Hot-runner valve gate for injection molds

摘要

The present invention relates to a hot-runner valve gate for an injection mold, in which a resin flow channel (18) is inclined so as to minimize swinging of the valve pin (2) The guide bush 10 is extended to the center of the blanket 18 so as to accurately hold the center of the valve pin 2 so that the valve pin 2 is easily aligned with the center hole of the valve gate 17, A resin escape groove 21 is formed in the inner circumferential surface of the hollow portion 24 at the tip end of the runner valve so that the residual resin flows backward in the discharge of the resin, and the temperature sensor 16 in the hot-The resin layer forming space 20 is formed between the mold gate 17 and the hot runner valve 12 so that the temperature of the resin layer 18 can be accurately detected (2) length adjustment between valve pin (2) and piston. And the valve pin 22 is fixed by the tongue bolt 3 so as to penetrate the cylinder gap 4 to connect the piston 6 It is a hot-runner valve gate for an injection mold that is easily disassembled.
