Description

TECHNICAL FIELD

[0001] The utility model relates to a tire mold processing technical field, concretely relates to a kind of EDM cooling circulation system. BACKGROUND

[0002] The main role of tire pattern is to increase the friction between the tire and the road surface to prevent wheel skidding, and the tire tread shape is complex and various. EDM (EDM) can process materials and complex-shaped workpieces that are difficult to cut by conventional cutting methods, and is not affected by material hardness. It is very suitable for processing complex-shaped tire molds. By EDM tire mold, the electrode shape needs to be copied into the shape of the mold (a certain module), and finally copied to the workpiece. The electrode working surface is large, and a large amount of heat is generated during EDM. If not cooled in time, it may cause thermal deformation of the electrode and the mold, increase electrode wear, reduce processing accuracy, and affect the performance and service life of the tire mold. Therefore, the cooling system is very important.

[0003] For example, Chinese patent CN208613942U discloses a cooling oil circulation system of EDM, which comprises a machining table and a cold oil injection assembly installed on the machining table. The cold oil injection assembly comprises an oil collecting groove, an intermediate pump, a separation column, an oil storage tank and a pressure pump. The bottom surface of the machining table is connected with an oil collecting pipe between the oil collecting groove. A filter screen is arranged in the oil collecting groove. The intermediate pump and the bottom of the oil collecting groove are connected with an intermediate liquid inlet pipe. The intermediate pump and the separation column are connected with an intermediate liquid outlet pipe. A separation cavity is arranged in the separation column. One end of the intermediate liquid outlet pipe is inserted into the separation cavity, and the pipe opening is higher than the bottom of the separation cavity. The top of the separation cavity and the oil storage tank are connected with an oil storage pipe. The oil storage tank and the pressure pump inlet are connected in communication. The pressure pump outlet is connected in communication with the cold oil injection assembly.

[0004] However, the technology has the following problems. The solid-liquid separation is achieved by the gravity of solid particles themselves. However, it is difficult to achieve complete separation of solid particles by gravity settling alone. Some small particles may be suspended in the oil layer and cannot sink to the water layer, resulting in residual impurities in the separated liquid and reducing the utilization rate of the cooling liquid.

[0005] Therefore, the utility model designs an EDM cooling circulation system to solve the above problems. UTILITY MODEL CONTENTS
