Description

Technical Field

[0001] The utility model belongs to the technical field of LEDs, and in particular relates to an LED bracket mould. Background Art

[0002] LED, also known as light-emitting diode, is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light. As a new generation of green lighting source, LED has many advantages such as high light efficiency, long life, safety, energy saving, and environmental protection. The normal use of LED is inseparable from the LED bracket. The LED bracket mold structure currently produced on the market is generally complex, and the precision of the molded products is not high.

[0003] The existing patent with announcement number CN215619484U discloses an LED bracket mold, including a base, columns are fixedly installed at both ends of the top of the base, a hydraulic rod is fixedly set on the top of the column, a support block is fixedly set on the telescopic axis of the hydraulic rod, and the same frame is fixedly connected between the two support blocks; a mounting frame is fixedly set on the frame, an adjusting cylinder is fixedly set in the mounting frame, a punching rod of the adjusting cylinder is fixedly set on the upper mold, and an upper module is fixedly set on the bottom of the upper mold; a lower mold is fixedly set on the base, an ejection cylinder is installed in the lower mold, a piston rod is arranged in the ejection cylinder, an ejection through hole is opened on the lower mold, an ejection plate is installed on the ejection cylinder, and a first ejection rod and a second ejection rod are arranged on the ejection plate; the first ejection rod and the second ejection rod extend to the top of the lower mold through the ejection through hole.

[0004] The above scheme performs die-casting on the bracket by adjusting the cylinder. After die-casting is completed, the ejector cylinder uses the reaction force to push the ejector plate upward, and the ejector plate pushes the first ejector rod and the second ejector rod to move upward through the ejection through hole on the lower mold, thereby pushing the bracket to be demolded. The ejector rod is in contact with part of the bracket, the contact area is small, and the stress at the contact point is large. If the bracket after die-casting is lifted by the first and second ejector rods alone, the lifting effect is not good and it is easy to cause damage to the bracket. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model. Embodiment 1

[0026] like Figure 1-Figure 6 As shown, the technical solution adopted by the utility model is as follows: an LED bracket mold includes a base 1, and a vertical plate 2 is fixedly arranged on one side of the top of the base 1.

[0027] The top of the vertical plate 2 is fixed with a motor 6, and a first groove 7 is provided on the vertical plate 2. The output shaft of the motor 6 movably passes through the top of the vertical plate 2 and extends into the first groove 7. The output shaft of the motor 6 is coaxially fixed with a first screw rod 5, and the bottom of the first screw rod 5 is rotatably connected to the bottom inner wall of the first groove 7.

[0028] The first screw rod 5 is threadedly connected to the support plate 3 . The support plate 3 can slide in the first groove 7 along the direction of the axis of the first screw rod 5 . An upper mold 22 is fixedly disposed at the bottom of the support plate 3 .

[0029] A first cylinder 4 is fixedly disposed on one side of the vertical plate 2 , and a telescopic shaft of the first cylinder 4 is fixedly connected to the top of the support plate 3 .

[0030] A second groove 8 is provided at the top of the base 1, and a top plate 9 is slidably arranged in the second groove 8 along the vertical direction, and the second groove 8 and the top plate 9 together form a lower mold. A second cylinder 10 is fixedly arranged at the bottom of the base 1, and a telescopic shaft of the second cylinder 10 passes through the base 1 and extends into the second groove 8, and the telescopic shaft of the second cylinder 10 is fixedly connected to the bottom of the top plate 9.

[0031] The first cylinder 4 and the second cylinder 10 are connected via a pipeline.

[0032] Place the material on the top plate 9.

[0033] The motor 6 is started, and the output shaft of the motor 6 drives the first screw rod 5 to rotate, and the first screw rod 5 drives the support plate 3 to slide downward along the direction of the axis of the first screw rod 5, thereby controlling the support plate 3 to slide downward, and further realizing the upper mold 22 to slide downward.

[0034] When the support plate 3 slides downward, the telescopic shaft of the first cylinder 4 will be extended, and the extension of the telescopic shaft of the first cylinder 4 will extract the gas in the second cylinder 10 through the pipeline.

[0035] In the initial position, the bottom of the top plate 9 does not contact the bottom inner wall of the second groove 8 .

[0036] After the gas in the second cylinder 10 is extracted by the first cylinder 4 , the telescopic shaft of the second cylinder 10 will shrink, and the shrinkage of the telescopic shaft of the second cylinder 10 will drive the top plate 9 to slide downward in the second groove 8 .

