Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: As Figures 1-4 shown, the present invention provides a technical solution: a plastic suction mold for processing plastic suction boxes that is easy to demold, including a bottom plate 1. A mounting rack 3 is fixedly connected to the center of the top end of the bottom plate 1. A fixed die 32 is fixedly connected to the top end of the mounting rack 3. Cavities 33 are symmetrically opened near the center of the top end of the fixed die 32. Top racks 34 are symmetrically and slidably inserted near the cavities 33 at the top end of the fixed die 32. Inclined plates 35 are symmetrically and fixedly connected to the bottom ends of the two top racks 34 and near the mounting rack 3. Inner grooves 13 are symmetrically opened near the mounting rack 3 inside the bottom plate 1. Slide bars 14 are slidably connected inside the inner grooves 13. Rollers 15 are fixedly connected to the top ends of the slide bars 14, and the rollers 15 cooperate with the inclined plates 35. Positioning plates 36 are symmetrically and detachably connected near the centers of both sides at the top end of the fixed die 32. A U-shaped plate 2 is fixedly connected to the top end of the bottom plate 1.

[0021] An air inlet hole 31 is opened near the center of the front end of the mounting rack 3.

[0022] By adopting the above technical solution, the mounting rack 3 is provided to open the air inlet hole 31 near the center of its front end.

[0023] Vertical plates 11 are symmetrically and fixedly connected to the bottom ends of the bottom plate 1 and near the centers of both sides.

[0024] By adopting the above technical solution, the vertical plates 11 are provided at the bottom ends of the bottom plate 1 and near the centers of both sides to rotatably mount the double-headed screw 12.

[0025] A double-headed screw 12 is rotatably connected between the two vertical plates 11, and both slide bars 14 are in threaded rotational connection with the double-headed screw 12.

[0026] By adopting the above technical solution, after the double-headed screw 12 rotates, the two slide bars 14 that are rotationally connected by threads move towards each other.

[0027] One end of one vertical plate 11 away from the double-headed screw 12 is fixedly installed with a motor 16, and the output end of the motor 16 penetrates through the vertical plate 11 and is fixedly connected to the double-headed screw 12.

[0028] By adopting the above technical solution, the motor 16 is operated, so that the fixedly connected double-headed screw 12 rotates.

[0029] An air duct 25 is fixedly connected to the inner wall of the U-shaped plate 2 and above the fixed mold 32. A plurality of nozzles 26 are fixedly connected to the bottom end of the air duct 25. A blower 27 is fixedly connected to the side end of the U-shaped plate 2, and one end of the blower 27 penetrates through the U-shaped plate 2 and is fixedly connected to the air duct 25.

[0030] By adopting the above technical solution, the blower 27 is operated, so that the generated air flow is delivered to above the fixed mold 32 through the air duct 25 and the nozzles 26.

[0031] A top cover 21 is fixedly connected to the top end of the U-shaped plate 2. An electric cylinder 22 is fixedly connected to the top end of the top cover 21 near the center. The output end of the electric cylinder 22 penetrates through the top cover 21 and is fixedly connected to a movable mold 23.

[0032] By adopting the above technical solution, the electric cylinder 22 is operated, so that the fixedly connected movable mold 23 descends.

[0033] Core molds 24 are symmetrically and fixedly connected to the bottom end of the movable mold 23 near the center, and the core molds 24 are at the same level as the cavity 33.

[0034] By adopting the above technical solution, after the movable mold 23 descends, the fixedly connected core molds 24 can descend.

[0035] Working principle: When the device is in use, first place the plastic hard sheet above the fixed mold 32. By arranging two detachable positioning plates 36 above the fixed mold 32, the effect of limiting the plastic hard sheet is realized, thereby preventing the plastic hard sheet from shifting during demolding, and further solving the problem that the device is not convenient for limiting and fixing the plastic hard sheet, which is likely to cause deviation.

[0036] By operating the electric cylinder 22, the movable mold 23 fixedly connected drives the two core molds 24 to move downward until the core molds 24 are combined with the cavity 33. Then, the air extraction pump is controlled to suck air from the air inlet hole 31. After that, the blower 27 is operated, and then, with the mutual cooperation of the air duct 25 and several nozzles 26, the plastic product after thermoforming is cooled, enabling the product to be quickly formed. When demolding is required, the motor 16 is operated, so that the double-headed screw rod 12 fixedly connected rotates, thereby causing the two slide rods 14 rotatably connected by threads to move towards each other under the action of the inner groove 13. Then, with the cooperation of the rollers 15 and the inclined plate 35, the two top frames 34 move upward, thus achieving the effect of demolding the plastic, and further solving the problem that it is inconvenient to demold the plastic and manual demolding is time-consuming and laborious.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
