nozzle and threaded joints.Described heater comprises heater coil 6, and described heater coil connects high frequency induction heater 7.
