Description

Technical Field

[0001] This utility model relates to the field of molding equipment technology, specifically to a corrosion-resistant cylinder for an injection chamber with intelligent temperature control. Background Technology

[0002] The widespread application of magnesium-aluminum alloy products, coupled with the emergence of large-scale integrated die-casting technology, has enabled the production of multiple products into a single process. Consequently, the technical requirements for injection chambers in integrated molds are gradually increasing, as are the requirements for injection barrels.

[0003] In a conventional die casting cylinder, molten metal, such as aluminum liquid, is poured into the inlet. The injection head then pushes the molten metal through the inlet cavity into the die cylinder, filling it completely. Under the action of the injection rod, the casting pressure increases, forcing the molten metal along the mold's flow cone into the mold cavity, thus completing the die casting process. The injection end of the cylinder is the area with the most concentrated heat. The bottom of the cylinder inlet is highly susceptible to erosion due to thermal deformation, producing residue. This residue can also cause scratches on the inner wall of the cylinder during the injection head's movement, affecting the cylinder's service life.

[0004] Traditional cooling methods for this issue involve drilling holes in the cylinder body. However, this often leads to cylinder cracking and leaks due to thermal stress, significantly increasing repair costs. Current common cooling methods include installing cooling circulation pipes inside the cylinder wall, but these are ineffective and require improvement. Utility Model Content

[0005] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0006] This application discloses a corrosion-resistant injection chamber barrel with intelligent temperature control, comprising a cylindrical body and an insert. The insert has a cylindrical body and a fixed end at its end. The cylindrical body is located in the cavity at the front end of the body and its rear end cavity is connected to the material cavity of the body. An inlet hole is formed on the peripheral wall of the cylindrical body corresponding to the inlet on the peripheral wall at the front end of the body and is connected to the cavity. A circulation pipe for coolant flow is provided on the peripheral wall of the cylindrical body, and the outlet and inlet of the circulation pipe are both located at the fixed end. The fixed end is located outside the cavity at the front end of the body and is fixed to the front end of the body.

[0007] When in use, molten aluminum enters the cylinder cavity through the feed port. Cold water is used as the coolant and is introduced into the circulation pipeline. The flow of cold water cools the inner wall of the cylinder. The single-directional cooling method greatly reduces the erosion rate of the inner wall of the cylinder by the molten aluminum, thereby increasing the service life of the cylinder and greatly avoiding cracking and leakage of the material cavity.

[0008] Furthermore, multiple sets of circulation pipes are arranged inside the cavity wall of the main body. These multiple sets of circulation pipes surround the material cavity of the main body and can be used for cooling with circulation pipes one and two as needed, making it more convenient to use.

[0009] Furthermore, the inlet and outlet of the second circulation pipeline are located at fixed ends to facilitate liquid inflow and outflow.

[0010] Furthermore, a vacuum hole is provided on the peripheral wall of the main body, and the vacuum hole is connected to the material cavity behind the inner cylinder of the insert, thereby increasing the vacuum hole to facilitate gas extraction.

[0011] Furthermore, a water jacket is fitted at the tail end of the main body, and a circulation pipe three is provided on the peripheral wall of the main body within the water jacket cavity. A cooling inlet and a cooling outlet connected to the circulation pipe three are provided on the peripheral wall of the water jacket. The circulation pipe three is added to facilitate cooling or temperature control, and the cooling inlet and outlet are provided on the peripheral wall to facilitate the input and output of coolant.

[0012] Furthermore, the inner diameter of the cylinder is the same as the inner diameter of the material cavity of the main body, and the outer diameter of the water jacket is smaller than the outer diameter at the beginning of the main body.

[0013] Furthermore, a fixing block is provided on the inner wall of the cavity at the first end of the main body, and the fixing block is partially located in the positioning hole formed on the peripheral wall of the cylinder. Adding the fixing block helps to improve the stability of the cylinder in the insert.

[0014] Furthermore, the fixed end is ring-shaped, which facilitates connection with the end face of the body.

[0015] Furthermore, it also includes a refrigeration system and a temperature sensor. A temperature sensor is installed at the outlet of the first circulation pipeline, and the outlet and inlet of the first circulation pipeline are connected to the refrigeration system. If the temperature sensor detects the water temperature at the outlet, the refrigeration system will start accordingly after receiving the signal to cool the water, thereby cooling the inner wall of the cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model improves the structure of the barrel. The barrel body in the insert has a circulation pipeline, which can reduce the temperature of the inner wall of the barrel in a single direction, thereby reducing the corrosion of the inner wall by high-temperature aluminum liquid and helping to improve the service life of the barrel.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] like Figure 1 , Figure 2 As shown, in this example, a corrosion-resistant injection chamber barrel with intelligent temperature control includes a cylindrical body 1 and an insert 2. The insert 2 has a cylindrical body 22 and a fixed end 21 at its end. The fixed end 21 is, for example, a common ring shape, and is fixed to the end face of the cylindrical body 22 by screws or the like. The cylindrical body is made of a wear-resistant and corrosion-resistant alloy, such as titanium alloy. A groove is formed on the peripheral wall of the cylindrical body 22, and a circulation pipe 24 for coolant flow is installed in the groove. Figure 2 As shown, the circulation pipe 24 extends continuously in an S-shape. When in use, if cold water is used as the coolant, the cylinder is cooled by the flow of cold water in the circulation pipe 24.

