Stamping is a pressure processing method that applies pressure to materials by using a die installed on a press at room temperature to cause separation or plastic deformation, so as to obtain the required parts. An automobile ceiling generally refers to the decorative interior parts of an automobile roof, which is usually realized by a molding process. A single-function automobile ceiling can no longer meet the requirements of consumers, and more and more functions need to be integrated on the ceiling. Therefore, more abundant requirements are put forward in the production. Thus, a positioning structure of an automobile ceiling mold is particularly needed.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.
[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a positioning structure for an automobile ceiling mold, including an upper mold 1, a limiting mechanism 2 is arranged on one side of the surface of the upper mold 1, a lower mold 3 is installed on the other side of the surface of the upper mold 1, and a buffering mechanism 4 is arranged on one side of the surface of the lower mold 3;
[0019] The limiting mechanism 2 includes a square groove 201, a connecting block 202, a cylinder 203, a connecting column 204, a limiting box 205, a limiting clip 206 and a sliding groove 207. A square groove 201 is opened on one side of the surface of the upper mold 1. A connecting block 202 is connected inside the square groove 201. One end of the connecting block 202 is connected to a cylinder 203. A connecting column 204 is connected inside the cylinder 203. A limiting box 205 is sleeved on the surface of the cylinder 203. A limiting clip 206 is connected to the surface of the connecting column 204. A sliding groove 207 is opened inside the limiting box 205. When the upper mold 1 and the lower mold 3 perform automobile ceiling pressing, one side of the two is attached. At this time, the cylinder 203 is embedded inside the limiting box 205, and both ends of the limiting clip 206 on the connecting column 204 slide into the limiting box 205 from one end of the limiting box 205 and finally are embedded into the sliding groove 207. At this time, the limiting clip 206 connects the cylinder 203 and the limiting box 205, which can play a fixing role in the pressing of the upper mold 1 and the lower mold 3. When the upper mold 1 and the lower mold 3 are separated, the limiting clip 206 can slide out of the sliding groove 207. At this time, the cylinder 203 is separated from the limiting box 205.
[0020] Further, the square groove 201 is fitted with the limiting box 205, and the cylinder 203 and the limiting box 205 form a mutually sliding relationship. Through the setting of the limiting box 205, when the upper mold 1 and the lower mold 3 are attached, the upper mold 1 drives the cylinder 203 to be embedded inside the limiting box 205. At this time, the limiting clip 206 can slide into the sliding groove 207 inside the limiting box 205, and then the cylinder 203 and the limiting box 205 can be fixed.
[0021] Further, the limiting box 205 is connected to the lower mold 3, and both ends of the limiting clip 206 penetrate through the cylinder 203 and are fitted with the sliding groove 207. Through the setting of the limiting clip 206, when the limiting clip 206 slides into the limiting box 205 and is fitted with the sliding groove 207, the cylinder 203 and the limiting box 205 can be fixed, improving the stability of the mutual cooperation between the upper mold 1 and the lower mold 3.
[0022] Furthermore, the buffer mechanism 4 includes a circular groove 401, a spring 402, a limit block 403 and a buffer pad 404. A circular groove 401 is formed on one side of the surface of the lower die 3. The spring 402 is connected inside the circular groove 401. One end of the spring 402 is connected to the limit block 403, and one end of the limit block 403 is connected to the buffer pad 404. Through the arrangement of the circular groove 401, the spring 402, the limit block 403 and the buffer pad 404, when the upper die 1 and the lower die 3 perform the pressing of the automobile roof, one side of the two is in contact. At this time, the upper die 1 presses the buffer pad 404, and the buffer pad 404 applies a force to the spring 402. The spring 402 is compressed and applies a force to the upper die 1, so as to appropriately buffer the contact between the upper die 1 and the lower die 3. The limit block 403 can prevent the spring 402 from detaching from the circular groove 401.
[0023] Furthermore, the lower die 3 is connected to the spring 402, and four groups of springs 402 are provided. Through the arrangement of the springs 402, when the upper die 1 presses the buffer pad 404, the springs 402 can be compressed simultaneously. At this time, the springs 402 apply a reverse force to the upper die 1, so as to appropriately buffer the contact between the upper die 1 and the lower die 3.
[0024] Working principle: When the upper die 1 and the lower die 3 perform the pressing of the automobile roof, one side of the two is in contact. At this time, the cylinder 203 is embedded inside the limit box 205, and both ends of the limit clip 206 on the connecting column 204 slide into the limit box 205 from one end of the limit box 205 and finally are embedded in the sliding groove 207. At this time, the limit clip 206 connects the cylinder 203 with the limit box 205, which can play a fixing role in the pressing of the upper die 1 and the lower die 3. When the upper die 1 and the lower die 3 are separated, the limit clip 206 can slide out of the sliding groove 207. At this time, the cylinder 203 is separated from the limit box 205. When the upper die 1 and the lower die 3 are in contact, the upper die 1 presses the buffer pad 404, and the buffer pad 404 applies a force to the spring 402. At this time, the spring 402 is compressed and applies a force to the upper die 1, so as to appropriately buffer the contact between the upper die 1 and the lower die 3. The limit block 403 can prevent the spring 402 from detaching from the circular groove 401.
[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
