Abstract
The present invention relates to a kind of extruding pushing structure for die casting, including promoting oil cylinder, oil cylinder axle and extruding core_pulling pole, oil cylinder axle is installed in described promotion cylinder upper end, it is vertically-mounted on described oil cylinder axle to have extruding core_pulling pole, socket is provided with stop collar on described oil cylinder axle top and extruding core_pulling pole, described spacing set upper side is provided with the core pulling set of covering extruding core pulling boom end, and described extruding core pulling boom end is mutually pushed up with product core pulling portion.The features such as present invention avoids the shaping of product sbrinkage blowhole with improve product quality, while production cost is not increased, improves production efficiency.
Description
Technical field
The present invention relates to die casting supplementary structure field, more particularly to a kind of extruding for die casting promotes knot
Structure.
Background technology
Die casting due to extruding force, can cause that product is answered when manufacture structure complex product
Miscellaneous position occurs sbrinkage blowhole, and these sbrinkage blowholes are very difficult to cancel, and is under normal circumstances the pressure by controlling injection aluminium liquid
Cancel sbrinkage blowhole with the quantity of injection aluminium liquid, this mode not merely improves the cost of product, also reduces the life of product
Efficiency is produced, in order to solve the above problems, a kind of new supplementary structure is designed and is necessary.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of extruding pushing structure for die casting, with raising
Product quality, the shaping for avoiding while production cost is not increased product sbrinkage blowhole, improve the spies such as production efficiency
Point.
The technical solution adopted for the present invention to solve the technical problems is：A kind of extruding for die casting is provided to promote
Structure, including oil cylinder, oil cylinder axle and extruding core_pulling pole are promoted, oil cylinder axle is installed in described promotion cylinder upper end, it is described
Vertically-mounted on oil cylinder axle to have extruding core_pulling pole, socket is provided with stop collar on described oil cylinder axle top and extruding core_pulling pole,
Described spacing set upper side is provided with the core pulling set of covering extruding core pulling boom end, and described extruding core pulling boom end is taken out with product
Core is mutually pushed up.
Described promotion oil cylinder bottom is provided with fixed plate, and described promotion oil cylinder is connected by fixed plate with mould, institute
The extruding core_pulling pole stated is inserted into mould and is contacted with the die cavity in mould.
Covered by connecting shaft between described oil cylinder axle and extruding core_pulling pole and be connected.
The diameter covered with diameter greater than core pulling of described stop collar.
Beneficial effect：The present invention relates to a kind of extruding pushing structure for die casting, with improve product quality,
The features such as shaping of product sbrinkage blowhole is avoided while not increasing production cost, production efficiency is improved.

Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read instruction of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiments of the present invention are related to a kind of extruding pushing structure for die casting, as shown in Fig. 1-3, including
Oil cylinder 2, oil cylinder axle 7 and extruding core_pulling pole 6 are promoted, oil cylinder axle 7, described oil cylinder are installed in the described upper end of promotion oil cylinder 2
Vertically-mounted on axle 7 to have extruding core_pulling pole 6, socket is provided with stop collar 3 on the described top of oil cylinder axle 7 and extruding core_pulling pole 6,
The described upper end of stop collar 3 is provided with the core pulling set 4 of covering extruding core_pulling pole 6 end, the described end of extruding core_pulling pole 6 and product
Product core pulling portion mutually pushes up.
The described bottom of promotion oil cylinder 2 is provided with fixed plate 1, and described promotion oil cylinder 2 passes through fixed plate 1 and mould phase
Even, described extruding core_pulling pole 6 is inserted into mould and is contacted with the die cavity in mould.
5 are covered between described oil cylinder axle 7 and extruding core_pulling pole 6 by connecting shaft to be connected.
The diameter with diameter greater than core pulling set 4 of described stop collar 3.
Embodiment
When needing to produce product using die casting, this structure is arranged in mould first, according to compression mod
Structure in tool die cavity, reasonably arranges the position of this structure, and this structure and mould structure are caused by fixed plate 1, and extrudes
The end of core_pulling pole 6 needs to insert mould cavity, the position Xiang Ding extruded with product needed, and stop collar 3 is mainly used in avoiding extruding
Core_pulling pole 6 and contacting dies, the situation that the extruding abrasion of core_pulling pole 6 occurs cover 4 so that product extruded parts by installing core pulling
Can embark on journey, it is to avoid core pulling position is damaged.
