Description

Technical Field

[0001] This utility model relates to the field of hot pressing molding equipment, and in particular to a hot pressing molding equipment for automobile roofs. Background Technology

[0002] In the production of products such as automotive and building roofs, hot pressing of heated materials is a core process. Precise molding and temperature control using molds are essential for product shaping, and the quality of this process directly impacts the product's structural strength and surface smoothness. With the increasing demand for mass production, the safety, stability, and production efficiency of molding equipment have become key concerns for the industry.

[0003] Traditional hot pressing equipment suffers from numerous technical defects, failing to meet actual production needs: First, it lacks automated material transport mechanisms, requiring manual handling of high-temperature materials to the hot pressing station. This is not only labor-intensive and inefficient, but also poses a significant safety hazard, as operators are susceptible to burns from contact with high-temperature components. Furthermore, the long waiting time during manual handling leads to rapid heat loss and poor molding results. Second, it lacks impact resistance. The moment the upper and lower molds close during hot pressing generates a significant impact force. Traditional moving mechanisms lack buffer protection, and prolonged impact can damage the tooling table or guide structure, affecting the equipment's lifespan. Third, the cooling mechanism is either missing or inadequate. After hot pressing, the product must be removed from the mold for natural cooling or rely on simple water cooling devices. This results in low cooling efficiency and uneven temperature distribution, leading to slow product setting, warping, and significantly extended production cycles. Additionally, the lack of a targeted cooling design can damage the mold due to prolonged high-temperature operation, increasing maintenance costs. Utility Model Content

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0021] This utility model provides a technical solution: a hot-press forming device for automobile roofs, such as... Figure 1 It includes a main workbench 1, a moving conveyor 2 inside the main workbench 1, a hydraulic pressing mechanism 3 at one end of the main workbench 1, and a cooling mechanism 4 on the hydraulic pressing mechanism 3.

[0022] like Figure 2 As shown, the mobile conveying mechanism 2 includes a mobile tooling table 201. A mobile groove 202 is provided on the main worktable 1. Guide rails 203 are provided on both sides of the mobile groove 202. The mobile tooling table 201 is movably disposed in the mobile groove 202. Guide grooves 204 are opened on both sides of the mobile tooling table 201. The guide rails 203 are tightly inserted into the guide grooves 204. A motor 205 is provided at one end of the main worktable 1. A lead screw 206 is connected to the output end of the motor 205. The lead screw 206 is movably disposed in the mobile groove 202. A screw hole 207 is opened below the mobile tooling table 201. The lead screw 206 is threadedly connected to the screw hole 207.

[0023] like Figure 3As shown, the hydraulic pressing mechanism 3 includes a support platform 301 and a guide rod 302. A pair of support platforms 301 are located on both sides of the movable tooling table 201, and a pair of guide rods 302 are located on the support platforms 301. A hydraulic worktable 303 is located on the top of the guide rods 302. A hydraulic press 304 is located inside the hydraulic worktable 303. The output end of the hydraulic press 304 is connected to a drive connecting plate 305. Guide sleeves 306 are provided at the four corners of the drive connecting plate 305. The guide sleeves 306 are movably mounted on the guide rods 302. A buffer pad 307 is provided at the bottom of the guide rods 302.

[0024] like Figures 3-5 As shown, the cooling mechanism 4 includes an infusion tank 401. The infusion tank 401 has an input pipe 402 connected to its input end, and the other end of the input pipe 402 is connected to an external water source. The output end of the infusion tank 401 is connected to a delivery pipe 403. A water pipe receiving box 404 is provided on one side of the infusion tank 401. An input water pipe 405 is provided inside the water pipe receiving box 404. The other end of the delivery pipe 403 is connected to the input water pipe 405. A cooling water passage 406 is provided inside the drive connection plate 305. The input end of the cooling water passage 406 is connected to the input water pipe 405. The cooling water passage 406 has two output ports 407. Each output port 407 is connected to an output pipe 408. The output pipe 408 is connected to an external water source recovery device.

[0025] like Figure 2 As shown, the movable tooling table 201 is provided with a lower mold 5, and the drive connecting plate 305 is provided with an upper mold 6 below it.

[0026] In practice, the preheated ceiling material is taken out, the motor 205 is started to drive the moving fixture 201 to the initial position, and the heated material is quickly placed in the cavity of the lower mold 5. The material positioning deviation does not exceed 2mm to avoid excessive material temperature loss.

[0027] The motor 205 rotates in the opposite direction, and through the transmission of the lead screw 206 and the screw hole 207, it drives the moving tooling table 201 to be accurately transported along the guide rail 203 to the bottom of the hydraulic pressing mechanism 3. The movement is smooth and without shaking. After it is in place, the motor 205 stops and self-locks.

[0028] The hydraulic press 304 starts, driving the connecting plate 305 to move the upper mold 6 vertically downward along the guide rod 302. The guide sleeve 306 ensures that the verticality error of the downward trajectory does not exceed 0.05mm. After the upper mold 6 and the lower mold 5 are closed, the hydraulic press 304 maintains the set pressure to complete the molding. The pressure is adjusted according to the material characteristics. When the mold is closed, the buffer sleeve 307 can buffer the instantaneous impact force to prevent the impact from damaging the moving tooling table 201.

[0029] Simultaneously with molding, the cooling mechanism 4 is activated. External cooling water enters the infusion tank 401 through the input pipe 402, and then is sent to the cooling water circuit 406 through the delivery pipe 403 and the input water pipe 405. It circulates within the drive connecting plate 305 to remove heat, allowing the molded roof to cool and solidify rapidly within the mold. The cooling water flows back to the external recovery device through the output port 407 and the output pipe 408. The cooling time is controlled according to the material thickness.

[0030] After cooling is complete, the hydraulic press 304 drives the upper mold 6 to move upward and reset, and the motor 205 drives the moving tooling table 201 to return to the initial position. The shaped canopy component is then manually removed, completing one molding cycle.
