Description
Technical field:
This utility model relates to die casting equipment technical field, a kind of rational in infrastructure,
The die casting with pouring gate structure easy to use.
Background technology:
Die casting is the technology that metal forming field is conventional, it by by liquid metal with high
Speed fills mold cavity, the method obtaining foundry goods under the effect of the pressure after cooled and solidified.By
Being filled into die cavity in metallic solution with the state of high velocity jet, in die cavity, original air has little time
Discharge, be inevitably trapped in inside workpiece, cause foundry goods to there is pore, have impact on foundry goods
Quality.
Being easily caused foundry goods in present stage press casting procedure and pore class defect occur, product yields is low,
Cast gate being faced to the mould of multiple core, the most easily impact core forms whirlpool
Stream volume gas, causes core bore to pull seriously.
Additionally, the size and shape of the mold cavity of current each die casting is changeless,
In use need different products is offered the mould of different size size, fitting of mould
Answering property is poor, adds production cost.
Summary of the invention:
This utility model is for shortcoming and defect present in prior art, it is proposed that a kind of structure
Rationally, the die casting with pouring gate structure easy to use.
This utility model can be reached by following measures:
A kind of die casting with pouring gate structure, it is characterised in that be provided with fixed half and moving half, fixed
Mould matches with dynamic model formation mold cavity, and mold cavity is provided with charging aperture and exhaust passage, described in enter
Material mouth is provided with cone barrel runner, and cone barrel runner connects center annular cast gate, described row
The front end of gas passage is connected with mold cavity, and the back segment of exhaust passage extends outward two aerofluxuss
Mouthful, each air vent is respectively equipped with exhaust gear, exhaust gear include exhaustor, air pump,
Electromagnetic valve, is additionally provided with controller and is connected with two exhaust gears respectively.
Being provided with regulating block in mold cavity described in the utility model, regulating block is through cardan shaft and mold cavity
Outside trimming motor is connected, and regulating block height is highly consistent with mold cavity.
In this utility model mold cavity each side set a regulating block, each regulating block divides
It is not connected with trimming motor through cardan shaft.
This utility model dynamic model is provided with, with the contact surface of cover half, the sealing mechanism matched, including
Seal groove and the seal boss matched with seal groove and O-ring seal, be used for preventing at workpiece
In casting cycle, gas enters, and causes workpiece quality the most up to standard.
This utility model, before casting, first passes through trimming motor to the regulating block in mold cavity
Position is adjusted, and changes the size of mold cavity so that it is after consistent with the casting dimension produced,
Mold cavity bled process by exhaust gear again, owing to being provided with dual-port exhaust passage,
Two set exhaust gears can be rapidly completed the application of vacuum to mold cavity, and controller is in pump-down process
After, driving closed electromagnetic valve, hydraulic pressure unit promotes forward block to close exhaust passage, now
It is pressed into liquid metal again, it is possible to make the remained gas scale of construction in casting workpiece significantly drop by charging aperture
Low, it is to avoid workpiece exists bubble, by cast gate and cone barrel runner, it is possible to be prevented effectively from shape
Become eddy current volume gas, improve the quality of workpiece further.
Accompanying drawing illustrates:
Accompanying drawing 1 is structural representation of the present utility model.
Reference: mold cavity 1, exhaust passage 2, cone barrel runner 3, air vent 4, regulating block
5, cardan shaft 6, trimming motor 7.
Detailed description of the invention:
Below in conjunction with the accompanying drawings this utility model is further described.
As shown in drawings, the utility model proposes a kind of die casting with pouring gate structure,
It is characterized in that being provided with fixed half and moving half, cover half matches with dynamic model and forms mold cavity 1, mould
Chamber 1 is provided with charging aperture and exhaust passage 2, and described charging aperture is provided with cone barrel runner 3, cone
Connect in cylindrical flow channel 3 and have center annular cast gate, the front end of described exhaust passage 2 and mold cavity
1 is connected, and the back segment of exhaust passage 1 extends outward two air vents 4, each air vent
Being respectively equipped with exhaust gear on 4, exhaust gear includes exhaustor, air pump, electromagnetic valve, also sets
Controller is had to be connected with two exhaust gears respectively.
Mold cavity described in the utility model is provided with regulating block 5, regulating block 5 through cardan shaft 6 with
Trimming motor 7 outside mold cavity 1 is connected, regulating block 5 height and mold cavity height one
Cause.
In this utility model, mold cavity 1 each side sets a regulating block, each regulating block
It is connected with trimming motor through cardan shaft respectively.
This utility model dynamic model is provided with, with the contact surface of cover half, the sealing mechanism matched, including
Seal groove and the seal boss matched with seal groove and O-ring seal, be used for preventing at workpiece
In casting cycle, gas enters, and causes workpiece quality the most up to standard.
This utility model, before casting, first passes through trimming motor to the regulating block in mold cavity
Position is adjusted, and changes the size of mold cavity so that it is after consistent with the casting dimension produced,
Mold cavity bled process by exhaust gear again, owing to being provided with dual-port exhaust passage,
Two set exhaust gears can be rapidly completed the application of vacuum to mold cavity, and controller is in pump-down process
After, driving closed electromagnetic valve, hydraulic pressure unit promotes forward block to close exhaust passage, now
It is pressed into liquid metal again, it is possible to make the remained gas scale of construction in casting workpiece significantly drop by charging aperture
Low, it is to avoid workpiece exists bubble, by cast gate and cone barrel runner, it is possible to be prevented effectively from shape
Become eddy current volume gas, improve the quality of workpiece further.
