The utility model discloses a head embedded sleeve mould, including first sleeve mould and second sleeve mould, first sleeve mould includes first mould cover, first mould core, and second sleeve mould includes second mould cover, second mould core, the first mould core of first sleeve mould is sleeved in the second mould core of second sleeve mould, the first mould cover of first sleeve mould is sleeved in the second mould cover of second sleeve mould, between the guide material cone of first mould core and the guide material cone of second mould core, between the guide material cone hole of first mould cover and the guide material cone hole of second mould cover respectively form smooth guide material cone transition surface and cone hole transition surface, and form melt channel between guide material cone transition surface and cone hole transition surface. Adopt this scheme, can choose sleeve mould specification according to the extrusion specification, do not involve the dismounting problem of complex head in the specification switching process, only need to dismount embedded sleeve mould in the specification switching process. The head nested sleeve mould with the structure can effectively save the head switching time, can improve production efficiency greatly, saves production cost.

The utility model discloses a filter bag that has the step-by-step filtration function relates to filter bag technical field, including fixed subassembly, filter subassembly and cleaning subassembly, fixed subassembly includes fixed cage frame and double-end stud, double-end stud is movably installed in fixed cage frame, filter subassembly is fixed in fixed subassembly, the cleaning subassembly is fixed in the fixed cage frame, the cleaning subassembly is fixed in the fixed cage frame, the filter subassembly is fixed in the fixed cage frame, the cleaning subassembly is fixed in the fixed cage frame, and the cleaning subassembly is fixed in the fixed cage frame. The filter assembly comprises a fixing frame, a first filter bag and a second filter bag, the first filter bag and the second filter bag are both fixedly installed in the fixing frame, the cleaning assembly is arranged in the fixing assembly and comprises a vibration piece, and the vibration piece is fixedly installed outside the fixing frame. The vibration piece is arranged on the upper surface of the filter screen, when air enters the fixed cage frame, the air firstly impacts the vibration piece to enable the vibration piece to vibrate, the contact pins on the vibration piece are in contact with the surface of the filter screen to enable the filter screen to shake, and dust is prevented from being attached to the surface of the filter screen to affect the smoothness of follow-up air circulation and the filtering effect.

The utility model discloses an oil slinging structure at the near pressure end of a supercharger, which comprises a turbine shaft (1), the near pressure end of the turbine shaft (1) is sleeved with a shaft sealing sleeve (2) and a floating bearing (3), the shaft sealing sleeve (2) and the floating bearing (3) are arranged along the axial direction of the turbine shaft (1), the outer layer of the shaft sealing sleeve (2) is sleeved with an air sealing plate (4), the outer layer of the floating bearing (3) is sleeved with a middle body (5), and the middle body (5) is sleeved with a sealing ring (6). An oil throwing cavity (6) is formed in the connecting position of the air sealing plate (4) and the middle body (5), and the lower end of the oil throwing cavity (6) is connected with an oil return pipeline (7). The utility model provides an oil throwing structure at a near-pressure end of a supercharger, which can reduce oil leakage and reduce engine oil supply frequency by reducing the design of an oil baffle plate.

A waste collection system and control method for a stamping production line, belonging to the field of press technology, is disclosed. The waste collection system includes a movable worktable. Upper hoppers are fixedly installed on the front and rear sides of the movable worktable. Below each upper hopper, a middle hopper and a lower hopper are sequentially arranged, all fixedly mounted on the base of the press. When the movable worktable is located in the die area, the upper, middle, and lower hoppers on the same side are sequentially connected for guiding and conveying waste. The upper opening of the upper hopper is lower than the table surface of the movable worktable, and the upper opening of the middle hopper is lower than the bottom of the movable worktable. When the movable worktable is working, the cooperation of the upper, middle, and lower hoppers can collect and guide waste, avoiding waste splashing. No additional waste collector is required, reducing operating costs, and the system does not affect the opening and closing of the movable worktable for die changing.
