Description

Technical Field

[0001] This utility model belongs to the field of processing mold technology, specifically a stamping processing mold for automobile cover plate production. Background Technology

[0002] The car cover is a ring-shaped cover structure. During the production and processing of the car cover, a stamping die is used for processing and shaping. The ring-shaped cover structure can be formed by the cooperation of the upper and lower dies during the stamping process.

[0003] Existing stamping dies have relatively complete structures and functions, which can meet basic usage requirements, but the following problems still exist:

[0004] In actual use, the upper die performs a stamping operation with the lower die through transmission components (hydraulic rods, etc.). During this process, the upper die is very prone to vibration due to the vibration of the transmission components, which in turn causes the upper die and lower die to shift in position during stamping. Moreover, the upper die exerts a large stamping force on the lower die during stamping, which will aggravate wear. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a stamping die for automobile cover production. It solves the problem that in actual use, the upper die is easily vibrated by the vibration of the transmission component when it performs stamping operation with the lower die through the transmission component, which leads to the positional displacement of the upper die and the lower die during stamping. In addition, the upper die exerts a large stamping force on the lower die during stamping, which will aggravate the wear.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for producing an automobile cover plate, comprising an upper die and a lower die. An upper mounting plate is fixedly connected to the top of the upper die, and a lower mounting plate is fixedly connected to the bottom of the lower die. A guiding and cleaning structure is provided between the upper and lower mounting plates, and a guiding and buffering structure is provided between the upper and lower dies. The guiding and cleaning structure includes a fixed cylinder, the top of which is fixedly connected to the bottom of the upper mounting plate. A sliding rod is fixedly connected to the top of the lower mounting plate and slidably disposed on the inner wall of the fixed cylinder. The guiding and buffering structure includes a guide rod, the top of which is fixedly connected to the bottom of the upper die.

[0009] As a further embodiment of this utility model: an annular retaining frame is fixedly connected to the connection between the outer surface of the fixed cylinder and the sliding rod, and a semi-annular retaining block is engaged with the inner wall of the annular retaining frame.

[0010] As a further embodiment of this utility model: the inner wall of the annular card frame is provided with a first screw hole, and one side of the semi-annular card block is provided with a second screw hole, and the inner walls of the first screw hole and the second screw hole are threadedly connected with a threaded card rod.

[0011] As a further embodiment of this utility model: a sponge ring block is fixedly connected to one side of the semi-ring block, and a separation groove is provided on one side of the sponge ring block.

[0012] As a further embodiment of this utility model: a circular groove is provided on the top of the lower mold, and a rectangular through groove is provided on one side of the circular groove.

[0013] As a further embodiment of this utility model: a fixed rod is fixedly connected to the bottom of the circular groove, a sliding cylinder is slidably connected to the top of the fixed rod, a buffer spring is sleeved on the outer surface of the fixed rod, and the two ends of the buffer spring are fixedly connected to the outer surface of the sliding cylinder and the inner wall of the circular groove, respectively.

[0014] As a further embodiment of this utility model: a receiving round block is fixedly connected to the top of the outer surface of the sliding cylinder, and a pressing round block is fixedly connected to the bottom end of the guide rod.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This automotive cover plate stamping die, by setting a guiding and cleaning structure, can guide the upper die during the stamping process of the upper die and the lower die under the action of the fixed cylinder and the sliding rod. This allows the upper die and the lower die to be stamped stably, avoiding the upper die from positional displacement with the lower die due to the vibration of the transmission components. This makes the stamping process between the upper die and the lower die more accurate and prevents easy displacement.

[0018] 2. The stamping die for the production of the car cover plate, by setting an annular retaining frame and a semi-annular retaining block, can cooperate with the first screw hole, the second screw hole, and the threaded retaining rod to fix the sponge ring block. This allows the sponge ring block to clean the outer surface of the sliding rod during the movement of the fixed cylinder, so that when the fixed cylinder slides on the outer surface of the sliding rod, impurities will not adhere to the outer surface of the sliding rod and affect the sliding.

[0019] 3. The stamping die for producing the car cover plate has a guide and buffer structure. Under the action of the guide rod, the pressing block can cooperate with the receiving block, thereby driving the sliding cylinder to slide on the outer surface of the fixed rod, which in turn causes the buffer spring to deform and thus buffer.

