Novel mold cover plate

Abstract

The utility model is suitable for the technical field of tunnel concrete segment prefabrication, and provides a novel mold cover plate which comprises a cover plate and further comprises a pressing lug fixedly arranged on the cover plate and used in cooperation with a clamp, and the cover plate is fixed to a mold. One end of the spring is limited on the mold, the other end of the spring is limited on the cover plate, and the cover plate is rotationally connected with the mold. After the mold is closed, the cover plate can be easily closed on the mold due to the reaction of the elastic force of the spring, and the closing can be completed by pressing the pressing lug by using the clamp. And when the mold needs to be opened, the cover plate can automatically bounce under the elastic force action of the spring only by loosening the clamp. According to the novel mold cover plate, the number of cover plate pressing lugs is reduced, and the operation efficiency of workers can be improved; compared with an original mold, cover plate supporting legs are reduced, and therefore the operation space of workers is enlarged; as the cover plate can be easily closed and bounced, the production efficiency is greatly improved; and by simplifying the design and optimizing the operation process, the cost is reduced.

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0020] like Figure 1-3 As shown, a new mold cover plate provided by an embodiment of the present invention includes a cover plate and further includes:

[0021] The pressing ear 1 is fixedly provided on the cover plate and is used to fix the cover plate on the mold by cooperating with the clamp to prevent the cover plate from being accidentally opened during the processing;

[0022] Spring 2, one end of the spring 2 is limited on the mold, and the other end of the spring 2 is limited on the cover plate, and the cover plate is rotatably connected to the mold.

[0023] In this embodiment of the utility model, after the mold is closed, the cover plate is closed. Due to the elastic force of spring 2, the cover plate can be easily closed on the mold. At this time, the clamp is used to press the pressing lug 1 to complete the closing. When the mold needs to be opened, simply release the clamp, and the cover plate will automatically spring up under the elastic force of spring 2, thus quickly opening the mold.

[0024] The new mold cover reduces the number of cover pressing ears 1, which can improve the worker's operating efficiency; compared with the original mold, the cover legs are reduced, thereby increasing the worker's operating space; because the cover can be easily closed and popped up, production efficiency is greatly improved; by simplifying the design and optimizing the operating process, costs are reduced.

[0025] like Figure 1 and Figure 2As shown in FIG. 1 , as a preferred embodiment of the present invention, a limit seat 1 4 is fixedly connected to the mold, and one end of the spring 2 is limited in the limit seat 1 4. The limit seat 1 4 limits one end of the spring 2, ensuring that the spring 2 can correctly apply elastic force when the mold is closed.

[0026] like Figure 1-3 As shown in FIG. 1 , as a preferred embodiment of the present invention, the cover is fixedly connected to a second limit seat 5, and the other end of the spring 2 is limited in the second limit seat 5. The second limit seat 5 limits the other end of the spring 2 and cooperates with the first limit seat 4 to ensure the stability of the spring 2 when the cover is opened and closed.

[0027] like Figure 1 and Figure 2 As shown in FIG. 1 , as a preferred embodiment of the present invention, the cover plate is fixedly connected to a cover plate shaft 3, which is rotatably connected to the mold. The arrangement of the cover plate shaft 3 allows the cover plate to rotate relative to the mold to achieve an opening and closing action.

[0028] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, a spring support tube 6 is sleeved and fixedly connected to the cover shaft 3, and the spring 2 is installed on the spring support tube 6. The spring support tube 6 further stabilizes the position of the spring 2 and improves the stability of the overall structure.

[0029] like Figure 1 As shown in FIG. 1 , as a preferred embodiment of the present invention, handles 7 are fixedly connected to both sides of the cover plate to facilitate workers to open or close the cover plate.

[0030] The working principle of this utility model is:

[0031] With this new mold cover, once the mold is closed, the cover is easily secured to the mold thanks to the elastic force of spring 2. At this point, the cover is tightened by pressing lug 1 with a clamp. To open the mold, simply release the clamp, and the cover automatically springs up under the elastic force of spring 2, allowing the mold to open quickly.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
