Description

Technical Field

[0001] The present application relates to the technical field of metal processing, and in particular to an anti-wear buffer structure of a die-casting mold and a die-casting mold. Background Art

[0002] At present, in the die-casting industry, the common method is to use a cylinder to drive the movable die to move and close the mold with the fixed die to complete the part forming process. This process is widely used in large-scale batch production of various complex-shaped metal products due to its high efficiency and speed, which not only improves production efficiency but also reduces costs.

[0003] However, in existing die-casting equipment, the movable mold is usually directly pushed by the slider on the cylinder, so that the movable mold and the fixed mold are precisely connected to form a closed cavity. Due to the strong driving force of the cylinder, the movable mold will generate a strong impact force when it moves to the predetermined position at high speed and contacts the fixed mold. Long-term and repeated impact force will cause the mold to deform or even damage. Existing die-casting equipment usually adds a spring between the cylinder and the movable mold to absorb the impact force through the spring to reduce the stress on the movable mold. However, the effect of the spring absorbing the impact force is still far from meeting the requirements of smooth transition. Summary of the invention

[0048] The present application also discloses a die-casting mold. Figure 2 and Figure 3 The die-casting mold includes a fixed mold 6, a movable mold 7, a first limit plate 83, a second limit plate 84, a connecting plate 86, a third limit plate 85, an anti-wear buffer structure of the die-casting mold and a clamping valve 9.

[0049] like Figure 2 and Figure 3 As shown, the movable mold 7 and the fixed mold 6 are arranged opposite to each other, and a driving component 8 is arranged at one end of the movable mold 7 away from the fixed mold 6. The driving component 8 is used to drive the movable mold 7 to move linearly so that the movable mold 7 is close to or away from the fixed mold 6. The anti-wear buffer structure of the die-casting mold is detachably arranged at one end of the movable mold 7 close to the driving component 8, and is used to absorb the impact force exerted on the movable mold 7 when the movable mold 7 contacts the fixed mold 6, so as to reduce the stress exerted on the movable mold 7.

[0050] like Figure 4 and Figure 5 As shown, the first limiting plate 83 is arranged between the first pouch 1 and the second pouch 2, and the two sides of the first limiting plate 83 are detachably connected to the first pouch 1 and the second pouch 2 respectively by adhesive, and two through holes are provided on the first limiting plate 83 for two connecting tubes 4 to pass through. The first limiting plate 83 is fixedly connected to the driving component 8 on one side close to the second pouch 2, so that the driving component 8 can drive the first limiting plate 83 to move, thereby changing the positions of the first pouch 1 and the second pouch 2.

[0051] In the embodiment of the present application, the first limiting plate 83 is specifically a metal plate; the first limiting plate 83 can ensure that the positions of the first bag 1 and the second bag 2 in the die-casting mold are fixed to prevent displacement under high pressure and impact; the first limiting plate 83 is fixedly connected to the driving component 8, so that under the drive of the driving component 8, the first limiting plate 83 can move, thereby changing the positions of the first bag 1 and the second bag 2, so as to facilitate driving the module to move; optionally, the two connecting tubes 4 are detachably connected to the corresponding through holes by adhesive.

[0052] like Figure 4 and Figure 5As shown, the second limiting plate 84 is fixedly connected to the driving assembly 8 , and the second limiting plate 84 is used to jointly squeeze the second pouch 2 when the first limiting plate 83 moves, so that the filling liquid 32 in the second pouch 2 moves into the first pouch 1 , thereby changing the size of the first pouch 1 .

[0053] Specifically, in the embodiment of the present application, the driving assembly 8 is a two-section electric push rod, including a first telescopic rod 81 and a second telescopic rod 82. The first telescopic rod 81 and the second telescopic rod 82 are both driven by a motor. The first telescopic rod 81 is slidably connected to the second telescopic rod 82. The end of the first telescopic rod 81 away from the second telescopic rod 82 is fixedly connected to the first limit plate 83 to drive the first limit plate 83 to move when the first telescopic rod 81 moves relative to the second telescopic rod 82. The second telescopic rod 82 passes through the second limit plate 84, and the second telescopic rod 82 is fixedly connected to the second limit plate 84 to drive the second limit plate 84 to move when the second telescopic rod 82 moves.

