The upper mold includes an upper mold base plate and an upper template. Two upper support plates are symmetrically arranged between the upper mold base plate and the upper template. A first ejector base plate and a first ejector panel are sequentially arranged at the lower end of the upper mold base plate between the two upper support plates. An upper mold core is embedded in the upper template. An ejection mechanism is also provided at the lower end of the first ejector panel. The ejection mechanism passes downward through the first upper mold core. The lower mold includes a lower mold base plate and a lower template. Two lower support plates are symmetrically arranged between the lower mold base plate and the lower template. A second ejector base plate and a second ejector panel are sequentially arranged at the upper end of the lower mold base plate between the two lower support plates. A lower mold core is embedded in the lower template. The lower mold core has a lower mold forming cavity, and the upper mold core has an upper mold forming cavity. The lower mold forming cavity and the upper mold forming cavity together form a forming cavity for forming the housing of an aviation telephone. The lower mold also includes a slanted ejector and a front fixing block and a rear fixing block for fixing the lower template and the two lower support plates; The lower end of the inclined ejector is rotatably connected to the second ejector plate, and the upper end of the inclined ejector passes through the lower mold core and extends into the molding cavity to form a snap-fit ​​protrusion with a snap-fit ​​groove for an aviation telephone shell. The inclined ejector is inclined outward from top to bottom. The front fixing block and the rear fixing block are detachably connected to the front and rear ends of the lower template and the two lower support plates, respectively. When the upper and lower templates are closed, the front fixing block and the rear fixing block connect the front and rear ends of the lower template and the two lower support plates. When the upper and lower mold plates open, the front fixing block and the rear fixing block detach from the front and rear ends of the lower mold plate and the two lower support plates, respectively, and at the same time, the locking protrusion of the inclined ejector pushes upward.

[0006] As a preferred embodiment, the ejection mechanism consists of a plurality of circular ejector pins located at the lower end of the first ejector pin panel, each circular ejector pin extending downward into the upper mold core.

[0007] As a preferred embodiment, the front and rear ends of the upper mold base plate are symmetrically provided with drive units for driving the first ejector plate to move the ejection mechanism downward.

[0008] As a preferred embodiment, the driving unit is a driving cylinder, the output shaft of the driving cylinder is connected to the first ejector base plate, and the first ejector panel is connected to the lower end face of the first ejector base plate.

[0009] As a preferred embodiment, both the front fixing block and the rear fixing block include an outer connecting block and an inner connecting block.

The upper template and the lower template are connected. The elastic expansion joint is adapted to the second groove via the first inclined surface, the vertical surface and the second inclined surface in sequence.

[0011] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, it mainly achieves product ejection while mold opening through the cooperation of the front fixing block, the rear fixing block, the inclined ejector and its locking protrusion, which greatly improves molding efficiency. Moreover, the inclined ejector can be used for both molding and ejecting products without the need for additional ejection of the locking groove. Secondly, the specific structural design of the front and rear fixing blocks facilitates the stability and reliability of the upper template's vertical displacement process. Furthermore, the cooperation of the first positioning component, the second positioning component, the first through hole, the second through hole, the first positioning groove, and the second positioning groove facilitates the pre-positioning of the front fixing block and the rear fixing block with the second ejector base plate and the second ejector panel, respectively, thereby facilitating subsequent screw fixing and preventing deviation or misalignment during installation.

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 4 As shown, a mold for manufacturing the casing of an aviation telephone includes a mating upper mold 10 and a lower mold 20.

[0019] The upper mold 10 includes an upper mold base plate 11 and an upper template 12. Two upper support plates 13 are symmetrically arranged between the upper mold base plate 11 and the upper template 12. A first ejector base plate 14 and a first ejector panel 15 are also arranged sequentially at the lower end of the upper mold base plate 11 between the two upper support plates 13.

[0020] The upper mold base plate 11 is symmetrically provided with drive units at its front and rear ends for driving the first ejector plate 15 to move the ejection mechanism downward. Preferably, the drive unit is a drive cylinder 16, the output shaft of the drive cylinder 16 is connected to the first ejector base plate 14, and the first ejector plate 15 is connected to the lower end face of the first ejector base plate 14.

[0021] The lower end of the first ejector panel 15 is also provided with an ejector mechanism; in this embodiment, the ejector mechanism is a plurality of circular ejector pins 17 provided at the lower end of the first ejector panel 15.

[0022] The upper mold plate 12 is embedded with an upper mold core 121, and the ejection mechanism passes downward through the first upper mold core 121. Preferably, each circular ejector pin 17 extends downward into the upper mold core 121.

[0023] The lower mold 20 includes a lower mold base plate 21 and a lower mold template 22. Two lower support plates 23 are symmetrically arranged between the lower mold base plate 21 and the lower mold template 22. A second ejector base plate 24 and a second ejector panel 25 are also arranged sequentially on the upper end of the lower mold base plate 21 between the two lower support plates 23. The lower mold template 22 is embedded with a lower mold core 221. The lower mold core 221 has a lower mold forming cavity 222, and the upper mold core 121 has an upper mold forming cavity 122. The lower mold forming cavity 222 and the upper mold forming cavity together form a forming cavity for forming the outer shell of an aviation telephone. The lower mold 20 also includes a slanted ejector 26 and a front fixing block 301 and a rear fixing block 302 for fixing the lower template 22 and the two lower support plates 23; The lower end of the inclined ejector 26 is rotatably connected to the second ejector plate 25, and the upper end of the inclined ejector 26 passes through the lower mold core 221, extends into the molding cavity, and forms a snap-fit ​​protrusion 261 with a snap-fit ​​groove for an aviation telephone shell. The inclined ejector 26 is inclined outward from top to bottom.

