Specific embodiment
Technical solutions of the utility model are further described below by embodiment:
The utility model provides a kind of assembly and disassembling type guide-post of die-set of self-lubricating, as shown in Figure 1, guide-post of die-set includes: guide rod
1, ball sleeve 2, casing 3, spring 4, briquetting 5, limited block 6, upper chamber 7 and lower oil chamber 8, guide rod 1 are inserted into ball sleeve 2, ball
In 2 insertion casings 3 of set, i.e. ball sleeve 2 positioned at guide rod 1 and casing 3 between, the circular guide rod 1 of spring 4 and with 2 face of ball sleeve,
Briquetting 5 is fixed on the lower end of guide rod 1, and limited block 6 is fixed on the upper end of guide rod 1, upper chamber 7 be located at ball sleeve 2 and limited block 6 it
Between, lower oil chamber 8 is between ball sleeve 2 and spring 4.Upper chamber 7 and lower oil chamber 8 are all formed by flexible material, such as: rubber material
Material.
Guide rod 1 is fixed on lower mold by briquetting 5, and casing 3 is fixed on the upper mold, and casing 3 can cover 2 with counter ball
It moves, so that upper mold relative lower dies be allowed to move.Wherein, spring 4 is in 3 moving process of casing by ball sleeve
2 maintain original position, limit ball sleeve 2 in lower section；When casing 3 is by downward impact, spring 4 can also be in guide rod
Buffer function is played between 1 and ball sleeve 2, avoids guide rod 1 and ball sleeve 2 that rigid contact occurs.Limited block 6 limits rolling above
The moving range of bead sleeve 2.Upper chamber 7 is stored with lubricating oil, and when casing 3 moves up, ball sleeve 2 also accordingly occurs to moving up
Dynamic trend and upper chamber 7 is squeezed, so that the lubricating oil of upper chamber 7 be squeezed out, flow on ball sleeve 2；Lower oil chamber 8 receives rolling
Lubricating oil in bead sleeve 2, when casing 3 moves down, the trend and extruding that ball sleeve 2 also accordingly moves down are lower oily
Room 8, the lubricating oil in lower oil chamber 8 are extruded, are flow on ball sleeve 2 again, achieve the effect that lubricating oil is recycled.
As shown in Fig. 2, guide rod 1 includes leader 11, position portion 12 and support ring 13, leader 11 is from support
The upper surface of ring 13 extends toward the upper end of guide rod 1, and position portion 12 extends from the lower surface of support ring 13 toward the lower end of guide rod 1.
Position portion 12 and briquetting 5, which are formed, to be fixed, and leader 11 is inserted into ball sleeve 2 and is formed with limited block 6 and fixed, spring 4
Between support ring 13 and ball sleeve 2.
As shown in figure 3, ball sleeve 2 includes: retainer 21 and multiple balls 22, the cylindrical shape of retainer 21, multiple rollings
Pearl 22 is in the side wall of retainer 21.The leader 11 of guide rod 1 is inserted into retainer 21, and retainer 21 is inserted into casing 3,
Ball 22 is contacted with casing 3.
Specifically, as shown in figure 4, retainer 21 has multiple ball holes 211 and multiple oil circuits 212, oil circuit 212 and ball
Hole 211 is connected to, and oil circuit 212 extends to lower end from the upper end of retainer 21, and ball 22 is located in ball hole 211.More specifically, such as
Shown in Fig. 5, the middle part of ball hole 211 has accommodating portion 2111, and outside and inside all have restricted portion 2112, accommodating portion
2111 diameter is greater than the diameter of restricted portion 2112, and oil circuit 212 is connected to accommodating portion 2111.When lubricating oil flows into receiving portion
After dividing in 2111, restricted portion 2112 can be maintained lubricating oil in accommodating portion 2111, guarantee its lubricant effect.
As shown in fig. 6, upper chamber 7 has reservoir portion 71, one end of reservoir portion 71 is sealed, and the other end has multiple companies
The communication port 72 of port 72, upper chamber 7 is arranged towards ball sleeve 2.Specifically, the communication port 72 of upper chamber 7 and retainer 21
212 face of oil circuit (is aligned with the upper end of oil circuit 212).The structure of lower oil chamber 8 is identical as upper chamber 7, and details are not described herein,
The communication port of lower oil chamber 8 also towards ball sleeve 2 be arranged, and also with 212 face of oil circuit of retainer 21 (i.e. with oil circuit 212
Lower end alignment).
As it can be seen that the guide-post of die-set with above structure, not only may be implemented the function of self-lubricating, improve abrasion resistance properties with
And cooperation precision, and since upper chamber is arranged between ball sleeve and limited block, it does not need need not with casing movement yet
It is exposed to outside, efficiently solves the problems, such as that oil pressure is unstable and is easy to happen collision.
