[0043] A mixing chamber and an adjusting chamber are formed inside the mixing box 1; the infusion device is arranged in the mixing chamber, and the infusion device includes: two groups of liquid storage tanks 3, and different foaming agents are contained in the two groups of liquid storage tanks 3;

[0044] Two groups of pouring heads 17 arranged in the same direction, each group of pouring heads 17 is connected to the infusion device through a telescopic pipe 16, so that two different foaming agents can enter the telescopic pipe 16 for mixing, and the pouring heads 17 are used for spraying the mixed atomized foaming agent;

[0045] In this embodiment, the telescopic pipe 16 is composed of a hard straight pipe and a corrugated pipe, and the corrugated pipe part can be telescoped. As Figure 2 shown, the telescopic direction of the corrugated pipe is the vertical direction.

[0046] The adjusting device is arranged in the adjusting chamber, and the adjusting device includes two groups of connecting rings 13. Each group of connecting rings 13 is sleeved on a telescopic pipe 16 for telescoping the telescopic pipe 16 and adjusting the distance between the two groups of pouring heads 17. By moving the two groups of connecting rings 13 outwards at the same time, the telescopic pipe 16 is extended, thereby pushing the pouring head 17 to move.

[0047] In this embodiment, as Figure 2 and Figure 4 shown, the adjusting device further includes: a straight gear 10, a handwheel 11, two groups of racks 12, a limit block 14, a pull rod 15 and a spring.

[0048] Among them, the spur gear 10 is arranged in the middle inside the adjustment chamber; the bottom end of the handwheel 11 is fixedly connected to the axis of the spur gear 10 for driving the spur gear 10 to rotate; two groups of racks 12 are arranged on two sides of the spur gear 10, and the two groups of racks 12 are centrosymmetric along the axis of the spur gear 10. Each group of racks 12 is meshed with the spur gear 10, and the end of the rack 12 away from the spur gear 10 is fixedly connected to the connecting ring 13.

[0049] In this embodiment, when the spur gear 10 rotates, the two groups of racks 12 will move towards the middle or towards the outside at the same time, and the two groups of racks 12 drive the two groups of connecting rings 13 to move respectively.

[0050] The limit block 14 is arranged below the spur gear 10 and is in close contact with the spur gear 10. The limit block 14 is composed of a cross bar and two limit rods. The cross bar is located below the two limit rods and is fixedly connected to the two limit rods. By inserting the two limit rods into the tooth gaps of the spur gear 10, the rotation of the spur gear 10 is restricted; the pull rod 15 is arranged below the limit block 14 and is fixedly connected to the limit block 14. The pull rod 15 is composed of a first rod and a second rod. The bottom end of the first rod is fixedly connected to one end of the second rod. Pulling the pull rod 15 can make the limit block 14 move away from the spur gear 10; the spring is sleeved on the surface of the first rod and is located between the cross bar and the mixing tank 1. During the process of the limit block 14 moving away from the spur gear 10, the spring will be compressed.

[0051] The user pulls the pull rod 15 outwards, and the pull rod 15 drives the limit block 14 to move, so that the limit block 14 moves away from the spur gear 10. During this process, the limit block 14 compresses the spring. At this time, the user rotates the handwheel 11, and the handwheel 11 drives the spur gear 10 to rotate. The spur gear 10 makes the two groups of racks 12 move outwards at the same time. The two groups of racks 12 drive the two groups of connecting rings 13 to move respectively. The connecting ring 13 makes the telescopic pipe 16 extend, thereby pushing the pouring head 17 to move, so that the distance between the two pouring heads 17 increases, and the position can be adjusted according to the pouring ports at different positions, realizing the pouring of different molds and improving the use range of this pouring device.

[0052] When injecting into the injection port of the mold, there is an unstable phenomenon.

[0053] To solve the above problems, this embodiment proposes an implementation method. The foaming agent double-pouring device further includes: a fastening device; the fastening device is arranged on the surface of the pouring head 17 for fixing the pouring head to the injection port of the mold.

An annular chute is formed on the surface of the internal thread ring 19; the slider 20 is arranged in the annular chute and is slidably connected to the internal thread ring 19 through the annular chute. When the internal thread ring 19 moves horizontally, it will drive the slider 20 to move in the same direction; the cylindrical pin 21 is arranged on the surface of the slider 20 and is fixedly connected to the slider 20, and the slider 20 drives the cylindrical pin 21 to move; one end of the rotating member 22 close to the slider 20 is provided with a strip-shaped chute and is slidably connected to the cylindrical pin 21 through the strip-shaped chute. One side of the surface of the rotating member 22 away from the slider 20 is rotatably connected to the pouring head 17. When the cylindrical pin 21 moves, it will cause the rotating member 22 to rotate along the connection with the pouring head 17 through the sliding with the strip-shaped chute; the fastening plate 23 is arranged at one end of the rotating member 22 away from the slider 20 and is fixedly connected to the rotating member 22, and the rotating member 22 drives the fastening plate 23 to rotate.

