Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a quick-change device for stamping dies. Background Technology

[0002] Stamping is a pressure processing method that uses a die mounted on a press to apply pressure to a material at room temperature, causing it to separate or plastically deform, thereby obtaining the desired part. Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Different dies need to be changed when dealing with different forming structures in stamping.

[0003] However, when stamping parts with different structures, it is necessary to change the mold. The current mold requires a large number of bolts for installation, which makes the installation and disassembly time-consuming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-change device for stamping dies, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a quick-change device for stamping dies, including an upper stamping seat and a lower stamping seat. A lower die chamber is installed above the lower stamping seat. A die-moving groove is opened inside the lower die chamber. A sealing plate is provided on one side of the lower die chamber. A hinge is installed between one end of the sealing plate and the lower die chamber. A latch is installed on the other end of the sealing plate. A pressing bolt is provided inside the hinge. A limit stop is installed on the upper surface of the lower stamping seat at the end of the lower die chamber away from the pressing bolt. Dies are arranged in an array inside the die-moving groove. A die limiting hole is opened on the lower surface of the die. A bottom limiting hole is opened on the lower surface of the lower stamping seat.

[0006] As a further improvement of this utility model: the upper surface of the lower stamping seat is provided with a mounting groove corresponding to the position of the limiting block, and the outer end of the limiting block is provided with an L-shaped buckle above the lower stamping seat.

[0007] As a further embodiment of this utility model: a guide groove is installed on the upper surface of the lower die chamber, a guide rod is connected between the lower stamping seat and the upper stamping seat, and an upper die is installed on the lower surface of the upper stamping seat.

[0008] As a further embodiment of this utility model: the sealing plate is rotatably connected to the lower mold chamber via the hinge, and the extrusion bolt is rotatably connected to the hinge by engagement.

[0009] As a further embodiment of this utility model: the mold and the mold groove are limited to slide, and the inner diameter of the bottom limiting hole is the same as the inner diameter of the mold limiting hole.

[0010] As a further improvement of this utility model: a spring is installed below the L-shaped buckle inside the lower stamping seat, and a limit slider is installed on the lower surface of the limit block inside the mounting slot.

[0011] As a further improvement of this utility model, the upper stamping seat is movably connected to the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By applying torque to the extrusion bolts, multiple molds inside the mold groove are compressed and contacted with the limiting blocks. The positioning bolts can be inserted into the mold limiting holes on the lower surface of the outermost mold, thus reducing the number of positioning bolts used to fix the mold. When changing the mold, the replaced mold can be inserted into the mold groove at one end of the sealing plate, allowing for quick replacement of the mold in the rear position.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-4 As shown, this embodiment provides a quick-change device for stamping dies, including an upper stamping base 1 and a lower stamping base 2. A lower die chamber 3 is installed above the lower stamping base 2. A die-moving groove 301 is opened inside the lower die chamber 3. A sealing plate 302 is provided on one side of the lower die chamber 3. A hinge 303 is installed between one end of the sealing plate 302 and the lower die chamber 3. The sealing plate 302 is rotatably connected to the lower die chamber 3 through the hinge 303. A latch is installed on the other end of the sealing plate 302. A pressing bolt 30 is provided inside the hinge 303. 4. The extrusion bolt 304 is engaged and rotated with the hinge 303. The end of the lower die chamber 3 away from the extrusion bolt 304 is equipped with a limit stop 7 on the upper surface of the lower stamping seat 2. The die 305 is arranged in an array inside the die groove 301. The die 305 slides in a limited manner with the die groove 301. The lower surface of the die 305 is provided with a die limiting hole 306. The lower surface of the lower stamping seat 2 is provided with a bottom limiting hole 307. The inner diameter of the bottom limiting hole 307 is the same as the inner diameter of the die limiting hole 306.

[0021] like Figure 2-3 As shown, in this embodiment, the upper surface of the lower stamping seat 2 is provided with a mounting groove 201 corresponding to the position of the limiting block 7. The lower surface of the limiting block 7 is installed with a limiting slider inside the mounting groove 201. An L-shaped buckle 202 is installed above the lower stamping seat 2 at the outer end of the limiting block 7. A spring is installed below the L-shaped buckle 202 inside the lower stamping seat 2. A guide groove 4 is installed on the upper surface of the lower mold chamber 3. A guide rod 6 is connected between the lower stamping seat 2 and the upper stamping seat 1. The upper stamping seat 1 is movably connected to the guide rod 6. An upper mold 5 is installed on the lower surface of the upper stamping seat 1.

[0022] The working principle of this utility model is as follows: When bending a large number of parts, stamping is usually used. The upper stamping die for these parts can be the same as the outer diameter structure of the lower die. The difference lies in the internal structure. Therefore, the die groove 301 set inside the lower die chamber 3 can be used to insert the die 305 of the same structure into one end of the die groove 301. After the L-shaped buckle 202 is pressed into the lower stamping seat 2, the slider of the limiting block 7 is inserted into the mounting groove 201 at the end of the lower stamping seat 2. The limiting block 7 is then pushed to the installation position and the L-shaped buckle 202 is released to limit the limiting block 7. By rotating the sealing plate 302 at the end of the lower mold chamber 3 using the hinge 303 and fixing the latch at the other end to the lower mold chamber 3, a torque is applied to the extrusion bolt 304 to control the multiple molds 305 inside the mold groove 301 to be extruded and contact the limiting block 7. After the mold limiting hole 306 on the lower surface of the outermost mold 305 corresponds to the position of the bottom limiting hole 307 reserved on the lower stamping seat 2, the positioning bolt can be inserted as a whole. This reduces the number of positioning bolts used to fix the mold 305. At the same time, it allows for quick positioning when replacing the mold, and the positioning and installation speed is relatively fast.
