The invention discloses a vehicle internals, which is characterized by the following: inner decoration main body (20) of door inner decoration (10) is made up with light and conformal foaming resin base material and resin molding part (23); the reinforce spew part (30) is formed by bleeding fusion resin through one part of resin molding part (23) and then supports fast resin molding part (23) and through spew part (30) to avoid resin molding part (23) to producing sharp edge; the spew part (30) can improve forming precision.

The invention discloses a device and method for hot forming of a titanium alloy corrugated pipe through current assistance, and relates to a device and method for hot forming of a corrugated pipe. The device and method for hot forming of the titanium alloy corrugated pipe through current assistance solve the problem that an existing titanium alloy corrugated pipe is difficult to manufacture, and high in cost and low in production efficiency. According to the device, the positive pole and the negative pole of an electrode (3) tightly sleeve the upper end and the lower end of a tube blank (10), a low-voltage high-current power source (5) is connected with the positive pole and the negative pole of the electrode (3) through a wire (4), a gas cylinder (7) is connected with a gas guide pipe (11) on the tube blank (10) through a gas pipe (6), and a forming die (2) is placed on a working platform of a press machine (1). The method comprises the steps that the first step, the tube blank (10) is manufactured; the second step, die setting is conducted; the third step, device installation is conducted; the fourth step, the corrugated pipe is formed; the fifth step, discharging is conducted; the sixth step, post-processing is conducted. The device and method are used for manufacturing the titanium alloy corrugated pipe.

A disc molding die, which can uniformly cool a molding object and does not generate printing nonuniformity in a printing area of the molding object, and a molded object are provided. The disc molding die is provided with a first die plate, a first mirror-surface plate, a second die plate arranged to freely advance and retreat to and from the first die plate, a second mirror-surface plate for forming a cavity with the first mirror-surface plate in a clamping state, a stamper (32), which is attached to one of the first and the second mirror-surface plates and has a fine pattern formed on its front edge plane, and a bush (55) arranged by penetrating the other of the first and the second mirror-surface plates. On a front edge plane of the above mentioned the other mirror-surface plate, the bush (55) is arranged inner than an area for forming a clamp area in a diameter direction. In this case, since an area of a front edge plane of the bush (55) becomes small, molding object cooling performance is prevented from deteriorating.
