The moving rod is connected to the vacuum chuck through the mounting rod, so that the vacuum chuck can move above the forming die to suck out the workpiece. Subsequently, when the vacuum chuck adsorbing the workpiece moves above the collection box, the second driving motor drives the second lead screw to run in the reverse direction, so that the tripod moves down to above the collection box, and the vacuum chuck releases the adsorbed workpiece and makes it fall into the collection box for collection. Thus, it is convenient to quickly feed the workpiece on the forming die, and therefore greatly improves the feeding efficiency of the forming machine;

[0015] Second, after each feeding, since the collection box is inserted into the positioning groove of the positioning seat, and the high-frequency electric push rod on the mounting plate starts, its output end quickly reciprocates to drive the positioning seat to slide, so that the small rubber workpieces in the collection box keep shaking. Through shaking, the gaps between the small rubber workpieces can be reduced and they are arranged more compactly, and more can be collected. Description of the Drawings

Detailed implementation manners

[0021] Refer to Figures 1 to 4 , in this embodiment, an automatic rubber injection molding machine includes a base 1. A machine body 2 is provided at the upper end of the base 1. An injection head 11 is provided on the front surface of the upper end of the machine body 2. A lifting seat 3 is movably connected to the lower end of the injection head 11. An injection mold 4 is provided inside the lower end of the lifting seat 3. A forming mold 9 is provided on the front surface of the machine body 2. A blanking mechanism 6 is provided on the left side of the machine body 2. A vacuum suction cup 8 is fixedly installed on the outside of the blanking mechanism 6 by screws. A collection mechanism 5 is provided on the left side of the machine body 2. A collection box 7 is inserted into the upper end of the collection mechanism 5; the basic working principle of this automatic injection molding machine is as follows: the mold clamping system on the machine body 2 operates to move the lifting seat 3 and make the injection mold 4 at its lower end be clamped with the forming mold 9. Then, through the operation of the injection system of the machine body 2, the rubber material is injected into the cavity of the forming mold 9 through the injection mold 4 by a piston with a certain pressure and speed. The rubber material in the mold undergoes a vulcanization reaction under the action of the heating system, that is, the cross-linking and curing process of rubber. This automatic rubber injection molding machine is a product that already exists in the market. Therefore, as prior art, no more details will be described here;

[0022] The blanking mechanism 6 includes a second moving groove 607 and a mounting groove 6010. The second moving groove 607 is formed on the left side of the machine body 2. A second lead screw 608 is rotatably connected to the inner side of the second moving groove 607. A second driving motor 609 is fixedly installed on the inner side of the mounting groove 6010. The lower end of the second lead screw 608 extends into the inner side of the mounting groove 6010 and is fixedly installed with the output end of the second driving motor 609. A tripod 603 is threadedly connected to the outer side of the second lead screw 608. The tripod 603 is slidably connected to the inner side of the second moving groove 607. A first moving groove 604 is formed on the front surface of the tripod 603. A first lead screw 606 is rotatably connected to the inner side of the first moving groove 604. A first driving motor 605 is fixedly installed at the left end of the tripod 603. One end of the first lead screw 606 penetrates through the first moving groove 604 and is fixedly installed with the output end of the first driving motor 605. A moving rod 602 is threadedly connected to the outer side of the first lead screw 606. One end of the moving rod 602 is slidably connected to the inner side of the first moving groove 604. Opposite ends of the moving rod 602 away from the first moving groove 604 are symmetrically and fixedly installed with mounting rods 601. The vacuum suction cups 8 are fixedly installed on the opposite sides of the mounting rods 601 by screws. By driving the second lead screw 608 to rotate in the second moving groove 607 by the output end of the second driving motor 609, the tripod 603 threadedly connected to the outer side can slide up and down at the second moving groove 607. When blanking, the tripod 603 rises. Then, the output end of the first driving motor 605 drives the first lead screw 606 to rotate at the first moving groove 604 of the tripod 603, which also enables the moving rod 602 threadedly connected to the outer side of the first lead screw 606 to move towards the direction of the machine body 2. Since the moving rod 602 is connected to the vacuum suction cups 8 through the mounting rods 601, the vacuum suction cups 8 can move above the forming die 9 to suck out the workpieces. Subsequently, when the vacuum suction cups 8 adsorbing the workpieces move above the collection box 7, the second driving motor 609 drives the second lead screw 608 to run in the reverse direction, so that the tripod 603 moves down to above the collection box 7, and the vacuum suction cups 8 release the adsorbed workpieces, causing them to fall into the collection box 7 for collection. Thus, it is convenient to quickly blank the workpieces on the forming die 9, and therefore the blanking efficiency of this forming machine is greatly improved;

