Description

Technical Field

[0001] The invention relates to the technical field of die-casting dies, in particular to a die-casting die for die-casting parts for communication products which is easy to quickly cool down. Background Art

[0002] In the production process of communication products, die-casting parts are key components, and their quality and production efficiency directly affect the market competitiveness of the entire product. Traditional die-casting molds often face the problem of slow cooling speed during the molding process. During the die-casting process, the metal liquid needs to be quickly cooled and solidified after being injected into the mold to form a stable die-casting. Therefore, the cooling efficiency of the mold is directly related to the production cycle and product quality of the die-casting parts.

[0003] In the prior art, die-casting molds for die-casting parts for communication products are usually cooled by natural cooling or simple air cooling or water cooling. The natural cooling method relies on the heat conduction and air convection of the mold itself to dissipate heat, which is extremely inefficient and difficult to meet the needs of efficient production. Although the air cooling method accelerates the air flow and improves the heat dissipation speed through devices such as fans, it is limited by the thermal conductivity of air and its cooling effect is still limited. The water cooling method cools the mold through a circulating water system. Compared with the first two methods, the cooling effect of the water cooling method is more significant, but there are still some problems in practical applications.

[0004] On the one hand, traditional water cooling systems often have difficulty in achieving uniform cooling of the mold. Due to the complex structure of the mold, different parts have different heat dissipation requirements, and traditional water cooling systems can usually only provide a single cooling path and flow rate, which is difficult to flexibly adjust according to the actual heat dissipation requirements of the mold. This may cause some parts of the mold to be overcooled, while other parts are undercooled, affecting the quality and consistency of the die-casting.

[0005] On the other hand, the traditional water cooling system lacks an intelligent flow control mechanism. During the die-casting process, the temperature of the mold is constantly changing, so the demand for cooling liquid also changes accordingly. However, the traditional water cooling system can usually only provide a fixed cooling liquid flow rate and cannot be adjusted in real time according to the actual temperature of the mold. This not only causes a waste of cooling liquid, but may also affect the performance and appearance of the die-casting due to excessive or insufficient cooling. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a die-casting mold for die-casting parts for communication products that is easy to quickly cool down, thereby solving the technical problems mentioned in the background technology.

[0013] As a further preferred embodiment of the present technical solution, a secondary tube is provided on the side wall of the liquid dispensing tube, a cross bar is slidably connected to the secondary tube, a sealing member is fixedly connected to one end of the cross bar, a protrusion and a limit block are fixedly connected to the other end of the cross bar, and the position of the protrusion corresponds to the position of the arc block, a first damping spring sleeved on the cross bar is provided between the limit block and the secondary tube, and a control rod is fixedly connected to the top of the limit block.

[0014] As a further preferred embodiment of the present technical solution, a fixed frame is fixedly connected to the bottom of the conveying pipe, a second gear is rotatably connected to the fixed frame, and a gear rod is meshingly connected to the upper and lower ends of the second gear.

[0015] As a further preferred embodiment of the present technical solution, push rods for pushing the sealing plate to move are fixedly connected to both sides of the upper gear rod, and an extension rod is fixedly connected to the bottom end of the lower gear rod, and the positions of the extension rod and the control rod correspond to each other.

This design ensures that the spraying action of the spray head and the flow control of the cooling liquid can be coordinated; by accurately controlling the spraying amount of the cooling liquid and reducing the spraying amount as the temperature of the lower mold drops, the waste of excessive cooling liquid is effectively prevented and resources are saved.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Combination Figure 1-Figure 8 As shown, the present invention provides a technical solution: the present invention relates to a die-casting mold for die-casting parts for communication products, the mold is designed to achieve rapid cooling and cooling to improve production efficiency and product quality, the die-casting mold comprises a base 1, a lower mold 2 is arranged on the base 1, and is used to form die-casting parts for communication products, a fixing frame 3 is arranged on the top of the base 1, and a first cylinder 5 is arranged on the top of the fixing frame 3, and an upper mold 4 is connected to the output end of the first cylinder 5, and is used to apply pressure to the die-casting part during the die-casting process. In order to achieve rapid cooling and cooling, a cooling component 6 is also arranged on the base 1;

