The invention relates to intermittent micro-foaming injection molding equipment and an intermittent micro-foaming
injection molding process. the intermittent micro-foaming injection molding equipment mainly comprises a
supercritical fluid permeable
system provided with a permeable kettle, a storing
system, and an injection molding
system provided with a loading hopper, wherein the storing system mainly comprises a fetching device, a condensing storing
barrel and a metering feed device; the fetching device is used for taking out saturated
raw material in the permeable kettle and then sending the saturated
raw material into the condensing storing
barrel, the condensing storing
barrel is used for sending the saturated
raw material into the loading hopper of the injection molding system through the metering feed device. The specific process mainly comprises the following steps: arranging the raw material in the permeable kettle, releasing pressure after performing the saturated
permeation by using the
supercritical fluid so as to obtain the saturated raw material, adding the saturated raw material in an
injection molding machine, fusing and plasticizing to obtain a homogeneous solution of
polymer / gas to finish the injection; cooling and
sizing, opening die to obtain a product. According to the intermittent micro-foaming injection molding equipment and the intermittent micro-foaming
injection molding process disclosed by the invention, certain production efficiency is achieved, the micro-foaming injection molding can be controlled easily, and the complexity degree of the equipment transformation can be lowered.
