Description

Technical Field

[0001] The present application relates to the field of lost foam, and in particular to a coating device for lost foam. Background Art

[0002] Lost foam casting (also known as full-mold casting) is a new casting method that uses a foam plastic mold with binder-free dry sand combined with vacuum technology. It is a foam model with a similar size and shape to the casting that is bonded together into a model cluster, coated with refractory paint and dried, then buried in dry quartz sand for vibration molding, poured under negative pressure, vaporized the model, and liquid metal occupies the model position, which solidifies and cools to form a casting.

[0003] Since the density of the foam plastic is relatively small and it cannot be completely sunk into the refractory coating, workers are still required to apply the refractory coating on the surface of the foam plastic, which puts a lot of labor intensity on the workers. Utility Model Content

[0004] In order to reduce the labor intensity of the staff, the present application provides a coating device for lost foam process.

[0005] The present application provides a coating device for lost foam process, which adopts the following technical solution:

[0006] A coating equipment for lost foam process, including a cylinder for holding coating, an immersion assembly and a lifting assembly, the immersion assembly including a limit plate, a receiving plate and a connecting rod, the limit plate is horizontally arranged, the receiving plate is horizontally arranged, the receiving plate is located below the limit plate, the connecting rod is used to connect the receiving plate and the limit plate, a plurality of through holes are formed on the limit plate and the receiving plate, and the lifting assembly is used to drive the immersion assembly to move toward the cylinder.

[0007] By adopting the above technical solution, the staff places the foam plastic to be coated with paint between the receiving plate and the limiting plate. The receiving plate and the limiting plate move toward the cylinder under the action of the lifting component until the limiting plate is immersed in the paint. The through holes allow the paint to cover the surrounding side of the foam plastic, thereby increasing the coating area of ​​the foam plastic. After the foam plastic is coated with paint, the lifting component moves the receiving plate and the limiting plate toward the direction away from the cylinder, and the staff can take out the foam plastic that has been coated with paint. The immersion component has a simple structure, which greatly reduces the workload of the staff.

[0008] Optionally, a plurality of toggle rods for toggling the foam plastic are provided on the limit plate, the toggle rods are located on the side of the limit plate facing the receiving plate, the toggle rods are slidably connected to the limit plate, a plurality of limit grooves are provided on the inner side of the cylinder, the plurality of limit grooves correspond one-to-one to a plurality of toggle rods, the limit grooves are wavy in the vertical direction, and the limit grooves are used for the sliding of the toggle rods.

[0009] By adopting the above technical solution, the density of the foam plastic is lower than the density of the coating. Therefore, as the two immersion components enter the cylinder, the foam plastic will always abut against the limit plate. Although the through hole will bring the coating into contact with the surface of the foam plastic contacting the limit plate, the limit plate will always be partially in contact with the foam plastic, resulting in the inability to be covered by the coating. This problem can be solved by a toggle rod. When the limit plate enters the cylinder, the toggle rod on the limit plate enters the limit groove. Since the limit groove is wavy, the toggle rod will toggle the foam plastic when the limit plate moves toward the bottom of the cylinder. The position of the foam plastic and the limit plate changes, and the area of ​​the foam plastic coated with coating increases.

[0010] Optionally, a stirring assembly for driving the paint to impact the foam plastic is provided in the cylinder, and the stirring assembly includes a stirring motor and a stirring paddle, the stirring paddle is rotatably connected to the bottom of the cylinder, and the stirring motor is used to drive the stirring paddle to rotate.

[0011] By adopting the above technical solution, the agitator is used to drive the paint to stir in the barrel body. When the foam plastic enters the barrel body under the action of the immersion component, the paint will be in motion, and the paint will impact on the foam plastic, changing the position of the foam plastic relative to the limit plate, so that the foam plastic has better contact with the paint. The paint moves in the barrel body, so that the paint can better penetrate the foam plastic, thereby increasing the speed of applying the paint to the foam plastic.

[0012] Optionally, the limit plate is slidably connected to the connecting rod, and the immersion assembly also includes a control member for controlling the distance between the limit plate and the receiving plate, the control member includes a fixed rod and a control nut, the length direction of the fixed rod is parallel to the length direction of the connecting rod, one end of the fixed rod is arranged on the limit plate, the receiving plate is slidably connected to the fixed rod, the control nut is threadedly connected to the fixed rod, and the control nut is rotatably connected to the receiving plate.