[0030] The cooling assembly 6 is composed of a plurality of fixed rods 61, which are arranged in a circular array on the base 1. Each fixed rod 61 is provided with an annular tube 62, and a plurality of liquid dispensing tubes 63 are connected to the annular tube 62. The other end of the liquid dispensing tube 63 is connected to a hose 64, and the other end of the hose 64 is connected to a delivery pipe 65. The other end of the delivery pipe 65 is connected to a spray head 66 for uniformly spraying the cooling liquid onto the outer wall of the lower mold 2. The delivery pipe 65 is rotatably mounted on the fixed rod 61, and a guide rod 67 is fixedly connected to the bottom end of the spray head 66. Sealing plates 628 for sealing the spray head 66 are rotatably connected on both sides of the outer wall of the delivery pipe 65, and a second damping spring 629 is arranged between the two sealing plates 628. The cooling liquid is transported to the liquid dispensing tube 63, the hose 64, and the delivery pipe 65 through the annular tube 62. The cooling liquid is then sprayed into the delivery pipe 65, and then sprayed onto the outer wall of the lower mold 2 on the base 1 through the spray head 66, so that the die casting in the lower mold 2 can be quickly cooled and cooled. By controlling the up and down movement of the guide rod 67, the spray head 66 and the delivery pipe 65 can be driven to move up and down, thereby increasing the spray range of the cooling liquid, so that the cooling liquid can evenly cover the outer surface of the lower mold 2. As the temperature of the lower mold 2 drops, the two sealing plates 628 are controlled to move inward and compress the second damping spring 629, so that the two sealing plates 628 seal the spray holes of the spray head 66, that is, the number of spray holes that can spray cooling liquid is reduced, effectively preventing excessive cooling liquid from accidentally flowing out of the spray holes of the spray head 66, that is, as the temperature of the lower mold 2 drops, the spraying amount of the spray head 66 is reduced, thereby saving cooling liquid.

[0031] In order to further optimize the cooling effect and the convenience of operation, an annular frame 68 is rotatably connected to the base 1, a reciprocating groove 69 is provided on the top of the annular frame 68, the bottom end of the guide rod 67 is slidably installed in the reciprocating groove 69, the outer wall of the annular frame 68 is fixedly connected to the ring gear 610, a motor 611 is fixedly installed on the fixed rod 61, and the output end of the motor 611 is fixedly connected to the first gear 612 meshing with the ring gear 610, a sliding groove is provided on the outer wall of the annular frame 68, a vertical rod 613 is fixedly connected in the sliding groove, and an arc-shaped Block 614, a second cylinder 615 fixedly mounted on the annular frame 68 is provided at the bottom of the arc block 614, and the first gear 612 is driven to rotate synchronously by turning on the motor 611, and the first gear 612 drives the meshing gear ring 610 and the annular frame 68 to rotate synchronously, so that the reciprocating groove 69 at the top of the annular frame 68 drives the guide rod 67 to move up and down reciprocatingly, so that the guide rod 67 drives the conveying pipe 65 and the spray head 66 located on the fixed rod 61 to reciprocate up and down, thereby expanding the spray range of the spray head 66;

