Injection molding system having movable molding device and method thereof

An injection molding system, including:

• an injection station including a platform, an injector disposed over the platform and a chamber under the platform, wherein the platform includes a first opening extending through the platform and communicable with the chamber;
• a first molding device disposed between the platform and the injector and over the first opening and including a first mold base, a second mold base opposite to the first mold base, a mold cavity surrounded by the first mold base and the second mold base, and a clamping unit disposed between the first mold base and the second mold base and configured for clamping the first molding device, wherein the first molding device and the clamping unit are movable away from the injection station, and the clamping unit and the platform are separable from each other;
• and
• a plunger disposed under the platform and movable into and out of the chamber, wherein the plunger includes a base and a rod, the rod is extendable through the first opening to contact and press the first molding device and retractable toward the base and away from the first molding device,
• wherein the first molding device, the plunger, the first mold base, the second mold base and the clamping unit are movable together relative to the platform.

An injection molding system, including:

• an injection station including a platform, an injector disposed over the platform, and a housing disposed under the platform, wherein the platform includes a first opening extending through the platform;
• a molding device disposed between the platform and the injector and over the first opening, wherein the molding device includes a mold cavity defined by a first mold and a second mold disposed over and corresponding to the first mold, and a clamping unit for clamping the molding device and separable from the platform;
• a first mold base and a second mold case disposed over the first mold base, wherein the molding device is disposed between the first mold base and the second mold base and is surrounded by the clamping unit;
• a locking device configured to lock the molding device on the platform, wherein the locking device includes a first locking element disposed on the first mold base and a second locking element disposed on the platform and engageable with the first locking element;
• and
• a plunger disposed under the platform and molding device and entirely surrounded by the housing and the platform, wherein the plunger includes a base and a rod, the rod is extendable through the first opening toward the molding device and configured to apply a plunging force on the molding device, the rod contacts the first mold during application of the pushing force and presses the first mold toward the second mold, and the rod is retractable toward the base,
• wherein the molding device and the clamping unit are movable together relative to the platform,
• the plunger is disposed out of the molding device, and
• the first mold base is disposed between the clamping unit and the platform when the molding device is disposed on the platform.
