DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A die casting machine external machine protection device, such as Figure 1-Figure 4As shown, it includes a sliding door 1 and a machine tool 3. The inner wall of the sliding door 1 is fixedly connected with a selection mechanism 2. The selection mechanism 2 includes a mounting plate 201. Two mounting plates 201 are provided. An upper soft iron 202 is fixedly connected between the two mounting plates 201. A lower soft iron 203 is provided below the upper soft iron 202. A magnet 206 is provided between the upper soft iron 202 and the lower soft iron 203. The magnet 206 is rotatably connected to the two mounting plates 201. A pull tab 207 is fixedly connected to one end of the magnet 206. A handle 208 is fixedly connected to one end of the pull tab 207. The operator only needs to pull By turning the handle 208 to rotate the magnet 206, the direction of the magnetic field can be changed, thereby controlling the magnetization state of the upper soft iron 202 and the lower soft iron 203. This not only simplifies the operation process and improves work efficiency, but also effectively reduces the workload of workers. At the same time, the device uses the magnetic principle for transmission, avoiding the mechanical wear problem that is prone to occur in traditional mechanical connection methods. The magnetic force generated by the upper soft iron 202 and the lower soft iron 203 after being magnetized by the magnet 206 can smoothly and reliably drive the opening and closing of the sliding door 1, thereby extending the service life of the device and reducing maintenance costs.

[0038] See also Figure 1 , Figure 2 and Figure 3 A fixed mold 4 is fixedly connected to one side of the top of the machine tool 3, and mounting grooves 5 are provided on the front and rear sides of the fixed mold 4. A trigger piece 6 is arranged inside the mounting groove 5. By fixing the fixed mold 4 on one side of the top of the machine tool 3, and opening mounting grooves 5 on the front and rear sides of the fixed mold 4, and arranging the trigger piece 6 inside, this design enhances the safety of the die-casting operation. Only when the sliding doors 1 on both sides press the trigger piece 6 at the same time, can the safety state of the die-casting machine be confirmed, and then the subsequent operation can be started, which effectively prevents the occurrence of misoperation or accidents and ensures the safety of operators and equipment.

[0039] See also Figure 1 , Figure 2 and Figure 3 A sliding die 7 is arranged on the right side of the fixed die 4, and a movable soft iron 8 is fixedly connected on both sides of the sliding die 7. The sliding die 7 arranged on the right side of the fixed die 4 is closely integrated with the operation process of the die-casting machine, making the die-casting operation smoother and more efficient. The sliding die 7 can move during the die-casting process and cooperate with the fixed die 4 to complete the die-casting operation. At the same time, the movable soft iron 8 fixedly connected on both sides of the sliding die 7 interacts with the magnet 206 in the selection mechanism 2 to form a magnetic transmission system. When the magnet 206 rotates to the up and down directions, the strong magnetic field generated can attract the movable soft iron 8, thereby driving the movement of the sliding die 7, which not only realizes the automatic control of the sliding die 7, but also avoids the wear problem in the traditional mechanical connection, and improves the reliability and service life of the device.

[0040] See also Figure 1 , Figure 2 and Figure 3 , a lower arc groove 204 is provided at the bottom of the upper soft iron 202, and an upper arc groove 205 is provided at the top of the lower soft iron 203. The lower arc groove 204 provided at the bottom of the upper soft iron 202 is combined with the upper arc groove 205 provided at the top of the lower soft iron 203, providing a smoother path for the rotation of the magnet 206, so that the magnet 206 can transition more smoothly during rotation, reducing friction and resistance. At the same time, the existence of the lower arc groove 204 and the upper arc groove 205 also helps to optimize the magnetic field distribution. When the magnet 206 rotates to a specific position, its N pole or S pole can more accurately correspond to the upper soft iron 202 and the lower soft iron 203, making the magnetic field direction clearer and the magnetic force stronger, thereby enhancing the magnetic transmission effect between the sliding door 1 and the sliding mold 7, and improving the response speed and accuracy of the device.

[0041] See also Figure 1 , Figure 2 and Figure 3 , both ends of the magnet 206 are provided with arc-shaped surfaces 9, which are matched with the upper arc groove 205 and the lower arc groove 204. The arc-shaped surfaces 9 provided at both ends of the magnet 206 are matched with the upper arc groove 205 and the lower arc groove 204, so that the magnet 206 can rotate more smoothly, reduce the friction between the magnet 206 and the upper soft iron 202 and the lower soft iron 203, reduce wear, and thus improve the service life of the selection mechanism 2. At the same time, the design of the arc-shaped surface 9 also helps to optimize the magnetic field distribution. When the arc-shaped surface 9 of the magnet 206 is closely matched with the upper arc groove 205 and the lower arc groove 204, it can ensure that the magnetic field acts more concentratedly on the upper soft iron 202 and the lower soft iron 203, thereby improving the magnetization efficiency.

