Simple and practical tool for adsorbing sand grains in cavity

Technical Field

The utility model relates to the technical field of casting modeling, in particular to a simple and practical tool for adsorbing sand grains in a cavity.

Background

In the clay sand casting molding process, before the mold cavity is prepared and the mold closing is finished, an important step is provided, namely, air guns are used for blowing floating sand in the mold cavity or sand grains falling into the mold cavity, if the floating sand is not blown completely, the manufactured casting necessarily has sand hole defects, the appearance quality of the casting is affected, and the sand hole defects seriously cause the scrapping of the casting.

Therefore, in clay sand molding, the sand grains in the cavity are usually blown clean by using an air gun, and for products with complex sand cores in the cavity, the sand grains are difficult to blow clean by using the air gun, so that a tool with accurate adsorption type needs to be designed.

Publication (bulletin) number: CN103394655B, publication (date): 2016-01-06 provides a sand sucking tip having a tip body having: the inlet end of the air inlet channel is connected with the compressed gas storage device; one end of the air outlet channel is communicated with the outlet end of the air inlet channel; one end of the sand suction channel is communicated with the junction of the air inlet channel and the air outlet channel. One end of the sand sucking channel is communicated with the intersection of the air inlet channel and the air outlet channel, when compressed gas with certain pressure enters the air inlet channel and is discharged through the air outlet channel, the inner cavity of the sand sucking channel can form negative pressure suction, sand in the cavity is sucked out, sand sucking is realized immediately, and the sand sucking head is simple in structure, easy to process and convenient to carry and can adapt to various occasions.

However, the above technology is different from the structure of the utility model, so that the blocking problem is easy to be caused, and the technical problem to be solved and the realized beneficial effects are different.