[0023] The collection mechanism 5 includes a mounting plate 502 which is fixedly installed on the left side of the machine body 2. A positioning seat 503 is slidably connected to the upper end of the mounting plate 502. A high-frequency electric push rod 501 is fixedly installed at the upper end of the mounting plate 502. The output end of the high-frequency electric push rod 501 is fixedly installed with the left side of the positioning seat 503. A positioning groove 504 is formed at the upper end of the positioning seat 503. The lower end of the collection box 7 is inserted into the positioning groove 504. Through the collection mechanism 5, the workpiece can be collected in cooperation with the feeding mechanism 6. After each feeding, since the collection box 7 is inserted into the positioning groove 504 of the positioning seat 503, the high-frequency electric push rod 501 on the mounting plate 502 is started, and its output end quickly reciprocates to drive the positioning seat 503 to slide, so that the collection box 7 on the positioning seat 503 keeps shaking, which can evenly collect the workpieces in the collection box 7, reduce the gap between the workpieces and collect more workpieces.

[0024] Reference Figure 3 , symmetrically fixed sliders 14 are installed inside the first moving groove 604. One end of the moving rod 602 is slidably connected to the outside of the slider 14. A first screw sleeve 13 is fixedly installed inside one end of the moving rod 602. The moving rod 602 is threadedly connected to the outside of the first lead screw 606 through the first screw sleeve 13. By rotating the first lead screw 606 in the first moving groove 604, one end of the moving rod 602 with the first screw sleeve 13 slides at the slider 14 in the first moving groove 604, which can improve the stability of the moving rod 602.

[0025] Reference Figure 3 and Figure 4 , a second screw sleeve 15 is fixedly connected inside the tripod 603. One side of the tripod 603 is threadedly connected to the outside of the second lead screw 608 through the second screw sleeve 15. Symmetrically arranged sliding grooves 16 are formed inside the second moving groove 607. One side of the tripod 603 is slidably connected to the sliding groove 16. By rotating the second lead screw 608 inside the second moving groove 607, the tripod 603 with the second screw sleeve 15 threadedly connected to the outside of the second lead screw 608 slides at the sliding groove 16, which can improve the stability of the tripod 603.

[0026] Reference Figure 2 , symmetrically fixed support rods 10 are installed at the lower end of the mounting plate 502. The end of the support rod 10 away from the mounting plate 502 is fixedly installed with the left side of the machine body 2. Symmetrically fixed slide rails 12 are installed at the upper end of the mounting plate 502. The lower end of the positioning seat 503 is slidably connected to the slide rail 12. By adding the support rods 10 between the mounting plate 502 and the machine body 2, the stability of the mounting plate 502 can be improved, and the positioning seat 503 slides on the slide rail 12, which can improve the stability of the movement of the positioning seat 503.

[0027] Principle of use and advantages: During use, when blanking is required, the output end of the second drive motor 609 drives the second lead screw 608 to rotate in the second moving groove 607, so that the tripod 603 connected by external threads can slide up and down at the second moving groove 607. When blanking, the tripod 603 rises. Then, the output end of the first drive motor 605 drives the first lead screw 606 to rotate at the first moving groove 604 of the tripod 603, and also enables the moving rod 602 connected by external threads to the outside of the first lead screw 606 to move towards the machine body 2. The moving rod 602 is connected to the vacuum suction cup 8 through the mounting rod 601, so that the vacuum suction cup 8 can move above the forming die 9 to suck out the workpiece. Subsequently, when the vacuum suction cup 8 adsorbing the workpiece moves above the collection box 7, the second drive motor 609 drives the second lead screw 608 to run in the reverse direction, so that the tripod 603 moves down to above the collection box 7, and the vacuum suction cup 8 releases the adsorbed workpiece and drops it into the collection box 7 for collection;

[0028] After each blanking, since the collection box 7 is inserted into the positioning groove 504 of the positioning seat 503, the high-frequency electric push rod 501 on the mounting plate 502 is started, and its output end quickly reciprocates to drive the positioning seat 503 to slide, so that the collection box 7 on the positioning seat 503 keeps shaking, which can evenly collect the workpieces in the collection box 7 and reduce the gap between the workpieces.
