Abstract

The invention discloses a guide piece, a hot nozzle module and a hot runner system. The guide piece comprises a main body; the main body is provided with a main body center line; a runner for enablinga colloid to pass through is formed in the main body; the runner is provided with an inlet and an outlet; and on a plane perpendicular to the center line, a projection center point of the inlet is spaced from a projection center point of the outlet by a certain distance. The colloid can be rotated around the center line of the main body after flowing out from the runner of the guide piece; and through rotation of the colloid, the colloid can be mixed more uniformly. In particular, if some deteriorated colloids exist in the hot nozzle channel, the deteriorated colloids are mixed with new colloids in the rotating process, and cannot be agglomerated in one place to relieve or even prevent such bad conditions as obvious mixed colors and yellowing in finished injection products, and in particular, the improvement effect on white and transparent products is better.

Description

technical field [0001] The invention relates to a flow guide for a hot runner system, a hot nozzle assembly and a hot runner system. It belongs to the field of injection molding. Background technique [0002] A hot nozzle assembly in a traditional hot runner system includes a hot nozzle body, a nozzle tip partially located in the hot nozzle body, and a pressure cap arranged between the hot nozzle body and the nozzle tip. There is a hot nozzle channel on the hot nozzle body, and a nozzle tip channel on the tip of the nozzle. The hot nozzle channel and the nozzle tip channel are connected. The colloid flows from the hot nozzle channel into the nozzle tip channel, and finally realizes the injection molding function. [0003] In the prior art, the resin has accumulated in the channel for a long time, and the hot nozzle is in a heated state for a long time. The resin on the channel wall of the hot nozzle will change in texture after a long time, such as white material, which wil...
