Abstract
The invention discloses a self-lubricating centre plate guide mechanism for mold bases. The self-lubricating centre plate guide mechanism comprises a fixed bottom plate, a guide column and a guide sleeve; a plurality of annular grooves are formed in the outer periphery of the guide column; solid lubricants are embedded into the annular grooves and are made of graphite; the guide sleeve is made of high-strength brass. The self-lubricating centre plate guide mechanism for the mold bases is simple in structure and reasonable in design and is a high-performance lubrication product with the graphite embedded into the guide column on the basis of the guide column made of high-strength brass. In the use process, the guide column enables the solid lubricants to rub against the mold bases through the friction heat, the excellent condition of both oil lubrication and powder lubrication is formed, the centre plate guide mechanism is protected against abrasion, the solid lubrication property is permanent, the hardness and the abrasive resistance of the centre plate guide mechanism are effectively improved, and the service life of the centre plate guide mechanism is greatly prolonged.
Description
Technical field
The present invention relates to a kind of mold base parts, particularly relate to mold base with from profit ejector retainner plate guiding mechanism.
Background technology
Along with improving constantly of technology, the fast development of plastic cement products industry, the diversification structure of all kinds of plastic cement parts becomes increasingly complex, quality requirements is the strictest, the highest to plastic cement products industry requirement, competition is the fiercest, how to ensure that similar plastic cement products occurs without exception, the production cycle that maximized guarantee Product processing is effective, stable in process of production.Ejector pin mechanism is an important accessory of injection mold, used by it is main it is, it is used in injection mold, product is separated from mould, and play the firm effect of mold base, ejector pin mechanism moves back and forth, abrasion easily occur, motion is not smooth, and then causes thimble scratching products, reduce the yield rate of product, cost of idleness.Wherein, pumping of ejector retainner plate guides mainly by ejector retainner plate lead, if lead is stuck in process of production, then cannot normally produce, it is therefore desirable to design a kind of band from the ejector retainner plate guiding mechanism moistening effect, it is ensured that ejector retainner plate pumps smoothness.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose the good mold base of a kind of hardness high-wearing feature with from profit ejector retainner plate guiding mechanism.
The technical solution of the present invention is achieved in that a kind of mold base profit ejector retainner plate guiding mechanism certainly, including fixing base plate, lead and guide pin bushing；Multiple annular groove is offered on the excircle of described lead；Solid lubricant inlaid in described annular groove.
Preferably, described annular groove has 3, is evenly distributed on the excircle of lead.
Preferably, described kollag is graphite.
Preferably, the material of described lead is high-tensile strength pyrite.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The mold base of the present invention is with from profit ejector retainner plate guiding mechanism; its simple in construction; reasonable in design; it is on the basis of the lead of high-tensile strength pyrite; lead is inlayed the high-performance lubrication product of graphite; in use; lead makes kollag and mold base friction by frictional heat; form oil, powder and deposit the excellent condition of lubrication; both ejector retainner plate guiding mechanism had been protected not wear and tear; make again solid lubrication characteristic eternal, be effectively increased hardness and the wearability of ejector retainner plate guiding mechanism, substantially prolongs service life.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the present invention.
Wherein: 1, fixing base plate；2, lead；3, guide pin bushing；4, annular groove.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The mold base of the present invention is with moistening ejector pin mechanism, as shown in Figure 1, including fixing base plate 1, lead 2 and guide pin bushing 3；Multiple annular groove 4 is offered on the excircle of described lead 2；Solid lubricant inlaid in described annular groove 4；Described kollag is graphite；The material of described lead 2 is high-tensile strength pyrite.
Further instruction, described annular groove has 3, is evenly distributed on the excircle of lead.
The mold base of the present invention is with from profit ejector retainner plate guiding mechanism; its simple in construction; reasonable in design; it is on the basis of the lead of high-tensile strength pyrite; lead is inlayed the high-performance lubrication product of graphite; in use; lead makes kollag and mold base friction by frictional heat; form oil, powder and deposit the excellent condition of lubrication; both ejector retainner plate guiding mechanism had been protected not wear and tear; make again solid lubrication characteristic eternal, be effectively increased hardness and the wearability of ejector retainner plate guiding mechanism, substantially prolongs service life.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
