[0038] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] A rapid mold change rotation system, characterized in that: Figure 1 As shown, it comprises a base 1, a rotating disk 2 is provided below the base 1, a partition 3 is provided above the base 1, and two sides of the base 1 extend horizontally outward to form a workbench 4. Figures 2~4 As shown, a pair of raised portions 5 are symmetrically provided on both sides of the workbench 4, a positioning support pin 6 is penetrated through the center of the raised portion 5, the upper part of the positioning support pin 6 is annularly protruding to form a fastener 7, a limiting pad 8 is provided on the workbench 4, a moving cylinder 14 is provided on the rear side of the middle part of the limiting pad 8, the moving cylinder 14 drives the limiting pad 8 to slide back and forth, the two ends of the limiting pad 8 are respectively arranged on the upper end surfaces of the two raised portions 5, the two ends of the limiting pad 8 are respectively bent to the rear side to form a clamping portion 9, the junction of the clamping portion 9 and the middle part of the limiting pad 8 forms a rounded corner, which is safe during manual operation, such as Figure 5 As shown, the front end of the engaging portion 9 is recessed toward the rear side to form an arc groove 10 , and the arc groove 10 is arranged in the vertical direction. The size of the arc groove 10 matches the lower part of the positioning support pin 6 .

[0040] There are four workbenches 4, which are arranged parallel to each other at the front and rear sides of both sides of the base 1. A heightening mechanism 11 is provided on the upper end surface of the workbench 4, and the heightening mechanism 11 includes a cross bar 13 and two vertical bars 12. The cross bar 13 is arranged parallel to the front side of the workbench 4, and the cross bar 13 is suspended in front of the workbench 4. One end of the cross bar 13 is bent inwardly and pressed against the front side of the protrusion 5, so as to limit the range of movement of the heightening mechanism 11 toward the rear side of the workbench 4. The vertical bar 12 is arranged perpendicular to the cross bar 13, and the rear part of the vertical bar 12 is engaged between the lower end surface of the limiting pad 8 and the upper end surface of the workbench 4.

[0041] The interior of the workbench 4 is hollow, and a plurality of windows 15 are provided at the rear opening of the workbench 4 , through which the height of the positioning support pins 6 can be adjusted using a clamp.

[0042] In the specific implementation, the clamp 16 is set on one side of the partition 3, and casters or a quick-change trolley are provided under the clamp to facilitate manual switching without auxiliary lifting tools, such as Figure 8 As shown, the clamp 16 relies on its own weight and the four positioning pin holes it has to cooperate with the positioning support pins 6 of the workbench 4 for positioning and support. The moving cylinder 14 and the raising mechanism 11 cooperate with the bottom surface of the clamp to assist in positioning the clamp on the two workbenches 4 on the same side.

[0043] In the initial state, if Figure 5 As shown, the bottom surface of the fastener 7 is set close to the upper end surface of the workbench 4, and the limiting pad 8 is at a distance from the outer side of the fastener 7. Then the positioning support pin 6 is lifted up, as shown in FIG. Figure 6 As shown, the limiting pad 8 is gradually pushed toward the rear side of the workbench 4 until the arc grooves 10 at both ends of the limiting pad 8 cooperate with the cylindrical body at the bottom of the positioning support pin 6, as shown in FIG. Figure 7 As shown, the positioning support pin 6 is lowered so that the lower end surface of the fastener 7 is tightly matched with the upper end surface of the arc groove 10. At this time, the limit pad 8 is relatively fixed to the workbench 4, and the movable cylinder 14 remains stationary. The clamp cooperating with the movable cylinder 14 completes the positioning, and the rotating disk 2 rotates to drive the workbench 4 to adjust to any desired angle. The work is simple and efficient, and the clamp can be replaced when the positioning support pin 6 is lifted up again.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
