A cutting device 5 is provided on the surface of the first mold 1, and the cutting device 5 includes two first connecting frames 51 and two second connecting frames 52. The two first connecting frames 51 are located at one end of the first mold 1 away from the second mold 2 and are fixedly connected. The two second connecting frames 52 are located on the side of the first mold 1 and are fixedly connected. The first connecting frames 51 and the second connecting frames 52 are connected by a sliding rod 53. The surface of the sliding rod 53 is slidably connected to a moving head 55, and one end of the moving head 55 is fixedly connected to a cutting knife 54; the surface of the sliding rod 53 is sleeved with a spring 56, and the two ends of the spring 56 are respectively fixedly connected to the lower surface of the moving head 55 and the upper surface of the second connecting frame 52, and one end of the moving head 55 is fixedly connected to a rack 57.

[0023] The provision of a rack 57 allows for movement of the moving head 55, reducing the likelihood that the moving head 55 will be unable to move downward during use, making it difficult for the cutting blade 54 to cut the material. A connecting base 510 is fixedly connected to the side of the first mold 1. The end of the connecting base 510, which is away from the first mold 1, is fixedly connected to a motor 59. The provision of the connecting base 510 facilitates the positioning of the motor 59. A gear 58 is fixedly connected to the output end of the motor 59, which meshes with the rack 57. The provision of the gear 58 facilitates the movement of the rack 57.

[0024] In this embodiment, a cooling device 6 is provided inside the first mold 1. The cooling device 6 includes a connecting hole 61 and a heat dissipation pipe 62. The connecting hole 61 is provided inside the first mold 1, and the heat dissipation pipe 62 is disposed inside the connecting hole 61. A connecting sleeve 64 is fixedly connected to one end of the first mold 1 away from the connecting seat 510. Connecting pipes 63 are fixedly connected to both ends of the heat dissipation pipe 62, and the connecting pipes 63 are disposed inside the connecting sleeve 64. The provision of the connecting pipe 63 allows the conversion tank 65 and the heat dissipation pipe 62 to be connected, thereby reducing the difficulty of the cooling liquid inside the conversion tank 65 communicating with the interior of the heat dissipation pipe 62 when the device is in use.

[0025] One end of the connecting pipe 63 away from the heat dissipation pipe 62 is fixedly connected to the conversion tank 65 , and the lower end of the conversion tank 65 is fixedly connected to the support frame 66 . The support frame 66 is provided to facilitate supporting and limiting the conversion tank 65 .

[0026] The upper end of the conversion tank 65 is fixedly connected to a pump body 68 , and the end of the conversion tank 65 away from the first mold 1 is fixedly connected to a feed head 67 . The pump body 68 is provided to facilitate the circulation of the cooling liquid inside the conversion tank 65 .

[0027] The working principle of the present invention is as follows: the device is installed at the discharge of the extruder, and then the material enters the cavity inside the first mold 1 through the second mold 2, and then is extruded through the internal cavity of the first mold 1. When the device is in use, the user starts the motor 59, and then the motor 59 rotates and drives the gear 58 to rotate. When the gear 58 rotates, it drives the rack 57 to move, and then the rack 57 moves and drives the moving head 55 to move. Then the moving head 55 moves on the surface of the slide bar 53, and when the moving head 55 moves, it drives the cutting knife 54 to move downward, and then the cutting knife 54 moves to cut the material extruded by the first mold 1. When the moving head 55 moves, it drives the spring 56 to displace and deform to generate elastic force. When the cutting knife 54 is on the After the material is cut, the rack 57 disengages from the teeth on the surface of the gear 58, and then the moving head 55 loses its restraint. The spring 56 resets and drives the moving head 55 to move on the surface of the slide bar 53 to move the cutting knife 54 away from the surface of the first mold 1. By setting up the cutting device 5, the material extruded by the first mold 1 is effectively cut, which plays a role in cutting the extruded material. After the equipment extrude the material from one end of the first mold 1, it is generally necessary to manually cut the material. Manual cutting is difficult to accurately control the length of the cut material, resulting in different lengths of the cut material, requiring secondary processing, and wasting money. The cutting device 5 can quickly and evenly cut the extruded material, thereby improving the practicality of the equipment.

[0028] When the equipment is in use, the user starts the pump body 68, and then the pump body 68 runs to drive the cooling liquid inside the conversion tank 65 into the heat dissipation pipe 62 through the connecting pipe 63, and then the heat dissipation pipe 62 absorbs the heat inside the first mold 1. By setting the cooling device 6, the first mold 1 is effectively cooled, and the inside of the first mold 1 is quickly cooled by absorbing heat. When the equipment is in use, when the material is extruded through the inside of the first mold 1, high temperature is generated due to the extrusion, which easily makes it difficult to quickly cool down the extruded material and form it. At the same time, high temperature is generated inside the first mold 1, which easily causes the equipment to extrude irregular-shaped materials and produce defective products. The cooling device 6 can absorb the cooling heat inside the first mold 1, thereby improving the practicality of the equipment.
