With the development of various mechanical processes, porous die castings, such as various lock cylinders, have become essential mechanical workpieces in daily life. For the lock cylinder, the porous part of the die casting (i.e. the direction of the spring hole is perpendicular to the direction of the key hole, which is the mechanism movable groove to identify the key tooth shape) is an important part of the lock cylinder. Now, in the mechanical process, the spring hole is mostly generated through the row structure. The row position refers to the mechanical movable part pulled from the die casting in advance before the separation of the moving die and the fixed die, The moving direction has a component perpendicular to the moving mode and the fixed mode. The design of row position plays a vital role in the quality of lock cylinder. Generally, the thickness of shrapnel hole is less than 1mm. It is a very small movable mechanism in the whole die, so it is easy to break and wear, and it is difficult to repair. Usually, in order to solve this problem, it is often necessary to calibrate the mold and add lubricating oil regularly, but this will often delay the construction period, and it is easy to damage the whole set of expensive mold due to the misoperation of workers. To sum up, the row structure of the existing die-casting die obviously has inconvenience and defects in practical use, so it is necessary to improve it.

In view of the above defects, the purpose of the utility model is to provide a row position structure of the die-casting die, which adopts an inclined design for the clamping part of the row position structure, effectively reduces the wear of the row position and the die, prolongs the service life of the die and reduces the maintenance cost of the die. In order to achieve the above purpose, the utility model provides a row position structure of a die casting die, which is applied to a lock cylinder. The row position structure includes at least a first row position and a second row position, the first row position includes at least a first clamping structure, and the second row position includes at least a second clamping structure corresponding to the first clamping structure, The first clamping structure and the second clamping structure are arranged obliquely, and both the first clamping structure and the second clamping structure include at least one obtuse angle structure. According to the row position structure of the die casting die of the utility model, the first row position includes eight first clamping structures, and the second row position includes eight second clamping structures corresponding to the first clamping structure. According to the row position structure of the die casting die of the utility model, the first row position and the second row position run through the die casting, and the first row position and the second row position are closed in a mutually embedded manner. Through the inclined design of the clamping positions of the two rows of the die-casting die, each clamping structure of the row includes at least one obtuse angle. Therefore, when the first row and the second row are clamping, the wear of the row and the die can be effectively reduced, the service life of the die can be prolonged and the maintenance cost of the die can be reduced.
