Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically a dust collection device for a die-casting machine used for automotive parts. Background Technology

[0002] Die casting is a precision casting method that uses high pressure to force molten metal into a complex-shaped metal mold. In the processing of automotive parts, in order to improve production efficiency, maintain high-precision production, and achieve the goal of mass production, die casting machines for automotive parts are usually used.

[0003] When existing die-casting machines are in operation, molten metal is usually added to the injection chamber of the die-casting machine, and then the molten metal is forced into the mold through the injection piston. Under a certain pressure, the molten metal crystallizes and solidifies to form a shape. Finally, the mold is opened to obtain the automotive parts. When the mold is opened and closed and the die-casting operation is performed, a lot of dust is generated. Some die-casting machines use vacuum cleaners to remove the dust, while others do not have independent dust collection components. After the automotive parts are processed, the workers use external vacuum cleaners to clean the inside of the die-casting machine.

[0004] Existing die-casting machines have the following problems: the former uses a vacuum cleaner to suck up metal dust, but when the sucked-up metal dust particles are large, they may clog the vacuum cleaner; the latter, although cleaned afterward, has a harsh working environment that affects the physical and mental health of employees. Therefore, we propose a dust collection device for die-casting machines used in automotive parts. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dust collection device for a die-casting machine for automotive parts. The dust collection mechanism effectively removes metal dust generated during mold opening and closing and during die-casting operations. The metal dust is intercepted by a filter screen, which avoids the normal operation of the dust collection work due to the large size of the metal dust particles. This can effectively solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for a die-casting machine for automotive parts, comprising a die-casting molding machine and a dust collection mechanism;

[0007] The dust collection mechanism includes a dust collection box, a dust collection pipe, a dust collection hood, a dust collection fan, a mounting frame, and a filter screen. The dust collection box is located in the placement compartment on the left side of the die-casting machine. A dust collection pipe is located at the feed inlet on the upper surface of the dust collection box. An adjustable sliding seat is located inside the die-casting machine. A dust collection hood is located at the right end of the dust collection pipe, passing through the sliding seat. A dust collection fan is located in the mounting hole on the front side of the dust collection box. A sliding opening is located on the left side of the dust collection box, and a mounting frame is slidably connected inside the sliding opening. A filter screen is located inside the mounting frame. The dust collection mechanism effectively removes metal dust generated during mold opening and closing and during die-casting operations. The filter screen intercepts the metal dust, preventing large metal dust particles from affecting the normal operation of the dust collection process.

[0008] Furthermore, it also includes a microcontroller, which is located outside the die-casting molding machine. The input terminal of the microcontroller is electrically connected to an external power source, and the input terminals of the die-casting molding machine and the dust extraction fan are respectively electrically connected to the output terminal of the microcontroller, which facilitates the normal operation of the equipment.

[0009] Furthermore, the dust collection mechanism also includes a fixing component, which includes a rotating shaft, a stop bar, and a placement groove. The rotating shaft is rotatably connected to the left side of the dust collection box, and the stop bar is fixedly sleeved on the outer surface of the rotating shaft. The placement groove is provided on the left side of the dust collection box, and the stop bar and the placement groove are fitted together to facilitate fixing the filter screen inside the dust collection box.

[0010] Furthermore, the dust collection mechanism also includes an air intake component, which includes an air intake channel and a dust cover. The bottom wall of the die-casting molding machine has an air intake channel, and a dust cover is provided at the front end of the air intake channel to facilitate the entry of gas into the die-casting molding machine.

[0011] Furthermore, the dust collection mechanism also includes a sealing sleeve. The sealing sleeve is fixedly fitted on the left end of the outer surface of the mounting frame. The outer surface of the sealing sleeve contacts the inner wall of the sliding opening, which facilitates sealing of the dust collection box.

[0012] Furthermore, the die-casting molding machine is equipped with evenly distributed limiting rods inside, and a sliding seat is slidably connected between the four limiting rods. An electric push rod is installed in the mounting groove on the left wall of the die-casting molding machine. The right end of the telescopic shaft of the electric push rod is fixedly connected to the left side of the sliding seat. The input end of the electric push rod is electrically connected to the output end of the microcontroller, which facilitates the mold opening and closing operation.

