Description

Technical Field

[0001] The utility model belongs to the technical field of core shooting machines, in particular to a sand shooting nozzle for a core shooting machine. Background Art

[0002] The core shooter uses compressed air to evenly shoot molding sand into the sand box for pre-compaction, and then applies pressure for compaction. When the core shooter is in operation, the sand barrel is pressed against the upper surface of the core box by the compaction cylinder, and the sand is shot through the sand shooting nozzle after the sand shooting valve is opened. The sand core is preheated in the core box and quickly hardened to a certain thickness before being taken out, forming a high-quality sand core product with a smooth surface and precise size.

[0003] The top end of the sliding panel also is provided with an interlocking structure, and the interlocking structure is fixed with a toothed structure, and the toothed structure is connected with a toothed structure in an inner wall of the sliding panel and the toothed structure is fixed with a toothed structure.

[0004] The existing core shooting machine uses a sand shooting nozzle that is difficult to seal between the sand shooting nozzle and the sand box, resulting in sand leaking from between the sand shooting nozzle and the sand box and flying everywhere during sand shooting, affecting the processing environment. It is also difficult to extract and clean the excess sand remaining on the top of the sand box, causing sand to accumulate on the core shooting machine, thereby reducing the efficiency of the core shooting machine. Therefore, an internal leveling machine for pipe making is proposed to solve the above problems. Utility Model Content

Specific embodiment 1

[0029] See also Figure 1-3The utility model is a sand shooting nozzle for a core shooting machine, comprising a sand shooting nozzle 100 and a sealing assembly 200; a sealing assembly 200 is provided at the bottom end of the sand shooting nozzle 100, the sealing assembly 200 comprises a sealing mechanism 210, a circular scraper 220 and a sliding mechanism 230, the sealing mechanism 210 comprises a sleeve 210a, a spring 210b, a sealing cover 210c, a rectangular groove 210d and a rectangular sealing ring 210e, the sliding mechanism 230 comprises a fixed block 230a, a fixed plate 230b and a sliding rod 230c, thereby achieving the purpose of sealing between the sand shooting nozzle 100 and the sand box.

[0030] Specifically, the sliding mechanism 230 is fixedly installed between the sand shooting nozzle 100 and the sealing mechanism 210, the circular scraper 220 is fixedly installed at the top of the sealing mechanism 210, and the circular scraper 220 contacts the inner wall of the sand shooting nozzle 100, the rectangular sealing ring 210e is embedded in the inside of the rectangular groove 210d, the rectangular groove 210d is opened at the bottom of the sealing cover 210c, the sealing cover 210c is fixedly installed at the bottom of the sleeve 210a, the sleeve 210a is sleeved on the bottom end of the sand shooting nozzle 100, the upper and lower ends of the spring 210b are respectively fixedly connected to the sand shooting nozzle 100 and the sleeve 210a, the sliding rod 230c slides through the fixed plate 230b, and the fixed plate 230b is fixedly installed on the outer wall of the sand shooting nozzle 100, the fixed block 230a is relatively fixedly installed on both sides of the sleeve 210a, and the top of the fixed block 230a is fixedly connected to the bottom end of the sliding rod 230c.

[0031] The operation process of this embodiment is as follows: when the sand box is being sand-shot molded, the core shooter adjusts the sand-shooting nozzle 100 to contact the sand box. When the sand-shooting nozzle 100 contacts the sand box, the rectangular sealing ring 210e contacts the top of the sand box. The linkage sleeve 210a slides on the bottom end of the sand-shooting nozzle 100, the spring contracts, and the slide bar 230c slides on the fixed plate 230b. The squeezing force of the spring makes the seal between the rectangular sealing ring 210e and the sand box more precise, which is used to prevent sand from leaking from between the sand-shooting nozzle 100 and the sand box during sand shooting.

[0032] When the sleeve 210a slides on the bottom end of the sand shooting nozzle 100 , it pushes the circular scraper 220 to slide on the inner wall of the sand shooting nozzle 100 to scrape and clean the sand on the inner wall of the sand shooting nozzle 100 . Specific embodiment 2
