Description

Technical Field

[0001] This utility model relates to the technical field of automotive roof processing equipment, and in particular to an integrated device for direct molding of PET foam automotive roofs. Background Technology

[0002] PET foam, or polyethylene terephthalate foam, boasts advantages such as high strength, good thermal insulation, sound insulation, and lightweight. Using PET foam in automotive headliners can effectively reduce vehicle weight, contributing to improved fuel economy or extended driving range for electric vehicles. It also provides some thermal and sound insulation, enhancing interior comfort. A one-piece molding machine is a device used to process PET foam material into automotive headliners, enabling integrated production from raw materials to the finished headliner. One-piece molding machines typically consist of an upper mold and a lower mold, designed and manufactured according to the shape and dimensions of the automotive headliner.

[0003] In existing technologies, due to the large size of PET foam automotive headliners, the production process requires the cooperation of multiple operators. When placing parts or removing molded components, if individual operators fail to place the raw materials neatly, resulting in their own body parts not being able to evacuate the danger zone in time, and the person operating the switch does not notice this situation and directly starts the mold, it is very easy to cause a pinching injury accident. Utility Model Content

[0004] The purpose of this invention is to address the problem in the existing technology that, due to the large volume of PET foam automotive roofs and the need for multiple operators during the production process, if some personnel fail to place the raw materials correctly or evacuate in time, or if the operator of the control device is negligent, resulting in pinching accidents when the mold is started, the invention proposes an integrated device for direct molding of PET foam automotive roofs.

[0005] The technical solution of this utility model: a PET foam car roof direct molding integrated device, including a base and a top plate, with a lower mold and an upper mold on the opposite surfaces of the base and the top plate, and further including: a pair of mounting grooves formed on the base, each mounting groove having a sliding groove inside, and an anti-pinch mechanism in both the sliding groove and the mounting groove; a support block fixedly connected to the bottom wall of the mounting groove, the top of the support block being rotatably connected to a lever mechanism that drives the anti-pinch mechanism to open.

[0006] Optionally, the anti-pinch mechanism includes a pair of L-shaped abutments disposed in the mounting groove. One end of each L-shaped abutment is fixedly connected to a locking block, and the other end of each L-shaped abutment is fixedly connected to a locking block. The interior of the sliding groove is fixedly connected to a sliding rod that movably passes through the L-shaped abutment near the locking block end. Each sliding rod is movably fitted with a spring.

[0007] Optionally, the lever mechanism includes a rocker arm rotatably connected to the top of the support block, one end of the rocker arm being fixedly connected to a foot plate, and the other end of the rocker arm being fixedly connected to a rocker block that, after abutting against the support block, drives the L-shaped support frame to open.

[0008] Optionally, the upper surface of the footplate is fixedly connected with a plurality of anti-slip strips arranged in a linear pattern.

[0009] Optionally, a cylinder is provided on the upper surface of the top plate.

[0010] Optionally, the pair of mounting slots, support blocks, rocker arms, rocker blocks, step plates, and anti-slip strips are all symmetrically arranged with the cylinder as the center.

[0011] Optionally, a pair of support plates are fixedly connected to the upper surfaces of both ends of the base, and the top ends of the support plates are fixedly connected to the lower surface of the top plate.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a combination of structures such as mounting grooves, sliding grooves, anti-pinch mechanisms, support blocks, and lever mechanisms to ensure that all operators are in their designated positions and simultaneously place their feet on the corresponding footplates during the operation of the integrated automotive roof molding equipment. Only then can the upper and lower molds of the equipment complete the closing action. This method ensures that all personnel involved in production are in a safe area, effectively preventing accidents caused by individual personnel failing to evacuate the danger zone in time, or by negligence in remaining near the mold or improper placement of raw materials, which could lead to pinching injuries during mold closure. This maximizes the protection of the operators' lives and health. Attached Figure Description

[0025] Example

[0026] like Figures 1 to 4 As shown, the PET foam car roof direct molding integrated device proposed in this utility model includes a base 1 and a top plate 2. The opposite surfaces of the base 1 and the top plate 2 are provided with a lower mold 11 and an upper mold 22. A pair of support plates 111 are fixedly connected to the upper surfaces of both ends of the base 1. The top ends of the support plates 111 are fixedly connected to the lower surface of the top plate 2. A pair of mounting grooves 12 are provided on the base 1. The interior of each mounting groove 12 is provided with a sliding groove 16. A support block 3 is fixedly connected to the bottom wall of the mounting groove 12. The support block 3 is the pry point for supporting the rocker arm 31. The closer the support block 3 is to the L-shaped support frame 13, the easier it is to step on the foot plate 33 at one end of the rocker arm 31.

