[0002] In related technologies, such as Figures 1 to 3 As shown, a stamping die generally includes a stripper plate, a stop plate, and a slide block. The stripper plate and the stop plate are connected, forming a cavity with an opening on one side. The slide block is installed in the cavity, allowing it to slide back and forth to achieve stamping. However, since the working part is connected to the end of the slide block facing the cavity opening, disassembling the slide block requires loosening multiple screws, fixing pins, and other fasteners on the stop plate one by one. The slide block is then disassembled from the side of the stripper plate facing the stop plate. This operation is cumbersome and time-consuming. Especially when the die malfunctions during production, it is difficult to disassemble and reassemble on the stamping press. The die must be disassembled before the slide block can be removed, which is time-consuming, labor-intensive, and reduces production efficiency. Utility Model Content

[0032] The following is combined Figures 4 to 6 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, in one aspect, a quick-release structure for a commutator die slider is provided, comprising: a die body 1, the side wall of which is provided with a cavity 3 along a first direction; a slider insert 2, which is slidably disposed in the cavity 3; and an auxiliary block 4, which is detachably embedded in the end of the cavity 3; the length of the auxiliary block 4 along the first direction is greater than or equal to the length of the slider insert 2 along the first direction.

[0034] In this embodiment, a sliding insert is slidably provided in the cavity 3 of the mold body 1, allowing the sliding insert to slide back and forth in the cavity 3. At the same time, an auxiliary block 4 is detachably embedded at the end of the cavity 3. When it is necessary to remove the slider insert 2, only the auxiliary block 4 needs to be removed, leaving a certain clearance space at the end of the cavity 3. Since the length of the auxiliary block 4 is greater than or equal to the length of the slider insert 2, the slider insert 2 can slide into the clearance space and be removed from the clearance space without disassembling the entire mold body 1, saving time and effort. When it is necessary to install the slider insert 2, the slider insert 2 can be slid from the clearance space into the cavity 3, and the auxiliary block 4 is embedded again at the end of the cavity 3 for limiting, preventing the slider insert 2 from falling out of the cavity 3. The disassembly and assembly are convenient and quick, reducing maintenance costs and time, and improving production efficiency.

[0035] In one embodiment, such as Figure 4 and Figure 6 As shown, the auxiliary block 4 is connected to the mold body 1 by the first screw 5.

[0036] In this embodiment, the auxiliary block 4 is connected to the mold body 1 by the first screw 5, which facilitates installation and disassembly.

[0037] Specifically, the first screw 5 passes through the auxiliary block 4 from one side of the opening end of the cavity 3 and is threaded to the bottom of the cavity 3, which facilitates installation and disassembly.

[0038] Specifically, the first screw 5 can be an M5 fixing screw, and the choice can be made according to actual needs.

[0039] In one embodiment, such as Figure 4 and Figure 5 As shown, the quick-release structure of the commutator die slider also includes a second screw 6, and each slider insert 2 is provided with a second screw 6; the second screw 6 is slidably passed through the die body 1 and the auxiliary block 4 in sequence along the first direction, and the second screw 6 is threadedly connected to the slider insert 2; a spring 7 is sleeved between the head of the second screw 6 and the die body 1.

[0040] It should be noted that the head of the second screw 6 extends to the outside of the mold body 1, and the shank of the second screw 6 extends into the cavity 3.

[0041] In this embodiment, a second screw 6 is provided. The second screw 6 passes through the mold body 1 from the side in the first direction and extends into the cavity 3. The second screw 6 is slidably connected to the mold body 1 and the auxiliary block 4 in the first direction and is threadedly connected to the sliding insert so that the sliding insert can provide force through the spring 7 when it reciprocates.

[0042] In one embodiment, such as Figure 4 and Figure 5 As shown, a mounting groove is provided on the end face of the mold body 1 corresponding to the spring 7; one end of the spring 7 abuts against the head of the second screw 6, and the other end is embedded in the mounting groove and abuts against the bottom of the mounting groove.

[0043] In this embodiment, by providing a mounting slot, it is easier to install the spring 7, reducing the space occupied by the spring 7 and thus reducing the overall size.

[0044] In one embodiment, the second screw 6 is a height-equal screw.

[0045] In this embodiment, the second screw 6 is an equal-height screw to facilitate sliding cooperation with the mold body 1 and the auxiliary block 4.

[0046] In one embodiment, such as Figures 4 to 6 As shown, there are two slider inserts 2, which are symmetrically arranged in the cavity 3. Two auxiliary blocks 4 are respectively provided at both ends of the cavity 3.

[0047] In this embodiment, two slider inserts 2 are symmetrically arranged in the cavity 3 along the first direction. At the same time, two auxiliary blocks 4 are respectively provided at both ends of the cavity 3 so that when removing the slider inserts 2, the slider inserts 2 can be removed by removing the corresponding auxiliary blocks 4, which is convenient and quick.

