Description

An extrusion die with a cooling structure Technical Field

[0001] This utility model relates to the field of extrusion die technology, specifically to an extrusion die with a cooling structure. Background Technology

[0002] Extrusion dies are a type of forming die, but they achieve material discharge through the extrusion process. They are widely used in aluminum profiles and also in plastic parts. During extrusion processing, a significant amount of heat is often generated, necessitating an extrusion die with a cooling structure.

[0003] According to a pipe extrusion die with a cooling structure disclosed in the above application (Announcement No.: CN215550737U), the driving equipment in the above application performs power extrusion on the metal extrusion strip, so that the die-casting structure extrudes the raw material in the processing tank, and connects the connecting pipes at both ends to the external water pipe, so that the cold water flows and circulates in the water pipe. While flowing, the formed pipe in the upper processing tank can be cooled and shaped, which accelerates the cooling speed of the pipe, improves the production efficiency of the device, and thus improves the practicality of the device.

[0004] However, in actual use, the water in the pipes can only move within the pipes. After long-term use, the water in the pipes is easily heated completely, causing the water to lose its cooling effect and thus reducing the effectiveness of the extrusion die. In view of this, we propose an extrusion die with a cooling structure. Summary of the Invention

[0005] The purpose of this invention is to provide an extrusion die with a cooling structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion mold with a cooling structure, comprising a base, a vertical plate fixedly connected to the lower end of the base, a mold shell fixedly connected to the upper outer wall of the base, an inner mold shell fixedly connected to the inside of the mold shell, a cover plate rotatably connected to the outer wall of the base, a latch rotatably connected to the outer wall of the base, a feed inlet penetrating and fixedly connected to the outer wall of the mold shell, and a cooling assembly disposed inside the base, the cooling assembly comprising:

[0007] A cooling pipe is sleeved on the arc-shaped outer surface of the mold shell. The end of the cooling pipe passes through and is fixedly connected to a water storage tank. A motor is fixedly connected to the lower outer wall of the base. A rotating rod is fixedly connected to the output end of the motor. The rotating rod passes through the outer wall of the water storage tank and is rotatably connected to the water storage tank.

[0008] A push plate is fixedly connected to the arc-shaped outer wall of a rotating rod. A reservoir shell is fixedly connected to the arc-shaped outer wall of the rotating rod. A leak shell is slidably connected to the inner wall of the reservoir shell. A spring is fixedly connected to the outer wall of the leak shell.

[0009] Preferably, the base is internally equipped with a heat dissipation assembly, which includes a rotating pulley fixedly connected to the outer wall of the rotating rod. A transmission belt is driven to the arc-shaped outer wall of the rotating pulley, and a driven pulley is driven to the end of the transmission belt away from the rotating pulley. A transmission rod is passed through and fixedly connected to the axis of the driven pulley, and a fan blade is fixedly connected to the arc-shaped outer wall of the transmission rod. A guide plate is fixedly connected to the outer wall of the base above the water tank. A guide groove is formed on the outer wall of the guide plate. When the motor drives the rotating rod to rotate, the rotating rod drives the rotating pulley to rotate, which in turn drives the driven pulley to rotate via the transmission belt, causing the rotating rod to rotate. This causes the fan blade to rotate, allowing the fan blade to cool the water in the water tank. At the same time, the water vapor emitted during cooling is blown onto the guide plate, and the guide groove on the guide plate causes the water droplets condensed from the water vapor to fall to the ground.

[0010] Preferably, the transmission rod is rotatably connected to the lower outer wall of the base, the water storage tank is fixedly connected to the lower outer wall of the base, and the length of the fan blade is the same as the length of the water storage tank, so that the fan blade can completely cool the water in the water storage tank.

[0011] Preferably, the size of the cover plate is the same as the size of the opening of the mold shell. A torsion spring is provided at the connection between the latch and the outer wall of the base. A rubber cylinder is provided at the end of the latch away from the torsion spring. The rubber cylinder contacts the cover plate. Rotating the latch opens the latch. When the cover plate covers the opening of the mold shell, releasing the latch allows the latch to press the cover plate tightly through the torsion spring, so that the cover plate can seal the mold shell.

