[0023] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figure 1 As shown, a Y-shaped three-way injection mold for medical devices includes a lower mold base 1 and an upper mold cover 2.

[0026] like Figure 2 As shown, at least one molding cavity 3 is provided in the lower mold base 1, and the molding cavity 3 is adapted to the tee piece; a flow channel 4 is also provided in the lower mold base 1, and the flow channel 4 is connected to the molding cavity 3. In this embodiment, the number of the molding cavities 3 is two.

[0027] A first sliding block 5 is slidably provided on the lower die base 1 at the inlet end of the molding cavity 3 , and the first sliding block 5 is connected to an external driving device.

[0028] like Figure 2 and Figure 3As shown, a guide block 6 is fixed on one side of the discharge end of the molding cavity 3 on the lower die base 1, and two guide through holes 7 are provided in the guide block 6, and the two guide through holes 7 correspond to the two channels of the Y-shaped tee, respectively, and share the same axis with the corresponding channels; a second slider 8 is slidably provided on the outer side of the guide block 6 on the lower die base 1, and two molding rods 9 are hinged on the side of the second slider 8 facing the guide block 6, and the two molding rods 9 are slidably inserted in the corresponding guide through holes 7; an oil cylinder 10 is provided on the lower die base 1, and the oil cylinder 10 is used to drive the second slider 8 to slide. In this embodiment, the guide block 6 is detachably fixed to the lower die base 1 by bolts, which is convenient for disassembly and maintenance.

[0029] like Figure 1 As shown, the upper mold cover 2 covers the lower mold base 1 , and the upper mold cover 2 has an injection port 11 , and the injection port 11 is connected to the flow channel 4 on the lower mold base 1 .

[0030] During injection molding, the first slider 5 is pushed by an external driving device to press against the two feeding ends of the molding cavity 3, and the oil cylinder 10 pushes the second slider 8 so that the two molding rods 9 pass through the two channels of the molding cavity 3; and then the injection molding is performed through the injection port 11 of the upper mold cover 2. After the Y-shaped three-way injection molding part is molded, the oil cylinder 10 drives the two molding rods 9 to move backward and separate from the product. The first slider 5 is also separated from the product under the drive of the external driving device. After the product cools down, it can be taken out.