[0037] The top plate 9 will contact the bottom of the second groove 8 during the downward sliding process, and when the top plate 9 contacts the inner wall of the bottom of the second groove 8, the top plate 9 stops sliding downward. At this time, the upper mold 22 just touches the upper surface of the bracket.

[0038] The upper mold 22 will also move downward a short distance under the push of the motor 6, and this short distance can better stamp the bracket.

[0039] After stamping is completed.

[0040] The output shaft of the motor 6 rotates in the reverse direction, and the output shaft of the motor 6 drives the first screw rod 5 to rotate in the reverse direction, thereby controlling the upper mold 22 to slide upward.

[0041] The upper mold 22 slides upward to push the telescopic shaft of the first cylinder 4, thereby controlling the extension of the telescopic shaft of the second cylinder 10 through the pipeline, and then driving the top plate 9 to slide upward in the second groove 8. The upward sliding of the top plate 9 pushes the stamped material to move upward, thereby performing a demolding process on the stamped material.

[0042] How it works

[0043] Place the material on the top plate 9.

[0044] The motor 6 is started, and the output shaft of the motor 6 drives the first screw rod 5 to rotate, and the first screw rod 5 drives the support plate 3 to slide downward along the direction of the axis of the first screw rod 5, thereby controlling the support plate 3 to slide downward, and further realizing the upper mold 22 to slide downward.

[0045] When the support plate 3 slides downward, the telescopic shaft of the first cylinder 4 will extend. The extension of the telescopic shaft of the first cylinder 4 will extract the gas in the second cylinder 10 through the pipeline, thereby controlling the contraction of the telescopic shaft of the second cylinder 10.

[0046] In the initial position, the bottom of the top plate 9 does not contact the bottom inner wall of the second groove 8 .

[0047] After the gas in the second cylinder 10 is extracted by the first cylinder 4 , the telescopic shaft of the second cylinder 10 will shrink, and the shrinkage of the telescopic shaft of the second cylinder 10 will drive the top plate 9 to slide downward in the second groove 8 .

[0048] The top plate 9 will contact the bottom of the second groove 8 during the downward sliding process, and when the top plate 9 contacts the inner wall of the bottom of the second groove 8, the top plate 9 stops sliding downward. At this time, the upper mold 22 just touches the upper surface of the bracket.

[0049] The upper mold 22 will also move downward a short distance under the push of the motor 6, and this short distance can better stamp the bracket.

[0050] After stamping is completed.

[0051] The output shaft of the motor 6 rotates in the reverse direction, and the output shaft of the motor 6 drives the first screw rod 5 to rotate in the reverse direction, thereby controlling the upper mold 22 to slide upward.

[0052] The upper mold 22 slides upward to push the telescopic shaft of the first cylinder 4, thereby controlling the extension of the telescopic shaft of the second cylinder 10 through the pipeline, and then driving the top plate 9 to slide upward in the second groove 8. The upward sliding of the top plate 9 pushes the stamped material to move upward, thereby performing a demolding process on the stamped material. Embodiment 2

[0053] like Figure 3-Figure 6 As shown, compared with the first embodiment, the present embodiment is provided with a first lubricating mechanism for lubricating the upper mold 22 on the support plate 3 , and a second lubricating mechanism for lubricating the lower mold on the base 1 .

[0054] The first lubrication mechanism includes a first rack 11, which is fixedly arranged on the vertical plate 2. A fifth groove 23 is provided in the support plate 3, and a third screw rod 21 is rotatably arranged in the fifth groove 23. One end of the third screw rod 21 close to the first rack 11 passes through the support plate 3 and extends to the outside of the support plate 3. One end of the third screw rod 21 close to the first rack 11 is fixedly sleeved with a first gear 12, and the first gear 12 is meshed with the first rack 11. The other end of the third screw rod 21 is rotatably connected to the inner side wall of the fifth groove 23.

[0055] The third screw rod 21 is threadedly connected to an “L”-shaped moving plate 24 , and a second sponge plate 25 is fixedly arranged on the moving plate 24 . The second sponge plate 25 is in contact with the support plate 3 and the upper mold 22 .

[0056] The second sponge plate 25 contains lubricant.

[0057] A third groove 13 is formed on the top of the base 1 , and the third groove 13 is used for placing the moving plate 24 .

[0058] When the motor 6 drives the support plate 3 to move toward the base 1, the support plate 3 drives the first gear 12 to move, and the first gear 12 engages with the first rack 11 to make the first gear 12 rotate around the axis of the third screw rod 21, that is, under the action of the first gear 12, the third screw rod 21 rotates.

