Description

Technical Field

[0001] This invention relates to the field of automotive roof manufacturing technology, and in particular to a flexible material hanging mechanism for roof fabric bonding molds. Background Technology

[0002] Currently, the mainstream production process for passenger car headliners uses a wet two-step process. After the substrate is formed, it is placed in a bonding mold. Workers manually lay the fabric onto the substrate at the edge of the press table, and then manually pierce the fabric with pneumatic hooks around the mold to attach the fabric before closing the mold and applying pressure. This method has the following problems: 1) The middle area of ​​the front and rear edges is far from the operator's operating area outside the press table, making it difficult for operators to manually attach the fabric to the pneumatic hooks, resulting in the risk of the front and rear edges not being properly attached; 2) After attaching and applying pressure in the middle area of ​​the front and rear edges, it is difficult for operators to remove the excess material from the hooks; 3) There is a large area of ​​ineffective material, resulting in low raw material utilization; 4) Due to the large height difference of passenger car headliners, wrinkles and other problems are prone to occur during the bonding process. Summary of the Invention

[0003] Based on the above problems, the purpose of this invention is to provide a flexible hanging mechanism for canopy fabric bonding mold, which solves the problem of difficulty in manually laying and hanging materials along the front and rear edges, reduces the wrinkles and other defects in the bonding fabric caused by failure to hang materials, and at the same time reduces the width of raw materials and lowers the cost of raw materials.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A flexible hanging mechanism for canopy fabric bonding molds includes:

[0006] The guide rod is mounted on the side wall of the lower mold body via a fixed base and can reciprocate along the mold closing direction.

[0007] The material support plate is fixed to the guide rod and floats up and down on the mold closing surface;

[0008] The hanging pin is fixed to the side wall of the lower mold body by the mounting base and can pass freely through the material support plate;

[0009] The pressure sleeve is fixed to the side wall of the upper mold body. When the mold is closed, the pressure sleeve presses down on the material support plate and is inserted into the material hanging pin.

[0010] Specifically, a spring is provided between the fixed seat and / or mounting seat and the material support plate.

[0011] Specifically, the guide rod passes through the fixed seat intermittently, and the upper end of the guide rod is threadedly connected to the material support plate, while the lower end of the guide rod is provided with an end that limits the travel on the material support plate.

[0012] Specifically, in the non-closed mold state, the top of the hanging pin does not extend beyond the material laying surface of the support plate.

[0013] Specifically, in the non-closed mold state, the material laying surface of the support plate is flush with the surface of the canopy substrate.

[0014] Specifically, the hanging pin is threaded to the mounting base, and the height of the hanging pin is adjustable.

[0015] Specifically, two guide rods are fixed to both ends of the material support plate, and two hanging nails are spaced apart between the two guide rods.

[0016] In summary, the beneficial effects of the present invention are as follows: the flexible hanging mechanism of the canopy fabric bonding mold is modified based on the existing mold, with a compact structure, reasonable and simple layout, and low failure rate. It solves the problem of difficult manual material laying and hanging nail operation at the front and rear edges, facilitates material loading and unloading, avoids poor conditions such as wrinkles in the bonding fabric, improves applicability to multiple scenarios, ensures molding effect, and effectively reduces the width of raw materials, thereby reducing raw material costs.

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1 to 4 As shown, this preferred embodiment provides a flexible material hanging mechanism for a canopy fabric bonding mold. In particular, for the middle area of ​​the front and rear edges of the mold, where the operator's operating distance is far and the material hanging is inconvenient, the mechanism includes a guide rod 1, a material support plate 2, a material hanging nail 3, and a pressure sleeve 4.

[0026] The guide rod 1 is mounted on the side wall of the lower mold body 9 via the fixed base 5 and can reciprocate along the mold closing direction. The material support plate 2 is fixed to the guide rod 1 and floats up and down on the mold closing surface. Specifically, the guide rod 1 passes through the fixed base 5 intermittently, the upper end of the guide rod 1 is threadedly connected to the material support plate 2, and the lower end of the guide rod 1 is provided with an end head 6 that limits the upper stroke of the material support plate 2.

[0027] It should be noted that, in the non-mold closed state, the material laying surface of the support plate 2 is flush with the surface of the canopy substrate in order to lay the fabric flat and avoid wrinkles.

[0028] The hanging pin 3 is fixed to the side wall of the lower mold body 9 of the mold by the mounting base 7, and can freely pass through the material support plate 2. The pressure sleeve 4 is fixed to the side wall of the upper mold body 10 of the mold. When the mold is closed, the pressure sleeve 4 presses down on the material support plate 2 and engages with the hanging pin 3 to ensure reliable hanging.

[0029] It should be noted that, in the non-mold closed state, the top of the hanging pin 3 should preferably not extend beyond the material laying surface of the material support plate 2, so as not to affect the leveling effect and make it inconvenient to remove the material.

[0030] Specifically, the hanging pin 3 is threadedly connected to the mounting base 7, and the height of the hanging pin 3 is adjustable so as to adjust the amount of the hanging pin 3 protruding relative to the material support plate 2 according to the actual situation.

[0031] According to the action requirements of the material support plate 2, it is driven by the mold closing force without the need for additional power. The fixed seat 5 or the mounting seat 7 can be respectively provided with springs 8 between the material support plate 2, so as to lay the material flat or facilitate the removal of the material when the mold is opened, and provide a certain buffer force when the mold is closed.

[0032] Preferably, two guide rods 1 are fixed to both ends of the material support plate 2, and two hanging nails 3 are spaced apart between the two guide rods 1. The specific design can be based on the edge length. In a compact structure, one guide rod 1 and one hanging nail 3 are sufficient to provide balanced support force for the material support plate 2.

[0033] Process: 1) Place the substrate on the lower mold body 9 of the bonding mold and lay the fabric flat on top of the substrate; 2) Manually hang the fabric in the easy-to-operate area with the hanging nails 3, and flatten the fabric in the difficult-to-operate area on the support plate 2; 3) The upper mold body 10 begins to press down, the pressure sleeve 4 first abuts against the fabric and the support plate 2, and during the further descent, the spring 8 is compressed, and the hanging nails 3 pierce the fabric and enter the pressure sleeve 4, thereby tightening the fabric; 4) The upper and lower molds close, and the bonding and pressure are maintained to form the product; 5) After the mold is opened, the compressed spring 8 rebounds and moves the support plate 2 upward to push the fabric out of the hanging nails 3, making it easy for the product to be manually removed.

[0034] In summary, the aforementioned flexible material hanging mechanism for the canopy fabric bonding mold is a modification of the existing mold. It features a compact structure, a reasonable and simple layout, and a low failure rate. It solves the problem of difficult manual material laying and nail hanging operations along the front and rear edges, facilitates material loading and unloading, avoids defects such as wrinkles in the bonding fabric, improves applicability to multiple scenarios, ensures molding effect, and effectively reduces the width of raw materials, thereby lowering raw material costs.

[0035] The above embodiments merely illustrate the basic principles and characteristics of the present invention. The present invention is not limited to the above examples. Various changes and modifications can be made to the present invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
