[0021] See also Figure 1-3 , an injection mold with a cooling function, comprising a cooling machine 1, wherein a shock absorbing device 2 is arranged inside the cooling machine 1; the shock absorbing device 2 comprises an outer frame 21, wherein a liquid capsule 22 is fixedly connected inside the outer frame 21, wherein the liquid inside the liquid capsule 22 is designed to be in a saturated state in an initial state and the liquid capsule 22 is designed as a whole to be made of nylon, and this design makes the overall anti-vibration effect of the liquid capsule 22 better, wherein a hydraulic cylinder 1 23 is fixedly connected to the side of the liquid capsule 22, wherein a hydraulic cylinder 2 24 is fixedly connected to the inner side of the outer frame 21, wherein hydraulic rods 25 are slidably connected to the inner parts of the hydraulic cylinders 1 23 and 24, wherein the top and the bottom of the hydraulic rods 25 are fixedly connected to the inner parts of the hydraulic cylinders 1 23 and 24 by springs, and wherein a hollow groove is provided inside the hydraulic rods 25 26, the hollow groove 26 is rotatably connected to a rotating wheel 27, a torsion spring is provided on the front of the rotating wheel 27 and the other side of the torsion spring is fixedly connected to the inside of the hydraulic rod 25. This design allows the torsion spring to drive the rotating wheel 27 back to its initial position when the baffle 28 is not squeezed, and a baffle 28 is fixedly connected to the side of the rotating wheel 27. The interior of the shock absorbing device 2 is provided with a plurality of hydraulic cylinders 1 23, hydraulic cylinders 24, hydraulic rods 25, hollow grooves 28, rotating wheels 27 and baffles 28. When the cooler 1 starts to operate, violent vibrations will be generated, so that the vibration force is transmitted to the inside of the outer frame 21, so that the liquid inside the hydraulic cylinders 1 23 and the hydraulic cylinders 24 will flow into the inside of the liquid bag 22 and expand the liquid bag 22, thereby achieving the effect of protecting the internal cooler 1 from being damaged by vibration.

[0022] During use, when the cooler 1 starts to operate, it will generate violent vibrations, which will transmit the vibration force to the inside of the outer frame 21, causing the hydraulic rod 25 to slide toward the inside of the hydraulic cylinder 1 23 and the hydraulic cylinder 2 24 and squeeze the springs at the top and bottom of the hydraulic rod 25. When the hydraulic rod 25 slides, the baffle 28 inside the hollow groove 26 will be squeezed and start to rotate through the rotating wheel 27, so that when the rotating wheel 27 rotates, the internal torsion spring will be stretched, thereby reducing a lot of vibrations, and the liquid inside the hydraulic cylinder 1 23 and the hydraulic cylinder 24 will flow into the liquid bag 22 and expand the liquid bag 22, thereby protecting the internal cooler 1 from being damaged by vibration.

The bottom of the squeezing ball 32 is fixedly connected to the inside of the rod body 31 by a spring, and the spring is in a relaxed state in the initial state. A plurality of squeezing balls 32 are slidably connected inside the rod body 31. When the hydraulic rod 25 slides into the inside of the hydraulic cylinder 1 23 and the hydraulic cylinder 2 24, the squeezing ball 32 on the side of the rod body 31 is squeezed, so that the squeezing ball 32 slides after being squeezed and squeezes the spring at the bottom of the squeezing ball 32 and slides into the inside of the hydraulic rod 25, thereby achieving the effect of reducing part of the vibration force when the hydraulic rod 25 slides.

[0025] During use, based on the first embodiment, when the hydraulic rod 25 slides toward the inside of the hydraulic cylinder 1 23 and the hydraulic cylinder 2 24, it will squeeze the squeezing ball 32 on the side of the rod body 31, so that the squeezing ball 32 is squeezed and slides and squeezes the spring at the bottom of the squeezing ball 32 and slides toward the inside of the hydraulic rod 25, thereby achieving the effect of reducing some of the vibration force when the hydraulic rod 25 slides.
