AI Technical Summary

Technical Problem

Existing technologies make it difficult to directly inject multiple product cavities within a mold with limited space, resulting in a high rate of product appearance defects, large positioning errors, and easy material leakage, especially for thin tube shapes or products with rotatable multi-point ingates.

Method used

A side-injection hot nozzle with convenient positioning was designed. It adopts a nozzle rod, nozzle body and nozzle core structure. The nozzle tip is accurately positioned by sliding connection between nozzle core and nozzle body and radial limiting component. Combined with copper sleeve to control temperature, anti-cavity groove to ensure connection stability, nozzle tip limiting groove and limiting block for multi-directional positioning, simplifying installation and maintenance.

Benefits of technology

It enables precise injection molding in confined spaces, improves product dimensional accuracy, reduces the risk of material leakage, simplifies the installation and maintenance of hot nozzles, and reduces costs.

Abstract

This invention provides a side-injection hot nozzle for convenient positioning, comprising a nozzle rod, a nozzle body, and a nozzle tip. The nozzle rod is connected to the nozzle body. A nozzle core, slidably connected to the nozzle body, is located in the middle of the nozzle body. The nozzle core includes a conical radial limiting member. A rear cover is located at the end of the nozzle body, connecting to the nozzle body and limiting the nozzle core within the nozzle body. The nozzle body has a nozzle tip limiting groove through which the nozzle tip extends into the nozzle body and contacts the sidewall of the radial limiting member. The nozzle rod has a first flow channel, the nozzle core has a second flow channel, and the nozzle tip has a third flow channel. The first flow channel communicates with the second flow channel, and the second flow channel communicates with the third flow channel. Using the technical solution of this invention, injection molding in confined spaces is achieved with precise positioning, resulting in products with high dimensional accuracy and aesthetic appearance. Furthermore, the structure is simple, installation and use are convenient, and costs are reduced.
