[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-3 This utility model provides a technical solution: an anti-pinch device for a die-casting machine, including a base 1, a melting mechanism 19, a die-casting mechanism 20, and a protective mechanism 21, all mounted on the base 1. The die-casting mechanism 20 is fixedly mounted on the base 1. The melting mechanism 19 includes a melting furnace 2 and a feeding mechanism 3. The die-casting mechanism 20 includes a die-casting block 4, a die-casting frame 5, and a die-casting table 6. The die-casting block 4 is movably connected to the die-casting frame 5. The die-casting table 6 is fixedly mounted on one side of the die-casting frame 5. A telescopic rod 7 is provided on one side of the die-casting block 4. The telescopic rod 7 is telescopically moved by a cylinder 8. The protective mechanism 21 includes a buffer damping device 9 and a protective baffle 10. The buffer damping device 9 is located between the die-casting block 4 and the die-casting table 6. The protective baffle 10 is fixedly mounted on both sides of the die-casting frame 5.
[0022] Specifically, the buffer damping device 9 includes a spring damper 11 and a rubber buffer pad 12. The spring damper 11 is connected to the die-casting block 4, and the rubber buffer pad 12 is arranged around the spring damper 11 to further enhance the buffering effect. With the above arrangement, the die-casting block 4 can move smoothly when the die-casting machine is working, reducing the damage to the die-casting machine caused by excessive impact force, and also effectively preventing the operator's hand from being pinched.
[0023] Specifically, the smelting furnace 2 is fixedly installed on one side of the base 1, and the feeding mechanism 3 includes a material pump 13, which is fixedly installed on the top outer wall of the smelting furnace 2 by bolts. Through the above arrangement, the feeding mechanism 3 can stably feed the raw materials into the smelting furnace 2 for smelting, ensuring the continuity and stability of the smelting process.
[0024] Specifically, one end of the material pump 13 is connected to a feed pipe 14, one end of which is located inside the smelting furnace 2. The other end of the material pump 13 is connected to a discharge pipe 15. Through the above arrangement, the raw material can smoothly enter the smelting furnace 2 through the feed pipe 14, and after smelting, the molten metal is discharged through the discharge pipe 15, which facilitates the subsequent die casting operation.
[0025] Specifically, the buffer damping device 9 also includes a human infrared sensor 16. The human infrared sensor 16 is used to sense the human body between the die-casting block 4 and the die-casting table 6. With the above settings, when the operator's hand or other body parts accidentally enter between the die-casting block 4 and the die-casting table 6, the human infrared sensor 16 can quickly sense it and trigger an alarm, and at the same time stop the operation of the die-casting machine, thereby effectively avoiding safety accidents such as hand pinching and further improving the safety of the die-casting machine.
[0026] Specifically, an emergency stop button 17 is provided on one side of the die-casting block 4. The emergency stop button 17 is electrically connected to the control system of the die-casting machine. With the above setting, in an emergency, the operator can quickly press the emergency stop button 17 to stop the die-casting machine immediately, thereby preventing the accident from escalating further and ensuring the safety of the operator.
[0027] Specifically, the spring damper 11 is equipped with fixing plates 18 on both the upper and lower sides. This arrangement allows the spring damper 11 to be more securely connected between the die-casting block 4 and the die-casting table 6, enhancing the stability and durability of the buffer damping device 9. At the same time, the design of the fixing plates 18 facilitates the installation and maintenance of the spring damper 11, improving the reliability and service life of the entire die-casting machine's anti-pinch device.
[0028] A specific application example of this embodiment is as follows:
[0029] In operation, the operator first feeds the raw material into the melting furnace 2 through the feed pipe 14. The feed pump 13 is then activated, steadily feeding the raw material into the melting furnace 2 for melting. After melting, the molten metal is discharged through the discharge pipe 15 and enters the die-casting table 6 of the die-casting mechanism 20. At this time, the die-casting block 4, driven by the cylinder 8, moves through the telescopic rod 7, preparing for the die-casting operation. During the movement of the die-casting block 4, the buffer damping device 9 plays a crucial role in buffering. The spring damper 11 and the rubber buffer pad 12 work together to absorb the impact force during the movement of the die-casting block 4, ensuring that the die-casting block 4 can move smoothly and reducing damage to the die-casting machine caused by excessive impact force. At the same time, the human infrared sensor 16 detects the human body between the die-casting block 4 and the die-casting table 6 in real time. Once it detects that the operator's hand or other body parts have accidentally entered the area, it immediately triggers an alarm and stops the operation of the die-casting machine, effectively preventing accidents such as hand pinching.
[0030] In an emergency, the operator can quickly press the emergency stop button 17 on one side of the die-casting block 4 to immediately stop the die-casting machine, preventing further escalation of the accident and ensuring the safety of the operator. Furthermore, the design of the fixing plates 18 on the upper and lower sides of the spring damper 11 allows the spring damper 11 to be more securely connected between the die-casting block 4 and the die-casting table 6, enhancing the stability and durability of the buffer damping device 9. It also facilitates the installation and maintenance of the spring damper 11, improving the reliability and service life of the entire die-casting machine's anti-pinch device. Through the implementation of this device, the safety and stability of the die-casting machine are effectively improved, providing operators with a safer and more reliable working environment.
