Description

Technical Field

[0001] The utility model relates to the technical field of automobile tray forming molds, in particular to an automobile tray forming mold. Background Art

[0002] With the development of society, people have higher and higher requirements for means of transportation. The rise of cars is an inevitable demand for social development. With the continuous development of cars, the requirements for various aspects of car performance are becoming higher and higher. Car pallets are one of the most important accessories for electric vehicles. In order to ensure safe load-bearing, car pallets must meet the requirements of high strength and good rigidity. Molds are a kind of production tools that can also give products complete structures and precise dimensions. Molds are needed in the process of mass production of pallets. For example, the Chinese utility model patent with patent number CN205519257U discloses a forming die for an automobile pallet. The conventional die is used to firstly form a convex bulge with a larger diameter and a lower height on the automobile pallet. Then, the die of the utility model is used to further form the automobile pallet, so that the elastic range of the convex bulge is increased, the stretchable range is increased, and the convex bulge flows better during the further stretching process, thereby avoiding the convex bulge from wrinkling or cracking during the stretching process. While ensuring that the thickness of the automobile pallet does not become excessively thin, the convex bulge shape on the convex bulge is raised to form a small convex bulge with a higher height and a smaller area, and finally formed into a convex bulge contour with a conical surface. The height and contour size of the convex bulge of the part are of stable quality, and the structure is simple, which is more suitable for adding a simple automation device to realize automated production.

[0003] There are still some problems in the use of the above devices. The automobile pallet needs to be as light as possible and have good heat dissipation without affecting the strength and rigidity. Therefore, it is usually necessary to punch holes on the pallet to reduce the weight of the pallet and improve the heat dissipation effect. The existing forming molds cannot meet the forming requirements in production and can only meet the shaping requirements. When punching holes on the pallet, other punching equipment is required for secondary operations, which is inefficient in production. Utility Model Content

[0004] In view of the above technical problems, the utility model provides a car pallet forming mold, which is characterized by being composed of a base structure, a lower die set, a hydraulic column, a top structure, and an upper die set. The lower die set is installed above the base, hydraulic columns are installed at the four corners above the base, the upper die set is installed at the top of the hydraulic column, and the lower die set is installed at the lower side of the upper die set.

[0005] The base structure is composed of a base and a feed hole, and a plurality of feed holes are provided inside the base.

[0010] The top end of the punching column is conical.

[0011] Beneficial effects of the utility model:

[0012] The utility model discloses a forming die for an automobile pallet. A top plate is pressed down and squeezed into a forming groove. The plate to be processed is finalized, and a punching column is installed on a mounting plate. The top end of the punching column is conical. When the top plate is pressed down, the top plate squeezes a spring, and the force generated makes the punching column penetrate the plate to be processed to complete the punching. At this time, waste materials fall out along the reserved holes and the feeding holes, and the punching and forming of the pallet can be completed. BRIEF DESCRIPTION OF THE DRAWINGS
