Description

Technical Field

[0001] The invention relates to the technical field of seat production, in particular to automatic demoulding and foaming equipment for electric vehicle seats. Background Art

[0002] With the increasing awareness of environmental protection and the continuous advancement of new energy vehicle technology, the electric vehicle market is showing a rapid growth trend. As an important part of electric vehicles, the demand for electric vehicle seats has also increased significantly.

[0003] The current seat foaming equipment pours the foaming liquid into the mold through a suspended pipe, closes the mold after the foaming liquid is poured, and makes the foaming liquid expand and foam in the mold. When the foaming mold is opened, dust will be attached to the mold surface, and the foaming liquid is poured into the mold through a suspended pipe, which increases the contact area between the foaming liquid and the outside air. The foaming liquid flows faster during the pouring process, which will drive the surrounding air to flow and generate negative pressure, making the dust in the outside air easy to adhere to the foaming liquid, affecting the quality of the foamed material after foaming;

[0004] After the seat is foamed, the seat will stick to the mold due to the high temperature of the foaming material, which is not conducive to the staff to remove the mold, and it is easy to cause the seat to be damaged when it is removed while it is adhered to the mold;

[0005] Because the foaming liquid is relatively viscous, a small amount of foaming liquid will still remain in the pipe nozzle after the pipe injection is completed. If it is not cleaned in time, the foaming material will foam inside the nozzle, causing the nozzle to be blocked.

[0006] To this end, an automatic demoulding foaming device for electric vehicle seats is proposed. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. After the high-pressure air is sprayed into the mold carrier through the second vent hole, the dust originally attached to the surface of the mold carrier will float due to the action of the high-pressure airflow. After the high-pressure airflow is injected into the mold carrier, the inside of the mold carrier will be in a positive pressure state. The air inside the mold carrier will be blown out to the inside of the hollow air bin through the air holes opened on the side wall of the foaming mold. The blown air will carry away the dust inside the mold carrier, so that the inside of the mold carrier will be kept clean.

[0020] 2. The foaming liquid remaining inside the injection hole of the slot plate is thrown away from the inside of the slot plate by the centrifugal force generated when the slot plate rotates, thereby avoiding the problem that the foaming liquid remains inside the slot plate after the injection is stopped, causing blockage of the injection port of the slot plate;

[0021] 3. The continuous injection of high-pressure air makes the bottom of the foaming material separate from the sticky state of the bottom of the inner cavity of the foaming mold, and the temperature of the bottom of the foaming material is reduced by the continuous blowing of the airflow, thereby reducing the viscosity of the foaming material, making it easier for the staff to pick it up, avoiding the foaming material from sticking to the bottom of the inner cavity of the foaming mold, causing damage during the process of the staff picking it up;

[0022] 4. When the cross bar slides inside the angled tooth groove, the mold carrier plate as a whole is driven to swing and vibrate, so that the foaming liquid inside the foaming mold is shaken and spread on the bottom of the inner cavity of the foaming mold through the swing of the foaming mold. The swinging makes the components in the foaming agent evenly mixed, which helps the foaming agent to form a stable and uniform foam structure during the foaming process, avoiding the problem of the seat collapsing during use after foaming due to the uneven distribution of the foaming liquid inside the foaming mold, improving product quality, and exhausting the bubbles inside the foaming liquid through vibration, which can avoid the formation of visible holes or defects in the foaming material, affecting the appearance quality of the product, and by exhausting the bubbles, the surface of the foaming material can be made smoother, improving the aesthetics of the product;

[0023] 5. During the rotation process, the slide plate will draw air into the interior of the pressure plate through the hollow air chamber, and discharge the drawn gas outward through the connecting hose, thereby generating negative pressure inside the foaming mold. Under the negative pressure environment, the external pressure on the foaming liquid is reduced, which helps the foaming agent to expand better and form bubbles. As the external pressure decreases, the resistance encountered by the foaming agent during the expansion process will also be reduced accordingly, thereby improving the foaming efficiency. Under the negative pressure environment, the foaming agent can expand more fully and form uniform and small bubbles, making the foaming structure stable while reducing the amount of foaming agent used, which helps to reduce the cost of raw materials and improve the overall quality of the foaming material. Negative pressure can also reduce the loss of foaming agent during the foaming process and avoid waste of foaming agent due to evaporation or leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A material injection port is provided at the bottom of the groove plate 29 , and the material injection port and the guide plate 217 are at the same horizontal plane. The inner wall of the groove plate 29 blocks the second air vent 216 provided on the annular hollow plate 215 , and the top of the first air groove 214 is located below the annular hollow plate 215 .

[0045] The upper surface of the groove plate 29 is coplanar with the upper surface of the mold carrier plate 12 , and the side edge of the propeller blade 211 is in contact with the inner wall of the first hollow tube 24 .

