However, the injection, transportation and demoulding of existing plastic extruders are still driven separately, which consumes more energy during the production process.

[0003] The patent with announcement number CN118514300A discloses a plastic rubber strip extrusion molding equipment, which relates to the field of rubber strip production technology. The patent adopts a cooling pool, a heat sink, a water pump and other components to ensure that the cooling water is quickly cooled down after the high-temperature plastic rubber strip is formed, thereby improving the cooling efficiency. The gap design between the inner molding rod and the molding nozzle and the anti-swing structure ensure the molding accuracy and consistency. The heating coil heats the extrusion screw through eddy current induction to achieve efficient heating and reduce energy consumption. The multifunctional cooling system of the cooling fan and the reflux fan prevents turbulence and improves the stability of the equipment. However, the patent has the problem that the residual material on the bottom affects the docking sealing.

The overall shape of the fitting arc track 75 is an arc, and the demoulding rod 79 and the force arc track 77 fit each other. When the injection end 56 fits the top surface of the template 73 and the injection is completed, the forming mold 71 of the fitting template 73 rotates with the flip frame 62. After the fitting template 73 is separated from the fitting arc track 75, the return spring contracts and pulls the elastic rod 72 to push the template 73 away from the forming mold 71. At this time, the force rod 76 connected to the forming mold 71 contacts the force arc track 77 through the demoulding rod 79, so that the force arc track 77 pushes the demoulding rod 79 to push ... The mold rod 79 allows the demoulding rod 79 to push the force rod 76 to push the molded product out of the molding mold 71, so that the product in the molding mold 71 is separated and falls into the collection box 2 for collection.

[0031] Working principle: when the hydraulic rod 4 on the top plate 3 begins to extend downward, the hydraulic rod 4 pushes the connected pressure plate 51 to move downward, and the pressure plate 51 pushes the pressure connecting rod 52 to pass through the rod-piercing plate 53 to make the slide groove rod 54 slide downward, at this time, the injection end 56 moves downward along the slide groove rod 54 through the connected slide rod 55, so that the injection end 56 moves downward under the guidance of the inclined guide rod 57, and when the scraper 510 moves with the demoulding mechanism 7 through the bottom surface of the injection end 56, the scraper 510 first contacts the inclined surface of the injection end 56, so that the scraper 510 is pressed and pushes the spring sheet 59 to contract and slide along the side groove provided on the side of the inclined strip 58, so that the scraper 510 always fits the bottom surface of the injection end 56, and with the relative movement of the injection end 56 and the scraper 510, the material on the bottom surface of the injection end 56 is scraped clean, so as to avoid the residual material on the bottom surface of the injection end 56 affecting the butt sealing, thereby affecting the quality of injection molding;

[0032] When the slide bar 55 slides downward along the inclined guide rod 57 with the injection end 56, the slide bar 55 pushes the connected pressure push rod 63 to move, so that the pressure push rod 63 is meshed with the arc gear 67 on the rotating shaft 61 through the connected arc gear block 68, and then the pressure push rod 63 pushes the arc gear 67 to rotate through the arc gear block 68. When the side arc gear block 68 and the arc gear 67 are disengaged during the downward process of the pressure push rod 63, the lower pressure rod 64 connected to the platform plate 9 pushes the limiting bead 69 on the lower pressure block 65 to fit with the positioning groove 610 of the positioning wheel 66 under the action of the elastic force of the elastic spring, and makes the lower pressure block 65 fit with the positioning wheel 66 to prevent the positioning wheel 66 from rotating. At this time, the coaxial turning frame 62 of the positioning wheel 66 stops The rotating shaft 61 is rotated to allow the moving injection end 56 to approach the flip frame 62, and the arc gear 67 is pushed by the pressure push rod 63 to flip the flip frame 62 to quickly fit the injection mold, thereby improving the processing efficiency. At the same time, when the pressure push rod 63 moves upward with the slide bar 55, the positioning wheel 66 connected to the rotating shaft 61 is limited by the lower pressure block 65, and the pressure push rod 63 contacts the arc surface of the arc gear 67 through the arc surface of the arc tooth block 68, so that the pressure push rod 63 deflects counterclockwise around the slide bar 55, so that the pressure push rod 63 is reset to the initial position with the injection end 56, and at the same time, the lower pressure rod 64 pushes the lower pressure block 65 so that the lower pressure block 65 is limited to the positioning groove 610 through the limiting bead 69, thereby realizing the automatic positioning of the flip frame 62 after flipping;

[0033] The flip frame 62 drives the elastic rod 72 and the template 73 to rotate together with the flip frame 62 through the connected forming mold 71.

At this time, the template 73 is attached to the forming mold 71 to achieve automatic closure. When the injection end 56 is attached to the top surface of the template 73 and the injection is completed, the forming mold 71 attached to the template 73 rotates with the flip frame 62. After the attached template 73 is separated from the fitting arc track 75, the reset spring contracts and pulls the elastic rod 72 The template 73 is pushed away from the forming mold 71. At this time, the force-bearing rod 76 connected to the forming mold 71 contacts the force arc track 77 through the demoulding rod 79, so that the force arc track 77 pushes the demoulding rod 79, and the demoulding rod 79 pushes the force-bearing rod 76 to push the molded product in the forming mold 71 out, so that the product in the forming mold 71 is detached and falls into the collection box 2 for collection. When the forming mold 71 moves from the lowest point to the top of the flip frame 62, the force-bearing rod 76 and the demoulding rod 79 connected to the forming mold 71 will be reset under the action of gravity, so that the product can be automatically demoulded during the flipping process of the flip frame 62, thereby reducing energy consumption, simplifying the processing flow, and improving the processing quality and efficiency of the product.
