In addition, the active valve core 51 is driven by the driving mechanism to rotate relative to the valve body 4. During the rotation of the active valve core 51, the active valve core 51 is used to completely block the first feed port 411 and / or the first discharge port 412, so that the injection molding material from the barrel 2 to the first material trough 511 and / or the injection molding material from the first material trough 511 to the first material pipe 31 can be restricted, thereby further controlling the amount of material entering the injection mold from the barrel 2.

[0044] Alternatively, if Figure 2 , Figure 4 , Figure 8 as well as Fig. 9As shown, the foam molding machine also includes a second material pipe 32, which is connected to the injection mold, and the foam molding machine docking barrel integrated discharge valve also includes a driven valve core 52 and a transmission mechanism. A second mounting hole 42 is also provided in the valve body 4, and a second feed port 421 and a second discharge port 422 are provided on the hole wall of the second mounting hole 42. The second mounting hole 42 is parallel to the first mounting hole 41, and the second mounting hole 42 and the first mounting hole 41 are staggered in the vertical and horizontal directions. A driven valve core 52 is provided in the second mounting hole 42, and a second material trough 521 is provided on the outer side wall of the driven valve core 52. The second material trough 521 is used to communicate with the barrel 2 through the second feed port 421, and the second material trough 521 is used to communicate with the second material pipe 32 through the second discharge port 422. The outer side wall of the active valve core 51 is used to shield the second feed port 421 and / or the second discharge port 422.

[0045] The driving mechanism is in transmission connection with the driven valve core 52 via a transmission mechanism, and is used to drive the driven valve core 52 to rotate.

[0046] Specifically, a sealing gasket 33 is provided between the second material pipe 32 and the valve body 4 .

[0047] In this embodiment, during use of the foam molding machine docking barrel integrated discharge valve, the driving mechanism drives the active valve core 51, and the driving mechanism drives the transmission mechanism to drive the driven valve core 52 to rotate relative to the valve body 4, so that the first material groove 511 on the active valve core 51 is connected to the barrel 2 through the first feed port 411, and the first material groove 511 on the active valve core 51 is connected to the first material pipe 31 through the first discharge port 412, and at the same time, the second material groove 521 on the driven valve core 52 is connected to the barrel 2 through the second feed port 421. The second material trough 521 on the driven valve core 52 is connected to the second material pipe 32 through the second material outlet 422, so that the injection material in the barrel 2 can enter the first material pipe 31 through the first material feed port 411, the first material trough 511 and the first material outlet 412 in sequence, and enter the injection mold through the first material pipe 31, or enter the second material pipe 32 through the second material feed port 421, the second material trough 521 and the second material outlet 422 in sequence, and enter the injection mold through the second material pipe 32, thereby completing the foam injection molding process. At the same time, the driving mechanism drives the active valve core 51 and the driven valve core 52 to rotate relative to the valve body 4. During the rotation of the active valve core 51, the active valve core 51 is used to block a part of the first feed port 411 and / or the first discharge port 412, so that the injection molding material in the barrel 2 entering the first material trough 511 and / or the injection molding material in the first material trough 511 entering the first material pipe 31 can be reduced. During the rotation of the driven valve core 52, the driven valve core 52 is used to block a part of the second feed port 421 and / or the second discharge port 422, so that the injection molding material in the barrel 2 entering the second material trough 521 and / or the injection molding material in the second material trough 521 entering the second material pipe 32 can be reduced, thereby controlling the feed amount in the barrel 2 entering the injection mold. In addition, the driving mechanism drives the active valve core 51 and the driven relative valve body 4 to rotate. During the rotation of the active valve core 51, the active valve core 51 is used to completely block the first feed port 411 and / or the first discharge port 412, thereby limiting the injection molding material from entering the first material trough 511 from the material barrel 2 and / or limiting the injection molding material from entering the first material trough 511 into the first material pipe 31. During the rotation of the driven valve core 52, the driven valve core 52 is used to completely block the second feed port 421 and / or the second discharge port 422, thereby limiting the injection molding material from entering the second material trough 521 from the material barrel 2 and / or limiting the injection molding material from entering the second material trough 521 into the second material pipe 32, thereby further controlling the feed amount from the material barrel 2 into the injection mold.

