[0003] The rapid development of the automotive industry has placed higher demands on the quality and production efficiency of automotive parts. As a key component of the vehicle safety system, the design and manufacturing of the inner carrier board of the car door lock directly affects the performance and reliability of the door lock.
[0004] In traditional manufacturing processes, the lower platen of a die for stamping and folding the inner carrier plate of an automotive door lock is stationary, while a pneumatic cylinder drives the upper platen to stamp and fold the inner carrier plate. This long distance between the upper platen and the output end of the cylinder increases the time required for each stamping and folding cycle and reduces stamping and folding accuracy. Therefore, a rapid stamping and folding die for automotive door lock inner carrier plates was proposed to address these issues. Utility Model Content

DETAILED DESCRIPTION
[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figure 1 - Figure 2 The present invention provides an embodiment of a rapid stamping die for folding the inner carrier plate of an automobile door lock, comprising a base 1, a surface of which is fixedly connected upright posts 11, four symmetrically arranged groups of upright posts 11, a surface of which is fixedly connected to a top plate 12, the four symmetrically arranged groups of upright posts 11 being used to connect the top plate 12 to the base 1, providing stable support for the top plate 12, a surface of which is fixedly connected to a cylinder 13, an output shaft of which passes through and is slidably connected to the bottom surface of the top plate 12, an output end of which is fixedly connected to an upper mold plate 2, and the cylinder 13 drives the top plate 12 up and down through its output end, thereby closing the upper mold plate 2 and the lower mold plate 4, completing the stamping and folding of the inner carrier plate. The surface of the base 1 is fixedly connected to telescopic rods 3, four symmetrically arranged groups of telescopic rods 3, the top ends of which are fixedly connected to a lower mold plate 4, the four groups of telescopic rods 3 being used to restrict the position of the lower mold plate 4 and enable the lower mold plate 4 to move vertically along the telescopic rods 3.
[0032] Reference Figure 2 - Figure 3 A connecting assembly 5 is provided between the upper template 2 and the lower template 4. The connecting assembly 5 is used to link the upper template 2 and the lower template 4 so that the upper template 2 and the lower template 4 move toward or away from each other. The connecting assembly 5 includes an inclined plate 1 51, which is hinged on the side wall of the upper template 2. The end of the inclined plate 1 51 is hinged with an inclined plate 2 52. The inclined plate 2 52 is hinged to the side wall of the lower template 4. By changing the angle between the inclined plate 1 51 and the inclined plate 2 52, the position of the upper template 2 and the lower template 4 is changed. A through hole is provided at the hinge of the inclined plate 1 51 and the inclined plate 2 52, and a fixed shaft 53 is rotatably connected in the through hole. The side wall of the base 1 is fixedly connected to a support frame 54, and the side wall of the support frame 54 is fixedly connected to a horizontal plate 55. The side wall of the horizontal plate 55 is provided with a limiting slide 56, and the fixed shaft 53 is slidably connected inside the limiting slide 56. The limiting groove 56 is used to limit the movement of the fixed shaft 53, so that the fixed shaft 53 moves laterally along the inside of the limiting groove 56. When the upper template 2 is driven by the cylinder 13 to move downward, under the limiting action of the limiting groove 56, the fixed shaft 53 remains in the vertical direction, the angle between the inclined plate 1 51 and the inclined plate 2 52 becomes smaller, and the fixed shaft 53 moves in the lateral direction, thereby realizing the relative movement of the upper template 2 and the lower template 4.
[0033] Reference Figure 3 - Figure 4 The surface of the lower template 4 is provided with an ejection component 6, which is used to eject the formed inner carrier plate to facilitate the staff to take it. The ejector assembly 6 includes a groove 61, which is opened on the surface of the lower template 4. An ejector plate 62 is inserted into the interior of the groove 61. The groove 61 is used to place the ejector plate 62. The ejector plate 62 is in contact with the bottom surface of the inner carrier plate. The bottom surface of the ejector plate 62 is fixedly connected to a connecting rod 63. The connecting rod 63 passes through and is slidably connected to the bottom surface of the lower template 4. The bottom end of the connecting rod 63 is fixedly connected to a circular plate 64. The circular plate 64 is elastically connected to the bottom surface of the lower template 4 by a return spring 65. The connecting rod 63 is used to connect the circular plate 64 and the ejector plate 62 together to achieve synchronous movement of the two. The return spring 65 is used to elastically support the connecting rod 63, so that the circular plate 64 and the ejector plate 62 move downward synchronously, and the ejector plate 62 is received in the groove 61. When the upper template 2 and the lower template 4 move away from each other, the circular plate 64 contacts the surface of the base 1, thereby compressing the return spring 65, and the connecting rod 63 and the ejector plate 62 eject the formed inner carrier plate.
[0034] Working Principle: First, the inner carrier plate of the automobile door lock to be stamped is placed on the lower plate 4, ensuring its accurate positioning. Then, the cylinder 13 is activated, and its output shaft begins to move downward, driving the upper plate 2 downward toward the lower plate 4. Driven by the cylinder 13, the upper plate 2 and the lower plate 4 gradually approach each other until they are tightly fitted together, thus stamping and folding the inner carrier plate.
[0035] During the stamping and folding process, as the upper template 2 descends, the angle between the inclined plate 1 51 and the inclined plate 2 52 gradually decreases. The lateral movement of the fixed shaft 53 in the limiting slide groove 56 realizes the relative movement of the upper template 2 and the lower template 4, ensuring the stability and reliability of the mold and improving the accuracy and efficiency of stamping and folding.
[0036] When the stamping and folding operations are completed, the output shaft of the cylinder 13 begins to move upward, driving the upper plate 2 and the lower plate 4 to move in opposite directions. As the upper plate 2 rises, the circular plate 64 contacts the surface of the base 1, the return spring 65 is compressed, and the connecting rod 63 and the ejector plate 62 eject the formed inner carrier plate from the lower plate 4, making it easy to remove the formed inner carrier plate for the next processing or assembly.
[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
