Problems solved by technology

[0003] In foundry production, when using the hot core box core shooter, it is necessary to use the auxiliary shooting cylinder for sand shooting operation, and the structure of the sand shooting cylinder is relatively complicated, so it is very troublesome to make, and a lot of time is wasted, and the production efficiency is very low. Low, and the use of this sand shooting cylinder is also very cumbersome, and it needs to be cleaned frequently, so the use efficiency is very low, and the labor intensity of the workers is high, which cannot meet the requirements of modern production, so further improvement is needed

Embodiment Construction

[0012] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the sand shooting device includes a cylinder body 1, and the cylinder body 2 is fixed on a support frame 6. The upper end of the cylinder 2 is provided with a trumpet-shaped sand filling port 1, which can facilitate the injection of molding sand. The lower end of the cylinder 2 is provided with a nozzle 5, and the upper part of the cylinder 1 forms an air blowing chamber 3. The air blowing chamber 3 It communicates with the sand filling port 1, and the blowing cavity 3 is filled with high-pressure gas. The lower part of the cylinder body 2 forms a lower injection cavity 4, and the lower injection cavity 4 communicates with the blowing cavity 3 and the injection head 5 respectively.

[0014] When the sand shooting device is in use, the molding sand is added into the cylinder through the sand filling port. Whe...

Abstract

The invention discloses a sand shooting device. The device comprises a cylinder body, wherein a sand feeding port is formed at the upper end of the cylinder body, and a shooter is arranged at the lower end of the cylinder body; an air blowing cavity is formed at the upper part of the cylinder body and is communicated with the sand feeding port; high-pressure air is introduced in the air blowing cavity; and a lower shooting cavity is formed at the lower part of the cylinder body, and is communicated with the air blowing cavity and the shooter respectively. When the sand shooting device is used, casting sand is added into the cylinder body through the sand feeding port; and when the casting sand passes through the air blowing cavity at the upper part of the cylinder body, the casting sand accelerates under the action of high-pressure air, and are shot out from the shooter through the lower shooting cavity so as to complete the whole sand shooting process. The sand shooting device has a simple structure, and is easy to manufacture and very convenient to use, so that the production efficiency can be effectively improved, the labor intensity of workers is reduced, and the modern production requirement is met.

Description

technical field [0001] The invention relates to the field of casting, in particular to a sand shooting device used on a hot core box core shooting machine. Background technique [0002] In the modern casting production process, in order to improve the casting efficiency and meet the requirements of modern production, most of the cores used in the casting process are manufactured by hot core box core shooters, which are widely used in the foundry machinery industry. The core made by the hot core box core shooter has the advantages of accurate size and smooth surface, so it is widely used in many foundry companies. [0003] In foundry production, when using the hot core box core shooter, it is necessary to use the auxiliary shooting cylinder for sand shooting operation, and the structure of the sand shooting cylinder is relatively complicated, so it is very troublesome to make, and a lot of time is wasted, and the production efficiency is very low. Low, and this sand shooting...
