[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Examples, such as Figure 1 - Figure 3 As shown, this utility model provides a quick mold changing device for automobile wheel hub molds, including a stamping machine 1. A control switch 2 is provided on one outer surface of the stamping machine 1. A quick mold changing assembly 3 is connected to the top surface of the stamping machine 1. The quick mold changing assembly 3 includes a fixing block 301. Slide grooves 302 are provided on both bottom surfaces of the fixing block 301. A mold body 311 is provided on the top surface of the fixing block 301. A throttle 303 is inserted into the front end of the fixing block 301. A first gear 30 is connected to the surface of the throttle 303. 4. A second gear 305 is connected to the surface of the first gear 304. A bidirectional screw 306 is inserted into the inside of the second gear 305. Movable plates 307 are connected to both sides of the bidirectional screw 306. Threaded holes 308 are opened at the bottom of the movable plates 307. Insert blocks 309 are connected to the inner sides of both sets of movable plates 307. Pressure sensors 310 are connected to the front end of each set of insert blocks 309. A slider 312 is connected to the bottom of the mold body 311. An alarm 313 is connected to one side of the stamping machine 1.

[0024] like Figure 2 As shown, the alarm 313 is electrically connected to the pressure sensor 310. The mold body 311 has slots on both sides that match the insert 309. The mold body 311 can be quickly installed by the cooperation of the insert 309 and the slot.

[0025] like Figure 2 and Figure 3 The position and size of the first gear 304 match the position and size of the second gear 305. The first gear 304 and the second gear 305 form a meshing connection, which enables the rotation of the bidirectional screw 306.

[0026] like Figure 4 As shown, the bidirectional screw 306 is connected to the movable plate 307 by a threaded hole 308. The slider 312 is T-shaped and is connected to the slide groove 302 by a sliding connection. The threaded connection allows for easy adjustment of the positions of the two movable plates 307.

[0027] like Figure 1 and Figure 4As shown, a protective component 4 is provided on the surface of the control switch 2. The protective component 4 includes a hinge 401, a protective cover 402 is connected to the surface of the hinge 401, and a magnetic block 403 is connected to the bottom surface of the protective cover 402. The protective component 4 can protect the control switch 2.

[0028] like Figure 4 As shown, a magnet 404 is connected to the front surface of the control switch 2. The magnet 404 and the magnetic block 403 form a magnetic connection, which can fix the control switch 2.

[0029] The overall effect of this embodiment is as follows: when the mold body 311 needs to be replaced, the handle 303 can be rotated in the reverse direction, so that the handle 303 can drive the first gear 304 to rotate. At the same time, the first gear 304 will also mesh with the second gear 305 in the opposite direction, thereby causing the bidirectional screw 306 to rotate in the opposite direction. When the bidirectional screw 306 rotates in the reverse thread, it can simultaneously rotate in the opposite thread with the two sets of moving plates 307 through the threaded hole 308. Thus, through the reverse thread rotation, the two... Simultaneously, the movable plate 307 moves inward, causing the insert block 309 to be pulled out of the slot of the mold body 311. Then, the mold body 311 can be pulled outward, allowing it to slide out of the slide groove 302 via the bottom slider 312, thus completing the disassembly of the mold body 311. When installing a new mold body 311, it can be pushed into the slide groove 302 via the bottom slider 312. Then, the handle 303 can be rotated forward to drive the first gear 30. 4. The forward rotation causes the bidirectional screw 306 to rotate forward, which in turn causes the two sets of moving plates 307 to push the insert block 309 inward and insert it into the slot of the mold body 311 for fixation. At this time, the pressure sensor 310 can be turned on to observe the pressure value during clamping. After the required pressure is reached, the throttle 303 can be stopped. When the insert block 309 becomes loose after long-term use, the pressure sensor 310 will send an electrical signal to the alarm 313, which will sound an alarm to remind the operator to handle the situation. This avoids the problem of the traditional mold body 311 being fixed with bolts, which is very inconvenient when replacing it, and improves the flexibility of mold body 311 replacement. After the control switch 2 is set, the protective cover 402 can be rotated by the hinge 401 to protect the control switch 2. At this time, the magnetic block 403 and the magnet 404 will also be magnetically fixed to prevent accidental contact with the control switch 2 and change of settings, which may cause damage to the processed car wheel hub.

[0030] Working principle: When the mold body 311 needs to be replaced, the handle 303 can be turned to pull out the two sets of inserts 309 from the slots, and then the mold body 311 can be directly removed. The new mold body 311 can be quickly installed by sliding connection, and then the inserts 309 can be inserted into the slots for fixation by turning the handle 303. This avoids the problem of the traditional mold body 311 being fixed with bolts, which is very inconvenient when replacing, and improves the flexibility of mold body 311 replacement. After the control switch 2 has set the pressure and frequency of the stamping machine 1, the surface of the control switch 2 can be protected by the protective cover 402, and the magnetic connection can fix the control switch 2 to prevent accidental contact with the control switch 2 to change the settings and cause damage to the processed car wheel hub.

[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
