The invention discloses an air hole pricking device. The air hole pricking device comprises two supporting rods arranged symmetrically. A transverse rod is connected between the two supporting rod through a lifting device. An air cylinder is fixedly connected with the lower end of the transverse rod. A piston rod is connected with the output end of the air cylinder. The end, away from the air cylinder, of the piston rod is fixedly connected with a movable plate arranged transversely. A plurality of mounting grooves with openings facing downwards are formed in the side wall of the lower side ofthe movable plate. Steel needles are inserted in the mounting grooves. The movable plate is provided with sliding grooves communicating with the mounting grooves. The inner wall of the side, away from the mounting grooves, of the sliding groove is connected with clamping blocks through springs. The side walls of the steel needles are provided with clamping grooves matched with the clamping blocks. Sliding rods are fixedly connected with the side walls of the clamping blocks. A strip-shaped opening communicating with the sliding groove is formed in the side wall of the lower side of the movable plate. The sliding rods penetrate through the strip-shaped opening. The air hole pricking device is easy, rapid and convenient to dismount and mount and convenient to replace, the working efficiencyis improved, and the application range is wide.
Description
technical field [0001] The invention relates to the technical field of casting, in particular to an air hole piercing device. Background technique [0002] At present, the horizontal static pressure molding line used by foundry enterprises in our country, in the production process, considering the venting problem of the mold cavity during the pouring process, it has become an indispensable link to pierce the air holes of the sand mold. Most foundry companies use manual porosity piercing, which is dangerous and low in efficiency. The steel needles for piercing holes are easily damaged and inconvenient to replace. Therefore, we propose a porosity piercing device to solve these problems. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings of the prior art, such as low efficiency of manual piercing, potential safety hazards, and non-replacement of steel needles, etc., and propose a device for piercing air holes. [0004] In ord...
