In a cavity (not shown) formed by the mold 32. Finally, a second mold opening is performed to separate the first male mold 44 from the second female mold 32, and the second male mold 45 and the first female mold 22 are separated from the mold. Two-color finished product is sufficient.

As shown in Figures 1, 3, 6, and 7, it is worth mentioning that in order to store and protect several pipelines 8 (such as water pipes, oil pipes, gas pipes, electric wires, etc.) that are connected to the clamping device 4, the The two-color injection molding machine also includes a pipeline storage device 7 suitable for winding the pipeline 8. The pipeline storage device 7 has a fixedly connected to the turntable 42 and can be rotated with the turntable 42 and passed downward through the base 41. Rotation axis 71, a rotation sleeve 75 fixedly connected to the bottom of the base 41 and enclosing the periphery of the rotation axis 71, a rotation sleeve 75 fixedly connected to the bottom of the rotation axis 71 and the bottom of the rotation sleeve 75 Spaced ring seats 72, a storage rack 73 erected at the bottom of the base 41 and used to carry the pipeline 8, and a bendable position beside the storage rack 73 and allow the pipeline 8 to extend through Aligned protection chain 74.

The ring base 72 has a ring body 722 which is hollow and can be used for the pipeline 8 to be wound on the periphery, a chassis body 721 which is circular and connected to the bottom edge of the ring body 722, and a ring body 722 from the ring.

Then, the protective chain 74 is collectively loaded. When the clamping device 4 rotates relative to the machine table 1, as the turntable 42, the rotation axis 71 and the ring seat 72 rotate, the pipeline 8 will be in a rolled state as shown in FIG. 7 and as shown in FIG. 7. The winding state of 8 is changed. In the rolled state, the pipeline 8 will be tightly bundled around the ring body 722. In the rolled state, the pipeline 8 will be loosened and placed on the carrier. On 732, the pipeline 8 can be prevented from falling out and scattered on the ground, so the pipeline 8 will not cause curling, overflowing or twisting. Furthermore, the protection chain 74 can centrally manage the pipeline 8 to ensure that When the clamping device 4 is translated relative to the machine, the pipeline does not fall apart.
