Description

Technical Field

[0001] This invention relates to the field of die-casting mold technology, specifically to a die-casting mold for automotive end caps. Background Technology

[0002] In the automotive manufacturing industry, automotive end caps, as important components, play a crucial role in protecting the internal structure, sealing, and assisting in the normal operation of related parts. With the continuous development of the automotive industry, higher requirements have been placed on the quality, precision, and production efficiency of automotive parts. Die casting technology, with its advantages of efficiently producing parts with complex shapes, high dimensional accuracy, and good mechanical properties, is widely used in the manufacturing process of automotive end caps. Accordingly, die casting molds have become one of the core equipment for achieving high-quality automotive end cap production. Existing die casting molds typically consist of a moving mold, a moving template, a fixed mold, and a fixed template. In use, the moving mold and moving template are fixedly installed on the moving template of the die casting machine, and the fixed mold and fixed template are fixedly installed on the fixed template of the die casting machine. Then, the die casting machine is started to close the fixed mold and the moving mold. Next, molten metal is poured into the mold cavity between the fixed mold and the moving mold through the casting pipe. After the molten metal has solidified and cooled, the die casting machine is started again to separate the fixed mold and the moving mold. Finally, the formed product can be removed.

[0003] The existing gating system of die casting molds mostly adopts the more conventional straight gating or side gating. Although this can meet the basic requirements of molten metal filling, the gating is usually fixed and cannot be adjusted. Its flexibility is poor and it is easy to have uneven molten metal flow, resulting in defects such as air entrapment and inclusions in the end cap, which affects the overall performance of the product and greatly reduces the working efficiency and quality of die casting molds to a certain extent.

[0004] Therefore, a die-casting mold for automotive end caps was proposed to solve the above problems. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a die-casting mold for automotive end caps, comprising the following features:

[0019] Beneficial effects:

[0020] 1. This invention utilizes a flow channel adjustment assembly, including a motor, to adjust the flow channel according to the casting requirements of the end cap. The motor activates an electric telescopic rod to push a connecting plate to slide the sleeve on the outer wall of the flow tube. Simultaneously, the motor rotates a threaded screw, causing the connecting plate to move horizontally, which in turn moves a push rod to move with the sleeve, ensuring the push block remains within the inner wall of one end of the sleeve. Molten metal is then poured into the funnel, flowing into the sleeve. The motor is then activated again, causing the push rod to push the push block to slide, pushing the molten metal from the inner wall of the sleeve towards the flow tube. When the molten metal reaches the inner wall of the runner, the electric telescopic rod 1 is activated, causing the push rod 2 to slide. This allows the push block 2 to slide along the inner wall of the runner, pushing the molten metal into the closed mold cavity. Utilizing the above structure, by activating the electric telescopic rod 2, the electric telescopic rod 1, and the motor 1, not only is the length of the runner adjusted, but the flow rate of the molten metal within the runner is also controlled. This improves the flexibility of the mold runner, ensuring that the molten metal can smoothly, evenly, and quickly fill the entire cavity, avoiding die-casting defects such as incomplete filling and cold shuts, thus guaranteeing the overall performance of the product and greatly improving the working efficiency and quality of the die-casting mold.

[0021] 2. This invention utilizes a uniform cooling assembly, including a cooling tank. During cooling, a water pump is activated to deliver cooling water from the cooling tank to the interior of the U-shaped cooling pipe via a first hose, and then back to the cooling tank via a second hose. Simultaneously, a second motor is activated to rotate a reciprocating screw. The rotation of the reciprocating screw causes the fixed block connected to its outer surface to slide, thereby causing the mounting block to slide, which in turn causes the U-shaped cooling pipe to reciprocate on one side of the moving mold. Utilizing the above structure, by activating the second motor to drive the U-shaped cooling pipe to reciprocate on one side of the moving mold, the cooling effect of the mold is achieved, accelerating product production efficiency. Furthermore, the movement speed of the U-shaped cooling pipe can be controlled by adjusting the rotation speed of the second motor, allowing the U-shaped cooling pipe to move slower or faster on the thicker or thinner side of the product, ensuring uniform cooling of the product and further improving the production efficiency and quality of the die-casting mold.

[0022] 3. The present invention uses a buffer assembly, including a connecting rod, which is slidably installed on the inner walls of the fixed plate and the moving plate. Then, threaded sleeves are threaded to the outer walls of both ends of the connecting rod. When the mold is closed, the two buffer rings on the outer wall of the connecting rod fit together and compress the spring. Using the above structure, the buffer rings and springs achieve a buffering effect when the mold is closed, reducing the wear of the fixed mold and the moving mold during closure and improving the service life of the mold to a certain extent.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0033] Example

[0034] Please refer to Figures 1 to 6 As shown:

