Injection molding system and injection molding method

An injection molding method, comprising:

• providing an injection molding system, wherein the injection molding system includes an injection unit and a molding device, the injection unit includes an outlet configured to discharge a flowable mixture, and the molding device is configured to receive the flowable mixture from the outlet and includes a mold cavity and a feeding port communicable with the mold cavity and correspondingly engageable with the outlet;
• providing a supporting device configured to facilitate an engagement of the injection unit and the molding device, wherein the supporting device includes a first element connected to the injection unit and a second element disposed between the molding device and the injection unit;
• extending the first element towards the second element to align a protruding portion of the first element with a slot of the second element;
• displacing the injection unit or the molding device to slide the protruding portion of the first element along the slot of the second element;
• extending the outlet towards the molding device in an opening of the second element to engage the outlet with the feeding port;
• retracting the first element away from the molding device to engage the protruding portion of the first element with the slot of the second element;
• and
• injecting the flowable mixture into the mold cavity,
• wherein the outlet and the first element are individually extendable toward and retractable away from the molding device.
