Sealed height-adjustable sand shooting mouth

Abstract

The invention discloses a sealed height-adjustable sand shooting mouth. The sealed height-adjustable sand shooting mouth comprises a sand shooting chamber pipe, and a sand shooting plate; the sand shooting plate is provided with a groove matching the sand shooting chamber pipe; the sand shooting chamber pipe is capable of sliding in the groove vertically; a horizontal screw hole is arranged in the sand shooting plate, and the side wall of the sand shooting chamber pipe is penetrated by the horizontal screw hole; and a fastening screw matching the horizontal screw hole is arranged in the horizontal screw hole. The structure of the sealed height-adjustable sand shooting mouth is ingenious; the fastening screw is used for fastening the sealed height-adjustable sand shooting mouth; when the height of the sealed height-adjustable sand shooting mouth should be adjusted based on the demands of users, height adjusting can be realized via unscrewing, heightening, and screwing; operation is simple and convenient; and in addition, a sealing rubber ring is arranged at an outlet of the groove of the sand shooting plate, so that sand leakage caused by loose fixing of the sand shooting chamber pipe with the sand shooting plate is avoided, wherein loose fixing of the sand shooting chamber pipe with the sand shooting plate may be caused by loss caused by frequent adjusting of the sealed height-adjustable sand shooting mouth.

Description

technical field [0001] The invention relates to the field of foundry machinery, in particular to a sealed and height-adjustable sand injection nozzle. Background technique [0002] In the field of foundry machinery, the cold core machine core technology is a widely used high-efficiency core making technology, so the process of injecting molding sand into the mold has become a necessary part of the cold core machine core process, so the sand injection machine has also become a cold core machine core technology. The necessary machinery of technology. [0003] Since different core-making molds have different heights, the sand shooting outlet of the core shooting machine (that is, the sand shooting nozzle) must also match the height of the mold, so as to avoid the deviation of the sand shooting caused by the distance between the sand shooting nozzle and the mold. Damage to the nozzle. [0004] In order to solve the above problems, the traditional technology generally directly ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the traditional technology generally directly replaces the sand injection nozzle to adapt to the height of the mold. The replacement process is complicated and takes a long time. Frequent replacement will cause sand leakage at the edge due to the loss of the sand injection nozzle.

Moreover, the spare shot nozzle is easy to lose due to its small size, which seriously affects the production efficiency