[0013] Furthermore, the die-casting molding machine has grooves on both the upper and lower sides of its front side, and a protective door is slidably connected between the two grooves. The front side of the protective door is equipped with a handle for easy protection during processing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This dust collection device for die-casting machines used for automotive parts has the following advantages:

[0015] The airflow first enters the die-casting machine through the dust cover and air intake channel. Then, under the action of the dust extraction fan, the airflow carries metal dust through the dust extraction cover and dust extraction pipe into the dust collection box. The airflow passes through the filter screen and is discharged from the dust collection box, while the metal dust is blocked by the filter screen and remains in the dust collection box. This can effectively remove the metal dust generated during mold opening and closing and during die-casting operations. By intercepting the metal dust through the filter screen, the normal operation of the dust extraction work is avoided due to the large size of the metal dust particles. Attached Figure Description

[0023] Please see Figure 1-5This embodiment provides a technical solution: a dust collection device for a die-casting machine for automotive parts, including a die-casting molding machine 1 and a dust collection mechanism 3. (The die-casting molding machine 1 consists of a mold closing mechanism, an injection mechanism, and a hydraulic system. The mold closing mechanism drives the die-casting mold to close and open. After the mold closes, it can provide sufficient clamping force to ensure that the mold parting surface does not expand during the injection filling process. The injection mechanism pushes the molten metal in the pressure chamber at a specified speed, allowing it to flow through the sprue and ingate in the mold, filling the mold cavity, and maintaining a certain pressure during the solidification process of the molten metal until a die-casting part is formed. After the injection action is completed, the injection punch returns to its reset position. The hydraulic system provides power and energy for the operation of the die-casting machine, ensuring that the mold closing mechanism, injection mechanism, and other parts can work normally.) It also includes a single-chip microcomputer 2, which is located outside the die-casting molding machine 1. The input end of the single-chip microcomputer 2 is electrically connected to an external power source. The interior of the die-casting molding machine 1 is equipped with uniformly distributed... The four limit rods 4 are slidably connected to a sliding seat 5. An electric push rod 6 is provided in the mounting groove on the left wall of the die casting machine 1. The right end of the telescopic shaft of the electric push rod 6 is fixedly connected to the left side of the sliding seat 5. The input end of the electric push rod 6 is electrically connected to the output end of the microcontroller 2. The upper and lower sides of the front side of the die casting machine 1 are provided with sliding grooves 7. A protective door 8 is slidably connected between two sliding grooves 7. The front side of the protective door 8 is provided with a handle 9. The operator moves the protective door 8 to the right along the sliding groove 7 by using the handle 9. Then, the microcontroller 2 is operated to open the electric push rod 6. The electric push rod 6 drives the sliding seat 5 to move to the right along the limit rods 4 until the mold is closed. Then, the die casting machine 1 is opened to perform die casting processing of automotive parts. Molten metal is added to the injection chamber of the die casting machine 1. Then, the molten metal is injected into the mold by the injection piston. Under a certain pressure, the molten metal crystallizes and solidifies to form a shape. Finally, the mold is opened to obtain automotive parts.

