Description

Technical Field

[0001] This utility model relates to the field of hot pressing molding machine technology, and in particular to a hot pressing molding machine for graphene composite materials. Background Technology

[0002] As is known, graphene composite materials refer to composite materials made by combining graphene with other materials. Existing graphene composite material hot press molding machines extrude the material by bringing an upper die and a lower die close together. To facilitate the placement of material on the lower die, a slide rail is installed on the base of the hot press molding machine. After the material is placed on the lower die, it slides along the slide rail to the corresponding position. Then, the material is extruded by bringing the upper die close to the lower die. However, when the material is unevenly piled, the material extends along the lower die when the upper die is pressed down. Due to the uneven material pile, the lower die is subjected to unstable horizontal force during the extension. During the pressing process of the upper die, the lower die slides, causing misalignment between the upper and lower dies, which reduces the yield of the finished product. Therefore, a graphene composite material hot press molding machine is proposed. Utility Model Content

[0024] like Figures 2-5 As shown, the gear 8 is provided with protrusions 11, and the protrusions 11 on the gear 8 are evenly distributed on the lower surface of the gear 8. The molding machine base 1 is provided with a vibration column 12, one end of the vibration column 12 is fixedly connected to the upper surface of the molding machine base 1. The gear 8 drives the protrusions 11 to rotate around the rotating shaft 9. The protrusions 11 and the vibration column 12 are interference-fitted. The gear 8 bounces up and touches the lower mold base 3 to generate vibration.

[0025] like Figure 3 , Figure 4 and Figure 6 As shown, the gear lock consists of a gear lock base 13, a locking block 14, a locking rack 15, a first elastic telescopic rod 16, a sliding column 18, and a pressure plate 19. The lower surface of the gear lock base 13 is connected to the upper surface of the molding machine base 1, and the gear lock base 13 has a cavity inside. The gear lock base 13 has a locking hole on the side near the gear 8, and a locking block 14 is installed in the locking hole of the gear lock base 13. The locking block 14 is slidably connected to the gear lock base 13. A locking rack 15 is fixedly connected to the side of the locking block 14 near the gear 8, and the locking rack 15 meshes with the gear 8. The side of the gear 14 away from the gear 8 is connected to the inner wall of the gear lock base 13 away from the gear 8 through the first elastic telescopic rod 16. The upper surface of the gear lock base 13 is provided with a sliding column hole, and a sliding column 18 is provided in the sliding column hole of the gear lock base 13. The sliding column 18 is slidably connected to the gear lock base 13. The top end of the sliding column 18 is connected to the lower surface of the pressure plate 19. The upper surface of the pressure plate 19 is in contact with the upper mold base 5. The bottom end of the sliding column 18 is inclined near the lock block 14. The side of the sliding column 18 away from the lock block 14 is in contact with the inner wall of the gear lock base 13.

[0026] like Figure 3 , Figure 4 and Figure 6 As shown, the pressure plate 19 is provided with a second elastic telescopic rod 17. One end of the second elastic telescopic rod 17 is fixedly connected to the lower surface of the pressure plate 19, and the other end of the second elastic telescopic rod 17 is fixedly connected to the upper surface of the gear lock base 13.

[0027] like Figure 3 , Figure 4 and Figure 6 As shown, there are two first elastic telescopic rods 16, which are located on both sides of the sliding column 18.

[0028] like Figure 3 , Figure 4 and Figure 6 As shown, there are two second elastic telescopic rods 17, which are located on both sides of the sliding column 18.

[0029] like Figure 1 As shown, there are two locking devices, which are located on both sides of the lower mold base 3.

[0030] The work process is as follows:

[0031] S1. When in use, the required material is placed on the lower mold base 3. The lower mold base 3 is started to slide. The rack 10 set on the lower mold base 3 drives the gear 8 to rotate. The protrusion 11 set on the gear 8 touches the vibrating column 12, causing the gear 8 to bounce up and hit the lower mold base 3 to generate vibration. The vibration makes the material more evenly dispersed.

[0032] S2, when the lower mold base 3 slides to the corresponding position, the hydraulic cylinder 6 is activated, and the upper mold base 5 begins to press down. The upper mold base 5 presses down and touches the pressure plate 19. The pressure plate 19 drives the sliding column 18 to press down and push the locking block 14. The locking block 14 pushes the locking rack 15 to lock the gear 8. The lower mold base 3 is fixed by the locking gear 8, so as to prevent the lower mold base 3 from sliding and causing misalignment of the upper and lower molds during the pressing process.

[0033] S3, start the upper mold base 5 to lift, the first elastic telescopic rod 16 and the second elastic telescopic rod 17 return to their original positions, and the locking state is released.

[0034] S4, the lower mold base 3 slides out, the rack 10 on the lower mold base 3 drives the gear 8 to rotate, the protrusion 11 on the gear 8 touches the vibration column 12, causing the gear 8 to bounce up and hit the lower mold base 3 to generate vibration, and the finished product is easier to demold through vibration.

[0035] To reduce manual operation and improve the stability of the locking device, two first elastic telescopic rods 16 are provided, located on both sides of the sliding column 18. The side of the locking block 14 away from the gear 8 is connected to the inner wall of the gear lock base 13 away from the gear 8 through the first elastic telescopic rods 16. This makes the locking block 14 more evenly stressed and the locking and unlocking process more stable. To improve the stability of the reset, two second elastic telescopic rods 17 are provided, located on both sides of the sliding column 18. The lower surface of the pressure plate 19 is connected to the upper surface of the gear lock base 13 through the second elastic telescopic rods 17. Of course, multiple locking devices can be provided to lock the lower mold base 3 precisely. For example, two locking devices can be provided and located on both sides of the lower mold base 3. Considering that the locking devices need to be set in pairs during actual operation and are symmetrically arranged, the locking stability is further improved.

[0036] When the material used in the processing of graphene composite materials is powder, the lower surface of gear 8 is provided with protrusions 11, and the protrusions 11 on gear 8 are evenly distributed on the lower surface of gear 8. The molding machine base 1 is provided with a vibration column 12. One end of the vibration column 12 is fixedly connected to the upper surface of the molding machine base 1, and the other end of the vibration column 12 contacts the protrusions 11 on gear 8. The vibration column 12 and the protrusions 11 on gear 8 form an interference fit. When the lower mold base 3 slides inward along the slide 2, the rack 10 provided on the side of the lower mold base 3 will drive gear 8 to rotate around the rotating shaft 9. At this time, the protrusions 11 on the lower surface of gear 8 generate frictional vibration with the vibration column 12 provided on the molding machine base 1 through the interference fit during the rotation, thereby transmitting the vibration to the material through the lower mold base 3 so that the powder material is more evenly distributed through vibration.
