In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a small part injection mold that can loose core automatically, includes mould body, part and mechanism of loosing core, the mechanism of loosing core includes that the first of four non-axis motions is loosed core and the second of two axis motions is loosed core, and the first circumference evenly distributed of loosing core along the part of loosing core with the second.

Preferably, the first loose core and the second loose core respectively comprise a sliding block, a fixed die inclination guide block and a sliding block insert pin.

Preferably, the fixed die inclination guide block drives the sliding block to move, and the sliding block insert pin moves along with the sliding block.

Preferably, the number of the slider inserts is one or more.

Preferably, the number of the slider inserts is three.

Preferably, six holes are formed in the part corresponding to the side faces of the first loose core and the second loose core.

Preferably, the slider insert penetrates through the die body and is inserted into a hole in the side surface of the part.

Compared with the prior art, the beneficial effects of the utility model are as follows:

this technical scheme can accomplish a plurality of angles of finding small parts and loose core, need not carry out secondary later stage processing, and the mould can realize that the part production of loosing core of multi-angle side is once accomplished to produce in succession, improve production efficiency, reduce manufacturing cost, solved prior art and carried out the difficulty of loosing core of a plurality of angles on finding small parts, lead to machining efficiency low, problem that manufacturing cost is high.
