[0002] Injection molding industry occupies an important position in modern manufacturing. In 2024, the injection molding industry continues to develop, providing key components and products for many fields. From automobile manufacturing to electronic equipment, from daily necessities to medical devices, injection molding products are everywhere. By injecting molten plastic into a mold, it quickly forms various complex shapes and high-precision products. With continuous technological progress, the injection molding industry is constantly striving to improve production efficiency, reduce costs, and improve product quality, while actively exploring new environmentally friendly materials and sustainable production methods to meet market demand and environmental requirements.

[0003] In current industrial and production application scenarios, we found that the existing nozzle has a more prominent problem, which is unable to automatically exhaust. In actual operation, when the nozzle starts working, the residual air inside often cannot be effectively exhausted. This can cause a series of adverse consequences, such as in the application scenario of liquid injection, the presence of air can disrupt the continuity of liquid injection, resulting in intermittent situations, which seriously affects the uniformity of the injection effect. In some industrial manufacturing processes that require extremely high precision, such as the fine material injection process in electronic chip manufacturing, this unevenness can cause a significant decline in product quality and increase the rate of defective products. Moreover, the retention of air in the nozzle can also cause abnormal pressure fluctuations, negatively affecting the stability of the entire fluid delivery system, shortening the service life of the system, increasing maintenance costs and potential production risks. In addition, in the rapid response injection task, due to the interference of air, the nozzle may take longer to reach a stable injection state, reducing work efficiency and thus restricting the efficient operation of the production process as a whole.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work belong to the range of protection of the utility model.

[0023] Please refer to Figure 1 The utility model provides a kind of technical scheme: a new automatic exhaust nozzle of injection molding machine, it include: feed pipe wall 2, stirring column 6, exhaust gasket 7, exhaust hole 8 and nozzle shell 13, feed pipe wall 2 is connected to the injection port of nozzle shell 13, feed pipe wall 2 is used to play the role of protection feed inner tube 4, also be used to the injection of material cylinder is drained to nozzle shell 13, ensure that subsequent exhaust treatment can be carried out to injection, feed pipe wall 2 is used to be sent to injection to nozzle shell 13, nozzle shell 13 is equipped with stirring column 6, stirring column 6 is cylindrical, the drainage groove 61 of stirring column 6 surface is diamond shape, such design has two benefits, one is can strengthen the contact of exhaust gasket 7, can better exhaust outward, two is that injection can be stirred, prevent the situation of jam when injection, the outside of stirring column 6 and exhaust gasket 7 connect, the number of exhaust gasket 7 is at least two, there is certain gap between all exhaust gasket 7, the size of this gap is smaller than injection, so as to reach injection cannot pass through gap, but air in injection can pass through gap, plus the hydraulic pressure in injection barrel, so as to reach the effect of outward exhaust, stirring column 6 is used for exhaust gasket 7 to exhaust gas in injection into exhaust hole 8, air that is finally discharged outward from gap leaks through exhaust hole 8, not accumulated in injection, discharge outward, exhaust hole 8 is located at the outside of exhaust gasket 7, facilitate air to exclude the outside of nozzle shell 13.

[0024] As Figures 2-3As shown, the output end of the nozzle housing 13 is provided with a distribution pipe 5, which is used to distribute the spray material through the distribution plate 51 to ensure that the spray material can flow to both sides of the stirring column 6, achieving the effect of stirring and exhaust through the drainage groove 61. The distribution plate 51 is at an angle, and the size of the opening of the distribution plate 51 is consistent with the size of the end point of the stirring column 6, ensuring that there is no material storage. The distribution pipe 5 is provided with a distribution plate 51, which is used to distribute the spray material. There is a gap between the exhaust gasket 7 and the stirring column 6, which is the position of the spray material flow, ensuring that the spray material can enter the drainage groove 61, and the drainage groove 61 is present in the gap. The number of exhaust gaskets 7 is at least two, which are stacked and sleeved outside the stirring column 6.

The installed suction machine is controlled by an electric control box and can achieve intermittent adsorption. The gas and liquid are maximized to effectively balance the pressure during injection, ensuring the maximum qualification rate of product forming. The temperature control table (control panel) in the electric control box is composed of multiple groups (according to the size of the product), which adjusts the temperature of the heating device of the nozzle to ensure uniform heating of the heating points and consistent temperature, achieving the best constant temperature state and maximizing the product qualification rate. The time relay and electromagnetic valve in the box are used to control the suction pump and cleaning air gun (which can automatically clean the remaining material by cooperating with the mold opening and closing number of the injection molding machine), and the leakage protection function can cut off the power supply in time when a problem occurs (safety), avoiding accidental losses.
