Description

Technical Field

[0001] This utility model relates to the field of AAA technology, specifically to a complete control cabinet for a boxless molding machine. Background Technology

[0002] As a key piece of equipment in casting production, the flaskless molding machine relies on a complete control cabinet for automated control during operation. The stable operation of the control cabinet directly affects the production efficiency and product quality of the molding machine. Since flaskless molding machines often operate in dusty industrial environments, the electronic components inside the control cabinet generate a large amount of heat during high-frequency operation. If heat dissipation is not timely, it can easily lead to accelerated component aging or even short-circuit failures. Therefore, heat dissipation performance is one of the core design indicators of the control cabinet.

[0003] Traditional control cabinets typically use a cooling fan combined with side vents for ventilation and heat dissipation. However, after prolonged use, dust easily accumulates on the filter plates at the vents, which not only clogs ventilation channels and reduces heat dissipation efficiency but may also affect the insulation performance of internal components due to dust penetration. Existing control cabinets often have fixed filter plates or require periodic manual disassembly and cleaning. When the filter plates become clogged, the machine must be stopped for cleaning, severely impacting production continuity. Therefore, this invention proposes a complete control cabinet for a boxless molding machine, solving the aforementioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, such as easy clogging of filter plates in control cabinets and the need for machine shutdown for cleaning, an automatic vibration cleaning of filter plates is achieved by setting up cam one, cam two and a reset mechanism, combined with door panel linkage and servo motor drive. This avoids manual disassembly and cleaning and machine shutdown operations, ensuring heat dissipation efficiency and production continuity.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a complete control cabinet for a boxless molding machine, including a cabinet body, an open outer wall on one side of the cabinet body, and a door panel rotatably connected to the open outer wall. An observation window is installed on the outer wall of the door panel. A cooling fan is installed on the top of the cabinet body. A heat dissipation groove is opened on the side wall of the cabinet body, and a frame is installed at the opening of the heat dissipation groove. A filter plate is movably connected inside the frame. A second cam and a first cam are rotatably connected to the top and bottom of the frame, respectively. A reset mechanism is installed inside the frame.

[0008] The reset mechanism is used to drive the filter plate to reset.

[0009] Preferably, the reset mechanism includes multiple sets of fixing plates fixedly connected to the inner walls on both sides of the frame. The multiple sets of fixing plates are symmetrically arranged in pairs and form a pair. A sliding rod is fixedly connected between each pair of fixing plates. The filter plate is slidably connected to the outer wall of each set of sliding rods. Two sets of springs are sleeved on the outer wall of the sliding rods.

[0010] Preferably, one end of each set of springs is fixedly connected to the filter plate, and the other end of each set of springs is fixedly connected to the outer wall of its adjacent fixed plate.

[0011] Preferably, a first transmission wheel and a second transmission wheel are rotatably connected to the upper end of the cabinet. The first transmission wheel is connected to the second transmission wheel via a transmission belt. The first transmission wheel is coaxially and fixedly connected to the rotating shaft on its adjacent door panel. The second transmission wheel is coaxially and fixedly connected to the second cam.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a complete control cabinet for a boxless molding machine, which has the following advantages:

[0016] 1. This utility model, through the cooperation of cam one, cam two and reset mechanism, can automatically generate vibration when dust accumulates on the filter plate surface. The slide rod ensures smooth sliding of the filter plate, and the spring quickly drives the filter plate to reset. The filter plate can be cleaned without stopping the machine, solving the problem of traditional control cabinets requiring machine stoppage for disassembly and cleaning of filter plates, ensuring production continuity, and avoiding dust clogging the filter plate and affecting heat dissipation.

[0017] 2. This utility model forms an efficient heat dissipation channel through a cooling fan and a heat dissipation groove with a filter plate. The filter plate blocks dust from entering the cabinet and protects the electronic components. The door panel linkage drive cam 2 through drive wheel 1 and drive wheel 2, combined with cam 1 controlled by a servo motor. The filter plate can be cleaned without additional complex drive components, reducing equipment energy consumption and solving the problems of high energy consumption and complex structure of traditional cleaning mechanisms. It takes into account both heat dissipation efficiency and operating cost. Attached Figure Description

[0023] This utility model provides a technical solution for a complete control cabinet for a boxless molding machine:

[0024] Please see Figure 1-3 The complete control cabinet for the boxless molding machine includes a cabinet body 1. One side of the outer wall of the cabinet body 1 is open, and a door panel 2 is rotatably connected to the open side. An observation window is installed on the outer wall of the door panel 2. A cooling fan 3 is installed on the top of the cabinet body 1. A heat dissipation groove is opened on the side wall of the cabinet body 1, and a frame 4 is installed at the opening of the heat dissipation groove. A filter plate 8 is movably connected inside the frame 4. A second cam 14 and a first cam 13 are rotatably connected to the top and bottom of the frame 4, respectively. A reset mechanism is installed inside the frame 4.

