FIELD OF THE INVENTION
The present invention generally relates to the field of injection molding. In particular, the present invention is directed to methods and systems for producing a product utilizing a mold liner.
BACKGROUND
Many types of objects are manufactured utilizing injection molding. The injection molding manufacturing process works by injecting molten material into a hollow cavity of a two-part mold. The molten material can include a variety of materials, typically being thermoplastic polymers, thermosetting polymers, metals, glasses, and elastomers. The molten material cools within the hollow cavity, creating a completed part. The two parts of the mold are separated and the completed part remains adhered to one half of the mold. Ejector pins are used to remove the completed part from one half of the mold by pushing up from the surface of the mold and engaging the bottom of the completed part. However, utilizing ejector pins to release the completed part during the injection molding manufacturing process generates a high level of complexity to mold set. Additionally, ejector pins create imperfections in the completed part because each ejector pin utilized will leave a mark where the pin contacted the completed part.

In an embodiment, and without limitation, the alignment pins are configured to guide the motion of the assembly of collar lock 112 and liner 108 lifting away from first half of the mold 104. As the assembly of collar lock 112 and liner 108, including formed product 204, reach the limit of lift, an additional pressure is introduced causing liner 108 to bow outward, as described above in further detail in reference to FIGS. 1A-1B. Injecting a gas into completed first half of the mold 200 is configured to further include injecting the gas through first half of the mold 104 and through liner 108 by use of a release hole of liner 108. The release hole of liner 108 may include any release hole as described in the entirety of this disclosure. The release hole is configured to allow air to flow through liner 108 to the formed product, as described above in further detail in reference to FIGS. 1A-2B. The release hole is designed and configured to facilitate the release of formed product 204 by allowing air to flow in between liner 108 and formed product 204, as described above in further detail in reference to FIGS. 1A-2B. The release hole may include any diameter suitable as a diameter to allow air to flow though liner 108 to formed product 204 but prevents molten material from flowing through liner 108 to formed product 204, as described above in further detail in reference to FIGS. 1A-2B. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various methods of ejecting which may be suitable for use as methods of ejecting liner 108 and formed product 204 from completed part 200 consistently with this disclosure.
Continuing to refer to FIG. 9, at step 925, system 100 releases formed product 204 from liner 108. Release of formed product 204 may include any suitable method of releasing formed product 204 from liner 108, as described above in further detail in reference to FIGS. 1A-3B. Release of formed product 204 may include a manual process of release, an automated process of release, and/or any combination thereof. In an embodiment, release of formed product 204 from liner 108 may include flexing liner 108 outward to facilitate release of formed product 204, as described above in further detail in reference to FIGS. 1A-3B. Release of formed product 204 is further configured to include, for example and without limitation, repositioning of the assembly of collar lock 112 and liner 108 on the first half of the mold 104, wherein the assembly moves down the at least an alignment pin and is guided back into alignment with first half of the mold 104, as described above in further detail in reference to FIGS. 1A-3B. Persons skilled in the art, upon reviewing the entirety of this disclosure, will be aware of various methods of release which may be suitable for use as the formed product consistently with this disclosure.
The foregoing has been a detailed description of illustrative embodiments of the invention. Various modifications and additions can be made without departing from the spirit and scope of this invention. Features of each of the various embodiments described above may be combined with features of other described embodiments as appropriate in order to provide a multiplicity of feature combinations in associated new embodiments. Furthermore, while the foregoing describes a number of separate embodiments, what has been described herein is merely illustrative of the application of the principles of the present invention. Additionally, although particular methods herein may be illustrated and/or described as being performed in a specific order, the ordering is highly variable within ordinary skill to achieve embodiments according to this disclosure.
