Description

Technical Field

[0001] The utility model relates to the technical field of oil cylinders, in particular to a stroke-adjustable die-casting oil cylinder. Background Art

[0002] The oil cylinder is also called a hydraulic cylinder. The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] Traditional cylinder stroke adjustment methods often involve complex mechanical structures or electronic control systems, which are cumbersome to operate, and have low adjustment accuracy and efficiency. In addition, when the stroke length of the cylinder needs to be changed, it is usually necessary to replace cylinders of different lengths or perform cumbersome adjustments, which reduces production efficiency. Therefore, a die-casting cylinder with adjustable stroke is proposed. Utility Model Content

[0031] In order to facilitate the adjustment of the extension length of the oil cylinder body 1, an adjustment component 8 is provided, and the adjustment component 8 includes a fixing frame 81, and a first slide groove 86 is provided inside the fixing frame 81. A slide plate 84 is slidably connected to the inner side of the first slide groove 86. When the pull block 82 is pulled to one side, the pull block 82 drives the pull rod 85, the slide plate 84 and the limit rod 88 to move to one side, so that the limit rod 88 leaves the inner side of the limit hole 83, and then the first connecting rod 5 can be pulled to slide inside the second slide groove 89, and one side of the slide plate 84 is fixed. There is a limit rod 88, a pull rod 85 is fixed on the other side of the slide plate 84, and a plurality of limit holes 83 are opened on one side of the first connecting rod 5. The outer side of the limit rod 88 is adapted to the inner side of the limit hole 83, and a spring 87 is sleeved on the outer side of the pull rod 85. The two ends of the spring 87 are respectively connected to the slide plate 84 and the inner side wall of the first slide groove 86, so that the limit hole 83 is located on one side of the limit rod 88, and then the pull block 82 is released. At this time, under the elastic force of the spring 87, the limit rod 88 is pushed to be inserted into the inner side of the limit hole 83;

[0032] A pull block 82 located on the outside of the fixing frame 81 is fixed at one end of the pull rod 85. The pull block 82 is in the shape of a cylinder. One end of the limit rod 88 is inserted into the inner side of the locking groove 810. By inserting the limit rod 88 into the inner side of different limit holes 83, the stroke of the push rod 4 at one end of the cylinder body 1 can be conveniently adjusted. A second slide groove 89 is provided on the inner side of the second connecting rod 6. The outer side of the first connecting rod 5 is slidably connected to the inner side of the second slide groove 89. The inner wall of the second slide groove 89 is provided with a locking groove 810.

One side of the fixing frame 81 is fixed to the outer side of the second connecting rod 6, and the locking groove 810 is located on one side of the limit rod 88.

[0033] Working principle: When the oil cylinder body 1 is in use, the oil supply port 2 and the oil outlet port 3 are connected to the hydraulic station respectively, and then the push rod 4 of the oil cylinder body 1 is controlled to extend or retract through the hydraulic station. During die-casting production, when it is necessary to adjust the push rod 4 of the oil cylinder body 1 to extend at the maximum extension length, it is only necessary to pull the pull block 82 to one side. At this time, the pull block 82 drives the pull rod 85, the slide plate 84 and the limit rod 88 to move to one side, so that the limit rod 88 leaves the inner side of the limit hole 83, and then the first connecting rod 5 can be pulled to slide inside the second slide groove 89, so that the corresponding limit hole 83 is located on one side of the limit rod 88, and then the pull block is released. 82, at this time, under the elastic force of the spring 87, the limit rod 88 is pushed to be inserted into the inner side of the limit hole 83, and one end of the limit rod 88 is inserted into the inner side of the lock groove 810. By inserting the limit rod 88 into different inner sides of the limit holes 83, the stroke of the push rod 4 at one end of the cylinder body 1 can be easily adjusted. By simply operating the pull block 82 and sliding the first connecting rod 5, the stroke of the push rod 4 can be quickly adjusted to adapt to the requirements of different die-casting processes for the length of the push rod 4. The cylinder body 1 can be quickly adjusted to be at the longest stroke and continue to be lengthened, which reduces the time of replacing the cylinder body 1 of different lengths or adjusting the die-casting machine, thereby improving the production efficiency;

[0034] When the connecting head 7 connected to the die-casting machine is worn, it is only necessary to pull the pull block 82 to one side so that the limiting rod 88 leaves the inner side of the limiting hole 83, remove the connecting head 7 and the first connecting rod 5, insert the new first connecting rod 5 into the inner side of the second slide groove 89, and rotate the first connecting rod 5 at the same time so that the limiting hole 83 on the outer side of the first connecting rod 5 is located on one side of the limiting rod 88, and then release the pulling force of the pull block 82. At this time, the new connecting head 7 can be connected to the cylinder body 1. The operation is simple and convenient. By pulling the pull block 82 and rotating the first connecting rod 5, the worn connecting head 7 can be quickly removed and a new one can be installed, which greatly shortens the replacement time and improves the maintenance efficiency. Timely replacement of the worn connecting head 7 can avoid production failures and product quality problems caused by poor connection, thereby ensuring the stability of die-casting production.
