Compared with the prior art, the utility model has the advantages that:

1. the setting element is provided with protruding edge, the stilt, place wheel hub on the stilt, the stilt is equipped with the opening simultaneously, can produce certain thermal energy at the heating process because of the mould, it can let the stilt when the inflation to set up open-ended aim at, there is the space of extension, protruding edge is provided with the face of splining, the lower mould is provided with and the face assorted portion of splining that splines, can prevent that the setting element from producing the rotation, thereby realize wheel hub's accurate positioning, and set up and used the setting element evenly to arrange a plurality of mobilizable sliders as rotation center, make the rubber coating process simple, guarantee the steady quality.

2. The positioning piece is provided with a through hole and a groove, the groove is provided with a slidable ejector block, the groove and the through hole play a certain guiding role, the smooth movement of the ejector block matched with the positioning piece can be ensured,

3. the lower die is provided with a sliding groove matched with the sliding block, a part of the sliding groove is provided with a limiting block, the sliding block can be prevented from being separated from the lower die under the condition that the sliding block deviates from the positioning piece to move when the rubber coating die is demolded, and the other part of the sliding groove is provided with a limiting surface to ensure that the sliding block moves in a certain range, so that the die assembly or the die opening of the rubber coating die is smooth.

4. The slider is provided with pressure spring and wear-resisting piece, the pressure spring helps the slider when deviating from the setting element and removing, it is smooth and easy to make its activity, go up mould and lower mould when the compound die, it can contact the slider earlier to go up the mould, and produce the friction, if go up the mould and when whole slider surface contact, it is long-lasting, must lead to the fact the whole surface wearing and tearing of slider, thereby need to change whole slider, cause cost increase like this, if set up wear-resisting piece on the slider surface, will reduce the friction of mould and slider effectively, the time is of a specified duration, if there is wearing and tearing, we only need to change wear-resisting piece can, and need not to change whole slider, thereby reduce cost.
