[0060] Working principle of flip chip mold:

[0061] When the mold is opened, the injection molding machine provides power, and the nozzle plate 112 first drives the panel 111 and the inclined guide assembly 15 to run 160 mm toward the side away from the panel 113 under the limit of the first pull row 32, and the two slide seats 14 run in the opposite direction respectively driven by the two inclined guide assemblies 15, and the movable mold 20 and the fixed mold 10 are kept stationary by the buckle machine 31, and the panel 113 and the A plate 114 are kept stationary by the rubber plug 18; then, the panel 111 and the nozzle plate 112 are limited by the limiter 191, and under the drive of the injection molding machine, the panel 111 moves 10 mm toward the nozzle plate 112 away from the panel 113 to expose the nozzle 70; thereafter, the injection molding machine provides power again, and the movable mold 20 runs 150 mm relative to the A plate 114, and the first The unhooking 314 leaves the latch seat 311, and the A plate 114 and the B plate 211 are disengaged from the latch machine 31. Under the limit of the third pulling row 34, the movable mold 20 continues to move toward the side of the A plate 114 away from the panel 113, and finally moves 215 mm, and the first cavity and the second cavity are opened; finally, under the limit of the second pulling row 33, the movable mold 20 drives the A plate 114 to move 5 mm toward the side away from the panel 113, that is, the panel 13 moves 5 mm relative to the A plate 114 together with the panel 113, completing the core pulling movement. The second unhooking 315 is engaged with the slider 312 in the latch machine 31, and the ejector assembly plate 213 ejects the ejector 215 30 mm, so that the sprue 70, the first product 40 in the first cavity, and the second product 60 in the second cavity can be smoothly removed;

[0062] When closing the mold, first the ejector assembly plate 213 drives the ejector 215 to return 30 mm, then the movable mold 20 moves 215 mm and closes the mold with the A plate 114, and the first unhooking 314 is engaged with the slider 312 in the latch machine 31, after which the panel 111 moves 10 mm toward the side of the sprue plate 112 and fits the sprue plate 112, finally, the sprue plate 112 drives the panel 111 and the insert 13 to move 160 mm toward the side of the panel 113, due to the action of the rubber plug 18, the sprue plate 112, the panel 111 and the panel 113 move 5 mm toward the A plate 114 together, the first movable mold core 22, the first fixed mold core 12, the insert 13 and the two slide seats 14 enclose two first cavities, the second movable mold core 24 and the second fixed mold core 193 enclose two second cavities, and through the injection of glue by the injection molding machine, the first product 40 is molded in the first cavity, and the second product 60 is molded in the second cavity.

[0063] To sum up, when the mold is opened, the nozzle plate 112 of the utility model can drive the panel 111 and the inclined guide component 15 to move toward the side away from the panel 113 under the limitation of the first pull row 32. During the operation, the two slide seats 14 are respectively driven by the two inclined guide components 15 to move in opposite directions, and the movable mold 20 is separated from the fixed mold 10 by the buckle machine 31. Then the A plate 114 moves toward the side away from the panel 113 under the limitation of the second pull row 33, so that the insert 13 performs a core pulling movement, and the insert 13 is separated from the cavity 41 of the first product 40, and finally the first product 40 after molding is taken out. The mold adopts an inverted mold and uses a limiting device 30 for sequential mold opening. The limiting device 30 is easy to manufacture, eliminates the traditional oil cylinder, and has a low cost. The entire demoulding process does not require the use of the ejector pin 215, so that the surface of the first product 40 will not have problems such as air marks and weld lines. It can be produced in large quantities and is suitable for large-scale promotion.
