Description

Technical Field

[0001] This invention relates to the field of die casting technology, specifically to a die casting mold for die casting parts with inserts for new energy vehicles. Background Technology

[0002] In some automotive parts, inserts need to be placed inside the die-cast parts, depending on the design requirements.

[0003] Chinese Patent Publication No. CN105149546B discloses a composite inclined core-pulling ejection mechanism for a zinc alloy die-casting mold of a car center knob. The mechanism includes a fixed mold core mounted on a fixed mold plate, a movable mold core mounted on a movable mold plate, and a stripper plate. The fixed mold plate, movable mold plate, and stripper plate are sequentially connected by guide pillars. An inclined core-pulling device is installed within the cavity of the stripper plate and the movable mold plate, with the bottom end of the inclined core-pulling device connected to the stripper plate. An insert support plate is mounted on the movable mold core and fitted onto the inclined core-pulling device. Forming ejection inserts and forming inclined cores are sequentially spaced around the inclined core-pulling device on the insert support plate. The forming ejection inserts abut against the outer periphery of the car center knob, and the forming inclined cores abut against the groove of the car center knob.

[0004] Because die-cast parts with inserts usually have a complex structure, special mold design is required when die-casting them to ensure that the inserts are placed in the die-casting mold before die-casting. There is a type of automotive die-cast part with inserts that requires the inserts to be suspended during die-casting, but there is no suitable die-casting mold for this type of part in the existing technology.

[0015] Preferably, a second forming rod is also provided on the moving mold core. When the mold is closed, the end faces of the fixed mold core and the moving mold core that are in contact with each other are called reference end faces. The reference end faces are in a vertical state. The plane formed by the second forming rod and the insert is parallel to the reference end face, and one end of the second forming rod abuts against the forming column.

[0016] Preferably, after the insert is fixed by the fixing component, a first groove is provided on the end of the insert facing the second hydraulic cylinder, and a second groove is provided on the end of the fixing block provided on the second hydraulic cylinder. The first groove and the second groove together form an interference groove.

[0022] The advantages of this invention compared to the prior art are:

[0023] 1. This invention, by setting up a moving mold core, a fixed mold core, a fixing component, and a forming pillar, enables the integrated molding of die-cast parts with inserts for new energy vehicles. Before die casting, the mold maker uses positioning equipment to precisely position the insert and securely clamps it with the fixing component, ensuring that the insert is suspended in the die-casting cavity. Subsequently, the moving mold core and the fixed mold core close to form a complete die-casting cavity. After the molten metal is injected, it completely encapsulates and fills the cavity with the insert. After cooling and solidification, the insert is firmly embedded inside the die-cast part, eliminating the need for subsequent assembly and greatly improving production efficiency and product quality.

[0024] 2. By incorporating auxiliary structures such as multiple molding rods, ejector rods, and ejector pins, the die-casting process is further optimized and demolding efficiency is improved. The multiple molding rods form part of the die-casting cavity during mold closing, ensuring the precise shape of the die-casting part. During mold separation, each molding rod retracts sequentially, avoiding obstruction to the die-casting part. The ejector rods and ejector pins work together after mold separation to smoothly eject and remove the die-casting part from the fixed and moving mold cores, achieving rapid demolding. Furthermore, the venting grooves effectively eliminate air from the die-casting cavity, ensuring the density and strength of the die-casting part. The design of two sets of die-casting cavities significantly improves production efficiency, enabling the die-casting mold to simultaneously die-cast two parts with inserts.

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figures 1-3 A die-casting mold for a die-casting part with inserts for new energy vehicles, comprising a moving mold core 2, a fixed mold core 1, a fixing component 3 for fixing the inserts 4, and a forming column 5;

[0041] The moving mold core 2 and the fixed mold core 1 are arranged horizontally, and the moving mold core 2 can move along the arrangement direction of the moving mold core 2 and the fixed mold core 1;

[0042] The fixing component 3 is located on one side of the moving mold core 2 and can move synchronously with the moving mold core 2;

[0043] The molding column 5 is installed through the moving mold core 2. The fixing component 3 fixes the insert 4. After the moving mold core 2 and the fixed mold core 1 are closed, the insert 4 does not contact the side wall of the moving mold core 2 or the side wall of the fixed mold core 1. The molding column 5 is located on one side of the insert 4. The end of the molding column 5 near the fixed mold core 1 extends from one side of the moving mold core 2 and forms a die-casting cavity with the closed moving mold core 2 and the fixed mold core 1. The insert 4 is located in the die-casting cavity.