[0054] like Figure 4 and Figure 5 As shown, the connecting plate 86 is slidably connected to the movable mold 7 and the first limit plate 83, and the connecting plate 86 is fixedly connected to the second limit plate 84 to limit the position of the movable mold 7, the first limit plate 83 and the second limit plate 84, so that the movable mold 7, the first limit plate 83 and the second limit plate 84 are tightly connected together to form a stable whole; the connecting plate 86 allows relative sliding movement between the movable mold 7 and the first limit plate 83, while ensuring that the position of the second limit plate 84 is fixed, thereby adapting to dynamic changes in the die-casting process.

[0055] In an embodiment of the present application, two connecting plates 86 are provided, and the two connecting plates 86 are respectively arranged on both sides of the structure formed by connecting the movable mold 7, the first limiting plate 83 and the second limiting plate 84. The two connecting plates 86 are slidably connected to the movable mold 7 and the first limiting plate 83 through corresponding sliding rails.

[0056] There are two third limiting plates 85, which are respectively fixed on the top and bottom of the two connecting plates 86 to limit the position of the first bag 1 and the second bag 2 together with the two connecting plates 86 and the second limiting plate 84, ensuring that the first bag 1 and the second bag 2 maintain position stability during the die-casting process, reducing the vertical displacement of the first bag 1 and / or the second bag 2 due to pressure or impact force, thereby ensuring the stability and effectiveness of the die-casting mold.

[0057] like Figure 5 and Figure 6As shown, in the embodiment of the present application, two clamp valves 9 are provided, each of which includes a working end and an operating end. The operating end of each clamp valve 9 is provided on a side of the third limiting plate 85 away from the two connecting plates 86. The working end of each clamp valve 9 passes through the third limiting plate 85 and is respectively connected with the corresponding connecting pipe 4 and the corresponding second bag 2; the cross-sectional area of ​​the working end can be changed by the operating end of the clamp valve 9, thereby changing the flow rate of the filling liquid 32, and then adjusting the pressure range of the first bag 1, thereby ensuring that the anti-wear buffer structure of the die-casting mold is maintained on a stable horizontal line.

[0058] Optionally, in the embodiment of the present application, a through groove for the pinch valve 9 to move is formed on the third limiting plate 85 .

[0059] Specifically, the first telescopic rod 81 of the driving assembly 8 is extended to drive the first bag 1 to move in the direction of the fixed mold 6, thereby driving the movable mold 7 to move in the direction of the fixed mold 6 and contact with the fixed mold 6. When the movable mold 7 contacts with the fixed mold 6, an impact force is generated, and the movable mold 7 transfers the impact force to the first bag 1. The first bag 1, the elastic material 31 and the filling liquid 32 can directly absorb the impact force through deformation and flow. The second bag 2 can be deformed by the flowing filling liquid 32, thereby assisting the first bag 1 to absorb the impact force, and then absorb the impact force generated when the movable mold 7 contacts with the fixed mold 6, reducing the stress on the movable mold 7; the extension of the second telescopic rod 82 of the driving assembly 8 can drive the connecting plate 86 to move in the direction of the fixed mold 6, thereby driving the movable mold 7 to approach the fixed mold 6 and contact with the fixed mold 6, ensuring that the movable mold 7 can abut against the fixed mold 6.

[0060] When the first telescopic rod 81 drives the movable mold 7 to continue moving in the direction of the fixed mold 6, the first bag 1 and the elastic material 31 further absorb the impact force through deformation. After the first bag 1 is deformed, the filling liquid 32 flows into the second bag 2. The flow of the filling liquid 32 and the deformation of the second bag 2 further absorb the impact force, further absorbing the impact force generated when the movable mold 7 contacts the fixed mold 6, reducing the stress on the movable mold 7, and improving the problem of strong impact force generated when the existing movable mold 7 contacts the fixed mold 6.

[0061] When the die-casting is completed, the second telescopic rod 82 is driven to reset by the driving component 8 to separate the movable mold 7 and the fixed mold 6. At this time, the first telescopic rod 81 is driven to reset by the driving component 8 to drive the first limit plate 83 away from the movable mold 7. After the first limit plate 83 is away from the movable mold 7, it and the second limit plate 84 squeeze the second bag 2 together, which can drive the filling liquid 32 in the second bag 2 to flow into the first bag 1. At the same time, the elastic material 31 in the first bag 1 recovers and drives the first bag 1 to recover, thereby completing the reset of the die-casting mold.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
