Description

Technical Field

[0001] This utility model relates to the field of headrest counterweight manufacturing technology, specifically to a headrest counterweight forging and pressing mold. Background Technology

[0002] A headrest counterweight forging and pressing die is a specialized tool or equipment used to manufacture counterweights. It is typically made of metal and uses a pressure forming process to press the material into counterweights of specific shapes and sizes. Usually, heated metal powder is poured into a feeding shovel via an external feeding device. The shovel then pours the metal powder into the lower die. A hydraulic system controls the piston rod below the hydraulic cylinder to move downwards, causing the upper die below the movable block to move downwards until the upper die presses the metal powder in the lower die into shape.

[0003] To avoid affecting the closing of the upper and lower dies, a certain distance is left between the end of the feeding shovel near the lower die and the forming hole of the lower die. However, when pouring metal powder, some powder will fall onto the outside of the forming hole on the upper surface of the lower die, causing material waste and affecting the forming quality and subsequent die closing. Therefore, a forging and pressing die for the headrest counterweight is required to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a forging and pressing mold for headrest counterweights to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model is a forging and pressing mold for a headrest counterweight, comprising: A briquetting machine, comprising a worktable, a lower die, an upper die, and a feeding shovel. The lower die is fixed in the middle of the worktable, the upper die is fixed below a movable plate, and the movable plate is movably connected above the worktable. One end of the feeding shovel is rotatably connected to one end above the lower die, and the other end is movably connected to one end above the worktable via a hydraulic rod. The leak-proof component includes an inner shovel, a limiting block, a limiting plate, a first triangular block, a limiting hole, a support column, and a second triangular block. The inner shovel is placed inside the feeding shovel, and its outer side is in contact with the inner wall of the feeding shovel. The upper end of the limiting block is fixed to the lower end of the inner shovel, the limiting plate is fixed to both sides of the limiting block, the first triangular block is fixed to the lower end of the limiting block, the limiting hole is opened in the middle of the feeding shovel, the lower end of the support column is fixed to one end above the workbench, and the second triangular block is fixed to the upper end of the support column.

[0005] Furthermore, the leak-proof assembly also includes an opening and a roller. The opening is formed on the inner bottom surface of the feeding shovel, the roller is rotatably connected in the opening, and the inner shovel is placed on the roller.

[0006] Furthermore, the limiting block is inserted into the limiting hole, and the limiting plate is located at the lower end of the feeding shovel.

[0007] Furthermore, the first triangular block is movably connected above the second triangular block, with the first triangular block facing downwards and the second triangular block facing upwards.

[0008] Furthermore, the briquetting machine also includes a base, which is fixed to the ground, and the worktable is fixed to the upper part of the base.

[0009] Furthermore, it also includes a splash-proof assembly, which includes a T-shaped connecting rod, a torsion spring, a side baffle, a through hole, and a rear baffle. One end of the T-shaped connecting rod is fixed to both sides of the end of the feeding shovel away from the lower mold. The through hole is opened at the lower end of the side baffle and is sleeved on the T-shaped connecting rod. The torsion spring is sleeved on the T-shaped connecting rod, with one end fixed to the side baffle and the other end fixed to the T-shaped connecting rod. The rear baffle is fixed to the end of the feeding shovel away from the lower mold.

[0010] Furthermore, the side baffle is rotatably connected to the T-shaped connecting rod, and the side edge of the side baffle is movably connected to the side edge of the upper movable plate of the upper mold.

[0011] This utility model has the following beneficial effects: This invention, through the inclusion of a leak-proof component, prevents metal powder from falling outside the forming hole of the lower mold. When the piston rod of the hydraulic cylinder moves upward, it lifts the rear end of the feeding shovel, causing the end of the feeding shovel on the lower mold to rotate. As the feeding shovel is lifted, the inner shovel slides along the inner bottom surface of the feeding shovel, causing the roller in the opening to rotate. Simultaneously, it causes the limiting block to move along the limiting hole until it reaches the other end of the limiting hole. The limiting plate then moves against the lower bottom surface of the feeding shovel, and the end of the inner shovel on the lower mold extends into the forming hole of the lower mold. The metal powder in the inner shovel falls into the forming hole of the lower mold. After feeding is completed, the piston rod moves downward, and the feeding shovel falls. When the first triangular block moves to the second triangular block, as the feeding shovel falls, the first triangular block moves along the inclined surface of the second triangular block, thereby causing the limiting block to move in the opposite direction along the limiting hole, moving the inner shovel into the feeding shovel until it is completely inside. This design prevents metal powder from falling outside the forming hole of the lower mold, causing material waste and affecting the forming quality and subsequent mold closing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-5 As shown, this utility model is a forging and pressing mold for a headrest counterweight, comprising: The briquetting machine includes a worktable 11, a lower die 12, an upper die 13, and a feeding shovel 14. The lower die 12 is fixed in the middle of the worktable 11, the upper die 13 is fixed below the movable plate, and the movable plate is movably connected to the upper part of the worktable 11. One end of the feeding shovel 14 is rotatably connected to the upper part of the lower die 12, and the other end is movably connected to the upper part of the worktable 11 through a hydraulic rod. The briquetting machine also includes an equipment base 10, which is fixed on the ground, and a worktable 11 is fixed on the upper part of the equipment base 10; The equipment base 10 and the workbench 11 provide support, the lower mold 12 and the upper mold 13 are used for forming the counterweight block, and the feeding shovel 14 is used for feeding material into the lower mold 12.

