Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples.

As shown in fig. 1 to 6, the detachable mold for gel injection molding comprises an outer frame 1 and an inner frame 2 detachably assembled in the outer frame 1, wherein the inner frame 2 is made of a material easy to be separated from a gel blank, and a cavity surrounded by the inner frame 2 is used for filling slurry.

For the convenience of disassembly, the inner frame 2 and the outer frame 1 of the present embodiment are inserted and assembled. The inner frame 2 comprises at least two first frame plates 21 arranged along the width direction of the outer frame 1 and second frame plates 22 correspondingly arranged along the length direction of the outer frame 1, at least two first slots 11 for the first frame plates 21 to be inserted are arranged on the outer frame 1, the second frame plates 22 are arranged between two adjacent first frame plates 21, one side, close to the outer frame 1, of each second frame plate 22 is provided with an inserting block 221, and the outer frame 1 is provided with corresponding second slots 12. In this embodiment, three first slots 11 are arranged along the length direction of the outer frame 1, and a user inserts two of the first slots 11 as required and uses the second frame plate 22 with a corresponding length in a matching manner, so that blanks with different sizes can be prepared; in addition, a plurality of first frame plates 21 can be inserted and correspondingly matched with a plurality of second frame plates 22 to prepare a plurality of blanks at one time.

In order to prevent the second frame plate 22 from coming off in the width direction of the outer frame 1, the insertion block 221 has an outer cross section gradually enlarged from one side of the second frame plate 22 toward the outside.
