A chair has a chair back including a frame, two supporting legs and a bearing plate. The frame is integrated to the supporting legs in an injection molding manner. The bearing plate is integrated to a bottom frame portion and two side frame portions of the frame in the injection molding manner so that a user can lean against the bearing plate. The two side frame portions are located on two opposite sides of the bottom frame portion. The hardness of the bearing plate is lower than the hardness of the frame, and the hardness of the frame is lower than the hardness of the supporting leg. Therefore, two members whose materials are different in hardness are possibly constitute a chair back formed in one piece.

A mould with easy-replaceable mould plates comprises mould bases, and positioning units used to position mould plates on the respective mould bases. If the positioning units are removed, the mould plates can be easily replaced in such a manner that the mould plates are made to slide along the positioning units, facilitating the replacement of the mould plates. Since the mould plates can be quickly replaced, when different products are going to be produced, it only needs to redesign new mould plates with new forming blocks, and the new mould plates can also be applied to the original mould bases as long as they are formed with the guide grooves for cooperating with the positioning portions of the positioning units, greatly reducing the production cost while producing high economic benefits.

An elastic structure made by plastic injection molding comprises an elastic body and a connecting member. The elastic body includes two oppositely-connected half members which are made by plastic injection molding. The connecting member is formed around the circumference of the elastic body by injection molding and seals the two half members. While the connecting member is formed by injection molding, gas will be filled into the elastic body to make the elastic body have buffer elasticity. The half members made by plastic injection molding can be changed in shape as desired by changing the mold and can be formed with a mark portion with a brand slogan or mark during the plastic injection molding, thus making the production more convenient while controlling the yield. Furthermore, the application range of the elastic structure can be widened since the elastic structure can be made into different shapes.

A plastic formed inflation mouth structure comprises a plastic formed body which is integrally formed with an inflation mouth by plastic injection molding. The inflation mouth includes an inflation apparatus passage and a restoration unit that are integrally formed. The inflation apparatus passage unit is formed with a notch for passage of an inflation apparatus to perform the inflation or deflation. The restoration unit applies an elastic restoration force onto the notch to make the notch assuredly enclose the inflation apparatus during the inflation and ensure a high airtightness when inflation is stopped.
