Description

Technical Field

[0001] The utility model relates to the technical field of heaters, in particular to a half-moon-shaped pouring heater. Background Art

[0002] The hot runner system, originating from the runnerless system used in the injection molding industry, is an advanced plastic injection molding process that uses heating to maintain the molten plastic in the runner and gate. A hot runner system primarily consists of a hot nozzle, a manifold, a temperature control box, and accessories. Hot nozzles typically include open nozzles and needle-valve nozzles. There are two designs for hot runner systems: internally heated and externally heated. In internally heated systems, the heater is located in the center of the runner, while the plastic melt flows through an appropriately sized annular gap. Externally heated systems utilize an annular heating manifold with various insulation features that isolate it from the rest of the mold. This system offers better temperature control, but also comes with higher costs and more complex equipment.

[0003] Heaters play a crucial role in hot runner systems. Existing heaters have various structures, such as one consisting of a coiled spring-shaped heating wire, a sleeve surrounding the wire, and a nozzle body inserted into the wire. To improve heater efficiency, an improved hot runner system heater design has been proposed. This design automatically tightens the nozzle body, eliminating gaps between the heating wire and the nozzle body, allowing heat to be transferred more directly to the nozzle body.

[0004] Within the existing technical framework, the practice of adding heaters to hot runner systems usually relies on a cylindrical heating ring, which is designed to be mounted on the outer wall of the hot runner to achieve the heating function. However, the installation process of this type of heater is relatively complicated, mainly due to its one-piece structural design, which requires it to be fully inserted from the end of the hot runner pipe. This installation step is often subject to multiple constraints of space limitations and the working environment in actual operation, resulting in many difficulties in the installation process. In addition, the internal structure of the heating ring adopts an integrated design, equipped with only a single heating system and thermocouple temperature measurement system. This design improves the simplicity of the system while sacrificing its fault tolerance performance. Once the equipment fails, the entire heating system will face the risk of total failure, which will not only affect production efficiency, but may also cause damage to the hot runner system itself.