[0042] See also Figure 1 , Figure 2 and Figure 3 The sliding door 1 is made of ductile iron and is provided with a slit 10, which is matched with the pull tab 207. The sliding door 1 is made of ductile iron, which has high strength and wear resistance and can withstand the impact and vibration generated during the operation of the die-casting machine, thereby ensuring the stability and durability of the sliding door 1. At the same time, the existence of the slit 10 provides sufficient space for the pull tab 207 to move, making the pulling process smoother and reducing the difficulty of operation and the force required.

[0043] See also Figure 1 , Figure 2 and Figure 3The sliding door 1 and the machine tool 3 are slidably connected via the polished rod 11, and the surface of the polished rod 11 is coated with a wear-resistant coating. The sliding door 1 and the machine tool 3 are slidably connected via the polished rod 11, ensuring that the sliding door 1 can move steadily and smoothly along the polished rod 11. At the same time, the surface of the polished rod 11 is coated with a wear-resistant coating, which enhances the wear resistance of the polished rod 11, extends the service life of the polished rod 11, and also reduces the maintenance and replacement costs caused by wear.

[0044] The implementation principle of the utility model is as follows: first, when the selection mechanism needs to be operated, the operator rotates the magnet 206 by pulling the handle 208. Since the magnet 206 is rotatably connected to the mounting plate 201, when the handle 208 is pulled, the magnet 206 rotates between the upper soft iron 202 and the lower soft iron 203. When the two poles of the magnet are in the up-down direction, that is, when the N or S pole of the magnet is facing the upper soft iron 202 and the lower soft iron 203, the upper soft iron 202 and the lower soft iron 203 are magnetized. There is a strong magnetism in this direction, which can be used to generate a magnetic force with the moving soft iron 8, so that when the sliding mold 7 slides, it can drive the sliding door 1 to slide, thereby realizing the automatic opening and closing of the sliding door 1.

[0045] Only when the trigger piece 6 inside the mounting groove 5 on the fixed die 4 is pressed by the sliding doors 1 on both sides at the same time, can the die-casting machine be confirmed to be safe and further subsequent operations can be started.

[0046] Embodiment 2:

[0047] See also Figure 4 A top protective plate 12 is fixedly connected to the top of the fixed mold 4, and a fan hole 13 is opened on the top protective plate 12. The top protective plate 12 can effectively prevent splashes that may be generated during the die-casting process from jumping out and causing harm to operators and equipment, thereby providing a safer working environment. At the same time, the fan hole 13 opened on the top protective plate 12 ensures a good ventilation effect, allowing air to circulate, thereby maintaining a good working condition.

[0048] See also Figure 4 The top of the top protective plate 12 is fixedly connected with a cross bar 14, and the top of the cross bar 14 is fixedly connected with a motor 15. The cross bar 14 fixedly connected to the top of the top protective plate 12 provides a stable support for the motor 15. The introduction of the cross bar 14 enhances the structural stability of the entire device, ensuring that the motor 15 will not shake or shift during operation, thereby ensuring the working efficiency and safety of the motor 15. At the same time, the fixed position of the motor 15 is located at the top of the cross bar 14, so that the motor 15 can be away from the die-casting operation area, reducing the possibility of being affected by adverse factors such as high temperature and splashes.

[0049] See also Figure 4The output end of the motor 15 is fixedly connected to a fan 16, and the fan 16 and the fan hole 13 are arranged in a coaxial structure. The fan 16 fixedly connected to the output end of the motor 15 can be directly driven to rotate by the motor 15 to generate a strong airflow, so that the fan 16 can efficiently discharge the heat and exhaust gas generated during the operation of the die-casting machine, thereby maintaining the normal operating temperature of the die-casting machine and its external protective device, and avoiding the performance degradation or damage of the equipment due to overheating. At the same time, the fan 16 and the fan hole 13 are arranged in a coaxial structure, ensuring the smooth discharge of the airflow. The coaxial design enables the airflow generated by the fan 16 to directly pass through the fan hole 13, reducing the resistance and turbulence of the airflow and improving the heat dissipation efficiency.

[0050] The implementation principle of the utility model is as follows: first, when the die-casting machine is running, the motor 15 is started to drive the fan 16 to rotate, so as to absorb the waste gas generated during the die-casting and reduce the amount of pollutants in the air.
