Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and more specifically to a stamping die that facilitates the replacement of concave and convex dies. Background Technology

[0002] Dies and dies are the "die plates" or "templates" in stamping dies, and the two work together to complete the stamping forming task. They are inseparable and are the key to achieving precise forming in production.

[0003] According to patent publication number CN215032977U, published on 2021-12-07, a car mold for easy replacement of dies and punches is disclosed, including a lower mold plate and an upper mold plate. Protective plates are fixedly connected to the four sides of the upper surface of the lower mold plate. The upper mold plate is movably connected above the lower mold plate. A mold transfer device is movably connected to the upper surface of the lower mold plate near the rear end and behind the protective plates. A die holder is fixedly connected to the upper surface of the lower mold plate. A punch holder is fixedly connected to the lower surface of the upper mold plate above the die holder. Limiting guide sleeves are fixedly connected to the lower surface of the upper mold plate near the four corners. Limiting guide posts are fixedly connected to the upper surface of the lower mold plate near the four corners and below the limiting guide sleeves. A high-pressure nozzle is fixedly connected to the upper surface of the lower mold plate at the front of the rear protective plate at the rear end. An air distribution pipe is fixedly connected to the upper surface of the lower mold plate at the rear end of the rear protective plate. A telescopic device is fixedly connected to the interior of the lower mold near the rear end and on one side of the mold transfer device. A buffer post is fixedly connected to the interior of the lower mold near the rear end and on the other side of the mold transfer device.

[0004] In the prior art, including the aforementioned patent, the material to be stamped is fed into the upper surface of the die holder through the feed port, and then the upper die plate presses down, causing the punch and die holder to squeeze against each other, thereby producing an automotive mold of the required shape. This conventional mold-closing method can effectively stamp out the required product. However, the installation of the punch and die holder usually involves multiple bolts and manual adjustments. Especially for the die holder, in order to accurately close with the punch, the mounting holes need to be manually adjusted and aligned multiple times to ensure the accuracy of installation and the quality of product stamping. However, the method of using multiple bolts is cumbersome and cannot quickly position the die holder, resulting in inconvenient installation. Utility Model Content

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-5As shown, a stamping die that facilitates the replacement of dies and punches includes a die 3 and a punch 6 arranged vertically from bottom to top, a mounting frame 1, and a mounting seat 2 movably disposed on the mounting frame 1 and cooperating with the die 3. The mounting seat 2 is slidably disposed in a groove 13 opened on the mounting frame 1, the die 3 is slidably disposed on the top of the mounting seat 2, and a mounting plate 33 disposed on the die 3 is located on one side of a baffle 15 disposed on the mounting frame 1. The first bolt 8 passing through the mounting plate 33 and the baffle 15 is threadedly rotatably disposed in a threaded groove 24 opened on the mounting seat 2. The mounting base 2 is slidably disposed within the slide groove 13, and the concave mold 3 is slidably disposed on the top of the mounting base 2, thereby quickly limiting and positioning the mounting base 2 and the concave mold 3. Then, the first bolt 8 is passed through the mounting plate 33 and the baffle 15 and threaded into the threaded groove 24, thereby quickly fixing the mounting base 2 and the concave mold 3, thus realizing the rapid fixing and positioning of the concave mold 3 in the convex and concave mold.

[0027] Specifically, in the above technical solution, the punch 6 is mounted on a slidably disposed stamping plate on the mounting bracket 1. The punch 6 slides close to the die 3, thereby closing the punch 6 and the die 3 to achieve stamping.

[0028] As a further technical solution provided by this utility model, the protrusion 21 provided on the mounting base 2 is embedded in the tapered groove 31 opened at the first end of the concave mold 3.

[0029] Specifically, such as Figure 4 As shown, the concave mold 3 slides on the top of the mounting base 2, and then the protrusion 21 on the mounting base 2 is embedded in the tapered groove 31 opened at the first end of the concave mold 3. At this time, the concave mold 3 is further confined to the top of the mounting base 2, which can enhance the fixing strength of the concave mold 3 in the vertical direction.

[0030] Furthermore, the die part 3, the mounting base 2 and the mounting bracket 1 are sequentially provided with corresponding top holes 32, middle holes 22 and bottom holes 14.

[0031] Specifically, the top hole 32, the middle hole 22 and the bottom hole 14 correspond to the punch 6, so that when the punch 6 moves down to punch, it passes through the top hole 32 and the middle hole 22, and then the punched waste is removed along the bottom hole 14.

