Description

Technical Field

[0001] The utility model belongs to the technical field of automobile production molds, in particular to a mold for automobile door production with a cooling function. Background Art

[0002] The car door is part of the car body structure. It is located on the side of the vehicle and provides a passage for passengers to enter and exit the vehicle. Car doors are usually made of metal and have a solid outer shell and internal structure to ensure its safety and stability during vehicle driving and collision. The mold system for car door production with cooling function may include components such as cooling tanks, liquid inlet pipes and liquid outlet pipes. The cooling tank is designed at the key part of the mold to directly contact and cool the injection molded parts; the liquid inlet pipe and liquid outlet pipe are responsible for the circulation of the coolant to ensure uniform and efficient cooling. By arranging these components reasonably, the mold can maintain the appropriate temperature during the injection molding process, thereby preventing product deformation, warping or other quality problems.

[0003] Publication No. "CN210996091U" A mold for producing automobile door beams with a cooling function, including a water pump, a trigger button, an air guide groove, a water guide pipe, a water spray seat, a water outlet seat and a spray head. A water pump is installed on the upper end face of the mold body, a water guide pipe is installed inside the upper pressure plate, a trigger button is installed on the front side of the lower end face of the upper pressure plate, water spray seats are installed on the left and right sides of the lower end face of the upper pressure plate, a water outlet seat is installed on the right side of the water spray seat, a spray head is installed inside the water outlet seat, and air guide grooves are provided on the left and right sides of the lower mold body. This design solves the problem that the original automobile door beam production does not have a cooling function. The utility model has a reasonable structure, which is convenient for improving the effect of rapid cooling during the stamping production process of automobile door beams.

[0004] Although the above utility model has a reasonable structure and is convenient for improving the rapid cooling effect during the stamping production process of automobile door beams, when cooling the workpiece, the sprayed cooling water may not be completely vaporized. Part of the water may evaporate into water vapor, while the other part may flow away or remain in the lower mold in liquid form. The long-term contact between the cooling water and the lower mold may cause metal corrosion, which will affect the precision and service life of the mold and increase the maintenance cost of the mold. At the same time, the water in the lower mold will evaporate after heating, causing the mold temperature to fluctuate. This temperature instability will affect the stamping performance of the material and the molding accuracy of the product, and may make the results of each stamping inconsistent.
