Two demolding hooks 18 are arranged at the end part of the same driving plate 16, and the two demolding hooks 18 are arranged at an angle of 90 degrees, so that the mobile phone cover injection molding piece can be conveniently taken down from the mold core 9.
Basic structure and working principle
The basic structure of the mold comprises a movable mold 1, a fixed mold 2, a mounting plate 3 and a special demolding device 4. In the injection molding process, the movable mold 1 and the fixed mold 2 are combined together to form a complete cavity for injecting plastic and forming a mobile phone cover. The mounting plate 3 is used for mounting and fixing various driving and auxiliary components.
Demolding process
After injection molding is completed, the mold closing cylinder 5 starts to work, and the movable mold 1 is driven to move backwards through the mounting frame 6 and the guide rod 7. In this process, the sliding sleeve 11 first contacts the mounting plate 3, thereby compressing the first spring 13 and the second spring 14. This design allows the slide 8 and the core 9 to be smoothly removed from the cavity 10 of the slave 1.
Operation of the stripper
The slide 15 on the moving die 1 is a key part of the demolding device 4. When the movable die 1 starts to retreat, the mounting plate 3 gradually comes into contact with the driving plate 16, and starts to compress the third spring 23. In the process, the drive plate 16 will move along the guide groove 26 in the connecting plate 25, in particular along the inclined portion 27 thereof. When the driving post 24 reaches the junction of the inclined portion 27 and the vertical portion 28, the knock out hook 18 will accurately catch the edge of the case.
Hook and reset mechanism
The design of the release hook 18 is very smart, it is connected to the drive plate 16 by a spindle 17 and is provided with a torsion spring 19 to ensure that the release hook 18 fits tightly against the rim of the cell phone case. When the mobile phone cover is successfully taken off, each part can be quickly reset under the action of the respective spring, so that preparation is made for the next injection molding.
Stability and efficiency
To ensure stability of the drive plate 16 during movement, its width is matched to the slide 15 and one side is always in contact with the connecting plate 25. In addition, the combination of the plurality of drive posts 24 and guide slots 26 further enhances stability. The hemispherical contact portion 22 not only reduces friction with the movable die 1, but also ensures smooth expansion and contraction of the third spring 23.
The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
