Description

Technical Field

[0001] The utility model relates to the technical field of die-casting devices, in particular to a barrel structure manufactured by using a new double ion welding technology. Background Art

[0002] Die-casting molding devices are often used in die-casting enterprises of non-ferrous metals such as brass, aluminum and zinc alloy. The barrel of the die-casting machine is a key component. According to market feedback: the service life of the barrel is lower than the expected life. The main reason is that the barrel cavity at the pouring port and the cavity where the barrel and the mold are connected are easily corroded, the performance is reduced, and the service life is shortened. To solve this problem, most companies use higher-specification steel to form barrels, which leads to higher manufacturing and procurement costs and needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0004] The present application document discloses a barrel structure manufactured using a new dual ion welding technology, including a barrel body, a cavity arranged in the barrel body, two ends of the cavity correspondingly extending to the head and tail end faces of the barrel body, a pouring port is arranged on the peripheral wall of the barrel body near the head end and the pouring port is connected with the cavity, an inner lining layer 1 is arranged on the inner peripheral wall of the cavity at the position connected with the pouring port, and an inner lining layer 2 is arranged on the inner peripheral wall of the cavity opening at the tail end of the barrel body.

[0005] The structure is improved in the present scheme, and lining layer one and lining layer two are respectively formed on the inner wall of the cavity at the connection point of the pouring port and the inner wall of the cavity port at the tail end. The lining layers one and two refer to film layers formed with alloys and other materials, or film layers formed after corresponding process treatment. The performance of the formed film layers (such as wear resistance and corrosion resistance) is higher than the corresponding performance of the material of the barrel body. For example, the wear-resistant and corrosion-resistant alloy material is formed, or the lining layer is formed after strengthening process treatment. Targeted strengthening at the required position helps to increase the service life and reduce costs.

[0006] Preferably, the inner lining layer one and the inner lining layer two are formed by ion welding and ion nitriding treatment, such as forming a film layer at a predetermined position by ion welding with a predetermined type of welding wire, and then nitriding treatment is performed in an ion nitriding furnace to form the inner lining layer. The performance of the inner lining layer formed under this process is further improved.

[0007] Furthermore, the inner lining layer extends to the inner peripheral wall of the first end cavity opening of the barrel body, and the first end cavity opening is butted against the punch, which also helps to improve the service life.

[0008] Furthermore, a channel is provided in the cavity wall of the barrel body, one end of the channel is connected to the cavity and the other end extends to the outer wall of the barrel, and can be connected to an external vacuum device through the channel to perform vacuuming and other operations in the cavity.

[0009] Furthermore, the hole one is arranged adjacent to the material discharge port and is reasonably arranged to facilitate connection with an external mechanism.

[0010] Furthermore, a second channel is arranged in the cavity wall adjacent to the rear end of the barrel body and is arranged around the cavity. The inlet and outlet of the second channel are located at the end face or the outer wall of the head end of the barrel body. If cooling water is passed into the second channel to cool the cavity, the specific selection of the inlet and outlet positions facilitates docking with external mechanisms.

[0011] Furthermore, a second channel is arranged at intervals in the cavity wall between the middle and the tail end of the barrel body to improve the cooling effect.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model forms the inner lining layer at the required position, thereby increasing the service life of the barrel and strengthening the structure at the fixed point to help reduce costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 , Figure 2As shown, in this example, a barrel structure manufactured using the new technology of dual ion welding includes a columnar barrel body 1, a cavity is formed in the barrel body 1 along the axial direction, and the two ends of the cavity extend to the head and tail end faces of the barrel body 1 respectively, the cavity opening at the head end face is connected to the punch, and the cavity opening at the tail end face is connected to the mold gate sleeve. A pouring port 4 is formed on the peripheral wall of the barrel body near the head end, and the pouring port 4 is connected to the barrel cavity. This part of the structure is a common structure of the barrel and will not be repeated.

[0022] In this example, the inner lining layer 1 5 is formed on the inner circumferential wall of the cavity at the position connected to the pouring port 4, and the inner lining layer 2 7 is formed at the inner circumferential wall of the cavity opening at the tail end of the barrel body 1. The inner lining layer 1 and the inner lining layer 2 are preferably formed of alloy materials, and the film layer formed by the alloy material is formed into the inner lining layer after being treated by a strengthening process, such as double ion welding, first ion welding, and then ion nitriding. Specifically, if the welding wire is uniformly formed into a film layer at the inner circumferential wall of the cavity by an ion welding device, and then ion nitriding is performed in an ion nitriding furnace, the film layer formed after the treatment is the inner lining layer 1 or the inner lining layer 2, and the inner lining layer formed by double ion welding has excellent performance, which is stronger than the barrel body material, and has a fixed-point strengthening structure. There is no need to replace the barrel body material as a whole, which reduces costs and increases service life.

[0023] Of course, the thickness of lining layer 1 and lining layer 2 can be selected according to needs, and the coverage of lining layer 1 and lining layer 2 can be selected according to needs, such as lining layer 1 extending axially to the inner peripheral wall of the first end cavity opening of the barrel body 1.

[0024] In order to facilitate cooling of the material in the cavity, in this example, a second hole is formed in the cavity wall adjacent to the rear end of the barrel body 1. The second hole is formed around the cavity. For example, the second hole is in the shape of a ring, and the cavity of the barrel body passes through the ring mouth of the second hole. Multiple second holes can be selected, and the multiple second holes are distributed along the axial direction of the barrel body. The multiple second holes can share the same inlet and outlet, or each second hole exists independently and the inlet 2 and outlet 3 of the second hole are located at the end face or outer wall of the head end of the barrel body 1. Cooling water is passed into the second hole to cool the cavity. The number of second holes or the axial distribution length can be selected according to needs, such as Figure 1 As shown, the second channel is distributed at intervals in the cavity wall from the middle to the tail end of the barrel body 1.

[0025] In addition, a channel 6 can be formed in the cavity wall of the barrel body 1, such as a channel 6 formed near the pouring port 4. The channel extends radially, one end of the channel is connected to the cavity and the other end extends to the outer wall of the barrel. The channel can be connected to an external vacuum device through the channel to perform vacuuming and other operations in the cavity.

[0026] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
