Description

Technical Field

[0001] This utility model belongs to the field of die casting mold technology, and specifically relates to a die casting mold with a protective structure. Background Technology

[0002] Die casting molds are tools used to cast metal parts. They are tools used to complete the die casting process on a special die casting and forging machine. The basic process of die casting is as follows: molten metal is first cast into the cavity of the mold at low or high speed. The mold has movable cavity surfaces. As the molten metal cools, it is pressurized and forged, which not only eliminates shrinkage cavities and porosity defects in the blank, but also makes the internal structure of the blank reach the forged state of broken grains, and the comprehensive mechanical properties of the blank are significantly improved.

[0003] Currently, to prevent die-casting molds from being damaged by collisions during transportation, most methods involve installing protective covers on the outside of the die-casting mold to prevent it from being impacted during transport. For example, a die-casting mold with a protective structure is disclosed in Chinese Patent Publication No. CN220901869U. However, the fixing structure of the protective cover is cumbersome to operate, which makes it difficult to disassemble and assemble the protective cover. Utility Model Content

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] like Figures 1 to 11As shown, a die-casting mold with a protective structure includes a base plate 1. A lower mold 2 is fixedly connected to the upper surface of the base plate 1. An upper mold 3 is fitted onto the upper surface of the lower mold 2. A first positioning ring 4 is fixedly connected to the upper surface of the base plate 1. A protective cover 5 is fitted onto both the surface of the first positioning ring 4 and the upper surface of the base plate 1. A limit post 6 is fixedly connected to the inner wall of the protective cover 5. The bottom of the limit post 6 is fitted onto the upper surface of the upper mold 3. A limit ring 7 is fitted onto the surface of the upper mold 3. A connecting post 8 is fixedly connected to both the upper surface of the limit ring 7 and the inner wall of the protective cover 5. Sliding sleeves 9 are fixedly connected to both the left and right sides of the protective cover 5. A first U-shaped post 10 is fitted onto the inner wall of the sliding sleeve 9. A rectangular hole 11 is opened at the bottom of the sliding sleeve 9. An L-shaped locking post 12 is fixedly connected to the bottom of the first U-shaped post 10. The left and right sides of the L-shaped locking post 12 are fitted onto the rectangular hole 11. The inner wall of the base plate 1 is fitted with a second U-shaped post 13, the bottom of the second U-shaped post 13 is fixedly connected to the upper surface of the base plate 1, the front of the first U-shaped post 10 is fixedly connected with a hollow block 14, the inner wall of the hollow block 14 is fitted with a bolt 15, the surface of the bolt 15 is threadedly connected with a threaded cylinder 16, the surface of the threaded cylinder 16 and the upper surface of the base plate 1 are both fixedly connected with connecting blocks 17, the inner wall of the second U-shaped post 13 and the upper surface of the base plate 1 are both fixedly connected with limiting blocks 18, the upper surface of the limiting blocks 18 is fitted with the bottom of the L-shaped post 12, the surface of the bolt 15, the bottom of the hollow block 14 and the upper surface of the threaded cylinder 16 are all fitted with elastic sealing sleeves 25, the surface of the elastic sealing sleeve 25 is fitted with a second positioning ring 28, the upper surface of the second positioning ring 28 is fixedly connected to the bottom of the hollow block 14.

[0032] It should be noted that after the protective cover 5 is fixed on the base plate 1, the upper mold 3 can be fixed on the lower mold 2 through the cooperation of the limiting post 6, the connecting post 8 and the limiting ring 7. When the first U-shaped post 10 slides back and forth in the sliding sleeve 9, the L-shaped locking post 12 can slide back and forth in the rectangular hole 11. When the L-shaped locking post 12 contacts the second U-shaped post 13, the protective cover 5 can be fixed on the base plate 1 through the cooperation of the L-shaped locking post 12, the second U-shaped post 13 and the first positioning ring 4. When the L-shaped locking post 12 separates from the second U-shaped post 13, the protective cover 5 can be directly separated from the base plate 1.

[0033] When the L-shaped locking post 12 contacts the second U-shaped post 13, the limiting block 18 can prevent the L-shaped locking post 12 from deforming when the protective cover 5 is subjected to an upward force. The elastic sealing sleeve 25 can seal the connection between the threaded cylinder 16 and the bolt 15, thereby preventing the bolt 15 from being unable to be smoothly unscrewed from the threaded cylinder 16 due to rust at the connection between the threaded cylinder 16 and the bolt 15. When the elastic sealing sleeve 25 is inserted into the second positioning ring 28, the second positioning ring 28 can align the elastic sealing sleeve 25 with the threaded cylinder 16.

[0034] like Figures 1 to 12 As shown, a support block 19 is fixedly connected to the front of the protective cover 5. A rubber ring 20 is attached to both the upper surface of the support block 19 and the front of the protective cover 5. A first groove 21 is formed on the front of the rubber ring 20. A column 22 is attached to the inner wall of the first groove 21. The bottom of the column 22 is fixedly connected to the upper surface of the support block 19. A vertical plate 23 is glued to the inner wall of the rubber ring 20. A marking cardboard 24 is glued to the front of the vertical plate 23. A second groove 26 is formed on the back of the vertical plate 23. A guide post 27 is attached to the inner wall of the second groove 26. The back of the guide post 27 is fixedly connected to the front of the protective cover 5.

[0035] It should be noted that when the first groove 21 contacts the column 22, the vertical plate 23 can be positioned by the cooperation of the first groove 21 and the column 22, and the vertical plate 23 is fixed on the support block 19 by the friction between the rubber ring 20, the protective cover 5 and the column 22. When the vertical plate 23 is subjected to an upward pushing force, the rubber ring 20 can be directly separated from the column 22. After the vertical plate 23 is fixed on the protective cover 5, the marking cardboard 24 allows the user to quickly know the model of the mold inside the protective cover 5 without disassembling the protective cover 5.

[0036] When the user needs to fix the protective cover 5 to the base plate 1, first place the protective cover 5 on the base plate 1 and make the surface of the first positioning ring 4 fit against the inner wall of the protective cover 5. Then, by moving the first U-shaped post 10, make the surface of the L-shaped locking post 12 contact the inner wall of the second U-shaped post 13 and align the threaded cylinder 16 with the center of the hollow block 14. Then, insert the bolt 15 into the hollow block 14 and screw the bolt 15 into the threaded cylinder 16. At this time, through the cooperation of the bolt 15 and the threaded cylinder 16, the L-shaped locking post 12 and the second U-shaped post 13 cannot be separated. And through the cooperation of the L-shaped locking post 12, the second U-shaped post 13 and the first positioning ring 4, the protective cover 5 is fixed to the base plate 1.

[0037] When the user needs to separate the protective cover 5 from the base plate 1, first, by rotating the bolt 15, the bolt 15 is separated from the threaded cylinder 16, and the bolt 15 is removed from the hollow block 14. Then, by moving the first U-shaped post 10, the L-shaped locking post 12 is separated from the second U-shaped post 13. After the L-shaped locking post 12 is separated from the second U-shaped post 13, the protective cover 5 can be directly removed from the base plate 1.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
