Abstract
Official abstract text for this publication.
A nozzle touch mechanism ( 50 ) includes a base frame ( 6 ), a stationary platen ( 4 ) to which a mold ( 5 ) is to be attached, and an injection mechanism ( 1 ). The injection mechanism ( 1 ) is moved it toward the stationary platen ( 4 ) by means of a ball screw shaft ( 11 ). A motor portion ( 14 ) which applies a pressing force to the mold ( 5 ) from a nozzle ( 3 ) is connected to one end ( 11 a ) of the ball screw shaft ( 11 ). A connection mechanism ( 7 ) is provided which is connected to the other end ( 11 b ) of the ball screw shaft ( 11 ) and to the stationary platen ( 4 ) at a support located above the center of the nozzle ( 3 ). When no pressing force is applied to the mold ( 5 ) from the nozzle ( 3 ) by the motor portion ( 14 ), springs ( 18 ) can press the connection mechanism ( 7 ) in such a direction as to move it away from the stationary platen ( 4 ) with respect to the base frame ( 6 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A nozzle touch mechanism comprising: a base frame comprising a first guide mechanism and a second guide mechanism; a stationary platen fixed to the base frame, to which a mold is to be attached; an injection mechanism configured to move toward and away from the stationary platen; a nozzle attached to the injection mechanism; a movement mechanism configured to move the injection mechanism toward and away from the stationary platen; a drive mec…
