[0025] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 In this embodiment of the utility model, a large-scale integrated die-casting process special hot work mold steel includes a hot work mold steel plate 1 and a holding rack 6; the hot work mold steel plate 1 is composed of a plate body 2 and a lifting assembly 3, the lifting assembly 3 is welded to both sides of the plate body 2, the holding rack 6 is composed of a base 9 and a support plate 8, the support plate 8 is welded to both sides of the upper end of the base 9, a groove is provided in the middle of the support plate 8, the hot work mold steel plate 1 is placed on the upper side of the base 9 in the middle of the support, and a pad 7 is placed between the hot work mold steel plates 1, the two ends of the pad 7 are inserted into the groove in the middle of the support plate 8.

[0026] Wear-resistant rubber pads 12 are provided on the outer side of the pad 7. The wear-resistant rubber pads 12 are attached to the upper and lower ends of the pad 7 with adhesive. In large-scale integrated die casting processes, when hot work die steel plates 1 are stacked, the rubber pads can utilize their elasticity and wear resistance to buffer the pressure between the steel plates, reducing wear caused by vibration or slight movement. At the same time, the rubber material has a certain degree of heat insulation, which can reduce heat transfer between adjacent steel plates to a certain extent, protecting the performance of the die steel plates. Stop bars 11 are provided at both ends of the pad 7. The stop bars 11 are integrally set with the pad 7. When the pad 7 is inserted into the groove of the support plate 8, the stop bars 11 can abut against the side of the support plate 8, acting as a blocking force to prevent the pad 7 from sliding axially within the groove. This ensures that the pad 7 provides stable and reliable separation and support for the hot work die steel plates 1, avoiding instability in the steel plate stacking due to pad 7 displacement.

[0027] A triangular plate 10 is provided between the support plate 8 and the base 9. The triangular plate 10 is welded to the outside of the support plate 8 and the upper side of the base 9. The triangular plate 10 welded between the support plate 8 and the base 9 utilizes the stability of the triangular structure to significantly enhance the firmness of the connection between the support plate 8 and the base 9. In the large-scale integrated die-casting process, the rack 6 needs to bear the heavy hot work mold steel plate 1. The triangular plate 10 can effectively distribute the pressure borne by the support plate 8, prevent the support plate 8 from deforming or breaking due to excessive force, ensure the overall structural stability of the rack 6, and extend its service life.

[0028] The lifting assembly 3 consists of lifting rods 5 and limiting plates 4. The lifting rods 5 are welded to both sides of the plate 2, and the limiting plates 4 are welded to one side of the lifting rods 5. The lifting rods 5 welded to both sides of the hot work die steel plate 1 are the connection points of the lifting equipment. The entire plate 2 can be lifted smoothly through the lifting rods 5. The limiting plates 4 welded to one side of the lifting rods 5 can limit the position of the lifting slings during the lifting process, prevent the slings from sliding on the lifting rods 5, ensure the safety and stability of the lifting process, avoid the plate 2 from tilting or falling due to the displacement of the slings, and ensure operational safety and the integrity of the die steel plate.

[0029] The outer side of the display rack 6 is provided with a wear-resistant layer 13, which is a chrome-plated layer. The chrome-plated layer on the outer side of the display rack 6 serves as the wear-resistant layer 13. In the workshop environment of large-scale integrated die casting process, it can effectively improve the surface hardness and wear resistance of the display rack 6, resist the collision, friction and corrosion of the environment during daily use. This not only keeps the appearance of the display rack 6 intact, but also extends its service life and ensures that it can stably support the hot work die steel plate 1 for a long time.

[0030] The working principle and usage process of this utility model are as follows: The hot work die steel plate 1 is the core working component. The plate 2 directly participates in the high-temperature die casting process and bears huge thermal shock and mechanical stress. The lifting components 3 welded on both sides are to meet the lifting requirements of the die steel plate during production, transportation and installation. The heavy plate 2 can be moved and positioned stably through the lifting components 3. The base 9 of the holding rack 6 provides stable support for the overall structure and prevents the die steel plate from tipping over when it is placed. The support plates 8 on both sides play a limiting role, accurately limiting the hot work die steel plate 1 to the middle position of the support on the upper side of the base 9, avoiding lateral displacement of the plate during storage or transportation. The pads 7 placed between the hot work die steel plates 1 can effectively separate the plates and prevent them from directly contacting each other and causing friction damage. At the same time, the two ends of the pads 7 are inserted into the grooves in the middle of the support plates 8, which further enhances the stability of the pads 7 and ensures that the plates remain neat and orderly in the stacked state, providing convenience for subsequent use and management.
