Abstract
An injection molding system is disclosed, and comprises an extrusion system configured to produce a mixture; a discharge channel communicated with the extrusion system and including an outlet configured to discharge the mixture; and a forming device configured to receive the mixture. Each of the forming devices comprises a hollow space and a feeding port communicated with the hollow space and connected with the outlet. An injection molding method includes providing the extrusion system configured to produce the mixture, a discharge passage including an outlet, and first and second molding devices; engaging the outlet with the first forming device; injecting the mixture into the first forming device; separating the outlet from the first forming device; moving the discharge channel away fromthe first forming device and towards the second forming device; engaging the outlet with the second forming device; injecting the mixture into the second forming device; and separating the outlet from the second forming device.
Description
[0001] Related Application Cross Reference [0002] This application claims Taiwan Patent Application No. 108124178 filed on July 9, 2019, U.S. Provisional Application No. 62 / 915,287 filed on October 15, 2019, and No. Priority to U.S. Provisional Application No. 62 / 950,454, and U.S. Patent Application No. 16 / 748,374, filed January 21, 2020, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to an injection molding system and an injection molding method, in particular to an injection molding system and an injection molding method for manufacturing foamed polymer objects. Background technique [0004] Foamed polymer materials have many advantages such as high strength, low weight, impact resistance, heat insulation, and the like. Foamed polymer objects can be produced by injection molding or extrusion. For example, after the polymeric material is melted and the blowing agent is mixed to form the mixture, ...
