Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile injection molding production, specifically to a demolding device for automobile injection molding production. BACKGROUND

[0002] The automobile display screen is a special display installed in the vehicle, and is an important component of the automobile audio-video system. It functions as a color TV in a home theater and can receive vehicle audio-video signals and play them back on the display. The automobile display screen is usually installed through a support. During production, injection molding is often used to produce the automobile display screen. The existing automobile display screen injection molding part is generally composed of a movable mold, a fixed mold, an injection port, and a driving part. When the driving part drives the movable mold to move, the mold can be opened and closed. When the mold is closed, the injection port can be used for injection molding. After injection molding is completed, the mold is opened, and the injection-molded automobile display screen is removed.

[0003] The existing patent CN202323628172.7 discloses an automobile display screen injection molding part that is easy to demold. The movable mold moves to the left and contacts the left side plate through the two connecting discs. During the continuous leftward movement of the movable mold, the injection-molded automobile display screen is easily ejected through the movable plate, and the two compression springs are compressed at the same time. When the mold is closed, the two connecting discs are separated from the left side plate, and the two compression springs force the two connecting discs, the two sliding rods, and the movable plate to move to the left until the movable plate is pressed against the limiting ring. At this time, the right side of the movable plate corresponds to the left side of the inner wall of the mold cavity, and the injection molding can be performed again. After the injection molding is completed, the injection-molded automobile display screen can be pushed out through the same principle, thereby achieving the characteristics of easy demolding and smooth removal of the automobile display screen.

[0004] However, in the comparative example, the movable mold and the fixed mold are directly fixed on the injection molding device, and the movable mold and the fixed mold cannot be easily disassembled from the injection molding device. According to different vehicle models or different positions of different display screens, different movable molds and fixed molds are required to injection mold display screen injection molding parts of different shapes. Because the movable mold and the fixed mold in the comparative example cannot be easily disassembled from the injection molding device, the comparative example cannot injection mold display screen injection molding parts of different shapes, and the practicality and flexibility of the comparative example are weak.

As described above, when the fixed mold 14 needs to be installed, the pushing block 20 needs to be pushed first, so that the pushing block 20 drives the limiting block 19 to rotate around the rotating rod 18. In this process, the clock spring 17 is tightened. When the limiting block 19 is rotated to a horizontal state, the limiting block 19 is located outside the first connecting slot 16 at this time. At this time, the two connecting blocks 21 are slid into the two fixed blocks 15, and the fixed mold 14 is tightly attached to the right support block 2. At this time, the pushing block 20 is loosened. Under the action of the released elastic force of the clock spring 17, the limiting block 19 returns to the vertical state.

Therefore, the efficiency of replacing the fixed mold 14 is higher, the demolding device for automobile injection molding part production can process different automobile injection molding parts, and manpower is saved, so that the practicality of the demolding device for automobile injection molding part production is increased.

[0095] As described above, in the present scheme, in use, the electric push rod 4 is started, the electric push rod 4 pushes the second positioning block 5, so that the second positioning block 5 can drive the first dismounting mechanism and the movable mold 8 to move right, so that the movable mold 8 covers the fixed mold 14, at this time, the injection molding is carried out between the movable mold 8 and the fixed mold 14 through the injection hole 22, when the injection molding between the movable mold 8 and the fixed mold 14 is formed and fixed, the electric push rod 4 is started, the first dismounting mechanism and the movable mold 8 are driven to move left, and then the movable mold 8 and the injection molding are driven to move left, in the process of continuously moving left by the electric push rod 4, the positioning plate 26 will contact the right surface of the first positioning block 3, so that the left first spring 7 is compressed and deformed, and in this process, the second positioning block 5 and the push rod 6 are relatively moved, and the right first spring 7 receives insufficient force to deform at this time, and then the push rod 6 will move right relative to the movable mold 8, and the right end of the push rod 6 will extend out of the right surface of the movable mold 8, and then the automobile injection molding in the movable mold 8 is pushed out, and the demolding of the automobile injection molding is realized, without manual demolding, saving manpower and being more convenient.
