Description

Technical Field

[0001] This utility model relates to the field of polyurethane foaming equipment, specifically to a whole vehicle carpet foaming device. Background Technology

[0002] With the development of automobile production, car carpets need to be integrally molded using polyurethane foam. In the polyurethane foam production process, polyurethane foam material is poured into the bottom of the carpet blank (also known as the carpet surface). After it cures and solidifies, it is demolded, and the entire car carpet is formed.

[0003] Currently, vehicle carpets are produced by vehicle carpet foaming equipment. However, the upper plate in the existing vehicle carpet foaming equipment does not have a locking device to lock it after it rises to the correct position, which makes the upper plate susceptible to accidental falling. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a vehicle carpet foaming device with high safety.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a whole vehicle carpet foaming device, comprising: a mold frame, an upper loading plate that can be raised and lowered, a lifting drive mechanism located above the upper loading plate for driving the upper loading plate to rise and fall, a lower loading plate located directly below the upper loading plate, a flipping drive mechanism, a sliding trolley, and a trolley drive mechanism for driving the trolley to move. The lower loading plate and the trolley are both located at the bottom of the mold frame. An upper mold is fixed on the lower surface of the upper loading plate, a lower mold is fixed on the upper surface of the lower loading plate, and a carpet positioning device is fixed on the trolley. The blank mold of the blank layer has its outer sides of the front and rear sides of the download plate hinged to the bottom of the mold frame. Driven by the flipping drive mechanism, the horizontal download plate can be flipped 90 degrees to an upright position, thus facilitating the removal of the foamed carpet from the lower mold. The upper mold has negative pressure holes, and the upper loading plate is equipped with an exhaust fan connected to these holes. When the exhaust fan is working, it generates suction in the negative pressure holes. After the download plate is driven to flip 90 degrees, it can avoid the trolley, allowing the trolley, driven by the trolley drive mechanism, to transport the carpet blank layer placed on the blank mold to the upper loading plate. Directly below, the upper platen descends under the drive of the lifting mechanism, allowing the upper mold to cover the blank mold. After the upper platen rises, the upper mold, through a negative pressure hole, sucks up the carpet blank layer, lifting it up. Then, after the lower platen returns to a horizontal position, the upper mold, driven by the upper platen, closes with the lower mold. At this time, the carpet blank layer is sandwiched between the upper and lower molds. After the foaming material poured onto the lower mold cures and forms an integral part with the carpet blank layer, the complete vehicle carpet is obtained. The feature is that an insert plate is fixed on the upper surface of the upper platen, and an upper... The elongated hole extends downwards, and a pin seat is provided at the top of the mold frame. Two load-bearing plates are provided on the pin seat, and pin holes are provided on the two load-bearing plates respectively. The two pin holes are arranged opposite each other. A pin and a cylinder for driving the pin are also provided on the pin seat. The pin is inserted into one of the pin holes. After the upper plate rises, the insert plate can be inserted between the two load-bearing plates, so that the elongated hole can be located between the two pin holes. At this time, the pin extends under the action of the cylinder and can be inserted into the two pin holes and the elongated hole. At this time, the pin can support the upper plate through the insert plate.

[0006] Furthermore, in the aforementioned whole vehicle carpet foaming device, a trigger boss is provided on the pin, and two photoelectric sensors are provided on the pin seat. When the pin is in the starting position and is inserted into only one pin hole, the trigger boss triggers one photoelectric sensor. When the pin extends and is inserted into both pin holes, the trigger boss triggers the other photoelectric sensor.

[0007] Furthermore, in the aforementioned whole-vehicle carpet foaming device: a buffer platform is provided on the trolley, and several support columns are provided between the buffer platform and the trolley. The upper end of each support column is fixed to the buffer platform, and the lower end of each support column passes through a guide hole on the trolley. The guide hole can vertically guide the support column. A spring is fitted on each support column, and the two ends of the spring abut against the trolley and the buffer platform respectively. When the buffer platform is pressed, the spring can provide a buffering force. The blank mold is installed on the buffer platform.

[0008] Furthermore, in the aforementioned whole-vehicle carpet foaming device: four columns are provided on the mold frame, and the four columns are located on the outer sides of the four corners of the upper plate. Linear guide rails are provided between the four corners of the upper plate and the four columns for vertical guidance. A gear is provided on each of the four corners of the upper plate, and a vertical rack is provided on each of the four columns. The four gears mesh with the racks that are close to them. The two gears on the front side of the upper plate are mounted on both ends of a synchronous shaft, and the two gears on the rear side of the upper plate are mounted on both ends of another synchronous shaft. The two synchronous shafts are rotatably mounted on the upper plate through bearings.

[0009] Furthermore, in the aforementioned whole-vehicle carpet foaming device, the trolley is mounted on the mold frame and can slide left and right, the trolley drive mechanism is used to drive the trolley to move left and right, and the download plate and the trolley are arranged side by side.

[0010] The advantages of this utility model are as follows: In the whole vehicle carpet foaming device, after the upper plate rises, the insert plate can be inserted between the two load-bearing plates, so that the elongated hole can be located between the two pin holes. At this time, after the pin extends under the action of the cylinder, the pin can be inserted into the two pin holes and the elongated hole. At this time, the pin can support the upper plate through the insert plate, which can effectively prevent the upper plate from falling due to accidents, thereby improving production safety.

