Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping part die cooling related equipment, in particular to a cooling device for a stamping die of an automobile stamping part. Background Art

[0002] Automotive stamping parts are metal stamping parts that make up automotive parts. Among automotive stamping parts, some become automotive parts directly after stamping, while the other parts need to be processed by welding, machining, painting and other processes before they can become automotive parts.

[0003] In the existing automobile stamping parts production process, stamping dies are needed. However, when automobile stamping parts are produced, the temperature of the stamping dies will rise. If the temperature is too high, the stamping dies will be deformed, affecting the production process of automobile stamping parts. When automobile stamping parts are stamped, the overall temperature of the stamping equipment will become high, and the automobile stamping parts will not be easy to demould. For this reason, a Chinese patent with application number CN202320262737.5 discloses a stamping die cooling device for automobile stamping parts. The stamping die cooling device for automobile stamping parts includes a stamping table, a lower die, an upper die, and the lower die is fixedly mounted. It is mounted on the upper surface of the base, and the upper mold is fixedly mounted on the lower surface of the upper plate. A cooling mechanism is provided on the top of the upper plate. The cooling mechanism includes a shell. A liquid storage tank is provided on the left side of the shell. A water pump is installed at the lower end of the liquid storage tank. A water pipe is provided inside the right end of the water pump. A first card slot is provided inside the upper plate. A first water-cooled plate is placed inside the first card slot. The first water-cooled plate includes a water-cooled bottom plate, a first connecting plate, and a copper elbow. A second card slot is provided inside the base. A second water-cooled plate is placed inside the second card slot. This can solve the problem of the cooling time of the cooling device inside the stamping machine being too long and the heat dissipation effect being poor. In the actual cooling process, since the two copper elbows for conveying coolant are both provided on the same side of the mold, the temperature difference between the mold side close to the copper elbow and the other opposite side is large, and thus there is a problem of uneven cooling of the stamping parts.

[0004] To this end, the utility model provides a cooling device for a stamping die of an automobile stamping part. Utility Model Content