[0032] In order to achieve accurate control of the amount of cooling liquid sprayed, a secondary pipe 616 is provided on the side wall of the liquid dispensing pipe 63, and a cross bar 617 is slidably connected to the secondary pipe 616. A sealing member 618 is fixedly connected to one end of the cross bar 617, and a convex head 619 and a limiting block 620 are fixedly connected to the other end. The position of the convex head 619 corresponds to the position of the arc block 614. A first damping spring 621 sleeved on the cross bar 617 is provided between the limiting block 620 and the secondary pipe 616. A control rod 622 is fixedly connected to the top of the limiting block 620. The sealing member 618 uses a rubber sealing plug to seal the secondary pipe 616. The arc block 614 is pushed upward by opening the second cylinder 615, so that the position of the arc block 614 corresponds to the position of the convex head 619. At this time, when the annular frame 68 rotates, the arc block 614 is driven to rotate synchronously, so that The arc block 614 pushes the convex head 619, the cross bar 617, and the sealing member 618 to move toward the side of the liquid dispensing tube 63, and compresses the first damping spring 621, so that the movement of the sealing member 618 will block a part of the liquid dispensing tube 63, so that the cooling liquid flowing out of the liquid dispensing tube 63 at the same time is reduced. When the second cylinder 615 controls the arc block 614 to move downward, the elastic force of the first damping spring 621 pushes the limit block 620, the convex head 619, the cross bar 617, the sealing member 618, and the control rod 622 to reset, so that the reset of the sealing member 618 will no longer block the liquid dispensing tube 63, so that the cooling liquid flow rate in the liquid dispensing tube 63 becomes larger. In this way, the spraying amount of the cooling liquid can be intermittently controlled when spraying the cooling liquid, which can not only cool the lower mold 2, but also reduce the waste of the cooling liquid.

[0033] In order to ensure that the spraying action of the spray head 66 and the flow control of the cooling liquid can be coordinated, a fixed frame 623 is fixedly connected to the bottom of the delivery pipe 65, and a second gear 624 is rotatably connected to the fixed frame 623. The second gear 624 is meshed with a gear rod 625 at the upper and lower ends. Push rods 626 for pushing the sealing plate 628 to move are fixedly connected to both sides of the upper gear rod 625. An extension rod 627 is fixedly connected to the bottom end of the lower gear rod 625, and the positions of the extension rod 627 and the control rod 622 correspond to each other. When the control rod 622 moves to one side of the liquid dispensing tube 63, the control rod 622 can push the extension rod 627 to move synchronously. The extension rod 627 drives the second gear 624 to rotate through the lower gear rod 625, so that the second gear 624 drives the upper gear rod 625 to move, thereby making the upper gear rod 625 drive the push rod 626 to move synchronously, so that the push rod 626 pushes the sealing plate 628 to move inward and compresses the second damping spring 629.

[0034] In the embodiment of the present invention, during the cooling process, the liquid is transported by the annular tube 62 and guided to the liquid distribution tube 63, the hose 64 and the delivery tube 65. Subsequently, the cooling liquid is sprayed to the outer wall of the lower mold 2 on the base 1 through the spray head 66 to achieve rapid cooling and cooling of the die casting in the lower mold 2. This process ensures that the cooling liquid can evenly cover the outer surface of the lower mold 2 by expanding the spray range of the spray head 66 and the spray range of the cooling liquid, thereby achieving an effective cooling effect.

[0035] In addition, by starting the motor 611, the first gear 612 can be driven to rotate synchronously, and the rotation of the first gear 612 will drive the meshing gear ring 610 and the annular frame 68 to rotate synchronously, and the reciprocating groove 69 on the top of the annular frame 68 will drive the guide rod 67 to move up and down reciprocatingly, so that the guide rod 67 drives the delivery pipe 65 and the spray head 66 to rotate up and down on the fixed rod 61. This design not only increases the spraying range of the spray head 66, but also through this reciprocating motion, further ensures that the cooling liquid can evenly cover the outer surface of the lower mold 2, thereby improving the cooling efficiency;

[0036] In order to further optimize the cooling process, by starting the second cylinder 615, the arc block 614 can be pushed upward to make its position correspond to the position of the convex head 619. When the annular frame 68 rotates, it will drive the arc block 614 to rotate synchronously, thereby pushing the convex head 619, the cross bar 617 and the seal 618 to move to the side of the liquid distribution tube 63 and compressing the first damping spring 621. This action causes the seal 618 to move and block a part of the liquid distribution tube 63, thereby reducing the amount of cooling liquid flowing out of the liquid distribution tube 63 at the same time. When the second cylinder 615 controls the arc block 614 to move downward, under the elastic force of the first damping spring 621, the limit block 620, the convex head 619, the cross bar 617, the seal 618 and the control rod 622 will be reset, and the reset of the seal 618 will no longer block the liquid dispensing tube 63, so that the flow rate of the cooling liquid in the liquid dispensing tube 63 becomes larger. In this way, the spraying amount of the cooling liquid can be intermittently controlled when spraying the cooling liquid, which can effectively cool the lower mold 2 and reduce the waste of the cooling liquid.

