[0034] The following descriptions of the embodiments refer to the accompanying drawings to illustrate specific embodiments in which the present invention may be implemented.

[0035] This embodiment discloses a die casting system, which includes an integrated feed barrel. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the integrated feed barrel includes a feed barrel body 1, and the feed barrel body 1 includes an extended head 11 and a tail 12. One end of the extended head 11 is connected to the tail 12, and the other end of the extended head 11 extends outward along the axial direction of the feed barrel body 1. An annular groove 111 is provided in the extended head 11, and the extended head 11 has a cooling hole 112 for connecting the coolant. The cooling hole 112 extends inward from the outer surface of the extended head 11 and is connected to the annular groove 111. A deep hole 121 is provided on an end surface of the tail 12 facing away from the head, and an oblique hole 122 is provided on the outer surface of the tail 12. The oblique hole 122 is connected to the deep hole 121 and forms a cooling channel. The cooling channel is used to be connected to an external cooling device for the circulation of coolant.

[0036] In the feed barrel body 1, the extended head portion 11 and tail portion 12 are interconnected and integrally formed, achieving ease of fabrication and greater structural stability. The tail portion 12 has a deep hole 121 and an oblique hole 122 interconnected to form a cooling channel. An external cooling device is connected to the tail portion 12 and communicates with the cooling channel. The external cooling device is used to provide coolant, allowing the coolant to flow into the cooling channel, thereby cooling the tail portion 12 of the feed barrel body 1.

[0037] In this embodiment, the length of the part of the integrated feed barrel embedded in the mold is extended, that is, the extended head 11 is extended and extended outward along the axial direction of the feed barrel body 1, and a cooling hole 112 is provided on the extended head 11 and is connected to the annular groove 111 inside it, so that an external cooling device can be connected to the cooling hole 112 and connected to the annular groove 111 through the cooling hole 112, and the coolant will flow into the annular groove 111 through the cooling hole 112, thereby realizing cooling and lowering the temperature of the extended head 11 of the feed barrel body 1.

[0038] A cooling channel is added to the tail 12 of the feed barrel body 1, and the length of the part of the integrated feed barrel embedded in the mold is extended. An annular groove 111 is added inside the extended head 11 of the feed barrel body 1, so that the feed barrel body 1 can be cooled through the cooling channel and the annular groove 111. The integrated feed barrel is equipped with a stable cooling device, which enables the integrated feed barrel to have the advantages of long service life and not easy to deform. At the same time, it makes the injection process smoother, reduces downtime, and increases production efficiency.

[0039] In one embodiment, there may be multiple annular grooves 111, which are interconnected. The multiple annular grooves 111 increase the flow path of the coolant within the extended head 11, thereby enhancing the cooling effect on the extended head 11. The pattern and number of the annular grooves 111 are not limited.

[0040] In another embodiment, the annular groove 111 may also be a spiral groove, which has a simple structure and is easy to manufacture.

[0041] There are two cooling holes 112, each connected to the end of the annular groove 111. The two cooling holes 112 serve as reserved coolant inlet and outlet ports and are connected to an external cooling device, allowing the coolant to circulate within the extended head 11, effectively enhancing the cooling effect on the extended head 11.

[0042] like Figure 1 and Figure 3 As shown, the deep hole 121 is recessed inwardly along the axial direction of the feed barrel body 1 from the end surface of the tail portion 12 facing away from the head portion, and the oblique hole 122 is recessed inwardly from the outer surface of the tail portion 12 and communicates with the bottom of the deep hole 121. This makes the deep hole 121 and the oblique hole 122 of the tail portion 12 easy to process and manufacture.

[0043] In this embodiment, there are multiple deep holes 121 and multiple oblique holes 122. The oblique holes 122 are respectively connected to the multiple deep holes 121, and the deep holes 121 are used to connect to an external cooling device. The multiple deep holes 121 and multiple oblique holes 122 form cooling channels that can be distributed around the tail portion 12 and can achieve cooling and lowering temperature on all sides of the tail portion 12, greatly improving the cooling effect of the integrated feed barrel, achieving the advantages of long life and resistance to deformation of the integrated feed barrel, and at the same time making the injection process smoother, reducing downtime, and increasing production efficiency.

[0044] The tail portion 12 has a horizontal hole 123 recessed inward from the outer surface of the tail portion 12, allowing the multiple deep holes 121 to communicate through the horizontal hole 123. The horizontal hole 123 allows the multiple deep holes 121 to communicate with each other, allowing coolant to flow into different deep holes 121 for cooling, effectively enhancing the cooling effect. Furthermore, the horizontal hole 123 is easy to manufacture.

[0045] The integrated feed barrel also includes a plurality of plugs, which are plugged into the deep holes 121, the oblique holes 122, and the horizontal holes 123, so that only two deep holes 121 are unblocked and are used to communicate with an external cooling device, and a cooling channel is formed between the deep holes 121, the oblique holes 122, and the horizontal holes 123. Only two deep holes 121 are reserved in the tail portion 12 without being blocked, and the remaining deep holes 121 and all the oblique holes 122 and horizontal holes 123 are blocked by plugs, so that the external cooling device will be connected to the two unblocked deep holes 121, and the coolant provided by the external cooling device will flow into the cooling channel through one of the deep holes 121, and then will flow out through the other deep hole 121, thereby realizing the circulation of the coolant in the cooling channel, effectively enhancing the cooling effect of the tail portion 12. At the same time, only one cooling channel is formed between the deep hole 121, the oblique hole 122 and the horizontal hole 123, so that the overall length of this cooling channel is further increased, so that the coolant flow path in the tail 12 is longer, and the cooling effect is further enhanced.

[0046] In this embodiment, the number of deep holes 121 is four, and the four deep holes 121 include a first deep hole 1211, a second deep hole 1212, a third deep hole 1213 and a fourth deep hole 1214. The number of inclined holes 122 is two, one of which is connected to the first deep hole 1211 and the second deep hole 1212, and the other inclined hole 122 is connected to the third deep hole 1213 and the fourth deep hole 1214. The number of horizontal holes 123 is one, and one horizontal hole 123 is connected to the second deep hole 1212 and the third deep hole 1213. The first deep hole 1211 and the fourth deep hole 1214 are used to be connected to an external cooling device.

[0047] Two oblique holes 122 are located at a relatively far position from the end of the tail section 12 and are connected to the bottom of the first deep hole 1211, the second deep hole 1212, the third deep hole 1213, and the fourth deep hole 1214. A horizontal hole 123 is located at a relatively close position from the end of the tail section 12 and is connected to the middle area of ​​the second deep hole 1212 and the third deep hole 1213, so that the second deep hole 1212 and the third deep hole 1213 are connected. The first deep hole 1211 and the fourth deep hole 1214 serve as reserved coolant inlet and outlet interfaces and are used to connect to an external cooling device. The coolant enters the cooling channel through the first deep hole 1211, and then flows into the horizontal hole 123, the oblique hole 122, the second deep hole 1212, and the third deep hole 1213, and finally is discharged outward through the fourth deep hole 1214, so that the coolant circulates in the tail section 12, effectively enhancing the cooling effect of the tail section 12.

[0048] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
