Description

Technical Field

[0001] This invention relates to the field of safety protection technology for die-casting machines, and more specifically, to a fire-fighting device for die-casting machines. Background Technology

[0002] Die casting machines, as key equipment in metal forming, typically operate continuously under high temperature and high pressure. Their production process involves the transfer and injection of molten metal (such as aluminum and magnesium alloys), as well as the use of various flammable media such as hydraulic oil and lubricating oil, inherently posing extremely high risks of fire and explosion.

[0003] For example, application publication number CN119174893A discloses a fire-fighting linkage system applied to a die-casting machine, which includes a fire-extinguishing execution unit. The fire-extinguishing execution unit includes a first fire-extinguishing component and a second fire-extinguishing component, and extinguishes the fire by spraying extinguishing agent and dispersing dry powder. In the above-mentioned cases, direct spraying of extinguishing agents lacks physical isolation measures. Die-casting machine fires are often accompanied by molten metal splashing or oil flowing. Simple fire extinguishing cannot stop the spread of the fire and may lead to secondary ignition or expand the scope of the disaster.

[0004] Using fixed or simple diffusion methods to spray dry powder can be problematic because die-casting machines have complex structures, and fire sources may be hidden inside the mold, under the injection cylinder, or in gaps in hydraulic lines. Fixed spraying methods cannot ensure that the extinguishing agent accurately and fully covers and penetrates to the root of the actual fire source, resulting in incomplete extinguishing. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a fire-fighting device for die-casting machines that achieves synergy between physical isolation and suffocation fire suppression and effectively blocks the spread of fire.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A fire-fighting device for a die-casting machine includes a support platform placed inside the die-casting machine and a frame placed above the support platform. The frame and support platform are both fixedly connected inside the die-casting machine. The support platform is located on one side of the frame, and a flip plate is provided on the other side of the frame. One side of the flip plate is hinged to the frame, and the other side is movably connected to the inner wall of the die-casting machine. A chamber exists between the tilting plate, the frame, and the die-casting machine. Inside the chamber is a collection box to hold the soil pile. The collection box is fixedly connected to the inner wall of the chamber, and a discharge port with an inverted trapezoidal shape is opened inside the collection box. There is a fire extinguishing space between the tilting plate, the support platform, and the die-casting machine; this fire extinguishing space is located below the chamber. The support platform is equipped with a fire extinguishing system, which includes a cylinder, a water supply tank, and water pipes. The cylinder is fixed to the inner wall of the die-casting machine, and the cylinder output end is connected to one side of the water supply tank. The bottom of the water supply tank is slidably connected to the die-casting machine. The water pipe is located on top of the water supply tank and connected to the tank. A spray pipe is fitted onto the water pipe. The spray pipe is inclined, with one end engaging with the water pipe and rotating, and the other end passing through the flip-up plate and placed in the fire extinguishing space.

[0007] Furthermore, a temperature sensor is installed in the fire extinguishing space, a first controller is installed at the hinge connection between the flip plate and the frame, and a second controller is installed on the cylinder. Both the second controller and the first controller are connected to the temperature sensor.

[0008] Furthermore, a turntable is fitted on the outer wall of the spray pipe, and the turntable is fixedly connected to the spray pipe. A fixed seat is provided on the water pipe, and the fixed seat is fixedly connected to the outer wall of the water pipe. A hole is opened on the fixed seat, and a servo motor is provided on the inner wall of the hole. The servo motor is fixedly connected to the inner wall of the hole, and the output end of the servo motor meshes with the turntable to rotate.

[0009] Furthermore, the turntable is circular in shape, and several grooves are provided on the outer wall of the turntable, with the center of the turntable as the reference point. A connecting plate is provided on the output end of the servo motor. The connecting plate is circular in shape, and several protrusions are provided on the outer wall of the connecting plate, with the center of the connecting plate as the reference point. The protrusions are placed in the grooves and connected to the grooves.

