Symmetrically distributed positioning through holes 4 are provided on the positioning plate 3. A connecting plate 5 is provided on one side of the mold body 1. Symmetrically distributed connecting rods 6 are fixedly connected to the left side wall of the connecting plate 5. The ends of the two connecting rods 6 away from the connecting plate 5 are jointly fixedly connected to a mounting plate 7. Symmetrically distributed positioning insertion rods 8 are fixedly connected to the left side wall of the mounting plate 7. Symmetrically distributed springs 9 are fixedly connected to the right side wall of the mounting plate 7. A guiding chute 10 is provided on the right side wall of the mold body 1. A connecting slider 11 is slidably connected inside the guiding chute 10. A rectangular plate 12 is installed on the right side wall of the connecting slider 11. Symmetrically distributed transmission plates 13 are hinged between the rectangular plate 12 and the connecting plate 5. A servo motor 14 is provided above the connecting plate 5. The output end of the servo motor 14 is fixedly connected to a driving shaft 15. A pressing plate 16 is fixedly installed at the end of the driving shaft 15 away from the servo motor 14. When the servo motor 14 is started, the servo motor 14 drives the pressing plate 16 to rotate through the driving shaft 15. An acting force is applied to the rectangular plate 12 through the rotating pressing plate 16, causing the rectangular plate 12 to move downward. The connecting slider 11 slides downward inside the guiding chute 10. Through the two transmission plates 13, the connecting plate 5 is driven to move to the side away from the mold body 1. The two connecting rods 6 and the mounting plate 7 move synchronously with the connecting plate 5. The spring 9 is compressed and deformed under force. When the two positioning insertion rods 8 are respectively disengaged from the two positioning through holes 4, the mold core 2 can be directly taken out from the mold body 1.

[0034] As Figure 1 and Figure 5 shown in the figure, a connecting frame 17 is fixedly connected to the right side wall of the mold body 1. The servo motor 14 is installed on the connecting frame 17. The position of the servo motor 14 is fixed through the connecting frame 17.

[0035] As Figure 2 and Figure 4 shown in the figure, the mounting plate 7 is in contact with the positioning plate 3. The two positioning insertion rods 8 are respectively inserted into the two positioning through holes 4. The positioning plate 3 and the mold core 2 are fixed by the cooperation of the positioning insertion rods 8 and the positioning through holes 4.

[0036] As Figure 5 and Figure 6 shown in the figure, the pressing plate 16 is in contact with the top of the rectangular plate 12.

[0037] As Figure 2 shown in the figure, the end of the spring 9 away from the mounting plate 7 is fixedly connected to the inner side wall of the mold body 1.

[0039] As Figure 6As shown, the rectangular plate 12 is fixedly connected to the connecting slider 11, and the rectangular plate 12 moves synchronously with the connecting slider 11.

[0040] Specifically, when the injection mold facilitating the replacement of the mold core is in use: electrically connect the servo motor 14 to an external control power supply, start the servo motor 14, the servo motor 14 drives the pressing plate 16 to rotate through the drive shaft 15, apply a force to the rectangular plate 12 through the rotating pressing plate 16, so that the rectangular plate 12 moves downward, the connecting slider 11 slides downward in the guiding chute 10, drive the connecting plate 5 to move away from the mold body 1 through the two transmission plates 13, the two connecting rods 6 and the mounting plate 7 move synchronously with the connecting plate 5, the spring 9 is compressed and deformed under force. After the two positioning insertion rods 8 are respectively disengaged from the two positioning through holes 4, directly take out the mold core 2 from the mold body 1, then place a new mold core 2 in the mold body 1, drive the drive shaft 15 and the pressing plate 16 to rotate in the opposite direction through the servo motor 14, drive the mounting plate 7 to move toward the positioning plate 3 through the elastic force of the two springs 9, so that the mounting plate 7 fits with the positioning plate 3, the two positioning insertion rods 8 are respectively inserted into the two positioning through holes 4 to fix the positioning plate 3 and the mold core 2, complete the replacement of the mold core 2. Through the cooperation of the connecting rod 6, the spring 9, the connecting plate 5 and the transmission plate 13, the rectangular plate 12 moves upward and resets, which saves time and effort in the overall operation and improves the replacement efficiency.

[0041] The above embodiments are only used to illustrate the present invention rather than to limit the technical solutions described in the present invention. Although this specification has described the present invention in detail with reference to the above respective embodiments, the present invention is not limited to the above specific implementation manners. Therefore, any modification or equivalent replacement to the present invention; and all technical solutions and their improvements that do not depart from the spirit and scope of the present invention are covered by the scope of the claims of the present invention.
