Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, specifically to an integrated molding die for automotive sunroof stamping parts. Background Technology

[0002] Stamping dies, as important processing equipment in the automotive manufacturing industry, are widely used in the forming process of various automotive parts. In automobile production, to improve driving comfort, many models are equipped with sunroofs. Currently, the production method for automotive sunroof stamping parts typically involves stamping the outer frame of the sunroof and other auxiliary parts separately.

[0003] When stamping automotive sunroof parts, the most common demolding method is manual demolding. This involves using tools to tap the outer surface of the mold to detach the stamped parts from the mold. This method is time-consuming and labor-intensive. Furthermore, after demolding, workers must reinstall the mold for the next stamping operation, resulting in long stamping intervals and low stamping efficiency. Utility Model Content

[0013] Figure 3 This is a schematic diagram of the demolding mechanism in this utility model. Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. However, the specific implementation methods and embodiments described below are for illustrative purposes only and are not intended to limit the present invention.

[0015] See attached diagram. Figures 1 to 3 This embodiment of an integrated molding die for stamping parts for automotive sunroofs includes a frame 1, a stamping cylinder 10 on the top of the frame 1, and a stamping head 11 at the output end of the stamping cylinder 10; a slide rail 12 is provided on the frame 1, a lower die 3 is provided on the slide rail 12, a die cavity 30 is provided on the lower die 3, a demolding hole 31 is provided at the bottom of the die cavity 30, and a demolding mechanism 2 is provided below the demolding hole 1; a driving mechanism is provided on the rear side of the lower die 3.

[0016] Furthermore, the demolding mechanism 2 includes a demolding cavity 20, which is provided with two sets of slide rods 21. A compression spring 22 is provided between the two sets of slide rods 21. A slide plate 23 is provided on the two sets of slide rods 21. One end of the compression spring 22 is fixedly connected to the slide plate 23, and the other end is fixedly connected to the bottom wall of the demolding cavity 20. A push rod 24 is provided on the top of the slide plate 23. The push rod 24 is located below the demolding hole 31.

[0017] Furthermore, a connecting post 25 is provided on one side of the ejector pin 24, and a connecting plate 4 is hinged to one side of the connecting post 25. A rotating shaft 40 is provided at one end of the connecting plate 4, and a connecting arm 41 is provided on one side of the rotating shaft 40. The connecting arm 41 is located outside the lower mold 3, and a retaining ring 42 is provided on the connecting arm 41. An inclined limiting post 5 is provided above the connecting arm 41, and the retaining ring 42 is detachably connected to the inclined limiting post 5.

[0018] Furthermore, the drive mechanism includes a support plate 6, a vertical plate 7 on one side of the support plate 6, a first pulley 70 and a second pulley 71 on the vertical plate 7, a transmission belt between the first pulley 70 and the second pulley 71, a shaft 73 connected to one side of the second pulley 71, a rotating wheel 74 on one side of the connecting shaft 73, a connecting rod 8 on the rotating wheel 74, and a slider 80 at one end of the connecting rod 8; a drive motor 72 is provided on one side of the first pulley 70.

[0019] Furthermore, the top of the support plate 6 is provided with a track 60, the slider 80 is slidably connected to the track 60, the front end of the slider 80 is provided with a fixed shaft 81, and one end of the fixed shaft 81 is detachably connected to the rear side of the lower mold 3.

[0020] The working principle of this utility model is as follows: the first pulley 70 is driven to rotate by the drive motor 72, and the second pulley 71 is driven to rotate by the transmission belt. The second pulley 71 drives the connecting shaft 73 and the rotating wheel 74 to rotate, which in turn drives the connecting rod 8 to move. The connecting rod 8 drives the slider 80 to move back and forth on the track 60, which in turn drives the lower mold 3 to move back and forth on the slide rail 12, which facilitates the assembly and demolding of the lower mold 3 before and after stamping.

[0021] When the lower mold 3 is stamping, the retaining ring 42 on the connecting arm 41 in the demolding mechanism 2 is engaged with the inclined limiting post 5. At this time, the ejector rod 24 is located below the demolding hole 31 and does not contact the stamped part. When demolding is required, the lower mold 3 is moved outward by the drive mechanism. The limiting state of the retaining ring 42 and the inclined limiting post 5 is released. At this time, the compression spring 22 rebounds, the slide plate 23 moves upward along the slide rod 21, and then drives the ejector rod 24 to lift up and extend out of the demolding hole 31, lifting the stamped part for demolding. At the same time, the connecting plate 4 also tilts upward.

[0022] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
