Disclosed is a continuous casting and continuous forging forming process for an aluminum wheel. The process combines the advantage of low-pressure filling stability of molten aluminum alloy, and utilizes the strengthening effect of extrusion deformation forging of a mold locking ring and a pressure module to improve the mechanical properties of an aluminum wheel material to close to the forging level. A mold cavity is sealed by means of the mold locking ring and a mold locking taper, and the extrusion forging pressure acts on the surface of the aluminum alloy in the closed cavity, so that the requirement of equipment for mold closing tonnage is lowered, and the cost of the equipment is far lower than that of forging equipment and equivalent to that of casting equipment.

The application discloses a suction disc structure with small pressing force, which comprises a suction disc, wherein the suction disc comprises a back plate and a glue body, the glue body is tightly combined with one side of the back plate, the other side of the back plate is provided with a connecting part, the back plate is made of hard material, the glue body is made of soft material, the back plate comprises an inner ring part and an outer ring part, the outer ring part is arranged around the inner ring part, the curvature of the inner ring part is X, the curvature of the outer ring part is Y, and Y>X. The glue body is tightly combined with one side of the back plate, the hard back plate can assist the soft glue body in adsorption, and the adsorption effect can be improved; the inner ring part of the back plate is arranged relatively gently, i.e. approximately in a flat plate shape, while the outer ring part is arranged relatively curvedly; when the back plate is pressed, force is applied to the middle part of the inner ring part; the inner ring part can easily deform, the required force can be reduced, the glue body bears force better, and the adsorption effect of the suction disc can be improved under the premise of reducing the pressing force.

This application provides a thermal insulation foam, a method for preparing the thermal insulation foam, and a refrigeration device. The thermal insulation foam has a honeycomb structure with multiple honeycomb pores penetrating the foam along a first direction parallel to the centerline of the honeycomb pores. The density of the thermal insulation foam decreases along a second direction perpendicular to the first direction. This allows for the simultaneous optimization of low density and high compressive strength in the thermal insulation foam.

The present invention addresses the problem of providing a depth filter which has excellent filtration accuracy with respect to a fluid that contains fine particles and coarse particles and has a wide particle size distribution, and which has high liquid permeability, while maintaining a low filtration pressure, thereby being capable of performing filtration at a high flow rate. The present invention provides a depth filter which is formed by rolling a fiber assembly into a cylinder, the fiber assembly being formed of melt blown fibers which are formed of a thermoplastic resin A and melt blown fibers which are formed of a thermoplastic resin B that has a lower melting point than the thermoplastic resin A. This depth filter has a gradient where the average fiber diameter of the melt blown fibers which are formed of the thermoplastic resin A and the average fiber diameter of the melt blown fibers which are formed of the thermoplastic resin B continuously decrease from the outer circumference toward the inner circumference of the cylinder of the depth filter; and the average fiber diameters of the melt blown fibers which are formed of the thermoplastic resin A and the melt blown fibers which are formed of the thermoplastic resin B are decreased from the range of 20 µm to 1 µm to the range of 0.99 µm to 0.1 µm.
