Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die for ribbing and matching of an aluminum profile heat dissipation shell. Background Technique

[0002] After retrieval, there is a publicly disclosed patent with the publication number CN212093998U in the field of mold technology, namely "a die for ribbing and matching of a notebook computer shell molding", which includes an upper die base and a lower die base. A female die is fixedly connected to the top of the lower die base, and a male die is installed at the bottom of the upper die base. Installation curves are provided in the middle of both the female die and the male die, and heating cores are fixedly connected inside the installation curves. A sinking groove is provided in the middle of the female die, and a padding block is slidably connected in the middle of the sinking groove. A telescopic assembly is provided between the padding block and the sinking groove. An inwardly converging groove is provided in the middle of the male die, and a blanking block is slidably connected in the middle of the inwardly converging groove. A telescopic assembly is also provided between the blanking block and the inwardly converging groove. An installation sunk ring is provided at the bottom of the male die, and a ribbing insert is fixedly installed at the bottom of the installation sunk ring. The material stamping deformation of the utility model is smooth, convenient for material taking, avoiding the material from falling and colliding after moving up with the male die, improving the product yield, and the replacement of components is quick and simple, saving time and effort, and can flexibly meet the production needs.

[0003] However, through understanding this document and combining with the actual production process, it is found that the following problems exist in this application. First, for the sheet material used in die-casting, when cutting, it is generally reserved relatively long, but its width is generally a fixed width, and the value by which the width of the sheet material exceeds the width required for actual use is not too large. Therefore, when performing die-casting, more attention needs to be paid to the placement position of the width, otherwise waste is likely to occur. At the same time, for some aluminum profile heat dissipation shells (including shells such as notebook computer shells), when die-casting, in many cases, convex plates or concave logo imprints need to be made on their outer shells, which generally requires secondary processing, but the processing principle is actually the same. One more processing procedure will increase the production cost. Therefore, a die for ribbing and matching of an aluminum profile heat dissipation shell is needed to solve the above problems.

[0006] (II) Technical Solutions

[0007] To achieve the above object, the utility model is realized through the following technical solutions: A die for ribbing and matching of an aluminum profile heat dissipation shell includes:

[0008] A bottom plate and a top plate. A concave die is fixedly installed on the upper surface of the bottom plate, and a convex die is fixedly installed on the lower surface of the top plate.

[0012] Preferably, a limiting guide rail is fixedly connected to the upper surface of the bottom plate, and the top plate is movably sleeved on the outer surface of the limiting guide rail.

[0013] Preferably, a positioning shaft is movably inserted into the lower surface of the stripping top block.

[0016] The utility model discloses a die for press-fitting ribs of an aluminum profile heat dissipation shell, and the beneficial effects thereof are as follows:

[0017] 1. For the ribbing and fitting die of the aluminum profile heat dissipation housing, by pressing two groups of toggle blocks towards the middle, the third spring is compressed, and at the same time, the clamping rod moves out of the clamping strip. At this time, the sample plate is removed, and then according to the size of the sample plate, two sample plates with an inner concave logo and an outer convex logo are made respectively. If an aluminum profile heat dissipation housing with an intaglio logo is required, the sample plate with the outer convex logo is installed on the outer surface of the knockout block on the concave die.

Then, the sheet material is placed on the concave die. During die-casting, the top plate presses the sliding strip, so that the first spring is compressed, and the sliding strip enters the inside of the connecting sleeve. At this time, the positioning shaft moves into the knockout block, so that the second spring is compressed, which is convenient for limiting the width placement position of the sheet material during use and reducing waste.

[0024] An embodiment of the present utility model discloses a ribbing and fitting die for an aluminum profile heat dissipation housing, as Figures 1-4 shown, including;

[0025] A bottom plate 1 and a top plate 2. A female die 4 is fixedly installed on the upper surface of the bottom plate 1, and a male die 7 is fixedly installed on the lower surface of the top plate 2. Stripping blocks 5 are arranged on the outer surfaces of the female die 4 and the male die 7, and a sample plate 9 is movably clamped on the outer surface of the stripping block 5;

[0026] A limiting stop 6. A U-shaped plate 17 is fixedly connected to the lower surface of the limiting stop 6, and an adjusting screw 16 is threadedly connected inside the U-shaped plate 17.

[0027] Refer to the appendix Figure 1 As shown in the figure, the limiting stop 6 includes a connecting sleeve 601, a sliding bar 602 and a first spring 603. The connecting sleeve 601 is fixedly connected to the upper surfaces of both ends of the U-shaped plate 17. The sliding bar 602 is movably inserted into the top of the connecting sleeve 601. The first spring 603 is slidably clamped inside the connecting sleeve 601. When the top plate 2 moves downward, it will squeeze the sliding bar 602, causing the first spring 603 to be compressed, and the sliding bar 602 to enter the inside of the connecting sleeve 601. At this time, the positioning shaft 10 moves into the stripping block 5, causing the second spring 11 to be compressed.

