Problems solved by technology

[0002] In the casting molding automatic line, after the molding of the static pressure molding machine is completed, due to the poor air permeability of the sand tire, the exhaust gas and other gases generated during pouring cannot be discharged, and the castings after pouring will have defects such as pores. The pistol drill does not exhaust the exhaust gas well, which not only wastes a lot of manpower, but also the effect is not ideal

Abstract

The invention provides an air hole drilling device which is used for drilling holes on a flask automatically before pouring and is characterized by comprising a rack, a molding flask positioning device, a longitudinal mobile support, a transverse mobile support and a drilling mechanism, wherein the molding flask positioning device is positioned at the upper end of the rack, and the drilling mechanism is connected with the longitudinal mobile support and the transverse mobile support in a matching way. The air hole drilling device has a simple structure, is firm and durable, reduces manpower, improves the production efficiency, reduces cost, and brings certain economic benefit for industrial production.

Description

technical field [0001] The invention relates to the technical field of foundry machinery, in particular to an air hole drilling device for automatic drilling of upper sand boxes. Background technique [0002] In the casting molding automatic line, after the molding of the static pressure molding machine is completed, due to the poor air permeability of the sand tire, the exhaust gas and other gases generated during pouring cannot be discharged, and the castings after pouring will have defects such as pores. The pistol drill does not exhaust the exhaust gas well, which not only wastes a lot of manpower, but also has an unsatisfactory effect. For this reason, need to seek a kind of device to solve this problem. Contents of the invention [0003] In order to solve the problem of automatic drilling of the upper sand box before pouring, the present invention proposes the following technical solutions: [0004] An air hole drilling device is used for automatic drilling of the ...
