Abstract
An embodiment change core module of an injection mold for a hydrogen tank liner that is injection molded is provided. The change core module includes upper and lower change cores configured to hold a sealless nozzle inside the injection mold, wherein the injection mold comprises upper and lower molds, and wherein the sealless nozzle has a first temperature, and an induction heating device configured to inductively heat the sealless nozzle to a second temperature.
Claims20
A change core module of an injection mold for a hydrogen tank liner that is injection molded, the change core module comprising:
- upper and lower change cores configured to hold a sealless nozzle inside an injection mold, wherein the injection mold comprises upper and lower molds, and wherein the sealless nozzle has a first temperature;
- and
- an induction heating device configured to inductively heat the sealless nozzle to a second temperature.
A change core module coupling apparatus of an injection mold for a hydrogen tank liner that is injection molded with a sealless nozzle positioned in the injection mold by upper and lower change cores, wherein the injection mold comprises upper and lower molds, the change core module coupling apparatus comprising:
- a horizontal movement pin configured to be built into the lower change core and horizontally moved by an ejector pin on a bottom plate;
- and
- a vertical movement pin configured to be built into the lower change core, vertically moved by the horizontal movement pin, and inserted into a coupling hole of the upper change core.
A method of forming a hydrogen tank liner, the method comprising:
- positioning a sealless nozzle in an injection mold comprising upper and lower molds using a change core module, the change core module comprising upper and lower change cores holding the sealless nozzle inside the injection mold;
- and
- inductively heating the sealless nozzle from a first temperature to a second temperature using an induction heating device of the change core module.
