In view of this, it is necessary to develop a kind of magnesium alloy die structure of hot runner in fact, to solve the above problems.
【The content of the invention】
It is therefore an object of the present invention to provide a kind of magnesium alloy die structure of hot runner, solves prior art magnesium
Alloy mold needs cast gate and running channel, and then solidification cold burden is produced after formed product, causes raw material magnesium alloy unrestrained
The problem of taking.
In order to achieve the above object, the hot runner structure of magnesium alloy mold provided by the invention, the mould include
The male template sequentially set up, caster, supporting plate, backing plate, mother module core, the hot-fluid are provided with the caster
Road structure includes：
Seal cartridge, one part is in the caster, and another part is in the mother module core；
Nozzle, it is sheathed in the seal cartridge；
Heating coil, between the seal cartridge and the nozzle；
Hot runner manifold, between the caster and the backing plate；
Heater strip, in the hot runner manifold.
Optionally, support block is provided between the backing plate and the hot runner manifold.
Optionally, it is fixed between the support block and the hot runner manifold.
Optionally, there is the first gap between the top of the seal cartridge and the mother module core.
Optionally, the internal diameter of the nozzle head external diameter and the seal cartridge correspondence position has the second gap.
Optionally, the heating coil is controlled using ten king's temperature controllers, and the nozzle is heated.
Optionally, the heater strip is controlled using PLC temperature controllers, and the hot runner manifold is heated.
Optionally, the backing plate is provided with thermal insulation board away from the supporting plate side.
Optionally, fixed between the nozzle and the hot runner manifold by the first screw connection.
Optionally, fixed between the nozzle and the seal cartridge by the second screw connection.
Compared to prior art, using the magnesium alloy die structure of hot runner of the present invention, due to no longer using existing
There are the cast gate and running channel of technology, the magnesium alloy of melting flows directly into nozzle and hot runner manifold by expects pipe, and then
Product produces solidification cold burden after reducing shaping, greatlys save raw material magnesium alloy.
【Brief description of the drawings】
Fig. 1 is schematically shown as a kind of hot flow path cross section structure diagram of magnesium alloy mold of the present invention.
Fig. 2 is schematically shown as a kind of hot flow path cross section structure diagram of magnesium alloy mold of the present invention.
【Embodiment】
Please in conjunction with refering to Fig. 2, Fig. 2 is schematically shown as the die-cast product and its material head of the preferred embodiment of the present invention
Structural representation.
In order to achieve the above object, the hot runner structure of magnesium alloy mold provided by the invention, the mould include
The male template (not shown) sequentially set up, caster 101, supporting plate 102, backing plate 103, the caster
Mother module core 104 is provided with 101, the hot runner structure includes：
Seal cartridge 105, for one part in the caster 101, another part is located at the mother module core
In 104；
Nozzle 106, it is sheathed in the seal cartridge 105；
Heating coil 107, between the seal cartridge 105 and the nozzle 106；
Hot runner manifold 108, between the caster 101 and the backing plate 103；
Heater strip 109, in the hot runner manifold 108.
Wherein, support block 110 is provided between the backing plate 103 and the hot runner manifold 108, due to the hot-fluid
Temperature in guidance tape 108 is very high, and the support block 110 is used for heat-insulated；The support block 110 and the heat
Between runner plate 108 fixed (screw can be used), the fixation to the hot runner manifold 108 can be reached
Effect.
Wherein, there is the first gap between the top of the seal cartridge 105 and the mother module core 104.Institute
Seal cartridge 105 is stated after expanded by heating, its top is bonded with being compressed between the mother module core 104, described
First gap disappears, so as to effectively prevent magnesium alloy from flowing into mould.
Wherein, the internal diameter of the head outer diameter of nozzle 106 and the correspondence position of seal cartridge 105 has the
Two gaps.After the nozzle 106 and the expanded by heating of seal cartridge 105, due to the nozzle 106 with
Differential expansion (degrees of expansion of nozzle 106 is more than seal cartridge 105) between the seal cartridge 105, institute
State to compress between the head of nozzle 106 and the correspondence position of seal cartridge 105 and be bonded, so as to avoid magnesium from closing
Gold flows into the seal cartridge 105 by the nozzle 106.
Wherein, the heating coil 107 is controlled using ten king's temperature controllers, and the nozzle 106 is heated.
The heating coil 107 uses high frequency heating coil, and the heating-up temperature of the nozzle 106 is 580~590 DEG C,
The heating-up temperature may insure that magnesium alloy is in liquid, avoid condensing, while may insure that nozzle 106 will not
Excessive deformation；The heater strip 109 is added using the control of PLC temperature controllers to the hot runner manifold 108
Heat.The operating temperature of the hot runner manifold 108 is 630~650 DEG C, and the operating temperature may insure magnesium alloy
Preferably it is molded.
Wherein, the backing plate 103 is provided with thermal insulation board 111 away from the side of supporting plate 102.The thermal insulation board
111 for heat-insulated between mould and the external world.
Wherein, it is connected between the nozzle 106 and the hot runner manifold 108 by the first screw 112.
The nozzle 106 is avoided to cause to tilt the connection for causing nozzle 106 and hot runner manifold 108 due to thermal expansion difference
Locate material leakage；It is connected between the nozzle 106 and the seal cartridge 105 by the second screw 113.From
And facilitate the integral installation of nozzle 106 and seal cartridge 105.
Compared to prior art, using the magnesium alloy die structure of hot runner of the present invention, due to no longer using existing
There are the cast gate and running channel of technology, the magnesium alloy of melting flows directly into nozzle 106 and hot runner manifold 108 by expects pipe,
And then product reduces generation solidification cold burden after shaping, greatlys save raw material magnesium alloy.
It is noted that the invention is not restricted to above-mentioned embodiment, any person skilled in the art's base
Any simple modification, equivalent change and modification made in technical solution of the present invention to above-described embodiment, all falls
