Description

Technical Field

[0001] This utility model relates to the field of lost foam casting technology, and more specifically, to a lost foam coating tooling with anti-dust accumulation function. Background Technology

[0002] Lost foam casting is a casting process that uses foam plastic as a "model": a model made of foam plastic that matches the shape of the casting is made, a layer of lost foam coating is applied to its surface (the main function is to prevent sand from sticking to the casting, improve surface quality, and assist in venting, etc.), and then the molten metal is poured into the sand mold. The foam model vaporizes and disappears at high temperature, and the molten metal finally forms the casting.

[0003] A search revealed that Chinese patent CN222112211U discloses a lost foam coating spraying device. The geared motor can drive the rotating rod and the stirring paddle to rotate, thereby stirring the coating in the storage tank, preventing coating sedimentation, making the spraying more uniform, and effectively improving the practicality of the device. The movable connection between the output shaft of the geared motor and the rotating rod makes the rotating rod easy to disassemble, facilitating the cleaning and maintenance of the stirring paddle by the staff.

[0004] When the above-mentioned spraying device is in use, the paint is pushed into the telescopic hose and spray gun tube by the air compression inside the pressure tank. Finally, the pressurized paint can be atomized and sprayed out through the atomizing nozzle. However, in the foundry workshop environment, there is a lot of dust. This dust accumulates on the atomizing nozzle and will block the atomizing hole of the nozzle, resulting in uneven atomization of the paint and making it inconvenient to clean the dust on the atomizing nozzle. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lost foam coating tooling with anti-dust accumulation function, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lost foam coating fixture with anti-dust accumulation function, comprising a support frame and an atomizing nozzle, wherein the atomizing nozzle is located inside the support frame, a mounting block is fixedly connected to the rear side of the atomizing nozzle, a connecting pipe is fixedly connected to the rear side of the mounting block, a fixing frame is provided on the outer side of the mounting block, and a lifting assembly is provided between the fixing frame and the lifting assembly, the lifting assembly comprising a first stepper motor, a lead screw, a slide rod and two sliders, the first stepper motor is fixedly installed on the top of the support frame, and the output shaft end of the first stepper motor is fixedly connected to the lead screw, the top and bottom ends of the lead screw are movably connected to the support frame through bearings, the top and bottom ends of the slide rod are fixedly connected to the support frame, the two sliders are fixedly connected to the fixing frame on opposite sides, and the two sliders are respectively movably sleeved on the lead screw and the slide rod, and a high-pressure fan is fixedly connected at the center of the bottom of the support frame.

[0007] Furthermore, fixing plates are fixedly connected to the bottom edges of both sides of the support frame, wherein the fixing plates serve to facilitate the fixing of the support frame.

[0008] Furthermore, the fixed frame is provided with an adjustment assembly, which includes two rotating frames, multiple bolts, a worm gear, a worm, a rotating shaft, a second stepper motor, and a pressure plate.

[0009] Furthermore, the opposite ends of the two rotating frames are movably connected to the fixed frame via bearings, and the opposite ends of the two rotating frames are fixed to the mounting block via multiple bolts.

[0010] As can be seen, in the above technical solution, multiple bolts are rotated in sequence and moved away from the mounting block, thereby releasing the fixing between the mounting block and the two rotating frames, and allowing the mounting block to be disassembled and replaced.

[0011] Furthermore, the worm gear is fixedly sleeved on one of the rotating frames, and the front side of the worm gear meshes with the worm. The top and bottom ends of the rotating shaft are fixedly connected to the second stepper motor and the worm, respectively, and the rotating shaft is movably connected to the fixed frame through a bearing. The second stepper motor is fixedly installed on the top of the fixed frame.

[0012] Furthermore, the pressure plate is fixedly mounted on another rotating frame, and a control switch is provided at the bottom of the rotating frame.

[0013] It can be seen that the above technical solution is designed to facilitate the control of the high-pressure blower.

[0014] Furthermore, side plates are fixedly connected to both sides of the inside of the support frame, and the top of one of the side plates is fixedly connected to a control switch.

[0015] As can be seen, in the above technical solution, one side plate can support the control switch, and two side plates can enhance the deformation resistance of the support frame.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a first stepper motor to drive a lead screw to rotate, thereby moving the atomizing nozzle and mounting block downwards. The second stepper motor drives a rotating shaft to rotate, thereby rotating the atomizing nozzle and mounting block. The position of the atomizing nozzle can be adjusted according to needs, so that paint can be sprayed on different parts of the model. The high-pressure blower generates high-pressure airflow, which can remove dust from the atomizing nozzle. The operation is simple and convenient for cleaning dust from the atomizing nozzle.

