[0002] The initial product of a thin-film capacitor core is an electronic element formed by overlapping and rolling a polyester film or a polypropylene film with a metal evaporation layer on one or both sides.

The other end of the hydraulic channel 21 is arranged in the hydraulic inner tube 15. The first oil injection channel 22 is arranged in the inside of the hydraulic inner tube 15, and the second oil injection channel 23 is arranged between the hydraulic inner tube 15 and the hydraulic outer tube 16. The cross sections of the hydraulic inner tube 15, the hydraulic outer tube 16, the telescopic inner tube 17, and the telescopic outer tube 18 are all circular and coaxially arranged. The hydraulic base 14 is used to install the hydraulic inner tube 15 and the hydraulic outer tube 16. The hydraulic base 14 is fixedly connected with the sizing guide rod 9.

When the hydraulic oil in the second hydraulic cavity is pumped away through the second oil injection channel 23, the telescopic outer tube 18 moves to the hydraulic base 14 side. The telescopic outer tube 18 and the telescopic inner tube 17 move together. The telescopic inner tube 17 drives the shaping press plate 8 to relax the formed film capacitor core. At the same time, the hydraulic oil in the first hydraulic cavity enters the balance channel 13, the limiting outer sleeve 10 and the limiting inner sleeve 11 through the hydraulic channel 21 and the hydraulic conduit 12, so that the shaped middle plate 7 and the shaped middle plate 7 are separated, and the shaped middle plate 7 and the shaped base 6 are separated, thereby releasing the pressed film capacitor core. The limiting baffle ring 19 is fixed on the hydraulic outer tube 16 to limit the movement distance of the telescopic outer tube 18, so as to prevent the separation between the telescopic outer tube 18 and the hydraulic outer tube 16.

The first heating component 27 is an electric heating component in the prior art. The first heat-conducting plate 26 is arranged to prevent the material disc 47 from falling into the heating hole. Generally, the area of the material disc 47 is smaller than the area of the heating hole, which is better for the thin-film capacitor core. The first heating component 27 heats the material disc 47 and the thin-film capacitor core. Generally, the temperature of the thin-film capacitor core is controlled between 82 and 88℃. The upper surface of the lowermost hierarchical plate 25 is flush with the upper surface of the shaping base 6.

[0036] In some embodiments, the heating assembly further comprises a heat insulation plate 30, a second heat-conducting plate 31 and a second heating component 32.

The second heating component 32 is arranged between the heat insulation plate 30 and the second heat-conducting plate 31. The second heating component 32 is an electric heating component in the prior art. The heat insulation plate 30 prevents the temperature in the warming box 2 from being lost through the warming box 2. The second heating component 32 heats the space of the inner wall of the warming box 2, which makes the thin-film capacitor core be heated more uniformly and prevents the thin-film capacitor core from being damaged due to uneven heating. The second heat-conducting plate 31 prevents the material disc 47 from accidentally hitting the second heating component 32 during the pushing process, which prevents the second heating component 32 from being damaged.

[0037] In some embodiments, a partition assembly is sealingly arranged on the feeding channel 5, which includes a movable door 33, a fixed door 34, a limiting frame 35 and a door driving member 36. The fixed door 34 is sealingly and fixedly arranged on one end of the feeding channel 5 and close to the side of the shaping box 1. The limiting frame 35 is fixedly arranged on the other end of the feeding channel 5 and is arranged in parallel with the fixed door 34. The movable door 33 is slidingly arranged between the fixed door 34 and the limiting frame 35. The fixed door 34 is provided with a first passing opening 45. The movable door 33 is provided with a second passing opening 46 matched with the first passing opening 45. The door driving member 36 is a gas pressure rod or a hydraulic cylinder in the prior art. The cylinder body of the door driving member 36 is fixed on the outside of the feeding channel 5. Since the length of the feeding channel 5 is relatively short, the door driving member 36 is fixed on the shaping box 1 and the heating box 2. The fixed door 34 and the movable door 33 are tightly combined to realize sealing. Figure 3 As shown in FIG. 4, the first passing opening 45 and the second passing opening 46 are only mismatched. At this time, the tray 47 in the heating box 2 cannot enter the shaping box 1. When it is needed to send the tray 47 in the heating box 2 into the shaping box 1, the door driving member 36 is controlled to lift the movable door 33 upward, so that the first passing opening 45 is matched with the second passing opening 46, as shown in FIG. 5. At this time, the tray 47 in the heating box 2 can be pushed into the shaping box 1. Figure 4 The number of the cushioning tables 41 is equal to the number of the first passing openings 45 and is matched. The upper surface of the cushioning table 41 is not higher than the lower surface of the first passing opening 45. When the first passing opening 45 is matched with the second passing opening 46, the lower surface of the first passing opening 45 is flush with the lower surface of the second passing opening 46. The lower surface of the first passing opening 45 is not higher than the upper surface of the hierarchical plate 25. In this way, the tray 47 can be smoothly sent from the heating box 2 into the shaping box 1, and the movement of the tray 47 is prevented from being blocked by the first passing opening 45 or the second passing opening 46 or the cushioning table 41. The height of the first passing opening 45 and the second passing opening 46 is greater than the total height of the tray 47 plus the diameter of the film capacitor core. In this way, the first passing opening 45 and the second passing opening 46 are prevented from being stuck with the film capacitor core and cannot be moved.
