DETAILED DESCRIPTION

[0018] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a graphite mold for rapid prototyping electronic sintering, including a workbench 1, a support leg 2 is arranged at the bottom of the workbench 1, the support leg 2 is fixedly connected to the four corners of the workbench 1, a vertical plate 3 is plugged into the workbench 1, the vertical plate 3 and the top of the heat-conducting column 7 are fixedly connected to the mold body 4, and the bottom of the heat-conducting column 7 is overlapped on the workbench 1; the vertical plate 3 is matched with the limiting device 5, so that the mold body 4 is fixed on the workbench 1, and the heat-conducting column 7 is used to transfer the heat on the mold body 4 to it, thereby increasing the contact surface with the air, so as to dissipate heat from the mold body 4.

[0020] A mold body 4 is arranged on the top of the workbench 1, and limiting devices 5 are arranged on both sides of the mold body 4. A vertical plate 3, a heat dissipation device 6 and a heat-conducting column 7 are arranged at the bottom of the mold body 4. The heat dissipation device 6 includes a protective shell 601, and the protective shell 601 is overlapped on the workbench 1, and the protective shell 601 is fixedly connected to the vertical plate 3 and the mold body 4. A connecting frame 603 is fixedly connected to the interior of the protective shell 601, and a fan 604 is fixedly connected to the connecting frame 603. An air outlet 602 is opened on one side of the protective shell 601, and a filter plate 605 is fixedly connected to the other side of the protective shell 601; the fan 604 is used to speed up the air flow speed around the heat-conducting column 7, so that the air takes away the heat on the heat-conducting column 7, thereby achieving the purpose of auxiliary cooling of the mold body 4.

[0021] The limiting device 5 includes a clamping member 501, and the clamping member 501 and the transmission rod 502 are both inserted into the mold body 4. A slider is fixedly connected to the transmission rod 502, and the slider is slidably connected in the clamping member 501. The positioning spring 504 is sleeved on the transmission rod 502, and the two ends of the positioning spring 504 are respectively fixedly connected to the clamping member 501 and the reel body 503; the elastic force of the positioning spring 504 is used to assist the clamping member 501 to be inserted into the mold body 4, thereby effectively preventing the transmission rod 502 from rotating unintentionally.

[0022] A transmission rod 502 is provided on the clamp 501, and a reel body 503 and a positioning spring 504 are provided on the transmission rod 502. The reel body 503 is fixedly connected to the transmission rod 502, one end of the main steel rope 505 is fixedly connected to the reel body 503, and the other end of the main steel rope 505 passes through the vertical plate 3 and is fixedly connected to the pull rod 506. The pull rod 506 is slidably connected in the vertical plate 3, and both ends of the pull rod 506 are fixedly connected to the auxiliary steel rope 507; the rotation of the transmission rod 502 causes one end of the main steel rope 505 to be wound around the reel body 503, and the other end of the main steel rope 505 will pull the pull rod 506 to rise.

[0023] A main steel rope 505 is provided on the reel body 503, and a pull rod 506 is provided at one end of the main steel rope 505.
