Description

Technical Field

[0001] The utility model relates to the technical field of investment casting, in particular to a lifting platform used for dipping materials. Background Art

[0002] Investment casting is to use wax to make a wax mold of the part to be cast, and then apply mud on the wax mold, which is a mud mold. When dipping, the entire wax mold needs to be immersed in ceramic slurry, and this process is done manually to avoid defects. In order to reinforce the mud, the worker covers it with zirconium sand and then lets it dry, and then repeats the process with coarser sand until the wrapped ceramic film reaches 7 mm thick. There is an application number: 201921025218.7, and the patent name is a utility model patent for a wax mold dipping shell making device, including a slurry barrel, a column that can be telescopically moved up and down by a cylinder is arranged at the center of the slurry barrel, and a plurality of blades are arranged near the bottom of the slurry barrel, and a turntable is arranged on the top of the column, and the turntable includes a circular frame and a connecting rod, one end of the connecting rod is evenly distributed along the circumference of the frame, and the other end is fixedly connected to the column, and the connecting rod and the frame are respectively provided with a plurality of hooks, and the column is fixedly connected to the slurry barrel through a fixing plate, and a driving device for driving the column to rotate is arranged at the bottom of the slurry barrel. This method has the following problems: 1. The wax parts are dipped in slurry by means of revolution, and the dip is uneven; 2. The blades in the slurry barrel need to rotate at a higher speed to ensure uniform slurry. However, when rotating at a high speed, the wax parts have a high revolution speed, which can easily throw off the slurry on the surface of the wax parts. The wax parts are unevenly dipped in slurry, and the thrown-off mud will pollute the environment.

[0003] In the published Chinese patent application, the publication number is CN218963937U, and the patent name is: A shell-making slurry-dipping rack, including a movable rack and a hanging mechanism for hooking wax pieces, the upper end of the movable rack is provided with a lifting cylinder for driving the hanging mechanism to rise and fall; the hanging mechanism includes a circular lifting plate and a plurality of rotating rods evenly arranged along the circumferential direction of the lifting plate, the rotating rods are rotatably connected to the lifting plate, the lower end of the rotating rod is provided with a hook for hooking wax pieces, and the lifting plate is provided with a driving mechanism for driving the plurality of rotating rods to rotate synchronously. During the slurry-dipping operation, the wax pieces are hung on the hook, and then the movable rack is moved to the slurry barrel, the lifting cylinder drives the lifting plate to descend, and the driving mechanism drives the plurality of rotating rods to rotate synchronously.

[0004] This prior art better simulates the manual slurry dipping operation by the self-rotation of the wax parts, ensuring that the wax parts are fully and evenly dipped in slurry. The wax parts rotate on their own and the rotation speed is adjustable. The wax parts do not need to revolve, and the slurry on the surface of the wax parts will not be thrown off. The slurry dipping is reliable and environmental pollution is prevented. Although this prior art can solve the above problems, it has certain limitations. During the specific implementation of this prior art, the wax parts will shake to a certain extent when rotating, and the wax parts are very likely to become unhooked, which seriously affects production.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments.

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a lifting platform for dipping materials, including a mounting frame 1, a dipping component is arranged on the upper part of the mounting frame 1, and the dipping component includes a lifting plate 4, a driving component and a plurality of hooking components, the driving component and the plurality of hooking components are arranged on the lifting plate 4, and the driving component is connected to each hooking component in a transmission manner. A tank body 2 is fixedly installed at the lower part of the mounting frame 1, a telescopic component 3 is fixedly installed on the mounting frame 1, and the lifting plate 4 is fixedly installed on the output shaft end of the telescopic component 3.

[0025] The tank 2 is used to hold the slurry. The telescopic member 3 is used to drive the lifting plate 4 to rise and fall. When the lifting plate 4 rises and falls, the wax pieces are driven to rise and fall. The wax pieces can be submerged in the slurry after being lifted and lowered. Each hook assembly is used to hook and fix the wax pieces. The driving component is used to drive each hook assembly to rotate on the lifting plate 4. The telescopic member 3 is a cylinder, a hydraulic cylinder, etc.

[0026] The driving assembly includes a fixed plate 5, a motor 6, a first gear 7, and a gear ring 8. The gear ring 8 is rotatably connected to the lifting plate 4. The fixed plate 5 is fixedly connected to the lifting plate 4. The motor 6 is fixedly mounted on the fixed plate 5. The first gear 7 is fixedly mounted on the output shaft end of the motor 6. The first gear 7 is meshed with the inner ring side teeth of the gear ring 8.

[0027] The motor 6 is a servo motor. After the motor 6 is started, it drives the first gear 7 located at the output shaft end thereof to rotate, and the first gear 7 drives the gear ring 8 meshing therewith to rotate.

