Detailed Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] The present utility model provides two technical solutions:

[0027] Figures 1-4 The first implementation manner is shown: A stamping die for a door lock catch mounting plate, including a workbench 1 and a steel bar 4. An installation frame 11 is fixedly installed at a position near the rear side of the top of the workbench 1. A stamping mechanism 2 is arranged outside the installation frame 11 for stamping and demolding the door lock catch mounting plate. The stamping mechanism 2 includes:

[0028] A mold assembly 21, arranged on the top of the workbench 1;

[0029] A driving assembly 22, arranged on the top of the installation frame 11;

[0030] A material pushing assembly 23, arranged at the rear side of the installation frame 11. The material pushing assembly 23 includes a rectangular rod 236 that movably penetrates the outer surface of the installation frame 11. A push plate 237 is fixedly installed on the front side of the rectangular rod 236. A second reciprocating slider 235 is fixedly installed at a position near the rear side of the top of the rectangular rod 236;

[0031] An ejecting assembly 24, arranged at the bottom of the workbench 1. The ejecting assembly 24 includes a connecting plate 241. Four tension springs 242 are fixedly installed on the top of the connecting plate 241. An ejecting rod 243 is arranged inside the tension springs 242.

[0032] The mold assembly 21 includes a connecting rod 211 and a lower mold 216. The connecting rod 211 movably penetrates the top of the installation frame 11. A first reciprocating slider 212 is fixedly installed at the top end of the connecting rod 211. An upper mold 213 is fixedly installed at the bottom end of the connecting rod 211. Four guide rods 215 are fixedly installed on the top of the upper mold 213. The outer walls of the guide rods 215 movably penetrate the inner top of the installation frame 11 and extend upward. A cutting knife 214 is arranged on the outer surface of the upper mold 213. The cutting knife 214 surrounds the periphery of the upper mold 213. The lower mold 216 is fixedly installed at a position near the front inner side of the top of the workbench 1. A relief groove 217 is arranged at a position near the edge of the inner cavity bottom of the lower mold 216.

[0033] The profiling surface of the upper die 213, as well as the chamber of the lower die 216 and the shape of the door lock buckle mounting plate to be stamped, are the same. The guiding rod 215 is provided to guide and limit the upper die 213 during movement, ensuring stability. By providing the relief groove 217, the cutter 214 can be prevented from colliding and interfering with the inner cavity of the lower die 216.

[0034] The driving assembly 22 includes a motor 221 and a first bearing block 223. The motor 221 is fixedly installed at a position near the left side of the top of the mounting frame 11. A driving gear 222 is fixedly installed at the output end of the motor 221. The first bearing block 223 is fixedly installed at a position near the middle of the top of the mounting frame 11. A first rotating shaft 224 is disposed through the shaft hole of the first bearing block 223. A first crankshaft 225 for driving the first reciprocating slider 212 to perform up-and-down reciprocating motion is installed at the front end of the first rotating shaft 224. A driven gear 226 meshing with the driving gear 222 is fixedly installed on the outer wall of the first rotating shaft 224. A first bevel gear 227 is fixedly installed at the rear end of the first rotating shaft 224.

[0035] When the upper die 213 moves upward and separates from the lower die 216, the ejector rod 243 is pushed by the tension spring 242 to jack up the door lock buckle mounting plate. At this time, the door lock buckle mounting plate is higher than the cut of the steel bar 4, avoiding the cut of the steel bar 4 from jamming the door lock buckle mounting plate. And while the upper die 213 moves upward, the push plate 237 will move forward, thereby pushing the door lock buckle mounting plate forward. Under the action of inertia, the door lock buckle mounting plate is pushed into the receiving box 3, thus achieving the function of automatic demoulding and improving the working efficiency.

[0036] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that the pushing component 23 further includes a second bearing block 231 fixedly installed at the rear side of the mounting frame 11. A second rotating shaft 232 is disposed through the shaft hole of the second bearing block 231. A second bevel gear 233 meshing with the first bevel gear 227 is installed at the top end of the second rotating shaft 232. A second crankshaft 234 for driving the second reciprocating slider 235 to perform front-and-back reciprocating motion is installed at the bottom end of the second rotating shaft 232.

[0037] The top end of the tension spring 242 is fixedly connected to the bottom surface of the workbench 1, and the bottom end of the ejector rod 243 is fixedly connected to the top surface of the connecting plate 241. The outer wall of the ejector rod 243 sequentially passes through the bottom surface of the workbench 1 and the lower die 216 and extends into the inner cavity of the lower die 216.

[0038] The connecting plate 241 can be pulled upward by the tension spring 242, so that the ejector rod 243 moves upward, ejecting the stamping part. And the top end of the ejector rod 243 is higher than the bottom surface of the inner cavity of the lower die 216 under normal conditions. When the upper die 213 and the lower die 216 are closed, the upper die 213 will squeeze the ejector rod 243 to move downward, thus not having a negative interference effect on stamping.

[0039] A receiving box 3 is arranged on the front side of the workbench 1, and a guide roller 12 for guiding the steel bar 4 is installed at a position near the left side of the top of the workbench 1.

[0040] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0041] During operation, the steel bar 4 is conveyed from left to right by external traction. By starting the motor 221, the first crankshafts 225 and the first bevel gears 227 at both ends of the first rotating shaft 224 are driven to rotate. When the first crankshaft 225 rotates, the first reciprocating slider 212 makes a reciprocating up and down motion, so that the upper die 213 makes a reciprocating up and down motion. When the first bevel gear 227 rotates, it drives the second bevel gear 233 to rotate. Cooperating with the second crankshaft 234 and the second reciprocating slider 235, the rectangular rod 236 and the push plate 237 make a reciprocating back and forth motion. And when the upper die 213 moves downward, the push plate 237 moves backward. Similarly, when the upper die 213 moves upward, the push plate 237 moves forward. After the upper die 213 moves downward to the lowest position, it will be closed with the lower die 216. And before closing, the steel bar 4 can be cut by the cutter 214 on the periphery of the upper die 213 to obtain a steel sheet. Under the pressure of the closing of the upper die 213 and the lower die 216, the steel sheet forms a door lock buckle mounting plate. After that, when the upper die 213 moves upward and separates from the lower die 216, under the action of the tension spring 242, the ejector rod 243 is pushed to eject the door lock buckle mounting plate. At this time, the door lock buckle mounting plate is higher than the cut of the steel bar 4, avoiding the cut of the steel bar 4 from jamming the door lock buckle mounting plate. And while the upper die 213 moves upward, the push plate 237 will move forward, thus pushing the door lock buckle mounting plate forward. Under the action of inertia, the door lock buckle mounting plate is pushed into the receiving box 3, thus achieving the function of automatic demoulding and improving the work efficiency.
