1, the choice of seals
The reliability of the hydraulic system depends to a large extent on the design of the hydraulic system seal and the choice of seals. Due to the unreasonable use of the seal structure in the design, the selection of seals does not conform to the specification, and the hydraulic oil is not taken into account in the design. Sealing material type of compatibility, load conditions, limit pressure, working speed, environmental temperature changes.
All of these causes the hydraulic system leakage directly or indirectly to varying degrees. In addition, because the environment of the injection molding machine has dust and impurities, it is necessary to use a suitable dust seal in the design to prevent dust, dirt, etc. from entering the system to destroy the seal and contaminate the oil, thereby causing leakage.
2, other design reasons
The design takes into account that the geometric accuracy and roughness of the moving surface are not comprehensive enough, and the strength check of the joints is not performed in the design, etc., and these all cause leakage in the mechanical work.
