[0037] Example 1

[0038] Reference Figure 1 to Figure 3 , which is the first embodiment of the present invention, and provides a die-casting mold for a lower connecting plate, which includes a die-casting unit 1, a support unit 2 arranged above the die-casting unit 1, and a driving unit 3 arranged on the support unit 2;

[0039] The die casting unit 1 includes a die casting table 11, a fixed mold core 12 disposed inside the die casting table, a movable mold core 13 disposed above the fixed mold core 12, a top mold block 14 disposed at the bottom of the fixed mold core 12, and an injection pipe 15 disposed on one side of the movable mold core 13;

[0040] The support unit 2 includes a support seat 21 disposed on one side of the die casting table 11, a support arm 22 disposed on one side of the support seat 21, a straight cylinder 23 disposed on the support arm 22, and a pressing assembly 24 disposed inside the straight cylinder 23;

[0041] The driving unit 3 includes a driving roller 31 disposed on the supporting arm 22 , a rotating wheel 32 disposed on one side of the driving roller 31 , a transmission shaft 33 disposed on one side of the driving roller 31 , and a top mold 34 disposed on one side of the transmission shaft 33 .

[0042] Furthermore, the movable mold core 13 includes positioning rods 131 disposed on both sides thereof and demoulding springs 132 disposed on the positioning rods 131;

[0043] The positioning rods 131 pass through both sides of the movable mold core 13 and the fixed mold core 12 .

[0044] Furthermore, the support arm 22 includes a through slot 221 penetrating through one side thereof; the transmission shaft 33 is hinged in the through slot 221 .

[0045] Furthermore, the pressing assembly 24 includes a connecting member 241 disposed at an end thereof, and a T-shaped block 242 disposed at one side of the connecting member 241;

[0046] The connecting member 241 includes a connecting frame 2411 disposed on one side of the T-shaped block 242 , and a cone wheel 2412 disposed on the inner side of the connecting frame 2411 .

[0047] Furthermore, the driving roller 31 includes an inclined surface 311 disposed at its end, and a large gear ring 312 disposed at the bottom of the inclined surface 311;

[0048] The cone wheel 2412 is slidably matched with the inclined surface 311 .

[0049] It should be noted that the die casting table 11 is a rectangular parallelepiped, with a placement groove in the middle part, a set of fixed mold cores 12 are threadedly connected in the placement groove, and a set of movable mold cores 13 are arranged above the fixed mold cores 12. The mold core shape of the fixed mold core 12 is the bottom model of the lower connecting plate A, and the mold core of the movable mold core 13 is the end face model of the lower connecting plate A, and the bottom model of the lower connecting plate A is a relatively flat end face, while the upper end face of the lower connecting plate A is a convex part face, and a set of top mold blocks 14 are slidably connected to the bottom of the fixed mold core 12. Ensure that the side of the lower connecting plate A placed on the fixed mold core 12 is a flat surface, which is easy to be lifted and demolded by the top mold block 14.

[0050] Preferably, a group of injection pipes 15 are provided through one side of the movable mold core 13, and aluminum liquid is injected through the injection pipes 15, and the aluminum liquid flows from the movable mold core 13 into the fixed mold core 12 to die-cast the lower connecting plate A model.

[0051] Preferably, the injection tube 15 is a pressurized injection tube to ensure that the aluminum liquid can be fully filled into every position of the movable mold core 13 and the fixed mold core 12, and the injection tube 15 can lock the aluminum liquid inside the movable mold core 13 and the fixed mold core 12 to avoid casting defects or quality problems.

[0052] Preferably, a support unit 2 is fixedly connected to the right side of the die-casting table 11, and the support unit 2 provides vertical pressure for the die-casting unit 1, so that the aluminum liquid in the movable mold core 13 and the fixed mold core 12 is subjected to pressure casting. Among them, the support seat 21 is fixedly welded to the right side of the die-casting table 11, and a group of support arms 22 are extended above the support seat 21. The support arms 22 are L-shaped to provide a movable space for the die-casting of the die-casting table 11 below. A group of driving rollers 31 are hinged on the end surface of the support arm 22, and a group of through grooves 221 are penetrated on the side of the support arm 22. A group of straight cylinders 23 are fixedly arranged on the end surface of the support arm 22, and a group of down-pressing components 24 are slidably arranged in the straight cylinders 23. The down-pressing components 24 apply pressure to the movable mold core 13 and the fixed mold core 12 below.

