Description

Technical Field

[0001] The utility model relates to the technical field of connector shell injection molding, and more specifically, to an injection molding device for connector shell production. Background Art

[0002] In the prior art, the injection molding device used in the production process of the connector housing usually needs to install a barrel to inject and mold the plastic. However, the existing barrel design has some inconveniences, especially in terms of clamping and disassembly, and the sealing effect before installation.

[0003] First, the design of existing barrels may not be user-friendly, making the clamping and disassembly process cumbersome and time-consuming. This not only increases the labor intensity of operators, but also may affect production efficiency. In a high-speed continuous production environment, any delay in adjusting or replacing equipment may lead to significant production stagnation.

[0004] Secondly, if the barrel cannot be easily disassembled, it also brings difficulties to cleaning and maintenance. The residues in the injection molding process need to be cleaned regularly to prevent blockage and contamination and maintain product quality. The inconvenient disassembly of the barrel may lead to incomplete cleaning, thus affecting the normal operation of the injection molding device and the quality of the injection molded products.

[0005] Furthermore, the poor sealing effect of the existing barrel before installation is also an important problem. Poor sealing may cause leakage of plastic raw materials during the injection molding process, which not only causes waste of raw materials, but also may cause pollution to the working environment. More importantly, poor sealing may cause pressure loss during the injection molding process, thereby affecting the molding quality and precision of the product. Utility Model Content