[0028] The inlet 26 and outlet 25 of the circulation pipe 24 are both located at the end face of the fixed end 21, which facilitates connection with external systems such as refrigeration systems. Preferably, the circulation pipe 24 is located directly below the feed hole 23, which can provide directional cooling for the impact point of the molten aluminum.

[0029] like Figure 1 , Figure 2 , Figure 3As shown, the insert 2 has a cylindrical body 22 located in the opening at the front end of the main body 1. The peripheral wall of the cylindrical body 22 fits the corresponding cavity wall, and the inner diameter of the cylindrical body 22 is the same as the inner diameter of the material cavity of the main body 1. The opening at the rear end of the cylindrical body 22 is connected to the material cavity of the main body 1, and the opening at the front end of the cylindrical body 22 is directly opposite to the opening at the front end of the main body 1. An inlet hole 23 is formed on the peripheral wall of the cylindrical body 22 corresponding to the inlet 3 on the peripheral wall of the front end of the main body 1, which is connected to the inside of the cylindrical cavity. The aluminum liquid enters from the inlet on the peripheral wall of the main body and enters the cylindrical cavity of the cylindrical body through the inlet hole. The injection rod extending from the opening at the front end of the cylindrical body pushes the aluminum liquid out from the opening at the rear end of the main body.

[0030] In this example, the fixed end 21 is located outside the cavity of the first end of the body 1 and is fixed to the end face of the first end of the body 1, such as by screws, bolts, etc., to fix the fixed end to the end face of the first end of the body.

[0031] To improve stability, a groove is formed on the inner wall of the first end cavity of the main body 1 in this example. A fixing block 6 is installed in the groove by screws or the like. The top of the fixing block 6 is in the positioning hole formed on the peripheral wall of the cylinder. The stability of the cylinder is improved by the limiting of the fixing block.

[0032] In this example, multiple sets of circulation pipes (II) are formed within the cavity wall of the main body 1. These II circulation pipes can be S-shaped or trough-shaped, depending on the requirements. The number of II circulation pipes can also be selected according to requirements, such as 2 sets or 3 sets. These multiple sets of II circulation pipes are arranged around the material cavity of the main body to cool the main body. The placement and forming of the II circulation pipes can refer to conventional techniques and will not be elaborated further. The inlet and outlet of the II circulation pipes are also located at the fixed end face for convenient liquid inlet and outlet.

[0033] like Figure 1 , Figure 4 As shown, a cylindrical water jacket 5 is fitted at the tail end of the main body 1, and a circulation pipe 3 7 is installed on the periphery of the main body 1 inside the cavity of the water jacket 5. The circulation pipe 3 extends in an S-shaped or similar configuration. The circulation pipe 3 7 extends around the periphery of the tail end of the main body. A cooling inlet 51 and a cooling outlet 52 connected to the circulation pipe 3 7 are formed on the periphery of the water jacket 5, which facilitates cooling or temperature control of the barrel.

[0034] like Figure 1 As shown, a vacuum hole 4 is formed on the peripheral wall of the main body 1. The vacuum hole 4 is connected to the material cavity behind the cylinder 22 in the insert 2, and the vacuum hole is added to facilitate gas extraction. In order to facilitate docking with external equipment, the outer diameter of the tail end of the main body 1 is smaller than the outer diameter of the head end of the main body in this example, and the outer diameter of the water jacket 5 is also smaller than the outer diameter of the head end of the main body.

[0035] When this material cylinder is used in conjunction with a refrigeration system and a temperature sensor, such as a common circulating water chiller, a temperature sensor is installed at the outlet of the first circulation pipe. The temperature sensor is connected to the control terminal of the refrigeration system. The outlet and inlet of the first circulation pipe are connected to the corresponding water outlet and inlet of the refrigeration system. When in use, if the temperature sensor detects the water temperature at the outlet of the first circulation pipe, the refrigeration system will start accordingly after receiving the temperature sensor data to cool the water, thereby cooling the inner wall of the cylinder and reducing phenomena such as aluminum molten corrosion.

[0036] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
