Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sand core dipping, in particular to a chuck assembly used for sand core dipping. Background Art
[0002] Before pouring the engine sand core, in order to ensure the smoothness of the outer surface of the sand core, the sand core needs to be transferred to a dipping tank for dipping. During the dipping process, the sand core needs to be turned over to remove excess liquid coating.
[0003] In the prior art, a sand core is usually clamped by a clamp to complete the dipping operation of the sand core. However, due to the deviation of the insertion position of the clamp and the looseness of the sand core, broken sand will be generated at the clamping position of the sand core, and fall into the coating tank during the dipping process, thereby affecting the cleanliness of the coating in the dipping tank. Therefore, it is urgent to study a clamp assembly for sand core dipping to solve the above problems. Utility Model Content
[0004] The utility model provides a chuck assembly for sand core dipping, and its purpose is to solve the technical problems raised in the above background technology.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0006] The utility model discloses a chuck assembly for sand core dipping, wherein a pair of sink grooves are arranged side by side on opposite sides of the sand core; the chuck assembly comprises a pair of connecting brackets respectively arranged on opposite sides of the sand core; a sand core clamping plate parallel to the opposite sides of the sand core is fixed on the two connecting brackets; a pair of anti-rotation chucks corresponding to the sink grooves are fixed side by side on the opposite inner surfaces of the two sand core clamping plates; sealing rings in a rectangular frame structure are arranged on the outer peripheries of the two pairs of anti-rotation chucks; the two pairs of sealing rings are respectively fixed on the opposite inner surfaces of the two sand core clamping plates; when the anti-rotation chucks are plugged into the sink grooves, the sink grooves are located on the inner sides of the sealing rings.
[0007] As a preferred technical solution of the utility model, the relative inner surfaces of the two sand core clamping plates are provided with sand accumulation grooves in a rectangular frame structure; the sand accumulation grooves are arranged between the anti-rotation chuck and the sealing ring, and the sand accumulation grooves are arranged at the root of the anti-rotation chuck.
[0008] The utility model has the following beneficial effects:
[0009] The utility model slides and inserts two pairs of anti-rotation chucks into two pairs of sink grooves respectively, and makes the relative inner surfaces of the two sand core clamping plates fit with the relative side surfaces of the sand core respectively, so that the sink groove is located on the inner side of the sealing ring. Therefore, during the dipping process of the sand core, the sealing strip and the sand accumulation groove can effectively prevent the broken sand generated by clamping from falling into the coating groove, which not only maintains the cleanliness of the coating, but also prevents the problem of coating impurities adhering to the surface of the sand core, and at the same time effectively guarantees the dipping quality of the sand core, and has a high market application value.
