The utility model relates to the technical field of interior trimming dies, and discloses an automobile interior trimming die convenient for rapid cooling, the left side of the top of an upper die is fixedly connected with a feed pipe, the right side of the top of the upper die is fixedly connected with an overflow pipe, a sealing mechanism is arranged in a lower die and the upper die, and a cooling mechanism is arranged on the outer side of the lower die. The sealing mechanism comprises a sealing assembly and a fixing assembly, the sealing assembly is arranged between the lower mold and the upper mold, and the fixing assembly is arranged in the top of the upper mold. According to the automobile interior mold convenient to rapidly cool, by arranging the cooling mechanism, water enters the liquid storage frame through the liquid inlet pipe and then is discharged through the liquid discharging pipe, flowing water directly overflows the lower mold and the upper mold to cool finished products in the lower mold and the upper mold, the cold water flow is large, and the cooling effect is better; and the heat exchange speed between water in the liquid storage frame and the lower mold is increased through the arrangement of the fixed fin plates and the open holes, and the cooling efficiency is improved.

The invention discloses a machining device with a built-in fixture with a masking film and an end face reciprocating motion and an application method thereof. The machining device is composed of a machining cavity, an electromechanical mechanism, a liquid container, a mechanism and a pipeline, wherein the machining cavity is internally provided with the fixture with the masking film and is provided with at least one end face plate capable of reciprocating motion; the electromechanical mechanism drives the push-pull end face plate to reciprocate; and a sensing and control member. The processing cavity is a frame body capable of being opened and closed and is composed of two paired sub frame bodies. One end face of each sub-frame body is an inner end face; the inner end faces of the two sub-frame bodies are the same in shape or matched in a concave-convex mode, are attached together along the common surface and seal liquid when combined. A pattern selective transparent film and a pattern selective shielding film are fixed on the inner end surface of the sub-frame body at high tension; after the film is fixed by the sub-frame bodies, the surface of the film extending out of the frame body and not attached to the inner end surface is used as a clamping surface of the clamp. According to the processing device, the liquid processing efficiency and quality can be improved; the size of processing equipment is reduced, and the quantity demand of liquid is reduced.

The invention relates to the technical field of gas turbines, in particular to an exhaust structure of a gas turbine, which comprises an exhaust chamber arranged on a gas turbine body, and the exhaust chamber is provided with a plurality of slots; the heat conduction unit comprises an upper guide block arranged at an opening in the outer side of the open groove and a lower guide block arranged at an opening in the inner side of the open groove, and is used for increasing the heat exchange surface area of the exhaust chamber; the telescopic mechanism is arranged between the upper guide block and the lower guide block and used for supporting the heat conduction unit to be limited in the open groove; the fixing mechanism is arranged on the outer wall of the exhaust chamber and used for fixing the heat conduction unit. The device can assist in reducing the temperature of the outer wall face of the gas turbine, and stable operation of the gas turbine is guaranteed; a telescopic mechanism is arranged, so that the single heat conduction unit can be conveniently mounted, dismounted and replaced; and through the arrangement of the fixing mechanism, the operation is simpler, more convenient and quicker when the heat conduction unit is replaced, and the maintenance cost is reduced.

This utility model provides a ventilation structure for a box-type substation enclosure cover, relating to the technical field of enclosure cover ventilation structures. It includes: a first plug-in fixing frame, with a filter structure on top of the first plug-in fixing frame, and a cooling structure on top of the filter structure. In this utility model, the filter structure, cooling structure, and top plate structure are sequentially assembled, and then waterproof adhesive is applied to the connection gaps for further fixation. In hot weather, the exhaust fan is activated via remote operation of the external control equipment installed inside the box-type substation. When the exhaust fan is operating, it draws in air from inside the box-type substation and discharges it through multiple vents, increasing the airflow exchange speed and improving ventilation and heat dissipation. After prolonged use, when cleaning and maintaining the exhaust fan inside the enclosure cover ventilation structure, the filter plate is first disassembled, and then the exhaust fan and filter plate are cleaned and maintained.
