1. A device for producing a skin care pack using hydrogel, the device comprising:
a housing which is provided with a door for selectively opening and closing a work space for forming a skin care pack, and which maintains a forming temperature required for producing the skin care pack;
a platform having a base supported on a floor plate of the work space of the housing;
a former including one or more nozzle modules which are provided to be movable in the work space, and which heat the hydrogel and discharge same onto the platform; and
a control unit for controlling movement of the nozzle modules and discharge of the hydrogel from the nozzle modules,
wherein an individual nozzle module of the nozzle modules includes:
a main block which includes a heater, and which is formed of a thermally conductive material;
a syringe which is installed at the main block, and which stores the hydrogel;
a nozzle which is installed at the main block, and which discharges the hydrogel onto the platform; and
a pump which is installed at the main block, and which supplies the hydrogel from the syringe to the nozzle, and
wherein the platform includes:
a z-axis linear driving device which is driven according to a control signal supplied by the control unit, and which is installed on the floor plate of the housing;
a base which is ascended or descended along a z-axis direction by the z-axis linear driving device, which is disposed above a driving device protection cover of the work space of the housing, and which has a plurality of film seat portions partitioned by a peripheral stepped portion so that a pattern part constituting a mask pack are dividedly formed into a plurality of pieces; and
a plurality of film holders which are attached to or detached from the peripheral stepped portion of the base by a means of magnetic force.
