Abstract
A mold for an injection molding tool. The mold has a pin gate extending between a gate inlet and a gate opening. The pin gate forms a tapered, cylindrical channel through a body of the mold and abruptly transitions to a smooth funnel. The gate opening is positioned at an end of the funnel. The pin gate is configured to receive molding material from a runner channel of the injection molding tool at the gate inlet and dispense the molding material at the gate opening. The mold also has a mold cavity in fluid connection with the gate opening of the pin gate and configured to receive the molding material therefrom.
Claims22
A mold adapted for an injection-molding tool, the mold having:
- a main body made from a material comprising a plastic material and filler material, the main body having one side forming a mold cavity;
- and
- a gate having a first end with an opening arranged for being connected to a sprue or a runner channel arranged in the injection molding tool, and a second end forming a most constricted gate opening into the mold cavity,
- wherein the main body forms at least the second end of the gate.