[0053] Preferably, two groups of positioning rods 131 are provided at the same position of the movable mold core 13 and the fixed mold core 12, and the positioning rods 131 are located at the corners of the mold core. A group of demoulding springs 132 is sleeved on each group of positioning rods 131, and one end of the demoulding spring 132 is fixedly connected to the movable mold core 13, and the other end is fixedly connected to one side of the straight cylinder 23.

[0054] Preferably, the pressing assembly 24 can slide in the straight cylinder 23 to apply pressure to the mold below. A group of T-shaped blocks 242 are slidably connected in the straight cylinder 23, and a group of connecting members 241 are fixedly connected to one side of the end face of the T-shaped block 242, and the connecting member 241 is composed of a connecting frame 2411 fixedly connected to one side of the T-shaped block 242, and a cone wheel 2412 hinged on the inner side of the connecting frame 2411. The cone wheel 2412 can slide on the driving roller 31 to cause the T-shaped block 242 to slide up and down in the straight cylinder 23. The driving roller 31 has a special structure, wherein the end face of the driving roller 31 is an inclined surface 311, and a group of rotating wheels 32 are fixedly connected to the upper axis of the driving roller 31, and the driving roller 31 below can be driven to rotate by rotating the rotating wheels 32. When the driving roller 31 rotates, its inclined surface 311 rotates, and its cone wheel 2412 limited on the connecting frame 2411 will slide along one side of the inclined surface 311. Since the height of the inclined surface 311 changes, the cone wheel 2412 moves up and down along the inclined surface 311 .

[0055] Preferably, the T-shaped block 242 is a counterweight block with a relatively high density, which may be a lead block. The mold is pressed by its own weight, and under the action of the inclined surface 311 and the T-shaped block 242, when the inclined surface 311 moves to make the T-shaped block 242 pressed down to the lowest position, it has a self-locking function, does not require the use of additional equipment, reduces energy consumption, and has a simple structure and is more stable.

[0056] Usage process: During die casting, the T-shaped block 242, under the action of its own gravity, will make the inclined surface 311 in the initial position, that is, the side where the inclined surface 311 cooperates with the T-shaped block 242 is at the lowest position. At this position, the movable mold core 13 and the fixed mold core 12 below will be pressed tightly. First, aluminum liquid is injected into the movable mold core 13 through the injection pipe 15. Under the action of pressure pumping, the aluminum liquid can be fully filled into each position of the movable mold core 13 and the fixed mold core 12, and the aluminum liquid in the mold is cooled and stabilized to form the required lower connecting plate A casting. This process does not require manual clamping and positioning of the movable mold core 13 and the fixed mold core 12, and effectively improves work efficiency.

[0057] When demoulding, rotating the rotating wheel 32 will drive the driving roller 31 to rotate, thereby rotating the inclined surface 311, and then the cone wheel 2412 starts to move upward on the inclined surface 311, so that the T-shaped block 242 starts to move upward in the straight cylinder 23, and no longer presses the movable mold core 13 and the fixed mold core 12 below. The demoulding spring 132 on the movable mold core 13 is changed from the originally stretched state to the contracted state, pulling up the movable mold core 13 and separating it from the fixed mold core 12, and completing the demoulding.

[0058] In summary, the device significantly improves the die-casting efficiency and quality of the lower connecting plate A through the die-casting unit 1, the support unit 2 and the drive unit 3, ensuring uniform filling and precise molding of the casting. The drive unit 3 controls the T-shaped block 242 through mechanical transmission to achieve the separation and merging of the mold core and the ejection of the casting, simplifying the manual operation; the coordinated action of the tooth plate 341 and the slide bar 1432 smoothly completes the demoulding, reduces the adhesion between the casting and the mold, and improves the yield rate and the life of the mold.

[0059] Example 2

[0060] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: this embodiment further provides a die-casting mold for a lower connecting plate, which includes a fixed mold core 12 including a core plate 121 arranged at the bottom of the movable mold core 13, and a groove 122 arranged at the bottom of the core plate 121.

