The distribution design of the invention reduces the height of thedie head, shortens the length of the runner, improves the cooling efficiency, ensures more convenient operation of the film pulling, reduces the amount of polymer accumulated in the die head, and leads the changing of the material or the color more rapid.

The invention discloses a compact pressure self-compensation total-sea-depth stop valve, and belongs to the relevant technical field of valve bodies. The compact pressure self-compensation total-sea-depth stop valve comprises two stop valve bodies which are oppositely arranged on the same valve body and are of the same structure. Each stop valve body comprises a stop valve screw plug assembly, a valve element assembly, an isolation pressure sheet assembly, a valve sleeve, a stop valve spring and a valve seat. The stop valve bodies are opened in a manner of being hydraulically driven, and therefore remote control can be achieved. Closing of the stop valve bodies is achieved through the force of the stop valve springs and hydraulic force generated by the area difference between the two sidesof the large end of the valve element assembly. The form of ceramic and stainless steel cooperation is adopted in cooperation between the valve element assembly and other parts, friction force in themotion process of the valve element assembly is effectively reduced, and meanwhile the possibility of jamming of the valve element assembly is reduced. The two oppositely-arranged stop valve bodies use the same valve seat in common, and the space utilization rate is increased. According to the compact pressure self-compensation total-sea-depth stop valve, the structure is simplified, the size isreduced, and then the complexity and cost of a buoyancy adjusting system of a submersible are reduced.

A five-way valve integrated channel module is fixedly connected to the lower surface of a storage device of a storage medium, a five-way valve is arranged in the middle of the five-way valve integrated channel module, one connector of the five-way valve communicates with the storage device, and the other connector of the five-way valve communicates with the storage device. The other two pairs of connectors used for forming the two independent circulation loops are connected with integrated channels constructed in the five-way valve integrated channel module respectively, and the integrated channels extend to the side faces to be communicated with the hose connectors. According to the automobile heat management five-way valve body assembly, the runner driving pump, the runner switching driving motor, the runner switching valve element and other parts are integrated, a large number of pipelines and auxiliary parts (fasteners, hoops, ribbons, supports and the like) in a conventional heat management system are simplified, the weight is reduced on the whole, the runner length is shortened, and the cost is reduced. The energy utilization rate and the raw material utilization rate are improved.

The invention relates to the field of unmanned aerial vehicle design, in particular to an unmanned aerial vehicle with a night cruise mode and a lamp holder thereof. The technical problems that one side of a movable mold core has more oblique side core pulling requirements, the structure size of a mold is certainly increased if more oil cylinder driving mechanisms are adopted, the using requirements for an injection molding machine are increased, and the mold cost is sharply increased are solved in the mode that a mold frame structure adopts a two-plate-mold two-time mold opening mode.
