[0037] The demolding assembly 2 comprises a bottom plate 21 connected with the bottom surface of the die groove 13, an annular plate 22 arranged on the bottom plate 21 and connected with the side wall of the die groove 13, a fixed plate 23 arranged on the end of the annular plate 22 and connected with the surface of the lower die 12, and a cylinder 24 arranged at the center of the bottom plate 21; the cylinder 24 is sleeved outside the column 15.

[0038] The center of the upper die 11 is provided with a groove 14 matched with the cylinder 24, and the groove 14 is matched with the cylinder 24 to ensure the compression molding of the upper die 11.

[0039] Wherein, since the friction surface sheet is annular structure, the mold groove 13 and the column 15 are concentrically arranged, forming the annular groove body of the friction surface sheet. The bottom plate 21 is a circular ring, the annular plate 22 is a straight plate with a diameter matching the outer diameter of the bottom plate 21, surrounding the side plate which is in close contact with the inner wall of the mold groove 13, and the diameter of the cylinder 24 matches the inner diameter of the annular plate 22; the bottom plate 21, the annular plate 22 and the cylinder 24 are seamlessly connected by integral molding or welding, and the movable mold formed by the bottom plate 22, the annular plate 22 and the cylinder 24 is completely connected with the mold groove 13 and the column 15, which ensures that the friction surface sheet can be smoothly demolded after compression molding.

[0040] It is worth mentioning that the end of the fixed plate 23 away from the annular plate 22 extends to the outer end of the outer wall of the lower mold 12, which has the advantage of facilitating the application of force to the fixed plate 23 to facilitate the lifting of the movable mold formed by the bottom plate 22, the annular plate 22 and the cylinder 24. The number of fixed plates 23 can be one or more. When the number is one, the fixed plate 23 is an annular plate body. When the number is more than one, the fixed plate 23 can be an arc-shaped plate body, which is distributed at fixed intervals on the outer circumferential side of the annular plate 22. The fixed plate 23 is welded or integrally formed with the annular plate 22, and the installation height of the fixed plate 23 on the annular plate 22, i.e. the depth of the mold groove 13, ensures that the fixed plate 23 can be in close contact with the upper surface of the lower mold 12, avoiding the shaking of the movable mold and affecting the compression molding effect.

[0041] In this embodiment, the mold further comprises a reinforcing assembly 3, which comprises a fixed frame 31 connected with the outer side wall of the lower mold 12, a support plate 32 arranged on the fixed frame 31 and used to support the fixed plate 23, a positioning hole 33 arranged on the fixed plate 23, a threaded rod 34 arranged on the support plate 32 and passing through the positioning hole 33, a fastening nut 35 arranged on the threaded rod 34, and an elastic layer 36 arranged on the end of the support plate 32 close to the outer side wall of the lower mold 12. Wherein, the support plate 32 is installed on the outer side wall of the lower mold 12 through the fixed frame 31, and the upper surface of the support plate 32 abuts against the lower end of the fixed plate 23 extending to the outside of the lower mold 12. The surface of the support plate 32 abutting against the outer side wall of the lower mold 12 is preferably an arc surface, and the elastic layer 36 is further arranged on the surface, which is used to increase the friction between the support plate 32 and the lower mold 12 and to reduce the wear between them. The support plate 32 and the fastening nut 35 clamp the upper and lower ends of the fixed plate 23 respectively, ensuring the fixing effect of the fixed plate 23.

[0042] As a preferred of the embodiment, the fixing frame 31 comprises a vertical plate 311 connected with the end of the support plate 32, and a connecting piece 312 arranged on the end of the vertical plate 311 away from the support plate 32 and detachably connected with the outer side wall of the lower mold 12. Further, the connecting piece 312 comprises an arc-shaped plate 312a abutting with the outer side wall of the lower mold 12, an opening 312b arranged on the arc-shaped plate 312a, an inner threaded groove 312c arranged on the outer side wall of the lower mold 12, and a mounting bolt 312d passing through the opening 312b and threadedly connected with the inner threaded groove 312c. Wherein, the vertical plate 311 and the support plate 32, the arc-shaped plate 312a are all welded or integrally formed, so as to ensure the structural strength of the fixing frame 31 and the support plate 32.

[0043] The working principle of the multi-layer pressing mold for clutch facing provided by the embodiment is as follows: the demolding assembly 2 is embedded into the lower mold 12, and the demolding assembly 2 is fixed by the reinforcing assembly 3, then the upper mold 11 is driven to approach the lower mold 12 by the driving assembly (generally a hydraulic device), and is embedded into the demolding assembly 2, the groove 14 is embedded with the cylinder 24, and an annular mold cavity for forming a facing is formed.

[0044] Embodiment 2

[0045] The embodiment is based on the structure optimization of the embodiment 1, as shown in the accompanying drawings Figure 4 The accompanying drawings Figure 6 are as follows:

[0046] The mold further comprises a lifting assembly 4, the lifting assembly 4 comprises a connecting frame 41 arranged on the outer side wall of the upper mold 11, a connecting hole 42 arranged on the connecting frame 41 and used for passing through the threaded rod 34, and a limiting nut 43 arranged on the threaded rod 34.

[0047] Wherein, the connecting frame 41 is fixedly connected or detachably connected with the upper mold 11. The distance between the connecting frame 41 and the lower bottom surface of the upper mold 11 is greater than the depth of the mold groove 13, so as to ensure that the connecting frame 41 does not interfere with the pressing effect of the upper mold 11. The limiting nut 43 is located at the upper end of the connecting frame 41, and the connection between the connecting frame 41 and the threaded rod 34 is completed.

[0048] As a further preferred of the embodiment, the lifting assembly 4 further comprises a strip-shaped groove 44 arranged on the threaded rod 34, and a mark 45 arranged in the strip-shaped groove 44. Wherein, the mark 45 can be a scale or other marks such as graphics, characters and the like which can mark the position of the connecting frame 41 on the threaded rod 34, which is beneficial to accurately mark the descending height of the upper mold 11, and is beneficial to control the thickness of the facing formed by pressing.

[0049] The working principle of the clutch face sheet multilayer pressing die provided by the embodiment is as follows: after the upper die 11 is lowered to a certain height and before the lower die 11 is embedded into the lower die 12, the connecting frame 41 is slid to a certain position on the threaded rod 34, and the limiting nut 43 is screwed to abut against the upper surface of the connecting frame 41, then the lower die 11 is embedded into the lower die 12 and the pressing is completed, after the face sheet is formed, before the upper surface of the connecting frame 41 abuts against the lower surface of the limiting nut 43 again, the connection between the fixing frame 31 and the lower die 12 is released, or the pressing of the fixing plate 23 by the fastening nut 35 is released, the whole demolding assembly 2 is lifted by the lifting assembly 4 to lift the face sheet, so that the demolding assembly 2 is separated from the lower die 12, finally the connection between the connecting frame 41 and the threaded rod 34 is released, and the removal of the demolding assembly 2 is completed.
