[0002] The oil dipstick plastic part is a key component in the automobile engine oil system. It is used to measure the liquid level of the lubricating oil. The oil dipstick plastic part not only helps the driver check and maintain the normal level of the engine lubricating oil, but also helps to detect potential engine problems in time. Therefore, the oil dipstick plastic part is particularly important during processing.

[0003] The mold for processing the oil dipstick plastic part needs to be disassembled frequently during use in order to clean the inside of the mold. In order to improve the operating efficiency, most existing molds for processing the oil dipstick plastic part use the combination of springs and latches to improve the operating efficiency. Although this method is convenient for disassembly, the method of using multiple springs and latches at the same time is difficult for one person to disassemble. The latch will rebound due to the tension of the spring, so it is necessary to pull multiple latches at the same time to disassemble. Utility Model Content
