AI Technical Summary
In existing casting processes, especially in V-process casting, it is difficult to clean foreign objects from the mold cavity of the casting sand mold. In particular, it is difficult to completely clean the small areas of complex structures, resulting in time-consuming and labor-intensive cleaning work.
A simple tooling for cleaning the cavity of a casting sand mold was designed, including a foreign matter discharge pipe and a rubber base. The foreign matter discharge pipe consists of a vertical pipe section and an inclined pipe section. The air inlet is located on the inclined pipe section. Compressed air is used to clean foreign matter in the cavity through the air inlet. The rubber base prevents the tooling from contacting and damaging the sand mold.
It achieves efficient cleaning of foreign objects in complex cavities, simplifies the cleaning process, improves production efficiency, and is suitable for the cavity cleaning needs of V-process casting.

Description
TECHNICAL FIELD
[0001] The utility model belongs to tooling technical field, especially relate to a simple tooling of casting sand mould cavity cleaning. BACKGROUND
[0002] V method casting and lost foam casting all adopt vacuum forming, but the process flow of both has big difference, the biggest advantage of distinguishing traditional sand casting is not using binder, V method casting is sealed sand box by plastic film, removes the air in the mould by vacuum pumping system, there is pressure difference between the inside and outside of the mould, makes dry sand dense, forms required cavity, through core, closes the box, pours and extracts vacuum to make the casting solidify, removes the negative pressure, and the sand collapses to obtain the casting. Current foundry industry develops rapidly, and the structure of the produced castings also presents the complex trend, which leads to the cavity formed by molding in the casting process is more and more complex; in the production process, there are inevitably foreign matters in the cavity, especially in the narrow area, which is difficult to clean, and the cleaning work is time-consuming and laborious, so a special tooling is needed to improve the production efficiency. CONTENT OF THE UTILITY MODEL
[0003] The utility model aims at providing a simple tooling of casting sand mould cavity cleaning to solve the problems in the above background.
[0004] The utility model discloses a simple tooling of casting sand mould cavity cleaning, including foreign matter discharge pipe and rubber base, the foreign matter discharge pipe includes vertical pipe section and oblique pipe section, the top of vertical pipe section is integrally formed with oblique pipe section, and the head of oblique pipe section is provided with foreign matter discharge outlet, the top of rubber base is provided with pipe connection sleeve, the rubber base is connected with the bottom of vertical pipe section through pipe connection sleeve, and the connecting place of vertical pipe section and oblique pipe section is provided with air inlet on oblique pipe section.
[0005] In the simple tooling of casting sand mould cavity cleaning, the vertical pipe section and the oblique pipe section are integrally formed, and the vertical pipe section and the oblique pipe section are 45 DEG.
[0006] In the simple tooling of casting sand mould cavity cleaning, the air inlet is one-way air inlet eye structure.
[0007] In the simple tooling of casting sand mould cavity cleaning, the bottom of the rubber base is provided with sandstone inlet.
[0008] Compared with the prior art, the simple tool for cleaning the sand mold cavity of the casting has the advantages that the top of the vertical pipe section is integrally formed with the inclined pipe section, the head of the inclined pipe section is provided with a foreign matter discharge outlet, the rubber base is connected with the bottom end of the vertical pipe section through the pipe connection sleeve, the connection between the vertical pipe section and the inclined pipe section is provided with an air inlet on the inclined pipe section, and the cleanliness of the complex area in the cavity can be ensured; the foreign matter in the narrow cavity can be cleaned without repeated actions.
