[0033] Reference Figure 3 The inner wall of the lower mold 2 is fixedly connected with a shaping mold 12. By fixing the shaping mold 12 on the inner wall of the lower mold 2, a hollow effect can be formed during injection molding.

[0034] Reference Figure 1-Figure 3 One end of the hinged rod 6 is hinged to the outer wall of the pull rod 7, and the other end of the hinged rod 6 is fixedly connected to the outer wall of the slider 8. Through the hinge of the hinged rod 6, when the pull rod 7 is pulled upward or downward, the slider 8 can be vertically moved along the inner wall of the upper mold 1 through the hinge of the hinged rod 6, thereby fixing and releasing the upper mold 1 and the lower mold 2.

[0035] Reference Figure 4 The inner wall of the lower mold 2 is elastically connected with the inclined block 13 through a spring 15. The elastic force of the spring 15 enables the inclined block 13 to always maintain the effect of moving outward without being affected by external force. The outer wall of the inclined block 13 is slidably connected to the inner wall of the lower mold 2. The outer wall of the inclined block 13 is slidably connected to the inner wall of the lower mold 2, so that the inclined block 13 can move laterally along the inner wall of the lower mold 2.

[0038] Reference Figure 3 A positioning block 16 is fixedly connected to the top of the lower mold 2. By providing a fixed support for the positioning block 16 at the top of the lower mold 2, the outer wall of the positioning block 16 is plugged into the inner wall of the upper mold 1. By plugging the outer wall of the positioning block 16 into the inner wall of the upper mold 1, the upper mold 1 will not move laterally when closing with the lower mold 2.

[0039] Working principle: When using the device, first inject the molten plastic raw material into the mold cavity along the injection hole A9 at the top of the upper mold 1. After the shell in the mold is cooled, push the rod body 14 inward to drive the inclined block 13 to move inward, so that it releases the clamping of the pull rod 7, and then push the pull rod 7 upward to drive the slider 8 to move vertically along the inner wall of the upper mold 1 and disengage from the upper mold 1 to release the fixation of the upper mold 1, and then start the motor 4 to drive the threaded rod 5 to rotate and drive the upper mold 1 to move upward, and then the staff takes out the shell.

[0040] When the next shell is to be injection molded, the motor 4 is started first to drive the upper mold 1 to fit with the lower mold 2, and then the slider 8 is inserted into the inner wall of the upper mold 1, and then the pull rod 7 is pressed downward to drive the slider 8 to move downward. When the pull rod 7 moves to the position of the inclined block 13, the pull rod 7 is pressed, and the inclined surface of the inclined block 13 will be squeezed and moved inward, so that the pull rod 7 can continue to move. When the pull rod 7 moves to the specified position, the inclined block 13 will move outward due to the elastic force of the spring 15, and be clamped with the inner wall of the pull rod 7, so that it can fix the pull rod 7. At the same time, the slider 8 will move to the specified position to squeeze the upper mold 1 downward, so as to fix the upper mold 1 and the lower mold 2, and then repeat the above operation to perform injection molding and remove the shell.
