Abstract
An injection molding system and method are disclosed. The injection molding system includes a molding device and injector. The molding device defines a mold cavity and includes an inlet portion in communication with the mold cavity. The injector includes a discharging channel. An end portion of the inlet portion and an end portion of the discharging channel have non-planar end surfaces respectively, which are engageable with each other.
Claims20
An injection molding system, comprising:
- a molding device defining a mold cavity and including an inlet portion in communication with the mold cavity, wherein the inlet portion includes an end portion having an end surface, and the end surface of the inlet portion includes a first surface and a second surface non-coplanar with each other;
- and
- an injector including a discharging channel, wherein the discharging channel includes an end portion having an end surface, and the end surface of the discharging channel includes a first surface and a second surface non-coplanar with each other,
- wherein the first surface of the end surface of the discharging channel entirely contacts the first surface of the end surface of the inlet portion, and the second surface of the end surface of the discharging channel entirely contacts the second surface of the end surface of the inlet portion,
- wherein in a cross-sectional view, a length of the first surface of the end surface of the discharging channel is substantially equal to a length of the first surface of the end surface of the inlet portion, and a width of the second surface of the end surface of the discharging channel is substantially equal to a width of the second surface of the end surface of the inlet portion,
- wherein the discharging channel defines a passage having an opening at the second surface, and a width of the passage is less than the width of the second surface of the end surface of the discharging channel,
- wherein the second surface of the end surface of the inlet portion is substantially parallel with a top surface of the molding device.
