Description

Technical Field

[0001] This utility model belongs to the field of riser technology, and in particular relates to a quick-release heating and heat-insulating riser. Background Technology

[0002] Heating and insulating risers are special risers used in the casting process, made by adding a certain amount of thermite, flux, oxidant and heat insulation material during the riser manufacturing process. Their function is to compensate for the shrinkage of the casting during the casting process and avoid the formation of shrinkage cavities or porosity defects. Heating and insulating risers have become an important tool in modern casting technology by combining the dual functions of heating and heat insulation.

[0003] The heat-insulating riser disclosed in the utility model with authorization announcement number CN208288932U includes a riser body, a riser cover installed at one end of the riser body, a beveled ring installed on one side of the outer wall of the riser cover, a locking block installed on one side of the outer wall of the beveled ring, and a sliding groove opened on the beveled ring at the position of the locking block. A needle is installed on one side of the outer wall of the locking block. A slot is opened at the end of the riser body near the riser cover, and the locking block is located inside the slot. This utility model provides a locking block, a slot, a needle, an adhesive capsule, a guide hole, a sliding groove, and a slider. When installing this heat-insulating riser, the sliding groove on the outer wall of the beveled ring is aligned with the slider on the inner wall of the riser body, so that the slider slides into the sliding groove and pushes the riser cover, causing the riser cover to move closer to the riser body. During the movement of the riser cover, the locking block on the outer wall of the beveled ring gradually moves closer to the slot at one end of the riser body. However, in the application of this technical solution, after the casting is completed and the molten metal solidifies, the riser and the mold will also be fixed together. Large tools such as pneumatic hammers are required to remove the riser. There is a technical problem that the heat-generating and heat-insulating riser connected to the mold cannot be easily, quickly and safely disassembled. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a quick-release heating and heat-insulating riser, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a quick-release heating and heat-insulating riser, comprising a riser body and further comprising: a disassembly base at the bottom of the riser body, an easy-cut base at the bottom of the disassembly base, a groove on the outer side of the easy-cut base, an easy-cut groove on the inner side of the easy-cut base, connecting blocks on both sides of the top of the disassembly base, positioning slots on both sides of the bottom of the riser body, and a flow guiding component on the top of the riser body.

[0007] Furthermore, the top of the disassembly seat is inserted into the bottom end of the riser body, and the disassembly seat and the easy-cut seat are in a ring shape.

[0008] Furthermore, the easy-cut groove is annular, and the groove and the easy-cut groove are on the same horizontal plane.

[0009] Furthermore, the positioning slots are symmetrically arranged at the bottom of the riser body, and the connecting blocks are symmetrically arranged at the top of the disassembly base, with the connecting blocks embedded inside the positioning slots.

[0010] Furthermore, the flow guiding assembly includes a gathering guide, which is disposed on the top of the riser body. A stabilizing outer sleeve is disposed on the outer side of the bottom of the gathering guide, and a stabilizing inner sleeve is disposed on the inner side of the bottom of the gathering guide.

[0011] Furthermore, the stabilizing outer sleeve is nested on the top of the outer side of the riser body, and the stabilizing inner sleeve is inserted into the top of the inner side of the riser body.

[0012] This utility model has the following beneficial effects:

[0013] This invention features a disassembly assembly at the bottom of the riser body. When using the heating and insulating riser, the disassembly base is first inserted into the bottom of the riser body, and the connecting clip is simultaneously inserted into the positioning slots on both sides of the bottom of the riser body. This allows the easy-cutting base to be positioned and installed at the bottom of the riser body. During casting, one end of the riser body with the easy-cutting base is placed above the location of the casting that needs to be fed or next to the hot spot where the casting will eventually solidify. After the casting is completed, the heating and insulating riser can be easily and quickly removed by striking the weak points formed by the grooves and easy-cutting lines on the outer and inner sides of the easy-cutting base, which are at the same level, without damaging the casting body. This makes the process more operable.

