Description

Technical Field

[0001] This utility model relates to the field of extrusion molding technology, and specifically to an automatic cooling extrusion aid device for extrusion molding. Background Technology

[0002] Extrusion molding is a molding process in which material is extruded into a desired shape through a die. During this process, the material is subjected to strong pressure and forced through the holes or gaps of the die, thus forming a product with a specific cross-sectional shape and length. Extrusion molding is widely used in the processing of materials such as metals, plastics, and rubber, and has advantages such as high production efficiency, precise product dimensions, and high material utilization. In this invention, the extrusion molding process is combined with an automatic cooling extrusion aid device to improve the efficiency of the extrusion molding process and the quality of the product.

[0003] According to patent document CN219405340U, an extrusion device is disclosed, including a plastic extruder main unit. The plastic extruder main unit consists of an extrusion system, a transmission system, a heating and cooling system, a feeding system, and a control system. An L-shaped mounting plate is fixed to the side of the plastic extruder main unit, and an extrusion die for extruding plastic strips is embedded on the surface of the L-shaped mounting plate. A bridging mechanism is provided on the side of the L-shaped mounting plate. In actual use, after the plastic extruder main unit extrudes the plastic strip, the formed plastic strip slides forward via a sliding bar. When the end of the plastic strip corresponds to a proximity switch, the proximity switch automatically controls the motor to start, driving the lead screw to rotate. The rotation of the lead screw drives the sliding bar to move, thereby achieving the purpose of bridging and conveying the end of the plastic strip to the cooling water tank. This avoids the need for manual bridging using auxiliary tools, providing convenience for operators and preventing safety hazards.

A pipe 114 is fixedly connected to the left side of the cold air conveying block 115, and the end of the pipe 114 away from the cold air conveying block 115 is fixedly connected to the cold air tank. On one side of 111, a second clamping plate connecting plate 1120 is fixedly connected to the right side of the top plate 11.

[0025] When metal needs to be extruded, the worker uses a conveying device to transport the heated metal to the inside of clamping plate 119 and second clamping plate 1121. Then, the hydraulic push rod 17 is activated. The hydraulic push rod 17 pushes the bottom of the V-shaped rotating rod 19 to move through the push block 18. The top of the V-shaped rotating rod 19 moves to the right, thereby driving the push-pull plate 118 to move to the right. The two columnar slide rods 117 slide to the right on the inner wall of the guide block 13. At the same time, the rack plate 1126 drives the gear 113 to rotate counterclockwise. The gear 113 drives the rack rod 1123 to move to the left. The rack rod 1123 slides to the left on the inner wall of the slide plate 112 and concave bottom block 116. When the two columnar slide rods 117 move to the right, they drive the clamping plate 119 to move together. The metal moves to the right, at which point the clamping plate 119 and the second clamping plate 1121 squeeze the metal. The rack rod 1123 moves to the left, causing the second cold air conveying block 1124 to move closer to the squeezed metal. The second cold air conveying block 1124 extracts cold air from the cold air tank 111 through the second pipe 1125 and delivers it to the parts that need cooling, thereby achieving rapid cooling of the metal during the extrusion molding process. During this process, the cold air in the cold air tank 111 is continuously extracted and delivered to various parts that need cooling through pipes, ensuring that the metal can be cooled down quickly after extrusion molding, maintaining the stability of its shape and size. The entire device has a simple structure and is easy to operate, which can greatly improve the efficiency and quality of metal extrusion molding.