[0037] As the temperature of the lower mold 2 gradually decreases, the control rod 622 will move toward the side of the liquid dispensing tube 63. The movement of the control rod 622 can push the extension rod 627 to move synchronously, and the extension rod 627 drives the second gear 624 to rotate through the lower gear rod 625. The rotation of the second gear 624 will drive the upper gear rod 625 to move, and then the upper gear rod 625 drives the push rod 626 to move synchronously. The movement of the push rod 626 pushes the sealing plate 628 to move inward and compresses the second damping spring 629, so that the two sealing plates 628 seal the spray holes of the spray head 66. In this way, the number of spray holes that can spray cooling liquid is reduced, which effectively prevents excessive cooling liquid from accidentally flowing out of the spray holes of the spray head 66. As the temperature of the lower mold 2 drops, the spraying amount of the spray head 66 is reduced accordingly, thereby saving the use of cooling liquid.

[0038] Working principle of a die-casting mold for a communication product that is easy to quickly cool down:

[0039] Step 1: The cooling liquid is transported to the liquid dispensing pipe 63, the hose 64, and the delivery pipe 65 through the annular pipe 62, and then sprayed to the outer wall of the lower mold 2 on the base 1 through the spray head 66, so that the die-casting in the lower mold 2 can be quickly cooled and cooled; then the motor 611 is turned on to drive the first gear 612 to rotate synchronously, and the first gear 612 drives the meshing gear ring 610 and the annular frame 68 to rotate synchronously, so that the reciprocating groove 69 on the top of the annular frame 68 drives the guide rod 67 to move up and down reciprocatingly, so that the guide rod 67 drives the delivery pipe 65 and the spray head 66 located on the fixed rod 61 to rotate up and down reciprocatingly, so that the spray range of the spray head 66 can be expanded, thereby increasing the spray range of the cooling liquid, so that the cooling liquid can evenly cover the outer surface of the lower mold 2;

[0040] Step 2: Open the second cylinder 615 to push the arc block 614 upward, so that the position of the arc block 614 corresponds to the position of the convex head 619. At this time, when the annular frame 68 rotates, the arc block 614 is driven to rotate synchronously, so that the arc block 614 pushes the convex head 619, the cross bar 617, and the sealing member 618 to move toward the side of the liquid dispensing tube 63, and compresses the first damping spring 621, so that the sealing member 618 moves to block a part of the liquid dispensing tube 63, so that the cooling liquid flowing out of the liquid dispensing tube 63 at the same time is reduced. When the second cylinder 615 controls the arc block 614 to move downward, the limit block 620, the convex head 619, the cross bar 617, the seal 618, and the control rod 622 are pushed to reset under the elastic force of the first damping spring 621, so that the reset of the seal 618 will no longer block the liquid dispensing tube 63, so that the flow rate of the cooling liquid in the liquid dispensing tube 63 becomes larger, so that the spraying amount of the cooling liquid can be intermittently controlled when spraying the cooling liquid, which can not only cool the lower mold 2, but also reduce the waste of the cooling liquid;

[0041] Step 3. As the temperature of the lower mold 2 drops, when the control rod 622 moves toward the side of the liquid dispensing tube 63, the control rod 622 can push the extension rod 627 to move synchronously. The extension rod 627 drives the second gear 624 to rotate through the lower gear rod 625, so that the second gear 624 drives the upper gear rod 625 to move, so that the upper gear rod 625 drives the push rod 626 to move synchronously, so that the push rod 626 pushes the sealing plate 628 to move inward and compresses the second damping spring 629, so that the two sealing plates 628 seal the spray holes of the spray head 66, that is, the number of spray holes that can spray cooling liquid is reduced, effectively preventing excessive cooling liquid from accidentally flowing out of the spray holes of the spray head 66, that is, as the temperature of the lower mold 2 drops, the spraying amount of the spray head 66 is reduced, thereby saving cooling liquid.
