[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a cooling circuit device for an injection mold of a vehicle lamp bracket, comprising a shock absorbing mechanism 1, and a cooling mechanism 2 is fixedly installed on the top of the shock absorbing mechanism 1;

[0025] The cooling mechanism 2 includes a support plate 201, four support columns 202 are fixedly installed on the top of the support plate 201, a fixed mold 203 is fixedly installed between the tops of the four support columns 202, a hole 3 204 is provided at the bottom of the inner wall of the fixed mold 203, a hydraulic cylinder 205 is fixedly installed on the top of the support plate 201, a piston rod 206 is provided at the output end of the hydraulic cylinder 205, a push plate 207 is fixedly installed on the top of the piston rod 206, a group of threaded holes 1 208 is provided on the outer wall of the fixed mold 203, a water cooling box 209 is provided on the top of the support plate 201, a water cooling pipe 210 is fixedly connected to the top of the water cooling box 209, a water pump 211 is provided on the outer wall of the water cooling pipe 210, a group of fixing rings 212 are fixedly installed on the outer wall of the fixed mold 203, a group of fixing rings 212 are provided on the outer wall with threaded holes 213, and a group of threaded holes 213 are threadedly connected to the inner wall with screws 214.

[0026] The effect achieved by the entire embodiment 1 is that, first, the operation of the water pump 211 can extract the water-cooling liquid in the water-cooling box 209, and circulate it through the water-cooling pipe 210 to cool the mold in the fixed mold 203, which can reduce the thermal stress of the mold during operation, reduce the risk of wear and deformation of the mold, and thus extend the service life of the mold. Reasonable cooling design can reduce cracks and damage to the mold caused by thermal fatigue and improve the durability of the mold. Secondly, the operation of the hydraulic cylinder 205 drives the piston rod 206 to extend and retract, thereby moving the push plate 207 upward to eject the mold, thereby achieving rapid ejection of the mold and reducing the possibility of operational errors.

[0027] Embodiment 2, as Figure 2-Figure 4 As shown, the shock absorbing mechanism 1 includes a base plate 101, four springs 102 are fixedly installed on the top of the base plate 101, and dampers 103 are fixedly installed on the inner walls of the four springs 102. A support plate 104 is fixedly installed between the tops of the four springs 102, and a support frame 105 is fixedly installed on the top of the support plate 104. Two holes 106 are provided on the top of the support frame 105, and two hydraulic cylinders 107 are fixedly installed on the top of the support frame 105. Piston rods 108 are provided at the output ends of the two hydraulic cylinders 107, and a movable mold 109 is fixedly installed between the bottoms of the two piston rods 108. An injection port 110 is provided on the top of the movable mold 109, and a hole 2 111 is provided on the top of the support frame 105. The top of the support plate 104 is fixedly connected to the bottom of the support plate 2 201.

[0028] The effect achieved by the entire embodiment 2 is that when the device is used normally, the four springs 102 cooperate with the four dampers 103 to enable the cooling circuit device to work more stably, reducing production interruptions and maintenance time caused by vibration, which helps to improve production efficiency and ensure the smooth production of the headlight bracket. Secondly, after the mold is formed, the movable mold 109 is moved upward by the operation of the hydraulic cylinder 107, which makes it convenient for the staff to take the mold.

[0029] Among them, the damper 103, the hydraulic cylinder 1 107, the hydraulic cylinder 2 205 and the water pump 211 are all existing technologies, and their components and operating principles are all public technologies, and no further explanation is given here.

[0030] Working principle: First, when the device is used normally, the bottom of the support plate 104 is connected to the four springs 102, which can help improve production efficiency and ensure the smooth production of the headlight bracket. The movable mold 109 is in contact with the fixed mold 203. The top of the movable mold 109 is provided with an injection port 110. The heated plastic is injected into the fixed mold 203 through the injection port 110 to perform mold forming processing. Secondly, the two hydraulic cylinders 107 are connected to the two piston rods 108. The two piston rods 108 are fixedly connected to the movable mold 109. When the two hydraulic cylinders 107 are running at the same time, the two piston rods 108 are driven to extend and retract, so that the movable mold 109 can be moved upward after the mold is formed, which is convenient for taking the mold. The top of the water cooling box 209 is fixedly connected with a water cooling pipe 210. The outer wall of the water cooling pipe 210 is provided with a water pump 211. At the same time, the water cooling pipe 210 is fixed to the fixed mold 203 by a fixing ring 212 and passes through the screws 214 at the same time. The threaded hole 1 208 and the threaded hole 213 connect the fixing ring 212 to the fixed mold 203, and the water pump 211 is running to circulate the water-cooling liquid in the water-cooling box 209 in the water-cooling pipe 210, which can be controlled more accurately, thereby ensuring that the headlight bracket shrinks evenly during the cooling process, reducing the risk of deformation and warping, and helping to keep the mold working within a reasonable temperature range, reducing fatigue, deformation, cracks and oxidation of the mold caused by long-term high-temperature operation. This can not only extend the service life of the mold, but also reduce production interruptions and maintenance costs caused by mold damage. Secondly, the hydraulic cylinder 205 is connected to the push plate 207 through the piston rod 206. When the hydraulic cylinder 205 is running, it drives the piston rod 206 to extend and retract, thereby driving the push plate 207 to move upward, and the mold is ejected upward, which can reduce the force impact of the mold during the ejection process, reduce the wear and fatigue of the mold, which helps to extend the service life of the mold and reduce the frequency and cost of mold replacement.
