POLYURETHANE CELL FOAMING MIXING HEAD WHICH HAS ULTRASONIC HORN

摘要

The present invention relates to a mix head for foaming a microcellular polyurethane having an ultrasonic oscillator for foaming a bubble size in a polyurethane in foaming a polyurethane. The present invention relates to a mix head for foaming microcellular foams, which comprises a polyol mixture and an isocyanate A mixer head for foaming polyurethane microcells for finely forming bubble nuclei upon foaming by means of ultrasonic waves by attaching an ultrasonic oscillator for generating ultrasonic waves on the discharge hole when the mixture is mixed into the mold along the discharge port The present invention relates to a piston having a bypass groove (18a, 18b) on a circumferential surface thereof, a piston (17) slidably coupled to the cylinder (11) and reciprocating as hydraulic pressure is supplied and discharged, A mixture of the polyol mixture and the isocyanate mixture which are respectively connected to the grooves 18a and 18b A mixing head 10 having inlet ports 15a and 15b and an outlet 19 communicating with the mixture circulation holes 16a and 16b to be returned; A slider (30) slidably coupled to the cylinder (31) and passing through the discharge port (19) in a perpendicular direction; Moving means for reciprocating the slider (30); And a horn 40 having a cross section fixed on the discharge port 19 and connected to the ultrasonic wave generator so as to be separated from the end of the slider 30 by a predetermined distance.
