Description

Automatic pouring gate device for piston ring molding line top box Technical Field The invention relates to the technical field of casting production equipment, in particular to an automatic gate tapping device for a piston ring molding line top box. Background The traditional piston ring sand mould modeling adopts a machine modeling mode, a manual loading and unloading sand box mode and a stacking mode. With the development of automation technology, a multi-station automatic molding machine is developed, and a special manipulator is adopted for loading and unloading sand boxes and automatically stacking, so that the production efficiency is improved. However, after molding is completed, the top box still needs to be subjected to gating treatment for the subsequent pouring process. At present, the working procedure is mostly completed by manpower, and specifically comprises the steps of taking down and carrying the top box to a gating station, gating, overturning the top box and placing the top box back into a sand mould stack. The process has the problems of high labor intensity, poor working environment, low efficiency and poor consistency. In the prior art, although the modeling process is automated, the links of pouring gate and overturning top box still depend on manual operation, so that the automation degree and the productivity of the whole production line are restricted. Therefore, a device capable of automatically completing top box gating and overturning is needed, so that the labor intensity of workers is reduced, and the production efficiency and stability are improved. Disclosure of Invention Therefore, the invention aims to provide an automatic gating device for a piston ring molding line top box, which realizes automatic conveying, gating and overturning of the top box, replaces manual operation and improves production efficiency and consistency. The automatic gate device for the top box of the piston ring molding line comprises a gate device arranged beside the molding line and a top box carrying device arranged between the molding line and the gate device in a crossing manner, wherein the top box carrying device is used for carrying the top box on the molding line to the gate device, gate the top box through the gate device, and carrying the top box after gate is turned over back to the molding line.
