[0020] In order to enable the above-mentioned purpose, features and advantages of the utility model to be more clearly understood, the utility model will be further described below in combination with the drawings and embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0021] 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.

[0022] Example 1

[0023] like Figures 1-4 As shown, this utility model provides an automotive mold with an automatic replacement function, including a support frame 1, a stamping mechanism 2, a fixed seat 3, and a lower mold 4. The fixed seat 3 is equipped with a fixing mechanism 7, which includes a fixed shaft 71, two sets of rollers 75, and two sets of springs 76. A rotating plate 72 is rotatably connected to the outer wall of the fixed shaft 71, and a rotating plate 73 is rotatably connected to the outer wall of the fixed shaft 71. Rotating seats 74 are fixedly installed on the top of both rotating plates 72 and 73. The stamping mechanism 2 is located on the top of the support frame 1. The two sides of the fixed seat 3 are fixedly installed on one side of the support frame 1. The bottom of the lower mold 4 is slidably connected to the top of the fixed seat 3. The fixed shaft 71 is fixedly installed inside the fixed seat 3. One end of the rotating plate 73 is located on the outer wall of the rotating plate 72. The two sets of rollers 75 are movably arranged inside the two sets of rotating seats 74. One end of each set of springs 76 is fixedly connected to one side of the two sets of rotating seats 74, and the other end of each set of springs 76 is fixedly connected to the top of the fixed seat 3.

[0024] The specific settings and functions of this embodiment are described below. As the mold is used more times, wear, deformation, or cracks will appear on the mold surface. When the lower mold 4 needs to be replaced, the lower mold 4 is inserted from one side of the fixed base 3, so that the lower mold 4 slides along the fixed base 3 to one end. When the two sides of the lower mold 4 contact the outer walls of the two sets of rollers 75, they squeeze the two sets of rollers 75 to both sides, thereby driving the two sets of rotating seats 74 to move to both ends. The two sets of rotating seats 74 drive the rotating plate 1 72 and rotating plate 2 73 to rotate around the fixed shaft 71. The two sets of rotating seats 74 squeeze the two sets of springs 76 respectively. During the movement of the lower mold 4, the rollers 75 will rotate inside the rotating seats 74 until the lower mold 4 is installed in the appropriate position. The springs 76 provide the opposite force, so that the two sets of rollers 75 fix the lower mold 4. By setting the fixing mechanism 7, the fixing mechanism 7 can ensure that the lower mold 4 maintains a stable position during operation, which is convenient for operators to unload the old mold and install the new mold. The replacement operation is simple and easy, which reduces the downtime of the production line, improves production efficiency, and speeds up the production pace.

[0025] Example 2

[0026] like Figures 1-3As shown, one side of the fixed seat 3 is fixedly provided with a speed reducer motor 5, the output end of the speed reducer motor 5 is drivingly connected with a screw rod 6, the screw rod 6 is arranged in the interior of the fixed seat 3, and the outer wall of the screw rod 6 is in threaded connection with the interior of the lower mold 4.

[0027] The effect achieved by the whole embodiment is that when the lower mold 4 is automatically replaced, the speed reducer motor 5 is a bidirectional motor, the speed reducer motor 5 is started to drive the screw rod 6 to rotate, the lower mold 4 can only move horizontally due to the limiting of the fixed seat 3, and then the screw rod 6 drives the lower mold 4 to move in the interior of the fixed seat 3 in the process of rotation, when the lower mold 4 needs to be installed, the screw rod 6 is rotated to drive the lower mold 4 to slide into the interior of the fixed seat 3, when replacement is needed, the speed reducer motor 5 is reversely rotated to drive the screw rod 6 to separate the lower mold 4 from the interior of the fixed seat 3, thereby realizing automatic replacement of the lower mold 4, making the replacement of the lower mold 4 more convenient and easy to operate, and improving the efficiency of replacement of the lower mold 4.

[0028] The working principle and method of using the device are as follows: as the number of uses of the mold increases, the surface of the mold will be worn, deformed or cracked, when the lower mold 4 needs to be replaced, the lower mold 4 is inserted from one side of the fixed seat 3, the speed reducer motor 5 is a bidirectional motor, the speed reducer motor 5 is started to drive the screw rod 6 to rotate, the lower mold 4 can only move horizontally due to the limiting of the fixed seat 3, and then the screw rod 6 drives the lower mold 4 to move in the interior of the fixed seat 3 in the process of rotation, the lower mold 4 slides along the fixed seat 3 to one end, when the two sides of the lower mold 4 contact the outer walls of the two groups of rollers 75, the two groups of rollers 75 are extruded to two sides, thereby driving the two groups of rotating seats 74 to move to two ends, the two groups of rotating seats 74 drive the rotating plate one 72 and the rotating plate two 73 to rotate around the fixed shaft 71, the two groups of rotating seats 74 extrude the two groups of springs 76, in the process of movement of the lower mold 4, the rollers 75 rotate in the interiors of the rotating seats 74, until the lower mold 4 is installed to a proper position, the springs 76 provide opposite forces to fix the two groups of rollers 75 to the lower mold 4, when replacement is needed, the speed reducer motor 5 is reversely rotated to drive the screw rod 6 to separate the lower mold 4 from the interior of the fixed seat 3, thereby realizing automatic replacement of the lower mold 4.

[0029] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms, any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical scheme of the present application.
