Detailed Embodiment:

[0022] The following further describes the present utility model in conjunction with the drawings, as Figures 1-4As shown in the figure, the utility model includes a forming lower die 1, a forming upper die 2 slidably connected vertically above the forming lower die 1, a forming power mechanism for driving the sliding of the forming upper die 2, and a heat drying device 3 for heat drying the material film. The forming power mechanism is a well-known prior art and is not shown in the figure. The forming lower die 1 includes a lower die base 11, and a forming die cavity 12 is formed at the top of the lower die base 11. The forming upper die 2 includes an upper die base 21, a forming die core 22 provided at the bottom of the upper die base 21, and a flanging ring 23 floatingly arranged vertically below the outer side of the forming die core 22. The output end of the forming power mechanism is drivingly connected to the upper die base 21. The forming die core 22 includes a stamping part 221 and a punching part 222 protruding outward around the top of the stamping part 221. When processing and forming the rice cooker panel film by the utility model, first place the material film at the position of the forming die cavity 12 of the lower die base 11, heat dry and soften the material film through the heat drying device 3, and then drive the upper die base 21 to move downward through the forming power mechanism. As the upper die base 21 gradually moves downward, the flanging ring 23 first presses down the four sides of the material film, and then the stamping part 221 presses the material film pressed by the flanging ring 23 downward to the bottom of the forming die cavity 12, and then punches the material film through the punching part 222. Drive the upper die base 21 to move upward and reset through the forming power mechanism, and take out the processed and formed rice cooker panel film from the forming die cavity 12 of the lower die base 11 to complete the whole process of processing and forming the rice cooker panel film. The utility model only needs a set of molds to complete the processing and forming of the rice cooker panel film, which can reduce the overall cost. Only one operation of putting in and taking out is required to complete the processing and forming of the rice cooker panel film, which can greatly improve the processing and forming efficiency of the rice cooker panel film.

[0023] The forming upper die 2 further includes a plurality of T-shaped rods 24. The T-shaped rods 24 include large cylindrical ends 241 and small cylindrical ends 242 provided at the bottoms of the large cylindrical ends 241. The upper die base 21 is formed with stepped holes 211 having the same number as the T-shaped rods 24. The small cylindrical ends 242 of the respective T-shaped rods 24 are respectively inserted downward through the corresponding stepped holes 211 and connected to the flanging ring 23. Compression springs 25 are respectively sleeved on the small cylindrical ends 242 of the respective T-shaped rods 24. One ends of the respective compression springs 25 respectively abut downward against the tops of the flanging ring 23, and the other ends of the respective compression springs 25 respectively abut upward against the bottoms of the upper die base 21. When the upper die base 21 moves downward to the position where the flanging ring 23 contacts the top of the lower die base 11, as the upper die base 21 continues to drive the forming die core 22 to move downward, the lower die base 11 pushes the flanging ring 23 upward, the respective T-shaped rods 24 slide upward respectively, the respective compression springs 25 are in a compressed state, and the flanging ring 23 and the top of the lower die base 11 press the four peripheral edges of the material film.

[0024] The bottom edge of the stamping part 221 is a rounded corner structure. By setting the bottom of the stamping part 221 as a rounded corner structure, it can better prevent the material film from being torn when being downwardly stamped and formed by the stamping part 221, thus better ensuring the quality of the stamping and forming of the material film.

[0025] The cross-sectional shape of the stamping part 221 and the cross-sectional shape of the punching part 222 are similar figures. The punching part 222 protrudes outward from the top of the stamping part 221 at equal intervals. The thickness of the punching part 222 protruding from the stamping part 221 is preferably 0.15 - 0.35 mm. When the stamping part 221 moves downward to the position of the forming cavity 12, since there is a large gap between the edge of the stamping part 221 and the edge of the forming cavity 12, the material film will be downwardly stretched and formed as the stamping part 221 moves downward. When the punching part 222 moves downward to the position of the forming cavity 12, since the edge of the punching part 222 is tangent to the edge of the forming cavity 12, the material film will be cut as the punching part 222 moves downward.

[0026] A through hole 231 for the forming die core 22 to pass through is formed inside the blank holder 23. When the upper die base 21 moves downward to the position where the blank holder 23 contacts the top of the lower die base 11, as the upper die base 21 continues to drive the forming die core 22 downward, the forming die core 22 passes downward through the through hole 231 of the blank holder 23 and inserts into the forming cavity 12.

[0027] The cross-sectional shape of the through hole 231 and the cross-sectional shape of the punching part 222 are similar figures, which can enable the blank holder 23 to better press the four peripheral edges of the material film.

[0028] The heat drying device 3 includes a heat drying component 31 slidably connected above the forming cavity 12 in the horizontal direction and a heat drying power mechanism 32 for driving the heat drying component 31 to slide. The heat drying component 31 includes a heat drying oven 311 and a plurality of infrared heating tubes 312 arranged in the heat drying oven 311. The heat drying power mechanism 32 is drivingly connected to the heat drying oven 311. The heat drying power mechanism 32 drives the heat drying oven 311 to move above the forming cavity 12. After the material film to be processed and formed is heat dried and softened by each infrared heating tube 312 in the heat drying oven 311 for a certain time, then the heat drying power mechanism 32 drives the heat drying oven 311 to retract and reset from above the forming cavity 12 so that the forming upper die 2 can press down and form the material film.

[0029] The forming upper die 2 further includes a plurality of positioning guide posts 26 arranged on the upper die base 21, and the forming lower die 1 further includes positioning guide sleeves 13 arranged on the lower die base 11 with the same number and corresponding positions as the positioning guide posts 26. The cooperation between the positioning guide posts 26 on the forming upper die 2 and the positioning guide sleeves 13 on the forming lower die 1 can improve the overall stability and precision of the die, thus better realizing the processing and forming of the rice cooker panel film.

[0030] Working principle:

[0031] First, place the material film at the position of the forming cavity 12 of the lower die base 11, heat and soften the material film through the heat drying device 3, and then drive the upper die base 21 to move downward through the forming power mechanism. As the upper die base 21 gradually moves downward, the blank holder 23 first presses down on the periphery of the material film, and then the stamping part 221 presses the material film pressed by the blank holder 23 downward to the bottom of the forming cavity 12. Then, the material film is punched by the punching part 222. Drive the upper die base 21 to move upward and reset through the forming power mechanism, and take out the processed and formed rice cooker panel film from the forming cavity 12 of the lower die base 11 to complete the entire process of processing and forming the rice cooker panel film; The utility model only needs a set of molds to complete the processing and forming of the rice cooker panel film, which can reduce the overall cost. Only one operation of putting in and taking out is required to complete the processing and forming of the rice cooker panel film, which can greatly improve the processing and forming efficiency of the rice cooker panel film.

[0032] Certainly, the above description is only the preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
