[0005] The purpose and effect of this utility model of a hardware fitting forming device with a rapid ejection function are achieved by the following specific technical means:

[0006] A hardware fitting forming device with a rapid ejection function includes a mounting base plate, a control module and a safety light curtain;

[0007] The mounting base plate has a mounting groove on its top, and a mold is mounted on the top of the mounting base plate.

[0026] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0027] like Figures 1 to 4 As shown, the present invention proposes a hardware fitting forming device with a rapid ejection function, which includes a mounting base plate 11, a control module 12 and a safety light curtain 13. The control module 12 is electrically connected to the safety light curtain 13 and an external power supply device.

[0028] The mounting base plate 11 serves as the foundation structure of the device, with a mounting groove on its top to accommodate the lever assembly, providing stable support for the mechanical transmission of the entire device. The control module 12 is installed in the mounting slot at the top of the mounting frame 14, responsible for regulating the operation of the device. The control module 12 can be an LCD1602 model. Safety light curtains 13 are symmetrically distributed on the left and right sides of the mounting frame 14, forming a tight safety barrier by emitting and receiving infrared beams. When personnel or objects accidentally enter the protected area, the safety light curtain 13 will quickly detect the abnormal situation of beam obstruction and immediately send an emergency signal to the control module 12. Upon receiving the signal, the control module 12 will immediately initiate an emergency braking procedure, stopping the device in a very short time, effectively preventing accidents. The safety light curtain 13 can be a GM20-4 model, providing reliable protection for equipment operation and personnel safety.

[0029] The mounting frame 14 is connected to the side of the support back plate 16, and the top of the back plate extends into a support top plate 17. The hydraulic cylinder 18, drive motor 19, and gear assembly are all mounted on the support top plate 17. The support top plate 17 and the support back plate 16 provide stable support for the hydraulic cylinder 18 and drive motor 19. The drive motor 19 is fixed by the support frame 21, and its output end is connected to the gear assembly. The drive motor 19 and the hydraulic cylinder 18 are electrically connected to an external power supply to provide power for the operation of the device.

[0030] like Figures 2 to 4 As shown, the lever assembly consists of a lever plate 22, a rotating shaft 23, a connecting seat 24, a connecting rod 25, and a top column 26. The mounting base plate 11 has a movable through slot corresponding to one end of the lever plate 22. This slot allows one end of the lever plate 22 to move up and down, while the other end is limited by the mounting base plate 11, causing only one end to tilt upwards. The lever plate 22 can rotate through the mounting through hole via the rotating shaft 23. The connecting seat 24 is embedded in the grooves at both ends of the lever plate 22. The connecting seat 24 is movably connected to the top column 26 via the connecting rod 25. Limiting grooves on both sides constrain the range of motion of the connecting rod 25. When one end of the lever plate 22 is subjected to force, the connecting rod 25 pushes and pulls the top column 26, causing it to move vertically along the limiting through holes of the mounting frame 14 and the shelf 15, thus ejecting the metal parts formed in the mold 28.

[0031] The shelf 15, mold fixing frame 27, and mold 28 form the molding working area. The limiting through holes on the shelf 15 and mounting frame 14 correspond to the ejector pins 26, guiding the movement of the ejector pins 26. The mold fixing frame 27 is detachably installed at one end of the shelf 15, facilitating the replacement of molds 28 of different specifications; the ejector molds 29, which are locked at the top of one set of ejector pins 26, are detachable, adaptable to various mold structures 28, and demolding is completed under the action of the lever assembly.

[0032] like Figures 1 to 2 As shown, the top support plate 17 has a rotating through slot, in which the rotating support plate 31 is placed, and the hydraulic cylinder 18 is fixed by its limiting slot. The output end of the hydraulic cylinder 18 is connected to the connecting plate 32, which can rotate with the rotating support plate 31 to drive the connecting plate 32 to rotate, thus meeting the requirements of different processes such as extrusion molding and ejection demolding.

[0033] The limiting through holes at the top of the connecting plate 32 and the rotating support plate 31 are respectively used to install the extrusion rod 33 and the feeding pipe 34. One end of the extrusion rod 33 is connected to the extrusion die 35, and under the drive of the hydraulic cylinder 18, it applies pressure to the material in the die 28 to form it. The feeding pipe 34 is connected to the corrugated pipe 37 through the connecting pipe 36. The flexibility of the corrugated pipe 37 allows it to extend and retract to a certain extent to ensure that the material can be stably conveyed into the die 28 when the hydraulic cylinder 18 extends and retracts.

[0034] A support plate 41 is installed in the limiting slot on one side of the connecting plate 32, and one end of the support plate 41 is connected to the ejector rod 42. When the hydraulic cylinder 18 rotates to press down above the ejector column 26, the ejector rod 42 pushes the ejector column 26 to move, converting the pressure of the hydraulic cylinder 18 into ejection power, which, together with the lever assembly, achieves rapid demolding.

[0035] The gear assembly consists of a first gear 38 and a second gear 39, which are responsible for power transmission and direction change. The first gear 38 is mounted on the rotating support plate 31, and the second gear 39 is installed at the output end of the drive motor 19, with the two meshing with each other. When the drive motor 19 is running, the second gear 39 drives the first gear 38 to rotate, which in turn drives the rotating support plate 31 and the hydraulic cylinder 18 to rotate. This causes the hydraulic cylinder 18 to position the functional parts on the connecting plate 32 to their respective positions, ensuring the smooth operation of processes such as extrusion and demolding.

[0036] The specific usage and function of this embodiment are as follows:

[0037] When using this device, the operator first sets parameters such as the speed of the drive motor 19 and the pressure of the hydraulic cylinder 18 through the control module 12, and then feeds the material into the mold 28 through the corrugated pipe 37, connecting pipe 36 and feeding pipe 34. The drive motor 19 starts, and drives the rotating support plate 31 through the gear assembly, causing the hydraulic cylinder 18 to rotate, moving the extrusion rod 33 and the extrusion mold 35 above the mold 28. The hydraulic cylinder 18 drives the extrusion rod 33 to press down, completing the forming of the hardware parts.

[0038] After molding is complete, the drive motor 19 restarts, adjusting the position of the hydraulic cylinder 18 so that the ejector rod 42 aligns with the ejector column 26. The hydraulic cylinder 18 presses down on the ejector rod 42, and the lever plate 22, using the rotating shaft 23 as a fulcrum, leverages the other end of the ejector column 26 to push the ejector mold 29 out of the molded part. The safety light curtain 13 monitors the entire process; once it senses a foreign object entering the danger zone, it immediately transmits a signal to the control module 12 to stop the equipment and prevent accidents. The entire process is automated, significantly improving production efficiency and safety.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
