Abstract
A nozzle for directing molding material from a material source to a sprue, includes a first surface adapted to connect the nozzle to the material source. The first surface is also adapted to be adjacent to and pivotally movable relative to the material source and in material communication with the material source. A second surface is adapted to be positioned adjacent to and pivotally movable relative to the sprue. The second surface is in material flow communication with the first surface and adapted to be in material flow communication with the sprue. A channel is included for establishing the material flow communication through the nozzle.
Claims26
A nozzle for directing molding material from a material source to at least one sprue, comprising:
- a first surface adapted to be positioned adjacent to and pivotally movable relative to the material source and in material communication with the material source;
- a second surface adapted to be positioned in contact with and pivotally movable relative to the sprue, wherein the second surface is in material flow communication with the first surface and is adapted to be in material flow communication with the sprue and wherein the second surface is adapted to create a first seal via contact with the sprue prior to the introduction of the molding material and pressure increases associated with said introduction of the molding material;
- and
- channel means for establishing the material flow communication through the nozzle.
