[0033] The driving mechanism 3 is arranged on the frame 1;
[0034] The cutting mechanism 4 is connected to the output end of the driving mechanism 3, and the cutting mechanism 4 includes a hot melt wire 41, and the hot melt wire 41 is attached to the outer wall of the forming frame 2;
[0035] The cutting mechanism 4 is driven by the driving mechanism 3 to keep reciprocating motion, so that the hot melt wire 41 attached to the outer wall of the forming frame 2 moves.
[0036] Specifically, the forming frame 2 is fixedly installed on the frame 1, and the forming frame 2 is a hollow structure, which can be used to place the foam plate to be cut. In use, the foam plate to be cut is placed in the forming frame 2, and the size of the foam plate is preferably matched with the size of the forming frame 2, so that the foam plate can be simply positioned.
[0037] The driving mechanism 3 is arranged on the frame 1, and the cutting mechanism 4 is connected to the output end of the driving mechanism 3. The cutting mechanism 4 includes a hot melt wire 41. In use, the cutting mechanism 4 is driven by the driving mechanism 3 to keep reciprocating motion on the frame 1, so that the hot melt wire 41 keeps moving along the outer wall of the forming frame 2. The hot melt wire 41 keeps moving and abuts against the foam plate in the forming frame 2. The foam plate is cut by abutting against the hot melt wire 41. Since the hot melt wire 41 is attached to the outer wall of the forming frame 2 during movement, the foam plate can be cut into a plate with the same shape as the side wall of the forming frame 2, which is convenient for subsequent slitting.
[0038] The utility model discloses a driving mechanism 3 drives the cutting mechanism 4 to keep sliding, so that the hot melt wire 41 on the cutting mechanism 4 moves along the forming frame 2. During the movement of the hot melt wire 41, the foam plate connected inside the forming frame 2 abuts, and the foam plate is cut into the shape of the edge of the forming frame 2. The special-shaped foam plate can be preliminarily cut, so that subsequent secondary cutting is facilitated, and the production efficiency of special-shaped foam core material can be improved.
[0039] As an embodiment provided by the utility model, Figure 6As shown, the forming frame 2 includes a fixing strip 21 and a forming strip 22. There are several fixing strips 21 and forming strips 22. The fixing strips 21 and forming strips 22 are connected in sequence to form a frame structure.

The other end of the hot wire 41 is connected to the tension spring 49, and the elasticity of the tension spring 49 always keeps the hot wire 41 tight, ensuring that it can still fit the top of the forming frame 2 after replacing different forming frames 2.
[0047] As further embodiments of the present application, as shown in Figure 5As shown, the driving mechanism 3 comprises a driving motor 31, a screw rod 32, a mounting base 33, a guide rod 34 and a sliding block 35.

One end of the mounting beam 42 is connected to the sliding block 35.
[0048] Working principle:
[0049] Before cutting, the foam plate to be cut is placed in the forming frame 2, and then the switch of the suction pump 51 is started, and the foam plate is adsorbed on the fixed plate 11 by negative pressure;
