Description
Technical field
The utility model relates to a kind of retainer injection mold mould-locking structure, specifically to a kind of cylindrical roller engineering
Plastic cage injection mold mould-locking structure, belongs to Injection Mold Design field.
Background technique
Injection mold structure has very crucial influence to the quality of injection-molded item, especially for engineering plastics cage
For, it since retainer generally uses glass-fiber-reinforced polyamide material to manufacture, is influenced by material processing characteristics, injection molding adds
The requirement of work technique is very high, just very high to the Structural Design Requirement of retainer injection mold accordingly.According to cylinder roller bearing work
The design feature of engineering plastics retainer, injection mold must use sideslip block structure when forming retainer fenestra, then breakking away
The locking mechanism design of block is just extremely important.Currently, side slide locking generally uses inclined guide pillar, the at this moment effect of inclined guide pillar is not only
It is that driving sliding block is moved forward and backward, but also promising sliding block provides coupling mechanism force, guarantees sliding block when plastic melt high pressure enters type chamber
Stationary effect.Although this mould-locking structure is simple, often led to the problem of in production process, main as follows:
1, mold processing and adjustment maintenance are difficult.When mold clamping in place when, sliding block must advance to position, and inclined guide pillar must be same
When and the guiding hole wall of sliding block be tightly close to.This is very high to the cooperation required precision between mould parts, so mold is processed
The requirement of precision be accordingly also it is very high, be extremely difficult to, and be difficult to adjust maintenance.
2, retainer product quality is difficult to ensure.When retainer injection molding, plastic melt is full of mold with high speed and high pressure
Type chamber, mould parts bear the very high pressure from melt, and inclined guide pillar is difficult to complete locking sliding block, sliding block is caused to retract, that
It just will appear burr on the inside of each fenestra surrounding of retainer, influence product quality.
3, mold failure rate is high.Since the melt high pressure in mold cavity acts on inclined guide pillar, and the intensity of inclined guide pillar
It is limited, it is easy to lead to inclined guide pillar fatigue deformation, or even inclined guide pillar occurs often and fractures situation.In addition, inclined guide pillar is led with sliding block
To hole fit clearance very little, phenomenon is pulled frequent occurrence.
Summary of the invention
In view of the problems existing in the prior art, the purpose of the utility model is to provide a kind of holdings of cylindrical roller engineering plastics
Frame injection mold mould-locking structure is easily guaranteed that mold machining accuracy, adjusts easy to maintenance, not only can guarantee product quality, but also energy
Guarantee die quality and service life, and mold can be made reliable for operation in process of production, stable.
To achieve the goals above, technical solution used by the utility model is a kind of cylindrical roller engineering plastics holding
Frame injection mold mould-locking structure comprising: cover half part and dynamic model part；Closing piece is equipped in the cover half part, described is dynamic
Sliding block is equipped in mould part, the closing piece of cover half part and the sliding block of dynamic model part are combined together；
The cover half part further include: solid plate, soket head cap screw and inclined guide pillar, solid plate and closing piece cooperate, described interior
Closing piece is connect fastening with solid plate by hex screw, and the inclined guide pillar is connect with closing piece；
The dynamic model part further include: moving template, wear plate, limit spring, spring supporting bar, wear plate and sliding block connect
It connects, the limit spring is assemblied in the limit hole of sliding block, and the spring supporting bar is assemblied in spring bores, the moving template
Cooperate with sliding block；
The utility model has the beneficial effects that
1, increase closing piece keeps slider locking reliable and stable by closing piece locking sliding block, and sliding block rollback phenomenon will not occur,
Prevent the appearance of retainer burr, it is ensured that product quality.
2, inclined guide pillar does not play the role of locking sliding block, is served only for driving sliding block and is moved forward and backward, inclined guide pillar is made to be not subject to type
The high pressure of intracavitary melt, mold are not in pull, and inclined guide pillar will not be broken, and eliminate mold failure, keep mold stable.
3, increase wear plate, not only improve die quality and service life, but also by the thickness of grinding wear plate, it can be with
Mold mode locking amount is adjusted, making mold, die-closed position and slider locking position are accurate simultaneously in place up and down, become adjustment maintenance and fabrication
Be easy to, mold machining accuracy is easily guaranteed that.

Specific embodiment
In order to further appreciate that the cylindrical roller engineering plastics cage injection mold mould-locking structure, be described with reference to the drawings as
Under:
A kind of cylindrical roller engineering plastics cage injection mold mould-locking structure comprising: cover half part and dynamic model part；
It is equipped with closing piece 3 in the cover half part, sliding block 6, closing piece 3 and the dynamic model part of cover half part are equipped in the dynamic model part
Sliding block 6 is combined together；
The cover half part further include: solid plate 1, soket head cap screw 2 and inclined guide pillar 4, solid plate 1 and closing piece 3 cooperate, institute
It states soket head cap screw 2 and closing piece 3 is connect fastening with solid plate 1, the inclined guide pillar is connect with 4 closing pieces 3；
The dynamic model part further include: moving template 7, wear plate 5, limit spring 8, spring supporting bar, wear plate 5 and sliding block
6 connections, the limit spring 8 are assemblied in the limit hole of sliding block 6, and the spring supporting bar is assemblied in spring bores, described
Moving template 7 and sliding block 6 cooperate；
When mold clamping, cover half part is generally in stationary state, and dynamic model part is mobile to cover half part direction, when oblique
When 4 front end of guide post enters sliding block 6, just drives sliding block 6 mobile to (center position) in front of mold along 7 surface of moving template, advance
While in place, closing piece 3 is contacted with wear plate 5, and sliding block 6 is locked.At this point, limit spring 8 is in compressive state.When mold is opened
When mould, dynamic model part leaves cover half part, and closing piece 3 is separated with wear plate 5, and inclined guide pillar 4 drives sliding block 6 along 7 surface of moving template
Rearward (leaving center position) is mobile, deviates from the leading portion of sliding block 6 from retainer fenestra, meanwhile, limit spring 8 stretches.
When inclined guide pillar 4 is detached from sliding block 6, sliding block 6 is retreated in place, and by limit spring 8 and external stop screw limitation positioning.