[0046] A telescopic motor is arranged inside the control panel 15, and a foaming liquid tank and a high-pressure gas tank are arranged at the bottom of the connecting plate 23. The connecting plate 23 is connected to the foaming liquid tank and the high-pressure gas tank under the control of the control panel 15. The first tooth plate 33 and the second tooth plate 34 are equal in length, and the angled tooth groove 38 is Z-shaped and opened on the outer wall of the foaming equipment base 11.

[0047] The circular air chamber 42 is located below the hollow air chamber 41 , and a side of the hollow air chamber 41 close to the circular air chamber 42 is inclined toward the circular air chamber 42 .

[0048] The slide plate 44 is slidably fitted on the inner wall of the circular air chamber 42 , and a recovery box is placed below the connecting hose 47 and on the upper surface of the mold carrier plate 12 .

[0049] The above implementation works as follows:

[0050] The initialization steps are as follows: the staff flips the hydraulic shaft 13 through the operation control panel 15 , and after the hydraulic shaft 13 is flipped, the pressing plate 14 covers the empty foaming mold 16 .

[0051] The working steps are as follows:

[0052] The interior of the foaming mold 16 is cleaned and dusted by the pre-separation component 2:

[0053] like Figures 1 to 6As shown, after the pressing plate 14 covers the top of the foaming mold 16, the staff operates the control panel 15 to connect the high-pressure gas box with the connecting plate 23, and the high-pressure gas enters the interior of the first hollow tube 24 through the connecting plate 23. At this time, because the groove plate 29 fits the interior of the mold carrier plate 12, the high-pressure air cannot escape through the injection port at the bottom of the groove plate 29. At this time, the high-pressure air will enter the interior of the second hollow tube 210 through the first vent hole 213, and then push the annular hollow plate 215 sliding inside the groove plate 29 upward through the first gas groove 214. When the annular hollow plate 215 moves upward, the annular hollow plate 215 is no longer affected by The high-pressure air is blocked by the groove plate 29 and is ejected outward through the second vent hole 216 provided on the annular hollow plate 215. After the high-pressure air is ejected into the mold carrier plate 12 through the second vent hole 216, the dust originally attached to the surface of the mold carrier plate 12 will float due to the action of the high-pressure airflow. After the high-pressure airflow is injected into the mold carrier plate 12, the inside of the mold carrier plate 12 is in a positive pressure state at the same time. The air inside the mold carrier plate 12 is blown out to the inside of the hollow air bin 41 through the air holes provided on the side wall of the foaming mold 16. The blown air carries away the dust inside the mold carrier plate 12 together with the dust, thereby keeping the inside of the mold carrier plate 12 clean.

[0054] The foaming liquid is filled into the foaming mold 16 through the pre-separation component 2:

[0055] When the inside of the mold carrier 12 is cleaned, the staff operates the control panel 15 to disconnect the high-pressure gas box from the connecting plate 23, and causes the motor of the control panel 15 to push the support rod 22 below it to rotate around the first rotating shaft 21. After the support rod 22 rotates, it drives the connecting plate 23 and the first hollow tube 24 to move upward as a whole. After the first hollow tube 24 moves upward, the upper surface of the annular plate 25 is at the same horizontal plane as the upper surface of the foaming mold 16. Then the control panel 15 controls the foaming liquid box to be connected with the connecting plate 23, and the foaming liquid in the foaming liquid box is filled into the first hollow tube 24. During the foaming liquid gushing upward inside the first hollow tube 24, the propeller blade 211 is pushed to drive the second hollow tube 210 to start rotating as a whole. The foaming liquid gushing upward enters the interior of the slot plate 29 through the liquid injection port at the bottom of the slot plate 29, and then is sprayed into the interior of the foaming mold 16 from the liquid injection port on the side of the slot plate 29. 16, because the second hollow tube 210 is in a rotating state as a whole, the rotation of the second hollow tube 210 will cause the slot plate 29 and the guide plate 217 to rotate together, and the foaming liquid sprayed from the injection port of the slot plate 29 is affected by the rotation of the guide plate 217 and spreads out in an umbrella shape, so that the foaming liquid is evenly sprayed on the inside of the foaming mold 16. When the foaming liquid is injected, the control panel 15 controls the foaming liquid box to stop filling the first hollow tube 24 with foaming liquid. After the foaming liquid stops gushing, the propeller blades 211 will continue to rotate for a period of time due to the influence of the previous rotation inertia. The second hollow tube 210 will drive the slot plate 29 to rotate together when rotating. The foaming liquid remaining in the injection hole of the slot plate 29 is affected by the centrifugal force generated when the slot plate 29 rotates and is thrown away from the inside of the slot plate 29, thereby avoiding the problem that the foaming liquid remains in the slot plate 29 after the injection is stopped, causing the injection port of the slot plate 29 to be blocked.

