Description

Technical Field

[0001] This utility model relates to the field of die-casting molds, and in particular to a die-casting mold for a motorcycle cover to prevent deformation. Background Technology

[0002] Motorcycles, with their diverse forms, meet different needs. The core components—engine, frame, suspension, and braking system—together form the foundation of their high performance and ensure driving safety.

[0003] When producing the right axle box cover for motorcycles, the moving mold is first connected to the fixed mold, and then injection is performed through the injection port. After cooling and molding, the mold is separated and ejected. However, during this process, the clamping force of the mold when the casting is ejected can easily cause the product to deform during production. This requires additional steps to make shaping tools, resulting in low production efficiency.

[0004] Therefore, it is necessary to provide a new die-casting mold for motorcycle lids that prevents deformation in order to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a die-casting mold for motorcycle cover to prevent deformation.

[0006] The motorcycle anti-deformation box cover die-casting mold provided by this utility model includes a moving mold and a fixed mold. The fixed mold has a cavity. A telescopic member is provided on one side of the fixed mold. A side core is fixed at the telescopic end of the telescopic member. The telescopic member can drive the side core to move into the cavity. A tapered concave structure is provided inside the cavity. At least one filling groove is provided on the side wall of the tapered concave structure. The filling groove is a gradually transitioning structure from shallow on both sides to deep in the middle. A core is fixed on the moving mold. The core is correspondingly arranged with the cavity.

[0007] Preferably, the telescopic component includes a hydraulic cylinder and a slider. The hydraulic cylinder is fixed on the fixed mold, and the telescopic end of the hydraulic cylinder is fixedly connected to the slider. The slider is slidably disposed in the channel opened in the fixed mold, and one end of the slider is fixedly connected to the side core.

[0008] Preferably, the fixed mold has an injection hole and a drainage hole on one side in the lateral direction. The injection hole and the drainage hole are respectively connected to a first pipe and a second pipe inside the fixed mold. The ends of the first pipe and the second pipe away from the injection hole and the drainage hole extend to the outside of the fixed mold, and the first pipe and the second pipe are fixedly connected by a bend.

[0009] Preferably, multiple heat dissipation fins are fixed on the bent tube.

[0010] Preferably, a water injection hole and a drainage hole are provided on one longitudinal side of the fixed mold. The water injection hole and the drainage hole are respectively connected to a third transverse pipe and a fourth transverse pipe in the fixed mold. The third pipe and the fourth pipe are connected through a fifth longitudinal pipe. The third pipe, the fourth pipe and the fifth pipe are all partially located below the tapered concave structure.

[0011] Preferably, a fixed mating block is fixedly connected to the fixed mold, and a movable mating block is fixedly connected to the movable mold at a position corresponding to the fixed mating block.

[0012] Preferably, the fixed mold is also provided with an injection port, which is connected to the cavity through an injection pipe inside the fixed mold.

[0013] Compared with related technologies, the motorcycle anti-deformation box cover die-casting mold provided by this utility model has the following beneficial effects: 1. By setting a forming groove with a gradually transitioning structure from shallow on both sides to deep in the middle, after the aluminum alloy is solidified, an additional protrusion structure corresponding to the filling groove will appear on the surface of the casting. When the casting is ejected, the protrusion structure formed inside the cavity will hinder the ejection of local parts, thus forming a larger ejection resistance. This can counteract the larger mold clamping force in the opposite direction in local parts of the product. Finally, after the die casting is ejected, the dimensions meet the tolerance requirements of the drawing and reduce deformation problems.

[0014] 2. Coolant is introduced into the injection hole and the water injection hole. The coolant in the injection hole enters the first pipe, then flows into the bend pipe and then into the second pipe, and finally exits from the drain hole. The coolant injected into the water injection hole enters the third, fifth and fourth pipes, and finally exits from the drain hole. The cooling effect of the casting in the cavity is achieved through the first, second, third, fourth and fifth pipes. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figures 1-8 ,in, Figure 1 A schematic diagram of the structure of the motorcycle anti-deformation box cover die-casting mold provided by this utility model; Figure 2 for Figure 1 The diagram shows a partial decomposition of the fixed mold structure.

Figure 3 ; Figure 8 This is a schematic diagram of the structure of the product manufactured using this mold.

