Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines and die-casting machines, in particular to an oil pipe joint. Background Art

[0002] High-pressure oil hoses in injection molding and die-casting machines are key components of their hydraulic systems. These hoses are primarily responsible for delivering high-pressure hydraulic oil to power various operations within the machines, such as mold opening and closing, ejection and retraction, and injection and ejection.

[0003] In most cases, one end of the high-pressure rubber oil pipe moves back and forth repeatedly, while the other end, as a fixed fulcrum, basically does not move. Since the fulcrum oil pipe joint of the high-pressure rubber oil pipe is fixed, the high-pressure rubber oil pipe near the fulcrum joint is repeatedly damaged, which can easily cause fatigue cracking and leakage.

[0004] Therefore, it is necessary to further explore and practice the above technical issues. Utility Model Content

[0010] In the above technical solution, the first bearing and the second bearing are preferably tapered bearings to reduce the axial and radial loads borne by the oil inlet pipe and the oil return pipe when they rotate.

[0011] Furthermore, an oil inlet channel and an oil return channel are provided inside the base, the oil inlet pipe is connected to the oil inlet channel, and the oil return pipe is connected to the oil return channel.

[0012] Furthermore, a first bearing retaining ring is provided at the bottom of the oil inlet pipe, and the first bearing is provided on the top of the first bearing retaining ring.

[0013] In the above technical solution, the first bearing retaining ring confines the first bearing within the first bearing end cover.

[0014] Furthermore, a second bearing retaining ring is provided at the bottom of the oil return pipe, and the second bearing is provided at the bottom of the second bearing retaining ring.

[0015] In the above technical solution, the second bearing retaining ring confines the second bearing within the base.

[0016] Furthermore, a cavity is provided inside the first bearing end cover, and the outer wall of the first bearing is connected to the inner wall of the cavity.

[0017] Furthermore, the base is provided with a groove, and the inner wall of the groove is connected to the outer wall of the second bearing.

[0018] Furthermore, a first sealing area is provided between the first bearing end cover and the base.

[0019] In the above technical solution, the first sealing area is provided to prevent the oil in the oil inlet pipe from overflowing.

[0020] Furthermore, a second sealing area is provided between the second bearing end cover and the base.

[0021] In the above technical solution, the second sealing area is provided to prevent the oil in the oil return pipe from overflowing.

[0022] Furthermore, the parameters of the first bearing and the second bearing are consistent.

[0023] In the above technical solution, after the diameters of the first bearing and the second bearing are set to be equal, the positions of the oil inlet pipe and the oil return pipe can be exchanged according to actual conditions.

[0024] The basic principle of this utility model:

[0025] By arranging a first bearing on the oil inlet pipe and a second bearing on the oil return pipe, the oil inlet pipe and the oil return pipe can rotate, and a first sealing area is arranged at the bottom of the first bearing end cover and a second sealing area is arranged at the bottom of the second bearing end cover, so that the oil inlet pipe and the oil return pipe will not leak oil during use.

[0026] (3) Beneficial effects

[0027] Compared with the prior art, the technical solution of the utility model has the following advantages:

[0028] (1) The utility model provides an oil pipe joint, in which a rotating part is provided in the oil inlet pipe and the oil return pipe, so that the oil pipe joint at the fixed fulcrum of the high-pressure rubber oil pipe becomes rotatable. When the other end of the high-pressure rubber oil pipe moves back and forth repeatedly, it plays a role in protecting the oil pipe near the fixed fulcrum of the high-pressure rubber oil pipe from fatigue damage.

[0029] (2) The utility model provides an oil pipe joint, in which the parameters of the first bearing and the second bearing are set to be consistent, and the positions of the oil inlet pipe and the oil return pipe can be replaced according to actual conditions. BRIEF DESCRIPTION OF THE DRAWINGS