[0032] Furthermore, the limiting pin 7, which is slidably mounted on the mounting bracket 1, is slidably mounted in the positioning hole 23 opened at the bottom of the mounting base 2.

[0033] Specifically, by sliding the limiting pin 7 within the positioning hole 23, the mounting base 2 is further limited to the mounting bracket 1, thereby enhancing the stability of the mounting base 2.

[0034] Furthermore, the protruding rod 34 fixedly installed on the mounting plate 33 is slidably disposed on the first inclined surface 71 provided on the limiting pin block 7.

[0035] Specifically, the mounting base 2 is attached to the baffle 15, and then the concave mold 3 is slidably set on the top of the mounting base 2 and close to the baffle 15. Then the protruding rod 34 on the concave mold 3 slides on the first inclined part 71 on the limiting pin block 7. At this time, the limiting pin block 7 is squeezed to insert into the positioning hole 23, thereby driving the limiting pin block 7 to slide through the concave mold 3.

[0036] Furthermore, the mounting bracket 1 has an inclined groove 11 connected to the slide groove 13. The mounting groove 12 on the inner walls of the inclined groove 11 on both sides is movably provided with a positioning block 16, and the positioning block 16 is attached to the mounting base 2. A second bolt 17 is movably provided on the positioning block 16.

[0037] Specifically, the mounting base 2 slides along the inclined groove 11 into the slide groove 13. Then, when the mounting base 2 is attached to the baffle 15, it is installed in the mounting groove 12 by the positioning block 16 and fixed to the mounting bracket 1 by the second bolt 17. At this time, the positioning block 16 limits and positions the mounting base 2.

[0038] Furthermore, the fixing block 4, which is slidably mounted on the mounting base 2, is movably mounted in the positioning groove 18 opened on the mounting frame 1.

[0039] Specifically, the fixing block 4 on the mounting base 2 is inserted into the positioning groove 18, thereby further fixing and limiting the mounting base 2 to the mounting frame 1. The limiting pin 7 and the fixing block 4 are respectively movable at the bottom of the mounting base 2 and close to both ends, thereby more stably limiting the mounting base 2.

[0040] Furthermore, the concave mold 3 is movably mounted on the second inclined surface 42 provided on the fixed block 4.

[0041] Specifically, when the concave mold 3 slides on the top of the mounting base 2, the second inclined surface 42 is pressed by the concave mold 3, thereby causing the fixing block 4 to slide obliquely downward and be inserted into the positioning groove 18.

[0042] Furthermore, an adjustment rod 5 is hinged on the mounting base 2, and a pin 43 on the fixing block 4 is movably disposed in the waist groove 52 opened on the adjustment rod 5. A torsion spring 51 is provided on the adjustment rod 5.

[0043] Specifically, the torsion spring 51 is sleeved on the hinge shaft of the adjusting rod 5, and the two ends of the torsion spring 51 are fixedly installed on the adjusting rod 5 and the mounting base 2 respectively. The fixing block 4 has a slot 41, and the pin 43 is fixedly installed on the inner wall of the slot 41. When the fixing block 4 slides downward at an angle, the torsion spring 51 deforms and stores force. When the die part 3 is disengaged from the mounting base 2, the torsion spring 51 deforms and releases the stored force to make the fixing block 4 protrude from the top of the mounting base 2.

[0044] Furthermore, a feed groove 35 is provided on the top of the die part 3.

[0045] Specifically, the stamped part can move along the feed groove 35 and be stamped by the punch 6.

[0046] Working principle: The mounting base 2 is slidably set within the slide groove 13, and the concave mold 3 is slidably set on the top of the mounting base 2, thereby quickly limiting and positioning the mounting base 2 and the concave mold 3. The protruding rod 34 on the concave mold 3 slides on the first inclined surface 71 of the limiting pin 7. At this time, the limiting pin 7 is squeezed to insert into the positioning hole 23, thereby driving the limiting pin 7 to slide within the positioning hole 23 through the concave mold 3, thereby further limiting the mounting base 2 to the mounting frame 1 to enhance the stability of the mounting base 2. At the same time, the concave mold 3 squeezes the second inclined surface 42, thereby causing the fixing block 4 to slide obliquely downward and insert into the positioning groove 18, thereby further fixing and limiting the mounting base 2 to the mounting frame 1. Then, the first bolt 8 passes through the mounting plate 33 and the baffle 15 and is threaded into the threaded groove 24, thereby quickly fixing the mounting base 2 and the concave mold 3, thereby achieving rapid fixing and positioning of the concave mold 3 in the convex and concave mold.

[0047] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
