Abstract:
A device for shaping the visors of caps, comprising:a visor shaping unit comprising:a base frame having both a support floor and a support roof, said base frame also having a controller, a temperature/time setting unit and a start switch;a plurality of sets of molds regularly arranged on the base frame and adapted for heating and shaping the visors into a desired curvature, each of the sets of molds comprising:a hydraulic cylinder having a retractable piston rod, said cylinder being vertically mounted to the support roof of the base frame using an upper bracket, with the piston rod being vertically directed toward the support floor of the base frame;a movable upper mold outwardly curved into the desired curvature at a lower surface thereof, said upper mold being mounted to a lower end of the piston rod of the hydraulic cylinder, thus being movable along with the piston rod under the control of the controller;a coil heater set in the upper mold and adapted for heating the upper mold to a predetermined temperature;a temperature sensor set in a recess formed on a front portion of the upper mold and adapted for sensing a temperature of the upper mold;a lower mold inwardly curved into the same curvature as that of the upper mold at a top surface thereof, said lower mold being mounted to the support floor of the base frame using a lower bracket; anda clamp member attached to the top surface of the lower mold while being curved into the same curvature as that of said top surface of the lower mold; anda cooling unit having first to third chambers at an upper portion thereof, said first to third chambers being positioned in a stepped arrangement and individually having a plurality of perforated sections at a top wall thereof, said cooling unit comprising:a set of curved panels exteriorly attached to the top wall of each of the chambers at a position covering each of the perforated sections, the set of curved panels consisting of a perforated upper panel and a perforated lower panel with a curved gap being defined between the two perforated panels; anda cool air fan connected to the first to third chambers through first to third air pipes and adapted for supplying pressurized cool air into the first to third chambers.
