Stated further, the exhaust passage penetrates through the movable mold, and the exhaust passage is connected with the exhaust hole in a penetrating manner.
Stated further, the vent is in communication with the vacuum.
Further elaborating, the water-cooling channels are all arranged in the inner part close to one side of the inner wall of the fixed die in an embedded mode.
Further elaborating, the extension of cover half is equipped with the sealing washer, the surface of lock pin with the inner wall of slot closely laminates.
Stated further, the shaping blocks are arranged in the middle of the fixed die, and the inserting cores are distributed in an annular array mode around the central axis of the movable die.
Compared with the prior art, the utility model has the beneficial effects that:
wheel hub's cooling is comparatively even, and wheel hub's the place that differs in thickness also can dispel the heat fully, adopts the assembling die to go on, and the recess that can press from both sides is being reserved to the cover half when the drawing of patterns, and is more convenient during the drawing of patterns, and the quality and the life of product improve.
