[0025] For better explaining the present utility model for easy understanding, the present utility model will be described in detail below in conjunction with the drawings through specific implementation manners.

[0026] Please refer to Figures 1 to 4 As shown, a lithium battery plastic suction inner support forming mold of the present utility model includes an upper template 1. Both sides of the lower surface of the upper template 1 are fixedly installed with top plates 2. One side surface of the top plate 2 is fixedly installed with a top layer 3. The lower surface of the top layer 3 is fixedly installed with a middle layer 4. The lower surface of the middle layer 4 is fixedly installed with a bottom layer 5. The middle layer 4, the top layer 3 and the bottom layer 5 form a mold core. The lower surface of the bottom layer 5 is fixedly installed with a lower template 6. An inner plastic frame 7 is provided on the inner side wall of the mold core. An air channel 8 is provided between the inner plastic frame 7 and the middle layer 4. An injection cavity 9 is provided between the upper template 1 and the lower template 6. Through grooves are opened on both sides of the middle layer 4. An adjustment component 10 is connected through the through grooves of the middle layer 4. In the actual implementation process, an external vacuum device is connected to the centralized air channel 8. The air inside the mold core is extracted by the external vacuum device to form a vacuum, so that the material adheres to the inner wall of the mold core, and finally a battery finished product is formed. After use, the upper template 1 is fastened by bolts, which can prevent the inner wall of the mold core from being damaged by external bumps and scratches. At the same time, when a certain part of the mold core is damaged, the corresponding structures of the damaged part, namely the top layer 3, the middle layer 4, and the bottom layer 5, can be replaced to reduce the mold repair cost and the mold rejection rate.

[0027] Optionally, the adjusting component 10 includes an adjusting rod 101 fixedly installed in the middle of one side of the inner plastic frame 7. A clamping block 102 is fixedly installed on the side of the adjusting rod 101 away from the inner plastic frame 7. An extension part is provided on the upper surface of the clamping block 102. A clamping groove 106 is provided on the side of the clamping block 102 away from the extension part. A threaded rod 107 is movably connected to the middle of the inner side wall of the clamping groove 106. The threaded rod 107 is connected through a fixing plate 108. A rubber washer 103 is connected through the extension part on the upper surface of the fixing plate 108. The number of rubber washers 103 is two, and they are symmetrically distributed on both sides of the clamping block 102 in a mirror image. A compression spring 104 is fixedly installed at the bottom of the inner arc surface of the rubber washer 103. A tightening cap 105 is fixedly installed on the side of the compression spring 104 away from the fixing plate 108. The tightening cap 105 is movably connected to the threaded rod 107. The number of fixing plates 108 is two, and they are symmetrically distributed on both sides of the lower template 6 in a mirror image. The number of clamping blocks 102 is four, and they are grouped in pairs. One group of clamping blocks 102 is fixedly installed on the same inner plastic frame 7. During the actual implementation process, when the staff needs to adjust and use the inner plastic frame 7, by rotating the tightening cap 105, the tightening cap 105 drives the threaded rod 107 to rotate. The threaded rod 107 is threadedly connected through the fixing plate 108. The rotation of the threaded rod 107 can move to the left side of the fixing plate 108 along the clamping block 102. The movement of the threaded rod 107 drives the adjusting rod 101 to move. The adjusting rod 101 is connected through a through groove on one side of the middle layer 4. The movement of the adjusting rod 101 drives the inner plastic frame 7 to move to the left side. The inner plastic frame 7 moves under the injection cavity 9, realizing the clamping adjustment of the cavity, facilitating combined installation, with flexible adjustment and stable fixation.
