Description

Technical Field

[0001] This utility model relates to the field of sheet metal stamping die technology, specifically to an easy-to-demold sheet metal stamping die. Background Technology

[0002] An easy-release sheet metal stamping die is a device used to quickly release stamped sheet metal from inside the die.

[0003] Based on the above, the inventors have discovered that: Currently, there are many sheet metal stamping dies on the market, but in general sheet metal stamping dies, workers put the sheet metal raw materials into the die and use a stamping machine to stamp the material into shape. This requires workers to use external force to break the die and remove the sheet metal, which seriously reduces the practicality of the die and easily causes wear on the edges of the sheet metal. Therefore, in view of this, the inventors have researched and improved the existing structure to provide an easy-to-demold sheet metal stamping die, in order to achieve a more practical value. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses an easy-to-demold sheet metal stamping die, including a base, a bracket fixed to the top of the base, a die body fixed to the top of the base, a stamping machine body fixed to the outer wall of the bracket, a pushing mechanism provided on the outer wall of the base, and a lifting mechanism provided on the outer wall of the base.

[0006] The propulsion mechanism includes:

[0007] A drive motor is provided, with its top end fixed to the outer wall of the base. The output end of the drive motor is coaxially connected to a drive gear, and the outer wall of the drive gear drives a driven gear. A lead screw is fixed to the top of the driven gear, and a slide plate is driven to the outer wall of the lead screw. Two push plates are provided at the top of the slide plate, and the outer walls of the two push plates are fitted with the inner wall of the mold body.

[0008] As a preferred embodiment of this utility model, the outer wall of the base is fixed with two support plates, and the outer wall of the two support plates is provided with a bottom plate, which is disposed at the bottom end of the driving gear and the driven gear.

[0009] As a preferred embodiment of this utility model, two blocks are fixed at the top of the skateboard, and the outer walls of the two blocks are matched with the inner wall of the push plate.

[0010] As a preferred embodiment of this utility model, the inner walls of both blocks are provided with horizontal plates, and the outer walls of both horizontal plates are fitted onto the inner wall of the push plate.

[0011] As a preferred embodiment of this utility model, the inner walls of both horizontal plates are equipped with sliding limit posts, and the bottom ends of both limit posts are matched with the inner walls of the sliding plate.

[0012] As a preferred embodiment of this utility model, the lifting mechanism includes:

[0013] A connecting plate is fixed to the outer wall of the base on both sides. A hydraulic pump is fixed to the top of the connecting plate, and a top block is fixed to the output end of the hydraulic pump. The outer wall of the top block is fitted into the middle of the bottom end of the inner wall of the mold body.

[0014] As a preferred embodiment of this utility model, two protrusions are fixed at the bottom end of the base plate, and the outer walls of the two protrusions are matched with the inner walls of the support plate.

[0015] The beneficial effects of this utility model are:

[0016] 1. This solution controls the drive motor to rotate the active gear, which in turn drives the driven gear to rotate. This drives the lead screw to rotate, causing the slide plate to move up and down during the rotation of the lead screw. This causes the push plate to fit against the inner wall of the mold, pushing the bottom sides of the stamped sheet metal upwards. A hydraulic pump drives the top block to move up and down, pushing the top block against the middle of the bottom of the stamped sheet metal. This effectively improves the demolding of the stamped sheet metal.

[0017] 2. In this scheme, the outer walls of the two push plates are respectively fitted onto the inner wall of the mold body, so that both push plates are installed at the top of the slide plate. Then, the inner wall of the push plate matches and is installed with the outer wall of the block fixed at the top of the slide plate. The outer wall of the horizontal plate is fitted onto one side of the push plate, so that the outer wall of the horizontal plate engages and is installed with the inner wall of the block. The outer wall of the limiting post is fitted onto the outer wall of the horizontal plate until the bottom end of the limiting post engages and is installed with the inner wall of the slide plate. The bottom plate is placed on the outer wall of the support plate, so that the outer wall of the protrusion fixed at the bottom end of the bottom plate engages and is installed with the inner wall of the support plate. Therefore, it is easier to better support the driving gear and the driven gear. Attached Figure Description