[0048] At the same time, by arranging the second mounting hole 42 in parallel with the first mounting hole 41 and staggeredly distributing the second mounting hole 42 and the first mounting hole 41 in the vertical and horizontal directions, the second mounting hole 42 and the first mounting hole 41 can be prevented from being staggered, thereby avoiding mutual interference between the active valve core 51 and the driven valve core 52 when they are installed in the first mounting hole 41 and the second mounting hole 42, which is beneficial to ensuring the effect of the active valve core 51 and the driven valve core 52.

[0049] Alternatively, if Figure 4 and Figure 8 As shown, a plurality of driven valve cores 52 are provided, a plurality of second mounting holes 42 are opened in the valve body 4, and the plurality of driven valve cores 52 are arranged in the plurality of second mounting holes 42 in a one-to-one correspondence. The plurality of second mounting holes 42 are parallel to each other, and the plurality of second mounting holes 42 are staggeredly distributed in the vertical and horizontal directions.

[0050] In this embodiment, a plurality of driven valve cores 52 are provided, and more injection materials can be simultaneously transferred into the injection mold through more driven valve cores 52. At the same time, a plurality of second mounting holes 42 are provided in the valve body 4, so that a plurality of driven valve cores 52 can be conveniently provided. Thus, by making the plurality of second mounting holes 42 parallel to each other and staggered in both the vertical and horizontal directions, the plurality of second mounting holes 42 can be prevented from being staggered, and the plurality of driven valve cores 52 can be prevented from interfering with each other when being installed in the plurality of second mounting holes 42, which is conducive to ensuring the effect of the plurality of driven valve cores 52.

[0051] Alternatively, if Figure 6-Figure 8 As shown, the foam molding machine docking barrel integrated discharge valve also includes a bracket 8, a driving mechanism includes a servo motor, and a transmission mechanism includes a driving gear 71, a synchronous gear 72 and a driven gear 73. The servo motor is arranged on the bracket 8 and is transmission-connected to the active valve core 51. The active gear 71 is connected to the active valve core 51, the driven gear 73 is connected to the driven valve core 52, the synchronous gear 72 is rotationally connected to the valve body 4, and the synchronous gear 72 is meshed with the active gear 71 and the driven gear 73 at the same time.

[0052] Specifically, the driving gear 71 is coaxially distributed with the driving valve core 51 , and the driven gear 73 is coaxially distributed with the driven valve core 52 .

[0053] In this embodiment, the active valve core 51 is driven to rotate by the servo motor. Since the active gear 71 is connected to the active valve core 51, the active valve core 51 drives the active gear 71 to rotate when it rotates. Since the synchronous gear 72 is meshed with the active gear 71 and the driven gear 73 at the same time, the active gear 71 can sequentially drive the synchronous gear 72 and the driven gear 73 to rotate during the rotation process. Since the driven gear 73 is connected to the driven valve core 52, the driven valve core 52 is driven to rotate during the rotation process of the driven gear 73. Therefore, by setting the driving mechanism to include the servo motor, the driving gear 71, the synchronous gear 72 and the driven gear 73, the driving mechanism can be used to drive the active valve core 51 and the driven valve core 52 at the same time, and the overall structure of the integrated discharge valve of the docking barrel of the foam molding machine can be reduced.

[0054] Alternatively, if Figure 1 , Figure 2 as well as Figure 5-Figure 8 As shown, the driving mechanism further includes a reducer 61 and a coupling 62 , and the servo motor, the reducer 61 , the coupling 62 and the active valve core 51 are connected in sequence.

[0055] In this embodiment, the reducer 61 is driven to rotate by a servo motor, and the reducer 61 is connected to the active valve core 51 through a coupling 62, so that the active valve core 51 can be driven to rotate through the coupling 62. Therefore, by providing the reducer 61, the torque is increased, which is conducive to using a servo motor to drive the active valve core 51 and multiple driven valve cores 52 at the same time. At the same time, the coupling 62 is provided between the reducer 61 and the active valve core 51, and the coupling 62 can be used to compensate for the offset between the reducer 61 and the active valve core 51 due to inaccurate manufacturing and installation, deformation during operation, or thermal expansion.

[0056] Alternatively, if Figure 6 and Figure 8 As shown, the transmission mechanism further includes a bearing 74 . The active valve core 51 is sleeved with the bearing 74 , and the driven valve core 52 is sleeved with the bearing 74 .

