Injection molding hot runner system capable of uniformly injecting materials

Abstract

The invention relates to an injection molding hot runner system capable of uniformly injecting materials. According to the solution, in a using process, when the feeding speed is too low, on one hand,a self-adaptive adjustor can play a role in extruding and buffering raw materials, after the raw materials make contact with the self-adaptive adjustor, a motion state can be greatly changed within ashort time, a small range of turbulent flow formed in the fluid-state raw materials is caused, natural sedimentation cannot be formed inside the raw materials, on the other hand, under the action ofthe raw material fluid, a stress block can be pushed to move towards the inner wall of a material conveying pipe to stir the raw materials in the sleeving, the flowing resistance of the raw materialsin the material conveying pipe is increased, the raw materials are not prone to forming the natural sedimentation inside the material conveying pipe, the raw materials are easily kept in a homogeneousstate, meanwhile, the raw materials can be subjected to heat preservation and heating through an electric heating rod installed inside a movable rod so that the relatively stable and homogeneous state of the raw materials can be kept for a longer time before the raw materials are injected into a mold to be molded.

Description

technical field [0001] The invention relates to a uniform injection molding hot runner system, in particular to a uniform injection molding hot runner system. Background technique [0002] The hot runner is to ensure that the plastic in the runner and the gate remains in a molten state by heating. The hot runner system generally consists of several parts such as a hot nozzle, a manifold, a temperature control box and accessories. The hot nozzle generally includes two types: open type Hot nozzles and needle valve hot nozzles, because the form of hot nozzles directly determines the selection of hot runner systems and the manufacture of molds, the hot runner systems are often divided into open hot runner systems and needle valve hot runner systems accordingly. [0003] Compared with traditional injection molding, hot runner injection molds have the advantages of short molding cycle, saving plastic raw materials, improving product quality, facilitating production automation and ...

Problems solved by technology

[0003] Compared with traditional injection molding, hot runner injection molds have the advantages of short molding cycle, saving plastic raw materials, improving product quality, facilitating production automation and expanding the scope of applications. Although compared with traditional injection molding processes, injection molding for hot runner systems The device is more complicated, the cost is higher, and the maintenance is difficult. However, in the production of large products and complex structure products, the hot runner Zusu mold has the advantages that the traditional cold runner mold cannot match

[0004] The injection molding raw material can maintain a relatively stable temperature for a long time in the hot runner system, so that the raw material can maintain a relatively stable and homogeneous shape for a long time before being injected into the mold, which can effectively increase the molding effect of the mold. When the injection process of the hot runner system cannot be uniform, the above characteristics will not be guaranteed. Uneven injection can easily lead to unstable temperature of each part of the raw material, which will lead to the inability of the raw material to be in a homogeneous state, which will easily affect the molding effect of the injection molding product.
