Abstract
The utility model discloses a kind of lever arc core-pulling mechanisms, and block, oblique drawn needle, pumping block pull rod, tiltedly circular arc pressing plate, pumping guide pad, sliding block, oil cylinder are taken out including moving platen, circular arc；The cylinder body of the oil cylinder is fixedly mounted on the side wall of moving platen, and the piston rod of oil cylinder stretches into moving platen and is connected with sliding block, and sliding block is slipped in moving platen, is tiltedly taken out guide pad and is fixed on sliding block；The circular arc pressing plate is fixed in moving platen, circular arc is taken out block and is slipped on circular arc pressing plate, the inner end of oblique drawn needle is fixed on circular arc and takes out on block, take out one end of block pull rod with geosynclinal block coordinate on slip and tiltedly taking out on guide pad, the other end for taking out block pull rod is hinged on circular arc pumping block.Since the oil cylinder of the utility model is by driving sliding block, tiltedly taking out guide pad, take out block pull rod circular arc is driven to take out block and carry out circular arc along circular arc pressing plate and move, realize product circular hole core pulling of the oblique drawn needle from injection molding, have the advantages that having stable behavior is reliable.
Description
Technical field
The utility model is related to a kind of injection mold, more particularly to a kind of lever arc core-pulling mechanism.
Background technology
Plastics injection mould is the instrument for producing plastic products, is widely used general.Plastic product on existing market
Structure becomes increasingly complex, and as shown in Figure 1A, some plastic products 10 have arc inside groove 101, thus it requires mold also have can
Be molded the structure of this arc inside groove, this requires with it is a kind of being capable of the intact knot that mold is extracted out from arc inside groove
Structure, but this mold that can quickly and easily extract out has certain difficulty, and this respect is also always people in the art
Member's problem to be solved.
The content of the invention
The purpose of this utility model is to provide a kind of reliable lever arc core-pulling mechanisms of having stable behavior.
To achieve the above object, the technical solution of the utility model is：
The utility model is a kind of lever arc core-pulling mechanism, takes out block, oblique drawn needle including moving platen, circular arc, takes out block drawing
Bar, circular arc pressing plate tiltedly take out guide pad, sliding block, oil cylinder；The cylinder body of the oil cylinder is fixedly mounted on the side wall of moving platen, oil
The piston rod of cylinder stretches into moving platen and is connected with sliding block, and sliding block is slipped in moving platen, tiltedly takes out guide pad and is fixed on sliding block；Institute
The circular arc pressing plate stated is fixed in moving platen, and circular arc is taken out block and slipped on circular arc pressing plate, and the inner end of oblique drawn needle is fixed on circular arc pumping
On block, cavity is stretched into the outer end of oblique drawn needle, take out one end of block pull rod with geosynclinal block coordinate on slip and tiltedly taking out on guide pad, pumping block
The other end of pull rod is hinged on circular arc and takes out on block, and sliding block drives circular arc to take out arcwall face shifting of the block along circular arc pressing plate by taking out block pull rod
It is dynamic.
The circular arc, which takes out block, oblique drawn needle, pumping block pull rod, circular arc pressing plate, two groups, and two groups of circular arcs take out block, oblique drawn needle, pumping
Block pull rod, circular arc pressing plate are symmetrical arranged.
After using the above program, since the utility model includes moving platen, circular arc takes out block, oblique drawn needle, pumping block pull rod, circular arc
Pressing plate tiltedly takes out guide pad, sliding block, oil cylinder；Oil cylinder is by driving sliding block, tiltedly taking out guide pad, pumping block pull rod driving circular arc pumping block edge
Circular arc pressing plate carries out circular arc movement, realizes product circular hole core pulling of the oblique drawn needle from injection molding, reliable with having stable behavior
Advantage.
The utility model is further described in the following with reference to the drawings and specific embodiments.
Description of the drawings
Figure 1A is a kind of plastic products with arc inside groove；
Fig. 1 is the structure chart of the utility model core pulling part；
Fig. 2 is the molding state diagram of the utility model；
Fig. 3 is the die opening state figure of the utility model.
Specific embodiment
As shown in Figure 1-Figure 3, the utility model is a kind of lever arc core-pulling mechanism, and block is taken out including moving platen 1, circular arc
2nd, oblique drawn needle 3, pumping block pull rod 4, tiltedly circular arc pressing plate 5, pumping guide pad 6, sliding block 7, oil cylinder 8.
The cylinder body of the oil cylinder 8 is fixedly mounted on the side wall of moving platen 1, the piston rod of oil cylinder 8 stretch into moving platen 1 and
It is connected with sliding block 7, sliding block 7 is slipped in moving platen 1, is tiltedly taken out guide pad 6 and is fixed on sliding block 7；The circular arc pressing plate 5 is fixed
In moving platen 1, circular arc is taken out block 2 and is slipped on circular arc pressing plate 5, and the inner end of oblique drawn needle 3 is fixed on circular arc and takes out on block 2, oblique drawn needle 3
Outer end stretch into cavity, take out one end of block pull rod 4 with geosynclinal block coordinate on slip and tiltedly taking out on guide pad 6, pumping block pull rod 4 it is another
One end is hinged on circular arc and takes out on block 2, and sliding block 7 drives circular arc pumping block 2 to be moved along the arcwall face of circular arc pressing plate 5 by taking out block pull rod 4.
In the present embodiment, the circular arc, which takes out block, oblique drawn needle, pumping block pull rod, circular arc pressing plate, two groups, and two groups of circular arcs are taken out
Block 2, oblique drawn needle 3, pumping block pull rod 4, circular arc pressing plate 5 are symmetrical arranged.
The operation principle of the utility model：
After die sinking, 8 core pulling 24mm of oil cylinder tiltedly takes out the and then mobile 24mm of guide pad 6,18mm or so is tiltedly taken out with this oblique drawn needle 3,
So that tiltedly drawn needle 3 departs from plastic products 10, while takes out block pull rod 4 and also moves 24mm, take out block pull rod 4 haul circular arc take out block 2 along
Circular arc pressing plate 5 moves outward, finally so that circular arc takes out block 2 and also completely disengages material products 10, causes product that can demould completely.
The above is only the utility model preferred embodiment, therefore the utility model implementation cannot be limited with this
Scope, i.e., the equivalent changes and modifications made according to present utility model application the scope of the claims and description all should still belong to this reality
In the range of being covered with new patent.
