Technical Field

[0001] The present application relates to the field of casting technology, and in particular to a wax mold sizing device. Background Art

[0002] The sand shell mold is a commonly used casting mold. Its manufacturing process mainly includes the following steps: the wax mold is immersed in the sizing equipment through a robotic arm to make the slurry evenly cover the surface of the wax mold. After coating the slurry, dry sand is sprinkled for reinforcement. The slurry is coated layer by layer and dried layer by layer to obtain a sand shell with a total thickness of 2~4mm.

[0003] In the related art, the sizing equipment includes a sizing barrel, in which silica sol as a slurry is arranged, and the bottom of the sizing barrel is rotatably connected to a stirring mechanism, and the stirring mechanism is connected to a driving member, which drives the stirring mechanism to rotate at the bottom of the sizing barrel to prevent the slurry from depositing or agglomerating, thereby facilitating sizing of the wax model.

[0004] The above technical solution still has the following defects: the stirring shaft arranged at the center of the bottom of the slurry barrel will occupy a certain space, thereby limiting the immersion range of the wax model, which may cause the wax model to be unable to be completely immersed in the slurry. Utility Model Content

[0005] In order to optimize the slurry dipping range of the wax model, the present application provides a wax model sizing device.

[0006] The present application provides a wax model sizing device, which adopts the following technical solution:

[0007] A wax model sizing device comprises a base, a sizing barrel connected to the base, a stirring mechanism rotatably connected to the sizing barrel, and a driving mechanism connected to the sizing barrel, wherein the stirring mechanism is arranged on the side of the sizing barrel, the driving mechanism comprises a gear set, a synchronous wheel connected to the gear set, and a motor connected to the synchronous wheel, a synchronous belt is connected between the motor and the synchronous wheel, and the gear set is connected to the bottom of the sizing barrel.

[0008] By adopting the above technical solution, the stirring shaft is located on the side of the sizing barrel, which can enable the wax model to obtain a larger slurry dipping range, so that the wax model can fully contact the slurry during the slurry dipping process. At the same time, the stirring mechanism can provide a larger stirring range and stirring intensity during the stirring process, so as to quickly mix the slurry evenly and improve production efficiency.

[0009] Optionally, the gear set includes a first gear and a second gear meshing with the first gear, the first gear is connected to the sizing barrel, the second gear is coaxially connected to the synchronous wheel, and the first gear and the second gear are both arranged in the base.

[0010] By adopting the above technical solution, the motor drives the synchronous wheel to rotate, the synchronous wheel drives the second gear to rotate coaxially, the second gear drives the first gear to rotate, and the first gear drives the sizing barrel to rotate. The use of the motor-driven gear can realize automatic control, reduce manual intervention, and thus improve production efficiency. The operation of the motor-driven gear is relatively simple. The rotation of the sizing barrel can be achieved by adjusting the speed and direction of the motor without too many complicated operations. In addition, the first gear and the second gear are arranged inside the base, which is relatively stable and safe during operation, and the maintenance cost is relatively low.

[0011] Optionally, the stirring mechanism includes a positioning column and a stirring shaft connected to the positioning column, the positioning column is connected to the base, the stirring shaft is arranged in the sizing barrel, the stirring shaft includes a main shaft and a transverse support arm connected to the main shaft, the end of the main shaft away from the transverse support arm is connected to the positioning column, the main shaft is vertically arranged along the side wall of the sizing barrel, and the transverse support arm is horizontally arranged along the bottom wall of the sizing barrel.

[0012] By adopting the above technical solution, the stirring shaft extends from the opening of the sizing barrel along the side wall to the bottom, which can maximize the stirring range and improve the stirring efficiency. It can ensure that the slurry at the bottom is fully stirred during the stirring process, and can effectively avoid dead corners at the bottom of the sizing barrel. It is less likely to cause uneven mixing or certain slurries cannot be stirred, thereby achieving a more uniform mixing effect and reducing the waste of slurry and the difficulty of cleaning.

[0013] Optionally, the positioning column is connected with a connecting piece, a fastener is connected between the connecting piece and the main shaft, a waist-shaped hole is formed on the connecting piece for the fastener to pass through, and a through hole is formed on the main shaft for the fastener to pass through.

