View Patent ↗A mold-tool system ( 100 ), comprising: a nozzle position-adjustment assembly ( 104 ) being configured to selectively adjust position of a nozzle assembly ( 102 ) between: (i) a nozzle-loaded position, and (ii) a nozzle-unloaded position.
1. A mold-tool system ( 100 ), comprising:
a backing plate;
a manifold plate facing the backing plate;
a nozzle assembly, the manifold plate supporting a positioning of the nozzle assembly; and
a nozzle position-adjustment assembly ( 104 ), the nozzle position-adjustment assembly comprising:
a plate-biasing mechanism constructed and arranged to bias a position of the manifold plate and the backing plate together; and
a plate-moving mechanism constructed and arranged to selectively adjust a position of the manifold plate and the backing plate relative to each other between:
(i) a nozzle-loaded position, and
(ii) a nozzle-unloaded position.
2. The mold-tool system ( 100 ) of claim 1 , wherein:
in the nozzle-loaded position, the nozzle assembly ( 102 ) is positioned in a fixed position, and
in the nozzle-unloaded position, the nozzle assembly ( 102 ) is removable from the fixed position.
3. The mold-tool system ( 100 ) of claim 2 , wherein:
in the nozzle-loaded position, the nozzle assembly ( 102 ) is non-rotatable, and
in the nozzle-unloaded position, the nozzle assembly ( 102 ) is rotatable.
4. The mold-tool system ( 100 ) of claim 2 , wherein:
the nozzle assembly ( 102 ) is spring biased toward the nozzle-loaded position; and
the nozzle position-adjustment assembly ( 104 ) is configured to selectively adjust spring biasing of the nozzle assembly ( 102 ), so that the nozzle assembly ( 102 ) is selectively adjustably positionable between:
(i) the nozzle-loaded position, and
(ii) the nozzle-unloaded position.
5. The mold-tool system ( 100 ) of claim 1 , wherein:
for the case where the plate-moving mechanism ( 114 ) is actuated, the plate-moving mechanism ( 114 ) is configured to overcome, in use, the plate-biasing mechanism ( 116 ) so that the manifold plate ( 110 ) and the backing plate ( 112 ) are moved away from each other, and the nozzle assembly ( 102 ) is selectively moved from the nozzle-loaded position to the nozzle-unloaded position; and
for the case where the plate-moving mechanism ( 114 ) is not actuated, the plate-biasing mechanism ( 116 ) biases, in use, the backing plate ( 112 ) against the manifold plate ( 110 ).
6. The mold-tool system ( 100 ) of claim 1 , wherein:
the plate-moving mechanism ( 114 ) includes:
a cam-jack assembly ( 120 ); and a manifold-mounting assembly ( 122 ) configured to:
(i) operatively rotatably mount the cam-jack assembly ( 120 ) relative to the manifold plate ( 110 ) and the backing plate ( 112 ), and
(ii) permit rotation of the cam-jack assembly ( 120 ), the cam-jack assembly ( 120 ) selectively moving the manifold plate ( 110 ) and the backing plate ( 112 ) relative to each other.
7. The mold-tool system ( 100 ) of claim 1 , wherein:
the plate-biasing mechanism ( 116 ) includes:
a manifold-spring assembly ( 130 ); and
a plate-mounting assembly ( 132 ) configured to operatively mount the manifold-spring assembly ( 130 ) so as to bias the manifold plate ( 110 ) toward the backing plate ( 112 ).
8. The mold-tool system ( 100 ) of claim 1 , wherein:
the plate-moving mechanism ( 114 ) includes:
a cam-jack assembly ( 120 ); and
a manifold-mounting assembly ( 122 ) configured to:
(i) operatively rotatably mount the cam-jack assembly ( 120 ) relative to the manifold plate ( 110 ) and the backing plate ( 112 ), and
(ii) permit rotation of the cam-jack assembly ( 120 ), the cam-jack assembly ( 120 ) selectively moving the manifold plate ( 110 ) and the backing plate ( 112 ) relative to each other; and
the plate-biasing mechanism ( 116 ) includes:
a manifold-spring assembly ( 130 ); and
a plate-mounting assembly ( 132 ) configured to operatively mount the manifold-spring assembly ( 130 ) so as to bias the manifold plate ( 110 ) toward the backing plate ( 112 ).
9. A molding system ( 900 ) having the mold-tool system ( 100 ) of claim l.
10. A runner assembly ( 916 ) having the mold-tool system ( 100 ) of claim l.
11. A nozzle assembly ( 102 ), comprising:
a nozzle position-adjustment assembly ( 104 ), the nozzle position-adjustment comprising:
a plate-biasing mechanism constructed and arranged to bias, in use, a position of a manifold plate and a backing plate together, the manifold plate adapted to support a positioning of the nozzle assembly, the backing plate adapted to face the manifold plate; and
a plate-moving mechanism constructed and arranged to selectively adjust a position of the manifold plate and the backing plate relative to each other between:
(i) a nozzle-loaded position, and
(ii) a nozzle-unloaded position.