[0061] It should be noted that the fixed mold core 12 is a special structure, and the fixed mold core 12 is used to die-cast the bottom model of the lower connecting plate A during the die-casting process. The mold contour of the core plate 121 is consistent with the bottom of the lower connecting plate A, and a space capable of accommodating the fixed mold core 12 is provided in the middle position of the die-casting table 11. There is a convex plate on the end face of the core plate 121, and the convex plate can be snapped into the space of the die-casting table 11 to provide a supporting force for the core plate 121. A groove 122 is provided at the bottom of the core plate 121, and the core plate 121 and the groove 122 form a through groove, and a group of top modules 14 are slidably connected in the groove 122, and the top modules 14 fit tightly in the groove 122, ensuring that during the die-casting process, the core plate 121 can fit with the movable mold core 13 to die-cast into the required lower connecting plate A product.

[0062] Furthermore, the top module 14 includes a top block 141 disposed at the bottom of the core plate 121, a sealing block 142 disposed at one side of the top block 141, and four sets of support members 143 disposed at the bottom of the sealing block 142;

[0063] The support member 143 includes four groups of support rods 1431 disposed at the bottom of the sealing block 142 , and a sliding rod 1432 disposed at one side of each group of support rods 1431 .

[0064] It should be noted that the top module 14 fits tightly in the groove 122. The top block 141 is consistent in shape with the core plate 121, and the bottom of the top block 141 is fixedly connected to the sealing block 142, which can fit in the groove 122. During die-casting, the top block 141 fits tightly in the core plate 121, and the through groove originally formed by the core plate 121 and the groove 122 is blocked by the top block 141 and the sealing block 142 to form a sealed space. The top block 141 is embedded in the core plate 121, leaving enough space for the die-casting lower connecting plate A. Four groups of support members 143 are fixedly connected to the bottom side of the sealing block 142, and the support members 143 can provide supporting force for the top module 14, as well as upward top die force.

[0065] Preferably, four groups of support members 143 are fixedly connected to the bottom side of the sealing block 142. Among them, four groups of support rods 1431 are fixedly connected to the bottom of the sealing block 142. A group of sliding rods 1432 are fixedly extended outward from the bottom of each group of support rods 1431, and the sliding rods 1432 are clamped on the sliding rails 344. Under the cooperation with the sliding rails 344, the top module 14 moves up and down at a specified position.

[0066] Preferably, the top block 141 and the sealing block 142 are an integral structure, and the cut surface is smooth to prevent the end surface of the top block 141 from contacting the aluminum liquid, resulting in rough surface pits. The material can be H13 steel, which is a hot working die steel with good high temperature resistance and thermal fatigue resistance, and the cut surface is smooth to avoid adhesion to the casting.

[0067] Furthermore, the die casting table 11 includes a movable groove 111 disposed inside thereof;

[0068] The transmission shaft 33 includes a first gear 331 disposed at one side of the large gear ring 312 , a transmission rod 332 disposed at the bottom of the first gear 331 , and a second gear 333 disposed at the bottom of the transmission rod 332 .

[0069] It should be noted that a movable groove 111 is provided inside the die casting table 11, and the movable groove 111 can provide a movable space for the top mold 34. On the right side of the die casting table 11, a slot is provided upward to provide a movable space for the transmission shaft 33 and the gear plate 341. The transmission shaft 33 is hinged and limited in the through groove 221 on the support arm 22. The transmission shaft 33 transmits the power of the drive roller 31 to the gear plate 341. A circle of large gear ring 312 is welded along the circumference of the bottom of the drive roller 31, and a side gear of the large gear ring 312 is meshed with the first gear 331. A group of transmission rods 332 are fixedly connected to the bottom of the first gear 331, and a group of second gears 333 are fixedly connected to the bottom of the transmission rod 332. When the large gear ring 312 rotates with the drive roller 31, it will drive the transmission shaft 33 to rotate.

[0070] Furthermore, the top mold 34 includes a tooth plate 341 disposed on one side of the second gear 333 , a U-shaped plate 342 disposed on one side of the tooth plate, two sets of slide plates 343 disposed on the U-shaped plate 342 , and a slide rail 344 disposed on the slide plate 343 .