[0019] In the specific implementation process, such as Figures 1-8As shown, the system includes a moving mold 1 and a fixed mold 23. The fixed mold 23 has a cavity 2. A telescopic component is provided on one side of the fixed mold 23, and a side core 3 is fixed to the telescopic end of the component. The telescopic component can drive the side core 3 to move into the cavity 2. A tapered concave structure 4 is provided inside the cavity 2. At least one filling groove 5 is provided on the side wall of the tapered concave structure 4. The filling groove 5 has a gradually transitioning structure from shallow at both sides to deep in the middle. A core 6 is fixed on the moving mold 1, and the core 6 connects to the cavity. 2 Corresponding settings: Through the setting of the forming groove with a gradually transitioning structure from shallow on both sides to deep in the middle, after the aluminum alloy is solidified, an additional protrusion structure corresponding to the filling groove 5 will appear on the surface of the casting. When the casting is ejected, the protrusion structure formed inside the cavity 2 will hinder the ejection of local positions, thus forming a larger opposite ejection resistance. This can counteract the larger opposite mold clamping force in the local area of ​​the product 24. Finally, after the die casting is ejected, the dimensions meet the tolerance requirements of the drawing and reduce deformation problems. The telescopic component includes a hydraulic cylinder 7 and a slider 8. The hydraulic cylinder 7 is fixed on the fixed mold 23. The telescopic end of the hydraulic cylinder 7 is fixedly connected to the slider 8. The slider 8 is slidably disposed in the channel opened in the fixed mold 23. One end of the slider 8 is fixedly connected to the side core 3. The hydraulic cylinder 7 can drive the slider 8 and the side core 3 on it to move. During die casting, the hydraulic cylinder 7 is in the extended state, pushing the slider 8 and the side core 3 into the cavity 2, forming a complete cavity 2 together with other parts of the mold. After die casting is completed, the hydraulic cylinder 7 retracts, pulling the side core 3 out of the formed casting. After the core pulling action is completed, the mold is opened, and then the ejector plate moves to eject the product 24. The fixed mold 23 has a liquid injection hole 9 and a liquid drain hole 10 on one side of its transverse direction. The liquid injection hole 9 and the liquid drain hole 10 are respectively connected to a first pipe 11 and a second pipe 12 inside the fixed mold 23. The ends of the first pipe 11 and the second pipe 12 away from the liquid injection hole 9 and the liquid drain hole 10 extend to the outside of the fixed mold 23, and the first pipe 11 and the second pipe 12 are fixedly connected by a bent pipe 13. Multiple heat dissipation fins 14 are fixed on the bent pipe 13 to facilitate heat dissipation. The fixed mold 23 has a water injection hole 15 and a water drain hole 16 on one side of its longitudinal direction. The water injection hole 15 and the water drain hole 16 are respectively connected to a third transverse pipe 17 and a fourth transverse pipe 18 inside the fixed mold 23. The third pipe 17... The fourth pipe 18 is connected to the fifth pipe 19 in the longitudinal direction. The third pipe 17, the fourth pipe 18 and the fifth pipe 19 are all partially located below the tapered concave structure 4. The coolant is injected into the cavity 2 through the injection port 22 and introduced into the injection hole 9 and the water injection hole 15. The coolant in the injection hole 9 enters the first pipe 11, enters the bend pipe 13 after the first pipe 11 and then flows into the second pipe 12. Finally, it is discharged from the drain hole 10. The coolant injected into the water injection hole 15 enters the third pipe 17, the fifth pipe 19 and the fourth pipe 18 and is finally discharged from the drain hole 16. The cooling effect of the casting in the cavity 2 is achieved through the first pipe 11, the second pipe 12, the third pipe 17, the fourth pipe 18 and the fifth pipe 19. A fixed docking block 20 is fixedly connected to the fixed mold 23, and a movable docking block 21 is fixedly connected to the movable mold 1 at the position corresponding to the fixed docking block 20. The fixed docking block 20 and the movable docking block 21 facilitate the stable docking of the movable mold 1 and the fixed mold 23. The fixed mold 23 is also provided with an injection port 22. The injection port 22 is connected to the cavity 2 through the injection pipeline in the fixed mold 23. The injection port 22 and the injection pipeline are used to inject into the cavity 2. It should be noted that in actual use in this field, an ejector plate is also provided on one side of the moving mold 1. Multiple ejector pins are installed on the ejector plate. One end of the multiple ejector pins moves through the moving mold 1 and the core 6. During injection, the front end of the ejector pin is flush with the surface of the core 6, which will not affect the molding of the product 24. The ejector pins facilitate the ejection of the casting.

[0020] The working principle of this utility model is as follows: During use, the moving mold 1 moves onto the fixed mold 23 to perform a mold closing operation. Coolant is injected into the cavity 2 through the injection port 22, flowing into the injection hole 9 and the inner side of the water injection hole 15. The coolant in the injection hole 9 enters the first pipe 11, then flows through the bend pipe 13 and then into the second pipe 12, finally exiting from the drain hole 10. The coolant injected into the water injection hole 15 enters the third pipe 17, the fifth pipe 19, and the fourth pipe 18, finally exiting from the drain hole 16. The first pipe 11, the second pipe 12, the third pipe 17, the fourth pipe 18, and the fifth pipe 19 achieve the cooling effect on the casting in the cavity 2. After the aluminum alloy solidifies and forms, a raised structure corresponding to the filling groove 5 will appear on the surface of the casting. When the casting is ejected, the raised structure formed inside the cavity 2 will hinder the ejection of local parts, thus forming a large opposite ejection resistance. This can counteract the large opposite mold clamping force in the local part of the product 24. Finally, after the die casting is ejected, the dimensions meet the tolerance requirements of the drawing and reduce deformation problems.

[0021] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
