In order to achieve the purpose, the following technical scheme is provided:

the utility model provides an injection mold of slider under area can be spacing, including the hydro-cylinder mechanism of loosing core, still include the slider under can spacing, the slider includes fixed spout and slider down can spacing, fixed spout is located on the movable mould frame, the slider is located in the fixed spout, can be in the fixed spout round trip movement, the one end and the core of slider are connected, be equipped with spacing screw on the fixed spout, spacing screw is close to another tip of slider, the spacing groove has been seted up to the lower surface of slider, the tip of the one end of spacing groove dorsad core is the opening, the opening corresponds with spacing screw, the in-process that the slider removed, spacing screw removes in the spacing groove, and carry on spacingly to the slider through the spacing inslot wall, prevent its roll-off.

Furthermore, the fixed sliding groove comprises a sliding groove plate, a sliding groove fixing plate and pressing strips, the sliding groove fixing plate is fixed on two sides of the sliding groove plate, the pressing strips are arranged at the top ends of the sliding groove plates on two sides and matched with the shoulder structures of the sliding blocks, and the limiting screws are arranged on the upper surface of the sliding groove plate.

Furthermore, inclined through holes are respectively formed in the sliding block and the sliding groove plate, an inclined guide post is arranged on the fixed die frame and inserted into the inclined through holes, and the sliding block is guided to move through die opening and die closing.

Furthermore, the number of the oil cylinder core-pulling mechanisms on the injection mold is 1-3, and the number of the lower sliding blocks capable of limiting is 1-3.

Furthermore, the oil cylinder core-pulling mechanism is only arranged above the mould or above and on one side of the mould, the lower sliding block can be limited to be arranged below and on two sides of the mould or below and on one side of the mould, when the scale of the mould is large, the oil cylinder core-pulling mechanism is arranged above and on one side of the mould, the lower sliding block can be limited to be arranged on the other side below the mould, when the scale of the mould is small, the oil cylinder core-pulling mechanism can be only arranged above the mould, and the lower sliding block can be limited to be arranged below and on two sides of the mould.

The beneficial effects of the utility model reside in that:

1) The utility model adopts the position-limitable lower slide block to replace the conventional oil cylinder core-pulling mechanism, thereby effectively improving the die-changing efficiency;

2) The utility model adopts the mode that the oil cylinder core-pulling mechanism is replaced by the lower limiting sliding block at least below the mould, thereby reducing the whole floor area of the mould and lowering the production cost;

3) The utility model discloses a stop screw prevents the slider roll-off down when the mould trades the mould, and the setting of spacing groove makes the distance that the slider can the roll-off down when the same, and the size of fixed spout can be littleer.
