Problems solved by technology

Since the automatic air hole drilling machine or air hole piercing machine controlled by PLC can only determine the coordinate position of the air holes through programming, the air holes need to be pierced one by one during the production process. For castings with more air holes (such as engine cylinder blocks), it takes a long time and is seriously restricted. improved production efficiency

Embodiment Construction

[0031] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0032] Such as Figure 1 to Figure 6 As shown, a device for piercing air holes includes a first plate 1, a second plate 2 and a hole piercer. Such as figure 2 The first plate 1 shown is a rectangular thick steel plate, with five first installation holes 11 arranged in the middle of its top surface, and the first installation holes 11 are used to connect and assemble with the cylinder hinge support on the casting molding automatic production line. The four corners of the top surface of the first plate 1 are provided with second mounting holes 12 for cooperating with the guide rods on the casting molding automatic production line. Guides are arranged at the broad sides of the first plate 1, and before the air hole piercing device enters into the hole piercing action, the guides cooperate with the positioning pins on the sand box, so as to achie...

Abstract

The invention discloses an air hole pricking device. According to the device, a first plate is mounted on an oil cylinder of an automatic casting and molding production line through first mounting holes and second mounting holes, and all exhaust holes of a cavity are pricked through at a time by the aid of multiple hole pricking devices assembled on threaded holes in a second plate, so that the hole pricking time is shortened, and the production efficiency is improved. The second plate is detachably arranged below the first plate, so that different second plates can be selected for the air hole pricking device according to different sand molds, and the adaptability of the air hole pricking device is improved; all that is required for hole pricking of the different sand molds is to replace the second plate after the air hole pricking device is mounted on the production line, so that the working efficiency of the whole production line is further improved.

Description

technical field [0001] The invention belongs to parts or accessories of an automatic casting molding production line, 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. Therefore, most foundry companies use several people to hold long-handled needle bars, stand on both sides of the casting line sand box car, and pierce the air holes according to the positions of the air holes produced in the molding process. The above operation method has low production efficiency, poor sand mold quality and potential safety hazards. [0003] In recent years, with the continuous development of the manufacturing industry, the production of casting parts has also increased sharply, so that...