[0057] In this embodiment, the first bearing 74 is sleeved on the active valve core 51, which can reduce the friction of the active valve core 51 relative to the hole wall of the first mounting hole 41, and the second bearing 74 is sleeved on the driven valve core 52, which can reduce the friction of the driven valve core 52 relative to the hole wall of the second mounting hole 42. Therefore, by arranging the bearings 74 on the active valve core 51 and the driven valve core 52, the friction of the active valve core 51 and the driven valve core 52 relative to the valve body 4 can be reduced, and the active valve core 51 and the driven valve core 52 can be driven to rotate by the servo motor.

[0058] Alternatively, if Fig. 9As shown, two first mounting grooves 43 are formed at both ends of the first mounting hole 41 on the valve body 4, and two second mounting grooves 44 are formed at both ends of the second mounting hole 42 on the valve body 4, and bearings 74 are disposed in the two first mounting grooves 43 and the two second mounting grooves 44;

[0059] The transmission mechanism further includes a plurality of bearing covers 75 , which are all connected to the valve body 4 and are used to limit the bearing 74 .

[0060] In this embodiment, a first mounting groove 43 is provided on the valve body 4, and a bearing 74 is provided in the first mounting groove 43. Meanwhile, a bearing cover 75 is provided at the opening of the first mounting groove 43 on the valve body 4 to block the opening of the first mounting groove 43, thereby preventing the bearing 74 in the first mounting groove 43 from being disengaged. A second mounting groove 44 is provided on the valve body 4, and a bearing 74 is provided in the second mounting groove 44. Meanwhile, a bearing cover 75 is provided at the opening of the second mounting groove 44 on the valve body 4 to block the opening of the second mounting groove 44, thereby preventing the bearing 74 in the second mounting groove 44 from being disengaged. Thus, by providing the first mounting groove 43 and the bearing cover 75, it is convenient to install and limit the bearing 74.

[0061] Alternatively, if Figure 6 As shown, the transmission mechanism further includes a skeleton shaft seal 76 and a second sealing ring 77 . The skeleton shaft seal 76 and the second sealing ring 77 are both arranged on the bearing cover 75 and are used to abut against the valve body 4 .

[0062] In this embodiment, by arranging a skeleton shaft seal 76 and a second sealing ring 77 on the bearing cover 75, the connection between the bearing cover 75 and the valve body 4 can be sealed to prevent the lubricating oil in the bearing 74 from flowing out from the gap between the bearing cover 75 and the valve body 4. In this way, the effect of the bearing 74 can be ensured.

[0063] Alternatively, if Figure 7 and Figure 8 As shown, the foam molding machine docking barrel integrated discharge valve also includes a sensing block 91 and a position sensing sensor 92 . The sensing block 91 is arranged on the bracket 8 , and the position sensing sensor 92 is arranged on the coupling 62 . The position sensing sensor 92 is used to sense the sensing block 91 .

[0064] In this embodiment, by setting a position sensing sensor 92 on the coupling 62 and setting a sensing block 91 on the bracket 8, the position sensing sensor 92 can sense the sensing block 91 to determine the rotation angle of the active valve core 51 and the driven valve core 52. Therefore, by setting the position sensing sensor 92 and the sensing block 91, the rotation angle of the active valve core 51 and the driven valve core 52 can be determined. During the rotation of the active valve core 51, the size of the active valve core 51 covering the first feed port 411 and / or the first discharge port 412 can be accurately adjusted, so that the injection molding material entering the first material trough 511 in the barrel 2 and / or the injection molding material entering the first material trough 511 into the first material pipe 31 can be controlled. During the rotation of the driven valve core 52, the size of the driven valve core 52 covering the second feed port 421 and / or the second discharge port 422 can be accurately adjusted, so that the injection molding material entering the second material trough 521 in the barrel 2 and / or the injection molding material entering the second material pipe 32 can be controlled, thereby accurately controlling the feed amount from the barrel 2 into the injection mold.

[0065] Alternatively, if Figure 7 and Figure 8 As shown, the transmission mechanism further includes an expansion sleeve 78 , and the driving gear 71 and the driving valve core 51 are connected via the expansion sleeve 78 .

[0066] In this embodiment, the driving gear 71 and the driving valve core 51 are connected via the expansion sleeve 78 , which helps to ensure that the driving gear 71 and the driving valve core 51 rotate together.