[0035] To address the problems mentioned in the technical solutions, this application provides a die-casting mold for automotive end caps, comprising a base plate 1, a movable plate 9 and a fixed plate 5 slidably mounted on the upper outer surface of the base plate 1, a fixed mold 6 fixedly mounted on one outer surface of the fixed plate 5, a support plate 7 fixedly mounted on the other outer surface of the fixed plate 5, a movable mold 10 fixedly mounted on one outer surface of the movable plate 9, a protective frame 8 fixedly mounted on the other outer surface of the movable plate 9, a flow channel adjustment component 2 provided on one side of the fixed mold 6, a uniform cooling component 3 provided on one side of the movable mold 10, and a buffer component 4 provided between the movable plate 9 and the fixed plate 5;

[0036] The flow channel adjustment assembly 2 includes a motor 21. A threaded screw 22 is fixedly installed on the outer surface of the output end of the motor 21. A connecting plate 23 is threadedly connected to the outer surface of the threaded screw 22. A push rod 24 is fixedly installed on one side of the outer surface of the connecting plate 23. A push block 25 is fixedly installed on one end of the outer surface of the push rod 24. A sleeve 26 is slidably installed on the outer wall of the push block 25. A funnel 27 is fixedly installed on the upper outer surface of the sleeve 26. A flow tube 28 is slidably installed on the inner wall of the sleeve 26. An electric telescopic rod 29 is fixedly installed on one side of the inner wall of the push rod 24. A push rod 211 is fixedly installed on the outer surface of the telescopic end of the electric telescopic rod 29. A push block 212 is fixedly installed on the outer surface of one end of the push rod 211. A connecting plate 213 is fixedly installed on the outer wall of the sleeve 26. An electric telescopic rod 214 is fixedly installed on one side of the outer surface of the connecting plate 213.

[0037] Preferably, motor 21 is fixedly installed on the upper outer surface of support plate 7, flow tube 28 is fixedly installed on one side outer surface of fixed mold 6, push rod 211 slides on the inner wall of push rod 24 and push block 25, and electric telescopic rod 214 is fixedly installed on one side inner wall of fixed plate 5.

[0038] By activating the electric telescopic rod 214, the connecting plate 213 is pushed, causing the sleeve 26 to slide on the outer wall of the flow tube 28. Simultaneously, the motor 21 is activated, driving the threaded screw 22 to rotate. The rotation of the threaded screw 22 causes the connecting plate 23, which is threaded to its outer surface, to move horizontally, causing the push rod 24 to move with the sleeve 26. This ensures that the push block 25 remains within one end of the inner wall of the sleeve 26. Then, the molten metal is poured into the funnel 27, allowing it to flow into the sleeve 26. Next, the motor 21 is activated again, causing the push rod 24 to push the push block 25 to slide. The molten metal inside the sleeve 26 is pushed to the inner wall of the flow tube 28. At this time, the electric telescopic rod 29 is activated to drive the push rod 211 to slide, so that the push block 212 slides on the inner wall of the flow tube 28, pushing the molten metal into the closed mold cavity. This not only realizes the adjustment of the length of the gating, but also realizes the control of the flow rate of the molten metal in the gating, which improves the flexibility of the mold gating, ensures that the molten metal can fill the entire cavity smoothly, evenly and quickly, avoids die casting defects such as incomplete filling and cold shut, and ensures the overall performance of the product, thereby greatly improving the working efficiency and quality of the die casting mold.

[0039] Preferably, the uniform cooling assembly 3 includes a cooling box 31, a water pump 32 is fixedly installed on one outer surface of the cooling box 31, a hose 33 is fixedly installed on one outer surface of the water pump 32, a U-shaped cooling pipe 34 is fixedly connected to one end of the hose 33, a hose 35 is fixedly connected to one end of the U-shaped cooling pipe 34, an installation block 36 is fixedly sleeved on the outer wall of the U-shaped cooling pipe 34, a fixing block 37 is fixedly installed on one outer surface of the installation block 36, a reciprocating screw 38 is threadedly connected to the inner wall of the fixing block 37, and a motor 39 is fixedly installed on the outer surface of one end of the reciprocating screw 38.

[0040] Preferably, the cooling box 31 is fixedly installed on the lower outer surface of the base plate 1, one end of the second hose 35 is fixedly connected to the water inlet surface of the cooling box 31, the first hose 33 and the second hose 35 are both set on the lower inner wall of the moving plate 9, the mounting block 36 slides on the surface between the moving plate 9 and the moving mold 10, the fixing block 37 slides on the inner surface of the protective frame 8, the reciprocating screw 38 is rotatably connected to the inner wall of the protective frame 8, and the second motor 39 is fixedly installed on one side inner wall of the protective frame 8.

[0041] By starting the water pump 32, the cooling water in the cooling tank 31 is transported to the interior of the U-shaped cooling pipe 34 through the first hose 33, and then flows back to the cooling tank 31 through the second hose 35. At the same time, the second motor 39 is started to drive the reciprocating screw 38 to rotate. The rotation of the reciprocating screw 38 causes the fixed block 37 connected to its outer surface to slide, thereby causing the mounting block 36 to slide, and then causing the U-shaped cooling pipe 34 to slide back and forth on one side of the moving mold 10, realizing the cooling effect of the mold and accelerating the production efficiency of the product. At the same time, the moving speed of the U-shaped cooling pipe 34 can be controlled by controlling the speed of the second motor 39, so that the moving speed of the U-shaped cooling pipe 34 is slower or faster on the thicker or thinner side of the product, ensuring uniform cooling of the product and further improving the production efficiency and quality of the die-casting mold.