[0024] The dust collection mechanism 3 includes a dust collection box 31, a dust collection pipe 32, a dust collection hood 33, a dust collection fan 34, a mounting frame 35, and a filter screen 36. The dust collection box 31 is located in the placement compartment on the left side of the die-casting machine 1. (A hinged door is connected to the left side of the dust collection box 31; a sealing strip on the right side of the door ensures its sealing when closed; a door lock is located at the junction of the door and the dust collection box 31, using a common door lock connection method in the prior art.) A dust collection pipe 32 is located at the feed inlet on the upper surface of the dust collection box 31. An adjustable sliding seat 5 is located inside the die-casting machine 1. The right end of the dust collection pipe 32 passes through the sliding seat 5 and is fitted with a dust collection hood 33. The front side of the dust collection box 31... A vacuum cleaner fan 34 is installed inside the mounting hole. A sliding opening is provided on the left side of the dust collection box 31. A mounting frame 35 is slidably connected inside the sliding opening. A filter screen 36 is installed inside the mounting frame 35. The input ends of the die-casting molding machine 1 and the vacuum cleaner fan 34 are electrically connected to the output ends of the microcontroller 2, respectively. The vacuuming mechanism 3 also includes a fixing component 37, which includes a rotating shaft 371, a baffle 372, and a placement groove 373. The rotating shaft 371 is rotatably connected to the left side of the dust collection box 31. The baffle 372 is fixedly sleeved on the outer surface of the rotating shaft 371. The placement groove 373 is provided on the left side of the dust collection box 31. The baffle 372 and the placement groove 373 are fitted together. The vacuuming mechanism 3 also includes an air intake component 38, which includes an air intake channel 38. 1. A dust cover 382 is provided at the bottom wall of the die-casting machine 1. An air inlet channel 381 is provided at the front air inlet of the air inlet channel 381. The dust collection mechanism 3 also includes a sealing sleeve 39. The sealing sleeve 39 is fixedly fitted on the left end of the outer surface of the mounting frame 35. The outer surface of the sealing sleeve 39 contacts the inner wall of the slide. Metal dust is generated when the mold is opened and closed and when the die-casting operation is performed. At the same time, the dust collection fan 34 is turned on. The airflow first enters the die-casting machine 1 through the dust cover 382 and the air inlet channel 381. Then, under the action of the dust collection fan 34, the airflow carries the metal dust together and is sucked into the dust collection box 31 through the dust collection cover 33 and the dust collection pipe 32. The airflow passes through the filter screen 36 and is discharged from the dust collection box 31. 1. Metal dust is trapped in the dust collection box 31 by the filter screen 36. After the die-casting machine 1 has been working for a period of time, the operator can open the switch door to clean the metal dust collected inside the dust collection box 31. When the filter screen 36 needs to be cleaned, rotate the stop bar 372 clockwise. The stop bar 372 rotates around the pivot 371. The placement groove 373 is a U-shape with an opening on the upper side. Continue until the stop bar 372 leaves the placement groove 373. Then, the mounting frame 35 can be pulled out along the sliding opening to remove the filter screen 36 for cleaning. After cleaning, reinsert the filter screen into the dust collection box 31 and then rotate the stop bar 372 counterclockwise until the stop bar 372 rotates into the placement groove 373. This will fix the filter screen 36 in the dust collection box 31.

[0025] The working principle of the dust collection device for a die-casting machine for automotive parts provided by this utility model is as follows: The operator moves the protective door 8 to the right along the slide 7 using handle 9, then controls the microcontroller 2 to open the electric push rod 6. The electric push rod 6 drives the sliding seat 5 to move to the right along the limit rod 4 until the mold is closed. Then, the die-casting machine 1 is opened for die-casting of the automotive parts. Molten metal is added to the injection chamber of the die-casting machine 1, and then the molten metal is injected into the mold through the injection piston. Under a certain pressure, the molten metal crystallizes and solidifies to form the part. Finally, the mold is opened to obtain the automotive part. Metal dust is generated during mold opening and closing and during the die-casting operation. Simultaneously, the dust collection fan 34 is turned on. The airflow first enters the die-casting machine 1 through the dust cover 382 and the air intake channel 381. Then, under the action of the dust collection fan 34, the airflow carries… Moving metal dust is drawn into the dust collection box 31 through the dust suction hood 33 and the dust suction pipe 32. The airflow passes through the filter screen 36 and is discharged from the dust collection box 31, while the metal dust is blocked by the filter screen 36 and remains in the dust collection box 31. After the die-casting molding machine 1 has been working for a period of time, the operator can open the switch door to clean the metal dust collected inside the dust collection box 31. When the filter screen 36 needs to be cleaned, the stop lever 372 is rotated clockwise. The stop lever 372 rotates around the rotating shaft 371. The placement groove 373 is a U-shape with an opening on the upper side. The stop lever 372 is rotated until it leaves the placement groove 373. Then the mounting frame 35 can be pulled out along the sliding opening to remove the filter screen 36 for cleaning. After cleaning, the filter screen is reinserted into the dust collection box 31. Then the stop lever 372 is rotated counterclockwise until it rotates into the placement groove 373, thus fixing the filter screen 36 in the dust collection box 31.

[0026] It is worth noting that the die casting molding machine 1 disclosed in the above embodiments can be an MT300 cold chamber die casting machine, the single-chip microcomputer 2 can be an EFR32MG21, the dust extraction fan 34 can be an SF series axial flow fan, and the single-chip microcomputer 2 controls the operation of the die casting molding machine 1, the dust extraction fan 34 and the electric push rod 6 using methods commonly used in the prior art.