[0028] Refer to the appendix Figure 1 and 3 As shown in the figure, a chute is opened on the upper surface of the bottom plate 1. The connecting sleeve 601 is slidably connected to the upper surface of the chute. A rotating lever 8 is rotatably connected to the outer surface of the bottom plate 1. The adjusting screw 16 is fixedly connected to the rotating lever 8. The U-shaped plate 17 is slidably connected inside the bottom plate 1. By rotating the rotating lever 8 to adjust the adjusting screw 16, the two U-shaped plates 17 move relative to or away from each other on the outer surface of the adjusting screw 16.

[0029] Refer to the appendix Figure 1 As shown in the figure, a limiting guide rail 3 is fixedly connected to the upper surface of the bottom plate 1. The top plate 2 is movably sleeved on the outer surface of the limiting guide rail 3 to limit the up and down movement of the top plate 2 during die casting.

[0030] Refer to the appendix Figure 3 As shown in the figure, a positioning shaft 10 is movably inserted into the lower surface of the stripping block 5. A second spring 11 is movably sleeved on the outer surface of the bottom end of the positioning shaft 10. A clamping bar 15 is fixedly connected to the lower surface of the sample plate 9. The clamping bar 15 is movably inserted into the stripping block 5. Accommodating grooves are arranged on the outer surfaces of the female die 4 and the male die 7. The depth of the accommodating groove is equal to the sum of the thickness of the stripping block 5 and the thickness of the sample plate 9. The other end of the positioning shaft 10 is fixedly connected to the inner bottom of the accommodating groove.

[0031] Refer to the appendix Figure 3, on both inner sides of the material-returning top block 5, there are sliding-connected clamping rods 13. At the opposite ends of the two groups of clamping rods 13, there is a third spring 14. Fixing holes are formed on the outer surface of the clamping strip 15. The other ends of the clamping rods 13 are movably inserted into the fixing holes. Moving grooves are formed on the outer surface of the material-returning top block 5. On the outer surfaces of the opposite ends of the two groups of clamping strips 15, there are respectively fixedly connected with dial blocks 12. The dial blocks 12 are slidably connected inside the moving grooves. By pushing the middle parts of the dial blocks 12, the two groups of clamping rods 13 are moved out of the clamping strip 15, and at the same time, the third spring 14 is compressed.

[0032] Working principle: When the device is in use, first, rotate the dial rod 8 to rotate and adjust the adjusting screw rod 16, so that the two U-shaped plates 17 move on the outer surface of the adjusting screw rod 16 towards the opposite or the back sides, making the distances of the two limiting stoppers 6 from the center position of the die 4 the same. Then, place the sheet metal on the upper surface of the die 4 and between the two limiting stoppers 6. Then, use a stamping device to press the top plate 2 downward, so that the top plate 2 drives the punch 7 to move downward, making the two material-returning top blocks 5 contact the sheet metal. At the same time, the top plate 2 squeezes the sliding strip 602, making the first spring 603 compressed, and the sliding strip 602 enters the connecting sleeve 601. At this time, the positioning shaft 10 moves into the material-returning top block 5, making the second spring 11 compressed. At the same time, the two material-returning top blocks 5 respectively enter the die 4 and the punch 7, making the surface of the sample plate 9 flush with the surface of the punch 7 or the die 4. At this time, the sheet metal is die-cast into shape under the action of the die 4 and the punch 7. Then, the stamping device drives the top plate 2 to move upward. At this time, the die 4 is separated from the punch 7. At the same time, under the action of the second spring 11, the material-returning top block 5 moves outward, preventing the die-cast aluminum profile heat dissipation housing from getting stuck on the punch 7 or the die 4, and completing the die-casting of the aluminum profile heat dissipation housing without a logo;

[0033] At the same time, when it is necessary to set a concave or convex logo on the aluminum profile heat dissipation housing, by pressing the two dial blocks 12 towards the middle, the third spring 14 is compressed, and at the same time, the clamping rods 13 are moved out of the clamping strip 15. At this time, the sample plate 9 is removed. Then, according to the size of the sample plate 9, two sample plates 9 with an inner concave-shaped logo and an outer convex-shaped logo are made respectively, and then they are respectively installed on the outer surfaces of the two material-returning top blocks 5. At this time, if an aluminum profile heat dissipation housing with a concave logo is needed, the sample plate 9 with an outer convex-shaped logo is installed on the outer surface of the material-returning top block 5 on the die 4. On the contrary, the sample plate 9 with an outer convex-shaped logo is installed on the outer surface of the material-returning top block 5 on the punch 7, so as to facilitate the engraving of the logo when the die-cast housing is formed.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification is only to illustrate the principle of the present utility model.