[0014] By adopting the above technical solution, on the one hand, the stirring shaft and the positioning column can be detachably connected, which is convenient for cleaning and maintenance, keeping the equipment clean and sanitary, and extending the service life of the equipment; on the other hand, by moving the position of the fastener, the relative position of the stirring shaft in the sizing barrel can be adjusted, thereby improving the applicability and flexibility of the equipment.

[0015] Optionally, the positioning column includes a column body, the column body is connected to the base, an adjusting member is provided on the column body, and the adjusting member is connected to the main shaft.

[0016] By adopting the above technical solution, the height of the stirring shaft can be adjusted.

[0017] Optionally, the adjusting member includes a handwheel and a screw connected to the handwheel, the screw is threadedly connected to the column, a limiting cylinder is sleeved on the outer side of the screw, the column is sleeved on the outer side of the limiting cylinder, and the limiting cylinder is connected to the connecting piece.

[0018] By adopting the above technical solution, the hand wheel is turned to drive the screw to rotate in the column. Through the limiting effect of the limiting cylinder and the column, the connecting piece and the limiting cylinder slide down in the vertical direction, so as to achieve the height adjustment of the stirring shaft. The adjusting part has a compact structure, occupies a small space, and realizes the precise control of the stirring shaft position.

[0019] Optionally, both sides of the main shaft and the transverse support arm are bent to form bent portions.

[0020] By adopting the above technical solution, the main shaft and the lateral support arm are in a U-shaped structure, which can provide better stirring and mixing effects. The U-shaped structure can increase the surface area of ​​the stirring shaft, so that more contact with the slurry can be made per unit time, thereby improving the stirring efficiency. Compared with the traditional vertical structure, the U-shaped structure will generate less resistance during stirring, so it can reduce energy consumption and power consumption.

[0021] Optionally, a side piece is connected to the side of the main shaft away from the bending portion.

[0022] By adopting the above technical scheme, on the one hand, the combined effect of the side panels and the main shaft makes it easy to scrape off the slurry on the side wall of the sizing barrel, and the side wall agglomeration phenomenon is not easy to occur; on the other hand, the structural strength of the main shaft is enhanced. Since the liquid slurry has a certain viscosity, the main shaft may be subject to resistance from the slurry when it moves relatively in the slurry. Therefore, the rigidity of the main shaft is increased by the side panels to prevent the main shaft from deforming and twisting.

[0023] Optionally, a protective cover is provided on the outer side of the sizing barrel.

[0024] By adopting the above technical solution, the protective cover is used for protection. When the motor controls the sizing barrel to rotate, on the one hand, the protective cover plays a role of safety protection, which can effectively prevent the staff from accidentally contacting the rotating sizing barrel and reduce the risk of accidental injury; on the other hand, the protective cover plays a role of equipment protection, reducing the possibility of damage to the sizing barrel and extending the service life of the equipment.

[0025] Optionally, a liquid level detector is provided on the protective cover.

[0026] By adopting the above technical solution, the liquid height detector can detect the liquid level in the sizing barrel. Once the liquid level exceeds or falls below the set value, the detection instrument can automatically adjust the feed through the feedback signal to keep the liquid level stable within the set range. Automatically controlling the liquid level can reduce manual intervention, improve production efficiency, and ensure the stability and consistency of the liquid level during continuous production, minimizing safety hazards.

[0027] In summary, this application has the following beneficial effects:

[0028] 1. By setting a stirring shaft, the wax model can obtain a larger immersion range to ensure that the wax model can fully contact the slurry during the immersion process. The stirring mechanism can provide a larger stirring range and stirring intensity during the stirring process, so as to quickly mix the slurry evenly and improve production efficiency;

[0029] 2. By setting up a driving mechanism, automatic control can be achieved, manual intervention can be reduced, and production efficiency can be improved. The operation of the motor-driven gear is relatively simple. The rotation of the sizing barrel can be achieved by adjusting the speed and direction of the motor without the need for excessive complex operations. BRIEF DESCRIPTION OF THE DRAWINGS
