[0002] A blind hole nut is a special type of nut with a blind hole structure inside, lacking a through hole. This design allows the blind hole nut to be installed from one side, making it suitable for applications requiring unilateral operation or where space is limited. Blind hole nuts typically have good load-bearing capacity and fastening effect, and are widely used in electronic equipment, instruments, vehicles, and other fields. The blind hole nut embedded injection molding structure is a manufacturing process that embeds a blind hole nut into a plastic product. It combines injection molding with the fastening function of a nut and is often used in compact applications requiring unilateral installation. However, existing blind hole nut embedded injection molding structures require manual removal of the workpiece after molding, which is inconvenient and difficult to perform. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a blind hole nut embedding injection structure, which effectively solves the problem that the existing blind hole nut embedding injection structure requires manual removal of the workpiece after molding, which is very inconvenient and difficult to operate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a blind hole nut embedding injection structure, comprising a worktable, a lower mold fixedly installed in the middle of the top of the worktable, a support frame fixedly installed on one side of the top of the worktable, a drive cylinder fixedly installed on the top of the support frame, the transmission end of the drive cylinder extending into the interior of the support frame and fixedly installed with an upper mold, an injection tube fixedly installed on one side of the upper mold, a demolding template provided inside the lower mold, two slots opened on the top of the demolding template, and a blind hole nut body inserted into each of the two slots, an installation groove opened on one side of the upper surface of the worktable, and a transmission component provided on the top of the upper mold, the transmission component being connected to the demolding template in a transmission manner, when the upper mold moves upward, the power is output to the demolding template through the transmission component, causing the demolding template to move upward and lift for demolding.

[0005] Preferably, limit rods are fixedly installed on both sides of the top of the upper mold, and limit holes are opened on both sides of the top of the support frame, with the two limit rods inserted into the two limit holes.

[0006] Preferably, the transmission assembly includes a support arm, which is fixedly installed on the top of the upper mold. A connecting rod is fixedly installed on the lower part of one end of the support arm. The bottom end of the connecting rod extends into the interior of the mounting groove and is fixedly installed with a rack. A gear is meshed on one side of the rack, and one side of the gear is rotatably connected to the inner wall of the mounting groove through a shaft seat.

[0007] Preferably, a slider is fixedly installed on the other side of the rack, and a groove is formed on the inner wall of one side of the mounting groove, and the slider is slidably installed inside the groove.

[0008] Preferably, a rotating shaft is fixedly installed on the other side of the gear. The surface of the rotating shaft is rotatably connected to the inside of the worktable through a bearing. A threaded rod is fixedly installed at one end of the rotating shaft. A positioning frame is rotatably installed at one end of the threaded rod.

A spring is sleeved on the surface of the movable rod, and the two ends of the spring are fixedly connected to the inner top of the worktable and the top of the inclined block, respectively.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During demolding, the operator starts the drive cylinder to move the upper mold upward and open. When the upper mold moves upward, it causes the two limit rods to slide inside the two limit holes, which increases the stability of the upper mold movement. When the upper mold moves upward, it drives the connecting rod to move upward through the support arm. When the connecting rod moves upward, it drives the rack to move upward. When the rack moves upward, it drives the slider to slide inside the slide groove, which increases the stability of the rack movement. When the rack moves upward, it drives the gear to rotate along the shaft seat. When the gear rotates, it drives the rotating shaft to rotate inside the bearing. When the rotating shaft rotates, it drives the threaded rod to rotate along the positioning frame. When the threaded rod rotates, it drives the mounting table to move through the threaded sleeve.

[0012] When the mounting platform moves, the fixed rod drives the sliding sleeve to slide on the surface of the sliding rod, which increases the stability of the mounting platform during movement. When the mounting platform moves, it drives the push bar to move and pushes the inclined block upward. When the inclined block moves upward, it drives the moving rod to move upward and simultaneously compresses the spring to contract, so that the moving rod has an elastic reset effect. When the moving rod moves upward, it drives the demolding template to move upward and pushes out the manufactured workpiece, thereby quickly achieving demolding. This allows the blind hole nut embedded injection structure to be quickly demolded after molding without manual intervention, thus increasing work efficiency. Attached Figure Description
