Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.Additionally, institute in this utility model disclosed below each embodiment
As long as the technical characteristic being related to does not constitute conflict each other and can just be mutually combined.
As shown in figure 4, a kind of sprue bush for die casting that this utility model embodiment is provided, which includes sprue bush
Molten metal material is delivered to by part 1 and coolant jacket 2, wherein sprue bush part 1 for the passage as molten metal material
In the mould specified, coolant jacket 2 is sleeved on the outside of sprue bush part 1, for realizing the regulation and control of 1 temperature of sprue bush part.It is logical
Cooperating for above-mentioned all parts is crossed, coolant jacket and the water circulation welding position of sprue bush part can be avoided to be affected by high temperature
Showing drainage, and can remove coolant jacket individually carries out being tempered destressing heat treatment to sprue bush part, improves cast gate
Set service life.
More specific detail will be carried out one by one will to all parts below.
As shown in Fig. 2 sprue bush part 1 is hollow cylindrical structure, its one end is provided with flange 11, cylindrical structural
Flow channel of the hollow space i.e. as motlten metal.Specifically, flange 11 is step-like structure, and the diameter which is located at outer end is big
In inner diameter, so can effectively prevent from being sleeved on coming off for the coolant jacket 2 outside sprue bush part 1.
As shown in figure 3, coolant jacket 2 is double-decker, which includes coolant jacket inner ring 21 and coolant jacket outer ring 22, and cools down
Set inner ring 21 and coolant jacket outer ring 22 are fixed together by way of welding, such as shown in Fig. 3 (c), with this so that in coolant jacket
The temperature adjusting structure that circle 21 and coolant jacket outer ring 22 form a whole as sprue bush part 1, with Stability Analysis of Structures, is difficult
The advantages of leak.
Wherein, the outer surface of coolant jacket inner ring 21 is provided with cooling water channel 23, and coolant jacket outer ring 22 is sleeved in coolant jacket
The outside of circle 21, and water inlet 24 and outlet 25 are offered thereon.Specifically, cooling water channel 23 be water annulus, one
End is connected with water inlet 24, and the other end is connected with outlet 25, and water inlet of the cooling water first from coolant jacket outer ring 22 enters ring
One end of shape water channel, then flows through whole water annulus, and the water outlet of coolant jacket outer ring 22 is flowed into by the other end of water annulus
Mouthful, Jing outlets flow out.Temperature adjustment and the control of sprue bush part 1 are realized by the flowing of cooling water.
Further, for the ease of processing and manufacturing, the thickness and Design of length of coolant jacket inner ring 21 and coolant jacket outer ring 22
Into equal, and its length is less than the length of sprue bush part 1.Additionally, the internal diameter of coolant jacket inner ring 21 is equal to sprue bush part 1
The external diameter of cylindrical structural, the internal diameter of coolant jacket outer ring 22 are equal to the external diameter of coolant jacket inner ring 21, easy to assembly to ensure, make whole
Individual sprue bush structure is compact.
As shown in figure 3, the 2 integrated straight female connector of coolant jacket being made up of coolant jacket inner ring 21 and coolant jacket outer ring 22 is mounted in cast gate
The outside of set part 1, its end face are abutted against with the end face of flange 11.Specifically, the end of the end face of coolant jacket 2 and 11 the inner of flange
Face abuts, the equal diameters of its diameter and 11 the inner of flange.Thus, by coolant jacket 2 is socketed in the outer of sprue bush part 1
Portion, and by the flange arrangement on sprue bush part 1, can effectively prevent coolant jacket 2 from coming off.
During use, as coolant jacket of the present utility model is directly sleeved on outside sprue bush part, which is separable, with
Fig. 1 Die Casting Industries sprue bush assembly conventional at present compares, and after sprue bush assembly is often secondary using 8000 moulds, separates cooling
Set, need to only take down coolant jacket 2 carries out being tempered destressing heat treatment to sprue bush part 1, improves sprue bush service life,
Reduce production cost simultaneously.
Pouring bushing for die casting die assembly of the present utility model, increased the stability of die casting production line, reduce leak and
The shutdown for causing, if there is failure also can quick-replaceable and reparation, improve die gate casing service life.
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not
To limit this utility model, all any modifications made within spirit of the present utility model and principle, equivalent and change
Enter, should be included within protection domain of the present utility model.
