Description

Sand box sand adding assembly line of lost foam casting part

Technical Field

The utility model relates to a casting manufacturing field, concretely relates to sand box of disappearance mould casting adds sand assembly line.

Background

The flask for lost foam casting plays a very important role in the lost foam casting process. The box body is formed by combining steel plates, channel steel, stainless steel meshes, grid bars and the like, and has elegant appearance and durability.

Baidu encyclopedia of: the sand box is a key device in the lost foam casting production and is divided into a complex sand box, a simple sand box and the like according to different purposes. The complex sand box can achieve the most reasonable negative pressure field when the casting is vacuumized in the sand box, so that the full-box casting can be well molded without defects. For some castings with simple shapes and low requirement on the uniformity of a negative pressure field during pouring, a simple sand box can be adopted; the design is mainly based on the actual situation of the customer.

The complex sand box does not need to vibrate, the compaction work of the sand is completed through negative pressure suction, but in order to save cost, the simple sand box is not suitable for negative pressure equipment, and the compacted sand needs to tamp the sand in the sand box by vibration so as to ensure the structural strength of the sand mould and the smoothness of the joint surface of the sand mould and the model.

The invention patent with the application number of CN202111236664.4 discloses a casting process, which comprises the following steps: s1, manufacturing a casting model according to the equal size of a casting part; s2, processing the model; s3, oppositely combining the two sand boxes at the left side and the right side, and placing the model in the centers of the two sand boxes; s4, simultaneously adding casting sand into the two sand boxes to bury the model, compacting the casting sand, transversely separating the two sand boxes, taking out the model, and combining the two sand boxes to obtain a sand mold cavity; s5, heating metal for casting to be in a liquid state, and then casting the metal into a sand mold cavity; s6, separating the two sand boxes after cooling, taking out the casting and processing to obtain a casting workpiece; the casting process uses a casting device which comprises a support, a sand box, a model fixing mechanism and a sand pressing mechanism.

The equipment of the sand in the jolt sand box that still needs to use in above-mentioned process, for example the chinese utility model patent application no: disclosed in cn202020524408.x is a movable sand box jolt ramming device, still such as utility model patent no: ZL202220133977.0 discloses a three-dimensional jolter for a sand turning box, which is convenient for a model to be fully attached to sand.

The sand adding process needs to add sand, the sand adding process is compact, the sand supplementing process is needed after the sand adding process is compact, enough sand is ensured to guarantee the shape of the model, the sand adding process is generally a working position in the existing factory equipment, the sand in the jolt sand box is a working position, the working positions are switched back and forth, and the sand adding process is inconvenient if meeting the situation that the sand adding process needs to be compact. According to the retrieval situation, equipment for automatically adding sand, automatically compacting after adding sand and replenishing sand after compacting is lacked.
