Description

[0001] This utility model relates to the field of die head structure technology, and in particular to an adjustable die head for rubber extrusion. Background Technology

[0002] Rubber extrusion dies are the main component of rubber extrusion molding. Installed at the die head of a rubber extruder, they are used to extrude the rubber melt from the extruder screw into a predetermined shape and size. The rubber extrusion die affects the shape, dimensional accuracy, surface quality, and performance of the extruded rubber product. It typically has a specific flow channel structure that allows the rubber melt to pass evenly through the die under pressure, and then forms the final rubber product during subsequent cooling and setting processes to meet the requirements of production processes and product quality.

[0003] Adjustable die heads for rubber extrusion are mold devices that can adjust the shape and size of the die mouth according to different production needs during the rubber extrusion molding process.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Referring to Figures 1, 3, and 4, one embodiment of this utility model provides an adjustable-mouth rubber extrusion die, including a fixed platform 1. Fixed blocks 3 are fixedly connected to the left and right sides of the outer wall of the fixed platform 1. Connecting columns 4 are fixedly connected to the front and rear sides of the outer walls of the two fixed blocks 3. A movable platform 5 is slidably connected to the top of the outer wall of the connecting columns 4. Hydraulic push rods 6 are fixedly connected to the left and right sides of the bottom of the movable platform 5. Movable rods 7 are fixedly connected to the output ends of the two hydraulic push rods 6. The movable rods 7 are slidably connected to the front and rear sides of the bottom of the movable platform 5. Adjusting rods 8 are equidistantly rotatably connected to the bottom of the movable rods 7. Connecting rods 9 are rotatably connected to adjacent sides of the inner walls of the multiple adjusting rods 8. An adjusting column 10 is fixedly connected to the bottom of the inner wall of the fixed platform 7. An upper die head 11 is rotatably connected to the bottom of the outer wall of the adjusting column 10. A mold 14 is fixedly connected to the top of the outer wall of the fixed platform 1. Feed holes 15 are opened on the front and rear sides of the outer wall of the mold 14. A limit frame 12 is fixedly connected at equal intervals in the middle of the inner wall of the mold 14. A lower die head 13 is fixedly connected to the front and rear sides of the outer wall of the limit frame 12. The mold 14 is slidably connected to the middle of the inner wall of the lower die head 13. A cutting mechanism 2 is fixedly connected to the rear side of the outer wall of the fixed platform 1. The cutting mechanism 2 is used to cut off the extrusion die head. A moving frame 16 is fixedly connected to the bottom of the outer wall of the limit frame 12. A fixed frame 17 is slidably connected to the middle of the inner wall of the limit frame 12.

[0032] Specifically, this adjustable-die rubber extrusion head achieves die shape adjustment and extrusion through the cooperation of multiple components. The fixed platform 1 provides basic support, while the fixed block 3 and connecting column 4 form a sliding guide for the moving platform 5, allowing it to slide up and down along the column. The hydraulic push rod 6 pushes the moving rod 7 to slide at the bottom of the moving platform 5, driving the adjusting rod 8 and connecting rod 9 to move. The adjusting column 10 cooperates to adjust the angle and position of the upper die head 11. The feed hole 15 of the die 14 introduces rubber raw material. The limiting frame 12 and lower die head 13 position and support the die 14, which can slide within the lower die head 13. Combined with the adjustment of the upper die head 11, this allows for flexible changes in the die shape to meet the production needs of different rubber products. The fixed platform 1, connected to the cutting mechanism 2, provides a supporting foundation for cutting off the extrusion die. When the extrusion die is finished or needs to be replaced, the cutting mechanism 2 comes into play, precisely cutting off the extrusion die to ensure the normal operation of subsequent production processes. The movable frame 16 at the bottom of the limiting frame 12 can drive the limiting frame 12 to move as a whole and adjust its position; at the same time, the inner wall of the limiting frame 12 is slidably connected to the fixed frame 2 17, so that the fixed frame 2 17 can slide in a specific direction within the limiting frame 12, thereby limiting and fixing the extrusion die head at different positions or sizes, providing a stable cutting object for the cutting mechanism 2, and ensuring the accuracy and stability of the cutting work.

