Embodiment Construction
[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0030] Please refer to Figure 1 to Figure 5 , a leak-proof sand shooting head, comprising a sand shooting board 1 and a baffle 2, the baffle 2 is installed on the sand shooting board 1, and a core sand supply is provided between the baffle 2 and the sand shooting board 1 10 flow gap, the sand shooting plate 1 is equipped with a sand shooting head 3, the sand shooting head 3 is provided with a sand shooting port 9, and the outer side of the sand shooting port 9 is provided with a downwardly inclined annular groove An adjustment rod 5 is installed on the baffle plate 2 above the sand injection port 9, and the lower end of the adjustment rod 5 is provided with an annular protrusion, and the inclination angle of the an...

The invention relates to the technical field of hot core box sand shooting, in particular to a sand leakage prevention sand shooting head which comprises a sand shooting plate and a baffle. The baffle is installed on the sand shooting plate, a gap for core sand to flow is formed between the baffle and the sand shooting plate, a sand shooting head is installed in the sand shooting plate, a sand shooting opening is formed in the sand shooting head, an annular groove is formed in the outer side of the sand shooting opening, an adjusting rod is installed on the baffle above the sand shooting head, an annular protrusion is arranged at the lower end of the adjusting rod, and the annular protrusion and the annular groove are the same in inclination angle and are arranged at intervals. According to the sand leakage prevention sand shooting head, through the arrangement of the annular groove, leaked sand after sand shooting can be contained, it is avoided that the leaked sand falls on a core box and is heated to form hard blocks, and the workload of cleaning the core box is reduced; and the distance between the annular protrusion and the annular groove can be adjusted by arranging the adjusting rod, so that the sand shooting speed is adjusted, the core sand is ensured to be full, and the workload of solid waste removing is reduced.
Description
technical field [0001] The invention relates to the technical field of hot core box sand shooting, in particular to a leak-proof sand shooting head. Background technique [0002] The resin-coated sand core shot by the hot core box core shooter has the advantages of fast forming speed, smooth appearance of the sand core, convenient cleaning, and good surface quality of the casting, and is widely used in small and medium-sized castings with complex geometric shapes and smooth surfaces. production. When making sand cores, the resin-coated sand in the sand-shooting head of the hot-core box core-shooting machine injects the coated sand into the cavity of the sand core mold through the sand-shooting head under the action of air pressure. The core sanding head of the existing hot core mechanism is easy to leak sand after the sand shooting is finished, and it is easy to form a hard block on the core box when it is heated; at the same time, there are poor sealing during sand shootin...
