Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings for a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention by those skilled in the art.

The structure of the present invention as shown in fig. 2 to 4 is a thin suspended wall cooling system of an extrusion die, wherein the extrusion die is provided with an air groove 1 on a surface facing the thin suspended wall, the air groove 1 is connected with an air hole 3, and air is pumped through the air hole 3;

in order to solve the problems existing in the prior art and overcome the defects thereof, the invention aims to avoid the phenomenon that the thin suspended wall is bent due to insufficient cooling after the drying and shaping, and the utility model adopts the technical scheme that:

as shown in FIG. 2, the utility model discloses a thin suspended wall cooling system of extrusion tooling, extrusion tooling set up basin 2 in the thin suspended wall of orientation with set up the opposite one side of gas tank, basin 2 be connected with water hole 4.

The utility model discloses a design a water route cooling system, the direct wainscot of this thin cantilever import department sets up the water route of one section cooling usefulness, lets the section bar of here cool off rapidly in dry design import department, lets its quick design. Compared with the prior art, the invention has the following advantages:

1. the thin wall part can be cooled from two sides, so that the section can not be bent when coming out;

2. the high-temperature section which just enters the dry shaping from the die head can be rapidly cooled when meeting cold water, thereby ensuring the rapid shaping of the thin wall.

As shown in fig. 4, the water tank 2 includes two sections, i.e., a vertical water tank and an inclined water tank, which are communicated with each other; the vertical water tank is vertical to the moving direction of the cavity, and the inclined water tank and the moving direction of the cavity are obliquely arranged to form an included angle; the joint of the two sections of water tanks is arranged at the position of the extrusion die close to the cavity surface.

As shown in fig. 3 and 4, the opposite end of the vertical water tank connected with the inclined water tank is connected with a No. 1 water hole; the opposite end of the inclined water tank connected with the vertical water tank is connected with the No. 2 water hole; the No. 1 water hole is a water inlet hole, and the No. 2 water hole is a water outlet hole.

No. 1 water hole and No. 2 water hole are in the same position in the height direction, so a straight line cannot be adopted. The design like the design in fig. 4 enlarges the water cooling area, prolongs the flowing distance of the water cooling and fully exerts the cooling effect.

The utility model discloses basin 2's concrete size can adopt:

as shown in fig. 4, the distance between the No. 1 water hole and the end surface of the extrusion die is 50 mm; the projection length of the inclined water tank in the moving direction of the cavity is 140 mm.

The utility model discloses an application method:

processing an exhaust hole and an air groove on the left side of the thin wall, as shown in figure 3, exhausting air on the left side to ensure that the section bar is tightly adsorbed to the dry-shaped cavity to move; meanwhile, a waterway is processed at the position on the right side of the inlet position by 50 mm; as shown in fig. 4, the cooling water enters the water hole No. 1 as shown by the arrow, and then flows into the water hole No. 2 along the water tank milled at the right side to flow out. Therefore, when the section enters dry shaping, the right side is sufficiently cooled by water, so that the thin cantilever is rapidly shaped at the position, and the thin cantilever at the position is prevented from being bent and the tail wing is prevented from being uneven when the section goes out of the dry shaping.
