Description
Technical field
A kind of injection mold is the utility model is related to, 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 components in batches.Refer specifically to heated thawing
Plastics by injection molding machine high pressure inject die cavity, after cooling and solidifying, obtain formed products.
Inner core pulling structure is the common structure of injection mold.It is existing at present big for the inner core pulling structure on injection mold
It is composed of more more parts, there are complicated, production cost are high and the shortcomings that stable and reliable operation is poor.
Utility model content
The purpose of this utility model is to provide a kind of inner core pulling structure of injection mold, it is with simple in structure, cost
The characteristics of low and stable and reliable operation, to solve to ask for above-mentioned existing for the inner core pulling structure of injection mold in the prior art
Topic.
For this purpose, the utility model 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 has extended downwardly positive stop lug boss, coordinates the positive stop lug boss in the limiting slot that two " L " types are offered on the wearing plate, institute
State positive stop lug boss to be arranged in the limiting slot, the take-up housing can be movably arranged on the wearing plate.
Especially, the limit assembly includes the corresponding axis hole being 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 is 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.
The beneficial effects of the utility model are, compared with prior art the inner core pulling structure of the injection mold not only structure
Simply, cost is low；And the stable and reliable operation in actual production process, improve the quality of injecting products.

Embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
Shown in please referring to Fig.1 to Fig.3, in the present embodiment, a kind of inner core pulling structure of injection mold includes 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 is 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 has extended downwardly positive stop lug boss 9, coordinates the positive stop lug boss 9 in described wear-resisting
The limiting slot 10 of two " L " types is offered on plate 4, the positive stop lug boss 9 is arranged in the limiting 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 to move under power source pulling, and two tapered wedges 2 exist
Under the drive of sliding block 1, while the A of limiting slot 10 is in the position-limiting action of positive stop lug boss 9 so that two tapered wedges 2 are slided along vertical
1 direction of motion of block movement (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 continues to move to, and two tapered wedges 2 are had been detached from the A of limiting slot 10 at this time
It is spacing, at this moment 1, two tapered wedges 2 of sliding block 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 limiting slot 10 to movement, whole core pulling campaign at this time terminates, and completes core pulling.
Above example is to elaborate the basic principle and characteristic of the utility model, and the utility model is from above-mentioned example
Limitation, on the premise of not departing from the spirit and scope of the utility model, the utility model also has various changes, these changes
Change and change and both fall within claimed the scope of the utility model.The utility model requires protection scope will by appended right
Ask book and its equivalent thereof.
