Problems solved by technology

[0002] Hot runner nozzles are used in injection molds. With the development of injection molds, hot runners have been widely used in injection molds. Hot runner nozzles are an indispensable and important part of hot runners. The new nozzles with this point gate structure are The new structure is improved on the basis of the existing technology. The new structure is mainly to improve the following existing technologies: 1. The surface requirements of plastic products are extremely high, and the existing point gate structure is used. There are large gate marks, and there are 3 impact marks on the surface of the molded product. The nozzle is cut too much, and the product turns yellow.

Abstract

The invention discloses a single-hole type mouth core pin-point gate hot runner nozzle which comprises a mouth core and a sprue bush which are coaxially arranged inside one end of a nozzle body in a sleeving manner, wherein one end of the mouth core is embedded in the nozzle body, and the other end of the mouth core is a conical end; the bottom of the conical end is encircled by the sprue bush; a first runner is formed in the nozzle main body; a second runner is formed in the mouth core; the second runner is communicated with the first runner; a runner hole is formed in a conical surface of the conical end and is communicated with the second runner; and an acute included angle is formed between the axis of the runner hole and the axis of the second runner. According to the hot runner nozzle disclosed by the invention, a combined structure is adopted, a single round hole having a certain angle with the runner hole of the nozzle main body is formed after the matching of the nozzle main body and the sprue bush, a small gate mark is reserved on the surface of a molded product, the condition that three percussion marks are on the surface of the product is avoided, the amount of shearing heat of the nozzle is small, the yellowing risk of the product is reduced, and an excellent sprue appearance can be achieved.
