DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-4 This application is described in further detail.

[0031] The present application embodiment discloses an injection molding device for producing an aircraft seat dining table.

[0032] In this embodiment, the U-shaped support frame 1 provided in the injection molding device for producing the aircraft seat dining table can limit the installation positions of the fixed mold 2 and the movable mold 3, and can be closed with the fixed mold 2 when the movable mold 3 moves downward, so that injection molding can be performed between the fixed mold 2 and the movable mold 3. After the injection-molded aircraft seat dining table is formed, the movable mold 3 can be controlled to move upward, and then the set adjustment mechanism 5 can be started. By starting the adjustment mechanism 5, the symmetrically set blocking head 4 can be controlled to move up and down inside the fixed mold 2 at the same time. When the blocking head 4 moves upward, it is convenient to perform injection molding inside the fixed mold 2. After the blocking head 4 moves downward, the demoulding air pump 6 can be started to transport gas to the inside of the fixed mold 2 through a plurality of air pipes 7. The transported gas can be compressed air or Inert gas, the gas can be transported into the injection molding part inside the fixed mold 2 through the hole after the sealing head 4 moves down, and then the demolding mechanism 8 is started to push the injected aircraft seat dining table out of the fixed mold 2. The present application can form an air cushion between the fixed mold 2 and the molded part through inflation, thereby reducing the contact area during demolding, reducing the force required for demolding, facilitating the demolding of the aircraft seat dining table inside the fixed mold 2, speeding up the demolding efficiency, improving the work efficiency of the staff, and avoiding as much as possible the situation where the demolding efficiency of the dining table is affected due to the relatively slow air intake speed inside the fixed mold 2 when the aircraft seat dining table is lifted by the demolding mechanism 8, so that the present application is more conducive to practical use.

[0033] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the fixed mold 2 includes a first mold body 201 located inside the U-shaped support frame 1, a plurality of support legs 202 are evenly and fixedly connected to the lower surface of the first mold body 201, the lower end surface of the support leg 202 is fixedly connected to the bottom of the inner wall of the U-shaped support frame 1, an injection cavity 203 is provided on the upper surface of the first mold body 201, and an inflation cavity 204 connected to the injection cavity 203 is symmetrically provided inside the first mold body 201, and symmetrically arranged sealing heads 4 are respectively located inside the symmetrically opened inflation cavities 204, and a plurality of air pipes 7 are respectively connected to the symmetrically opened inflation cavities 204 at one end away from the demolding air pump 6, and a storage groove 205 connected to the injection cavity 203 is provided inside the first mold body 201, and the top of the demolding mechanism 8 is located inside the storage groove 205.

The number of the plurality of air pipes 7 is two, which are respectively connected to the symmetrically opened inflation cavities 204. Therefore, when demolding, the plugging head 4 can be controlled to move downward through the adjusting mechanism 5, and then the air pipe 7 cooperates with the demolding air pump 6 to transport gas to the interior of the inflation cavity 204. The air can be transported to the interior of the injection molding cavity 203 through the inflation cavity 204, thereby improving the demolding efficiency. The storage groove 205 can limit the installation position of the top of the demolding mechanism 8.

[0035] In a further preferred embodiment of the present invention, Figure 2 As shown, the adjustment mechanism 5 includes a double-headed hydraulic cylinder 501 fixedly connected to the inside of the U-shaped support frame 1, and the output ends of the double-headed hydraulic cylinder 501 are symmetrically hinged with a straight angle code 502. The end of the straight angle code 502 away from the double-headed hydraulic cylinder 501 is hinged with a connecting strip 503, and the upper end surface of the connecting strip 503 is fixedly connected to the lower surface of the sealing head 4.

[0036] In this embodiment, starting the double-headed hydraulic cylinder 501 can simultaneously control the movement of the straight angle code 502 at both output ends. When the straight angle code 502 moves, the connecting strip 503 can control the blocking head 4 to move up and down, thereby adjusting the position of the blocking head 4.

[0037] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the demoulding mechanism 8 includes a second hydraulic cylinder 801 fixedly connected to the bottom of the inner wall of the U-shaped support frame 1, and the output end of the second hydraulic cylinder 801 is fixedly connected to a demoulding plate 802, which is located inside the storage groove 205.

[0038] In this embodiment, starting the second hydraulic cylinder 801 can control the stripping plate 802 to move up and down. When the stripping plate 802 moves down, it can be retracted into the storage groove 205. When the stripping plate 802 is put on, it can push the molded aircraft seat dining table to be demolded.

[0039] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, the movable mold 3 includes a symmetrically arranged first hydraulic cylinder 301, the upper end surface of the first hydraulic cylinder 301 is fixedly connected to the top of the inner wall of the U-shaped support frame 1, and the output end of the symmetrically arranged first hydraulic cylinder 301 is fixedly connected to the second mold body 302, and the second mold body 302 is fixedly connected to an injection port 303 that penetrates the second mold body 302.

[0041] In a further preferred embodiment of the present invention, Figure 2 , Figure 3 and Figure 4 As shown, the inner wall of the U-shaped support frame 1 is symmetrically fixedly connected with the limiting guide rod 9, and the two sides of the second mold body 302 are symmetrically fixedly connected with the slider 10, and the inner wall of the slider 10 is slidably connected with the outer wall of the limiting guide rod 9.

[0042] In this embodiment, when the second mold body 302 moves up and down, the limiting guide rod 9 cooperates with the slider 10 to guide the movement of the second mold body 302, thereby enhancing the stability of the second mold body 302 when moving.

[0043] In a further preferred embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 As shown, a plurality of positioning guide grooves 11 are evenly formed on the upper surface of the first mold body 201 , and a plurality of positioning guide pillars 12 are evenly formed on the lower surface of the second mold body 302 , and the positioning guide grooves 11 match the positioning guide pillars 12 .

[0045] The implementation principle of the injection molding device for producing aircraft seat dining table boards in the embodiment of the present application is:

[0046] When in use, by injection molding between the closed fixed mold 2 and the movable mold 3, after the molded aircraft seat dining table is formed, the movable mold 3 is controlled to move up, and then the adjustment mechanism 5 is started to control the symmetrically arranged plugging head 4 to move down, and the demoulding air pump 6 is started to transport gas to the inside of the fixed mold 2 through several air pipes 7. The gas is transported into the injection molding part inside the fixed mold 2 through the hole part after the plugging head 4 moves down, and then the demoulding mechanism 8 is started to push the molded aircraft seat dining table out of the fixed mold 2. The present application forms an air cushion between the fixed mold 2 and the molded part by inflation, thereby reducing the contact area during demoulding and reducing the force required for demoulding, making it easy to demould the aircraft seat dining table inside the fixed mold 2, speeding up the demoulding efficiency, improving the work efficiency of the staff, and avoiding as much as possible the situation that the demoulding efficiency of the dining table is affected due to the relatively slow air intake speed inside the fixed mold 2 when the aircraft seat dining table is lifted by the demoulding mechanism 8, so that the present application is more conducive to practical use.
