Problems solved by technology

In the production process of the all-plastic thread protector, due to the single nozzle channel of the existing injection molding machine, the speed of the injected molten plastic is high and the impact is large, so that the output is not easy to control, and overflow often occurs during injection molding.

Abstract

The invention discloses a multi-channel injection molding nozzle for a fully plastic thread protector. The molding nozzle is used for an injection molding device for processing a thread protector of a steel pipe head. The molding nozzle comprises an ejector and an injection nozzle at the end of the ejector. The middles of the ejector and the injection nozzle form a through injection chamber. A material cavity is arranged between the injection chamber of the ejector and the outer wall of the ejector. A number of channels passing through the injection chamber are arranged in the material cavity. Through use of the channels, molten plastic enters the injection chamber through the channels so that the nozzle injection speed is uniform and injection molding pressure is stable.

Description

technical field [0001] The invention is an injection molding device used for processing a thread protector of a steel pipe head. Background technique [0002] The injection molding machine is the main molding equipment for making thermoplastic or thermosetting materials into various shapes of plastic products using plastic molding molds. It can heat the plastic and apply high pressure to the molten plastic to make it shoot out and fill the mold cavity. In the production process of the all-plastic thread protector, due to the single nozzle channel of the existing injection molding machine, the speed of the injected molten plastic is high and the impact force is large, so that the output is not easy to control, and overflow often occurs during injection molding. Contents of the invention [0003] The invention provides a multi-channel injection molding nozzle for an all-plastic thread protector, which has uniform spraying speed and stable injection molding pressure.