[0015] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0016] like Figure 1 , Figure 3 As shown, the whole vehicle carpet foaming device includes: a mold frame 1, an upper loading plate 2 that can be raised and lowered, a lifting drive mechanism located above the upper loading plate 2 for driving the upper loading plate 2 to rise and fall, a lower loading plate 3 located directly below the upper loading plate 2, a tilting drive mechanism, a sliding trolley 4, and a trolley drive mechanism for driving the trolley 4 to move. In this embodiment, the lifting drive mechanism and the tilting drive mechanism are both hydraulic cylinders. The lower loading plate 3 and the trolley 4 are both located at the bottom of the mold frame 1. An upper mold is fixed on the lower surface of the upper loading plate 2, and a lower mold is fixed on the upper surface of the lower loading plate 3. A blank mold for positioning the carpet blank layer is fixed on the trolley 4. The outer side of the front and rear sides of the lower loading plate 3 is hinged to the bottom of the mold frame 1. The two ends of the tilting hydraulic cylinder are respectively hinged to the lower loading plate 3 and the bottom of the mold frame 1. After the tilting hydraulic cylinder extends, it can drive the horizontal lower loading plate 3 to tilt 90 degrees to an upright position. The upper mold is designed to facilitate the removal of the foamed carpet from the lower mold. A negative pressure hole is provided on the upper mold, and an exhaust fan connected to the negative pressure hole is installed on the upper platen 2. When the exhaust fan operates, it generates suction through the negative pressure hole. The lower platen 3 is driven to rotate 90 degrees, allowing it to avoid the trolley 4. Driven by the trolley drive mechanism, the trolley 4 transports the carpet blank placed on the blank mold to directly below the upper platen 2. After the upper platen 2 descends under the drive of the lifting drive mechanism, the upper mold covers the blank mold. When the upper platen 2 rises, the upper mold can suck up the carpet blank through the negative pressure hole, lifting it up. Then, after the lower platen 3 returns to a horizontal position, the upper mold can close with the lower mold under the drive of the upper platen 2. At this time, the carpet blank is sandwiched between the upper and lower molds. After the foaming material poured into the lower mold matures and forms an integral part with the carpet blank, the complete vehicle carpet is obtained. In this embodiment, the structure of the trolley drive mechanism includes: meshing gears and racks, with the rack mounted on the mold frame 1 and the gear mounted on the trolley and driven to rotate by a motor.

[0017] In this embodiment, as Figure 4 As shown, a plate 16 is fixed on the upper surface of the upper plate 2. An elongated hole 17 running vertically is provided on the plate 16. A pin seat 18 is provided at the top of the mold frame 1. Two load-bearing plates 19 are provided on the pin seat 18, each with a pin hole 20 arranged opposite to each other. A pin 21 and a cylinder for driving the pin 21 are also provided on the pin seat 18. The pin 21 is inserted into one of the pin holes 20. After the upper plate 2 rises, the plate 16 can be inserted between the two load-bearing plates 19, so that the elongated hole 17 is located between the two pin holes 20. At this time, the pin 21 extends under the action of the cylinder and can be inserted into both pin holes 20 and the elongated hole 17. The pin 21 then supports the upper plate 2 through the plate 16. This arrangement prevents the upper plate 2 from falling due to accidents, thereby improving production safety.

[0018] A trigger boss 22 is provided on the pin 21, and two photoelectric sensors 23 are provided on the pin holder 18. When the pin 21 is in the initial position and is inserted into only one pin hole 20, the trigger boss 22 triggers one photoelectric sensor 23. When the pin 21 extends and is inserted into both pin holes 20, the trigger boss 22 triggers the other photoelectric sensor 23. This configuration can detect whether the pin 21 has retracted into place or is fully inserted.

[0019] like Figure 2 As shown, a buffer platform 9 is installed on the trolley 4, and several support columns 10 are installed between the buffer platform 9 and the trolley 4. The upper end of each support column 10 is fixed to the buffer platform 9, and the lower end of each support column 10 passes through a guide hole on the trolley 4. The guide hole can vertically guide the support column 10. A spring 11 is fitted on each support column 10, and the two ends of the spring 11 abut against the trolley 4 and the buffer platform 9 respectively. When the buffer platform 9 is pressed, the spring 11 can provide a buffering force. The blank mold is installed on the buffer platform 9. The blank mold is only used to position the carpet blank layer. The blank mold itself is not strong. Without buffering, the blank mold will be damaged after repeated pressing by the upper mold. Therefore, by setting up the buffer platform 9, the service life of the blank mold can be greatly extended.

[0020] like Figure 1 As shown, the mold frame 1 is equipped with four columns 12, which are located on the outer sides of the four corners of the upper plate 2. Linear guide rails are installed between the four corners of the upper plate 2 and the four columns 12 for vertical guidance. A gear 13 is installed at each of the four corners of the upper plate 2, and a vertical rack 14 is installed on each of the four columns 12. The four gears 13 mesh with the racks 14 closest to them. The two gears 13 on the front side of the upper plate 2 are mounted on both ends of a synchronous shaft 15, and the two gears 13 on the rear side of the upper plate 2 are mounted on both ends of another synchronous shaft 15. The two synchronous shafts 15 are rotatably mounted on the upper plate 2 via bearings. This arrangement ensures that the upper plate 2 remains horizontal during lifting and lowering as much as possible.

[0021] In this embodiment, the trolley 4 is mounted on the mold frame 1 and can slide left and right. The trolley drive mechanism is used to drive the trolley 4 to move left and right. The download plate 3 and the trolley 4 are arranged side by side.