[0027] Among them, such as Figures 2 to 4 As shown, both the slide groove 16 and the mounting groove 12 are equipped with anti-pinch mechanisms. The anti-pinch mechanisms include a pair of L-shaped abutments 13 disposed in the mounting groove 12. One end of each L-shaped abutment 13 is fixedly connected to a locking block 14. The thickness of the locking block 14 determines the distance at which the upper mold 22 moves to the lower mold 11 and is locked. The thicker the locking block 14, the greater the distance at which the upper mold 22 moves to the lower mold 11 and is locked, and vice versa. Therefore, the locking block 14 can be rotated as needed. The other end of each L-shaped abutment 13 is fixedly connected to a stop block 15. The shape of the stop block 15 is such that when it is pressed upward by the rocker block 32, the stop block 15 will sequentially drive the corresponding L-shaped abutment 13 and locking block 14 to move, thereby preventing the locking block 14 from locking the downward moving upper mold 22. The internal fixed connection of the slide groove 16 extends through the slide rod 161 near the end of the L-shaped abutment 13 and the locking block 14. Each slide rod 161 is movably fitted with a spring 162. The spring 162 ensures that after the L-shaped abutment 13 has opened and is no longer locked by the rocker arm 32, the elastic force of the spring 162 will cause the L-shaped abutment 13 to move the abutment 15 and the rocker arm 31 back to their original position. Figure 1 The state shown is for future use.

[0028] In addition, such as Figure 1 , Figure 2 and Figure 4As shown, a lever mechanism for opening the foot-driven anti-pinch mechanism is rotatably connected to the top of the support block 3. The lever mechanism includes a rocker arm 31 rotatably connected to the top of the support block 3. One end of the rocker arm 31 is fixedly connected to a footplate 33, and the other end of the rocker arm 31 is fixedly connected to a rocker block 32 that, after pressing against the stop block 15, drives the L-shaped stop frame 13 to open. Multiple linearly arranged anti-slip strips 34 are fixedly connected to the upper surface of the footplate 33. The surface of the anti-slip strips 34 typically has a special texture or material, which significantly increases the friction between the sole of the shoe and the footplate 33. When the operator steps on the footplate 33, even if the sole of the shoe has oil, water stains, or other substances that could easily cause slippage, the anti-slip strips 34 can effectively prevent the foot from slipping, ensuring the operator remains stable when standing on the footplate 33, thereby improving operational safety.

[0029] It is worth noting that, such as Figure 1 As shown, a cylinder 21 is provided on the upper surface of the top plate 2. The piston rod of the cylinder 21 moves through the top plate 2 and is fixedly connected to the upper surface of the upper mold 22. A pair of mounting slots 12, support block 3, rocker arm 31, rocker block 32, step plate 33 and anti-slip strip 34 are all symmetrically arranged with the cylinder 21 as the center.

[0030] In this embodiment, when a PET foam car roof direct molding integrated device is required, such as Figure 1 As shown, PET foam raw material is placed on top of the lower mold 11, and cylinder 21 on the top plate 2 is activated. The piston rod of cylinder 21 drives upper mold 22 to process the PET foam raw material on lower mold 11 into a finished car roof. However, before activating cylinder 21, a pair of operators need to step on the corresponding footplates 33. Then, footplates 33 drive one end of rocker arm 31 to move downward. Rocker arm 31 rotates through the support of support block 3, and the other end drives rocker block 32 to abut against a pair of abutment blocks 15. This causes the abutment blocks 15 to drive the mounting groove 12 to open, and the end of L-shaped abutment frame 13 away from the abutment block 15 drives the locking block 14 to slide along the slide rod 161 in the slide groove 16. This moves the locking block 14 to a position that can no longer prevent the upper mold 22 and lower mold 11 from closing. At this time, the upper mold 22 and lower mold 11 can be fully closed and the raw material can be processed and shaped. Otherwise, if any operator fails to step on the corresponding footplate 33 and moves away from the upper mold 22 that is closed by the lower mold 11, the upper mold 22 will be blocked by the corresponding pair of locking blocks 14 when it moves to the limit position, thus preventing the operator from being pinched after the upper mold 22 is completely closed by the lower mold 11.

[0031] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
