Abstract

The invention discloses a nozzle structure for injection blowing. The nozzle structure comprises a hot-runner plate and a nozzle pressing plate, wherein the hot-runner plate is arranged on a runner backing plate, the nozzle pressing plate is connected with the hot-runner plate, a nozzle is arranged in the nozzle pressing plate, a heating device sleeves the periphery of the nozzle, an insulation pad sleeves the discharge end of the nozzle, the discharge end of the nozzle extends into an injection molding cavity of a forming die, and a forming core rod is arranged in the injection molding cavity. By using the nozzle structure for injection blowing, the temperature of the bottom of a pipe blank is easy to control.

Description

technical field [0001] The invention relates to an injection blowing machine, in particular to a nozzle structure for injection blowing. Background technique [0002] Conventional injection and blowing nozzles include a hot runner plate arranged on the runner backing plate, and a nozzle pressure plate connected to the hot runner plate. A nozzle is arranged in the nozzle pressure plate, and the discharge end of the nozzle extends into the injection mold of the molding mold. In the mold cavity, a molding mandrel is arranged in the injection mold cavity. With this conventional structure, the nozzle is directly in contact with the injection mold cavity, and the nozzle is not temperature controlled, which makes the nozzle easy to block, and the temperature at the bottom of the injection molded tube is difficult to control, resulting in uneven thickness at the bottom of the product, making it difficult to produce qualified products. The product. Contents of the invention [00...
