By starting the water pump inside the circulating water tank 11, the cooling water enters the cooling water cavity inside the first mold 5 and the second mold 6 through the water inlet trough 12 and the water inlet pipeline 52, and then flows back to the inside of the circulating water tank 11 through the water outlet pipeline 53 and the return water trough 13 to complete the cooling.

The guide block below the first mold 5 is slidably connected to the inside of the first slide groove 41, and the guide block below the second mold 6 is slidably connected to the second slide groove 42, and a spring 63 is installed between the guide block below the second mold 6 and the inner wall of the second slide groove 42.

[0038] like Figure 6 As shown, a guide seat 54 is fixedly connected to the top of the rotating platform 4 , and the guide seat 54 is used to guide the T-shaped rod 55 .

[0039] like Figure 6 As shown, a feeding channel 62 is provided on a side of the second mold 6 away from the first mold 5 . The feeding channel 62 is communicated with the interior of the second molding chamber 61 , and the feeding channel 62 corresponds to the output end of the extruder 2 .

The design of the sliding block 742 and the sliding groove 721 facilitates the sliding of the first mold 5 and the second mold 6 to dock with the output end of the extruder 2.

[0043] In order to further better explain the above embodiment, the present invention also provides an implementation scheme, a method for producing a thermally conductive plastic, comprising the following steps:

[0044] S1: First, the raw materials are mixed and put into the silo of the extruder 2. The raw materials are melted by the action of the internal screw and the heating component of the extruder 2;

[0045] S2: Start the motor 31, so that the spur gear 32 and the gear ring 34 mesh with each other, driving the rotating table 4 to start rotating counterclockwise, and the eccentric shaft 36 meshes with the rotating table 4 through the fan-shaped tooth groove 35, pushing the T-shaped rod 55 to ensure that the feed channels 62 of the first mold 5 and the second mold 6 are connected with the output end of the extruder 2;

[0046] S3: The cooling system is started, and the cooling water is pumped into the internal cooling water chambers of the first mold 5 and the second mold 6 through the water inlet groove 12 and the water inlet pipe 52, and then the cooling water flows back to the circulating water tank 11 through the water outlet pipe 53 and the return groove 13;

[0047] S4: the extruder 2 injects the molten plastic raw material into the molding cavity between the first mold 5 and the second mold 6, and the raw material enters the second molding cavity 61 and the first molding cavity 51 through the feed channel 62 of the second mold 6;

[0048] S5: After the extruder 2 stops injection molding, the driving mechanism 3 continues to drive the rotating table 4 to rotate counterclockwise, driving the mold to continue to move so that it can be cooled. During the rotation process, the cooling water inside the mold continues to flow to keep the temperature inside the mold constant, ensuring that the product is fully cooled and shaped;

[0049] S6: When the mold-parting and mold-closing mechanism 7 passes the position of the first tooth plate 8, the meshing gear 73 drives the rotating shaft 72 and the transmission shaft 74 to rotate, so that the first mold 5 and the second mold 6 are separated;

[0050] S7: The unloading robot 10 enters between the molds and takes out the molded product;

[0051] S8: When the mold splitting and clamping mechanism 7 passes the second gear plate 9, the meshing gear 73 drives the transmission shaft 74 and the external thread 75 to rotate again, so that the first mold 5 and the second mold 6 are recombined to prepare for the next round of injection molding. This process is continuously cycled until all production tasks are completed.

[0052] Working principle: First, the spur gear 32 on the top of the motor 31 engages with the gear ring 34 to drive the eccentric shaft 36 to rotate. When the fan-shaped tooth groove 35 on the eccentric shaft 36 engages with the rotating table 4, the rotating table 4 is driven to rotate counterclockwise. When the fan-shaped tooth groove 35 is no longer engaged with the rotating table 4, the first mold 5 and the second mold 6 are opposite to the output end of the extruder 2. As the rotating disk 33 rotates, the eccentric shaft 36 on the top of the rotating disk 33 pushes the T-shaped rod 55, so that the first mold 5 and the second mold 6 move toward the center of the rotating table 4 until the feed channel 62 on the side of the second mold 6 corresponds to the output end of the extruder 2. Then the extruder 2 extrude the molten raw material between the first mold 5 and the second mold 6, and cools the first mold 5 and the second mold 6. The system injects water into the cooling water chamber inside the first mold 5 and the second mold 6 for cooling, and then the driving mechanism 3 continues to drive the rotating table 4 to rotate, and the first mold 5 and the second mold 6 on the rotating table 4 continue to complete injection molding, and the first mold 5 and the second mold 6 continue to rotate and cool after the injection molding is completed. When the mold separation and clamping mechanism 7 passes the position of the first tooth plate 8, under the meshing action of the first tooth plate 8, the mold separation and clamping mechanism 7 separates the first mold 5 and the second mold 6, and the material is unloaded by the unloading robot 10. Then, when the mold separation and clamping mechanism 7 passes the second tooth plate 9, the first mold 5 and the second mold 6 are combined again to prepare for the next injection molding, and the cycle injection molding is completed at this point, with high work efficiency.
