[0016] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Example: Figure 1 , Figure 2 and Figure 4 As shown, a bracket structure of a stacked injection mold is provided, comprising a mounting plate 1, a plurality of supporting plates 2 are fixedly connected to the left side of the mounting plate 1, a hollow tube 3 is embedded and fixedly connected above the plurality of supporting plates 2 on the left side of the mounting plate 1, a piston tube 4 is slidably connected inside the hollow tube 3, and a sliding rod 5 is slidably connected inside the piston tube 4; A mold cavity 6 is provided above the support plate 2, the left end of the piston tube 4 penetrates the inner side of the mold cavity 6 and is slidably connected to the mold cavity 6, and the left end of the sliding rod 5 is located inside the mold cavity 6 and is fixedly connected to a stripping plate 7; Two cover plates 8 are arranged on the left side of the mold cavity 6. The front surface and the rear surface of the mold cavity 6 are fixedly connected with a connecting piece 9. The inner sides of multiple connecting pieces 9 on the same vertical line are connected with a shaft 10 through a rotating shaft. The outer wall of the shaft 10 is located above the multiple connecting pieces 9 and is fixedly connected with a telescopic rod 11. The left end of the telescopic rod 11 is rotatably connected with a connecting piece 12 through a rotating shaft. The connecting piece 12 is fixedly connected to the opposite side of the cover plate 8. A rack 13 is embedded and fixedly connected to the front and rear surfaces of the support plate 2 located at the lower left side of the mounting plate 1. A gear 14 is fixedly connected to the bottom end of the shaft 10. The rack 13 is meshed with the gear 14. A support plate 15 is fixedly connected to the lower surface of the support plate 2 located below the left side of the mounting plate 1, and a bottom plate 16 is fixedly connected between the two support plates 15; The ends of the multiple connecting members 12 on the same vertical line away from the cover plate 8 are fixedly connected to a connecting rod 32; The device is composed of a bottom plate 16, a support plate 15, a mounting plate 1 and a support plate 2 to form a mold bracket for placing the mold. In a normal state, the cover plate 8 and the mold cavity 6 are attached together to facilitate the effect of injection molding. By moving the mold cavity 6 toward the left, the shaft 10 is rotated under the meshing transmission of the gear 14 and the rack 13, and then the two front and rear opposite cover plates 8 can be pulled apart to facilitate opening the mold cavity 6. At this time, the sliding rod 5 will slide along the piston tube 4, so that the stripping plate 7 moves with the mold cavity 6 and the internal injection mold. Then, by inflating the inside of the hollow tube 3, the piston tube 4 pushes the stripping plate 7 to the left, and then it is convenient to push the molded mold out of the mold cavity 6 through the stripping plate 7, so as to achieve the effect of easy demolding after injection molding.

[0018] like Figure 3 , Figure 6 and Figure 7 As shown, a through slot 17 is provided on the lower surface of the support plate 2 located below the left side of the mounting plate 1, and a slider 18 is fixedly connected to the lower surface of the mold cavity 6 located below the left side of the mounting plate 1 inside the through slot 17; The lower surface of the support plate 2 located below the left side of the mounting plate 1 is fixedly connected with a linkage box 19, and the interior of the linkage box 19 is rotatably connected with a gear 20 through a rotating shaft, and the front of the outer wall of the gear 20 is meshed with a rack 21, and the rear of the outer wall of the gear 20 is meshed with a rack 3 22. The right side of the rack 21 and the right side of the rack 3 22 both penetrate to the right side of the linkage box 19, and are both slidably connected with the linkage box 19. The right side of the rack 21 is integrally formed with a vertical plate 23, and the left side of the upper surface of the rack 3 22 is fixedly connected to the bottom of the slider 18; The upper surface of the bottom plate 16 is fixedly connected with a motor 24, the outer side wall of the output shaft of the motor 24 is fixedly connected with a cam 25, the bottom end of the output shaft of the motor 24 is fixedly connected with a fan-shaped abutment wheel 26, and the outer side wall of the fan-shaped abutment wheel 26 is in contact with the left side of the vertical plate 23; An air box 27 is embedded and fixed inside the support plate 15 located on the right side of the bottom plate 16.

An abutment rod 30 is fixedly connected to the left side of the piston plate 29. The left side of the abutment rod 30 penetrates to the left side of the piston plate 29 and fits with the outer side wall of the cam 25. A plurality of springs 31 are fixedly connected between the piston plate 29 and the air box 27. The starting motor 24 drives the cam 25 and the fan-shaped abutment wheel 26 to rotate together. During the rotation, the arc edge of the cam 25 will continue to abut against the abutment rod 30 for a period of time. At this time, the piston plate 29 will not be pushed, and the fan-shaped abutment wheel 26 will gradually push the vertical plate 23 to move to the right, thereby driving the gear 20 to rotate through the rack 21, so that the rack 3 22 moves to the left, and at this time, the mold cavity 6 can be driven to move to the left. As the motor 24 continues to rotate, the vertical plate 23 will not push the vertical plate 23 after contacting the arc edge of the fan-shaped abutment wheel 26. At this time, the mold cavity 6 stops moving. During the contact between the vertical plate 23 and the arc edge of the fan-shaped abutment wheel 26, the protruding end of the cam 25 will gradually contact the abutment rod 30, thereby pushing the piston plate 29 to move to the right, so that the inflation box 27 can be inflated toward the inside of the multiple inflation boxes 27 through the ventilation pipe 28, thereby realizing the function of pushing the stripping plate 7 to move and demold.

[0019] like Figure 5 As shown, two wave grooves 33 are provided on the upper left side of the mold cavity 6, and a wave column 34 is slidably connected inside the wave groove 33, and the left end of the wave column 34 is fixedly connected to the upper right side of the cover plate 8; A notch 35 is provided at the lower left side of the mold cavity 6, a limit rod 36 is fixedly connected inside the notch 35, a lifting sleeve 37 is sleeved on the outer wall of the limit rod 36, and the left side of the lifting sleeve 37 is fixedly connected to the lower right side of the cover plate 8; The lifting sleeve 37 can slide forward and backward along the limiting rod 36, and can also slide up and down. When the two front and rear opposite cover plates 8 are pulled to move away from each other, they will slide along the wave groove 33 through the wave column 34, and are limited by the lifting sleeve 37 and the limiting rod 36, so that the two cover plates 8 can shake up and down during the separation process, which is convenient for the separation between the cover plates 8 and the cooling and forming mold, making demolding more convenient.

[0020] like Figure 8 and Fig. 9 As shown, a rotating opening 38 is opened on the left side of the support plate 2, and a round rod 39 is rotatably connected to the inner side of the rotating opening 38 through a rotating shaft, and a material guide plate 40 is fixedly connected to the outer wall of the round rod 39, and the front end and the rear end of the round rod 39 respectively penetrate the front and rear of the support plate 2, and are fixedly connected to a plucking piece 41, and a plurality of extrusion push blocks 42 are fixedly connected to the outer wall of the shaft rod 10, and the plurality of extrusion push blocks 42 correspond to the plurality of plucking pieces 41 one by one; During the movement of the mold cavity 6 to the left, the extrusion push block 42 will contact the receiving piece 41 and push the receiving piece 41, so that the round rod 39 drives the guide plate 40 to rotate, thereby causing the guide plate 40 to rotate to an inclined state. When the mold cavity 6 moves to the left side of the support plate 2 and controls the stripping plate 7 to move to the left to push the cooled and formed mold out of the mold cavity 6, it can be inclinedly guided out along the guide plate 40 to achieve the effect of auxiliary material unloading.
