Description

Technical Field

[0001] This utility model belongs to the field of precision mold rapid mold changing technology, and in particular relates to a precision mold rapid mold changing device. Background Technology

[0002] Precision molds are specialized forming tools used to produce parts with extremely high requirements for dimensional accuracy, surface quality, and structural complexity.

[0003] When producing parts of different shapes, it is usually necessary to change precision molds. However, when traditional precision molds cannot be changed using hoisting equipment, workers usually have to lift the precision molds and install them on stamping equipment or remove them from the equipment. Since the molds themselves are heavy, manually lifting the molds not only greatly increases the labor force, but also easily leads to accidents such as falling. Falling can also cause damage to the molds or even injury to the workers. Therefore, we have proposed a precision mold quick mold changing device. Utility Model Content

[0037] One specific application of this embodiment is:

[0038] In use, the front motor 223 is started, driving the front lead screw 222 to rotate counterclockwise, causing the lifting platform 224 to move downwards. During this movement, the lifting platform 224 slides on the limit rod 225, making its movement more stable. The front support plate 233 then moves downwards along with the lifting platform 224, facilitating the placement of the mold to be replaced on the front support plate 233. After placement, the push handle 11 is used to move the moving vehicle 1 to the equipment where the mold needs to be replaced, aligning the rear support plate 233 with the mold on the equipment. Then, the rear motor 223 is started, driving the rear lead screw 222 to rotate, causing the rear support plate 233 to move upwards or downwards to a suitable height. When mold removal is required, the support plate 223 is moved downwards. 33 Move to the bottom of the mold. When the lower mold needs to be disassembled, move the lifting plate 233 to the installation position of the lower mold. When disassembling the lower mold, turn the rear threaded knob 236 counterclockwise to release the fixation of the rear lifting plate 233. Then push the lifting plate 233 to the position of the lower mold. The slider 234 slides on the crossbar 231, and the limit block 235 slides in the slide groove 232. After the movement is completed, turn the threaded knob 236 clockwise to fix the slider 234. The position of the lifting plate 233 is fixed. Then disassemble the lower mold and place it on the lifting plate 233. When the upper mold needs to be disassembled, move the lifting plate 233 to the bottom of the upper mold and disassemble the upper mold. The lifting plate 233 supports and places the mold, which can quickly complete the disassembly.

[0039] After disassembly, the lifting plate 233 containing the mold is pushed and retracted towards the fixed plate 221. Then, the worker pushes the fixed plate 221, causing the rotating plate 211 to rotate. The bottom of the rotating plate 211 rotates on the moving vehicle 1 via the limiting shaft 212. The rotating plate 211 also drives the annular slide rail 213 to rotate on the annular support rail 214, making the rotation more stable. Furthermore, because the bottom of the positioning rod 243 and the positioning groove 246 are both spherical, the positioning rod 243 can smoothly disengage from the positioning groove 246 and move upwards. By pressing the spring 245 with the convex ring 244, and by rotating the fixed plate 221 180 degrees, the positioning rod 243 moves into another positioning groove 246 and springs into the positioning groove 246 under the elastic action of the spring 245, thus positioning the rotation position of the rotating disk 211. The new mold can then be adjusted by lifting and adjusting the position of the lifting plate 233 to send the mold to the appropriate position on the equipment, thereby installing the upper or lower mold and completing the replacement work. Finally, the mobile vehicle 1 is moved away, and the removed mold is put into the warehouse for storage.