[0071] It should be noted that the top module 34 can drive the top module 14 to move up and down within a specified range. The tooth plate 341 is meshed on one side of the second gear 333, a set of U-shaped plates 342 are fixedly connected to the bottom of the tooth plate 341, and a set of slide plates 343 are fixedly connected to the side walls of the U-shaped plate 342, and a slide rail 344 is provided on the slide plate 343. The U-shaped plate 342 is in a U shape, so that the U-shaped plate 342 will not interfere with the second gear 333 and the transmission rod 332 inside when it moves.

[0072] Furthermore, the slide rail 344 includes a corrugated section 3441 disposed at the front end thereof, and a Z-shaped section 3442 disposed at one side of the corrugated section 3441;

[0073] The tooth plate 341 includes a short tooth plate 3411 disposed on one side of the second gear 333 , a long tooth plate 3412 disposed on one side of the short tooth plate 3411 , and a slow-release member 3413 disposed on the short tooth plate 3411 .

[0074] It should be noted that the slide rail 344 provided on the slide plate 343 has a special structure. First, the shape of the slide rail 344 is set to a wavy section 3441 on the side close to the second gear 333, and then the Z-shaped section 3442 is set behind the wavy section 3441. When the second gear 333 rotates counterclockwise, the tooth plate 341 begins to move to the right end under the meshing action. The slide bar 1432 first begins to bump up and down under the action of the wavy section 3441, causing the top block 141 to slightly move at the bottom of the core plate 121, which will produce a vibration effect on the lower connecting plate A of the casting above the top block 141, prompting the core plate 121 to separate from the lower connecting plate A in the movable core 13, reducing adhesion and avoiding adhesion during demoulding. Then the slide bar 1432 will come to the Z-shaped section 3442, and the slide bar 1432 will start to move upward, so that the top block 141 will move upward, and will be ejected from the bottom of the core plate 121, and the die-cast lower connecting plate A will be ejected, completing the demoulding task. The tooth plate 341 will be completely withdrawn from the space of the die-casting table 11, so that the staff can wipe the end surface of the top block 141 and add a release agent.

[0075] Preferably, the tooth plate 341 is composed of a short tooth plate 3411, a long tooth plate 3412 and a release member 3413, and the short tooth plate 3411 is on the far right. The short tooth plate 3411 and the long tooth plate 3412 are connected together by the release member 3413. The release member 3413 is composed of two sets of limiting shafts fixedly connected to the short tooth plate 3411 and the long tooth plate 3412, and a spring rod in the limiting shaft.

[0076] The other structures are the same as those in the first embodiment.

[0077] Preferably, since the T-block 242 is at the lowest position due to its own gravity, the rotating wheel 32 is rotated counterclockwise, and the driving roller 31 also rotates counterclockwise, pushing the T-block 242 upward, so that the movable mold core 13 is separated from the fixed mold core 12, and the staff can add a release agent into the movable mold core 13 and the fixed mold core 12 or perform other pre-die-casting work. In this process, the counterclockwise rotation of the driving roller 31 can also lift up the T-shaped block 242, and the counterclockwise rotation of the driving roller 31 causes the first gear 331 and the second gear 333 to rotate clockwise. When the second gear 333 rotates clockwise, the second gear 333 will first contact the short tooth plate 3411, and the short tooth plate 3411 will be pushed to the left by the second gear 333, and the slow-release member 3413 will be squeezed, so that the second gear 333 and the short tooth plate 3411 will have sliding friction. When the second gear 333 rotates, the slow-release member 3413 will be pushed to the left, compressing the short tooth plate 3411 to move toward the long tooth plate 3412. The second gear 333 and the short tooth plate 3411 are misaligned, and the tooth plate 341 cannot be driven to move, so that the top module 14 cannot move and is limited. The top block 141 is always located at the bottom of the core plate 121, blocking the core plate 121 to form a complete mold.