[0042] Preferably, the buffer assembly 4 includes a connecting rod 41, with two fixed threads 42 symmetrically arranged on the outer walls of both ends of the connecting rod 41. Two threaded sleeves 43 are threadedly connected to the outer surfaces of the two fixed threads 42. Two buffer rings 44 are symmetrically slidably installed on the outer walls of the connecting rod 41. Two springs 45 are fixedly installed on one side of the outer surface of each of the two buffer rings 44.

[0043] Preferably, the connecting rod 41 is slidably mounted on the inner wall of the fixed plate 5 and the moving plate 9, one threaded sleeve 43 is attached to one side of the outer surface of the fixed plate 5, another threaded sleeve 43 is attached to one side of the outer surface of the moving plate 9, one end of a spring 45 is attached to the other side of the outer surface of the fixed plate 5, and one end of another spring 45 is attached to the other side of the outer surface of the moving plate 9.

[0044] With the buffer rings 44 and springs 45 in place, when the mold is closed, the two buffer rings 44 on the outer wall of the connecting rod 41 fit together and squeeze the springs 45 at the same time, which realizes the buffering effect when the mold is closed, reduces the wear of the fixed mold 6 and the moving mold 10 when they close, and improves the service life of the mold to a certain extent.

[0045] Preferably, the inner diameter of the flow tube 28 is equal to the diameter of the pusher block 212, and the actuating pusher rod 24 causes the pusher block 212 to slide on the inner wall of the flow tube 28.

[0046] Preferably, when the fixed mold 6 and the moving mold 10 are closed, the two buffer rings 44 fit together and the two springs 45 are compressed.

[0047] The working principle of all the content in the above embodiments is as follows:

[0048] First, the fixed plate 5 is fixedly installed on the fixed mold plate of the die-casting machine, and the moving plate 9 is fixedly installed on the moving mold plate of the die-casting machine. Then, according to the casting requirements of the end cap, the electric telescopic rod 214 is activated to push the connecting plate 213 to drive the sleeve 26 to slide on the outer wall of the flow tube 28. At the same time, the motor 21 is activated to drive the threaded screw 22 to rotate. The rotation of the threaded screw 22 causes the connecting plate 23 with its outer threaded connection to move horizontally, which drives the push rod 24 to move with the sleeve 26, so that the push block 25 is always on the inner wall of one end of the sleeve 26. In use, the die-casting machine is activated to drive the moving mold 10 to approach the fixed mold 6 and complete the closure. When closed, the two buffer rings 44 on the outer wall of the connecting rod 41 are in contact with each other and simultaneously compress the spring 45. Using the above structure, the buffer rings 44 and the spring 45 are set to achieve the buffering effect when the mold is closed. This reduces wear during the closing of the fixed mold 6 and the moving mold 10. After closing, molten metal is poured into the funnel 27, allowing it to flow into the sleeve 26. Then, motor 21 is restarted, causing push rod 24 to push push block 25 to slide, pushing the molten metal on the inner wall of sleeve 26 to the inner wall of flow tube 28. At this time, electric telescopic rod 29 is activated, driving push rod 211 to slide, causing push block 212 to slide on the inner wall of flow tube 28, pushing the molten metal into the closed mold cavity. This achieves the adjustment of the runner length and the control of the molten metal flow rate within the runner, improving the flexibility of the mold runner and ensuring that the molten metal can fill the entire cavity smoothly, evenly, and quickly. This avoids die-casting defects such as incomplete filling and cold shuts, ensuring the overall performance of the product and greatly improving the working efficiency and quality of the die-casting mold.

[0049] During cooling, the water pump 32 is started to deliver cooling water from the cooling tank 31 to the interior of the U-shaped cooling pipe 34 through the first hose 33, and then back to the cooling tank 31 through the second hose 35. At the same time, the second motor 39 is started to drive the reciprocating screw 38 to rotate. The rotation of the reciprocating screw 38 causes the fixed block 37 connected to its outer surface to slide, thereby causing the mounting block 36 to slide, and then causing the U-shaped cooling pipe 34 to slide back and forth on one side of the moving mold 10, completing the rapid cooling of the mold and accelerating the production efficiency of the product. At the same time, the moving speed of the U-shaped cooling pipe 34 can be controlled by controlling the speed of the second motor 39, so that the moving speed of the U-shaped cooling pipe 34 is slower or faster on the thicker or thinner side of the product, ensuring uniform cooling of the product and further improving the production efficiency and quality of the die-casting mold. After cooling is completed, the die-casting machine is started to separate the fixed mold 6 and the moving mold 10, and finally the product can be removed.