[0059] The rotation of the third screw rod 21 will drive the movable plate 24 to slide along the axis of the third screw rod 21 in the direction away from the vertical plate 2. The sliding of the movable plate 24 will drive the second sponge plate 25 to slide synchronously. While sliding, the second sponge plate 25 will evenly apply the lubricant stored in itself to the surface of the upper mold 22 to facilitate the demoulding of the bracket.

[0060] When the first gear 12 is disengaged from the first rack 11, the movable plate 24 is located just above the third groove 13. As the upper mold 22 continues to slide downward, when the upper mold 22 is completely fitted with the base 1, the movable plate 24 is located just in the third groove 13.

[0061] The second lubricating mechanism comprises a moving block 14 . The moving block 14 is fixedly arranged on one side of the supporting plate 3 . A second rack 15 is fixedly arranged on the moving block 14 .

[0062] A fourth groove 16 is provided at the top of the base 1. The fourth groove 16 has a larger opening at one end close to the moving block 14 for sliding of the second rack 15. A second screw rod 17 is rotatably arranged in the fourth groove 16. Both ends of the second screw rod 17 are rotatably connected to the base 1.

[0063] A second gear 18 is fixedly sleeved on one end of the second screw rod 17 close to the moving block 14 , and the second gear 18 is meshed with the second rack 15 .

[0064] The second screw rod 17 is threadedly connected to a push plate 19 , and a first sponge plate 20 is fixedly disposed on the push plate 19 . The first sponge plate 20 is in contact with the base 1 .

[0065] The first sponge plate 20 contains lubricant.

[0066] When the motor 6 drives the support plate 3 to move closer to the base 1 , the support plate 3 drives the moving block 14 and the second rack 15 to move synchronously.

[0067] Since the second rack 15 is meshed with the second gear 18, the second rack 15 will drive the second gear 18 to rotate around the axis of the second screw rod 17 during its movement. That is, the second gear 18 drives the second screw rod 17 to rotate.

[0068] The rotation of the second screw 17 will drive the push plate 19 and the first sponge plate 20 to slide along the axis of the second screw 17 toward the second gear 18, so that the lubricant in the first sponge plate 20 is evenly spread on the surface of the lower mold formed by the second groove 8 and the top plate 9, so as to facilitate the subsequent demolding of the model.

[0069] Before the upper mold 22 is completely fitted with the base 1 , the push plate 19 has already moved to the end of the second screw rod 17 close to the second gear 18 , which will not affect the fitting of the upper mold 22 with the base 1 .

[0070] How it works

[0071] When the motor 6 drives the support plate 3 to move toward the base 1, the support plate 3 drives the first gear 12 to move, and the first gear 12 engages with the first rack 11 to make the first gear 12 rotate around the axis of the third screw rod 21, that is, under the action of the first gear 12, the third screw rod 21 rotates.

[0072] The rotation of the third screw rod 21 will drive the movable plate 24 to slide along the axis of the third screw rod 21 in the direction away from the vertical plate 2. The sliding of the movable plate 24 will drive the second sponge plate 25 to slide synchronously. While sliding, the second sponge plate 25 will evenly apply the lubricant it contains to the surface of the upper mold 22 to facilitate the demoulding of the bracket.

[0073] When the first gear 12 is disengaged from the first rack 11, the movable plate 24 is located just above the third groove 13. As the upper mold 22 continues to slide downward, when the upper mold 22 is completely fitted with the base 1, the movable plate 24 is located just in the third groove 13.

[0074] Furthermore, when the motor 6 drives the support plate 3 to move closer to the base 1 , the support plate 3 drives the moving block 14 and the second rack 15 to move synchronously.

[0075] Since the second rack 15 is meshed with the second gear 18, the second rack 15 will drive the second gear 18 to rotate around the axis of the second screw rod 17 during its movement. That is, the second gear 18 drives the second screw rod 17 to rotate.

[0076] The rotation of the second screw 17 will drive the push plate 19 and the first sponge plate 20 to slide along the axis of the second screw 17 toward the second gear 18, so that the lubricant in the first sponge plate 20 is evenly spread on the surface of the lower mold formed by the second groove 8 and the top plate 9, so as to facilitate the subsequent demolding of the model.

[0077] Before the upper mold 22 is completely fitted with the base 1 , the push plate 19 has already moved to the end of the second screw rod 17 close to the second gear 18 , which will not affect the fitting of the upper mold 22 with the base 1 .