[0013] By adopting the above technical solution, due to the different sizes of foam plastics, it is necessary to adjust the distance between the limit plate and the receiving plate, thereby improving the applicability of the immersion assembly. When the staff needs to adjust the distance between the limit plate and the receiving plate, the staff can rotate the control nut, and the control nut moves on the fixed rod. The control nut drives the receiving plate to move in the length direction of the fixed rod. Since the limit plate is set on the fixed rod, the distance between the receiving plate and the limit plate changes. The control component has a simple structure and is easy for the staff to operate.

[0014] Optionally, the lifting assembly includes a lifting platform and a lifting cylinder, the lifting platform is arranged on one side of the cylinder body, the cylinder body of the lifting cylinder is arranged on the lifting platform, and the fixing rod is arranged on the piston rod of the lifting cylinder.

[0015] By adopting the above technical solution, when the foam plastic needs to be coated with paint, the staff first places the foam plastic in the immersion component, and then the staff can control the lifting cylinder, the piston rod of the lifting cylinder extends, and the immersion component enters the cylinder body. When the foam plastic is finished coating with paint, the staff retracts the piston rod of the lifting cylinder, and the immersion component is detached from the cylinder body. The lifting component has a simple structure and is easy for the staff to operate.

[0016] Optionally, a shaking assembly for shaking off paint is arranged on the fixed rod, and the shaking assembly includes a mounting block, a sliding block and a driving member. The mounting block is arranged on the piston rod of the lifting cylinder, the sliding block is arranged on the fixed rod, the sliding block is slidably connected to the mounting block, and the driving member is used for the sliding block to slide back and forth in the vertical direction on the mounting block.

[0017] By adopting the above technical solution, when the foam plastic coated with paint is taken out from the cylinder, there will be excess paint still on the foam plastic. The staff can use a shaking assembly to shake the excess paint on the foam plastic into the cylinder. The staff starts the driving member, and the driving member drives the sliding block to reciprocate in the vertical direction relative to the mounting block. The excess paint enters the cylinder under the action of gravity and inertia, which reduces the waste of paint and ensures the cleanliness of the factory.

[0018] Optionally, the driving member includes a driving motor and a cam, the cam is rotatably connected to a fixed rod, the sliding block is slidably connected to a side wall of the cam, and the driving motor is used to drive the cam to rotate.

[0019] By adopting the above technical solution, the driving motor drives the cam to rotate, and the sliding block is slidably connected to the outer wall of the cam. Since the distances from the outer wall of the cam to the output axis of the driving motor are different, the driving motor drives the sliding block to move relative to the mounting block during the process of driving the cam to rotate. The driving motor can drive the cam to rotate quickly, and the cam can drive the sliding block to move quickly relative to the mounting block. The immersion assembly as a whole shakes up and down quickly to shake off excess paint on the foam plastic.

[0020] Optionally, a rotating assembly is provided on the lifting platform, and the rotating assembly includes a rotating seat, a rotating motor, a first gear and a second gear. The lifting platform is connected to the rotating seat for rotation in a vertical direction. The first gear is arranged on the rotating axis of the lifting platform, the rotating motor is arranged on the rotating seat, and the second gear is arranged on the output shaft of the rotating motor, and the first gear is meshed with the second gear.

[0021] By adopting the above technical solution, since the immersion component needs to extend out of the cylinder before the foam plastic can be taken out, but the cylinder is located at a high position, it is inconvenient for the staff to put in and take out the foam plastic. The staff can start the rotating motor, and the rotating motor drives the second gear to rotate, and the second gear drives the first gear to rotate, and the first gear drives the lifting platform to rotate on the rotating seat, so that the vertical projection of the immersion component is offset from the cylinder. After that, the staff extends the piston rod of the lifting cylinder and lowers the height of the immersion component, which is convenient for the staff to remove the foam plastic that has been coated with paint and place the foam plastic that needs to be coated later on the immersion component.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The immersion component is used to completely immerse the plastic foam in the cylinder, reducing the workload of the staff;

[0024] 2. The toggle rod is used to drive the foam plastic to move relative to the limit plate in the cylinder, further increasing the application area of ​​the foam plastic;

[0025] 3. The shaking component is used to shake off the excess paint on the applied foam plastic. BRIEF DESCRIPTION OF THE DRAWINGS