[0078] After that, the driving roller 31 continues to rotate counterclockwise, causing the T-shaped block 242 to start sliding down, and the aluminum liquid is pumped into the injection pipe 15. After the aluminum liquid is fully filled into each position of the movable mold core 13 and the fixed mold core 12, after the casting is cooled, the driving roller 31 is urged to rotate clockwise. Under the clockwise rotation, the inclined surface 311 moves to lift the T-shaped block 242. While the T-shaped block 242 is lifted, the second gear 333 rotates counterclockwise at the same time under the meshing action. Under the action of the slow release member 3413, the tooth plate 341 starts to move to the right, driving the slide rail 344 to move to the right, so that the top block 141 moves upward, lifts the mold core plate 121, and allows the lower connecting plate A to be demolded.

[0079] Usage process: Preparation stage before die-casting: Before the die-casting operation, it is necessary to ensure that the mold is set correctly. The operator rotates the wheel 32 counterclockwise, which drives the drive roller 31 to rotate counterclockwise. As the drive roller 31 rotates counterclockwise, the T-block 242 is lifted up accordingly, and then naturally falls back after the operator stops rotating the wheel. During the upward movement of the T-block 242, the movable mold core 13 is separated from the fixed mold core 12, providing sufficient space for the staff to add release agent or other preparatory work before die-casting. After completing the preparation work, the operator continues to rotate the wheel 32 counterclockwise, and the T-block 242 falls back to the initial position. During this process, the second gear 333 will not drive the tooth plate 341 to move, ensuring that the top block 141 is always located at the bottom of the core plate 121, achieving effective blocking of the core plate 121, forming a complete mold structure, and preparing for the die-casting process.

[0080] Die casting stage: At the beginning of the die casting process, molten aluminum liquid is pumped into the injection pipe 15 to ensure that the aluminum liquid can be fully and evenly filled into every corner of the movable mold core 13 and the fixed mold core 12. After the aluminum liquid is filled, the casting needs to be cooled and solidified in the mold. After the casting is cooled and fully solidified, the operator rotates the drive roller 31 clockwise, which triggers the movement of the inclined surface 311, thereby lifting the T-shaped block 242. While rotating the drive roller 31 clockwise, gear transmission occurs between the second gear 333 and the tooth plate 341, ensuring the coordinated movement between the various parts of the mold. The slide bar 1432 first produces up and down bumps under the action of the wavy interval 3441, causing the top block 141 to produce a micro-motion at the bottom of the core plate 121, producing a vibration effect on the lower connecting plate A of the casting above the top block 141, promoting the separation of the core plate 121 from the lower connecting plate A in the movable mold core 13, reducing adhesion, and preventing adhesion problems during demolding. Then, the slide bar 1432 moves to the Z-shaped interval 3442 and starts to move upward, driving the top block 141 upward, ejecting the die-cast lower connecting plate A from the bottom of the core plate 121 to achieve demolding. After the demolding task is completed, the tooth plate 341 completely withdraws from the space of the die-casting table 11, providing convenience for the operator to clean and maintain the end surface of the top block 141, ensuring the reusability of the mold.

[0081] Then, the rotating wheel 32 is rotated counterclockwise to make the T-shaped block 242 fall back, and the second gear 333 can also perform gear transmission with the tooth plate 341 to return the tooth plate to the movable groove 111 inside the die-casting table 11, so as to facilitate the next die-casting work.

[0082] In summary, the device greatly improves the efficiency and quality of the die-casting process of the lower connecting plate A by setting the die-casting unit 1, the support unit 2 and the drive unit 3. Not only does it realize the automated die-casting process, but it also effectively avoids the errors and inconsistencies that may occur in traditional manual operations. The die-casting unit 1 is responsible for accurately injecting the molten aluminum liquid into the mold, ensuring the uniform filling and precise molding of the casting. The support unit 2 provides a stable support for the mold, ensuring the stability and durability of the mold during the die-casting process. The drive unit 3 controls the lifting and lowering of the T-block 242 through precise mechanical transmission, realizes the separation and merging of the mold core, and the action of ejecting the molded casting, thereby significantly reducing the complexity and labor intensity of manual operation. At the same time, through the coordinated action of the tooth plate 341 and the slide bar 1432, the effective ejection of the molded casting by the ejector block 141 is realized, ensuring the smooth demoulding process and the integrity of the casting. By applying a vibration effect to the lower connecting plate A of the casting before demolding, the possibility of adhesion is effectively reduced, casting defects or mold damage caused by adhesion is avoided, and the product yield and mold service life are further improved.
