[0026] Embodiment 1:

[0027] Reference Figure 1-4 , a polymer water-absorbing rubber strip molding mold comprises a mold body 1, a mold cavity is provided on the surface of the mold body 1, a feed pipe 3 is connected to the left side of the mold body 1, a heat-conducting ring 4 is sleeved on the surface of the mold body 1, a plurality of brackets 5 are fixedly connected to the outer surface of the mold body 1, and the side of the bracket 5 away from the mold body 1 is fixedly connected to the inner surface of the heat-conducting ring 4, and a cavity 6 is formed between the bracket 5 and the heat-conducting ring 4, and a heat dissipation structure 7 is provided on the left side of the mold body 1, and the heat dissipation structure 7 can guide the external airflow into the cavity 6. By setting the heat-conducting ring 4 to be made of a heat-conducting metal material, the heat on the mold body 1 can be quickly transferred to the cold air in the cavity 6, and the heat-conducting ring 4 can protect the mold body 1 and reduce the damage to the mold body 1 caused by external collision and extrusion. The heat dissipation structure 7 comprises a sleeve 8 arranged between the feed pipe 3 and the mold body 1, and the surface of the sleeve 8 is fixedly connected to an impeller 9. The sleeve 8 is movably connected to the feed pipe 3 and the mold body 1 through a movable oil seal. An injection molding machine screw 10 is arranged on the left side of the material pipe 3, and a connecting rod 11 is fixedly connected to the inner surface of the sleeve 8. The side of the connecting rod 11 away from the sleeve 8 penetrates the feed pipe 3 and extends to the outside of the injection molding machine screw 10, and the inner side of the connecting rod 11 is fixedly connected to a sleeve 12, which is sleeved on the surface of the injection molding machine screw 10 and fixedly connected to the injection molding machine screw 10. A reinforcing rib 13 is fixedly connected to the surface of the feed pipe 3. The number of the reinforcing ribs 13 is several and they are evenly arranged around. The side of the reinforcing rib 13 away from the feed pipe 3 extends to the outside of the heat-conducting ring 4 and is fixedly connected to the heat-conducting ring 4. A fin plate 14 is fixedly connected to the surface of the heat-conducting ring 4. The materials of the fin plate 14, the heat-conducting ring 4 and the bracket 5 are all heat-conducting metal materials. A shielding ring 15 surrounding the surface of the impeller 9 is arranged on the left side of the heat-conducting ring 4. The reinforcing rib 13 is located between the shielding ring 15 and the impeller 9, and the inner surface of the shielding ring 15 is fixedly connected to the surface of the reinforcing rib 13.

[0028] Specifically, when the polymer water-absorbing rubber strip molding mold is working / in use: the injection molding machine screw 10 starts to work, and the molten polymer material is fed into the mold body 1 through the feed pipe 3. The feed pipe 3 and the mold body 1 are connected by a sleeve 8. The sleeve 8 is equipped with an impeller 9. The impeller 9 rotates with the rotation of the injection molding machine screw 10. When the impeller 9 rotates, the airflow effect it generates will guide the external cold air into the cavity 6 between the sleeve 8 and the mold body 1. This cavity 6 is formed by the bracket 5 and the heat-conducting ring 4. The bracket 5 is fixedly connected to the outer surface of the mold body 1, and the heat-conducting ring 4 is sleeved on the mold body 1. The gap between the two is the cavity 6. The cold air entering the cavity 6 flows along the cavity 6 between the bracket 5 and the heat-conducting ring 4 under the impeller 9. Heat exchange is performed with the heat-conducting ring 4 and the mold body 1. Since the heat-conducting ring 4 is made of a heat-conducting metal material, it can quickly transfer the heat on the surface of the mold body 1 to the cold air in the cavity 6, so that the cold air heats up and takes away the heat. At the same time, the fins 14 fixedly connected to the surface of the heat-conducting ring 4 further increase the heat dissipation area and improve the heat dissipation efficiency. As the injection molding process proceeds, the temperature in the mold body 1 will gradually increase, but due to the presence of the heat dissipation structure 7, the mold body 1 can quickly dissipate the heat, thereby maintaining it within a suitable temperature range. This helps prevent material degradation or mold damage caused by excessive temperature, and can also improve the molding quality of the product.
