[0028] The effect achieved by the entire embodiment is that the injection mold installation structure consists of a mounting assembly 1, an upper mold 3 and a lower mold 2. When the injection mold needs to be installed before use, first align the bottom of the lower mold 2 with the placement plate 113 (such as Figure 3As shown in the figure, the lower mold 2 is placed on the placement plate 113, and the placement plate 113 moves downward under the action of gravity of the lower mold 2. The top of the protruding rod 114 passes through the hole and is located at the top of the mounting base 11 (the diameter of the top baffle of the protruding rod 114 is larger than the hole diameter). When the protruding rod 114 and the connecting rod 116 move downward with the placement plate 113, the movable plate 110 deflects toward the lower mold 2 until the protruding rod 114 can no longer move downward (blocked by the top baffle). At this time, the pressing block 112 at the top of the movable plate 110 is just stuck in the notch 5, and the lower mold 2 is stably mounted on the mounting base 11.

[0029] The use method and working principle of the device: When the injection mold needs to be installed before use, first place the lower mold 2 on the placement plate 113, and the placement plate 113 moves downward under the gravity of the lower mold 2. When the protruding rod 114 and the connecting rod 116 move downward with the placement plate 113, the movable plate 110 deflects toward the lower mold 2 until the protruding rod 114 can no longer move downward. At this time, the pressing block 112 at the top of the movable plate 110 is just stuck in the notch 5, and the lower mold 2 is stably installed on the installation base 11. Through the above structure, the lower mold 2 can be automatically pressed and installed without the need to use multiple bolts for installation and fixing, and installation and disassembly are more convenient and less time-consuming;

[0030] After the lower mold 2 is installed, the upper mold 3 is slowly moved downward until the limiting hole of the upper mold 3 is sleeved on the fixing column 19, and the stepper motor 111 is turned on. The stepper motor 111 drives the bevel gear plate 12 to rotate, which in turn drives the bevel gear rod 13 and the threaded rod 14 to rotate, and the rotation directions of the two threaded rods 14 are opposite, so that the two adjustment plates 15 can move in the opposite direction. Figure 2 As shown, when the upper mold 3 needs to be installed, the bevel gear disk 12 is driven by the stepper motor 111 to rotate clockwise, so that the two adjustment plates 15 move toward each other, and the insert block 17 is inserted into the slot 4, so as to quickly fix the upper mold 3. When the upper mold 3 needs to be removed, the bevel gear disk 12 is driven by the stepper motor 111 to rotate counterclockwise, so that the two adjustment plates 15 move back to back, and the insert block 17 is moved out of the slot 4, thereby realizing the rapid installation and fixation between the upper mold 3 and the lower mold 2. The upper mold 3 and the lower mold 2 can be quickly installed through the installation component 1, and the installation effect is more stable and not easy to loosen, thereby improving the use effect of the injection mold.
