Description
【Technical field】
The present invention relates to a kind of flow passage structure, more particularly to a kind of flow passage structure of die casting.
【Background technology】
Some metal works would generally use the mode of die casting to be molded, such as the safety belt mandrel of automobile.
Refering to Figure 1, Fig. 1 depicts a kind of flow passage structure schematic diagram of die casting of the prior art.The die casting
Molding 10 one end of product of mold institute has pillar 11, therefore corresponds in one end of mold upper impression with deep hole, the prior art
Die casting there is the flow passage structure 12 sequentially set up, close to the cavity 15 of flow passage structure 12, the exhaust knot of 15 side of cavity
Structure 13, and the deep hole is set on one end of the cavity 15.
Current flow passage structure 12 is the glue-feeder 14 using single direction, deep hole position is directed toward, it is possible thereby to utilize angle
Degree factor makes deep hole position fill rapidly, so as to which the air in deep hole position be made to exclude in time by filling velocity, avoids causing to wrap
The phenomenon that wind.
However, if the glue position of the head end of 10 pillar 11 of product is excessively thin, the soup stock in deep hole position can not still fill rapidly, make
The air obtained in deep hole can not discharge, so as to become the mould end of flowing so that the product 10 produced is made in deep hole location
Into packet wind, cold burden phenomenon.
In view of this, it is really necessary to develop a kind of flow passage structure of die casting, with solve above-mentioned deep hole location packet wind,
The problem of cold burden.
【Invention content】
It is therefore an object of the present invention to provide a kind of flow passage structure of die casting, prior art compression mod can be solved
Has the problem of when having deep hole in cavity side face, the product produced easily causes packet wind, cold burden.
In order to achieve the above object, the flow passage structure of die casting of the invention, the die casting have what is sequentially set up
Flow passage structure, cavity and exhaust structure, one end of the cavity have a deep hole, and the vertical section area of flow passage structure part is along soup
Stream is tapered into direction, and the glue-feeder of the flow passage structure is straight to be directed toward the cavity positions, the exhaust knot in single flow direction
The width of structure is slightly less than the width of the cavity.
Optionally, the flow passage structure includes sprue and runner, the nozzle connection of sprue and die casting, shunting
The one end in road is connect with sprue, and other end connection glue-feeder, the vertical section area of the sprue tapers into.
Optionally, the width edge of the sprue flows to direction and narrows from the width.
Optionally, the thickness of the sprue is thinning by thickness along direction is flowed to.
Compared to the prior art, the flow passage structure of die casting of the invention, due to the vertical section area of flow passage structure
It tapers into, is designed to gradual change type, can play the role of accelerating filling, and glue-feeder is designed to solely straight directing
Chamber position increases the sectional area of filling, is also filling the width design of exhaust structure into the width for being slightly less than the cavity
In the process, the sectional area of exhaust is increased.The end of flowing, the gas in cavity will not be become at deep hole at the time of molding as a result,
It will not be wrapped at deep hole, packet wind, cold burden phenomenon are no longer generated at the deep hole of cavity side.
【Description of the drawings】
Fig. 1 is painted a kind of flow passage structure schematic diagram of die casting of the prior art.
Fig. 2 is painted the structure diagram of one preferred embodiment of flow passage structure of the die casting of the present invention.
【Specific embodiment】
It please refers to shown in Fig. 2, the structure that Fig. 2 is schematically shown as one preferred embodiment of flow passage structure of the die casting of the present invention is shown
It is intended to.
The flow passage structure of the die casting of the present invention, molding 100 one end of product of die casting institute have pillar 110,
The die casting has flow passage structure 120, cavity 150 and the exhaust structure 130 sequentially set up, and one end of the cavity 150 has
Deep hole forming pillar 110, the vertical section area of 120 part of flow passage structure flow to direction along soup stock and taper into, the runner
The glue-feeder 140 of structure 120 is in single flow direction, and straight to be directed toward 150 position of cavity, the width of the exhaust structure 130 is smaller
In the width of the cavity 150.
Wherein, the flow passage structure 120 includes sprue 121 and runner 122, the spray of sprue 121 and die casting
Mouth 160 connects, and one end of runner 122 is connect with sprue 121, other end connection glue-feeder 140, in order to preferably accelerate to fill
It fills out, the vertical section area of the sprue 121 flows to direction along soup stock and tapers into.
Wherein, the width of the sprue 121 flows to direction along soup stock and narrows from the width, and makes the vertical section of sprue 121
Area tapers into or the thickness of the sprue 121 flows to direction by thick thinning along soup stock, makes the vertical of sprue 121
Area of section taper into or the two at the same variation taper into the vertical section area of sprue 121.
The vertical section product area of flow passage structure 120 tapers into as a result, that is, is designed to gradual change type, can be filled in soup stock
Have accelerated motion during filling out, play the role of accelerating filling, reduce because stream it is long than it is long due to cause the generation of cold burden.
Glue-feeder 140 is designed to solely straight 150 position of direction cavity, increases the sectional area of filling, Neng Goujun
Even filling enables deep hole location to be filled simultaneously with other positions, will not generate cause to have in deep hole when filling uneven it is cold
The accumulation of material.
By the width design of exhaust structure 130 into the width for being slightly less than cavity 150, the sectional area of exhaust is increased, is being filled
During filling out, the temperature of soup stock can be effectively kept and occurred the phenomenon that not generating anti-package, cause volume gas and packet wind.
Compared to the prior art, the flow passage structure of die casting of the invention will not become flowing at the time of molding at deep hole
End, the gas in cavity 150 will not be wrapped at deep hole, and it is existing no longer to generate packet wind, cold burden at the deep hole of 150 side of cavity
As.
