Description
Technical field
The utility model belongs to industrial manufacturing technology field, more particularly to a kind of die casting of excellent in durability.
Background technology
Traditional die casting is the mentality of designing using straight channel, that is, liquid material is directly flowed into by cast gate
Runner, then be directly entered by runner in die cavity, temperature high pressure is big during due to liquid material supplied materials, so directly pours type
It is easy to damage mould in chamber, causes die life of short duration.
A kind of compound runner aluminium alloy castings mould that the utility model patent of Patent No. 201420388467.3 is announced
Tool, the mould is to be used to enter row buffering to liquid material by setting multiple runners, and angle between runner being set into 90 °,
Although so can also reach the effect of protection mould, its buffering effect is too strong, product is produced aberration, particularly works as
When producing sheet hardware products, because cavity space is small, it is also easy to block the corner location of runner, it is impossible to complete die casting operation；
In addition, the mould is due to using multiple runners, complicated, cost of manufacture is high, is not suitable for batch production.
Utility model content
The purpose of this utility model is that offer is a kind of simple in construction, can be good at playing cushioning effect, again will not shadow
The die casting of the excellent in durability of clicker shape hardware products quality.
To achieve these goals, the utility model is adopted the following technical scheme that：
A kind of die casting of excellent in durability, including cast gate, the sprue that is arranged on cast gate and for product into
The die cavity of type, the sprue end is provided with dashpot at least provided with a runner between runner and die cavity, the buffering
Groove vertical runners are set, and buffering slot length is consistent with die cavity length, and the opposite side of die cavity current buffer groove is provided with multiple exhausts
Passage, the end of the exhaust duct is provided with waveform passage.
Further, the dashpot is single, and its cross section is arc.
Further, the dashpot is be set up in parallel multiple, is formed wavy.
Further, the sprue is located at the lower section of cast gate, and sprue has difference in height with cast gate, with certain
Cushioning effect.
Compared with prior art, the utility model has the following advantages that：
A kind of die casting of excellent in durability of the present utility model, design science rationally, is carried out by designing runner
Buffer for the first time, runner reconnects dashpot and buffer for the second time, fully the high-temperature liquid state raw material pressure and stream after buffering
Speed is obtained for certain reduction, and too big damage will not be caused to mould, can extend the mold use life-span；Due to setting
Runner so that shunting and buffer synchronisation are carried out, good buffer effect will not produce the situation for blocking runner, not influence product
Quality；And the utility model structure fabrication cost is low, it is adapted to produce in enormous quantities.
Brief description of the drawings
Fig. 1 is the schematic diagram of a preferred embodiment.
Fig. 2 is the product schematic diagram that mould described in the utility model is produced.
Embodiment
A kind of die casting of excellent in durability of the utility model is made into one below in conjunction with specific embodiment and accompanying drawing
Step is described in detail.
As depicted in figs. 1 and 2, in a preferred embodiment, a kind of die casting of good endurance of the present utility model, mould
Inside has die cavity 5, and the shape of die cavity 5 is consistent with shape of product, and high-temperature liquid state raw material is cooled into product after entering die cavity 5.Should
Mould includes cast gate 1 and the sprue 2 being arranged on cast gate 1, and the end of the sprue 2 is at least provided with a runner 3, shunting
The high-temp liquid raw material that road 3 can flow out sprue 2 are shunted, and make the more uniform entrance die cavity 5 of high-temperature liquid state raw material
It is interior, play a part of tentatively buffering.The supplied materials side of die cavity 5 is provided with dashpot 4, and die cavity 5 is connected by dashpot 4 with runner 3
Connect.The vertical sprue 2 of dashpot 4 is set, and its length is consistent close to the side length of sprue 2 one with die cavity 5.Buffered in the present embodiment
Groove 4 is the deep-slotted chip breaker that cross section is arc, when high-temperature liquid state raw material streams cross dashpot 4, due to the design feature of deep-slotted chip breaker, energy
Enough play certain cushioning effect so that high-temperature liquid state raw material will not directly rush at die cavity 5, reduction high-temperature liquid state raw material enter
Enter flow velocity during die cavity 5, reduce the abrasion to mould, improve service life.In addition, dashpot 4 can also be multiple arcs
Shape groove is connected, and forms wave-like, and its cushioning effect is bigger, it is adaptable to the small product of width.
The opposite side of the current buffer groove 4 of die cavity 5 is additionally provided with multiple exhaust passages 6, and exhaust passage 6 is used to discharge in mould
Gas so that high-temperature liquid state raw material are easier to the full whole die cavity 5 of filling.It is logical in exhaust in order to reach more preferable exhaust effect
The end in road 6 is provided with waveform passage 7, and waveform passage 7 can reduce the speed of exhaust, it is ensured that the adequacy of exhaust, subtract
The generation of the phenomenons such as few trapped gas, casting current mark, cold shut and misrun.
In order to reach more preferable die casting effect, wherein sprue 2 and cast gate 1 has certain altitude poor, and sprue 2, which is located at, to be poured
The lower section of mouth 1 so that raw material, which are entered through when cast gate 1 enters sprue 2, also has certain cushioning effect.
Although being to combine embodiments above to carry out to description of the present utility model, it is familiar with the art
Personnel many replacements, modifications and variations can be carried out according to above-mentioned content, are obvious.Therefore, it is all such
Substitute, improve and change and be included in the spirit and scope of appended claims.
