一种用于两板注塑机的油缸排气结构
摘要：
本实用新型公开了一种用于两板注塑机的油缸排气结构，其特征在于：所述第一空腔与车壁外表面之间设置有第一中空孔道，所述第二空腔与车壁外表面之间设置有第二中空孔道，所述第一中空孔道和第二中空孔道内分别设置有位移感应棒，所述第一中空孔道中的位移感应棒靠近车壁外表面的一侧对应套设有第一单向阀，所述第二中空孔道中的位移感应棒靠近车壁外表面的一侧对应套设有第二单向阀。本实用新型的有益效果是：结构简单，而且能够有效地排除液压油缸中的空气，从而增加油缸的使用寿命。
摘要（英）：

The utility model discloses a hydro -cylinder exhaust structure for two board injection molding machines, its characterized in that: be provided with first cavity pore between first cavity and the vehicle wall surface, be provided with second cavity pore between second cavity and the vehicle wall surface, be provided with displacement response stick in first cavity pore and the second cavity pore respectively, displacement response stick in the first cavity pore is equipped with first check valve near the corresponding cover in one side of vehicle wall surface, displacement response stick in the second cavity pore is equipped with the second check valve near the corresponding cover in one side of vehicle wall surface. The beneficial effects of the utility model are that: simple structure can get rid of the air among the hydraulic cylinder moreover effectively to increase the life of hydro -cylinder.