[0010] Furthermore, it also includes lighting fixtures placed on the die-casting machine. The lighting fixtures include a first alarm light, a second alarm light, and a third alarm light. Each of the first, second, and third alarm lights is equipped with a third controller, which is connected in communication with the temperature sensor.

[0011] Furthermore, it also includes a display screen placed outside the die-casting machine, and a camera installed in the fire extinguishing space, with the camera communicating with the display screen.

[0012] Furthermore, the fire extinguishing space is equipped with a partition, which is fixedly connected to the inner wall of the fire extinguishing space. A baffle fixedly connected to the flip plate is provided on one side of the flip plate. A first magnetic block is provided on the partition, and a second magnetic block is provided on the baffle that is magnetically attracted and fixed to the first magnetic block.

[0013] Furthermore, a booster pump is installed on the water supply tank, and a fourth controller is installed on the booster pump. The fourth controller is connected in communication with the second controller.

[0014] Furthermore, a sliding groove is provided on the support platform, and a sliding plate is provided at the bottom of the water supply tank. The sliding plate is fixedly connected to the water supply tank and is placed in the sliding groove and slidably connected to the sliding groove.

[0015] Furthermore, the flip plate has through holes for the liquid spray pipe to pass through.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are as follows: 1. Achieves synergy between physical isolation and suffocation fire suppression, effectively blocking the spread of fire: The temperature sensor triggers the flip plate to open quickly, forming a physical barrier to block molten metal splashes or oil and fire flows; on the other hand, the collection box discharge port is opened simultaneously, allowing the pre-stored dry soil pile (sand) to cover the base of the fire source, achieving initial suffocation and isolation fire suppression.

[0017] 2. Improved precision delivery and coverage of extinguishing agent: The entire water supply tank and spray pipe are moved by a cylinder, combined with a servo motor-driven spray pipe rotation mechanism, allowing for flexible spraying angle and position. This multi-degree-of-freedom adjustment method ensures that the extinguishing agent fully covers and penetrates into concealed fire sources such as gaps in the die-casting machine's internal structure and under the mold.

[0018] 3. An automated, rapid, and visualized intelligent fire response system has been established: The system uses temperature sensor signals to control multiple actuators such as flip-up panels, fire extinguishing components, and alarm lights, achieving full automation from fire detection, physical isolation, automatic fire extinguishing to status alerts, with a rapid response. Simultaneously, real-time monitoring via cameras and displays facilitates remote confirmation of the fire situation and fire extinguishing effectiveness, improving the efficiency and reliability of safety management.

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in the present invention can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0023] like Figures 1 to 8 As shown, a fire-fighting device for a die-casting machine, where A represents the die-casting machine, comprises a support platform 1 and a frame 2 fixed inside the die-casting machine. A tilting plate 3 is hinged to one side of the frame 2, and the other side of the tilting plate 3 is movably connected to the inner wall of the die-casting machine, for example, via a slide rail or a detachable clip. Under normal conditions, the tilting plate 3 is perpendicular to the frame 2, together forming an upper chamber 4 with the inner wall of the die-casting machine. A collection box 401 is fixed inside the chamber 4, pre-stored with dry soil, sand, refractory fine particles, or other insulating materials. Its bottom has an inverted trapezoidal discharge port 402 to facilitate the smooth falling of the soil.

