Description

Technical Field

[0001] The present invention relates to the field of casting, and in particular to an installation structure of a riser exothermic agent and an installation method thereof. Background Art

[0002] The main function of the exothermic agent used in casting is to reduce or eliminate the heat loss from the top surface of the riser due to radiation and convection. Its mechanism of action is manifested in two aspects: heat preservation and shrinkage compensation.

[0003] When applied to the surface of molten metal, casting exothermic agents burn and release a large amount of heat. Simultaneously, the exothermic agent rapidly expands, forming a porous, highly insulating layer that isolates the riser metal from air, preventing convection and radiation heat transfer, reducing heat loss, and resulting in a slower solidification rate for the riser metal. Improper use of exothermic agents can reduce the riser's shrinkage feeding effectiveness.

[0004] Therefore, it is necessary to provide a new installation structure and installation method of a riser exothermic agent to solve the above technical problems. Summary of the Invention

An adjusting rod 1 is provided on each side of the connecting head 9, and one end of the adjusting rod 1 is fixed inside the connecting head 9. The outer side of the other end of the adjusting rod 1 is fixedly connected to the movable sleeve 6, and the support rod 7 is slidably connected inside the movable sleeve 6. The hook 13 is fixedly connected to the inside of the connecting head 9, and one end of the hook 13 is set in a pointed cone shape.

[0037] It should be noted that the stability of the cloth bag during the casting process is ensured by the hanging bracket.

[0038] See also Figures 1 to 5, a positioning piece 8 is provided above the groove 4 of the riser 5, and a pressing plate 12 is symmetrically fixedly connected to the bottom of the positioning piece 8. The pressing plate 12 is slidably plugged into the groove 4. The internal thread of the positioning piece 8 is connected to the extrusion column 11. The bottom end of the extrusion column 11 is an arc-shaped surface and is arranged between the pressing plates 12. The top of the extrusion column 11 is fixedly connected to the knob 10;

[0039] It should be noted that: the support rod 7 is squeezed by the pressing plate 12, and then the squeezing column 11 is lowered by turning the knob 10, so that its end squeezes the pressing plate 12 and disperses from each other, so that the pressing plate 12 is fixed in the groove 4, thereby further improving the connection strength between the support rod 7 and the groove 4;

[0040] See also Figures 1 to 5 The embodiment of the present invention also provides a method for installing a riser exothermic agent, and the specific steps are as follows:

[0041] S1: Select the length of the hanging bracket, the size of the cloth 3 and the dosage of the heating agent 2 according to the specifications of the riser 5;

[0042] S2: Wrap the heating agent 2 with cloth 3 to form a cloth bag;

[0043] S3: Pierce the hook 13 through the cloth bag;

[0044] S4: Grind grooves 4 at both ends of the diameter direction above the riser 5;

[0045] S5: Fix the ends of the two support rods 7 of the suspension bracket into the grooves 4 on both sides respectively, so that the cloth bag is stably installed on the riser 5;

[0046] See also Figures 1 to 5 , the cloth bag is set at the upper center of the riser 5, and the heating agent 2 is arranged at the riser 5 to achieve the best shrinkage feeding effect;

[0047] See also Figures 1 to 5 , the end of the support rod 7 is fixed in the groove 4 by welding, riveting or mechanical locking to ensure the stability of the support rod 7 during the casting process;

[0048] See also Figures 1 to 5 When fixing the support rod 7, you can first insert the pressing plate 12, use the pressing plate 12 to squeeze the support rod 7, and then turn the knob 10 to lower the squeezing column 11, so that its end squeezes the pressing plate 12 to disperse each other, and fix the pressing plate 12 in the groove 4 to further improve the connection strength between the support rod 7 and the groove 4.

[0049] The working principle of the riser exothermic agent installation structure and installation method provided by the present invention is as follows: a cloth bag 3 wrapped with the exothermic agent 2 is fixed in the grooves 4 at both ends of the diameter direction above the riser 5 by a hanging bracket. The cloth 3 effectively prevents the exothermic agent 2 from scattering. At the same time, the exothermic agent 2 releases heat during the casting process, raising the temperature of the riser 5 and extending its shrinkage feeding time, thereby optimizing the quality of the casting. The hanging bracket ensures the stability of the cloth bag during the casting process, improving the reliability of the entire installation structure.

[0050] The length of the suspension bracket can be adjusted by dragging the movable sleeve 6 to slide on the outside of the support rod 7 and adjusting the overlapping length between the support rod 7 and the adjustment rod 1, so as to adjust the total length of the suspension bracket according to different specifications of the riser 5;

[0051] After the end of the support rod 7 is inserted into the groove 4, the pressing plate 12 can be inserted, and the pressing plate 12 can be used to squeeze the support rod 7. Then, by turning the knob 10, the squeezing column 11 is lowered, so that its end squeezes the pressing plate 12 to disperse each other, and the pressing plate 12 is fixed in the groove 4 to further improve the connection strength between the support rod 7 and the groove 4.