[0024] The front fixing block 301 and the rear fixing block 302 are detachably connected to the front and rear ends of the lower template 22 and the two lower support plates 23, respectively. When the upper template 12 and the lower template 22 are closed, the front fixing block 301 and the rear fixing block 302 connect the front and rear ends of the lower template 22 and the two lower support plates 23. When the upper mold plate 12 and the lower mold plate 22 are opened, the front fixing block 301 and the rear fixing block 302 are respectively separated from the front and rear ends of the lower mold plate 22 and the two lower support plates 23. At the same time, the locking protrusion 261 of the inclined ejector 26 is pushed upward.

[0025] In this embodiment, both the front fixing block 301 and the rear fixing block 302 include a first positioning member 33, a second positioning member 34, an outer connecting block 31 and an inner connecting block 32. The lower end of the outer connecting block 31 is simultaneously connected to the second ejector base plate 24 and the second ejector panel 25.

[0026] Preferably, the lower end of the external connecting block 31 is provided with a first through hole 311 and a second through hole 312, the first through hole 311 and the second through hole 312 extend in the front-back direction and the first through hole 311 is located above the second through hole 312.

[0027] The front and rear ends of the second ejector base plate 24 and the second ejector panel 25 are respectively provided with a first positioning groove 241 and a second positioning groove 251 in the first through hole 311 and the second through hole 312. The first through hole 311 and the first positioning groove 241 are located on the same axis, and the second through hole 312 and the second positioning groove 251 are located on the same axis.

[0028] The first positioning member 33 passes through the first through hole 311 and is fitted into the first positioning groove 241, while the second positioning member 34 passes through the second through hole 312 and is fitted into the second positioning groove 251. The first positioning member 33 and the second positioning member 34 complete the pre-positioning installation of the lower end of the outer connecting block 31 between the second ejector base plate 24 and the second ejector panel 25, respectively. Then, the lower end of the outer connecting block 31 is fixedly connected to the second ejector base plate 24 and the second ejector panel 25 by a screw. Similarly, the inner connecting block 32 is also fixedly connected to the lower template 22 using the same positioning member and screw combination, which will not be described further here.

[0029] The inner side of the outer connecting block 31 is recessed outward with a first groove 313. The first groove 313 has an open upper end. The inner connecting block 32 is located in the first groove 313. The lower end of the inner connecting block 32 is detachably connected to the lower template 22.

[0030] The inner side of the inner connecting block 32 is recessed outward with a second groove 321. The inner side of the upper part of the inner connecting block 32 above the second groove 321 includes a first inclined surface 322, a vertical surface 323 and a second inclined surface 324 arranged sequentially from top to bottom. The first inclined surface 322 is inclined inward from top to bottom, and the second inclined surface 324 is inclined outward from top to bottom. The lower end of the second inclined surface 324 is connected to the second groove 321. The upper template 12 has recessed mounting grooves 123 on its front and rear end faces, which connect to the second groove 321. An elastic telescopic member 35 is installed within the mounting groove 123. The upper template 12 and the lower template 22 are connected. The elastic telescopic member 35 is adapted to the second groove 321 via a first inclined surface 322, a vertical surface 323, and a second inclined surface 324. In this embodiment, the elastic telescopic member 35 includes a slider 351 slidably mounted within the mounting groove 123 and a spring 352 providing a restoring force to the slider 351. The outer surface of the slider 351 includes a third inclined surface 353, a vertical surface 354, and a fourth inclined surface 355 arranged sequentially from top to bottom. The third inclined surface 353 is inclined outwards from top to bottom, and the fourth inclined surface 355 is inclined inwards from top to bottom.

[0031] During the process of the upper template 12 connecting to the lower template 22 from top to bottom, the inner connecting block 32 remains fixed. The fourth inclined surface 355 first abuts against the first inclined surface 322. Under the force of the first inclined surface 322, the slider 351 retracts inward into the mounting groove 123. Then, the vertical surface 354 abuts against the vertical surface 323. Then, when the upper end of the vertical surface 354 is lower than the lower end of the vertical surface 323, the slider 351 extends outward from the mounting groove 123 and enters the second groove 321 under the restoring force of the spring 352.

[0032] When the upper template 12 separates from the lower template 22 from bottom to top, the slider 351 first retracts into the mounting groove 123 and then extends out of the mounting groove 123 under the reset force. When the slider 351 retracts into the mounting groove 123, the drive unit can drive the first ejector plate 14 to move downward, thereby driving the circular ejector 17 to push out the outer casing of the aviation telephone.

[0033] The key design feature of this utility model is that it achieves product ejection while the mold is being opened through the cooperation of the front fixing block, the rear fixing block, the inclined ejector and its locking protrusion, which greatly improves molding efficiency. Moreover, the inclined ejector can be used for both molding and ejecting products without the need for additional ejection of the locking groove. Secondly, the specific structural design of the front and rear fixing blocks facilitates the stability and reliability of the upper template's vertical displacement process. Furthermore, the cooperation of the first positioning component, the second positioning component, the first through hole, the second through hole, the first positioning groove, and the second positioning groove facilitates the pre-positioning of the front fixing block and the rear fixing block with the second ejector base plate and the second ejector panel, respectively, thereby facilitating subsequent screw fixing and preventing deviation or misalignment during installation.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
