[0022] See also Figure 1-3 The utility model provides a graphite mold with a buffer function, including a graphite lower mold 1, a graphite upper mold 2, a guide assembly 3, a first buffer assembly 4 and a second buffer assembly 5. The bottom of the graphite lower mold 1 is fixedly connected with a base 11, and the guide assembly 3 includes a guide column 31 and a guide block 32. The lower end of the guide column 31 is fixedly connected to the base 11, and the guide block 32 is fixedly connected to the side wall of the graphite upper mold 2. There are four guide columns 31 and four guide blocks 32. The four guide columns 31 are evenly distributed at the four corners of the graphite lower mold 1, and the four guide blocks 32 are evenly distributed at the four corners of the graphite upper mold 2. By setting the guide assembly 3, when the graphite upper mold 2 and the graphite lower mold 1 are closed, the graphite upper mold 2 drives the guide block 32 to slide downward along the guide column 31, which can guide the graphite upper mold 2 and improve the stability of the mold closing.

[0023] Reference Figure 1 and Figure 2The first buffer assembly 4 includes a support plate 41, a first spring 42, a cross bar 43, a sleeve 44, a second spring 45 and a support rod 46. The support plate 41 is slidably sleeved between two adjacent guide pillars 31. The first spring 42 is sleeved on the guide pillar 31, and the first spring 42 is located below the support plate 41. The cross bar 43 is fixedly installed at the bottom of the support plate 41. Both ends of the cross bar 43 are fixedly connected with a connecting plate 47, and the connecting plate 47 is fixedly connected to the bottom of the support plate 41. The sleeve 44 and the second spring 45 are sleeved on the cross bar 43. The second spring 45 abuts between two adjacent sleeves 44. The support rod 46 is hinged between the sleeve 44 and the base 11. By setting the first A buffer component 4, when the guide block 32 slides downward along the guide column 31, the guide block 32 will touch the support plate 41, causing the support plate 41 to slide downward along the guide column 31, and after squeezing the first spring 42, the elastic force of the first spring 42 is used to buffer the downward impact. At the same time, the support plate 41 will drive the cross bar 43 to descend. Since the cross bar 43 is close to the base 11, the support rod 46 is rotated, and the two sliding sleeves 44 are driven by the support rod 46 to slide relatively along the cross bar 43, squeezing the second spring 45, and the elastic force of the second spring 45 is used to buffer the impact again, thereby reducing the impact force when the mold is closed and reducing the damage to the mold.

[0024] Furthermore, guide sleeves 411 are fixedly installed at both ends of the support plate 41. The guide sleeves 411 are made of polytetrafluoroethylene. The guide sleeves 411 are slidably sleeved on the guide pillars 31. By providing the guide sleeves 411, the friction between the support plate 41 and the guide pillars 31 can be reduced, thereby extending the service life of the support plate 41.

[0025] Reference Figure 1 and Figure 3 , the four corners of the top of the graphite lower mold 1 are provided with receiving grooves 12, and the second buffer assembly 5 is located in the receiving groove 12. The second buffer assembly 5 includes a buffer rod 51 and a third spring 52. The buffer rod 51 is inserted in the receiving groove 12, and the third spring 52 is sleeved on the buffer rod 51; the upper end of the buffer rod 51 is fixedly connected with a rubber buffer pad 53. By setting the second buffer assembly 5, when the graphite upper mold 2 is about to contact the graphite lower mold 1, the graphite upper mold 2 first contacts the rubber buffer pad 53 at the upper end of the buffer rod 51, so that the buffer rod 51 is forced to move downward, and the third spring 52 is squeezed. The elastic force of the third spring 52 is used to further buffer the impact force of the graphite upper mold 2, which can reduce the impact of the graphite upper mold 2 on the graphite lower mold 1 and extend the life of the graphite mold.

[0026] The working principle and use process of the utility model are as follows: first, by setting the guide assembly 3, when the graphite upper mold 2 and the graphite lower mold 1 are closed, the graphite upper mold 2 drives the guide block 32 to slide downward along the guide column 31, which can guide the graphite upper mold 2. When the guide block 32 slides downward along the guide column 31, the guide block 32 touches the support plate 41, causing the support plate 41 to slide downward along the guide column 31, and after squeezing the first spring 42, the elastic force of the first spring 42 is used to buffer the downward impact. At the same time, the support plate 41 drives the cross bar 43 to descend. Since the cross bar 43 is close to the base 11, the support rod 46 rotates. The support rod 46 drives the two sliding sleeves 44 to slide relative to each other along the cross bar 43, squeezing the second spring 45, and using the elastic force of the second spring 45 to buffer the impact again, thereby reducing the impact force when the mold is closed and reducing mold damage. By setting the second buffer assembly 5, when the graphite upper mold 2 is about to contact the graphite lower mold 1, the graphite upper mold 2 first contacts the rubber buffer pad 53 at the upper end of the buffer rod 51, so that the buffer rod 51 is forced to move downward and squeeze the third spring 52. The elastic force of the third spring 52 is used to further buffer the impact force of the graphite upper mold 2, which can reduce the impact of the graphite upper mold 2 on the graphite lower mold 1 and extend the life of the graphite mold.
