IUI main oil seal oil cylinder sealing element and machining process thereof

The IUI main oil seal oil cylinder sealing element comprises a sealing element body, an inner lip, an outer lip, an oil discharging groove, an outer root, an inner root and a pressure groove, and the machining technology comprises the steps that firstly, raw materials are selected; 2, mixing the raw materials; step 3, injection molding; step 4, trimming and chamfering; step 5, checking and packaging; an inner lip is arranged on the inner wall of the top end of the sealing element body, the chamfer angle of the inner lip is 30 degrees, a pressure groove is formed in the outer wall of the top end of the sealing element body, and the outer side of the pressure groove is higher than the inner side of the pressure groove. The compression resistance of the product is improved; by increasing the height difference and the gap between the inner lip and the outer lip, a product can be sealed in a more hostile environment; by enlarging and deepening the pressure grooves and increasing the supporting faces of the inner r
