Description

Technical Field

[0001] The utility model belongs to the technical field of non-ferrous metal investment casting, and particularly relates to a cleaning device for a wax pattern module. Background Technique

[0002] Investment casting, also known as the lost wax process, has the greatest feature that the surface dimensional accuracy and surface finish of the cast parts are very high, and they can be directly used without machining or with very little machining, which is an advanced near-net shaping process. The main process flow of investment casting is as follows: process design - wax pattern making - cleaning - shell preparation - dewaxing - roasting - mold assembly - melting and pouring.

[0003] Cleaning is an important link in the investment casting process. In order to remove the parting agent, wax chips, etc. attached to the surface of the investment pattern and improve the coating property (wettability) of the coating on the module, cleaning should be carried out after the module combination. The cleaning liquid and water are injected into the cleaning tank according to a certain ratio, and then the module is placed in the cleaning tank for soaking for a certain time, and then taken out and cleaned with clean water.

[0004] However, during the process of placing multiple wax patterns into the cleaning tank, the modules will collide due to the flow of the liquid, resulting in chipping, fracture and deformation of the wax patterns. Moreover, the cleaning liquid in the ordinary cleaning tank does not flow, and when cleaning the wax patterns with some small cavity structures, it is not easy to clean evenly. Therefore, it is necessary for a special person to hold the wax pattern and rotate it back and forth for cleaning, and each person can only hold 1 set, which greatly increases the labor cost and reduces the production efficiency. When the cleaning liquid is used multiple times, it will become ineffective and new cleaning liquid needs to be replaced. After the conventional cleaning tank discharges the cleaning liquid, there will still be residues of the ineffective cleaning liquid at the bottom, which will contaminate the new cleaning liquid, reduce the service life of the cleaning liquid, and increase the labor cost and time for cleaning the cleaning tank. Content of the Utility Model

[0005] To solve the above problems, the utility model provides a cleaning device for a wax pattern module, which fixes and arranges the modules to avoid collision damage and deformation between the modules; the design of the device improves the cleaning quality of the wax pattern and significantly improves the production efficiency.

[0026] Embodiment 1:

[0027] As shown in the figure, a wax mold module cleaning device includes a cleaning tank 1 and an ejection mechanism, a wax mold fixing support frame 4, a stirrer 6, and a bottom tank 9 located inside the cleaning tank 1;

[0028] The wax mold fixing support frame 4 is horizontally fixed above the ejection mechanism, and the ejection mechanism provides power for the wax mold fixing support frame to ensure that the wax mold fixing support frame 4 can move up and down smoothly, improving the cleaning rate. The ejection mechanism includes four groups of air cylinders 3 and guide posts 2. The air cylinders 3 are respectively installed at the four corners of the cleaning tank 1. The guide posts 2 are connected to the air cylinders 3, and the wax mold fixing support frame 4 is fixed on the guide posts 2.

[0029] The bottom tank 9 is located at the bottom of the cleaning tank 1. The stirrer 6 passes through the bottom tank 9 so that its top is located above the bottom tank 9. The bottom of the bottom tank 9 is connected to a drainage system 7 for discharging the cleaning liquid. The drainage system 7 is composed of a water pipe with a valve. The stirrer 6 is fixedly supported by a side wall support frame 8 located at the bottom.

[0030] The bottom tank 9 is a conical square tank, which is formed by welding 5 tapered steel plates. The bottom tank can also be of other shapes. A drainage hole and a stirrer installation hole are provided in the middle of the bottom of the tank. The conical design at the bottom can facilitate the smooth discharge of the cleaning liquid and avoid residual waste liquid in the tank; the stirring impeller can make the cleaning liquid flow in a certain direction and speed, cleaning the wax mold more quickly and evenly.

[0031] A filter net 5 is also provided between the wax mold fixing support frame 4 and the stirrer 6. The filter net 5 is composed of a 200-mesh stainless steel net with support plates added around it, aiming to filter the wax chips and other substances washed off the wax mold and ensure the cleanliness of the cleaning liquid.

[0032] The mixer 6 includes a mixing impeller, a mixing shaft, a shaft seal, a transmission, a frame, and a reducer. The rotation of the mixer drives the flow of the cleaning liquid, enabling faster cleaning of the wax mold.

[0033] The wax mold fixing support frame 4 is made of stainless steel plate processed into a hollow grid. The shape of the hollow part of the grid is composed of connected circles and squares. The width of the square groove in the grid is designed according to the size of the handle of the module to ensure that the handle can pass through the square groove without shaking. The diameter of the round groove is designed according to the diameter of the gasket on the handle to ensure that the gasket can pass through the round groove. Four corners of the wax mold fixing support frame 4 are provided with cylinder fixing holes for connecting the guide posts.

[0034] Working process:

[0035] First, fix the wax mold on the grid of the wax mold fixing support frame 4. Then, start the mixer 6 to stir the cleaning liquid. Then, control the lifting of the guide post 2 through the pressure of the cylinder 3, thereby controlling the lifting of the wax mold fixing support frame 4 with the wax mold fixed on it. When the wax mold group is immersed in the cleaning liquid, the cleaning liquid impacts the wax mold group, and the wax skin, oil stains, etc. on the wax mold group are washed away.
