Specific implementation mode
The utility model is illustrated with reference to specific embodiment.
As shown in Figure 1 to Figure 3, mode structure after a kind of twice core pulling applied to injection mold includes to be installed in injection molding
The outer end side of the rear mold mold core 1 of the rear pattern plate of mold, rear mold mold core 1 can actively install once core pulling cunning with respect to left and right horizontal
Block 2, twice core pulling sliding block 3.
Further, twice core pulling sliding block 3 away from the surface of rear mold mold core 1 in being provided with the shovel with injection mold respectively
Matched clinoplain 31, perpendicular 32, perpendicular 32 are located at the upper end side of clinoplain 31, twice core pulling sliding block 3
A corresponding core-pulling slide block 2 offer the glide direction along a core-pulling slide block 2 completely through movable mounting hole 33, once
Core-pulling slide block 2 can opposite left and right actively be intercalated in the movable mounting hole 33 of twice core pulling sliding block 3, twice core pulling sliding block 3 in
Jacking block mounting blocks 4 are installed at the outer end opening of movable mounting hole 33, jacking block mounting blocks 4 offer the jacking block run all the way around
Mounting hole 41 can actively be embedded with movable jacking block 5, activity in the jacking block mounting hole 41 of jacking block mounting blocks 4 with respect to left and right horizontal
Jacking block 5 is located at the outer end side of a core-pulling slide block 2 and the inner face of movable jacking block 5 and the outer end face of a core-pulling slide block 2 touch,
The outer end of active positioning block is provided with the jacking block inclined-plane 51 parallel with the clinoplain of twice core pulling sliding block 3 31.
Further, a core-pulling slide block 2 is provided with outside shoulder block 21, and twice core pulling sliding block 3 is in a core-pulling slide block 2
Interior end side be provided with inside shoulder block 34, the spring arranged in horizontal cross is installed between outside shoulder block 21 and inside shoulder block 34
6, the inner end of spring 6 is abutted with inside shoulder block 34, and the outer end of spring 6 is abutted with outside shoulder block 21.
It need to be explained further, jacking block mounting blocks 4 are spirally connected with twice core pulling sliding block 3.
Wherein, to prevent movable jacking block 5 from being exited out of jacking block mounting blocks 4 jacking block mounting hole 41, the utility model uses
Following disconnecting prevention structure designs, specifically：The inner end of movable jacking block 5 is provided with anticreep shoulder block 52.In 5 installation process of movable jacking block
In, movable jacking block 5 is out of interior the jacking block mounting hole 41 for being inserted into jacking block mounting blocks 4 outward, 52 energy of anticreep shoulder block of movable jacking block 5
Enough play the role of blocking limit.
For the twice core pulling sliding block 3 of the utility model, it actively can be installed in injection mold in left and right relatively
Rear pattern plate.During utility model works, when injection mould closing, the shovel of injection mold compresses twice core pulling sliding block
3 clinoplain 31 and the jacking block inclined-plane 51 of movable jacking block 5, at this time spring 6 be in compressive state, the jacking block of movable jacking block 5
Inclined-plane 51 is concordant with the clinoplain 31 of twice core pulling sliding block 3；When injection mold molds, the shovel disengaging of injection mold is secondary
The clinoplain 31 of core-pulling slide block 3, in the process, the side movement outwardly under the elastic force effect of spring 6 of a core-pulling slide block 2
And it is detached from glue part, to realize a core pulling action；During realizing a core pulling action, the shovel of injection mold keep with
The perpendicular 32 of twice core pulling sliding block 3 contacts, and a core-pulling slide block 2 towards outside pushing tow movable jacking block 5 and makes movable top
The jacking block inclined-plane 51 of block 5 stretches out twice core pulling sliding block 3；After the completion of waiting for a core pulling action, injection mold continues die sinking action, when
When the shovel of injection mold is detached from the perpendicular 32 of twice core pulling sliding block 3, since twice core pulling sliding block 3 is no longer injection molding mold
Shovel limit, twice core pulling sliding block 3 can outwardly move relative to rear mold mold core 1, to realize twice core pulling action.
It is emphasized that for the perpendicular 32 of twice core pulling sliding block 3, can ensure in a core pulling action
Start twice core pulling action again after the completion.
Also it is exactly, it, can be by cylinder or electric telescopic rod for the twice core pulling sliding block 3 of the utility model
Structure directly driven.
Based on the above situation, it may be appreciated that by said structure design, the utility model has novel in design, simple in structure, steady
The advantages of determining good reliability, low manufacture cost.
The above content is only the preferred embodiment of the utility model, for those of ordinary skill in the art, according to this reality
With novel thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as
Limitations of the present invention.
