a demoulding elastic reset mechanism 206 which leads the sliding block 204 to have the trend of returning to the demoulding position all the time is arranged between the sliding block 204 and the stripper plate 202;
the slide block 204 is always abutted against the wedge 203, and the wedge 203 and the slide block 204 form wedge matching, so that the slide block 204 is in a demoulding position when the stripper plate 202 is in a far end position, and the slide block 204 is in a mould closing position when the stripper plate 202 is in a near end position; in the embodiment, the slide block is always abutted against the wedge by utilizing the acting force of the demoulding elastic reset mechanism on the slide block;
a male die 207 is fixedly mounted on the slide block 204;
the number of the male dies 207 and the number of the female dies 103 are both two; each male die 207 corresponds to one female die 103;
each punch 207 is inserted into the die 103 corresponding to the punch position when the slide 204 is in the mold-closing position, and each punch 207 is pulled out of the die 103 corresponding to the punch position when the slide 204 is in the mold-opening position.
According to the technical scheme, the hanging punching die is adopted to process the holes on the inclined plane, so that the design of the die can be simplified, the requirement of a fine reduction process is met, and the production cost is reduced. In addition, the two male dies are fixedly arranged on the sliding block simultaneously to realize the synchronous action of the two male dies, and double holes can be punched on the workpiece in one pressing stroke of the upper die assembly, so that the use of parts can be saved, the working procedures can be saved, the production efficiency can be improved, the cost can be saved, and the processing precision of punching can be ensured.