[0025] The reset mechanism is used to drive the filter plate 8 to reset;

[0026] Furthermore, by setting a cooling fan 3 on the cabinet 1 in conjunction with a heat dissipation slot with filter plate 8, the heat dissipation efficiency inside the cabinet 1 can be improved. The combination of cam 13, cam 24 and the reset mechanism can achieve vibration cleaning of filter plate 8 without adding a complex drive structure, effectively avoiding the clogging problem of filter plate 8 caused by dust accumulation.

[0027] The reset mechanism includes multiple sets of fixing plates 9 fixedly connected to the inner walls on both sides of the frame 4. The multiple sets of fixing plates 9 are symmetrically arranged in pairs and form a pair. Each pair of fixing plates 9 is fixedly connected to a slide rod 10. The filter plate 8 is slidably connected to the outer wall of each set of slide rods 10. Two sets of springs 11 are sleeved on the outer wall of the slide rod 10.

[0028] Furthermore, the slide bar 10 provides stable guidance for the sliding of the filter plate 8, preventing the filter plate 8 from shifting or jamming during vibration, while the spring 11 provides power for the reset of the filter plate 8.

[0029] One end of each set of springs 11 is fixedly connected to the filter plate 8, and the other end of each set of springs 11 is fixedly connected to the outer wall of its adjacent fixed plate 9.

[0030] Furthermore, the two ends of the spring 11 are connected to the filter plate 8 and the fixed plate 9 respectively, so that when the filter plate 8 is subjected to the force of the first cam 13 and the second cam 14, the spring 11 can produce corresponding elastic deformation. After the external force disappears, the filter plate 8 is quickly driven to reset. This connection method allows the elastic force of the spring 11 to act evenly on the filter plate 8, ensuring the stability of the reset process.

[0031] The upper end of the cabinet 1 is rotatably connected to a first transmission wheel 5 and a second transmission wheel 6. The first transmission wheel 5 is connected to the second transmission wheel 6 via a transmission belt 7. The first transmission wheel 5 is coaxially and fixedly connected to the rotating shaft on its adjacent door panel 2. The second transmission wheel 6 is coaxially and fixedly connected to the second cam 14. The radius of the first transmission wheel 5 is larger than that of the second transmission wheel 6. The first cam 13 and the second cam 14 have the same size, and their flanges are in contact with the outer wall of the filter plate 8.

[0032] Furthermore, the rotation of the door panel 2 drives the first transmission wheel 5 to rotate, and transmits the rotation to the second transmission wheel 6 via the transmission belt 7, thereby driving the second cam 14. There is no need to set up an additional power source to drive the second cam 14, which reduces the energy consumption of the equipment.

[0033] A servo motor 12 is fixedly connected to the lower end of the frame 4, and the output shaft of the servo motor 12 is fixedly connected to the cam 13 on the same axis.

[0034] Furthermore, the servo motor 12 can precisely control the rotation frequency and angle of the cam 13, and can flexibly adjust the vibration intensity according to the dust accumulation of the filter plate 8, so as to ensure the cleaning effect while avoiding excessive vibration that could damage the filter plate 8. In addition, in conjunction with the cam 2 14 driven by the door panel 2, different cleaning cycles can be selected according to the usage requirements.

[0035] In practical use, the working principle of this utility model is as follows:

[0036] When the complete control cabinet of the boxless molding machine is in normal working condition, the electronic components inside the cabinet 1 generate heat. At this time, the cooling fan 3 on the top of the cabinet 1 starts, and air convection is formed through the heat dissipation grooves on the side wall of the cabinet 1. The outside air enters the cabinet 1 after being filtered by the filter plate 8 in the frame 4, which carries away the heat and is discharged from the cooling fan 3, thus achieving efficient heat dissipation. The filter plate 8 can also block the entry of external dust and prevent the internal components from being contaminated.

[0037] When the operator needs to check the interior of cabinet 1, they rotate door panel 2 to open it. During the rotation of door panel 2, transmission wheel 5, which is fixed coaxially with its shaft, rotates synchronously. This drives transmission wheel 6 to rotate via transmission belt 7, which in turn causes cam 14, which is coaxial with transmission wheel 6, to rotate. Since the radius of transmission wheel 5 is larger than that of transmission wheel 6, door panel 2 only needs to rotate a small angle to cause cam 14 to rotate a large amplitude. Its flange repeatedly contacts filter plate 8, creating an inward thrust on filter plate 8.

[0038] Meanwhile, the servo motor 12 at the lower end of the frame 4 can be activated according to the dust accumulation on the filter plate 8, driving the cam 13 to rotate. The cam 13 and the cam 2 14 are the same size, and apply a pushing force to the filter plate 8 from below. Under the alternating force of the two sets of cams, the filter plate 8 slides back and forth along the slide rod 10. At this time, the spring 11 on the outer wall of the slide rod 10 undergoes elastic deformation as the filter plate 8 moves: when the filter plate 8 slides to one side, the spring 11 on one side is compressed and the spring 11 on the other side is stretched. After the pushing force of the cam disappears, the elastic force of the spring 11 quickly drives the filter plate 8 to return to its original position, ensuring that the filter plate 8 slides smoothly on the slide rod 10 without jamming.

[0039] This dual-drive design, combined with a reset mechanism, causes the filter plate 8 to vibrate at high frequency, shaking off the dust adhering to the surface and achieving automatic cleaning.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
