Description

Technical Field

[0001] The utility model relates to the technical field of die-casting processing, in particular to a combined barrel. Background Art

[0002] The die-casting machine includes an injection cavity and a die-casting feed barrel. The injection cavity is located in the die-casting feed barrel, and the die-casting feed barrel extends into the product cavity. The molten metal enters the product cavity through the injection cavity to complete the casting.

[0003] In the barrel of the prior art, one end of the barrel for die casting is in frequent contact with the high-temperature casting liquid, which will cause the barrel to be deformed or tilted after a long time. However, under normal circumstances, the barrel is usually directly replaced after a certain service life. However, after observation, the operator found that generally only the surface of the barrel that is in direct contact with the casting liquid will be damaged, so a lot of material will be wasted. For this reason, we urgently need a die-casting barrel of corresponding material that can be replaced. Utility Model Content

DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1 、 Figure 2 and Figure 3As shown, a combined barrel comprises a first barrel base 1 and a second barrel base 2, the end face of the second barrel base 2 is integrally connected to the end face of one end of the first barrel base 1, and a ring-shaped cooling water channel 3 is provided on the circumferential outer wall of the second barrel base 2, and an iron ring 4 is fixedly connected to the bottom wall of the cooling water channel 3, and the iron ring 4 divides the cooling water channel 3 into a first cooling water channel 5 and a second cooling water channel 6, and the iron ring 4 is provided with a notch 7 for allowing the first cooling water channel 5 and the second cooling water channel 6 to communicate with each other, and a third barrel base 8 is also fixedly sleeved on the second barrel base 2; it also includes a barrel bushing 9, an annular groove 10 is provided on the inner wall of one end of the second barrel base 2, and an internal thread 11 is provided on the inner wall of the annular groove 10, and an external thread 12 is provided on the circumferential outer wall of the barrel bushing 9, the barrel bushing 9 is screwed into the first barrel base 1, and an inlet 13 is provided on one side of the first barrel base 1.

[0017] In actual operation, when the operator needs to replace the bushing in the barrel, first, the operator takes out the barrel, then rotates the barrel bushing 9, and rotates the barrel bushing 9 to the outside of the second barrel base 2, and then processes the replaced barrel in the propulsion device. The cooling water channel 3 provided on the second barrel base 2 can cool the barrel while it is being processed, thereby reducing the damage to the barrel due to long-term contact with the high-temperature casting liquid during processing.

[0018] The second barrel base 2 provided can increase the processing area of ​​contact between the barrel and the high-temperature casting liquid, the third barrel base 8 provided can cooperate with the second barrel base 2 to form cooling for the barrel, and the barrel bushing 9 provided can be replaced in time if it is damaged after long-term processing, thereby increasing processing efficiency, and the high-temperature casting liquid can be filled and processed through the provided feed port 13, and the second barrel base 2 and the third barrel base 8 are integrally formed to prevent excess cooling water from leaking from between the second barrel base and the third barrel base 8.

[0019] like Figure 1 、 Figure 2 and Figure 3 As shown, the outer diameter of the iron ring 4 is the same as the inner diameter of the third barrel base 8. The inner wall of the barrel bushing 9 after being screwed into the first barrel base 1 is flush with the inner walls of the first barrel base 1 and the second barrel base 2. A water inlet hole 14 and a water outlet hole 15 are respectively provided on the third barrel base 8, and the water inlet hole 14 is connected to the first cooling water channel 5, and the water outlet hole 15 is connected to the second cooling water channel 6.
