Description

The overall oil cylinder plays the role of moving the injection molding
mechanism, and the whole is slender. The back cover and the cylinder barrel are
welded into a whole. Small size oil cylinder, piston rod and piston are welded
as a whole, with high assembly precision, and the front cover is soldered with
bronze guide, which has good wear resistance.

1. Tie rod type, the front and rear covers are fixed by a tie rod. Limited by
the tie rod, it is generally suitable for small oil cylinders. Although the wall
thickness is the thinnest, under the same specification, the external dimensions
will be too large, and the space waste is serious.

2. Bolt type, the front and rear covers and the cylinder barrel are connected
by bolt groups. The required thickness of the cylinder is the largest, and the
raw materials are relatively wasteful. Generally suitable for large
cylinders.

3. Threaded type, the front and rear covers and the cylinder barrel have
large threads, and are connected by threads. The required thickness is smaller
than the bolt type, but it is still thicker, and a large nut is required to
ensure the assembly direction. Generally suitable for large long cylinders

4. Welding type, the back cover and the cylinder are welded into a whole, the
wall thickness of the cylinder is relatively thin, and the whole is relatively
compact. The material cost is not high, but the processing is the most difficult
and the processing cost is the highest.
