[0018] A highly stable multi-color injection molding structure, as shown in Figures 1-5, includes a protective box 1, a first injection module 2, a second injection module 5, a feed pipe 3, an electric push rod 4, guide rods 6, an inlet pipe 7, and foot pads. The first injection module 2 is fixedly installed on the right end of the protective box 1. Multiple guide rods 6 are connected to the left edge of the first injection module 2. Two feed pipes 3 are installed in the middle right side of the first injection module 2, and the injection port 30 is connected to the feed pipes 3. The second injection module 5 is slidably connected to the guide rods 6. The electric push rod 4 is fixedly installed on the left end of the protective box 1. The telescopic rod of the electric push rod 4 is connected to the second injection module. Block 5 is connected, and the electric push rod 4 is used to drive the second injection molding module 5 to move. The first injection molding module 2 has mold grooves 201 symmetrically arranged on the left side and the second injection molding module 5 has mold grooves 201 symmetrically arranged on the right side. Six cooling grooves 71 are spaced apart inside the first injection molding module 2 and the second injection molding module 5. Each cooling groove 71 is equipped with a liquid inlet pipe 7 to facilitate the cooling of the injection molded parts. The high-stability multi-color injection molding structure also includes cross-beams 8, which are embedded in the inner wall of the mold grooves 201 of the first injection molding module 2 and the second injection molding module 5 to enhance the stability of the stress surface. The dovetail grooves 9 are connected to the cross-beams 8 on the front and rear sides to reduce the area of ​​waste material to be removed during demolding. The feet are fixedly installed at the bottom of the protective box 1 to improve the stability of the equipment and reduce vibration.

[0019] When the equipment is running, the operator first loads different colored plastic raw materials into the two feed pipes 3 to ensure sufficient material. Then, the operator starts the equipment, and the electric push rod 4 starts working, driving the second injection module 5 to slide to the right along the guide rod 6, so that the mold grooves 201 of the first injection module 2 and the second injection module 5 are aligned and closed, forming a complete injection mold space.

[0020] Next, the plastic raw material enters the mold groove 201 through the feed pipe 3 below. After the raw material is injected, coolant is introduced through the liquid inlet pipe 7 to accelerate the solidification of the plastic raw material. After solidification is completed, the input of coolant is stopped. Then, another color of plastic raw material is injected into the mold groove 201 through the feed pipe 3 above. After injection, coolant is also introduced to accelerate the solidification of the plastic raw material. The cross mesh 8 distributes the force in the mold groove 201 through its cross structure, enhances stability, and prevents deformation.

[0021] After injection molding is complete, the electric push rod 4 actuates again, driving the second injection module 5 to slide to the left along the guide rod 6, opening the mold slot 201. The dovetail groove 9, through its structural design, reduces waste residue and facilitates demolding. After the operator removes the molded product, they clean the small amount of waste material from the mold slot 201. The foot pads provide stable support and reduce equipment vibration throughout the process. Finally, the operator shuts down the equipment, the electric push rod 4 stops operating, the second injection module 5 resets, and the equipment returns to its initial state, ready for the next use.