[0033] Referring to Figures 1, 2, and 5, the cutting mechanism 2 includes a fixed frame 201, which is fixedly connected to the rear side of the outer wall of the fixed platform 1. A motor 202 is fixedly connected to the right side of the outer wall of the fixed frame 201. A turntable 203 is fixedly connected to the output end of the motor 202. An adjusting plate 204 is rotatably connected to the top of the outer wall of the turntable 203. An adjusting frame 205 is rotatably connected to the bottom of the outer wall of the turntable 203. An electric push rod 206 is fixedly connected at equal intervals to the top of the outer wall of the adjusting frame 205. A cutter 207 is fixedly connected to the output end of the electric push rod 206. Multiple support plates 18 are fixedly connected to the front and rear sides of the bottom of the fixed platform 1. Fixed holes 19 are equidistantly opened in the middle of the inner wall of the fixed platform 1. Fixed pads 20 are fixedly connected at equal intervals to the top of the outer wall of the fixed frame 201. Wear-resistant pads 21 are fixedly connected to the top of the outer wall of the fixed pads 20.

[0034] Specifically, the cutting mechanism 2 is supported by the fixed frame 201 and installed on the rear side of the fixed platform 1. After the motor 202 is powered on, it drives the turntable 203 to rotate, which, in conjunction with the adjusting plate 204 and the adjusting frame 205, changes the position and angle of the cutter 207. The electric push rod 206 is activated to push the cutter 207 to perform the cutting operation, realizing the automated cutting function. The fixed platform 1, through multiple support plates 18 set on the front and rear sides of the bottom, expands the contact area with the ground, disperses pressure, enhances its own stability, and ensures that the equipment is stable and does not shake during operation. The fixing hole 19 opened in the middle of the inner wall can be used with bolts and other connecting parts to realize the stable installation and positioning of other components on the fixed platform 1. The fixing pad 20 set on the top of the fixed frame 201 plays a role in buffering and shock absorption, reducing the rigid contact between the installed equipment and the fixed frame 201; while the wear-resistant pad 21 on the top of the fixing pad 20, through its high wear resistance, reduces frictional wear during long-term use of the equipment, extends the service life of the fixed frame 201 and the equipment, and enhances the reliability of the equipment after installation.

[0035] Referring to Figures 1, 2 and 3, a connecting rod 22 is fixedly connected to one side of the outer wall of the adjusting plate 204. A limit rod 23 is rotatably connected to the left and right ends of the outer wall of the connecting rod 22. A support frame 24 is fixedly connected to the front side of the outer wall of the fixed platform 1. A support platform 25 is fixedly connected at equal intervals to the top of the outer wall of the support frame 24. A support block 26 is fixedly connected to one side of the outer wall of the fixed platform 1 and the moving platform 5. A telescopic rod 27 is fixedly connected to one side of the outer wall of the support block 26.

[0036] Specifically, the adjusting plate 204 is rotatably connected to the limiting rod 23 via the connecting rod 22, allowing the limiting rod 23 to rotate flexibly and adjust the position or state of related components. The support frame 24 fixedly connected to the fixed platform 1 and the equidistant support platform 25 on the top provide certain support and load-bearing functions for the overall structure. At the same time, the fixed platform 1 and the moving platform 5 are connected by support blocks 26, and telescopic rods 27 are provided between the support blocks 26. The telescopic rods 27 can be extended or retracted as needed, thereby adjusting the distance between the fixed platform 1 and the moving platform 5 or changing their relative positions to adapt to different working requirements.

[0037] Working principle: The fixed platform 1 serves as the basic support, and the fixed blocks 3 on both sides and the connecting column 4 together form the sliding guide structure of the moving platform 5, allowing the moving platform 5 to slide smoothly up and down along the connecting column 4. The hydraulic push rod 6 pushes the moving rod 7 to move at the bottom of the moving platform 5, which in turn drives the adjusting rod 8 and the connecting rod 9 to move in tandem. At the same time, the adjusting column 10 cooperates to enable the upper die head 11 to achieve precise adjustment of angle and position. The feed hole 15 on the die 14 is used to introduce rubber raw materials, while the limiting frame 12 and the lower die head 13 provide positioning and support for the die 14. The die 14 can slide within the lower die head 13. Combined with the adjustment of the upper die head 11, the extrusion die head shape can be flexibly adjusted to meet the production needs of different rubber products.

[0038] The cutting mechanism 2 uses a fixed frame 201 as its support base, with the fixed platform 1 installed at the rear. When the motor 202 is powered on, its output drives the turntable 203 to rotate. As the turntable 203 rotates, it interacts with the adjusting plate 204 and the adjusting frame 205. Driven by the turntable 203, the adjusting plate 204 and the adjusting frame 205 change position and angle, thereby adjusting the spatial position of the cutter 207. When an object needs to be cut, the electric push rod 206 is activated, and its output pushes the cutter 207 forward. With the thrust provided by the motor 202 and the electric push rod 206, the cutter 207 precisely cuts the target object, achieving automated cutting.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