[0044] When die-casting a die-cast part with insert 4, insert 4 needs to be placed into the die-casting mold cavity before die-casting. After die-casting, insert 4 is directly embedded in the die-cast part and cannot be removed from the die-cast part. During die-casting, the mold maker positions insert 4 on one side of the moving mold core 2 using a positioning device and clamps insert 4 using a fixing component 3. After being clamped by the fixing component 3, there is a first gap between insert 4 and the side wall of the moving mold core 2 facing the fixed mold core 1. Subsequently, the moving mold core 2 moves towards the fixed mold core 1 and finally closes with the fixed mold core 1. After closing, the moving mold core 2 and the fixed mold core 1 form the die-casting mold cavity, and insert 4 is located in the die-casting mold cavity. At this time, insert 4 and fixed mold core 1 are... There is a second gap between them. When the fixing component 3 is ignored, the insert 4 is suspended in the die casting mold cavity. Then, molten liquid metal is injected into the die casting mold cavity. The liquid metal casting that enters the die casting mold cavity fills the die casting mold cavity and wraps the insert 4. After subsequent cooling, the cooled and solidified die casting wraps the insert 4 inside it. Thus, after the die casting is completed, the insert 4 can be embedded in the die casting, thereby completing the one-piece molding of the die casting with the insert 4.

[0045] Reference Figure 6 The fixing component 3 includes a first hydraulic cylinder 31, a second hydraulic cylinder 32, and a fixing block 33;

[0046] The first hydraulic cylinder 31 is vertically mounted on one side of the moving mold core 2;

[0047] The second hydraulic cylinder 32 is disposed on the other side of the moving mold core 2 along the extension direction of the first hydraulic cylinder 31;

[0048] There are two fixing blocks 33, which are respectively fixed on the output end of the first hydraulic cylinder 31 and the output end of the second hydraulic cylinder 32.

[0049] The axis of the output shaft of the first hydraulic cylinder 31 is collinear with the axis of the output shaft of the second hydraulic cylinder 32. Before die casting, the mold maker places the insert 4 between the first hydraulic cylinder 31 and the second hydraulic cylinder 32. Then, the first hydraulic cylinder 31 and the second hydraulic cylinder 32 drive the fixing blocks 33 set on their corresponding ends to move closer to each other. At the same time, the two fixing blocks 33 fix and clamp the two ends of the insert 4. The insert 4 is a cylindrical structure. A positioning device is required during the installation of the insert 4. The positioning device is existing technology and will not be described in detail here. The positioning device positions the insert 4 to ensure that the axis of the insert 4 is collinear with the axis of the output shaft of the first hydraulic cylinder 31.

[0050] Reference Figure 7 Multiple first forming rods 34 are provided through the fixed block 33 connected to the first hydraulic cylinder 31 along the arrangement direction of the moving mold core 2 and the fixed mold core 1. The ends of the first forming rods 34 extend from the end face of the fixed block 33 and form part of the die casting mold cavity.

[0051] After the moving mold core 2 and the fixed mold core 1 are closed, the end of the protruding first forming rod 34 forms part of the die-casting mold cavity.

[0052] Reference Figures 2-4 A second forming rod 21 is also provided on the moving mold core 2. When the mold is closed, the end faces of the fixed mold core 1 and the moving mold core 2 that are in contact with each other are called reference end faces. The reference end faces are vertical. The plane formed by the second forming rod 21 and the insert 4 is parallel to the reference end face, and one end of the second forming rod 21 abuts against the forming post 5.

[0053] The second forming rod 21 can slide in the moving mold core 2 along its own extension direction. A third hydraulic cylinder 22 is provided at the end of the second forming rod 21 away from the fixed mold core 1 to drive the movement of the second forming rod 21. Before mold closing, the output end of the third hydraulic cylinder 22 is in an extended state, and the second forming rod 21 extends into the interior of the die casting mold cavity. The part of the second forming rod 21 extending into the die casting mold cavity constitutes part of the die casting mold cavity. After die casting is completed, after the moving mold core 2 separates from the fixed mold core 1, the third hydraulic cylinder 22 drives the second forming rod 21 to retract, which facilitates the demolding of the die casting attached to the moving mold core 2. If the second forming rod 21 is not retracted, the second forming rod 21 will obstruct the die casting, causing the second forming rod 21 to be unable to demold smoothly.