[0048] In one embodiment, such as Figure 5 and Figure 6 As shown, the mold body 1 includes a stop plate 101 and a stripper plate 102; the stripper plate 102 is provided with a groove along the first direction; the stop plate 101 is stacked on the stripper plate 102 and forms a cavity 3 with the groove; the stop plate 101 and the stripper plate 102 are detachably connected.

[0049] In this embodiment, the mold body 1 is formed by stacking a stop plate 101 and a stripper plate 102, which facilitates installation and disassembly for maintenance. When the stop plate 101 and the stripper plate 102 are stacked, the slide groove and the stop plate 101 enclose the cavity 3, that is, the stop plate 101 constitutes the bottom of the cavity 3, which facilitates the sliding operation of the slider insert 2.

[0050] Specifically, the second screw 6 is inserted into the stripper plate 102.

[0051] Specifically, the first screw 5 passes through the auxiliary block 4 and is threaded onto the stop plate 101.

[0052] In one embodiment, such as Figure 4 and Figure 6 As shown, the stop plate 101 is connected to the stripper plate 102 by the third screw 8.

[0053] In this embodiment, the stop plate 101 is connected to the stripper plate 102 by the third screw 8, which facilitates installation and disassembly.

[0054] Specifically, the third screw 8 can be an M6 fixing screw, and the choice can be made according to actual needs.

[0055] In one embodiment, such as Figure 4 and Figure 6 As shown, the stop plate 101 is positioned and connected to the stripper plate 102 by the positioning pin 9.

[0056] In this embodiment, the stop plate 101 is positioned and connected to the stripper plate 102 by the positioning pin 9 to ensure connection accuracy.

[0057] Specifically, the auxiliary block 4 is provided with a first through hole for the first screw 5 to pass through and a second through hole for the second screw 6 to pass through. The first through hole and the second through hole are staggered to avoid interference between them during connection.

[0058] Specifically, the auxiliary block 4 has a protrusion on the side wall in the width direction of the cavity 3, and the side wall of the cavity 3 is provided with a groove corresponding to the protrusion to improve the stability of the auxiliary block 4 when it is fixed.

[0059] The specific disassembly and assembly principle of the quick-release structure for the commutator die slider provided in this embodiment is as follows: When it is necessary to disassemble the slider insert 2, firstly, remove the second screw 6 and pull it out, then pull out the spring 7, then loosen the first screw 5 and remove the auxiliary block 4 from the opening end of the cavity 3, so that a certain clearance space is left at the end of the cavity 3, and then slide the slider insert 2 into the cavity 3 to the clearance space. There is no need to disassemble the stop plate 101 and the stripper plate 102, saving time and effort. When it is necessary to install the slider insert 2, the slider insert 2 can be slid from the clearance space into the cavity 3 and slid to the middle position. Then, the auxiliary block 4 is embedded in the end of the cavity 3 again and fixed by the first screw 5 to secure the slider insert 2. This device features a limit switch to prevent the slider insert 2 from dislodging from the cavity 3. It boasts a simple structure, low manufacturing cost, and convenient and quick assembly and disassembly. It can be disassembled and assembled on the press without removing the mold, reducing maintenance or replacement time, minimizing downtime, lowering maintenance costs and time, and improving production efficiency. It also avoids the need for refeeding and resetting after mold disassembly, saving product materials and thus reducing costs. It is applicable to stamping dies for all K-type commutator products, offering a wide range of applications. This solution addresses the problem of existing stamping dies requiring the loosening of multiple screws, fixing pins, and other fasteners on the stop plate 101 one by one when disassembling the slider. This cumbersome and time-consuming operation is especially problematic when mold malfunctions during production, making disassembly on the press difficult and necessitating mold disassembly to remove the slider, which is time-consuming, labor-intensive, and reduces production efficiency.

[0060] According to an embodiment of the present invention, in another aspect, a stamping die is provided, including a commutator die slider quick-release structure as described in any of the first aspects.

[0061] In this embodiment, the stamping die adopts a quick-release structure for the commutator die slider of any embodiment of the first aspect. The specific structure of the quick-release structure for the commutator die slider is the same as that of the quick-release structure for the commutator die slider of any embodiment of the first aspect. This makes the stamping die with the quick-release structure for the commutator die slider have at least the same technical effect as the above-mentioned quick-release structure for the commutator die slider. The specific principle is the same as that of any embodiment of the first aspect, and will not be described in detail here. This solves the problem that when disassembling the slider of the existing stamping die, it is necessary to loosen the more than 101 screws, fixing pins and other fasteners of the stop plate one by one. The operation is cumbersome and time-consuming. In particular, if the die is abnormal during the production process, it is difficult to disassemble and assemble on the press. The die must be disassembled before the slider can be disassembled, which is time-consuming, labor-intensive and reduces production efficiency.

[0062] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
