Description of the Invention: [Technical Field to Which the Invention Is Alonged] The present invention relates to a bicycle seat cushion, and particularly refers to a method of manufacturing a bicycle seat cushion. [Prior Art] The most direct contact between the bicyclist and the bicycle is a bicycle seat in addition to the grip. The bicycle seat cushion can be generally divided into hard and soft seat cushions, and the hard seat is often used for competitive racing bicycles. Soft seat cushions are often used in the daily bicycles of the general public. In order to make the bicycle ride more comfortable, many bicycle seat cushions are designed to meet the human body and prevent sports injuries. For example, a conventional bicycle seat cushion manufacturing method mainly applies the outer cover layer of the seat cushion to the inner wall of the mold cavity by vacuum suction, and then divides the miscellaneous materials of two different materials into the cavity, thereby making the outer portion An inner layer and a foam layer are successively stacked on the inner surface of the coating, and then the inner shell of the cushion is combined with the outer layer and the foam layer to complete the bicycle. The bicycle body cushion structure comprises an inner shell, the inner shell is provided with a foam layer, the outer layer is disposed on the inner shell and is covered with a foam layer, and the intermediate layer is disposed on the foam layer and the outer cover. between. When the knight is sitting on the above bicycle seat cushion, the knight's isch bone can be bombarded with the middle layer and the hair/(10), which not only can bear the knight, but also allows the knight to have a more comfortable ride. In the above-mentioned conventional bicycle seat tamping method, due to the outer covering, it is pulled by the vacuum force correction (4) in the cavity (4), so that the comfortable feeling layer structure of the outer cover will be stretched unevenly with the shape of the cavity (4) . If there is a deep training in the right hole (4), the thickness of the coating will be thinner and the strength will be weaker. (4) The surface will also produce unevenness and poor finished shape. Furthermore, since the elastic material is directly poured into the cavity of the mold, after the elastic material flows in the cavity, the interposer will exhibit an uneven thickness distribution in the seat, and the knight is seated in the intermediary. The thinner portion of the layer is likely to cause partial dissection. Therefore, the main purpose of the present invention is to provide a method for manufacturing a bicycle seat, which can have a more uniform and better surface. Finished product shape. &_ Method Another object of the present invention is to provide a bicycle seat cushion which can be made with a relatively uniform thickness of the bicycle seat cushion, so that the rider has a more comfortable ride. In order to achieve the above object, the bicycle seat cushion provided by the present invention is mainly made of a -first mold and a second mold, and the method firstly provides an outer cover layer on a base of the first mold and the like. Between the impurities, the colloid is then applied to the hollow portion of the forming frame for the outer covering to have an i-th layer from a seat cushion. Then, the outer cover layer is moved away from the first mold 'and completely covered with one of the mold holes of the second mold, and then the outer cover layer is attached to the inner wall of the mold cavity by air suction, and then injected The foaming material is bonded to the first elastic layer 1646375 in the "cavity hole", and a second elastic layer is formed in the cavity, and finally the upper mold is closed to the lower mold, The inner cover of the seat cushion is combined with the outer cover layer and the second elastic layer.
