Automatic core shooter

Abstract

The invention relates to a full-automatic core shooter. The full-automatic core shooter comprises a die and a core shooting device shooting core sand into the die. The die is divided into an upper die body, a middle die body and a lower die body. Buckle mechanisms controlling the middle die body and the lower die body to be opened and closed are arranged on the two opposite side faces of the die. The full-automatic core shooter further comprises a solidifying device, a die stripping device, a moving device, a material receiving device and a PLC control system. The solidifying device comprises a solidifying rack, a blowing mechanism and a die splitting mechanism. The die stripping device comprises a die stripping rack, a lifting mechanism lifting the die, an overturning mechanism overturning the lifted die, and an ejecting mechanism enabling a mold core in the die to be stripped. The moving device is driven by a servo motor, and the die is accurately positioned or horizontally reciprocates at the stations of the core shooting device, the solidifying device and the die striping device. The material receiving device is used for automatically conveying the mold core obtained in the die stripping device. The PLC control system controls drive motors and air cylinders in the core shooting device, the solidifying device, the die stripping device, the moving device and the material receiving device so as to achieve automatic running.

Description

technical field [0001] The invention relates to the field of molding equipment for casting molding, in particular to a fully automatic core shooter for manufacturing cores with cold boxes. Background technique [0002] Core shooters are widely used in the foundry industry and are suitable for both hot and cold core boxes. The working principle of the core shooting machine is to shoot the core sand mixture with liquid or solid thermosetting resin as the binder into the core box mold, and take out the core sand after hardening in the mold to obtain the core. At room temperature, the core-making method in which the sand core is rapidly hardened and formed in the core box by blowing air is called the cold box method. Cold box is a high-efficiency manufacturing process for sand cores. It has the advantages of high efficiency, energy saving, and good working conditions. It has been widely used in foundry production. [0003] At present, most of the existing core shooting machine...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the existing core shooting machines are designed in one piece, and it is difficult to realize complete automation of core shooting, curing, demoulding and other processes; the structural design of the mold makes the mold clamping accuracy of the mold poor after the core is demoulded, which affects the core. Quality; the traditional demoulding process cannot use cores with complex shapes and structures, and the cores are often damaged and cannot be used when demoulding; receiving cores is also manual, so the degree of automation is low, and the demand for manpower is large. high cost
