Abstract
The utility model discloses a regulating mechanism of a hot runner nozzle valve needle, which comprises a nozzle and a gas cylinder, wherein the nozzle is fixed on a fixed plate, a feeding port of the nozzle is communicated with a main sprue of an injection molding machine, a valve needle is connected in a nozzle runner inside the nozzle in a sliding manner, the gas cylinder is fixed on the fixed plate, the gas cylinder is arranged at one side of the nozzle, an upright column fixed on the fixed plate is arranged between the gas cylinder and the nozzle, the top end of the upright column is connected with a connecting rod in a rotatable manner, and the two ends of the connecting rod are respectively connected to the gas cylinder and the valve needle in a rotatable manner. A circulating water cooling device is arranged in the fixed plate. A water circulating system is arranged in the cylinder body of the gas cylinder. As the gas cylinder and the nozzle are not on the same axis, the valve needle in the nozzle is regulated up and down by the gas cylinder through the connecting rod. Under the condition that the flow rate of a spray opening of the nozzle is accurately controlled by the gas cylinder, the main sprue of the injection molding machine and the feeding port of the nozzle can be on the same axis. Through the circulating water cooling device and the water circulating system, the high-temperature heat of the nozzle is prevented from being conducted to the gas cylinder.
Description

The specific embodiment
As shown in Figure 1, the utility model discloses a kind of hot-runner nozzle needle governor motion, comprise nozzle 1 and cylinder 4, described nozzle 1 is fixed on the fixed head 5, described nozzle 1 is fixed on the below of fixed head 5 usually, its charging aperture 6 up, the charging aperture 6 of described nozzle 1 is connected with injection machine master cast gate 7, has nozzle flow channel 2 in the described nozzle 1, slidely connect a needle 3 in the described nozzle flow channel 2, in actual applications, for guaranteeing the flowability of injection molding material in nozzle flow channel 2 and injection machine master cast gate 7, usually need winding heater coil 12 outside nozzle 1 and injection machine master cast gate 7, described cylinder 4 also can adopt oil cylinder in actual applications.
Innovative point of the present utility model is that mainly described cylinder 4 is fixed on the fixed head 5, described cylinder 4 must be fixed on the top of fixed head 5, described cylinder 4 is positioned at nozzle 1 one sides, be exactly specifically described cylinder 4 and the position of nozzle 1 on fixed head 5 at intervals; Be provided with a column 8 that is fixed on the fixed head 5 between described cylinder 4 and the nozzle 1, the top of described column 8 connecting rod 9 that has been rotatably connected, specifically, the top of the column 8 that the middle part of described connection 9 is rotatably connected; Two ends of described connecting rod 9 are rotatably connected respectively on cylinder 4 and needle 3, and specifically, an end of described connecting rod 9 and the flexible cylinder of cylinder 4 are rotatably connected, and the top of the other end of described connecting rod 9 and needle 3 is rotatably connected.Like this, when the flexible cylinder of cylinder 4 extends, the end that drivening rod 9 is rotatably connected with it rises, and utilizes lever principle, and connection 9 descends with the end that needle 3 is rotatably connected, driving needle 3 slides to lower edge nozzle flow channel 2, needle 3 is in the process of lower slider, and the spout 13 of nozzle 1 is closed gradually, is shut by needle 3 fully until spout 13, injection molding material reduces gradually at the flow of spout 13, until being zero.When the flexible cylinder of cylinder 4 is withdrawn, the end that drivening rod 9 is rotatably connected with it descends, utilize lever principle, connection 9 is risen with the end that needle 3 is rotatably connected, drive needle 3 and slide to upper edge nozzle flow channel 2, needle 3 is in the process of upwards sliding, and the spout 13 of nozzle 1 strengthens gradually, until spout 13 standard-sized sheets, injection molding material increases gradually at the flow of spout 13.
Because in injection moulding process, the 12 pairs of nozzles 1 of heater coil and the injection machine master cast gate 7 of nozzle 1 and the 7 outer windings of injection machine master cast gate are heated, for the heat that prevents nozzle 1 and injection machine master cast gate 7 is transmitted on the cylinder 4, cylinder 4 is heated up and influence the operate as normal of cylinder 4, for this reason, be provided with in the described fixed head 5 of hot-runner nozzle needle governor motion of the present utility model in the cylinder body of circulating water cooling device 10, described cylinder 4 and be provided with water circulation system 11.Can reduce the temperature of fixed head 5 by circulating water cooling device 10, make the heat of nozzle 1 and injection machine master cast gate 7 be difficult for being transmitted on the cylinder 4, simultaneously, the cooling that realizes cylinder 4 by water circulation system 11.
