[0031] like Figure 1 As shown, this utility model embodiment provides a pressing mold with a quick-change locking mechanism 120, including: an upper mold assembly and a lower mold assembly used in conjunction; the upper mold assembly includes an upper mold base 100 and a first pressing head 110, and a quick-change locking mechanism 120 is provided between the upper mold base 100 and the first pressing head 110. The quick-change locking mechanism 120 includes a locking groove 140 provided in the upper mold base 100 and a locking block 130 provided on the first pressing head 110; the locking block 130 is matched and connected to the locking groove 140; the lower mold assembly includes a lower mold base 200 and a second pressing head 210, the lower mold base 200 is fixedly connected to the second pressing head 210, and a pressing cavity 220 is provided in the second pressing head 210. The first pressing head 110 cooperates with the pressing cavity 220 to realize product pressing and forming.

[0032] When the first pressure head 110 of the pressing die needs to be replaced, the quick-change locking mechanism 120 is used to separate the locking groove 140 on the upper die base 100 and the locking block 130 on the first pressure head 110, thus removing the first pressure head 110 from the upper die base 100. Then, the locking block 130 on the new first pressure head 110 is fixed to the locking groove 140 on the upper die base 100, connecting the upper die base 100 and the first pressure head 110. This allows for the assembly and replacement of the upper die assembly, resulting in high efficiency, significantly saving time and manpower, and improving production efficiency. Furthermore, because the locking block 130 and the locking groove 140 are matched and connected, rapid positioning in the width direction is possible, improving the alignment accuracy of the pressing die, reducing problems such as offset and deformation of the pressing die during the pressing process, and improving the processing quality of ferrite.

[0033] When the pressing mold is working, the first pressing head 110 is embedded in the pressing cavity 220, and together with the second pressing head 210, they form a pressing space, in which the pressing of ferrite is completed.

[0034] It should be noted that, in some embodiments, the quick-change locking mechanism 120 includes a locking block 130 disposed on the upper mold base 100 and a locking groove 140 disposed on the first pressure head 110; the locking block 130 and the locking groove 140 are matched and connected.

[0035] According to some embodiments of this application, the cross-section of the locking block 130 along the width direction is an inverted trapezoid with a top width greater than the bottom width, and the cross-section of the locking groove 140 along the width direction is also an inverted trapezoid with a top width greater than the bottom width. By matching and connecting the inverted trapezoidal locking block 130 and the inverted trapezoidal locking groove 140, the locking effect of the quick-change locking mechanism 120 can be improved, and the separation of the first pressure head 110 from the upper mold base 100 due to inertia during the up and down stamping when the product pressing and molding is completed can be further avoided.

[0036] Furthermore, the lengths of the locking block 130 and the locking groove 140 are equal, so that the locking block 130 can be separated from or fixed by external force.

[0037] Furthermore, grooves 150 are respectively provided on both sides of the first pressure head 110. The grooves 150 extend downward along the height direction of the first pressure head 110 and are used for the robotic arm to grip the first pressure head 110. The robotic arm can easily connect to the grooves 150 and then connect to the first pressure head 110. Through the automated movement of the robotic arm, the automatic replacement of the first pressure head 110 can be realized.

[0038] According to some embodiments of this application, such as Figure 2As shown, the upper mold base 100 has a first screw hole 160 inside, which is a through hole structure. The end of the first pressure head 110 connected to the upper mold base 100 has a second screw hole 170, which is a blind hole structure. Multiple first screw holes 160 and second screw holes 170 can be provided as needed. The first screw holes 160 and second screw holes 170 are matched with each other for connecting the locking screws. The upper mold base 100 and the first pressure head 110 are fixedly connected by the locking screws, further improving the locking effect of the upper mold base 100 and the first pressure head 110.

[0039] Furthermore, such as Figure 3 As shown, the first screw hole 160 is provided with a receiving annular groove 180 at the end away from the quick-change locking mechanism 120 to receive the screw head of the locking screw, so as to prevent the screw head of the locking screw from protruding from the top surface of the pressing mold and affecting the support stability of the pressing mold.

[0040] According to some embodiments of this application, such as Figure 2 and Figure 4 As shown, a positioning hole 230 is provided inside the second pressure head 210, and a positioning block 240 is provided in the lower die base 200. The bottom of the pressing cavity 220 is connected to the positioning hole 230, and the positioning block 240 passes through the positioning hole 230 and is interference-fitted with the positioning hole 230. Through the cooperation of the positioning hole 230 and the positioning block 240, the second pressure head 210 can be quickly positioned and fixedly connected to the lower die base 200, and the positioning is more accurate, avoiding the impact of operation errors on the processing quality of ferrite.

[0041] Furthermore, the lower die assembly also includes a third pressure head 250. The second pressure head 210 has a pressing hole 260, and the bottom of the pressing cavity 220 is connected to the pressing hole 260. The third pressure head 250 passes through the pressing hole 260 and is interference-fitted with it. Specifically, the third pressure head 250 can be configured with various heights. When the height of the ferrite to be processed changes, only the third pressure head 250 of the specified height needs to be replaced, greatly improving the applicability of the pressing die.

[0042] This application also provides a pressing device that utilizes a pressing die with a quick-change locking mechanism. The pressing die with the quick-change locking mechanism is disposed at the pressing end of the pressing device to achieve ferrite pressing. The quick-change locking mechanism 120 improves the efficiency of die changing and also enhances the die alignment accuracy, thereby improving the quality and efficiency of ferrite processing by the pressing device.

[0043] According to some embodiments of this application, the lower mold base 200 of the lower mold assembly is also provided with a third screw hole 270. Multiple third screw holes 270 can be provided as needed. The third screw holes 270, together with screws, are used to fix the lower mold base 200 to the drive assembly of the pressing device for pressing ferrite.
