Description
Technical field
It the utility model is related to a kind of die casting, and in particular to a kind of die casting synchronous core pulling mechanism, belong to pressure
Casting mould technical field.
Background technology
The essence of die casting is under high pressure effect, liquid or semi-solid-state metal is filled into compression mod with high speed
Have die cavity, and under pressure shaping and cooled and solidified and obtain a kind of forming technology of casting；The product size that die casting goes out
Precision is high, and surface roughness is low, and stock utilization is high, dense structure, has higher intensity and hardness；Using extrusion process,
The metal parts of complex-shaped, the clear-cut deep chamber of thin-walled can be manufactured, can also on die casting direct inlay casting other materials
Part, save precious materials and machining period；It is prerequisite that the mould that structure holds water is that can Die Casting be smoothed out
Condition, and played an important role in terms of casting quality is ensured；Existing die casting species is various, and it can be according to each
Occasion selection uses, such as Chinese Patent Application No.：201420006559.0 a kind of die casting is disclosed, the die casting
Include the die frame that die cavity is opened up inside one, the die frame includes dynamic model and cover half, connects on the die casting
It is connected to a vacuum extractor；A vacuum extractor is connected on die casting, liquid metal can be inputted in gases at high pressure
Before, by the evacuating air in die cavity, it is not necessary to set exhaust outlet on die casting again, solve during casting forming
The problem of stomata can be generated on workpiece, substantially increase the quality of Forming Workpiece；After die cavity is evacuated, opened by oil cylinder
Dynamic band movable pulley, which seals, vacuumizes runner, prevents that liquid metal is excessive, improves the security and air-tightness of die casting；It is existing
There is its inner face of many lids that reinforcement can be set, in the prior art, die casting is made up of double cylinders and a core pulling；Though its
It is so simple in construction, but die casting is not sufficiently stable, and core pulling is comparatively laborious.
Utility model content
To solve the above problems, the utility model proposes a kind of die casting synchronous core pulling mechanism, lock core cylinder energy
It is enough to realize locking and unblock, drive curved pin to move by core pulling cylinder, core pulling is in pullable state along curved pin direction；Reach
The purpose being stripped completely；Core pulling cylinder withdrawing in place after, then the steady ejecting product of push pedal, take out casting.
Die casting synchronous core pulling mechanism of the present utility model, including powered support and track base；The track base two
Face is provided with slide rail；Core pulling cylinder and lock core cylinder are separately installed with the powered support；The institute of its top surface of track base
Stating slide rail activity and being fitted together to has curved pin connection block；The slide rail activity of its bottom surface of track base is chimeric locking contiguous block；Institute
State curved pin connection block front end and upward curved pin is installed；Core pulling is movably installed with the curved pin；The locking contiguous block front end
It is fixed with lock core；The core pulling cylinder and lock core cylinder are connected respectively to gas supply mechanism；During work, after mould matched moulds and die casting
Core pulling cylinder and lock core cylinder are in release state all the time in journey, and keep pressure；After die casting, mould is opened, first by core pulling gas
Cylinder and lock core cylinder withdrawing, core pulling cylinder and lock core cylinder drive curved pin connection block and locking contiguous block action, lock core cylinder reality
Now unlock, meanwhile, core pulling cylinder drives curved pin movement, core pulling is in pullable state along curved pin direction；Reach the complete demoulding
Purpose；Core pulling cylinder withdrawing in place after, then the steady ejecting product of push pedal, take out casting.
Further, the curved pin connection block is H type structures.
Further, it is provided with mounting hole on the powered support and track base.
Further, the slide rail is Ω types and the type of falling Ω structure.
Further, the curved pin connection block protrusion slide rail top surface；The locking contiguous block is no more than slide rail bottom surface.
The utility model compared with prior art, die casting synchronous core pulling mechanism of the present utility model, structure letter
It is single, it is practical, drive curved pin connection block and locking contiguous block to act by core pulling cylinder and lock core cylinder, lock core cylinder is realized
Unblock, meanwhile, core pulling cylinder drives curved pin movement, core pulling is in pullable state along curved pin direction；Reach what is be stripped completely
Purpose；Core pulling cylinder withdrawing in place after, then the steady ejecting product of push pedal, take out casting.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
