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 resin molding rubber mold (2) comprises a cavity (213) into which a pressurized molten thermoplastic resin is placed. The rubber mold (2) comprises a core mold (21) consisting of a rubber material and having the cavity (213) formed therein, and also comprises a base mold (22) consisting of a rubber material and having a shape for allowing the core mold (21) to be placed in the base mold. The core mold (21) is formed by combining together a pair of split molds (211) along split surfaces (212) for opening the cavity (213). The base mold (22) has a lower surface section (221) and a pair of first side surface sections (222) which are formed on both sides of the direction in which the pair of split molds (211) is combined together.

The invention belongs to the field of composite material forming, and particularly relates to a thermoplasticity composite material and surface resin plastic part integrated forming method. The methodcomprises the following steps that a, a thermoplasticity composite material insert is selected; and b, after being preheated, the insert is arranged in a die to be subjected to hot pressing and injection molding integrated forming,wherein after the die is closed for the first time and a closed cavityin the assigned size is formed, resin melt is injected into the cavity through an injection molding machine, then, the die is compressed to be completely closed, the resin melt transmits pressure to the insert to form the insert, meanwhile, under the action of the melt temperature, the resin meltmelts on the surface of the insert, and the insert and the resin plastic part form surface bonding. The thermoplasticity composite material and surface resin plastic part integrated forming method combines the advantages of hot pressing forming and injection molding compression forming, and is suitable for producing high-strength, high-size-precision and complex-structure composite material products; and due to the die pressing and injection molding compression integration character, the production efficiency can be improved, and the production period is shortened.

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.
