Description
Technical field
The utility model is related to precision die apparatus field more particularly to a kind of Precise die guide pillars.
Background technology
Mold is known as the title of " mother of industry ", in the industrial production, using mold, the moulding material by changing
Physical state realizes the processing of article shape.Mold includes two components of dynamic model and cover half, and the two is partable, the phase of the two
Mutually movement realizes that mold is precision instrument, complex-shaped, formed in mould quality, not only right by the effect of multiple guide posts
Intensity, rigidity, case hardness, surface roughness and the machining accuracy of mold body structure have higher requirement, equally to it
The quality and degree of cooperation of outer guiding post have very high requirement.Guide pillar structure in existing precision die is generally simple, processing essence
Degree is inadequate, and not wear-resisting, the replacement cycle is short, and is oriented to not accurate enough.
Utility model content
It is not accurate wear-resisting enough in order to solve guide post in the prior art, the shortcomings that not accurate enough is oriented to, the utility model provides
A kind of Precise die guide pillar.
Technical solution is used by the utility model solves its technical problem：A kind of Precise die guide pillar, including gland,
Spring, guide post, spin bushing and guide sleeve, it is described to be embedded with bearing embedded with evenly arranged bearing steel spin in the spin bushing
The bushing of steel spin is installed in guide sleeve, and the guide post is cylinder, and one end is equipped with the gland, and the guide post is installed on rolling
It in ball bushing, can be movable relatively, the spring is socketed on guide post.
A kind of above-mentioned Precise die guide pillar, the material of the guide pillars and bushes is bearing steel SUJ2, and the guide post uses
Vacuum heat, the guide sleeve use fully hard heat treatment.
A kind of above-mentioned Precise die guide pillar, the available material of spin bushing have copper sheathing, aluminium alloy, special close modeling
Glue.
A kind of above-mentioned Precise die guide pillar, the spring are socketed on guide post, and one end is connected to the lower face of gland,
The other end is connected to the upper surface of spin bushing.
A kind of above-mentioned Precise die guide pillar, the guide post are fixed on moving platen.
A kind of above-mentioned Precise die guide pillar, the guide sleeve are fixed in quiet template.
The beneficial effects of the utility model are a kind of Precise die guide pillars of the utility model, and work is processed by lathe, grinding machine
Skill, guide post use vacuum heat, and guide sleeve uses fully hard heat treatment, and product hardness is high, and performance is more stable more resistant, the spring
Elasticity is good, is unlikely to deform, stability is good, and spin bushing is inlaid with bearing steel spin, durable not easily to fall off；The guide post and guide sleeve
Between cooperation stablize, be oriented to that accurate, affiliated precision die working efficiency is high, and the up-to-standard rate of shaped article is high.
Description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the utility model appearance diagram；
Fig. 2 is the utility model internal structure schematic diagram.
1-gland in figure, 2-spring, 3-guide post, 4-spin bushing, 5-bearing steel spin, 6-guide sleeve.
Specific embodiment
It is below in conjunction with the accompanying drawings and specific real for those skilled in the art is made to be better understood from the technical solution of the utility model
Mode is applied to elaborate to the utility model.
A kind of Precise die guide pillar including gland 1, spring 2, guide post 3, spin bushing 4 and guide sleeve 6, the guide post 3 and is led
The material of set 6 is bearing steel SUJ2, and the guide post 3 uses vacuum heat, and the guide sleeve 6 uses fully hard heat treatment, the rolling
Ball bushing 4 is copper sheathing, and evenly arranged bearing steel spin 5, the lining embedded with bearing steel spin 5 are inlaid on the bushing 4
Set 4 is installed in guide sleeve 6, and the guide post 3 is cylinder, and one end is equipped with the gland 1, and the guide post 3 is installed on spin lining
In set 4, it can be movable relatively, the spring 2 is socketed on guide post 3, and one end is connected to the lower face of gland 1, and the other end is connected to
The upper surface of spin bushing 4.
During utility model works, the guide post 3 is fixed on moving platen, and the guide sleeve 6 is fixed in quiet template, dynamic model
When plate is pressed with quiet template, guide post 3 is mutually moved with guide sleeve 6, and spring 2 compresses, when closing up, blank injection mold cavity forming,
After part cooling cooling, moving platen and quiet template separate, and 2 length of spring is restored, and take out product, and the longevity is used for raising spring 2
Life, when moving platen and quiet template are closed up, the actual compression stroke of spring 2 is the half of spring compressible amount.
Above example is only the exemplary embodiment of the utility model, is not used in limitation the utility model, this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be in the essence and protection domain of the utility model
It is interior, various modifications or equivalent replacements are made to the utility model, this modification or equivalent replacement also should be regarded as falling new in this practicality
In the protection domain of type.