[0024] The tilting plate 3, the support platform 1, and the inner wall of the die-casting machine enclose the lower fire extinguishing space 5, which is a key area prone to fire in the die-casting machine. A temperature sensor 501 is installed inside the fire extinguishing space 5. A partition 503 can also be installed on one side of the fire extinguishing space 5, with a first magnetic block 504 embedded in the partition 503. Correspondingly, a baffle 302 is fixed to the inner side of the tilting plate 3, with a second magnetic block 303 embedded in the baffle 302. In the non-operating state, the first magnetic block 504 and the second magnetic block 303 attract each other, causing the tilting plate 3 and the partition 503 to fit tightly together, enhancing the sealing. A fire extinguishing assembly 101 is installed on the support platform 1. The fire extinguishing assembly 101 includes a cylinder 102 fixed to the inner wall of the die-casting machine, a water supply tank 103, and connected water pipes 104 and spray pipes 105. The bottom of the water supply tank 103 is slidably connected to a sliding groove 116 on the support platform 1 via a sliding plate 117. The output end of the cylinder 102 is connected to one side of the water supply tank 103, which can be pushed to move along the sliding groove 116. The water pipe 104 is vertically connected to the top of the water supply tank 103 and communicates with the inside of the tank. The spray pipe 105 is fitted onto the water pipe 104 via a rotary joint, and its end passes through a through hole 304 on the flip plate 3 at a certain angle, pointing towards the fire extinguishing space 5. A turntable 107 is fixed to the outer wall of the spray pipe 105. A mounting base 108 is fixed on the water pipe 104, which houses a servo motor 110. The output end of the servo motor 110 engages with the groove 111 on the turntable 107 via a connecting plate 112 and its protrusion 113, thereby driving the spray pipe 105 to rotate. In terms of the control system: the temperature sensor 501 is connected via wired telecommunications to a first controller 301 that controls the flip plate 3 to flip, a second controller 106 that controls the cylinder 102 to operate, a third controller that controls the alarm lights 6, and a fourth controller 115 that controls the booster pump 114. The lights 6 include a first alarm light 601, a second alarm light 602, and a third alarm light 603. The first alarm light 601 is green, the second alarm light 602 is yellow, and the third alarm light 603 is red. The first alarm light 601, the second alarm light 602, and the third alarm light 603 are installed in a prominent position on the outside of the die-casting machine. A camera 502 is also installed in the fire extinguishing space 5, which is connected to the display screen 7 on the outside of the die-casting machine for real-time monitoring.

[0025] Working principle: 1. When the die-casting machine is operating normally, if a fire source occurs in the fire extinguishing space 5, the temperature sensor 501 detects an abnormal temperature signal: Physical isolation and initial fire suppression: A signal triggers the first controller 301, driving the tilting plate 3 to tilt outward around the hinge, from a position perpendicular to (or at a certain angle to) the frame 2. This action opens the magnetic connection between the baffle 302 and the partition 503, and also causes the tilting plate 3 to extend towards the fire source area like a baffle 302, providing physical isolation and blocking. At the same time, the opening of the tilting plate 3 exposes the discharge port 402 of the collection box 401, and the pre-stored soil inside falls into the fire suppression space 5 below under gravity, covering the base of the fire source for initial suffocation and fire suppression.

[0026] II. Precise Water Spraying for Fire Extinguishing: The temperature signal simultaneously triggers the second controller 106, activating the cylinder 102, which pushes the water supply tank 103 along the slide 116 towards the fire extinguishing space 5, driving the water pipe 104 and the spray pipe 105 forward, allowing the end of the spray pipe 105 to extend further into the fire extinguishing space 5. Next, the fourth controller 115 activates the booster pump 114, pressurizing the water or extinguishing liquid in the water supply tank 103 before forcefully spraying it towards the fire source area through the water pipe 104 and the spray pipe 105. During this process, the spray pipe 105 can be rotated via the servo motor 110 to adjust the spray angle, ensuring coverage of all potential fire points.

[0027] III. Status Monitoring and Alarm: The entire fire extinguishing process can be monitored by transmitting data from camera 502 to display screen 7. Simultaneously, real-time data from temperature sensor 501 is fed back to the third controller: if the fire is extinguished and the temperature returns to normal, the first alarm light 601 illuminates (green); if residual low-temperature hazards are detected, the second alarm light 602 illuminates (yellow); if persistent high temperatures are detected or the fire is out of control, the third alarm light 603 illuminates (red), indicating the need for further intervention or manual handling.

[0028] After the fire is extinguished, the components can be manually or through the control system to be reversed to retract the flip plate 3, retract the spray pipe 105, and replenish the water supply tank 103 with water or extinguishing agent, in preparation for the next fire.

[0029] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any ordinary changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included within the protection scope of the present invention.
