[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1

[0024] like Figure 1-4 As shown, this utility model provides a car roof forming mold, including a base plate 1. One end of the base plate 1 is fixedly connected to a lower mold mounting groove 2. A lower mold 21 is movably engaged with the inner side of the lower mold mounting groove 2. Several electric push rods 22 are fixedly connected to the inner side of the lower mold mounting groove 2. A clamping assembly 3 is provided on the top surface of the lower mold mounting groove 2. The clamping assembly 3 includes a mounting plate 31. A groove 312 is formed in the center of the mounting plate 31. A first drive assembly 32 is symmetrically fixedly mounted on one end of the mounting plate 31. The output ends of the two first drive assemblies 32 are drivenly connected to a bidirectional lead screw 33. A clamping support frame 34 is threadedly connected to the outer side of the bidirectional lead screw 33. A conveyor wire is threadedly connected to one side of the mounting plate 31. One end of the conveying screw 35 is connected to the second drive assembly 36, and the other end of the base plate 1 is fixedly connected to the lower mold storage box 4. The other end of the conveying screw 35 is rotatably engaged with the limit support frame 351, which is fixedly connected to the other end of the slide rail 11. The output end of the electric push rod 22 is fixedly connected to the push plate 221, which is located directly below the lower mold 21. Several limit blocks 313 are evenly arranged on both sides of the groove 312, and the several limit blocks 313 are fixedly connected to the top surface of the mounting plate 31. Several slide grooves 341 are evenly opened at the lower end of the clamping support frame 34, and the several limit blocks 313 are sequentially engaged in the interior of the several slide grooves 341.

[0025] The specific settings and functions of this embodiment are described below. When it is necessary to remove the lower mold 21 from the lower mold mounting slot 2, the electric push rod 22 is activated first to push the lower mold 21 out from the lower mold mounting slot 2. Then, the first drive assembly 32 is activated, which drives the bidirectional lead screw 33 to rotate, so that one end of the clamping support frame 34 extends into the lower end of the lower mold 21. Since the lower mold 21 is rectangular, the clamping support frame 34 can stably clamp the lower mold 21. When the clamping support frame 34 moves in opposite directions, the limit block 313 will constrain the movement direction of the clamping support frame 34 to prevent it from deviating. The conveying lead screw 35 drives the clamping assembly 3 to move horizontally to the top of the lower mold storage box 4, completing the disassembly of the lower mold 21. This eliminates the need for other handling equipment in the workshop to assist in replacing the lower mold 21, reducing the manpower and material resources required for replacing the car roof mold.

[0026] Example 2

[0027] like Figure 1 and Figure 3 As shown, slide rails 11 are fixedly connected to both sides of the base plate 1, one side of the second drive assembly 36 is fixedly connected to one side of the slide rail 11, and rollers 311 are rotatably engaged at the four corners of the mounting plate 31, with the rollers 311 rotatably engaged on the inner side of the slide rail 11.

[0028] The overall effect of this embodiment is that when the lead screw 35 drives the clamping assembly 3 to move in the horizontal direction, the roller 311 slides on the slide rail 11. The slide rail 11 provides horizontal support for the entire clamping assembly 3 and reduces the friction force on the clamping assembly 3, so that the lead screw 35 can stably and smoothly transport the movement of the clamping assembly 3.

[0029] The usage and working principle of this device are as follows: When it is necessary to remove the lower mold 21 from the lower mold mounting slot 2, first activate the electric push rod 22 to push the lower mold 21 out of the lower mold mounting slot 2. Then activate the first drive assembly 32, which drives the bidirectional lead screw 33 to rotate, causing one end of the clamping support frame 34 to extend into the lower end of the lower mold 21. Since the lower mold 21 is rectangular, the clamping support frame 34 can stably clamp the lower mold 21. When the clamping support frame 34 moves in opposite directions, it limits the movement. Block 313 constrains the movement direction of the clamping support frame 34 to prevent it from deviating. The conveying screw 35 drives the clamping assembly 3 to move horizontally to directly above the lower mold storage box 4, completing the disassembly of the lower mold 21. When the conveying screw 35 drives the clamping assembly 3 to move horizontally, the roller 311 slides on the slide rail 11. The slide rail 11 provides horizontal support for the entire clamping assembly 3 and reduces the friction force on the clamping assembly 3, so that the conveying screw 35 can stably and smoothly convey the movement of the clamping assembly 3.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
