Description
Technical field
The present invention relates to a kind of injection mold, more particularly, to a kind of inner core pulling structure of injection mold.
Background technology
Injection mold is a kind of instrument for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Instrument.Injection molding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to melt heated
Plastics by injection machine high pressure inject die cavity, after cooling and solidifying, obtain formed products.
Inner core pulling structure is the conventional structure of injection mold.It is existing at present big for the inner core pulling structure on injection mold
Combined more by more parts, have the shortcomings that complicated, production cost is high and stable and reliable operation is poor.
The content of the invention
It is an object of the invention to provide a kind of inner core pulling structure of injection mold, its have simple in construction, cost low and
The characteristics of stable and reliable operation, to solve the above mentioned problem existed in the prior art for the inner core pulling structure of injection mold.
For up to this purpose, the present invention uses following technical scheme：
A kind of inner core pulling structure of injection mold, it includes sliding block, two tapered wedges, take-up housing and wearing plate, wherein, institute
Two tapered wedges can be slidably provided with relatively by dovetail groove by stating one end both sides of sliding block, and the sliding block and two tapered wedges are set
It is placed in the take-up housing, is linked between the take-up housing and the sliding block by limit assembly, the bottom of described two tapered wedges
Portion extends downwardly limited location boss, coordinates the positive stop lug boss in the stopper slot that two " L " types are offered on the wearing plate, institute
State positive stop lug boss to be arranged in the stopper slot, the take-up housing can be movably arranged on the wearing plate.
Especially, the limit assembly includes the axis hole that correspondence is opened on the sliding block and take-up housing, both axis holes
It is interior to be attached by wearing limit shaft.
Especially, one end of the sliding block and two tapered wedges is stretched out the take-up housing and set, one end of the take-up housing
It is fixed with the pressing plate for sliding block and two tapered wedges to be fixed.
Especially, the both sides of the take-up housing are assemblied on mould bases plate by the way that press strip is spacing.
Especially, one end of the sliding block offers the T-shape slot for connecting power source.
Beneficial effects of the present invention are that not only structure is simple for the inner core pulling structure of the injection mold compared with prior art
Single, cost is low；And the stable and reliable operation in actual production process, improve the quality of injecting products.
Brief description of the drawings
Fig. 1 is the explosive view of the inner core pulling structure for the injection mold that the specific embodiment of the invention 1 is provided；
Fig. 2 is the sliding block and two tapered wedges of the inner core pulling structure for the injection mold that the specific embodiment of the invention 1 is provided
Assembling schematic diagram；
Fig. 3 is the dimensional structure diagram of the inner core pulling structure for the injection mold that the specific embodiment of the invention 1 is provided.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 to Fig. 3, in the present embodiment, a kind of inner core pulling structure of injection mold include sliding block 1, two
Tapered wedges 2, take-up housing 3 and wearing plate 4, one end both sides of the sliding block 1 can slidably be provided with two relatively by dovetail groove 5
Tapered wedges 2, the sliding block 1 and two tapered wedges 2 are arranged in the take-up housing 3, and the one of the sliding block 1 and two tapered wedges 2
End is stretched out the take-up housing 3 and set, and one end of the take-up housing 3 is fixed with for sliding block 1 and two tapered wedges 2 to be fixed
Pressing plate 6, the other end of the sliding block 1 offers the T-shape slot 7 for connecting power source.
Correspondence offers axis hole on the sliding block 1 and on the two side of the take-up housing 3, by wearing in both axis holes
Limit shaft 8 is attached.
The bottom of described two tapered wedges 2 extends downwardly limited location boss 9, coordinates the positive stop lug boss 9 in described wear-resisting
The stopper slot 10 of two " L " types is offered on plate 4, the positive stop lug boss 9 is arranged in the stopper slot 10, the take-up housing 3
Can movably it be arranged on the wearing plate 4, and the both sides of the take-up housing 3 are assemblied on mould bases plate by the way that press strip 11 is spacing.
The above-mentioned core-pulling mechanism course of work：Die sinking rear slider 1 starts movement under power source pulling, and two tapered wedges 2 exist
Under the drive of sliding block 1, while the position-limiting action that the A of stopper slot 10 is in positive stop lug boss 9 causes two tapered wedges 2 to be slided along vertical
The direction of motion of block 1 moves (direction of arrow in Fig. 2 represents the direction of motion of sliding block and two tapered wedges), i.e. product core pulling direction
It is mobile, complete first time core pulling action；Sliding block 1 is continued to move to, and now two tapered wedges 2 are had been detached from the A of stopper slot 10
It is spacing, at this moment sliding block 1, two tapered wedges 2 and take-up housing 3 by limit shaft 8 under the pulling of sliding block 1 together along slide block movement side
Spacing at the B of stopper slot 10 to movement, now whole core pulling campaign terminates, and completes core pulling.
Above example is the general principle and characteristic for elaborating the present invention, and the present invention is not limited by above-mentioned example,
Without departing from the spirit and scope, the present invention also has various change and change, and these changes and modifications are both fallen within
In scope of the claimed invention.The scope of the present invention is defined by the appended claims and its equivalents.
