Sand jet nozzle used for cold-box core shooter

Abstract

The invention discloses a sand jet nozzle used for a cold-box core shooter. The sand jet nozzle comprises a sand jet plate and a sand outlet nozzle. A hole is formed in the middle portion of the sand jet plate. The sand outlet nozzle is installed in the hole. The sand jet nozzle is characterized in that the sand outlet nozzle is detachably installed in the hole; and a fixing part is arranged on the lower portion of the sand jet plate and can fix the height, in the hole, of the sand outlet nozzle. By means of the structure that the sand outlet nozzle can be freely detached on the sand jet plate, free replacement can be conducted for molds of different specifications, and the application range is widened; and a thread is arranged in the hole in the sand jet plate, leakproofness is greatly improved compared with a traditional technology, foundry sand is prevented from leaking at the position of the hole gap between the sand outlet nozzle and the sand jet plate, and the sand-leakage-prevention technical effect is achieved.

Description

technical field [0001] The invention relates to the field of molding sand casting, in particular to a sand shooting nozzle for a cold box core shooting machine. Background technique [0002] The sand nozzle and the core shooter of the traditional cold box core shooter are an integrated structure, and the sand nozzle and the core shooter cannot be separated, so that the size of the sand inlet of the sand casting mold and the height of the mold also need to match the core shooter. [0003] In order to solve this technical problem, the height and position of the sand shooting table are generally controlled manually by the core shooter in the market, so that the sand shooting nozzle can be aligned with the sand inlet of the mold, so as to solve the problem that the sand shooting nozzle cannot be aligned with the sand injection port; however, due to The weight of the mold is relatively large, and it is only suitable for large-scale adjustments. However, for small-scale height adj...

Problems solved by technology

[0002] The sand nozzle and the core shooter of the traditional cold box core shooter are an integrated structure, and the sand nozzle and the core shooter cannot be separated, so that the size of the sand inlet of the sand casting mold and the height of the mold also need to match the core shooter

[0003] In order to solve this technical problem, the height and position of the sand shooting table are generally controlled manually by the core shooter in the market, so that the sand shooting nozzle can be aligned with the sand inlet of the mold, so as to solve the problem that the sand shooting nozzle cannot be aligned with the sand injection port; however, due to The weight of the mold is relatively large, and it is only suitable for large-scale adjustments. For small-scale height adjustments, it will undoubtedly consume a lot of manpower and material resources if adjusted according to the above technical scheme.
