[0022] See also Figure 2 The lower end of the support column 102 is located inside the guide rail 101 and is fixedly connected with a slider 104, and the slider 104 is slidably connected to the guide rail 101 through a limiting straight groove, and the cross-sectional shape of the slider 104 is circular.

[0023] See also Figure 3 A motor 105 is installed at the lower end of the slider 104, and two symmetrically distributed limit pins 109 are fixedly embedded at the upper end of the motor 105. The limit pins 109 are slidably connected to the guide rail 101 through limit straight grooves. The limit pins 109 can prevent the motor 105 from rotating.

[0024] See also Figure 2 A cantilever 106 is fixedly mounted on the upper end of the support column 102, and a gripper 107 is mounted on one end of the cantilever 106 away from the support column 102. The gripper 107 can grab the friction plate, and an electric push rod 108 is mounted inside the cantilever 106 for driving the gripper 107 to grab and release.

[0025] The working principle of automatic unloading: after the hot press machine hot-presses the friction plate in the mold, the electric push rod 103 drives the support column 102 and the gripper 107 to move to the left, and then the electric push rod 108 drives the gripper 107 to clamp the upper and lower sides of the friction plate, and the electric push rod 103 drives the support column 102 to move to the right, the motor 105 drives the support column 102 to rotate, and the gripper 107 places the friction plate on the upper side of the conveyor belt, and finally the electric push rod 108 drives the gripper 107 to open, and the conveyor belt transfers the friction plate to the next processing station, which is conducive to automatically removing the friction plate from the hot pressing mold 201, avoiding direct manual contact with the friction plate after hot pressing, and effectively improving the safety of workers.

[0026] Embodiment 2

[0027] See also Figure 4 This embodiment further explains the first embodiment. A plurality of push rods 203 equidistantly distributed around the circumference are fixedly embedded on the upper end of the disk 202, and the connection between the push rods 203 and the hot pressing mold 201 is a plug-in connection.

The lower end of the spring 204 is movably abutted against a retaining ring 205, and the connection between the retaining ring 205 and the hot pressing mold 201 is a fixed connection.

[0028] In this embodiment: when the electric push rod 103 drives the support column 102 to move to the left, the steel cable 3 is in a relaxed state. At this time, driven by the compression force of the spring 204, the disc 202 and the push rod 203 will move up inside the hot pressing mold 201, and the push rod 203 will push the friction plate in the hot pressing mold 201 to the same horizontal line as the gripping clamp 107, thereby facilitating the demoulding of the friction plate and facilitating the gripping clamp 107 to grasp the friction plate. When the support column 102 moves to the right, the steel cable 3 will pull the disc 202 to move down inside the hot pressing mold 201, facilitating the hot pressing process of the next friction plate.

[0029] Embodiment 3

[0030] See also Figure 4 This embodiment further explains Example 2. Preferably, guide pillars 4 are installed on the outer side of the steel cable 3 corresponding to the two bending parts thereof. The guide pillars 4 can reduce the wear of the steel cable 3. The two guide pillars 4 are fixedly connected to the guide rail 101 and the hot pressing mold 201 respectively.

[0031] In this embodiment, the bending part of the steel cable 3 contacts with two cylindrical guide pillars 4, which can effectively reduce the wear of the steel cable 3 and extend the service life of the steel cable 3.
