[0028] 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.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a core changing device, including a fixed base 1, a mounting groove 2, a core body 3 and a mounting mechanism 4;

[0030] Each of the two fixed seats 1 has an installation groove 2 on one of its adjacent sides, and the mold core body 3 is slidably installed inside each of the two installation grooves 2.

[0031] Both fixed seats 1 are equipped with mounting mechanisms 4 for quick loading and unloading of the mold core;

[0032] Specifically, the installation mechanism 4 enables quick replacement of the mold core body 3, allowing the stamping die to adapt more flexibly to the production needs of different products. This reduces the need for large-scale production and inventory due to long mold change times. Quick mold core replacement allows the die to be used more frequently for the production of different products, improving the utilization and turnover rate of the die.

[0033] A limiting seat 5 is fixedly installed on the surface of the mold core body 3. Two slots 6 are opened at one end of the limiting seat 5, and the surfaces of the two slots 6 are integrally machined with a slope. The mounting mechanism 4 is used in conjunction with the two slots 6.

[0034] In this embodiment, as Figure 1 As shown, when a core needs to be replaced, the two limiting posts 42 are pressed together and brought close together. The limiting posts 42 slide within the limiting frame 43, causing the support spring 401 to deform, thus disengaging the limiting posts 42 from the slot 6 and fixing them in place. The movable mold core body 3 can then slide within the mounting groove 2 and be removed. Similarly, the mold core body 3 can be fixed by simply placing it into the mounting groove 2 and sliding it in, engaging the slot 6 in the limiting seat 5 on the back of the mold core body 3 with the limiting post 42. The sloped surface of the slot 6 contacts the limiting post 42 and guides its movement. Under the action of the support spring 401, the limiting post 42 is engaged within the slot 6. The two limiting posts 42 have round holes, through which a metal wire can be passed and twisted together to prevent the two limiting posts 42 from sliding.

[0035] The mounting mechanism 4 includes a mounting frame 41 fixedly mounted on one side of the fixed base 1. The mounting frame 41 has two limiting posts 42 inside. Two limiting frames 43 are slidably mounted on the surface of each of the two limiting posts 42. The surfaces of the four limiting frames 43 are fixedly mounted on the inner wall of the mounting frame 41. Anti-detachment rings 44 are provided at the top and bottom of each of the four limiting frames 43. The anti-detachment rings 44 are fixedly mounted on the surface of the limiting posts 42. The mounting frame 41 has an elastic element 40 inside for pushing the limiting posts 42 to move. The surface of the limiting posts 42 is engaged with the inside of the slot 6.

[0036] It should be noted that, as Figure 3 As shown, when a core needs to be replaced, the two limiting posts 42 are pressed together and brought close together. The limiting posts 42 slide within the limiting frame 43, causing the support spring 401 to deform. This disengages the limiting posts 42 from the slot 6 and fixes them in place. The movable mold core body 3 then slides within the mounting slot 2, allowing the mold core body 3 to be removed.

[0037] The elastic element 40 includes a support spring 401 that is snapped onto one side of the limiting post 42. One end of the support spring 401 is snapped onto the inner wall of the mounting frame. A slide rod 402 is movably sleeved inside the support spring 401. One end of the slide rod 402 is fixedly installed on the surface of the limiting post 42, and the surface of the slide rod 402 is movably sleeved with the inside of the mounting bracket 41.

[0038] Furthermore, such as Figure 3 As shown, under the action of the support spring 401, the limiting post 42 is engaged in the slot 6, and the two limiting posts 42 have round holes, through which a metal wire can pass and be twisted into one to prevent the two limiting posts 42 from sliding.

[0039] Guide strips 15 are integrally machined on both sides of the mold core body 3, and guide grooves 7 that are adapted to the guide strips 15 are opened on both sides of the mounting groove 2.

[0040] Among them, such as Figure 2 As shown, the guide strips 15 on both sides of the mold core body 3 slide in the two guide grooves 7 respectively, providing guidance for the movement of the mold core body 3 and having an anti-detachment effect.

[0041] A stamping die includes a core changing device, and also includes a base plate 8, a top plate 10, a floating plate 11, and a sliding mechanism 9;

[0042] A top plate 10 is provided on the top of the base plate 8, a floating plate 11 is provided between the base plate 8 and the top plate 10, and a sliding mechanism 9 is provided between the base plate 8 and the top plate 10 for the floating plate 11 to slide and reduce friction.