[0054] Reference Figure 5 After the insert is fixed by the fixing component 3, a first groove is provided on one end of the insert facing the second hydraulic cylinder 32, and a second groove is provided on the end of the fixing block 33 on the second hydraulic cylinder 32. The first groove and the second groove together form an interference groove 35. When the mold is closed, the second forming rod 21 passes through the interference groove 35 and abuts against the forming column 5.

[0055] When the second forming rod 21 extends into the die-casting mold cavity, the insert and the fixed block 33 set on the second hydraulic cylinder 32 will interfere with the second forming rod 21. Therefore, a first groove needs to be opened on the insert and a second groove needs to be opened on the fixed block 33. The first groove and the second groove together form an interference groove 35, so that the second forming rod 21 can pass smoothly through the connection between the fixed block 33 and the insert and abut against the forming column 5. When the moving mold core 2 and the fixed mold core 1 are separated, the second forming rod 21 is not removed first. After the moving mold core 2 and the fixed mold core 1 are separated, the second forming rod 21 is driven to be removed by the third hydraulic cylinder 22, so that when the moving mold core 2 and the fixed mold core 1 are separated, the die-casting part can be attached to the moving mold core 2 and move together with the moving mold core 2.

[0056] Reference Figure 13A third forming rod 23 is also provided on the moving mold core 2. The third forming rod 23 is provided through the moving mold core 2 and slides with the moving mold core 2. The extension direction of the third forming rod 23 is parallel to the horizontal plane and has an angle with the moving direction of the moving mold core 2. The fourth hydraulic cylinder 24 is provided at the end of the third forming rod 23 away from the fixed mold core 1 and is used to drive the third forming rod 23 to move.

[0057] Before the moving mold core 2 and the fixed mold core 1 are closed, the third forming rod 23 extends from the end face of the moving mold core 2 near the fixed mold core 1. After the moving mold core 2 and the fixed mold core 1 are closed, the part of the third forming rod 23 extending from the end face of the moving mold core 2 constitutes part of the die casting mold cavity. After the fixed mold core 1 and the moving mold core 2 are separated, the fourth hydraulic cylinder 24 drives the third forming rod 23 to retract into the moving mold core 2.

[0058] Reference Figure 10 An ejector rod 11 is provided through the fixed mold core 1 along the moving direction of the moving mold core 2. When the mold is closed, the end of the ejector rod 11 facing the moving mold core 2 is coplanar with the end face of the fixed mold core 1. A fifth hydraulic cylinder 12 is provided at the end of the ejector rod 11 away from the moving mold core 2 to drive the ejector rod 11 to move.

[0059] When die casting is completed and the moving mold core 2 separates from the fixed mold core 1, the fifth hydraulic cylinder 12 pushes the ejector rod 11, causing the ejector rod 11 to move synchronously with the moving mold core 2. The ejector rod 11, which is set on the fixed mold core 1, pushes the die casting off the fixed mold core 1, so that the die casting can be smoothly separated from the fixed mold core 1. This avoids the situation where, during mold separation, the first forming rod 34, the second forming rod 21, and the third forming rod 23 are not withdrawn, and the die casting is subjected to a pulling force in the direction of movement of the moving mold core 2, which would cause the die casting to be pulled and damaged. With the fifth hydraulic cylinder 12, the pulling effect on the die casting during the separation of the moving mold core 2 and the fixed mold core 1 can be avoided.

[0060] Reference Figures 1-13 The die casting mold also includes an injection port 13 for injecting molten metal. A moving mold core 2 and a fixed mold core 1 form a set of die casting cavities. The die casting mold has two sets of die casting cavities and is located on both sides of the injection port 13. The injection port 13 is connected to the two sets of die casting cavities respectively.

[0061] By setting up two sets of die-casting cavities, a pair of die-cast parts with inserts 4 can be produced simultaneously in each die-casting cycle, thus improving die-casting efficiency.

[0062] Reference Figure 12 The moving mold core 2 is provided with an exhaust groove 6 that communicates with the die-casting mold cavity. The exhaust groove 6 has a meandering structure.

