The left and right ends of the inner side of the mold 14 are slidably connected to the left and right ends of the splint 9, which is convenient for disassembly and installation of the mold 14.

[0035] Working principle: when it is necessary to clamp the parts, the electric push rod 3 is started to drive the slide plate 4 to move to the left and slide inside the support plate 6. Since the rack 5 is fixedly connected to the upper end of the slide plate 4, the rack 5 is transmitted to the gear 11, and the gear 11 is transmitted to the bidirectional threaded rod 10. The bidirectional threaded rod 10 is transmitted to the two clamping plates 9 through the thread groove 15, driving the two clamping plates 9 to move toward each other along the groove 17 inside the support plate 6 to complete the clamping of the parts. When it is necessary to loosen, the electric push rod 3 is controlled to make the slide plate 4 move to the right to complete the loosening of the processed parts. When different types of parts need to be processed, the threaded pin 13 is twisted to make it slide out from the thread groove 2 16 inside the top of the clamping plate 9. After the threaded pin 13 is removed, the fixer 18 is retracted to the groove 2 17 inside the left and right ends of the clamping plate 9 under the joint action of the spring 21 and the connecting plate 20, thereby releasing the fixation of the mold 14 and taking out the mold 14 for replacement. After the replacement is completed, it can be fixed again by following the reverse steps.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