[0056] Before injection, the user rotates the internal thread ring 19, so that the internal thread ring 19 moves horizontally along the surface of the external thread ring 18 while rotating. The internal thread ring 19 simultaneously drives the slider 20 to move horizontally, and the slider 20 simultaneously drives the cylindrical pin 21 to move. The cylindrical pin 21 causes the rotating member 22 to rotate along the connection with the pouring head 17 through the sliding with the strip-shaped chute, and the rotating member 22 drives the fastening plate 23 to rotate, so that the two fastening plates 23 cooperate together to clamp the injection port of the mold to improve the stability of the injection process.

[0057] The fastening device further includes: a fastening pad 2; the fastening pad 2 is arranged on the side of the fastening plate 23 close to the pouring head 17.

[0058] In this embodiment, the fastening pad 2 is made of rubber material, which can further improve the stability effect.

[0059] As Figure 2 shown, the infusion device further includes: two high-pressure pumps 6, a connecting pipe 4 and two main flow pipes 7.

[0060] Among them, the input end of the high-pressure pump 6 is connected to the liquid storage tank 3 through the connecting pipe 4.

[0061] In this embodiment, the model of the high-pressure pump 6 is selected according to actual needs as long as it meets the working conditions.

[0062] The input end of each main flow pipe 7 is connected to the output end of the high-pressure pump 6, and the output ends of the main flow pipes 7 are respectively connected to the two telescopic pipes 16.

[0063] In this embodiment, the high-pressure pump 6 can send two different foaming agents to the same set of telescopic tubes 16 through the main flow pipe 7 for mixing.

[0064] The infusion device further includes: a control valve 8; the control valve 8 is arranged at the cross-section position of the main flow pipe 7 for controlling the flow of the main flow pipe 7.

[0065] In this embodiment, the control valve 8 is an electromagnetic valve, and its model is selected according to actual needs as long as it meets the working conditions.

[0066] The infusion device further includes: a pneumatic balance valve 9; one end of the pneumatic balance valve 9 is communicated with the liquid storage tank 3, and the other end is communicated with the outside.

[0067] In this embodiment, the pneumatic balance valve 9 is a one-way valve that only allows outside air to enter the liquid storage tank 3.

[0068] The infusion device further includes: two groups of gaskets 5; each group of gaskets 5 is arranged between the connecting pipe 4 and the liquid storage tank 3 for forming a sealed space inside the liquid storage tank 3.

[0069] In this embodiment, the gasket 5 is made of rubber material, and the gasket 5 and the liquid storage tank 3 can be disassembled.

[0070] Working principle:

[0071] When the foaming agent double-pouring device is in use, when the user needs to adjust the distance between the two pouring heads 17, the user pulls the pull rod 15 outward; the pull rod 15 drives the limit block 14 to move, so that the limit block 14 moves away from the spur gear 10; and during this process, the limit block 14 compresses the spring; at this time, the user rotates the hand wheel 11; the hand wheel 11 drives the spur gear 10 to rotate; the spur gear 10 makes the two racks 12 move outward at the same time; the two racks 12 respectively drive the two connecting rings 13 to move; the connecting ring 13 extends the telescopic tube 16, thereby pushing the pouring head 17 to move; so that the distance between the two pouring heads 17 increases, and the position can be adjusted for pouring ports at different positions, realizing pouring of different molds and improving the use range of this pouring device.

[0072] Before injection, the user rotates the internal thread ring 19; so that the internal thread ring 19 moves horizontally along the surface of the external thread ring 18 while rotating; the internal thread ring 19 simultaneously drives the slider 20 to move horizontally; the slider 20 simultaneously drives the cylindrical pin 21 to move; the cylindrical pin 21 makes the rotating member 22 rotate along the connection with the pouring head 17 through sliding with the strip-shaped chute; the rotating member 22 drives the fastening plate 23 to rotate; so that the two fastening plates 23 cooperate together to clamp the injection port of the mold to improve the stability of the injection process.

[0073] After completing the docking with the injection port of the mold, start the high-pressure pump 6 and open the control valve 8. The high-pressure pump 6 extracts the foaming agent from the liquid storage tank 3 through the connecting pipe 4, and sends it to the two telescopic pipes 16 through the main flow pipe 7 for mixing. The mixed foaming agent is injected into the mold through the pouring head 17. During this process, the pressure inside the liquid storage tank 3 will become lower, and the pressure balance valve 9 can balance the pressure inside the liquid storage tank 3 to complete the use of this device.
