Description

Technical Field

[0001] The utility model relates to the technical field of sand dropping devices, in particular to a sand dropping device for casting. Background Art

[0002] As an important part of the manufacturing industry, the casting process has a direct impact on the development of the entire industry due to its technical level and production efficiency. In the casting process, sand removal is an indispensable part, the purpose of which is to remove the sand on the surface of the casting for subsequent cleaning and processing.

[0003] Existing sand-falling devices usually use vibration or impact to remove the sand on the surface of the casting and recycle the sand. For the agglomerated sand, the agglomerates cannot be completely broken up, and due to the existence of agglomerated sand, the recycling rate of the sand is greatly reduced. The sand that cannot be recycled needs to be processed at an additional cost, which not only wastes resources, but also increases the production cost of the enterprise. For this reason, we propose a sand-falling device for casting. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand falling device for casting, comprising a U-shaped fixed plate, two movable blocks are slidably installed on the outer side of the U-shaped fixed plate, a discharge box is fixedly installed between the two movable blocks, a sand falling box is fixed on the top of the discharge box, the discharge box is communicated with the inside of the sand falling box, and a sand filter is fixedly installed at the discharge port of the discharge box;

[0006] An elastic part is arranged between the inner side of the U-shaped fixed plate and the discharge box, a resistance plate is fixedly installed on one side of the discharge box, a driving component for pushing the resistance plate to move is arranged on the inner side of the U-shaped fixed plate, a rotating rod is movably installed through the bottom of the discharge box, a gear is fixedly installed on the lower end of the rotating rod, a connecting rod is installed on one side of the U-shaped fixed plate, a ruler bar meshing with the gear is fixedly installed on one end of the connecting rod, and a crushing component is arranged on the end of the rotating rod located in the discharge box.

[0007] Preferably, a grid bed is fixedly installed inside the shakeout box.

[0008] Preferably, the elastic member is specifically one or more springs, one end of the spring is fixedly mounted on the inner side of the U-shaped fixing plate, and the other end of the spring is fixedly mounted on one side of the discharge box.

[0009] Preferably, the driving assembly includes a mounting plate, the mounting plate is welded to the inner side of the U-shaped fixing plate, a motor is mounted on the bottom surface of the mounting plate, the motor output end passes through the mounting plate, a cam is fixedly mounted on the motor output end, and the cam is tangent to one side of the contact plate.

[0010] Preferably, the crushing assembly comprises a moving rod and a plurality of crushing rods, the moving rod is fixedly mounted on one end of the rotating rod, and the crushing rod is fixedly mounted on the outside of the moving rod.

[0011] Preferably, the moving rod and the crushing rod are located at a narrowed portion of the discharge box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The sand falling device for casting fixes the casting on the surface of the grid bed, turns on the switch of the motor, drives the cam to rotate, and under the tension of the spring, the contact plate can remain tangent to the outer side of the cam, so that during the rotation of the cam, the discharge box and the sand falling box can drive the movable block to slide back and forth at high speed on the outer side of the U-shaped fixed plate, so that the discharge box and the sand falling box vibrate, and the sand falling box drives the grid bed and the casting to vibrate, so that the molding sand falls. After the molding sand enters the discharge box, the uncaked molding sand passes through the filter sand net and leaves the discharge box. The filter sand net vibrates under the driving action of the discharge box, thereby improving the sand filtering efficiency.

[0014] 2. In the casting sand falling device, the agglomerated molding sand cannot pass through the sand filter net, and thus remains in the narrow mouth of the discharge box. As the movable block drives the discharge box to reciprocate, the gear can make the relative ruler reciprocate, and the gear can drive the rotating rod and the moving rod to reciprocate, and drive the crushing rod to reciprocate to crush the agglomerated molding sand in the narrow mouth of the discharge box, thereby improving the recovery rate of molding sand and reducing the cost of molding sand recovery.