[0018] 2. This utility model can drive the pressure plate to rotate through another rotating frame. When the atomizing nozzle is directly above the high-pressure blower, the pressure plate rotates exactly 90 degrees to be directly above the control switch. The lifting component drives the fixed frame and the atomizing nozzle to move downward, thereby driving the pressure plate to move downward. When the pressure plate squeezes the control switch, the control switch controls the high-pressure blower to work. The high-pressure blower removes the dust on the atomizing nozzle. The structure is simple and easy to use. Attached Figure Description

A fixing frame 5 is provided on the outer side of the mounting block 3. A lifting assembly 6 is provided between the fixing frame 5 and the lifting assembly 6. The lifting assembly 6 includes a first stepper motor 601, a lead screw 602, a slide bar 603, and two sliders 604. 01 is fixedly installed on the top of the support frame 1, and the output shaft end of the first stepper motor 601 is fixedly connected to the lead screw 602. The top and bottom ends of the lead screw 602 are movably connected to the support frame 1 through bearings. The top and bottom ends of the slide rod 603 are fixedly connected to the support frame 1. The two sliders 604 are fixedly connected to the fixed frame 5 on opposite sides, and the two sliders 604 are movably sleeved on the lead screw 602 and the slide rod 603 respectively. A high-pressure blower 8 is fixedly connected at the center of the bottom of the support frame 1.

[0028] Furthermore, fixing plates 11 are fixedly connected to the bottom edges of both sides of the support frame 1, wherein the fixing plates 11 serve to facilitate the fixing of the support frame 1.

[0029] Furthermore, the fixed frame 5 is provided with an adjustment component 7, which includes two rotating frames 701, multiple bolts 702, a worm gear 703, a worm 704, a rotating shaft 705, a second stepper motor 706, and a pressure plate 707. The opposite ends of the two rotating frames 701 are movably connected to the fixed frame 5 through bearings, and the opposite ends of the two rotating frames 701 are fixed to the mounting block 3 through multiple bolts 702. The worm gear 703 is fixedly sleeved on one of the rotating frames 701, and the front side of the worm gear 703 meshes with the worm 704. The top and bottom ends of the rotating shaft 705 are fixedly connected to the second stepper motor 706 and the worm 704, respectively, and the rotating shaft 705 is movably connected to the fixed frame 5 through bearings. The second stepper motor 706 is fixedly installed on the top of the fixed frame 5.

[0030] Furthermore, the pressure plate 707 is fixedly installed on another rotating frame 701. The bottom of the rotating frame 701 is provided with a control switch 9. The inside of the support frame 1 is fixedly connected to both sides of the side plate 10, and the top of one of the side plates 10 is fixedly connected to the control switch 9.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the two fixing plates 11 are fixed by fixing bolts, so that the support frame 1 can be installed and fixed, ensuring that the atomizing nozzle 2 remains stable during high-frequency spraying operations and avoiding the spraying position shift due to vibration. One end of the connecting pipe 4 is connected to the spray gun pipe by fixing bolts. The paint enters the mounting block 3 and the atomizing nozzle 2 through the connecting pipe 4, and finally sprays out through the atomizing nozzle 2 to coat the surface of the model with a layer of lost foam coating.

[0033] When the first stepper motor 601 is started, the first stepper motor 601 drives the lead screw 602 to rotate. Since one of the sliders 604 is threadedly connected to the lead screw 602, and the other slider 604 cooperates with the slide rod 603 to restrict the rotation of the two sliders 604 and the fixed frame 5, the lead screw 602 can drive the two sliders 604 and the fixed frame 5 to move downward, thereby driving the atomizing nozzle 2 and the mounting block 3 to move downward.

[0034] Start the second stepper motor 706. The second stepper motor 706 drives the rotating shaft 705 to rotate, which in turn drives the worm gear 704 to rotate. Since the worm gear 704 meshes with the worm wheel 703, and the worm gear 704 and the worm wheel 703 cooperate to lock the two rotating frames 701, the worm gear 704 can drive the worm wheel 703 and the two rotating frames 701 to rotate, thereby driving the atomizing nozzle 2 and the mounting block 3 to rotate. Adjust the position of the atomizing nozzle 2 as needed, so that paint can be sprayed on different parts of the model. When the atomizing nozzle 2 is located directly above the high-pressure blower 8, the high-pressure blower 8 works to generate high-pressure airflow, which can remove the dust on the atomizing nozzle 2. The operation is simple and convenient for cleaning the dust on the atomizing nozzle 2. Rotate the multiple bolts 702 in sequence and move them away from the mounting block 3, thereby releasing the fixation between the mounting block 3 and the two rotating frames 701, and disassembling and replacing the mounting block 3.

[0035] Another rotating frame 701 can drive the pressure plate 707 to rotate. When the atomizing nozzle 2 is directly above the high-pressure blower 8, the pressure plate 707 rotates exactly ninety degrees to be directly above the control switch 9. The lifting assembly 6 drives the fixed frame 5 and the atomizing nozzle 2 to move downward, thereby driving the pressure plate 707 to move downward. When the pressure plate 707 squeezes the control switch 9, the control switch 9 controls the high-pressure blower 8 to work. The high-pressure blower 8 removes the dust on the atomizing nozzle 2. The structure is simple and easy to use. At the same time, one of the side plates 10 can support the control switch 9, and the two side plates 10 can enhance the deformation resistance of the support frame 1.