[0063] After the molten liquid metal is injected through the injection port 13, the air in the die-casting mold cavity is discharged through the venting groove 6. After the moving mold core 2 and the fixed mold core 1 are closed, the actual size of the venting groove 6 is very small. Therefore, when the air in the die-casting mold cavity is discharged through the venting groove 6, the pressure in the die-casting mold cavity can be guaranteed.

[0064] Reference Figure 11 A ejector pin 26 is provided through the moving mold core 2 along the moving direction of the moving mold core 2, and a top plate 25 is fixedly provided at the end of the ejector pin 26 away from the fixed mold core 1.

[0065] After die casting is completed, the moving mold core 2 separates from the fixed mold core 1. Then, the third hydraulic cylinder 22 drives the second forming rod 21 to retract, and the fourth hydraulic cylinder 24 drives the third forming rod 23 to retract. At the same time, the first hydraulic cylinder 31 and the second hydraulic cylinder 32 respectively drive the corresponding fixing block 33 to retract. The first forming rod 34 set on the fixing block 33 is withdrawn from the die casting along with the fixing block 33, so that the first forming rod 34, the second forming rod 21 and the third forming rod 23 no longer hinder the separation of the die casting. Then, the top plate 25 is hydraulically driven and pushes the ejector pin 26 to extend from the end face of the moving mold core 2, thereby ejecting the die casting attached to the moving mold core 2 and separating it.

[0066] Working principle: First, the mold maker uses a positioning device to place the cylindrical insert 4 between the first hydraulic cylinder 31 and the second hydraulic cylinder 32, and then starts the first and second hydraulic cylinders, causing the fixing blocks 33 on the output ends of the first and second hydraulic cylinders to move closer together and clamp both ends of the insert 4. The positioning device ensures that the axis of the insert 4 is collinear with the axis of the output shaft of the first hydraulic cylinder 31. At this time, there is a first gap between the insert 4 and the side wall of the moving mold core 2 facing the fixed mold core 1. At the same time, the forming column 5, which is installed through the moving mold core 2, extends from the side wall of the moving mold core 2 near the fixed mold core 1. The forming column 5, the moving mold core 2, and the fixed mold core 1 together form the basic shape of the die-casting mold cavity. The insert 4 is located in the die-casting mold. A second gap exists between the cavity and the side wall of the fixed mold core 1. The end of the first forming rod 34 inside the fixed block 33 extends out to form part of the die-casting mold cavity. The second forming rod 21 on the moving mold core 2 extends into the die-casting mold cavity under the drive of the third hydraulic cylinder 22. The insert has a first groove at the end facing the second hydraulic cylinder 32, and the end of the fixed block 33 on the second hydraulic cylinder 32 has a second groove. The first groove and the second groove form an interference groove 35. The second forming rod 21 passes through the interference groove 35 and abuts against the forming column 5. The third forming rod 23 on the moving mold core 2 extends out from the side wall of the moving mold core 2 near the fixed mold core 1 under the drive of the fourth hydraulic cylinder 24, forming part of the mold cavity. The moving mold core 2 is also provided with a meandering venting groove 6 that communicates with the mold cavity. Then, the moving mold core 2 moves toward the fixed mold core 1 and completes the closure, forming a complete die-casting mold cavity. Then, molten liquid metal is injected into the die-casting mold cavity through the injection port 13. The liquid metal fills the mold cavity and wraps the insert 4, and then cools and solidifies. After cooling, the moving mold core 2 and the fixed mold core 1 begin to separate. The fifth hydraulic cylinder 12 drives the ejector rod 11 on the fixed mold core 1 to push, allowing the die-casting part to separate smoothly from the fixed mold core 1, preventing the die-casting part from being pulled and damaged. After separation, the third hydraulic cylinder 22 drives the second forming rod 21, the fourth hydraulic cylinder 24 drives the third forming rod 23, and the first hydraulic cylinder 31 and the second hydraulic cylinder 32 respectively drive the corresponding fixing blocks 33 to retract, so that the first forming rod 34, the second forming rod 21, and the third forming rod 23 no longer obstruct the die-casting part from detaching. Finally, the top plate 25 is hydraulically driven to push the ejector pin 26 out from the end face of the moving mold core 2, ejecting the die-casting part attached to the moving mold core 2 and detaching it, completing the entire die-casting process. In addition, the die-casting mold has two sets of die-casting cavities located on both sides of the injection port 13, which can simultaneously produce a pair of die-casting parts with inserts 4, improving die-casting efficiency.
