Description

Technical Field

[0001] This utility model relates to the field of plastic battery casing processing technology, and in particular to a plastic battery casing demolding and ejection mechanism. Background Technology

[0002] Plastic battery casings are an important component of battery systems. As battery containers and safety barriers, they play a crucial protective role. They are mainly made of materials such as polypropylene (PP), polycarbonate (PC), and ABS plastic. In the process of ejecting the battery casing, conventional devices are time-consuming and labor-intensive, making it inconvenient to quickly demold the battery casing, thus affecting the ejection effect of the device.

[0003] Existing technology CN221793678U discloses a battery pack shell injection molding equipment for easy demolding, including an injection tube, a hydraulic cylinder, an upper mold, a rack, a gear, a rotating rod, a transmission assembly, a support rod, a take-up reel, a connecting rope, a spring, a fixed plate, an ejector rod, a push plate, and a lower mold. Injection is performed through the injection tube. After the injected battery pack shell has cooled, the hydraulic cylinder is driven to contract, moving the upper mold upward, which in turn moves the rack upward, causing the gear to rotate in the opposite direction. Under the action of the rotating rod, the transmission assembly, and the support rod, the take-up reel rotates in the opposite direction, releasing the connecting rope. The force of the spring drives the fixed plate to move the ejector rod and push plate upward, lifting the cooled battery pack shell upward and moving it to the outside of the lower mold. This achieves rapid demolding of the battery pack shell after injection molding, avoiding damage to the injection molded parts and improving the ejection effect of the device.

[0004] In normal use, existing technology makes it inconvenient to adjust the force of the pusher plate pushing the battery case based on the display effect after the battery case is demolded, thus affecting the demolding effect of the battery case. Utility Model Content

[0006] To achieve the above objectives, this utility model provides a plastic battery casing demolding and ejection mechanism, including a platform and structural components. The structural components include a push plate, a lower mold, an upper mold, a block, a spring, a base plate, a base frame, a vertical rod, a drive cylinder, an adjusting component, and a moving component. The lower mold is fixedly installed on one side of the platform. The push plate is slidably connected to the platform and to the lower mold. The base frame is fixedly connected to the platform and slidably connected to the push plate. The block is fixedly connected to the push plate and slidably connected to the base frame.

The adjusting component is connected to the platform and to the base plate. The moving component is connected to the platform, and the upper mold is connected to the moving component.

[0007] The adjusting component includes an adjusting block, a frame, and a driving component. The frame is fixedly connected to the platform and is located on the side of the platform closer to the block. The adjusting block is slidably connected to the frame and fixedly connected to the base plate. The driving component is fixedly connected to the frame and connected to the adjusting block.

The driving motor is fixedly connected to the frame, and the output shaft of the driving motor is connected to the driving rod.

[0009] The movable component includes a movable cylinder and a top plate. The movable cylinder is fixedly connected to the platform and is located on the side of the platform away from the base frame. The top plate is connected to the output end of the movable cylinder and is fixedly connected to the upper mold.

[0010] The frame has a movable groove located on the side of the frame near the adjusting block and cooperating with the adjusting block.

[0011] This utility model discloses a plastic battery casing demolding and ejection mechanism. A drive motor drives a drive rod to rotate on the frame, which in turn drives an adjusting block to move on the moving groove. The adjusting block moves a base plate on the base frame, adjusting the position and height of the base plate while simultaneously compressing a spring. A drive cylinder drives a vertical rod to rise, and the spring's rebound drives the block to move a push plate on the base frame and the lower mold, causing the push plate to eject the battery casing.
