Description

Technical Field

[0001] The utility model relates to the technical field of automobile spare tire cover plate processing, in particular to an automobile spare tire cover plate processing die. Background Art

[0002] Car tires are one of the main components that enable a car to run normally. Since tires may be damaged due to accidents during driving, drivers generally have several spare tires. The spare tires are protected by covers, and the covers are processed with molds during the production process.

[0003] At present, most of the spare tire cover processing molds on the market have a U-shaped base plate that can move up and down in the mold, so that the molded spare tire cover can be pushed out of the mold, making it convenient for users to remove the molded spare tire cover. For example, a spare tire cover processing mold disclosed in Chinese patent publication No. CN213082190U, however, after the molded spare tire cover is pushed out of the mold through the U-shaped base plate, the spare tire cover often gets stuck in the U-shaped base plate, which makes it difficult for users to remove the cover. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. For example, at present, most of the automobile spare tire cover processing molds on the market have a U-shaped base plate that can move up and down in the mold, so that the molded automobile spare tire cover can be pushed out of the mold, thereby making it convenient for the user to remove the molded automobile spare tire cover. However, after the molded automobile spare tire cover is pushed out of the mold through the U-shaped base plate, the automobile spare tire cover is often stuck in the U-shaped base plate, which makes it still troublesome for the user to remove the part. Therefore, a automobile spare tire cover processing mold is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The cam face of the cam face is fixedly connected to the top of the cam face, and the cam face is fixedly connected to the top of the cam face, and the cam face is fixedly connected to the top of the cam face.

[0007] Preferably, the telescopic bracket includes a hollow block, the upper surface of the hollow block is fixedly connected to the bottom of the horizontal base plate, the bottom of the hollow block contacts the inner wall of the mold cavity, the inner wall of the hollow block is fixedly connected to a first spring, the left and right ends of the first spring and the side of the vertical base plate are fixedly connected to a sliding column, the surface of the sliding column is fitted with a first sliding sleeve, and the upper surface of the first sliding sleeve is fixedly connected to the bottom of the horizontal base plate.

Then, the horizontal plate 111 is placed between the two vertical base plates 6, and the positioning column 114 is in contact with the positioning groove 9. Then, the second sliding sleeve 82 is moved to the lowest position through the electric push rod 83, and the hemispherical block 3 is staggered with the first groove 7. Then, the vertical base plate 6 is brought into contact with the horizontal base plate 5 through the hemispherical block 3, and the positioning groove 9, the positioning column 114 and the limit block 10 are moved. In coordination, the horizontal plate 111 is fixed on the bottom mold 1, and then the injection liquid is injected into the mold cavity 2 through the liquid inlet pipe 112. After the injection is completed, the liquid inlet pipe 112 is closed through the sealing cover 113. After the injection liquid is cooled and formed, the spare tire cover for automobiles can be obtained. When taking out the molded spare tire cover for automobiles, first raise the second slide sleeve 82 to the highest point through the electric push rod 83, and move the molded spare tire cover for automobiles out of the mold cavity 2. At the same time, when the vertical base plate 6 moves to the highest point, the hemispherical block 3 is aligned with the first groove 7, and the vertical base plate 6 is separated from the horizontal base plate 5 by the thrust of the first spring 42 on the slide column 43. At this time, the user removes the sealing top plate 11 and the spare tire cover for automobiles from between the two vertical base plates 6 in turn.
