Description

Technical Field

[0001] The utility model relates to the technical field of risers, in particular to a thermal insulation riser. Background Art

[0002] Riser refers to the supplementary part added on the top or side of the casting to avoid defects in the casting. In the casting mold, the cavity of the riser is a cavity for storing liquid metal. It replenishes metal when the casting is formed, and has the functions of preventing shrinkage, shrinkage, exhaust and slag collection. The main function of the riser is to compensate for shrinkage. The design function of the riser is different. The form, size and opening position of the riser are different.

[0003] The top of the common riser adopts a flat-end design, and in order to reduce the waste of solution heat source, the inner diameter of the top flat end of the riser is small. Therefore, when pouring the solution, the solution will spill and cause great waste. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a thermal insulation riser to solve the problems mentioned in the above background.

[0005] The utility model provides the following technical solution: comprising: a riser top and a riser bottom,

[0006] Also includes,

[0007] The guide part is fixed on the inner wall of the riser top, and the top of the riser top is provided with a top edge part.

[0008] The baffle portion is fixedly arranged at the upper end portion of the top edge portion.

[0009] Furthermore, a bottom surfacing edge is fixedly arranged on the inner wall of the bottom of the riser, and the upper part of the bottom surfacing edge adopts a slope structure.

[0010] Furthermore, the inner diameter of the bottom of the riser is greater than the inner diameter of the top of the riser.

[0011] Furthermore, the guide portion is spiral-shaped, and the upper and lower portions of the guide portion are both slope structures.

[0012] Furthermore, the baffle portion adopts an arc-shaped structure, and the width of the baffle portion is smaller than the wall thickness of the top edge portion.

[0013] Furthermore, the top of the top edge portion is covered with a cover plate portion.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The top of the present application adopts a flat mouth design with a larger inner diameter, and a spiral guide portion is arranged inside the top of the riser, and the surface of the guide portion also adopts a downward slope structure. Therefore, when the solution is poured into the flat mouth inside the top of the riser, the solution can enter along the spiral channel of the guide portion, reducing splashing and spilling, while reducing the heat loss of the solution and making the solution flow faster.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3, including: a riser top 1 and a riser bottom 2, the riser top 1 and the riser bottom 2 are fixed, and the riser top 1 and the riser bottom 2 are connected through channels, the outer diameter and the inner diameter of the riser bottom 2 are both larger than the inner diameter and the outer diameter of the riser top 1, the solution inside the riser top 1 enters the casting cavity along the riser bottom 2, the guide part 4 is fixedly arranged on the inner wall of the riser top 1, and a top edge part 5 is arranged on the top of the riser top 1, the guide part 4 is spirally shaped on the cavity inner wall of the riser top 1, and the upper and lower parts of the guide part 4 are both slope structures, through the design of the spiral structure, when the cavity inside the riser top 1 is at the position of the guide part 4, the inner diameter is reduced, which can reduce heat loss to a certain extent, and at the same time, the guide part 4 with a spiral structure can also make the solution flow faster through the guide part 4 to the riser bottom 2, and the design of the slope structure makes the solution move more smoothly, and the baffle part 6 is fixedly arranged on the upper end of the top edge 5. The inner wall of the riser bottom 2 is fixed with a bottom edge 3, and the upper part of the bottom edge 3 adopts a slope structure, so that the solution flowing into the cavity of the riser bottom 2 can flow into the casting cavity faster. When pouring the solution, it is generally designed to pour the solution along the upper side of the riser top 1 to the top of the riser top 1, and the slope design of the top edge 5 makes one side of the top of the riser top 1 higher and the other side lower. The solution is poured into the riser top 1 along the lower position. The higher top edge 5 can reduce the situation of solution spilling, and the larger top edge 5 opening and the baffle 6 can also reduce the situation of solution spilling. The baffle 6 adopts an arc structure, and the width of the baffle 6 is less than the wall thickness of the top edge 5. The cover plate 7 can also be placed at the opening of the top edge 5, so that the lower position of the cover plate 7 is against the inner side of the arc groove of the baffle 6, thereby closing the opening of the top edge 5, which has a strong thermal insulation effect.

[0022] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