[0028] The hook assembly includes a ring 10, a sliding shaft 11, a hook 15, and a sleeve 16. The ring 10 passes through the lifting plate 4 and the two are rotatably connected. The gear ring 8 is transmission-connected to the ring 10. The sliding shaft 11 passes through the ring 10 and the two are slidably connected (non-rotatably connected). One end of the hook 15 is fixedly connected to the lower end of the sliding shaft 11. The sleeve 16 is fixedly installed on the ring 10, and a limiting groove is provided on the sleeve 16. After sliding, the other end of the hook 15 is inserted into the limiting groove of the sleeve 16.

[0029] The gear ring 8 rotates to drive the rings 10 in each hook assembly to rotate, the rings 10 drive the sliding shaft 11 to rotate, the sliding shaft 11 drives the hook 15 to rotate, and the hook 15 drives the wax piece to rotate. When the sliding shaft 11 drives the hook 15 to slide, the open end of the hook 15 is inserted into the limit groove of the sleeve 16, so that the hook 15 is in a closed state, and the wax piece is effectively fixed in the closed loop hook 15, and the wax piece cannot be separated from the hook 15.

[0030] Specifically, the second gear 9 is sleeved on the sleeve ring 10 and the two are fixedly connected, and the second gear 9 is meshed with the outer ring side teeth of the gear ring 8.

[0031] The rotation of the gear ring 8 drives the second gear 9 meshing therewith to rotate, and the second gear 9 drives the sleeve ring 10 to rotate.

[0032] Specifically, the upper end of the sliding shaft 11 is fixedly connected with a top block 13 , and the outer side wall of the sliding shaft 11 is sleeved with a spring 12 , and the upper end of the spring 12 abuts against the top block 13 .

[0033] The spring 12 is used to push the top block 13 upward with elastic force, the top block 13 drives the sliding shaft 11 upward, and the sliding shaft 11 drives the hook 15 upward, so that the hook 15 can be continuously in an upward state, that is, the hook 15 can be in a closed state.

[0034] More specifically, a plurality of fixing blocks 14 are fixedly mounted on the mounting frame 1 , and the fixing blocks 14 correspond to the top blocks 13 in the upper and lower parts.

[0035] When the hook 15 needs to be opened, the telescopic member 3 drives the lifting plate 4 to move upward. Each hook assembly also moves upward, and when the top block 13 abuts against the fixed block 14, the top block 13 compresses the spring 12, and the top block 13 pushes the sliding shaft 11 to slide downward, and the sliding shaft 11 drives the hook 15 to move downward, and the open end of the hook 15 is separated from the limiting groove of the sleeve 16, so that the hook 15 is opened.

[0036] When in use, the telescopic member 3 drives the lifting plate 4 to move upward. Each hook assembly also moves upward. When the top block 13 abuts against the fixed block 14, the top block 13 compresses the spring 12, and the top block 13 pushes the sliding shaft 11 to slide downward. The sliding shaft 11 drives the hook 15 to move downward, and the open end of the hook 15 is disengaged from the limiting groove of the sleeve 16, so that the hook 15 is opened, that is, the right end of the hook 15 is in an open state. After hanging several wax pieces on the hook 15, start the telescopic member 3, so that the output shaft of the telescopic member 3 drives the lifting plate 4 and the model suspended on the lifting plate 4 to move downward.

[0037] When the lifting plate 4 moves downward, the lifting plate 4 is away from the top of the mounting frame 1, that is, the top block 13 is away from the fixed block 14, and at this time the spring 12 is in the reset and extended state, so the spring 12 will push the top block 13 to move upward relative to the lifting plate 4, and the top block 13 will drive the sliding shaft 11 to move upward, and the hook 15 will move upward. The hook 15 moves upward so that the open end of the hook 15 enters the limit groove of the sleeve 16 upward, and then the hook 15 is closed to prevent the wax parts from being damaged due to the subsequent unhooking during the rotation process.

[0038] The lifting plate 4 then moves downward until the lifting plate 4 covers the top of the tank body 2 , at which time the wax pieces hanging on the hooks 15 also submerge into the slurry in the tank body 2 .

[0039] Then start the motor 6, the output shaft of the motor 6 will drive the first gear 7 to rotate, the rotation of the first gear 7 will drive the gear ring 8 to rotate, the gear ring 8 drives the sleeve 10 to rotate through the second gear 9, the sleeve 10 will drive the sliding shaft 11 to rotate, and then drive the hook 15 and sleeve 16 below to rotate, so that the wax parts immersed in the tank body 2 will rotate, and the material will be self-rotated to better simulate the manual dipping operation, ensuring that the material is fully and evenly dipped.

[0040] After being dipped in slurry, the lifting plate 4 is returned to its initial position by reverse operation. When returning to its initial position, the spring 12 is compressed, and the top block 13 is pushed downward relative to the lifting plate 4 by the fixed block 14, thereby causing the hook 15 to move downward relative to the sleeve 16, so that the open end of the hook 15 is opened, making it convenient to remove the wax piece.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
