[0044] Working principle:

[0045] The stripper plate 15 and the fixed plate 2 are fixed and the movable plate 1 is driven to move backward until the rear side of the movable plate 1 and the front side of the fixed plate 2 are spliced ​​together. At this time, the stripper plate 15 maintains a certain distance from the fixed plate 2; at this time, the first forming ridge 61 on the first fixed mold core 6 and the second forming ridge 51 on the second fixed mold core 5 extend into the first forming cavity 41 on the first movable mold core 4 and the second forming cavity 31 on the second movable mold core 3 respectively.

[0046] During the movement, the movable template 1 drives the first traction rod 92 in the first end molding assembly 9 and the second traction rod 102 in the second end molding assembly 10 to move backward, thereby respectively forcing the first slider 91 and the second slider 101 to move toward the first molding cavity 41, until the first molding block 912 and the first core block 913 on the first slider 91 and the second molding block 1012 and the second core block 1013 on the second slider 101 are extended into the first molding cavity 41; at the same time, during the movement, the movable template 1 also drives the third traction rod 72 in the third end molding assembly 7 and the fourth end molding assembly 8. The fourth traction rod 82 moves backward, thereby forcing the third slider 71 and the fourth slider 81 to move toward the second molding cavity 31, until the third molding block 712 and the third core block 713 on the third slider 71 and the fourth molding block 812 and the fourth core block 813 on the fourth slider 81 extend into the interior of the second molding cavity 31; in addition, the movable template 1 will also drive the fifth traction rod 112 in the side molding assembly 11 to move backward during the movement, thereby forcing the fifth slider 111 to move toward the second molding cavity 31, until the fifth core block 1111 on the fifth slider 111 extends into the interior of the second molding cavity 31.

[0047] Next, the telescopic end of the first electric cylinder 122 in the first assembly 12 is driven to extend outward to drive the two first traction blocks 121 to move rightward at the same time, thereby driving the front sides of the first assembly block 123 and the second assembly block 124 to move toward the first molding cavity 41, until the first molding groove 1231 on the first assembly block 123 and the second molding groove 1241 on the second assembly block 124 are both assembled with the inner wall of the first molding cavity 41. At the same time, the telescopic ends of the second electric cylinder 132 in the second assembly 13 and the third electric cylinder 142 in the third assembly 14 are driven to extend outward to respectively drive the second traction block 131 and the third traction block 141 to move leftward, thereby respectively driving the third assembly block 133 and the fourth assembly block 143 to move toward the second molding cavity 31, until the third molding groove 1331 on the third assembly block 133 and the fourth molding groove 1431 on the fourth assembly block 143 are both assembled with the inner wall of the second molding cavity 31.

[0048] Next, the stripping plate 15 is driven to move toward the fixed plate 2 to force each first forming rod 16 and each second forming rod 17 to move upward or downward with the help of the seat block 18 in each snap-fit ​​forming unit, until the first base block 16 and the first protrusion 162 on each first forming rod 16 and the second base block 171 and the second protrusion 172 on each second forming rod 17 are connected with the outer wall of the first forming ridge 61 or the second forming ridge 51.

[0049] Afterwards, the molten material can be passed through the runner set in the movable template 1 into the space between the first molding ridge 61 and the first molding cavity 41 and between the second molding ridge 51 and the second molding cavity 31. After cooling, two first skeletons 19 and second skeletons 20 of different lengths but matching each other can be formed. The above principle is the existing technology.

[0050] The utility model can simultaneously complete the injection molding of the two components included in the covering frame, and does not need to separately manufacture a set of molds according to the structures of the two components, thereby reducing the mold manufacturing cost and lowering the production cost.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. 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 replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
