[0001] The utility model belongs to the technical field of shot blasting machines, in particular to a double-hanging-point hook with a labyrinth seal. Background Art

[0002] Shot blasting machine refers to casting equipment that uses high-speed projectiles thrown by shot blasting machine to clean or strengthen the surface of castings. Shot blasting machine can simultaneously remove sand, core and clean castings. Shot blasting machine is a processing technology that uses shot blasting machine to throw steel sand and steel shot at high speed to impact the surface of material objects. Compared with other surface treatment technologies, it is faster and more effective, and can be used to treat the casting process after partial retention or stamping. Shot blasting machine can also remove surface contaminants from a partially coated surface and provide a surface profile that increases the adhesion of the coating to achieve the purpose of strengthening the workpiece.

[0003] The sealing of the hook of the traditional lifting shot blasting machine is that a small umbrella-shaped cover plate is installed on the hook. The umbrella-shaped cover of the hook is not enough to seal the projectile ejection area, so that the projectile splashes out of the room roof from the opening of the stretched sealing curtain. Utility Model Content

[0006] The shot blocking mechanism includes a mounting frame inserted into the entry groove, a sealing plate is fixedly installed inside the mounting frame, the sealing plate is located inside the entry groove, a top plate is fixedly installed at the bottom of the sealing plate, two L-shaped round rods are symmetrically fixedly connected between the bottom of the top plate and the mounting frame, the outer sides of the two L-shaped round rods are movably sleeved with the same lifting plate, the bottom of the lifting plate is symmetrically fixedly connected to two connecting plates, a baffle plate 1 is fixedly connected between the bottoms of the two connecting plates, and the baffle plate 1 is located inside the shot blasting chamber.

[0007] Preferably, two baffle plates 2 are symmetrically fixedly connected to the inner top wall of the shot blasting chamber, an abutment plate is fixedly connected between the two baffle plates 2, the mounting frame is fitted with the abutment plate, and the baffle plate 1 is located between the two baffle plates 2.

[0008] Preferably, two rubber plates are symmetrically fixedly mounted on the bottom of the baffle plate 1, and the two rubber plates are respectively fitted with the two baffle plates 2.

[0009] Preferably, two springs are symmetrically fixedly connected between the lifting plate and the top plate, and the two springs are respectively sleeved on the outsides of the two L-shaped round rods.

[0010] Preferably, a lifting ring is provided directly below the lifting plate, the lifting ring is movably sleeved on the outside of the two L-shaped round rods, two cylinders are symmetrically fixedly installed between the lifting ring and the top plate, and the lifting plate is located between the two cylinders.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The utility model facilitates the two rubber plates to fit with the two baffle plates 2 respectively through the cooperation between the lifting plate and the L-shaped round rod and the connecting plate and the spring, and then the projectiles are doubly blocked by the baffle plates 2 and 1, and the interior of the installation frame is sealed by the sealing plate, thereby preventing the projectiles from splashing out through the entry slot;

[0013] (2) The new type facilitates the lifting of the lifting ring by cooperating between the cylinder, the lifting ring and the L-shaped round rod. When the lifting ring rises, the lifting plate drives the baffle plate 1 to move upward. At the same time, the two springs are compressed, which facilitates the baffle plate 1 to enter between the two baffle plates 2. When the lifting ring descends, the limit on the lifting plate can be released, which facilitates the two springs to reset and drive the lifting plate to move downward, thereby facilitating the two rubber plates to fit the two baffle plates 2 respectively to prevent projectiles from splashing.
