Abstract
An inner-spring nozzle is disclosed. The nozzle comprises a subsidiary nozzle, a nozzle middle body and a nozzle flange. The tail of the nozzle middle body is connected to the nozzle flange and the head of the nozzle middle body is connected to the subsidiary nozzle. The middle of the nozzle middle body is provided with a pressure spring. By setting the pressure spring in the nozzle middle body, plastic in a melt state enters the nozzle middle body, and when the injection pressure is larger than the pressure of the pressure spring, the plastic in the melt state pushes a sealing compound valve core backward to separate the front-end angle of the sealing compound valve core from an inner-hole angle of the subsidiary nozzle so as to generate a gap, so that the plastic in the melt state enters a mold successfully to form a product. When the injection pressure is smaller than the pressure of the pressure spring, the spring pushes the sealing compound valve core frontward to allow the thrust angle of the sealing compound valve core and the inner-hole angle of the subsidiary nozzle to be matched precisely, so that the plastic in the melt state cannot flow out from a feeding pipe of the subsidiary nozzle, thus preventing plastic backflow, avoiding a problem of cold charge generation, increasing the production efficiency of plastic injection molding products and improving product quality of plastic injection molding products.
