Abstract
The utility model is related to a kind of safe ejector pin mechanism, more particularly to the safe ejector pin mechanism that a kind of anti-limited slip block bumps against with thimble.Including mould bases body, the bottom of described mould bases body is provided with ejector retainner plate, sliding block is provided with the upper end of described mould bases body, described sliding block is distributed with Angle Pin fixed block in shape is connected, Angle Pin is provided with described Angle Pin fixed block, described sliding block carries out displacement with the displacement of Angle Pin, and the limited block touched in activity with sliding block is provided with described mould bases body.A kind of anti-limited slip block is compact with the safe thimble mechanism structure that thimble bumps against, and improves assembly precision, lifts operating efficiency, improves product percent of pass.
Description
Technical field
The utility model is related to a kind of safe ejector pin mechanism, more particularly to the safety roof that a kind of anti-limited slip block bumps against with thimble
Pin mechanism.
Background technology
When mould or forming machine occur abnormal in currently available technology, sliding block can bump against with thimble, so as to cause mould
Have reduction life-span and the influence ejection effect of service life.
Chinese patent 201510488944.2, discloses a kind of ejector pin mechanism of injection mold, including location-plate, drive mechanism
And flexible thimble, drive mechanism and flexible thimble be installed on location-plate, and wherein drive mechanism is located at location-plate lower surface, stretches
Contracting thimble end is hinged by ratchet mechanism with location-plate upper surface, and at least two, flexible thimble is simultaneously equal around location-plate center line
Cloth, the thimble that stretches includes positioning sleeve, expansion link and connection cushion block, and wherein expansion link end is embedded in positioning sleeve, and and driving machine
Structure is connected, and expansion link top connects with cushion block lower surface is connected, and is slided by bindiny mechanism between expansion link top and contiguous block
Connection, connection cushion block upper surface sets elastic cushion block.This structure is relative complex, and using effect is not obvious.
The content of the invention
The utility model is mainly solution the deficiencies in the prior art, there is provided a kind of compact conformation, it is adaptable to need
The mould ejected using thimble, a kind of anti-limited slip block of the stability that raising is used and the safe ejector pin mechanism of thimble collision.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
The safe ejector pin mechanism that a kind of anti-limited slip block bumps against with thimble, including mould bases body, the bottom of described mould bases body sets
There is an ejector retainner plate, be provided with sliding block in the upper end of described mould bases body, described sliding block and Angle Pin fixed block are in connecting shape distribution, institute
Angle Pin is provided with the Angle Pin fixed block stated, described sliding block carries out displacement with the displacement of Angle Pin, in described mould bases body
It is provided with the limited block touched in activity with sliding block；
Thimble and safe thimble are provided with described ejector retainner plate, described thimble extends upwardly to the bottom of sliding block, described
Sliding block in be provided with emptiness avoiding hole, described safe thimble overlaps with emptiness avoiding hole in displacement.
Preferably, described limited block is bolted with mould bases body.
Used when mainly having ejection below sliding block, mould can be prevented effectively from or sliding block and thimble during exception occurs in forming machine
Bump against, so as to improve the stability of mould, reducing burn failure increases the risk of maintenance cost and influence product friendship phase.
Sliding block：The profiled part of product.Thimble:The ejector member of product, for the effect of product ejection.Safe thimble:
The effect that protection thimble bumps against with sliding block.Ejector retainner plate：Fixed thimble, for the effect of product ejection.
Limited block：Limit the motion of sliding block.Angle Pin：Drive the effect of sliding block.Angle Pin fixed block：Fixed Angle Pin
Effect.
Operation principle：
During ejection:When sliding block moves to limited block under Angle Pin driving, when safe thimble overlaps with the emptiness avoiding hole of sliding block,
Ejector retainner plate could upwards move completion ejection, if the abnormal sliding block of mould appearance does not move to limited block, safe thimble is in sliding block
Lower section, ejector retainner plate cannot upwards move completion ejection, and thimble can be avoided to bump against with sliding block.
During matched moulds:When ejector retainner plate falls back on, safe thimble end face just can be flat with sliding block die joint, and sliding block could be in Angle Pin
If driving under travel forward moulds when abnormal ejector retainner plate occur and not falling back on, in sliding block emptiness avoiding hole, mould will for safe thimble
Cannot matched moulds, it is to avoid sliding block bumps against with thimble.
Therefore, the safe ejector pin mechanism that a kind of anti-limited slip block of the present utility model bumps against with thimble, compact conformation improves dress
With precision, operating efficiency is lifted, improve product percent of pass.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation when the utility model is ejected；
Structural representation when Fig. 3 is the utility model matched moulds.
Specific embodiment
