| Abstract: | The characteristics of the heat transfer mechanism in the hot press tank result in uneven heating of different parts of the mold, and the curing gradient ultimately affects the curing quality of the product. In order to improve the temperature uniformity during the solidification process of the mold surface, a simulation model of the flow solid coupling of the hot press tank is established using simulation methods. The temperature field and flow field during the operation of the hot press tank are analyzed, and two methods of adding a horizontal plate or a vertical plate at the front of the mold are proposed. By comparing the data and temperature distribution contour maps before and after optimization, it is demonstrated that both optimized molds achieve the effect of improving the temperature uniformity of the mold surface during the solidification process. The horizontal plate mold can effectively avoid direct contact between the front end of the mold and the hot air flow, reducing the area of the temperature leading region; the vertical plate enhances the heat conduction intensity between the back of the mold and the hot air flow by accelerating the local airflow beneath the mold surface. |
