Open type reverse wheel production equipment

The invention relates to open type reverse wheel production equipment. Single-piece or batch casting can be carried out in a casting process of a reverse wheel, the disassembling operation can be carried out easily, the casting operation is simple and convenient and no damage to the cast reverse wheel is caused. The open type reverse wheel production equipment is made of common A3 steel; a using method comprises the steps of assembling the reverse wheels with molds one by one in a gradually increasing manner after removing the original polyurethane reverse wheel, sealing the mold with a sealing ring, and directly injecting the polyurethane material into the reverse wheel mold, thus, the finished reverse wheel can be formed once.