[0012] Preferably, the end of the leaking shell away from the rotating rod is provided with a mesh opening, the outer wall of the leaking shell is provided with a limiting block, the inner wall of the storage shell is provided with a limiting groove, the limiting block is slidably connected to the inner wall of the limiting groove, the spring is fixedly connected to the limiting block, the other end of the spring is fixedly connected to the inner wall of the limiting groove, and the storage shell is provided with coolant. When the rotating rod rotates to a certain speed, the leaking shell moves inside the storage shell by inertia, causing the mesh opening to leave the storage shell, thereby allowing the coolant to leak out of the storage shell.

[0013] Preferably, the feed inlet is connected through and fixedly connected to the outer wall of the mold shell between the mold shell and the mold inner shell, so that the raw material enters between the mold shell and the mold inner shell through the feed inlet, thereby allowing the raw material to be stably formed into a workpiece through the mold. A funnel is provided at the upper end of the feed inlet, so that the raw material can enter the mold shell and the mold inner shell more easily.

[0014] Compared with the prior art, the present invention provides an extrusion die with a cooling structure, which has the following beneficial effects:

[0015] 1. The extrusion die with a cooling structure is cooled by cooling water through cooling pipes. The motor drives the rotating rod to rotate, which in turn rotates the pusher plate on the rotating rod. This pusher plate can then cool the outer shell of the die with cooling water from the storage tank through the cooling pipes. When the cooling water is too hot, the motor increases the speed of the rotating rod. At this time, the drain shell moves inside the storage tank due to inertia, causing the mesh opening to leave the storage tank and thus allowing the coolant to leak out of the storage tank and cool down.

[0016] 2. The extrusion die with a cooling structure has a rotating rod that drives a self-rotating pulley to rotate. This self-rotating pulley, through a transmission belt, drives a driven pulley to rotate, causing the rotating rod to rotate. This, in turn, drives the fan blades to rotate, allowing the fan blades to cool the water in the storage tank. Simultaneously, the water vapor emitted during cooling is blown onto the air guide plate. The guide grooves on the air guide plate cause the water vapor to condense and drip onto the ground, preventing the condensate from dripping into the storage tank and causing it to rust easily.

[0024] As shown in Figures 1-6, this utility model provides a technical solution: an extrusion mold with a cooling structure, including a base 1, a vertical plate 2 fixedly connected to the lower end of the base 1, a mold shell 3 fixedly connected to the upper outer wall of the base 1, a mold inner shell 4 fixedly connected inside the mold shell 3, a cover plate 5 rotatably connected to the outer wall of the base 1, a latch 6 rotatably connected to the outer wall of the base 1, a feed inlet 7 penetrating and fixedly connected to the outer wall of the mold shell 3, and a cooling assembly 8 provided inside the base 1, the cooling assembly 8 including a cooling pipe 81, a water tank 82, a motor 83, a rotating rod 84, a water pusher 85, a storage shell 86, a drain shell 87, and a spring 88.

[0025] In one embodiment of this utility model, a cooling pipe 81 is sleeved on the arc-shaped outer surface of the mold shell 3. The end of the cooling pipe 81 passes through and is fixedly connected to a water storage tank 82. A motor 83 is fixedly connected to the lower outer wall of the base 1. A rotating rod 84 is fixedly connected to the output end of the motor 83. The rotating rod 84 passes through the outer wall of the water storage tank 82 and is rotatably connected to the water storage tank 82.

[0026] In one embodiment of this utility model, the push plate 85 is fixedly connected to the arc-shaped outer wall of the rotating rod 84, the arc-shaped outer wall of the rotating rod 84 is fixedly connected to the storage shell 86, the inner wall of the storage shell 86 is slidably connected to the leak shell 87, and the outer wall of the leak shell 87 is fixedly connected to the spring 88.

[0027] Additionally, a heat dissipation assembly 9 is installed inside the base 1. The heat dissipation assembly 9 includes a rotating pulley 91, which is fixedly connected to the outer wall of the rotating rod 84. A transmission belt 92 is drivenly connected to the arc-shaped outer wall of the rotating pulley 91. A driven pulley 93 is drivenly connected to the end of the transmission belt 92 away from the rotating pulley 91. A transmission rod 94 is passed through and fixedly connected to the axis of the driven pulley 93. A fan blade 95 is fixedly connected to the arc-shaped outer wall of the transmission rod 94. An air guide plate 96 is fixedly connected to the outer wall of the base 1 above the water storage tank 82. The outer surface of the air guide plate 96... The wall is provided with a guide groove 97. When the motor 83 drives the rotating rod 84 to rotate, the rotating rod 84 drives the self-rotating pulley 91 to rotate, which in turn drives the driven pulley 93 to rotate through the transmission belt 92, causing the rotating rod 84 to rotate. This causes the rotating rod 84 to drive the fan blades 95 to rotate, so that the fan blades 95 can cool the water in the water storage tank 82. At the same time, the water vapor emitted during cooling can be blown onto the air guide plate 96. The guide groove 97 on the air guide plate 96 causes the water vapor to condense and drip onto the ground, making it less likely for the condensate to drip into the water storage tank 82, which would otherwise cause the water storage tank 82 to rust easily.

