When injecting materials into the cavity, the injection pipe is inserted into the feeding hole 17. At this time, after being squeezed by the injection pipe, the sealing wedge blocks 6 will move into the moving grooves 18 on both sides respectively, and then the materials are injected into the cavity through the injection pipe. After the material injection is completed, the injection pipe is taken out. At this time, the sealing wedge blocks 6 move towards each other under the action of the tension springs 19, so as to conveniently block the inside of the injection hole 17 and prevent the overflowing materials from entering the inside of the injection hole 17 too much.
[0021] Embodiment 2
[0022] In this embodiment, as Figures 1-4As shown in the figure, a rotating rod 7 is rotatably connected to the upper end of the upper mold 3. A second fixing plate 10 is fixedly sleeved on the rod wall of the rotating rod 7, and a first fixing plate 8 is fixedly installed at the upper end. A moving rod 15 is slidably connected inside the second fixing plate 10. The lower end of the moving rod 15 penetrates through the lower end of the second fixing plate 10 and is fixedly connected to a tapered block 16. The tapered block 16 is slidably connected inside the feeding hole 17 and moves to below the plugging wedge block 6. A second cylinder 9 is fixedly installed at the upper end of the first fixing plate 8. The output shaft of the second cylinder 9 passes through the inside of the first fixing plate 8 and is fixedly connected to the upper end of the moving rod 15. A sealing groove 21 is provided on the lower side wall inside the feeding hole 17, and the sealing groove 21 is provided below the plugging wedge block 6. A sealing pad 20 is fixedly sleeved on the lower side wall of the tapered block 16. The sealing pad 20 is hermetically connected to the inside of the sealing groove 21 through the tapered block 16. The bottom diameter of the tapered block 16 matches the diameter of the feeding hole 17. After the tapered block 16 is connected to the inside of the feeding hole 17, the bottom surface of the tapered block 16 is horizontal with the top of the feeding hole 17. After the tapered seat 16 moves downward, the sealing pad 20 can be connected to the inside of the sealing groove 21, so that the material entering the feeding hole 17 can be pushed into the inside of the mold cavity. Rotate the rotating rod 7 to move the tapered block 16 above the feeding hole 17, and then open the second cylinder 9 to drive the moving rod 15 to move the tapered block 16 in opposite directions, and make the tapered block 16 move into the feeding hole 17 and extrude the plugging wedge block 6, so that the tapered block 16 moves below the plugging wedge block 6.
[0023] Embodiment 3
[0024] In this embodiment, as Figures 1-4 shown, an installation plate 13 is fixedly installed at the upper end of the upper mold 3. The installation plate 13 is U-shaped. A second gear 14 is rotatably connected between the installation plate 13 and the upper mold 3. A first gear 11 is fixedly sleeved on the lower end of the rod wall of the rotating rod 7. The first gear 11 is meshed with the second gear 14. A reciprocating motor 12 is fixedly installed above the installation plate 13. The output shaft of the reciprocating motor 12 passes through the inside of the installation plate 13 and is fixedly connected to the second gear 14. When injecting material, by turning on the reciprocating motor 12 to drive the second gear 14 to drive the first gear 11 to rotate, the rotating rod 7 can be rotated to move the tapered block 16 away from above the feeding hole 17, and then the injection work can be carried out. After the injection work is completed, the tapered block 16 is moved above the feeding hole 17 through the reciprocating motor 12 again.
[0025] It should be noted that in this embodiment, when using the foaming forming mold for the armrest of the car door panel, as Figures 1-4As shown, when injecting materials, first open the first cylinder 5 to close the upper mold 3 and the lower mold 2. By turning on the reciprocating motor 12, the second gear 14 drives the first gear 11 to rotate, enabling the rotating rod 7 to rotate and move the tapered block 16 away from above the feeding hole 17. Then, the injection work is carried out. Insert the injection pipe into the interior of the feeding hole 17. At this time, after the plugging wedge block 6 is extruded by the injection pipe, it will move into the interior of the moving grooves 18 on both sides respectively. Then, inject materials into the interior of the mold cavity through the injection pipe. After the material injection is completed, take out the injection pipe. At this time, under the action of the tension spring 19, the plugging wedge block 6 moves towards each other, so as to conveniently block the interior of the feeding hole 17 and prevent the overflowing materials from entering the interior of the feeding hole 17 too much. After the injection work is completed, use the reciprocating motor 12 to move the tapered block 16 above the feeding hole 17. Subsequently, open the second cylinder 9 to drive the moving rod 15 to move the tapered block 16 towards each other, and make the tapered block 16 move into the interior of the feeding hole 17 and extrude the plugging wedge block 6, so that the tapered block 16 moves below the plugging wedge block 6. After the tapered seat 16 moves downward, the sealing gasket 20 can be connected to the interior of the sealing groove 21, so as to push the materials entering the feeding hole 17 into the interior of the mold cavity and prevent the surface of the formed materials from having edges and corners.
