Abstract

The invention provides a hot runner structure, an injection mold, a machining method and an injection method. The hot runner structure comprises a first hot runner insert, a second hot runner insert, a hot runner plate and a hot nozzle; the second hot runner insert is arranged on the outer side of the first hot runner insert in a sleeving manner, the outer wall of the first hot inner inset and / or the inner wall of the second hot runner insert are / is provided with a spiral groove which serves as a first hot runner, a second hot runner is arranged on the hot runner plate, and the second hot runner is connected with one end of the first hot runner; a third hot runner is arranged on the hot nozzle, one end of the third hot runner and the other end of the first hot runner are connected, and the other end of the third hot runner serves as a hot nozzle sprue. The first spiral hot runner is arranged, and therefore in the injection process, no dead corners exist in the hot runners, and encapsulation air trapping is avoided.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a hot runner structure, an injection mold, a processing method and an injection molding method. Background technique [0002] At present, in related technologies, products molded through injection molds with hot runners tend to have surface defects such as black lines, yellow lines, or impurities on the surface of the product, which seriously affects the surface quality of the product and leads to a decline in the competitiveness of the product. So how to remove the surface defects of products has become an urgent problem to be solved. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] Therefore, the first purpose of the present invention is to provide a hot runner structure. [0005] A second object of the present invention is to propose an injection mold. [0006] A ...
