Drawings
FIG. 1 is a schematic top view of an injection mold according to the present invention;
FIG. 2 is a schematic view of the cross-sectional structure of FIG. 1 taken along the direction A-A (the mold insert is located at the injection molding station);
wherein: 10. fixing a template; 11. a core plate; 12. fixing a circular insert; 13. pulling a plate; 130. an equal-height bolt; 101. a guide post; 20. moving the template; 21. a pull rod; 210. hanging holes; 211. a vertical shutter; 100. a net encapsulated product.
Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
As shown in fig. 1 and 2, an injection mold for a net rubber-coated product 100 includes a fixed mold and a movable mold, the fixed mold includes a fixed mold plate 10, a fixed mold circular insert 12 fixed on the fixed mold plate 10, and a mold core plate 11 sleeved on the periphery of the fixed mold circular insert 12, the mold core plate 11 is movable in the up-down direction, the fixed mold further includes a pulling plate 13 fixedly connected to the mold core plate 11, the movable mold includes a movable mold plate 20 and a pulling rod 21 disposed on the movable mold plate 20, the pulling rod 21 is detachably connected to the pulling plate 13, the mold core plate 11 has an injection molding station and an unloading station disposed above the injection molding station, when the injection mold is closed, the mold core plate 11 is disposed on the injection molding station, when the injection mold is opened, the pulling rod 21 can drive the pulling plate 13 to move upward, and then the pulling plate 13 drives the mold core plate 11 to move to the unloading station, and the pulling plate 13 is guided by the guide pillar 101 when moving upward and downward.
In this example, a resin shutter 211 is fixedly connected to a lower end portion of the pull rod 21, and the pull rod 21 is detachably connected to the pull plate 13 through the resin shutter 211.
Further, the tie bar 21 is movably disposed in the up-down direction with respect to the movable die plate 20. The movable die plate 20 is provided with a hanging hole 210, and the upper end of the pull rod 21 can be hung at the bottom of the hanging hole 210.
Furthermore, the fixed die plate 10 is also provided with a stopping mechanism for stopping the pulling plate 13 from continuously moving upwards after the pulling plate 13 drives the die core plate 11 to move to the unloading station. The stop mechanism includes a plurality of contoured bolts 130 disposed on the stationary platen 10. The movable template 20 is provided with avoidance holes for avoiding the equal-height bolts 130.
When the mold is opened, the movable mold moves upwards, when the movable mold starts to move upwards, the pull rod 21 is arranged in a sliding mode relative to the movable mold plate 20, so that the pull rod 21 cannot move upwards, the pull rod 21 cannot move upwards along with the movable mold until the bottom of the hanging hole 210 is abutted against the upper end of the pull rod 21, the pull rod 21 can pull the pull plate 13 upwards to separate the product from the fixed mold circular insert 12 after the molding cavity of the movable mold is separated from the product, and the pull rod 21 pulls the pull plate 13 until the mold core plate 11 is located at the unloading station, and the equal-height bolt 130 can prevent the pull plate 13 from continuing to move upwards; at this time, the resin shutter 211 on the pull rod 21 is separated from the pull plate 13, so that the movable mold is completely separated from the fixed mold, and the movable mold can continue to move upwards to complete the mold opening action; then the pulling plate 13 and the core insert thereon are returned to the initial position.
In conclusion, the injection mold for the net rubber-coated product does not need to design a material ejecting mechanism specially used for ejecting the product, after the injection molding of the product is finished, when the mold is opened, the product can be taken out by utilizing the power of the opened mold and through the matching arrangement of the pull rod and the drawing of the sliding mold core plate, the product is taken out and is synchronous with the opened mold, the product ejecting time of the material ejecting mechanism for ejecting the product is saved, the injection mold has a compact and reasonable structure, and compared with the injection mold with the material ejecting mechanism, the injection mold is simpler in overall structure, easy to assemble and low in manufacturing cost.
The present invention has been described in detail in order to enable those skilled in the art to understand the invention and to practice it, and it is not intended to limit the scope of the invention, and all equivalent changes and modifications made according to the spirit of the present invention should be covered by the present invention.