[0026] Please see Figure 4-5 The cutting mechanism 2 includes a cutting mechanism connecting plate 21. Two inverted U-shaped support rods 22 are fixedly connected to the top right side of the cutting mechanism connecting plate 21. A U-shaped connecting plate 23 is fixedly connected to the top of the two inverted U-shaped support rods 22. U-shaped connecting plate grooves 25 are provided on both the left and right sides of the U-shaped connecting plate 23. A second hydraulic push rod 24 is fixedly connected to the inner wall of the bottom center of the U-shaped connecting plate 23. Two bidirectional hinge rods 29 are rotatably connected to the top of the inner walls of the two U-shaped connecting plate grooves 25. A first rotating rod 28 is rotatably connected to the outer side of each of the two bidirectional hinge rods 29. The inner sides of the two bidirectional hinge rods 29 are rotatably connected to rotating rods 210, and the bottom of the two rotating rods 210 are rotatably connected to cutting plates 211. The outer wall of the cutting plate 211 is slidably connected to the inner side of the U-shaped connecting plate 23. The top of the second hydraulic push rod 24 is fixedly connected to a bottom support plate 26. The left and right sides of the bottom support plate 26 are fixedly connected to bottom support plate sliders 27. The outer walls of the two bottom support plate sliders 27 are rotatably connected to the inner walls of the two U-shaped connecting plate grooves 25. The outer sides of the two bottom support plate sliders 27 are rotatably connected to the bottom of the outer walls of the two first rotating rods 28.

[0027] When it is necessary to cut the extruded metal, the second hydraulic push rod 24 is activated. The second hydraulic push rod 24 drives the bottom support plate 26 to move upward to support the bottom of the metal. The bottom support plate 26 drives the bottom support plate slider 27 to slide on the inner wall of the U-shaped connecting plate groove 25. The bottom support plate slider 27 drives the first rotating rod 28 to rotate. The first rotating rod 28 drives the bidirectional hinge rod 29 to rotate. The bidirectional hinge rod 29 drives the rotating rod 210 to move. The rotating rod 210 drives the cutting plate 211 to slide on the inner wall of the U-shaped connecting plate 23, thereby realizing the downward movement of the cutting plate 211 to cut the metal. This allows the cutting plate 211 to cut metals of different thicknesses, improving the practicality of the device.

[0028] Working principle: When metal needs to be extruded, the operator conveys the heated metal to the inner side of clamping plate 119 and second clamping plate 1121 via a conveying device. Then, the hydraulic push rod 17 is activated. The hydraulic push rod 17 pushes the bottom of the V-shaped rotating rod 19 to move through the push block 18. The top of the V-shaped rotating rod 19 moves to the right, thereby driving the push-pull plate 118 to move to the right. The two columnar slide rods 117 slide to the right on the inner wall of the guide block 13. At the same time, the rack plate 1126 drives the gear 113 to rotate counterclockwise. The gear 113 drives the rack rod 1123 to move to the left. The rack rod 1123 moves between the slide plate 112 and the concave bottom block 116. The inner wall slides to the left, and when the two columnar slide rods 117 move to the right, they drive the clamping plate 119 to move to the right as well. At this time, the clamping plate 119 and the second clamping plate 1121 squeeze the metal. The rack rod 1123 moves to the left. When it moves to the left, it causes the second cold air conveying block 1124 to move closer to the squeezed metal. The second cold air conveying block 1124 extracts cold air from the cold air tank 111 through the second pipe 1125 and delivers it to the parts that need to be cooled, thereby achieving rapid cooling of the metal during the extrusion molding process. During this process, the cold air in the cold air tank 111 is continuously extracted and delivered to various parts that need to be cooled through the pipe.

[0029] When it is necessary to cut the extruded metal, the second hydraulic push rod 24 is activated. The second hydraulic push rod 24 drives the bottom support plate 26 to move upward to support the bottom of the metal. The bottom support plate 26 drives the bottom support plate slider 27 to slide on the inner wall of the U-shaped connecting plate groove 25. The bottom support plate slider 27 drives the first rotating rod 28 to rotate. The first rotating rod 28 drives the bidirectional hinge rod 29 to rotate. The bidirectional hinge rod 29 drives the rotating rod 210 to move. The rotating rod 210 drives the cutting plate 211 to slide on the inner wall of the U-shaped connecting plate 23, thereby realizing the downward movement of the cutting plate 211 to cut the metal.
