[0002] EPS foam is a lightweight, porous polymer manufactured by adding a blowing agent to a polystyrene resin. Upon heating, a closed honeycomb structure containing bubbles forms. EPS is classified into different grades based on its physical properties (such as density, toughness, and thermal insulation), including general-purpose, rapid prototyping, flame-retardant (self-extinguishing), non-HBCD flame-retardant, antistatic, and food-grade. After EPS foam is formed, it adheres tightly to the mold cavity, requiring tools to remove it, which takes a long time and affects mold processing efficiency. This makes it difficult to quickly remove the molded plastic from the EPS foam mold, impacting mold processing efficiency. Utility Model Content

[0022] The following is combined with Figure 1-6 This application is described in further detail.

[0023] The embodiment of the present application discloses an EPS foam plastic forming mold. Figure 1-3 , including a base 1, the upper end of the base 1 is connected to a pressing component 2, and a pressing plate 3 is connected to one side of the pressing component 2. The pressing plate 3 moves downward under the drive of the pressing component 2, and with the cooperation of the mold base 6, the mold is pressed into shape. Both sides of the lower end of the pressing plate 3 are connected to support rods 4, and both sides of the outside of the support rods 4 are provided with card slots 5. The upper end of the base 1 is connected to the mold base 6, and both sides of the outside of the mold base 6 are connected to mobile frames 7. Both sides of the mobile frame 7 are connected to mobile racks 8. One end of the mobile rack 8 extends through and extends to the inside of the mold base 6 and is connected to a lifting plate 9. The lifting plate 9 is arranged in an L-shaped structure. The lifting plate 9 fits with the mold base 6. While discharging the mold, it will not affect the normal use of the mold base 6.

[0024] Reference Figure 4-6, one end of the mobile frame 8 is connected with a round rod 10, the round rod 10 limits the mobile frame 8, the mobile frame 8 slides along the outside of the round rod 10, and then the mobile frame 8 moves in a straight line during the movement, the lower end of the round rod 10 is connected to one side of the upper end of the base 1, the upper end of the round rod 10 is connected to a mounting plate 11, the lower end of the mounting plate 11 is connected to the upper end of the base 1, and one end of the mounting plate 11 is connected to a restoration rod 12, and an arc groove 13 is provided at one end of the restoration rod 12. The arc groove 13 fits with the pull rope 17 to ensure that the restoration rod 12 and the pull rope 17 are tight, so as to avoid the pull rope 17 from being detached when the restoration rod 12 contacts the pull rope 17. A groove 14 is provided at one end of the mobile frame 8, and a slide plate 15 is connected to one side of the inside of the mobile frame 8. One end of the slide plate 15 is connected to a trapezoidal block 16, and one end of the trapezoidal block 16 is inclined The structural structure is set up. When the lower end of the support rod 4 contacts the inclined surface of the trapezoidal block 16, the trapezoidal block 16 is pushed by the support rod 4 to move into the inside of the mobile frame 8. When the trapezoidal block 16 and the card slot 5 are at the same horizontal plane, the trapezoidal block 16 moves into the inside of the card slot 5. At this time, the support rod 4 is engaged with the mobile frame 7, and one end of the trapezoidal block 16 extends through to the inside of the mobile frame 7. The other end of the slide 15 is connected to a pull rope 17. When the pull rope 17 contacts the restoration rod 12, with the cooperation of the restoration rod 12, the pull rope 17 pulls the trapezoidal block 16 to move, so that the trapezoidal block 16 is no longer connected to the support rod 4. One end of the pull rope 17 extends through to the inside of the groove 14. One end of the slide 15 is connected to a spring 18. One end of the spring 18 is connected to the inner side of the mobile frame 8, and the spring 18 is sleeved on the outside of the pull rope 17.

[0025] The implementation principle of the EPS foam plastic molding mold of the embodiment of the present application is as follows: when in use, the pressing plate 3 moves downward, and with the cooperation of the mold base 6, the mold is pressed and formed. The movement of the pressing plate 3 drives the support rod 4 to move, so that the support rod 4 moves to the inside of the moving frame 7. When the lower end of the support rod 4 contacts the inclined surface of the trapezoidal block 16, the trapezoidal block 16 is pushed by the support rod 4 to move to the inside of the moving frame 8. The trapezoidal block 16 squeezes the spring 18, so that the spring 18 is in a compressed state. When the trapezoidal block 16 and the card slot 5 are in the same horizontal plane, the trapezoidal block 16 moves to the inside of the card slot 5 under the elastic potential energy of the spring 18, and the support rod 4 It is engaged with the moving frame 7, and the pressure plate 3 moves upward. At this time, the support rod 4 drives the moving frame 7 to move, and the moving frame 7 drives the lifting plate 9 to move. The lifting plate 9 pushes the mold upward, so that the mold moves to the outside of the mold to realize automatic unloading. As the moving frame 8 moves, the lower end of the restoration rod 12 is located inside the groove 14, and the pull rope 17 is located inside the arc groove 13. With the cooperation of the restoration rod 12, the pull rope 17 is pressed down, so that the pull rope 17 drives the trapezoidal block 16 to move out of the slot 5. The support rod 4 is no longer engaged with the moving frame 7. Under the action of gravity, the moving frame 7 moves downward to its original position, and so on and so forth, to realize automatic unloading of the mold and improve the unloading efficiency.
