[0016] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0017] Depend on Figures 1 to 5 It can be seen that a plaster cutting machine includes a base 1, a vertical plate 2 is used on the side of the base 1, a fixed plate 3 is vertically slidably arranged on the vertical plate 2, an upper mold 4 is detachably fixed on the fixed plate 3, a lower mold 5 is detachably fixed on the base 1, a cam 6 is rotatably arranged on the vertical plate 2, a connecting rod 7 cooperating with the cam 6 is vertically slidably arranged on the vertical plate 2, the lower end of the connecting rod 7 passes through the fixed plate 3 and is provided with a plug 8, and a first spring 9 located above the fixed plate 3 is sleeved on the connecting rod 7.

[0018] When the utility model is used in a specific way,

[0019] Install appropriate upper mold 4 and lower mold 5 on the fixed plate 3 and the base 1, then place the paste paper film on the lower mold 5, start the equipment, the cam 6 rotates, driving the connecting rod 7 to push the fixed plate 3 downward, the upper mold 4 moves downward and completes the cutting of the paste paper film with the lower mold 5. When the upper mold 4 contacts the lower mold 5, the first spring 9 begins to compress to avoid rigid impact between the upper mold 4 and the lower mold 5, and avoid damage to the upper mold 4 and the lower mold 5.

[0020] When the cam 6 rotates and drives the connecting rod 7 to move upward, the plug 8 drives the fixing plate 3 to move upward synchronously, so that the upper mold 4 is away from the lower mold 5.

[0021] A fixing groove 10 is provided on the base 1 and the fixing plate 3. The fixing groove 10 is T-shaped and has inconsistent widths on both sides. A clamping block 11 corresponding to the fixing groove 10 is provided on the upper mold 4 and the lower mold 5. The widths on both sides of the fixing groove 10 are inconsistent, so that the upper mold 4 and the lower mold 5 have an anti-reverse effect, which can prevent the mold from being installed upside down, thereby ensuring smooth mold closing.

[0022] A baffle rod 12 is provided in the fixing groove 10, and a second spring 13 is sleeved on the baffle rod 12. The second spring 13 pushes the baffle rod 12 inwardly. A pull ring 14 is provided at the outer end of the baffle rod 12. The baffle rod 12 is used to limit the upper mold 4 and the lower mold 5 so that they are fixed in the cutting equipment and will not fall out during work, thereby ensuring smooth cutting work.

[0023] A motor 15 is fixed above the vertical plate 2, and the motor 15 drives the cam 6 to rotate. A ring groove 16 is provided on the edge of the cam 6, and the upper end of the connecting rod 7 is inserted into the ring groove 16. A convex ring 17 is provided on the connecting rod 7, and the first spring 9 is located between the convex ring 17 and the fixed plate 3.

[0024] The motor 15 drives the cam 6 to rotate, and the upper end of the connecting rod 7 is inserted into the annular groove 16 of the cam 6. The cam 6 is eccentrically arranged. When the cam 6 rotates, the connecting rod 7 is vertically lifted and lowered, thereby driving the fixed plate 3 to lift and lower, and realizing the movement of the upper mold 4.

[0025] The first spring 9 is arranged between the convex ring 17 and the fixed plate 3. When the connecting rod 7 moves downward, the first spring 9 pushes the fixed plate 3 to move downward, and starts to compress after the upper mold 4 and the lower mold 5 are closed, avoiding rigid impact between the upper mold 4 and the lower mold 5, thereby protecting the equipment.

[0026] A matching vertical groove is provided between the fixing plate 3 and the vertical plate 2 to improve the stability of the fixing plate 3 .

[0027] A connecting plate that slides vertically on the vertical plate 2 is fixed on the connecting rod 7 to ensure the vertical state of the connecting rod 7, so as to accurately lift and lower the fixed plate 3.

[0028] Compared with the prior art, the utility model has the following beneficial effects: a spring is added between the driving device and the upper die, the rigid connection is changed into a flexible connection, the damage caused by the rigid impact is avoided, the equipment is protected, and the service life of the equipment is extended.