[0056] Assisted demoulding of the foamed material by means of the pre-separation component 2:

[0057] When the foaming of the foaming material is completed inside the foaming mold 16, the staff operates the control panel 15 to allow the high-pressure gas inside the high-pressure gas box to fill the inside of the slot plate 29 through the first hollow tube 24, and the high-pressure air inside the slot plate 29 pushes the annular hollow plate 215 to lift upward. After the annular hollow plate 215 is lifted upward, it pushes the foaming material to move upward. When the annular hollow plate 215 moves upward to the slot plate 29 and no longer blocks the second air vent 216, the high-pressure air inside the slot plate 29 is ejected to the bottom of the foaming material through the second air vent 216. The continuous injection of high-pressure air causes the bottom of the foaming material to break away from the sticky state with the bottom of the inner cavity of the foaming mold 16, and the temperature of the bottom of the foaming material is reduced by the continuous blowing of the airflow, thereby reducing the viscosity of the foaming material, making it easy for the staff to pick it up, avoiding the problem of the foaming material sticking to the bottom of the inner cavity of the foaming mold 16 and causing damage during the staff's picking process.

[0058] Shake the foaming liquid by shaking component 3:

[0059] like Figures 5 to 7 As shown, the hydraulic shaft 13 then controls the pressing plate 14 to continue pressing down the foaming mold 16. The downward movement of the pressing plate 14 will first push the first toothed plate 33 below it to slide downward inside the limiting sleeve 31. During the downward movement of the first toothed plate 33, the gear 39 meshing with it is driven to rotate so that the second toothed plate 34 meshing with the gear 39 slides upward inside the limiting sleeve 31. The second toothed plate 34 moves upward and drives the square plate 36 fixed thereto to move upward together. The square plate 36 moves upward to squeeze the first spring 35 between it and the limiting plate 32, so that the first spring 35 is squeezed and elastically contracts. The square plate 36 moves upward and drives the cross bar 37 to move upward together. During the upward movement of the cross bar 37, its lower end is slidably connected to the folding The inside of the angle tooth groove 38 is Z-shaped and has a convex plate inside. The upward sliding of the cross bar 37 inside the angle tooth groove 38 will drive the mold carrier 12 to swing and produce slight vibration. During the swinging of the mold carrier 12, the foaming liquid inside the foaming mold 16 will be driven to shake together, and the foaming liquid is flattened on the bottom of the inner cavity of the foaming mold 16 through the swinging of the mold carrier 12. The bubbles remaining in the foaming liquid cannot be separated in time due to the viscosity of the foaming liquid. The continuous slight vibration of the mold carrier 12 will change the surface tension of the foaming liquid and generate pressure waves in the foaming liquid, thereby changing the pressure distribution in the foaming liquid, and causing the bubbles in the foaming liquid to move to the area with lower pressure above the liquid, thereby causing the bubbles in the foaming liquid to separate from the foaming liquid.

[0060] When the cross bar 37 slides inside the angled tooth groove 38, the mold carrier 12 is driven to swing and vibrate as a whole, so that the foaming liquid inside the foaming mold 16 is shaken and spread on the bottom of the inner cavity of the foaming mold 16 through the swing of the foaming mold 16. The swinging makes the components in the foaming agent evenly mixed, which helps the foaming agent to form a stable and uniform foam structure during the foaming process, avoids the problem of the seat collapsing during use after foaming due to the uneven distribution of the foaming liquid inside the foaming mold 16, improves product quality, and discharges the bubbles in the foaming liquid through vibration, which can avoid the formation of visible holes or defects in the foaming material, affecting the appearance quality of the product, and by discharging the bubbles, the surface of the foaming material can be made smoother, thereby improving the aesthetics of the product.

[0061] The foaming liquid is assisted in foaming by the auxiliary foaming component 4:

[0062] like Figure 8As shown, when the pressing plate 14 is pressed down and the inside of the foaming mold 16 is sealed, the rotation of the gear 39 will drive the first circular cover 45 and the second rotating shaft 43 fixedly connected thereto to rotate together. Because the second rotating shaft 43 rotates eccentrically inside the circular air chamber 42, the rotation of the second rotating shaft 43 drives the slide plate 44 to rotate together. During the rotation of the slide plate 44 inside the second rotating shaft 43, because the edge of the slide plate 44 is always in contact with the inner wall of the circular air chamber 42, the slide plate 44 will be in a reciprocating sliding state inside the second rotating shaft 43. During the rotation process, the slide plate 44 will exhaust gas into the inside of the pressing plate 14 through the hollow air chamber 41, and the extracted gas will be discharged through the connecting soft Tube 47 is discharged outward, thereby generating negative pressure inside the foaming mold 16. Under the negative pressure environment, the external pressure on the foaming liquid is reduced, which helps the foaming agent to expand better and form bubbles. Since the external pressure is reduced, the resistance encountered by the foaming agent during the expansion process will also be reduced accordingly, thereby improving the foaming efficiency. Under the negative pressure environment, the foaming agent can expand more fully and form uniform and small bubbles, which stabilizes the foaming structure and can also reduce the amount of foaming agent used, which helps to reduce the cost of raw materials and improve the overall quality of the foaming material. The negative pressure can also reduce the loss of the foaming agent during the foaming process and avoid waste of the foaming agent due to evaporation or leakage.
