Description

Technical Field

[0001] The utility model relates to the technical field of mold oil cylinders, in particular to a mold oil cylinder which is convenient to maintain. Background Art

[0002] The oil cylinder generally refers to the hydraulic cylinder, which is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging motion). It has a simple structure and reliable operation, and is widely used in the hydraulic systems of various machines.

[0003] For example, the authorization announcement number "CN217926546U" is named as a mold cylinder that is easy to maintain. Although the annular brush is inserted into the hydraulic rod, the annular brush contacts the surface of the hydraulic rod, the through hole on the arc block is aligned with the threaded hole on the first cylinder head, and the hexagon socket bolt is connected to the threaded hole to limit the annular brush. When the hydraulic rod moves, the dust on the surface of the hydraulic rod is brushed off to prevent the dust from entering the cylinder and causing the cylinder to run poorly, but it still exists. Due to the existing mold cylinder that is easy to maintain, the mold cylinder is installed in the designated position where it needs to work due to the connecting holes at both ends. However, this requires the mold cylinder that is easy to maintain to be fixed somewhere. Only after stopping work and removing the connecting holes and fixed points at both ends can the mold cylinder that is easy to maintain be maintained and inspected. After waiting for the inspection to be completed, the mold cylinder that is easy to maintain will be re-fixed to the original position. Therefore, the maintenance process of the mold cylinder that is easy to maintain will become more laborious.

[0004] At the same time, the existing mold cylinder that is easy to maintain adopts a brush that surrounds the outside of the oil fume rod at the end of the telescopic cylinder to clean up the debris. However, the cylinder is started by the driving force of the hydraulic pressure. The cylinder will often retract and extend up and down during operation. In this way, the end of the brush and the contact part of the cylinder rub frequently, so the brush will be worn out very much. Therefore, it is necessary to frequently replace the brush for cleaning the outside of the cylinder, which increases the cost of using the existing mold cylinder that is easy to maintain.

[0028] Working principle:

[0029] When installing the oil cylinder first, put the fixing sleeve 61 on the top of the oil cylinder barrel 1, then put the mounting seat 62 on the lower end of the oil cylinder barrel 1, pass the side rod 63 at the lower end of the fixing sleeve 61 with the threaded rod 64 through the bottom end of the mounting seat 62, screw the nut 65 to lock it and then complete the installation of the oil cylinder barrel. At this time, install the mounting seat 62 and the fixing barrel 61 at the position where the oil cylinder is needed. When disassembling, just screw the nut 65, remove the lower end of the mounting seat 62, and then inspect the bottom end of the oil cylinder barrel 1. The upper ends of the two sealing rings 66 are movably connected to the lower end of the fixing sleeve 61. The sealing ring 66 is made of rubber material and can fit between the oil cylinder barrel 1 and the mounting seat 62 and the fixing sleeve 61 to improve the sealing performance.

[0030] Then, the rubber material of the close-fitting sheet 84 is used to fit the outer wall of the oil cylinder rod 2 more tightly, and the fixed sleeve 61 surrounds the collar 81 on the outer side of the oil cylinder rod 2. When the oil cylinder rod 2 is retracted, the spring sheet 83, under the support of the limit plate 82, fits the close-fitting sheet 84 on the outer wall of the oil cylinder rod 2. At this time, the dust and debris on the outer side of the oil cylinder rod 2 will be scraped off by the close-fitting sheet 84, and the lubricating oil can be filled in the lubricating cavity 85 through the oil filling hole 86. At this time, the lubricating oil will lubricate the outer wall of the oil cylinder rod 2. When the limit ball 87 is pushed upward by the oil cylinder rod 2, it will push the close-fitting sheet 84 outward, and at this time, the dust on the close-fitting sheet 84 can be swept to the outer side of the collar 81 and will not enter the oil cylinder barrel 1 by chance.

[0031] Finally, the fixing hole 73 can be flipped along the rotating pin 72. At this time, the fixing hole 73 is close to the position where it needs to be installed. The fixing bolts and screws are passed through the fixing holes 73 to fix the cylinder. The sealing gasket 9 is made of rubber material to improve the sealing performance of the end of the cylinder barrel 1. The top of the threaded head 3 is fixedly installed with a connecting head 4, which is connected to the cylinder pusher. The threaded head 3 improves the connection method of the end of the cylinder rod 2.
