Meanwhile, when excessive lubricant is added between the guide rod and the guide sleeve, the second opening of the first through hole on the outer surface of the guide sleeve can be opened for discharging.
According to the guide mechanism of the die casting die, the spiral directions of the spiral groove I on the guide post and the spiral groove II on the guide sleeve are preferably opposite to each other, so that the adhesion uniformity of the lubricant on the outer surface of the guide rod and the inner surface of the guide sleeve in the process that the guide post makes reciprocating linear motion in the guide sleeve can be improved, and the lubrication effect is further improved.
Compared with the prior art, the guide mechanism of the die casting die has the following technical advantages and characteristics:
1. According to the guide mechanism of the die-casting die, the lubricant (lubricating oil) added once can be attached to the outer surface of the guide rod and the inner surface of the guide sleeve for a long time, the reciprocating linear motion of the guide post in the guide sleeve is lubricated for a long time, the friction coefficient of the contact surface of the guide post and the guide sleeve is reduced, the adding period of the lubricant is prolonged, the adding frequency is reduced, the die-casting production efficiency of the die-casting die is finally improved, and the production cost of the die-casting die is reduced.
2. The guide mechanism of the die casting die provided by the utility model has the advantages that the lubrication effect of the lubricant in the guide process is good, the mechanical abrasion in the guide process is relatively less, the guide accuracy of the mechanism is high, and meanwhile, the service life of the guide mechanism is prolonged.