[0026] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0027] like Figure 1-5As shown, this utility model provides a technical solution: a stamping die for producing an automobile cover plate, including an upper die 1 and a lower die 2. The top of the upper die 1 is fixedly connected to an upper mounting plate 3, and the bottom of the lower die 2 is fixedly connected to a lower mounting plate 4. The upper die 1 is connected to other components through the upper mounting plate 3, and the lower die 2 is connected to other components through the lower mounting plate 4. A guide cleaning structure 5 is provided between the upper mounting plate 3 and the lower mounting plate 4, and a guide buffer structure 6 is provided between the upper die 1 and the lower die 2. The guide cleaning structure 5 includes a fixed cylinder 51, the top of which is fixedly connected to the bottom of the upper mounting plate 3. A sliding rod 52 is fixedly connected to the top of the lower mounting plate 4. The sliding rod 52 can slide on the inner wall of the fixed cylinder 51, thereby providing guidance. The sliding rod 52 is slidably disposed on the inner wall of the fixed cylinder 51. The guide buffer structure 6 includes a guide rod 61, the top of which is fixedly connected to the bottom of the upper die 1. The guide rod 61 can cooperate with other components for guidance.

[0028] Specifically, such as Figures 2-3 As shown, an annular retaining frame 53 is fixedly connected to the connection between the outer surface of the fixed cylinder 51 and the sliding rod 52. A semi-annular retaining block 54 is engaged with the inner wall of the annular retaining frame 53. The semi-annular retaining block 54 can be engaged and fixed with the annular retaining frame 53. A first screw hole 55 is provided on the inner wall of the annular retaining frame 53. A second screw hole 56 is provided on one side of the semi-annular retaining block 54. A threaded retaining rod 57 is threadedly connected to the inner wall of the first screw hole 55 and the second screw hole 56. The threaded retaining rod 57 can cooperate with the first screw hole 55 and the second screw hole 56 to fix the semi-annular retaining block 54. A sponge ring block 58 is fixedly connected to one side of the semi-annular retaining block 54. The sponge ring block 58 can clean the outer surface of the sliding rod 52. A separation groove 59 is provided on one side of the sponge ring block 58. The separation groove 59 allows the two ends of the sponge ring block 58 to be separated, thereby facilitating the disassembly and assembly of the sponge ring block 58.

[0029] Specifically, such as Figure 4 and Figure 5 As shown, a circular groove 63 is provided on the top of the lower mold 2, and a rectangular through groove 64 is provided on one side of the circular groove 63. A fixed rod 65 is fixedly connected to the bottom of the circular groove 63, and a sliding cylinder 66 is slidably connected to the top of the fixed rod 65.

The two ends of the buffer spring 68 are fixedly connected to the outer surface of the sliding cylinder 66 and the inner wall of the circular groove 63, respectively. A receiving block 67 is fixedly connected to the top of the outer surface of the sliding cylinder 66, and a pressing block 62 is fixedly connected to the bottom of the guide rod 61. The pressing block 62 can press down against the receiving block 67, and thus work with the buffer spring 68 to buffer.

[0030] The working principle of this utility model is as follows:

[0031] S1. Engage the semi-ring block 54 with the annular frame 53. At this time, engage and fix the threaded rod 57 with the first threaded hole 55 and the second threaded hole 56. At this time, the upper mold 1 and the lower mold 2 are stamping. At this time, the sliding rod 52 will slide on the inner wall of the fixed cylinder 51.

[0032] S2. During the sliding process of the fixed cylinder 51, it can drive the sponge ring block 58 to move, so that the sponge ring block 58 can slide on the outer surface of the sliding rod 52, thereby cleaning the outer surface of the sliding rod 52 and preventing impurities adhering on the sliding rod 52 from affecting the sliding of the fixed cylinder 51.

[0033] S3. At this time, the guide rod 61 can drive the pressing block 62 to contact and press down with the receiving block 67, which in turn can drive the sliding cylinder 66 to slide on the outer surface of the fixed rod 65, which can then cooperate with the buffer spring 68 to deform and thus buffer.
