Detailed Description

The utility model will be further described with reference to examples and drawings, to which reference is made, but which are not intended to limit the scope of the utility model.

As shown in fig. 1-5, the dovetail-shaped mosaic structure of a shell provided by the utility model comprises a die and an insert body 2, wherein the insert body 2 is detachably arranged in the die, the insert body 2 consists of a mounting part 201, an inserting part 202, a limiting part 203 and a blocking part 204, the upper end of the mounting part 201 is fixedly connected with the inserting part 202, the side end of the mounting part 201 is fixedly connected with the limiting part 203, one end of the limiting part 203 far away from the mounting part 201 is fixedly connected with the blocking part 204, and the blocking part 204 is positioned at the lower end of the limiting part 203.

Specifically, the installation portion 201 can install the insert body 2 in the mold, and simultaneously under the cooperation of the blocking portion 204, the purpose of positioning can be achieved, so that the insert body 2 is prevented from being separated from the mold, and the limiting portion 203 is used for preventing the insert body 2 from shaking after being installed in the mold, so that the stability of the insert body 2 is improved.
