[0029] The working principle of the utility model is:

[0030] Firstly, the workbench 1 as the basic support structure of the whole device, its top with a symmetrical structure installed multiple sets of support frame 3 play a stable role, the fixed connection between the support frame 3 slide bar 4 for the subsequent movement of the moving parts to provide the basis for the guide. The second fixed block 13 and the first fixed block 10 are fixed on both sides of the top of the workbench 1, the first cylinder 12 is installed inside the second fixed block 13, and the second cylinder 17 is installed inside the first fixed block 10. At this time, each cylinder is in the initial state of inaction. The injection mechanism 7, the fixed mold 8 and the movable mold 20 and other components are in the initial position of preparation work. The protective frame 5 connected with the top of the workbench 1 is located outside the support frame 3 and the slide bar 4, and the visual window 6 on both sides of the protective frame 5 facilitates the operator to observe the internal situation, and the first cooling fan 11 inside the visual window 6 starts to operate to cool the environment in the protective frame 5 and prevent the temperature from being too high to affect the equipment. The multiple sets of support legs 2 at the bottom of the workbench 1 and the anti-skid rubber pad at the bottom ensure that the workbench 1 is stably placed on the ground, avoiding shaking and displacement during work;

[0031] Secondly, the injection mechanism 7 starts to work, and the injection material is transported to the injection pipe 27 through the feeding pipe 16. At the same time, the first cylinder 12 starts to work, and its output end pushes the movable mold 20 to move along the slide bar 4 to the fixed mold 8 until the movable mold 20 is closed with the fixed mold 8. In this process, the slide bar 4 provides accurate guidance for the movement of the movable mold 20, ensuring the stability and accuracy of the mold closing, so that the injection material is initially shaped in the closed space formed by the fixed mold 8 and the movable mold 20, forming the shape of the automobile inner plate;

[0032] Thirdly, when the injection is completed, the cooling system starts to work. The cooling tank 28 stores the cooling liquid, which flows into the first condensing pipe 19 through the water inlet pipe of the first connecting pipe 15 and flows into the second condensing pipe 22 through the water inlet pipe of the second connecting pipe 18. The cooling liquid flows in the first condensing pipe 19 and the second condensing pipe 22, absorbs the heat generated by the automobile inner plate during the injection process, and reduces the temperature of the automobile inner plate. The cooling liquid with increased temperature after absorbing heat flows back to the cooling tank 28 through the water outlet pipe of the first connecting pipe 15 and the second connecting pipe 18 respectively, so as to realize the purpose of continuously cooling the automobile inner plate;

[0033] It is worth mentioning that the multiple sets of second cooling fans 21 installed in the fixed mold 8 and the movable mold 20 start to work under the stable power supply of the power distribution block 9. The power distribution block 9 ensures that the second cooling fan 21 can work normally and stably, and the second cooling fan 21 is located at the back of the first condensing pipe 19 and the second condensing pipe 22. Its operation accelerates the air flow, discharges the hot air around the condensing pipe after absorbing heat, and further improves the cooling efficiency and accelerates the cooling speed of the automobile inner plate;

[0034] Finally, when the automobile inner plate is cooled to a certain extent, it enters the demolding process. The second cylinder 17 is started, and its output end pushes the movable block 14 to move outward. The connecting rod 23 fixedly connected with the movable block 14 moves in the movable groove 25 opened on the fixed mold 8. The movable groove 25 limits the movement track of the connecting rod 23, so that the connecting rod 23 can stably drive the pressing plate 24 to move outward. At the same time, the first cylinder 12 acts again to drive the movable mold 20 to move outward along the slide rod 4. The synchronous outward movement of the pressing plate 24 and the movable mold 20 enables the automobile inner plate cooled and formed to be quickly and stably demolded from the mold. In the demolding process, the automobile inner plate is subjected to uniform force, avoiding product deformation or damage caused by improper demolding.

[0035] The preferred embodiments of the patent are described in detail above, but the patent is not limited to the above embodiments. Various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the patent.
