[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0026] The present invention provides a mobile phone protective cover liquid injection molding automation equipment, such as Figure 1-4 As shown, it comprises a fixed mold 1 and a movable mold 2, wherein a fixed mold core 3 and a movable mold core 4 are respectively arranged inside the fixed mold 1 and the movable mold 2, a molding block 5 is arranged inside the molding cavity of the fixed mold core 3, a moving block 6 is arranged at the middle of the rear side of the molding block 5, and the end of the moving block 6 is fixedly connected to the external driving mechanism;

[0027] A placement slot 7 is provided at the rear side of the forming block 5 . Pushing blocks 8 are provided around the placement slot 7 . A deflection mechanism is provided between the forming block 5 and the four pushing blocks 8 .

[0028] When the mobile phone cover is demolded, the movable mold 2 drives the movable mold core 4 to leave, and the external driving mechanism drives the forming block 5 to move through the moving block 6, and the mobile phone cover leaves the forming groove position of the fixed mold core 3. After a certain distance, the linkage mechanism works to extend the four pushing blocks 8 from the four sides of the forming block 5. The four pushing blocks 8 push the arc-shaped edges of the mobile phone cover to deform. Under the action of the linkage mechanism, the four pushing blocks 8 deflect at the same time, and the arc-shaped edges of the propped-up mobile phone cover are deformed and reset along the surface of the pushing blocks 8, and the mobile phone cover automatically detaches from the surface of the forming block 5.

[0029] like Figure 2-4 As shown, the deflection mechanism includes a deflection block 9, one end of which is fixedly connected to the push block 8, and both sides of the deflection block 9 are provided with limit blocks 10. The surface of the placement slot 7 is provided with a limit slot 11, and the limit block 10 is movably inserted in the limit slot 11. The limit slot 11 is in a zigzag shape, and a plurality of teeth are provided on the top of the limit slot 11. The bottom of the limit block 10 is provided with a tooth groove matching the limit slot 11. The other end of the deflection block 9 is provided with an extrusion block 12, and both ends of the extrusion block 12 are provided with auxiliary blocks 13. A connecting block 14 is sleeved on the surface of the auxiliary block 13, and one end of the connecting block 14 is sleeved on the surface of the limit block 10. The end of the extrusion shift block 12 is set in a cone shape, and the cone surfaces of the four extrusion shift blocks 12 correspond to each other, and the four extrusion shift blocks 12 form a square. The lengths of two relative extrusion shift blocks 12 are the same, and the lengths of two adjacent extrusion shift blocks 12 are the same only at the cone position. The rotation center of the push block 8 and the deflection block 9 is the top center position of the limit slot 11, and the maximum deflection angle of the push block 8 and the deflection block 9 is 5 degrees.

[0030] When the moving block 6 moves, its internal components squeeze the four extrusion moving blocks 12 outward in their respective directions. The extrusion moving block 12 moves and moves the limit block 10 through the connecting block 14 sleeved on the surface of the auxiliary block 13, and the deflection block 9 can then drive the pushing block 8 to move. During the movement of the deflection block 9, because the limit groove 11 is in a zigzag shape, the limit block 10 moves up and drives the deflection block 9 and the pushing block 8 to move up. When the limit block 10 moves to a certain distance from the limit groove 11, the teeth act on the tooth groove to cause the limit block 10 to deflect, and the deflection block 9 then drives the pushing block 8 to rotate to the maximum extent.

[0031] The present invention is provided with a deflection mechanism, which can move the push block 8 to support the arc-shaped edge of the mobile phone protective cover. The deflection mechanism drives the push block 8 to deflect slightly, so that the arc-shaped edge of the mobile phone protective cover slides along the push block 8 and can automatically detach from the surface of the forming block 5. There is no need for manual demoulding. Mechanical movement is used instead of manual operation, which improves work efficiency and reduces production costs, effectively improving production efficiency.

[0032] like Figure 2-3 As shown, a working groove 15 is provided inside the moving block 6, and a steering gear 16 is rotatably inserted inside the working groove 15. An L-shaped rack 17 and a spur rack 18 are respectively meshed on both sides of the steering gear 16. A spring 19 is fixedly connected to one side of the L-shaped rack 17, and one end of the spring 19 is fixedly connected to the inner wall of the working groove 15. One end of the L-shaped rack 17 passes through the working groove 15 and extends to the outside of the moving block 6. An extrusion push block 20 is fixedly connected to the end of the spur rack 18. One end of the extrusion push block 20 is hemispherically arranged, and the arc surface of the extrusion push block 20 fits with the top frustum surface of the extrusion moving block 12.

[0033] When the moving block 6 moves to a certain distance, the L-shaped rack 17 contacts the surface of the fixed mold 1 and blocks its movement. The L-shaped rack 17 moves relative to the moving block 6 to cause the steering gear 16 to rotate and compress the spring 19. The rotation of the steering gear 16 drives the spur rack 18 to move in the opposite direction. The movement of the spur rack 18 drives the extrusion push block 20 to push the four extrusion moving blocks 12, and the deflection mechanism can perform the pushing work.

[0034] The present invention is provided with an extrusion push block 20, and utilizes the movement of the moving block 6 itself to convert into the driving force of the deflection mechanism. The hemispherical bottom of the extrusion push block 20 can push multiple deflection mechanisms at the same time, so that the demoulding work of the mobile phone protective cover can be carried out simultaneously.

[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein; and these modifications or substitutions do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
