Description

A kind of die casting guidance guide pillar structure

Technical field

The utility model relates to technical field of mold, and in particular to a kind of die casting guidance guide pillar structure.

Background technique

Guide pillar structure is guided for existing die casting, guide post abrasion deformation, curved easily occurs in use for mold Frequent stress in stress concentration and use process is also easy to produce at bent, step, so crackle or fracture etc. are existing frequent occurrence at step As, cause guide post reparation is difficult even to scrap, and it is longer to remake the guide post period, it is at high cost, it is very inconvenient to repair replacement.

Utility model content

Purpose of utility model: the utility model aim is to provide a kind of die casting guidance guide pillar structure, solves existing Guidance guide post abrasion deformation, crackle or the problem of fracture frequent occurrence at step.

Technical solution: a kind of die casting of the utility model guides guide pillar structure, including level-one guidance guide post and second level to draw Guide post, one end of the level-one guidance guide post are provided with circular bosses, and second level guidance guide post one end is provided with and circular bosses The circular hole matched.

Further, one end that the level-one guidance guide post is provided with circular bosses is provided with the first internal screw thread in the axial direction Hole, the other end are provided with the second internal thread hole in the axial direction.Level-one guides guide post to guide guide post and guide post step to adopt with second level It is threadedly coupled, finds that damage, disassembly easily, reduce repair cost in use process.

Further, the level-one guidance guide post is provided with guide post step, the guide post step far from one end of circular bosses It is inside provided with first through hole, guide post step passes through first through hole by attachment screw and level-one guides the second internal thread hole of guide post Connection.Level-one guides guide post, using being threadedly coupled, to maintain easily with guide post step.

Further, one end setting of the second level guidance guide post far from circular hole is fluted, between the groove and circular hole It is provided with the second through-hole, the second level guidance guide post passes through the second through-hole by attachment screw and level-one guides in the first of guide post Threaded hole connection.

Further, the circular bosses and circular hole are interference fitted, and ensure that assembly precision and concentricity requirement.

Further, the end face of the second level guidance guide post is provided with circular arc chamfering, can prevent the side of second level guidance guide post Edge collsion damage can reduce stress concentration, reinforce the intensity of second level guidance guide post.

The utility model has the advantages that the utility model compares existing guidance guide pillar structure, split type guidance guide pillar structure is used Design, structure are simple；Using being threadedly coupled between separate structure, guarantee that level-one guidance guide post and second level guidance guide post are linked and packed Precision；Level-one guidance guide post one end is designed to circular bosses, and second level guidance guide post one end is designed to circular hole, being installed as between the two Interference fit ensure that assembly precision and concentricity requirement well；And any structure damages in use process, dismantles very square Just, can individually a certain structure be replaced and is repaired, reduce maintenance cost.

Fig. 2 is that level-one guides guide pillar structure schematic diagram；

Fig. 3 is that second level guides guide pillar structure schematic diagram；

Fig. 4 is guide post step structure schematic diagram.

Specific embodiment

The utility model is described further with reference to the accompanying drawings and examples:

As shown in Figures 1 to 4, a kind of die casting guidance guide pillar structure of the utility model, including level-one guidance guide post 1, Second level guidance guide post 2 and guide post step 3, the guidance guide pillar structure adopt a split structure design, and structure is simple.Wherein level-one is drawn One end of guide post 1 is provided with circular bosses 11, and second level guidance 2 one end of guide post is provided with the circular hole 21 matched with circular bosses 11, Circular bosses 11 and circular hole 21 between the two be installed as being interference fitted, magnitude of interference is designed as 0.01~0.03mm according to its size Between, it ensure that assembly precision and concentricity requirement well.

One end that level-one guidance guide post 1 is provided with circular bosses 11 is provided with the first internal thread hole 12, second level in the axial direction It guides guide post 2 to be arranged fluted 22 far from one end of circular hole 21, the second through-hole 23, second level is provided between groove 22 and circular hole 21 Guidance guide post 2 passes through the second through-hole 23 by attachment screw and guides the first internal thread hole 12 of guide post 1 to connect with level-one；Level-one is drawn 1 other end of guide post is provided with the second internal thread hole 13 in the axial direction, is provided with first through hole 31, guide post in guide post step 3 Step 3 passes through first through hole 31 by attachment screw and guides the second internal thread hole 13 of guide post 1 to connect with level-one.Second level is drawn simultaneously The end face of guide post 2 is provided with circular arc chamfering 24, can prevent the peripheral collision damage of second level guidance guide post 2, can reduce stress It concentrates, reinforces the intensity of second level guidance guide post 2.

Level-one guides between guide post 1, second level guidance guide post 2 and guide post step 3 using being threadedly coupled, and guarantees that level-one is led The precision that column 1 and second level guidance guide post 2 are linked and packed, and any structure damages in use process, and disassembly easily, can be independent A certain structure is replaced and repaired, reduces maintenance cost, and service life is got back large increase.
