An injection molding device (100) includes an upper mold (30), a core insert (50), and a lower mold (70). The upper mold defines a main flow passage (311) and a cylindrical receiving cavity (331) communicating with the main flow passage. The core insert is rotatably received in the cylindrical rec
An injection molding device (100) includes an upper mold (30), a core insert (50), and a lower mold (70). The upper mold defines a main flow passage (311) and a cylindrical receiving cavity (331) communicating with the main flow passage. The core insert is rotatably received in the cylindrical receiving cavity and defines a secondary flow passage (57) communicating with the main flow passage and at least one upper half molding cavity (531). The lower mold defines at least one lower half molding cavity (711) cooperating with the upper half molding cavity to form a full molding cavity.

I claim: 1. An injection molding device, comprising: an upper mold defining a main flow passage and a receiving cavity communicating with the main flow passage, and further defining two adjusting holes adjacent to the main flow passage; a core insert received in the receiving cavity and comprising two adjusting poles passing through the two adjusting holes so that the core insert is rotatable relative to the receiving cavity and is movable along an axis of the core insert, the core insert defining a secondary flow passage communicating with the main flow passage, and four upper half molding cavities; and a lower mold defining four lower half molding cavities corresponding to the upper half molding cavities and cooperating with the upper half molding cavities to form a full molding cavity. 2. The injection molding device as claimed in claim 1, wherein two adjusting holes each have an arc-shaped cross-section. 3. The injection molding device as claimed in claim 2, wherein the core insert comprises an upper end surface, a lower end surface and a round side surface, the two adjusting poles connecting perpendicularly to the upper end surface. 4. The injection molding device as claimed in claim 3, wherein the secondary flow passage has an upright passage portion running through the middle of the upper end surface, four horizontal passage portions parallel to the lower end surface, each horizontal passage portion communicates with one end of the upright passage portions, four feed passage portions run through the lower end surface and each feed passage portions communicates with one of the horizontal passage portions. 5. The injection molding device as claimed in claim 4, wherein the four upper half molding cavities are located adjacent to the lower end surface, the four upper half molding cavities run through the lower end surface and do not communicate with the secondary flow passages. 6. The injection molding device as claimed in claim 5, wherein the lower mold is substantially a cuboid, including a first wall, an opposite second surface, and a plurality of third side surfaces. 7. The injection molding device as claimed in claim 6, wherein the four lower half molding cavities are located at adjacent to the first surface and the lower half molding cavities runs through the first wall. 8. An injection molding device comprising: an upper mold defining a main flow passage and two adjusting holes adjacent to the main flow passage; a lower mold coupled to the upper mold in such a manner as to allow their separation, a receiving cavity being cooperatively formed between the upper and lower mold, the lower mold defining a lower half molding cavity in communication with the receiving cavity; and a core insert received in the receiving cavity, the core insert defining an upper half molding cavity in communication with the receiving cavity and a secondary flow passage communicating the main flow passage with the receiving cavity, the core insert comprising two adjusting poles connected perpendicularly to the upper end surface for passing through the two adjusting holes so that the core insert is rotatable in the receiving cavity and is movable along an axis of the core insert, wherein after the core insert being assembled between the lower mold and the upper mold, the core insert is configured to be movable relative to the receiving cavity so as to allow the lower half molding cavity and the upper half molding cavity to cooperatively form a full molding cavity. 9. An injection molding device comprising: an upper mold defining a main flow passage; a lower mold coupled to the upper mold in such a manner as to allow their separation, a receiving cavity being cooperatively formed between the upper and lower mold, the lower mold defining a lower half molding cavity in communication with the receiving cavity; and a core insert received in the receiving cavity, the core insert defining an upper half molding cavity in communication with the receiving cavity and a secondary flow passage communicating the main flow passage with the receiving cavity, wherein after the core insert being assembled between the lower mold and the upper mold, the core insert is configured to be manually adjusted to move in the receiving cavity so as to allow the lower half molding cavity to move towards the upper half molding cavity from an offsetting state to an aligning state, wherein the offsetting state is where the secondary flow passage aims at the lower half molding cavity and the lower half molding cavity offsets relative to the upper half molding cavity, and the aligning state is where the secondary flow passage aims at an upper surface of the lower mold adjacent to the lower half molding cavity, and the lower half molding cavity aims at the upper half molding cavity. 10. The injection molding device as claimed in claim 9, wherein the upper mold further defines two adjusting holes adjacent to the main flow passage and the two adjusting holes each have an arc-shaped cross-section, the core insert has two adjusting poles connected perpendicularly to the upper end surface for passing through the two adjusting holes so that the core insert is rotatable in the receiving cavity and is movable along an axis of the core insert. 11. The injection molding device as claimed in claim 10, wherein the upper mold includes an upper wall and a plurality of side walls connecting to the upper wall so as to define the receiving cavity, and the main flow passage runs through the upper wall. 12. The injection molding device as claimed in claim 11, wherein the core insert has a lower end surface, the upper half molding cavity runs through the lower end surface and does not communicate with the secondary flow passages.
