Technical Field
[0001] The utility model belongs to the technical field of core shooting machines, and particularly relates to a sand-proof shooting plate device for casting core shooting. Background Art
[0002] The shooting plate assembly is a key component of a core shooter. Existing core shooter assembly consists of a shooting plate, a spacer, and a sand retaining plate. The entire assembly is mounted on a shooting head. The shooting plate has a shot opening. The sand retaining plate is secured to the spacer and blocks the shot opening. The shooting head is secured to the outer edge of the shooting plate, forming a cavity with the plate. This cavity is filled with coated sand.
[0003] Since the coated sand on the inside of the nozzle does not automatically flow out in a static state due to the accumulation angle principle, when the shooting plate device moves with the shooting head, the coated sand inside the shooting head will be scattered from the nozzle due to vibration, which not only causes a large amount of coated sand to be wasted, but also the coated sand will be solidified by heat after being scattered on the mold, which increases the workload of subsequent manual cleaning. In addition, the bottom of the existing shooting plate device is often in contact with the template, and long-term use may cause damage to the shooting plate. For this reason, we propose a non-leakage sand shooting plate device for casting core shooting. Utility Model Content

When the nozzle on the sand baffle 71 matches the nozzle on the shooting plate 1, the coated sand in the shooting head 2 will fall from the nozzle, avoiding the waste of the coated sand leaking from the nozzle when the shooting plate 1 moves with the shooting head 2. A bottom plate 4 is provided, and the bottom plate 4 is made of rubber material, which can reduce the bumps and collisions of the shooting plate 1 when it contacts the mold surface, avoid damage to the surface of the shooting plate 1 after long-term use, and increase the service life of the shooting plate 1.
[0024] Furthermore, four groups of nozzles are symmetrically opened on the surfaces of the shooting plate 1, the sand retaining plate 71 and the bottom plate 4. Only when the nozzles on the surfaces of the shooting plate 1, the sand retaining plate 71 and the bottom plate 4 are aligned, the coated sand will fall from the nozzles.