[0028] In this embodiment of the utility model, the transmission rod 94 is rotatably connected to the lower outer wall of the base 1, the water storage tank 82 is fixedly connected to the lower outer wall of the base 1, and the length of the fan blade 95 is the same as the length of the water storage tank 82, so that the fan blade 95 can completely cool the water in the water storage tank 82, making the cooling water less likely to be heated.

[0029] In this embodiment of the utility model, the size of the cover plate 5 is the same as the size of the opening of the mold shell 3. A torsion spring is provided at the connection between the latch 6 and the outer wall of the base 1. A rubber cylinder is provided at the end of the latch 6 away from the torsion spring. The rubber cylinder contacts the cover plate 5. Rotating the latch 6 opens the latch 6. When the cover plate 5 covers the opening of the mold shell 3, the latch 6 is released so that the latch 6 presses the cover plate 5 through the torsion spring, so that the cover plate 5 can seal the mold shell 3, thereby making it difficult for the raw material in the extrusion mold to leak out.

[0030] In an embodiment of this utility model, a mesh opening is provided at the end of the leaking shell 87 away from the rotating rod 84, a limiting block is provided on the outer wall of the leaking shell 87, a limiting groove is provided on the inner wall of the storage shell 86, the limiting block is slidably connected to the inner wall of the limiting groove, the spring 88 is fixedly connected to the limiting block, and the other end of the spring 88 is fixedly connected to the inner wall of the limiting groove. Coolant is provided in the storage shell 86. When the rotating rod 84 rotates to a certain speed, the leaking shell 87 moves in the storage shell 86 by inertia, causing the mesh opening to leave the storage shell 86, thereby causing the coolant to leak out of the storage shell 86 and preventing the coolant from being heated.

[0031] In an embodiment of this utility model, the feed port 7 penetrates and is fixedly connected to the outer wall of the mold shell 3 between the mold shell 3 and the mold inner shell 4, so that the raw material enters between the mold shell 3 and the mold inner shell 4 through the feed port 7, thereby allowing the raw material to be stably formed into a workpiece through the mold. A funnel is provided at the upper end of the feed port 7, so that the raw material can enter the mold shell 3 and the mold inner shell 4 more easily, making it easier for the raw material to be formed into a workpiece.

[0032] In this invention, during use, the locking buckle 6 is opened by rotating it. When the cover plate 5 covers the opening of the mold shell 3, the locking buckle 6 is released, allowing the locking buckle 6 to press the cover plate 5 tightly through the torsion spring. This seals the mold shell 3, preventing the raw material in the extrusion mold from leaking out. The raw material is then fed into the space between the mold shell 3 and the inner mold shell 4 through the feed inlet 7, allowing the material to be formed into a workpiece. At this time, the motor 83 drives the rotating rod 84 to rotate, causing the pusher plate 85 on the rotating rod 84 to rotate. This allows the pusher plate 85 to cool the mold shell 3 with cooling water from the water tank 82 through the cooling pipe 81. When the cooling water becomes overheated, the motor 83 increases the rotation speed of the rotating rod 84, preventing leakage. The shell 87 moves within the storage shell 86 by inertia, causing the mesh opening to leave the storage shell 86, thus allowing the coolant to leak out of the storage shell 86 and cool down. When the motor 83 drives the rotating rod 84 to rotate, the rotating rod 84 drives the self-rotating pulley 91 to rotate, which in turn drives the driven pulley 93 to rotate via the transmission belt 92, causing the rotating rod 84 to rotate. This causes the rotating rod 84 to drive the fan blades 95 to rotate, enabling the fan blades 95 to cool the water in the water storage tank 82. At the same time, the water vapor emitted during cooling is blown onto the air guide plate 96. The guide grooves 97 on the air guide plate 96 cause the water vapor to condense and drip onto the ground, preventing the condensate from dripping into the water storage tank 82 and causing the water storage tank 82 to rust easily.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