[0043] Specifically, the sliding mechanism 9 makes the floating plate 11 slide more smoothly, and the lubrication mechanism can effectively reduce the friction between the column 91 and the guide seat 92, thereby reducing wear. This not only maintains the accuracy of the column 91 and the guide seat 92, but also extends the overall service life of the mold.

[0044] The sliding mechanism 9 includes four columns 91 fixedly installed on the top of the base plate 8, a top plate 10 installed on the surface of the four columns 91, guide seats 92 slidably installed on the surface of each of the four columns 91, each of the four guide seats 92 being embedded inside the floating plate 11, ball bearings 93 being installed on both sides of the inner wall of the guide seats 92, and grooves 94 for the ball bearings 93 to slide on both sides of each column 91, and a liquid storage component 90 being provided inside the column 91.

[0045] It is worth noting that, such as Figure 1 As shown, cylinder 14 drives floating plate 11 to move. Four guide seats 92 on the surface of floating plate 11 slide on the surface of four columns 91 respectively. The ball bearings 93 in the guide seats 92 slide in the groove 94, which reduces the friction of floating plate 11. When the ball bearings 93 hit the extrusion plate 902, the two extrusion plates 902 move closer to each other and squeeze the elastic cotton 12. The lubricating oil in the elastic cotton 12 flows out through the flow hole 903 on the surface of the extrusion plate 902. The lubricating oil adheres to the ball bearings 93 and the groove 94, improving the lubrication effect and realizing automatic oil discharge. The lubricating oil can be replenished in the storage tank 901.

[0046] The liquid storage component 90 includes a storage tank 901 opened in the column 91, and both sides of the storage tank 901 are connected to extrusion plates 902. Both extrusion plates 902 have flow holes 903 inside.

[0047] Furthermore, such as Figure 4 As shown, by adding lubricating fluid to the storage tank 901, when the ball 93 strikes the extrusion plate 902, the two extrusion plates 902 approach each other and squeeze the elastic cotton 12, causing the lubricating fluid in the elastic cotton 12 to flow out through the flow hole 903 on the surface of the extrusion plate 902. The lubricating fluid adheres to the ball 93 and the groove 94, improving the lubrication effect.

[0048] An elastic cotton 12 is provided between the two extrusion plates 902, and the top and bottom of the extrusion plates 902 are both set as inclined surfaces;

[0049] Among them, such as Figure 5 As shown, the top and bottom of the extrusion plate 902 are both set as inclined surfaces, which is beneficial for the impact of the ball bearing 93 on the extrusion plate 902, and the elastic shell restores the two extrusion plates 902.

[0050] The top of each of the four columns 91 is threaded with a sealing cap 13, and the top plate 10 is embedded with a cylinder 14. The lower end of the cylinder 14 is fixedly installed on the top of the floating plate 11.

[0051] Furthermore, such as Figure 4 As shown, the sealing cap 13 is located at the top of the column 91 and serves to seal the top of the column 91.

[0052] When the device needs to replace the core, the two limiting posts 42 are pressed together and brought close. The limiting posts 42 slide within the limiting frame 43, causing the support spring 401 to deform, thus disengaging the limiting posts 42 from the slot 6 and fixing them in place. The movable mold core body 3 can then slide within the mounting groove 2 and be removed. Similarly, the mold core body 3 can be fixed by simply placing it into the mounting groove 2 and sliding it, engaging the slot 6 in the limiting seat 5 on the back of the mold core body 3 with the limiting post 42. The sloped surface of the slot 6 contacts the limiting post 42 and guides the limiting post 42 to move. Under the action of the support spring 401, the limiting post 42 is engaged within the slot 6. The two limiting posts 42 have round holes, through which a metal wire can be passed and twisted together to prevent the two limiting posts 42 from sliding.

[0053] The cylinder 14 drives the floating plate 11 to move. The four guide seats 92 on the surface of the floating plate 11 slide on the surface of the four pillars 91 respectively. The ball bearings 93 in the guide seats 92 slide in the groove 94, which reduces the friction of the floating plate 11. When the ball bearings 93 hit the extrusion plate 902, the two extrusion plates 902 move closer to each other and squeeze the elastic cotton 12. The lubricating oil in the elastic cotton 12 flows out through the flow hole 903 on the surface of the extrusion plate 902. The lubricating oil adheres to the ball bearings 93 and the groove 94, which improves the lubrication effect and realizes automatic oil discharge. The lubricating oil can be replenished in the storage tank 901.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