[0018] The leak-proof component includes an inner shovel 20, a limiting block 21, a limiting plate 22, a first triangular block 23, a limiting hole 24, a support column 27, and a second triangular block 28. The inner shovel 20 is placed inside the feeding shovel 14, and its outer side is in contact with the inner wall of the feeding shovel 14. The upper end of the limiting block 21 is fixed to the lower end of the inner shovel 20. The limiting plate 22 is fixed to both sides of the limiting block 21. The first triangular block 23 is fixed to the lower end of the limiting block 21. The limiting hole 24 is opened in the middle of the feeding shovel 14. The lower end of the support column 27 is fixed to one end above the workbench 11. The second triangular block 28 is fixed to the upper end of the support column 27. The leak-proof assembly also includes an opening 25 and a roller 26. The opening 25 is formed on the inner bottom surface of the feeding shovel 14, and the roller 26 is rotatably connected in the opening 25. The inner shovel 20 is placed on the roller 26. The limiting block 21 is inserted into the limiting hole 24, and the limiting plate 22 is located at the lower end of the feeding shovel 14; The first triangular block 23 is movably connected above the second triangular block 28, with the first triangular block 23 facing downwards and the second triangular block 28 facing upwards. The inner shovel 20 is used for feeding. The limiting block 21, the limiting plate 22 and the limiting hole 24 play a limiting role to prevent the inner shovel 20 from sliding out of the feeding shovel 14. The first triangular block 23 and the second triangular block 28 play a guiding role. The opening 25 is used to install the roller 26. The roller 26 can reduce the frictional resistance when the inner shovel 20 moves. The support column 27 plays a supporting role.

[0019] Working principle: When the piston rod of the hydraulic cylinder at one end of the workbench 11 moves upward, it lifts the rear end of the feeding shovel 14, and the end of the feeding shovel 14 located on the lower mold 12 rotates accordingly. After the feeding shovel 14 is lifted, the inner shovel 20 slides along the inner bottom surface of the feeding shovel 14, causing the roller 26 in the opening 25 to rotate. At the same time, it causes the limiting block 21 to move along the limiting hole 24 until the limiting block 21 moves to the other end of the limiting hole 24. The limiting plate 22 moves against the lower bottom surface of the feeding shovel 14, and the end of the inner shovel 20 located on the lower mold 12 extends into the forming hole of the lower mold 12. The metal powder in the inner shovel 20 falls into the lower mold 12. After feeding is completed, the piston rod moves down and the feeding shovel 14 falls. When the first triangular block 23 moves to the second triangular block 28, as the feeding shovel 14 falls, the first triangular block 23 moves along the inclined surface of the second triangular block 28, thereby driving the limiting block 21 to move in the opposite direction along the limiting hole 24, and driving the inner shovel 20 to move into the feeding shovel 14 until it is completely moved into the feeding shovel 14. At this time, the piston rod of the hydraulic cylinder at the upper end of the worktable 11 moves down, driving the movable plate to move down. The lower end of the upper mold 13 below the movable plate moves into the forming hole in the middle of the lower mold 12, pressing the metal powder into a block.

[0020] This step prevents metal powder from falling outside the forming hole of the lower mold 12, thus avoiding material waste and affecting the forming quality and subsequent mold closing.

[0021] Please see Figure 2-3 , Figure 6 As shown, this embodiment, based on the above embodiment, further includes: The splash-proof assembly includes a T-shaped connecting rod 30, a torsion spring 31, a side baffle 32, a through hole 33, and a rear baffle 34. One end of the T-shaped connecting rod 30 is fixed to both sides of the end of the feeding shovel 14 away from the lower mold 12. The through hole 33 is opened at the lower end of the side baffle 32 and is sleeved on the T-shaped connecting rod 30. The torsion spring 31 is sleeved on the T-shaped connecting rod 30, with one end fixed to the side baffle 32 and the other end fixed to the T-shaped connecting rod 30. The rear baffle 34 is fixed at the end of the feeding shovel 14 away from the lower mold 12. The side baffle 32 is rotatably connected to the T-shaped connecting rod 30, and the side of the side baffle 32 is movably connected to the side of the upper movable plate of the upper mold 13. The T-shaped connecting rod 30 facilitates the rotation of the side baffle 32, the torsion spring 31 has a reset function, the side baffle 32 and the rear baffle 34 have a blocking function, and the through hole 33 facilitates the side baffle 32 to be fitted onto the T-shaped connecting rod 30.

[0022] Working principle: An external feeding device suspends metal powder above the feeding shovel 14 and feeds it into the feeding shovel 14. The metal powder falling onto the feeding shovel 14 is blocked by the side baffle 32 and the rear baffle 34 and will not fall outside the feeding shovel 14. When the end of the feeding shovel 14 away from the lower mold 12 moves upward, it drives the side baffle 32 and the rear baffle 34 to move upward. As the feeding shovel 14 rotates and moves upward, the side baffle 32 is blocked by the movable plate above the upper mold 13 and rotates around the T-shaped connecting rod 30. After the metal powder falls into the forming hole of the lower mold 12, the feeding shovel 14 falls down, and the side baffle 32 is reset under the action of the torsion spring 31.

[0023] This step prevents metal powder from splashing onto the outside of the feeding shovel 14 when the external feeding device is feeding metal powder to the feeding shovel 14.
