DETAILED DESCRIPTION

[0022] EMBODIMENT

[0023] REFERENCE Figures 1 to 4The stamping die of the automobile door lock comprises a base 1, a support frame 2 fixedly connected to the top end of the base 1, a gas cylinder 3 fixedly connected to the top end of the support frame 2, a stamping die head 4 fixedly connected to the output end of the gas cylinder 3, a positioning groove 8 formed in one side of the top end of the base 1, the stamping die head 4 movably connected with the positioning groove 8, a positioning groove 8 formed in the outer side of the base 1 at the positioning groove 8, a reset assembly 13 arranged in the positioning groove 8, a stress plate 9 connected to one side of the reset assembly 13, the stress plate 9 movably connected in the positioning groove 8, a touch rod 10 fixedly connected to the bottom end of the stress plate 9, a touch switch 11 arranged in the positioning groove 8, one side of the touch rod 10 movably connected with the touch switch 11, a positioning assembly 6 arranged on one side of the output end of the gas cylinder 3, and a prompt lamp 14 arranged on one side of the base 1 and electrically connected with the touch switch 11, so that when the touch switch 11 is triggered, the prompt lamp 14 will immediately light up to send a clear visual signal, so that the staff can quickly detect the fitting state of the die even in a noisy or insufficient light production environment, so that corresponding adjustment measures can be taken in time, and through the above setting, the fitting state of the die can be monitored to avoid waste of production time due to long-time production of unqualified products, and production management personnel can maintain and adjust more quickly.

[0024] Reference Figure 1 The positioning assembly 6 comprises an installation plate 61 fixedly connected to the output end of the gas cylinder 3, and the bottom end of the installation plate 61 is fixedly connected with an extension rod 62 on both sides, and the bottom end of the extension rod 62 is fixedly connected with a positioning plate 63 movably connected with the positioning groove 8 and the stress plate 9.

[0025] Reference Figure 1 The bottom end of the positioning plate 63 is provided with a fitting groove 64 movably connected with the stress plate 9.

[0026] Reference Figure 1 The top end of the installation plate 61 is fixedly connected with a guide rod 7 on both sides, and one side of the guide rod 7 slides through one side of the support frame 2.

[0027] Reference Figure 3The positioning groove 8 has mounting grooves 12 on both sides. The touch switch 11 is installed inside the mounting groove 12, and one side of the touch rod 10 is slidably connected to the mounting groove 12. The mounting groove 12 is used to install the touch switch 11, and the touch rod 10 slides in the mounting groove 12 to contact the touch switch 11.

[0028] refer to Figure 4 The reset assembly 13 includes a reset spring 134, which is installed inside the positioning groove 8. A first fixing block 131 is fixedly connected to one side of the reset spring 134. The first fixing block 131 is slidably connected inside the positioning groove 8. A transmission rod 132 is hinged to one side of the first fixing block 131. A second fixing block 133 is hinged to the side of the transmission rod 132 away from the first fixing block 131. The second fixing block 133 is fixedly connected to the bottom end of the force plate 9. By setting the reset assembly 13, the positioning plate 63 pushes the force plate 9, and the force plate 9 pushes the reset spring 134 to deform. At the same time, the transmission rod 132 transmits power between the first fixing block 131 and the second fixing block 133, causing the first fixing block 131 to slide. This causes the force plate 9 to drive the touch rod 10 to move downward and contact the touch switch 11. Once the force plate 9 is no longer under pressure, the reset spring 134 returns to its original deformation, causing the touch rod 10 to leave the touch switch 11.

[0029] refer to Figure 2 The positioning groove 8 has grooves 135 on both sides inside. The reset spring 134 is fixedly connected inside the groove 135. The first fixing block 131 is slidably connected to the groove 135. The groove 135 is provided to install the reset spring 134 and to allow the first fixing block 131 to slide inside the groove 135.

[0030] Operating principle and advantages: The mold is placed in the mold slot 5, and the cylinder 3 drives the stamping die head 4 to move. Under the action of the guide rod 7, the stamping die head 4 moves stably to avoid deviation, which also facilitates the movement of the positioning plate 63. The extension rod 62 drives the positioning plate 63 to move into the positioning slot 8 and contact the force plate 9. The force plate 9 contacts the fitting groove 64 below the positioning plate 63. At this time, the force plate 9 pushes the return spring 134 to deform it. At the same time, the transmission rod 132 transmits power between the first fixed block 131 and the second fixed block 133, causing the first fixed block 131 to slide, which in turn causes the force plate 9 to drive the contact rod. When the 10 moves downward and contacts the touch switch 11, the indicator light 14 is powered on and illuminated. The operator uses the indicator light 14 to determine whether the punch head is in full contact with the mold groove 5. By promptly identifying and resolving fitting problems, it is possible to prevent and reduce mold damage or machine malfunctions caused by poor mold fitting, which could lead to safety accidents and potential hazards, thus ensuring a safe production environment. Once the pressure plate 9 is no longer under pressure, the return spring 134 returns to its original shape, causing the touch rod 10 to leave the touch switch 11. This ensures that the mold can be restored to its optimal working state before the next operation, reducing the time and effort required for manual reset.
