This utility model discloses a lubricating oil receiving device for injection molding machine mold clamping, including an injection molding machine mold clamping body and a machine upper shell located below the injection molding machine mold clamping body. The injection molding machine mold clamping body has a moving platen in the middle. The machine upper shell is provided with an upper shell panel, which includes a fixed mold stop panel, an integrated oil guide plate, an integrated oil receiving platen, and a rear platen oil stop platen. A moving platen oil receiving platen is provided below the moving platen. The fixed mold stop panel, the integrated oil guide plate, the integrated oil receiving platen, and the rear platen oil stop platen are connected sequentially. The fixed mold stop panel and the integrated oil guide plate are inclined downwards and connected to the integrated oil receiving platen, and the rear platen oil stop platen is inclined downwards and connected to the integrated oil receiving platen. This utility model adopts a plate bending method, integrating multiple parts into one part through the process of bending steel plates, reducing full welding and grinding, improving production efficiency, and achieving the purpose of rapid spot welding installation.

The application discloses a cutting synergist for liquefied petroleum gas and a preparation method thereof, and belongs to the technical field of cutting synergists. The cutting synergist is prepared by mixing the following components with the mass content: an alkyl ferrocene mixture 5-8%, n-octane 6-10%, ethylene glycol monoethyl ether 8-10%, isooctyl nitrate 10-15%, acetone 15-25%, and 200# solvent oil 25-45%. The application is a high-efficiency energy-saving synergist for cutting liquefied petroleum gas, and the performance of the liquefied petroleum gas after the addition of the synergist can reach and exceed the cutting performance level of the original petroleum gas and acetylene gas, and the liquefied petroleum gas can completely replace acetylene gas, natural gas and pure propane to be used as industrial gas for metal cutting. The product performance exceeds that of natural gas, industrial propane and the same kind of synergists on the market, and has a wide application prospect, and is a great breakthrough of industrial gas in the industrial field of China.

The application discloses a steel pipe surface polishing device, which belongs to the technical field of handheld polishers. The steel pipe surface polishing device comprises a polisher, a fixing frame, a polishing mechanism and a longitudinal handle which are sequentially arranged on the polisher. The polisher is provided with a power output end which penetrates through the fixing frame. The polishing mechanism comprises two rotating wheels which are distributed left and right. The rotating wheel close to the fixing frame is connected with the power output end. The two rotating wheels are connected with polishing belts. The fixing frame is fixedly provided with a fixing frame. The fixing frame is slidably provided with a sliding frame. The other rotating wheel is mounted on the sliding frame. The lower end of the sliding frame is provided with a working cavity. The working cavity is provided with a fixed position fixing rotating drum and a sliding sliding rotating drum. The fixing rotating drum and the sliding rotating drum can rotate in the working cavity. The steel pipe surface polishing device has the beneficial effects that the circumferential wrapping angle of the sand belt to the steel pipe can be increased, the number of circumferential rotation is reduced, the polishing efficiency and effect are improved, the operation is simple, and the steel pipe surface polishing device is convenient to use.
