DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-4 This application is described in further detail.

[0018] The embodiment of the present application discloses a plastic mold pouring device, including a mold body 1, a cavity 4 is arranged inside the mold body 1, a mounting groove 5 is opened on the surface of the mold body 1, an introduction head 2 is detachably connected inside the installation groove 5, a through introduction groove 3 is opened in the introduction head 2, an opening connected to the introduction groove 3 is opened on the surface of the cavity 4, molten plastic can be transported to the inside of the cavity 4 through the introduction groove 3, a rotating plate 12 is arranged on the side of the introduction groove 3 close to the cavity 4, and a rotating mechanism is arranged on the outer surface of the rotating plate 12, and the connection and disconnection of the introduction groove 3 and the cavity 4 are controlled by rotating the rotating plate 12.

[0019] In this embodiment, by setting a rotating mechanism to cooperate with the rotating plate 12, when the injection molding machine transports the plastic solution to the cavity 4 through the introduction groove 3, the rotating mechanism can be used to drive the rotating plate 12 to rotate to a vertical state, so that a certain gap is generated between the rotating plate 12 and the inner surface of the introduction groove 3, and the plastic solution in the introduction groove 3 can flow into the cavity 4 through the gap. After the injection is completed, the rotating mechanism can be used to drive the rotating plate 12 to rotate to a horizontal state, and the rotating plate 12 can block the introduction groove 3, separating the plastic solution in the introduction groove 3 from the plastic solution in the cavity 4 to prevent them from being integrated after molding. When the product is demolded, the plastic part in the introduction groove 3 will not cause pulling on the product, causing damage to the product. In addition, by driving the rotating plate 12 to rotate back and forth by the rotating mechanism, the plastic block in the introduction groove 3 can be loosened, and the plastic block in the introduction groove 3 can be easily removed, so that the mold body 1 can continue to be used.

[0020] Furthermore, the rotating mechanism includes a pressure plate 6, a slide groove 8, a tooth plate 9, a gear 10 and a rotating rod 11. Two groups of rotating rods 11 are provided and are symmetrically installed on both sides of the rotating plate 12. Two groups of slide grooves 8 are provided and are opened on both sides of the introduction head 2. One end of the rotating rod 11 is rotatably connected to the introduction head 2 and extends into the slide groove 8, and one end of the rotating rod 11 located in the slide groove 8 is connected to the gear 10. The slide groove 8 is equipped with a tooth plate 9, and the tooth plate 9 is meshed with the gear 10. The upper end of the tooth plate 9 extends to the outside of the slide groove 8 and is connected to the pressure plate 6. The lower end of the tooth plate 9 is provided with a return mechanism.

[0021] Furthermore, the return mechanism includes a spring 13, a guide rod 14 and a cylindrical groove 15. The tooth plate 9 is provided with a cylindrical groove 15. One end of the guide rod 14 is installed in the cylindrical groove 15 to form a moving pair. The other end of the guide rod 14 is connected to the inner surface of the slide groove 8. The surface of the guide rod 14 is provided with a spring 13.

[0022] Furthermore, one end of the spring 13 is connected to the tooth plate 9, and the other end of the spring 13 is connected to the inner surface of the slide groove 8. When the tooth plate 9 moves, the spring 13 is in an extended or compressed state.

[0023] In this embodiment, by setting a rotating mechanism and a return mechanism for use in conjunction, the rotation and reset functions of the rotating plate 12 can be realized. Specifically, when the nozzle of the injection molding machine is extended and retracted close to the introduction head 2, the nozzle will push the pressure plate 6, thereby driving the tooth plate 9 to move, and the spring 13 on the tooth plate 9 is compressed, and the tooth plate 9 rotates to rotate the gear 10, the rotating rod 11 and the rotating plate 12, and the rotating plate 12 is rotated to a vertical state, so that the introduction groove 3 is connected with the cavity 4, which is convenient for the injection molding machine to transport the plastic solution to the inside of the cavity 4; after the plastic solution is input, the nozzle of the injection molding machine moves back and no longer presses the pressure plate 6, and the compressed spring 13 is reset, driving the tooth plate 9, the gear 10 and the rotating plate 12 to reset, and the rotating plate 12 can separate the plastic solution in the introduction groove 3 from the plastic solution in the cavity 4.

[0024] Furthermore, both sides of the introduction head 2 are connected to the mold body 1 by setting fixing bolts 7.

[0025] In this embodiment, during long-term use, the introduction head 2 may be damaged and need to be replaced. At this time, it is only necessary to unscrew the fixing bolts 7, remove the introduction head 2 from the installation groove 5, install a new introduction head 2, and fix it with the fixing bolts 7.