[0027] The five driving organizations include:

[0028] A drive motor 51 is fixed at its top end to the outer wall of the base 1. A drive gear 52 is coaxially connected to the output end of the drive motor 51. A driven gear 53 is driven by the outer wall of the drive gear 52. A lead screw 54 is fixed at the top end of the driven gear 53. A slide plate 55 is driven by the outer wall of the lead screw 54. Two push plates 56 are provided at the top end of the slide plate 55. The outer walls of the two push plates 56 are fitted with the inner wall of the mold body 3. Two blocks 57 are fixed at the top end of the slide plate 55. The outer walls of the two blocks 57 are matched with the inner walls of the push plates 56. A horizontal plate 58 is provided on the inner wall of the two blocks 57. The outer walls of the two horizontal plates 58 are fitted with the inner walls of the push plates 56. Limiting posts 59 slide on the inner walls of the two horizontal plates 58. The bottom ends of the two limiting posts 59 are matched with the inner walls of the slide plate 55.

[0029] As attached Figure 3 and Figure 4As shown, two support plates 7 are fixed to the outer wall of the base 1. The outer wall of the two support plates 7 is provided with a base plate 8. The base plate 8 is set at the bottom end of the driving gear 52 and the driven gear 53. Two protrusions 9 are fixed to the bottom end of the base plate 8. The outer wall of the two protrusions 9 is matched with the inner wall of the support plate 7, so that the outer wall of the protrusions 9 fixed at the bottom end of the base plate 8 is engaged with the inner wall of the support plate 7, thus facilitating better support for the driving gear 52 and the driven gear 53.

[0030] As attached Figure 2 , Figure 3 and Figure 4 As shown, the lifting mechanism 6 includes:

[0031] The connecting plate 61 is fixed to the outer wall of the base 1 on both sides. A hydraulic pump 62 is fixed to the top of the connecting plate 61. A top block 63 is fixed to the output end of the hydraulic pump 62. The outer wall of the top block 63 is fitted into the middle of the bottom end of the inner wall of the mold body 3, so that the top block 63 pushes the middle of the bottom end of the stamped sheet metal, thereby effectively improving the demolding of the stamped sheet metal by the device.

[0032] Working principle: In use, the outer walls of the two push plates 56 are respectively fitted onto the inner walls of the mold body 3, so that both push plates 56 are installed at the top of the slide plate 55. Then, the inner walls of the push plates 56 match and are installed with the outer walls of the block 57 fixed at the top of the slide plate 55. The outer wall of the horizontal plate 58 is fitted onto one side of the push plates 56, so that the outer wall of the horizontal plate 58 engages and is installed with the inner wall of the block 57. The outer wall of the limiting post 59 is fitted onto the outer wall of the horizontal plate 58 until the bottom end of the limiting post 59 engages and is installed with the inner wall of the slide plate 55. The base plate 8 is placed on the outer wall of the support plate 7, so that the outer wall of the protrusion 9 fixed at the bottom end of the base plate 8 engages and is installed with the inner wall of the support plate 7. This facilitates better support for the drive gear 52 and driven gear 53. The operator controls the drive motor 51 to rotate the drive gear 52, causing the drive gear 52 to transmit power to the driven gear 53. This, in turn, causes the driven gear 53 to drive the lead screw 54 to rotate. During the rotation of the lead screw 54, the slide plate 55 moves up and down, causing the push plate 56 to fit against the inner wall of the mold body 3. This pushes the bottom sides of the stamped sheet metal upwards. The hydraulic pump 62 drives the top block 63 to move up and down, pushing the top block 63 against the center of the bottom end of the stamped sheet metal, thus effectively improving the demolding of the stamped sheet metal.
