Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but should not be construed as a limitation of the present invention.

The embodiments of the present invention will be described below according to the overall structure of the present invention.

A short nozzle injection mold structure, as shown in Figures 1-3, includes a panel 1, a nozzle plate 2 is arranged at the bottom of the panel 1, and an upper template 4 is arranged at the bottom of the nozzle plate 2, and the middle of the upper template 4 is close to the nozzle plate 2. The bottom is provided with a nozzle plate 3, the nozzle plate 2 and the nozzle plate 3 are used to guide the plastic liquid, the lower part of the center of the nozzle plate 3 is provided with an organic nozzle 7 for instilling the plastic liquid, and a lower template 11 is arranged under the upper template 4, and An upper mold 5 is arranged between the upper mold plate 4 and the lower mold plate 11. The upper mold plate 4, the lower mold plate 11 and the upper mold 5 are combined into a mold for injection molding. The upper mold 5 is provided with a flow channel 8, and the upper mold 5 is provided with a Through the glue port 10 of the upper mold 5 and the flow channel 8, the flow channel 8 can evenly introduce the plastic liquid into the glue port 10.
