Description
Technical field
A kind of injection mold is the utility model is related to, belongs to injection molding technology field.
Background technology
When refrigerator drawer product has some side openings or side concave shape, core-pulling mechanism need to be designed on mould.Mould is taken out
Core divides cavity core pulling and dynamic model core pulling according to mechanism position, according to the power source of core pulling and the core pulling of extension set tool or loose core of oil cylinder.Fig. 1
For a kind of structure of cover half loose core of oil cylinder of generally use.Its principle is to drive core-pulling mechanism to enter or move back completion using oil cylinder power
Core pulling.Oil cylinder also has locking effect concurrently in the mechanism.
When side opening or side concave shape size are small, required oil cylinder locking power is little, and the oil cylinder of suitable dimension cylinder diameter may be selected,
When side opening or larger side concave shape size, required oil cylinder locking power is big, and the oil cylinder of the large scale cylinder diameter difficulty on mould has position
Installed.
The content of the invention
The purpose of this utility model is：A kind of refrigerator drawer die cylinder core pulling locking mechanism is provided, to solve to work as side
When hole or larger side concave shape size, required oil cylinder locking power is big, and the oil cylinder of the large scale cylinder diameter difficulty on mould has position progress
The problem of installation.
To solve the above problems, intend using such a refrigerator drawer die cylinder core pulling locking mechanism, including it is dynamic model, right
The cover half that should be arranged above dynamic model and the core pulling being arranged between dynamic model and cover half, core pulling are arranged between dynamic model and cover half
The side of product die cavity, the opposite side of the core pulling relative with product die cavity side opening or side concave shape side are correspondingly arranged on oil cylinder,
The piston rod of oil cylinder holds out against the side for being arranged at core pulling, and the upper cover of piston rod of oil cylinder is provided with contiguous block, and contiguous block is backwards to core pulling one
The downside at end is ramp structure, and contiguous block is additionally provided with latch segment on the downside of core pulling one end, pressed between latch segment and dynamic model
Provided with spring.
In foregoing locking mechanism, it is also inclined ramp structure, and two is oblique that latch segment, which is corresponded at the ramp structure of contiguous block,
Face is parallel；
In foregoing locking mechanism, the lower end of latch segment is provided with spring groove, and the upper end of dynamic model corresponds to be offered at spring groove
Dynamic model spring groove, the both ends of the spring are respectively arranged in spring groove and dynamic model spring groove；
In foregoing locking mechanism, the piston rod of the oil cylinder through cover half and extends the side of cover half inner core pulling.
Compared with prior art, the utility model on the basis of original mould oil cylinder pulled core structure tie again by the locking of increase by one
Structure, core pulling is locked jointly using latch segment and oil cylinder, i.e. assurance function, reduce oil cylinder bore size again.
Brief description of the drawings
Fig. 1 is a kind of structural representation of currently used cover half loose core of oil cylinder structure；
Fig. 2 is structural representation of the present utility model.
Embodiment
Embodiment：
Reference picture 2, the present embodiment provide a kind of refrigerator drawer die cylinder core pulling locking mechanism, including dynamic model 1, correspondingly set
The core pulling 3 for being placed in the cover half 2 of the top of dynamic model 1 and being arranged between dynamic model 1 and cover half 2, core pulling 3 are arranged at dynamic model 1 and cover half 2
Between product die cavity 4 side, the opposite side of the core pulling 3 relative with the side opening of product die cavity 4 or side concave shape side is correspondingly arranged
There is oil cylinder 5, the piston rod of oil cylinder 5 holds out against the side for being arranged at core pulling 3, and the piston rod of oil cylinder 5 through cover half 2 and extends cover half 2
The side of inner core pulling 3, the upper cover of piston rod of oil cylinder 5 are provided with contiguous block 6, and contiguous block 6 is inclined-plane knot backwards to the downside of the one end of core pulling 3
Structure, contiguous block 6 are additionally provided with latch segment 7 on the downside of the one end of core pulling 3, and latch segment 7 is corresponded at the ramp structure of contiguous block 6
For inclined ramp structure, and two inclined-planes are parallel, and pressure is provided with spring 8 between latch segment 7 and dynamic model 1（Stage clip）, latch segment 7
Lower end is provided with spring groove 71, and the upper end of dynamic model 1 corresponds to and dynamic model spring groove 11 is offered at spring groove 71, and the two of the spring 8
End is respectively arranged in spring groove 71 and dynamic model spring groove 11.
Using when, make band inclined-plane contiguous block 6, latch segment 7, and latch segment 7, spring 8 are fixed on dynamic model 1, lock
Block 7 can move up and down.
During core pulling, the piston rod of oil cylinder 5 is displaced outwardly, and drives contiguous block 6, core pulling 3 to move, using under the inclined-plane of contiguous block 6
Latch segment 7 inclined-plane is pressed, makes latch segment 7 overcome the elastic force of spring 8 to move downward, makes inclined-plane and core pulling 3 before and after latch segment 7, cover half 1
Inclined-plane departs from, and completes core pulling.
During active and inactive mold matched moulds, the piston rod of oil cylinder 5 moves inward, and drives contiguous block 6, core pulling 3 to move return, meanwhile, in bullet
In the presence of spring 8, latch segment 7 is bonded with the inclined-plane of core pulling 3, cover half 1, completes loose core of oil cylinder locking.
