[0002] An extruder is a mechanical device used to extrude materials such as metal, plastic, rubber, and food through a die or channel. This device pushes the material from one end of the die through strong pressure, forming it into the desired shape or cross-section at the other end. Extruders are widely used in many industries, including metal processing, plastic processing, and food processing.

[0003] However, in the prior art, the extrusion die pressing device in most extruders only presses one side of the extrusion die, and does not press multiple sides of the extrusion die together, resulting in the extrusion die not being in the center position, affecting the processing accuracy of the extrusion die on the material, and being inconvenient to use. Utility Model Content

[0004] In order to make up for the shortcomings of the existing technology, the extrusion die clamping device in most extruders only clamps one side of the extrusion die, and does not align and clamp multiple sides of the extrusion die together, resulting in the extrusion die not being able to be in the center position, affecting the processing accuracy of the extrusion die on the material, and being inconvenient to use. The utility model proposes a super-wide profile extrusion machine die clamping device.

[0007] Preferably, a positioning rod is fixedly connected to one side of the connecting plate, and a surface of the positioning rod is slidably connected to the inner cavity of the mold base.

[0008] Preferably, the extrusion mechanism includes an outer shell, an inner wall of the outer shell is fixedly connected to an inner lining, a surface of the inner lining is provided with first extrusion holes, and the number of the first extrusion holes is the same as the number of the extrusion rods.

[0009] Preferably, a heating device is fixedly installed in the inner cavity of the shell, and the number of the heating devices is multiple.

[0010] Preferably, second extrusion holes are opened on the surface of the extrusion die, the number of the second extrusion holes is the same as the number of the first extrusion holes, and the inner walls of the second extrusion holes correspond to the inner walls of the first extrusion holes.

The first connecting rod and the second connecting rod are rotatably connected between the pressure block and the connecting plate. The connecting plate is connected to the die base through the push rod. The angle between the first connecting rod and the second connecting rod is guaranteed to be less than ninety degrees. Therefore, when the pressure block is pressed downward, it drives the first connecting rod and the second connecting rod to reduce the angle and push the connecting plate and the push rod, so that the push rods on both sides press the other two sides of the extrusion die, achieving the effect of pressing in a centralized manner, so that the extrusion die is in a central position, and the processing accuracy of the extrusion die on the material is improved. This solves the problem that the extrusion die clamping device in most extruders only presses one side of the extrusion die when pressing the extrusion die, and does not centrally press multiple sides of the extrusion die together, resulting in the extrusion die not being able to be in a central position, affecting the processing accuracy of the extrusion die on the material, and being inconvenient to use.

The hydraulic cylinder 2 can push the push plate 3, and the push plate 3 can drive the extrusion rod 4. The extrusion mold 7 is limited by the mold base 5. The cylinder 802 first pushes the pressure block 803 downward to press one side of the extrusion mold 7. The first connecting rod 805 and the second connecting rod 806 are rotatably connected between the pressure block 803 and the connecting plate 807. The connecting plate 807 is connected to the mold base 5 through the push rod 808. The angle between the first connecting rod 805 and the second connecting rod 806 is guaranteed to be less than ninety degrees. Therefore, the pressure block 803 presses downward while driving the first connecting rod 805 and the second connecting rod 806 to reduce the angle and push the connecting plate 807 and the push rod 808, so that the push rods 808 on both sides press the other two surfaces of the extrusion mold 7, thereby pressing through the clamping mechanism 8, so that the extrusion mold 7 is in the center position, thereby improving the processing accuracy of the extrusion mold 7 on the material.

[0025] Reference Figure 3 A positioning rod 9 is fixedly connected to one side of the connecting plate 807, and the surface of the positioning rod 9 is slidably connected to the inner cavity of the mold base 5. Through the setting of the positioning rod 9, the positioning rod 9 is fixedly connected to the connecting plate 807, so that when the first connecting rod 805 and the second connecting rod 806 drive the connecting plate 807 to move, the connecting plate 807 is limited to the mold base 5 through the positioning rod 9, ensuring the stable lateral displacement of the connecting plate 807 and the push rod 808.

One end of the telescopic rod 11 is fixedly connected to one side of the push plate 3. Through the arrangement of the telescopic rod 11, the sleeve of the telescopic rod 11 plays a major connecting role. The sliding rod of the telescopic rod 11 is fixedly connected to the push plate 3 and slides along the inner cavity of the sleeve. When the hydraulic cylinder 2 pushes the push plate 3 for extrusion, the sliding rod of the telescopic rod 11 is synchronously extended and retracted along the sleeve, thereby increasing the stability of the push plate 3.

[0029] Working principle: The hydraulic cylinder 2 can push the push plate 3, and the push plate 3 can drive the extrusion rod 4. The extrusion mold 7 is limited by the mold base 5. The cylinder 802 first pushes the pressure block 803 downward to press one side of the extrusion mold 7. The first connecting rod 805 and the second connecting rod 806 are rotatably connected between the pressure block 803 and the connecting plate 807. The connecting plate 807 is connected to the mold base 5 through the push rod 808. The angle between the first connecting rod 805 and the second connecting rod 806 is guaranteed to be less than ninety degrees. Therefore, when the pressure block 803 is pressed downward, it drives the first connecting rod 805 and the second connecting rod 806 to reduce the angle and push the connecting plate 807 and the push rod 808, so that the push rods 808 on both sides press the other two surfaces of the extrusion mold 7, thereby pressing through the clamping mechanism 8, so that the extrusion mold 7 is in the center position, thereby improving the processing accuracy of the extrusion mold 7 on the material.
