[0002] Automobile injection mold is a tool for producing automobile plastic parts; it is also a tool that gives plastic products a complete structure and precise size. Injection molding is also called injection molding, which is a molding method of injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as complex-shaped products. When the existing automobile injection mold is injected, it is usually necessary to cool and demold in the later stage. Generally, water cooling is used for cooling and demolding. However, in the existing automobile injection mold, most of them use a layer of pipes to transport water for cooling, which leads to certain limitations in the flow position of water in the automobile injection mold. It is impossible to fully transport water in the automobile injection mold, so that the automobile injection mold cannot be fully water-cooled, resulting in poor local heat dissipation effect, and finally the demolding effect is not good enough, affecting product quality.

[0029] Embodiment 2:

[0030] See also Figure 5-6In this embodiment, the lower leakage component 8 includes a pressing plate 801, a supporting rod 802, and an L-shaped plate 803. The inner part of the return pipe 701 is slidably connected with the pressing plate 801, and the surface of the pressing plate 801 is installed with the supporting rod 802.

[0031] When the injection mold body 1 is water-cooled, water is transported to the first water transport pipe 2 through the water inlet pipe 6. The water transport is a mature existing technology, and the patent publication: CN210851210U can be referred to. When multi-layer water transport is adopted, the hydraulic rod 704 is first started. At this time, the output end of the hydraulic rod 704 drives the sawtooth disk 1 705 to move the position, so that the sawtooth disk 1 705 is meshed with the sawtooth disk 2 707.

At this time, as the water is continuously transported, the water on the pressure plate 801 continues to increase, and the gravity continues to increase. When the gravity is greater than the elastic force of the compression spring 804, the pressure plate 801 drives the support rod 802 to move downward, and the support rod 802 squeezes the compression spring 804 in the slide groove provided on the surface of the L-shaped plate 803, so that the pressure plate 801 is separated from the return pipe 701, and the water flows out along the lower leakage groove, thereby carrying out single-layer water transportation, facilitating single-layer water transportation, and making it easy to operate during single-layer water transportation, further improving the operating efficiency of the device.
