Description
TECHNICAL FIELD

[0002] With the continuous expansion of the new energy vehicle market in China, the demand for power batteries is increasing, and the power battery is the core energy source of the new energy vehicle, which provides driving power for the new energy vehicle. In the production and manufacturing process of the existing new energy vehicle power battery, a PC insulating plate is usually used. The PC insulating plate is an insulating material formed by die cutting of an insulating and flame-retardant PC film as a base material. The PC insulating plate becomes an important component of a new energy battery pack (cell, module, PACK) due to its excellent insulation, aging resistance, flame retardance and other comprehensive performances. The PC insulating plate can be used in the manufacturing of battery modules and cells as an insulating layer and a flame-retardant layer to improve the safety performance of the battery.
[0003] The PC insulating plate usually uses a forming die in the production process. The forming die usually comprises a shell, a die seat and a heating structure arranged in the shell. The existing heating structure usually uses an electric heater to heat a heating medium, and then uses the heated heating medium to heat the die seat, so as to realize the forming of the PC insulating plate.
[0004] However, when the existing forming die is used to prepare the PC insulating plate, the heating of the heating medium by the electric heater can cause convection of the heating medium, so that the temperature of the heating medium at different positions is different, and thus the temperature of the die seat at different positions is different. At the same time, since the material of the PC insulating plate belongs to a high polymer material, it is sensitive to temperature changes, so that the die seat with different temperatures at different positions can easily cause the forming size of the PC insulating plate to deviate, and thus the forming quality of the PC insulating plate is affected.

A heating box body 3 is fixedly installed inside the mounting seat 1, and the heating box body 3 is filled with a heating medium. In the embodiment, the heating medium is heat conducting oil. A heating assembly 4 is arranged inside the heating box body 3, and a heat conduction assembly 5 is arranged on the heating box body 3.
[0033] Referring to Figure 2 and Figure 3The heating assembly 4 comprises a first heating plate 41, a second heating plate 42 and a heating pipe 43. The first heating plate 41 is fixedly installed on the inner bottom wall of the heating box body 3. The second heating plate 42 is fixedly placed above the first heating plate 41. A plurality of insertion columns 7 are fixedly arranged on the outer circle of the side of the second heating plate 42 facing the first heating plate 41. A plurality of insertion holes 8 are formed on the side of the first heating plate 41 facing the second heating plate 42, and each insertion column 7 is inserted into one insertion hole 8.

In this embodiment, the heating pipe 43 comprises a plurality of parallel pipe segments. The plurality of pipe segments are sequentially connected end to end, and the connection between the adjacent two pipe segments is arc-shaped.
[0034] With reference to Figure 2 and Figure 3 In the forming process of the PC insulation board, the heating pipe 43 is electrically connected with the external power supply, so that the first heating plate 41 and the second heating plate 42 are heated by the heating pipe 43. The first heating plate 41 and the second heating plate 42 heat the heating medium in the heating box body 3 after being heated. The shape of the heating pipe 43 helps to increase the contact area of the first heating plate 41 and the second heating plate 42 with the heating pipe 43, thereby improving the heating effect of the heating pipe 43 on the first heating plate 41 and the second heating plate 42, and further improving the heating effect on the heating medium.

The side of the heat conduction fins 53 away from the heat conduction plate 51 is inserted into the heating box 3.
[0038] With reference to Figure 2 and Figure 4 When the heating medium is heated, the heat in the heating medium is conducted to the heat conduction plate 51 through the heat conduction fins 53, and then is uniformly conducted to the mold base 2 through the heat conduction film 52, thereby helping to improve the uniformity of the temperature of the mold base 2 at different positions during the forming of the PC insulation board, and further helping to improve the forming precision of the PC insulation board in the mold base 2, and ensuring the forming quality of the PC insulation board.

[0041] The implementation principle of the embodiment is that, during the forming of the PC insulation board, the heating pipe 43 is electrically connected to the external power supply, so that the heating pipe 43 is used to heat the first heating plate 41 and the second heating plate 42, and the first heating plate 41 and the second heating plate 42 heat the heating medium in the heating box 3 after being heated.
[0042] During the heating of the heating medium, the heat insulation plate 11 helps to block the heat in the heating box 3 from being lost, thereby helping to improve the heat preservation effect of the heating box 3, and further helping to improve the heating effect of the heating medium.
[0043] When the heating medium is heated, the heat in the heating medium is conducted to the heat conduction plate 51 through the plurality of heat conduction teeth 53, the heat transferred to the heat conduction plate 51 is uniformly conducted to the mold base 2 through the heat equalizing film 52, thereby helping to improve the uniformity of the temperature of each position of the mold base 2 when the PC insulation board is formed, and further helping to improve the forming precision of the PC insulation board in the mold base 2, thereby ensuring the forming quality of the PC insulation board.
[0044] The plurality of heat conduction teeth 53 arranged at equal distances help to improve the speed of the heat conduction teeth 53 to conduct the heat of the heated heating medium to the heat conduction plate 51, and help to improve the uniformity of the heat conducted by the heat conduction teeth 53 to the heat conduction plate 51, thereby helping to improve the uniformity of the temperature of each position of the heat conduction plate 51, and further improving the uniformity of the heat conducted to the mold base 2.
