The above object of the present invention is achieved by the following technical means.

The die carrier comprises a fixed die holder, a movable die holder is movably mounted on the fixed die holder, a die cavity is formed in the middle of the fixed die holder, a fine plate is movably mounted in the die cavity, a plurality of groups of positioning holes are formed in the fine plate and correspond to a plurality of groups of positioning pins movably mounted in the die cavity, the fine plate can be movably placed in the die cavity, and the positioning pins can be inserted into the corresponding positioning holes.

Preferably, the positioning pins are in a circular truncated cone structure, the top of any one positioning pin is provided with an air hole, and the diameter of the air hole is within the range of 0.1mm-0.15 mm.

Specifically, fixing pins for fixing the mounting position of the fine plate are fixedly mounted at four corners of the molding cavity, and the height of each fixing pin is smaller than that of each positioning pin.

Furthermore, the diameter of the positioning pins and the positioning holes in the same group is the same, and the diameter of the positioning pins and the positioning holes in different groups is different.

Furthermore, 5 groups of positioning pins and positioning holes are arranged, namely, the group A-A ', the group B-B ', the group C-C ', the group D-D ' and the group E-E '.

The utility model discloses a seted up polymorphic type locating hole on same smart board, the detachable locating pin of the internal portion of synthetic die cavity of deuterogamying is selected the locating pin and the locating hole of the same type according to the demand, can directly carry out the processing technology switching of different grade type on with the die carrier, and the suitability is stronger, has reduced the processing cost.