[0014] This invention features a flow guiding component at the top of the riser body. When molten metal needs to be added to the mold through the heating and insulation riser, the converging guide is connected to the top of the riser body. Simultaneously, a stabilizing outer sleeve and a stabilizing inner sleeve at the bottom of the converging guide are respectively fitted onto the top of the inner and outer sides of the riser body to stabilize the converging guide and prevent it from tilting and falling when adding molten metal. This achieves the effect of conveniently and safely adding molten metal to the mold through the converging guide to ensure the casting quality. Attached Figure Description

[0023] Please see Figure 1-4 As shown, this utility model is a quick-release heating and heat-insulating riser, including a riser body 1, and further including: a ring-shaped disassembly seat 2 provided at the bottom end of the riser body 1, the top of the disassembly seat 2 being inserted into the bottom end of the riser body 1, a ring-shaped easy-cut seat 3 provided at the bottom of the disassembly seat 2, positioning grooves 8 provided on both sides of the bottom of the riser body 1, the positioning grooves 8 being symmetrically arranged at the bottom of the riser body 1, and connecting blocks 10 provided on both sides of the top of the disassembly seat 2, the connecting blocks 10 being symmetrically arranged at the top of the disassembly seat 2, the connecting blocks 10 being embedded into the inner side of the positioning grooves 8, and the disassembly seat 2 being inserted into the riser body 1. At the bottom of the interior, the connecting block 10 is simultaneously engaged with the positioning slots 8 set on both sides of the bottom of the riser body 1. This achieves the purpose of positioning and installing the easy-cut seat 3 at the bottom of the riser body 1. The outer side of the easy-cut seat 3 is provided with a groove 4, and the inner side of the easy-cut seat 3 is provided with an annular easy-cut groove 9. The groove 4 and the easy-cut groove 9 are on the same horizontal plane. After the casting is poured, the heat-generating and heat-insulating riser can be easily and quickly removed by striking the weak parts formed by the groove 4 and the easy-cut groove 9 on the outer and inner sides of the easy-cut seat 3, which are at the same horizontal position, without damaging the casting body, thus making it more operable.

[0024] When using a heat-generating and heat-insulating riser, first insert the disassembly seat 2 into the bottom of the riser body 1, and at the same time, insert the connecting clip 10 into the positioning slots 8 set on both sides of the bottom of the riser body 1. The easy-cut seat 3 can then be positioned and installed at the bottom of the riser body 1. When casting, place one end of the riser body 1 with the easy-cut seat 3 above the position where the casting needs to be fed or next to the hot node where it will finally solidify. After the casting is completed, the heat-generating and heat-insulating riser can be easily and quickly removed by hitting the weak parts formed by the grooves 4 and the easy-cut grooves 9 set on the outer and inner sides of the easy-cut seat 3 at the same level.

[0025] As a further implementation of this embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, a flow guiding component is provided on the top of the riser body 1. The flow guiding component includes a gathering guide 6, which is located on the top of the riser body 1. A stabilizing outer sleeve 5 is provided on the outer side of the bottom of the gathering guide 6. The stabilizing outer sleeve 5 is nested on the top of the outer side of the riser body 1. A stabilizing inner sleeve 7 is provided on the inner side of the bottom of the gathering guide 6. The stabilizing inner sleeve 7 is inserted into the top of the inner side of the riser body 1. By fitting the stabilizing outer sleeve 5 and the stabilizing inner sleeve 7 onto the top of the inner and outer sides of the riser body 1 respectively, the gathering guide 6 can be stably installed on the top of the riser body 1. This achieves the effect of conveniently and safely replenishing molten metal into the mold through the gathering guide 6 to ensure the casting quality.

[0026] When it is necessary to replenish molten metal into the mold through the heating and heat-insulating riser, the gathering guide 6 is connected to the top of the riser body 1. At the same time, the stabilizing outer sleeve 5 and stabilizing inner sleeve 7 set at the bottom of the gathering guide 6 are respectively fitted onto the top of the inner and outer sides of the riser body 1 to stabilize the gathering guide 6 and prevent the gathering guide 6 from tilting and falling when replenishing molten metal.

[0027] Working principle: When using the heating and insulating riser, first insert the disassembly seat 2 into the bottom of the riser body 1, and simultaneously insert the connecting clip 10 into the positioning slots 8 set on both sides of the bottom of the riser body 1. This will position the easy-cut seat 3 at the bottom of the riser body 1. When casting, place one end of the riser body 1 with the easy-cut seat 3 above the position where the casting needs to be fed or next to the hot spot where it will finally solidify. During casting, the riser body 1 extends the cooling time of the molten metal, improves the feeding efficiency, and reduces metal loss. Furthermore, it provides heating and insulation. When replenishing molten metal into the mold, the gathering guide 6 is connected to the top of the riser body 1. At the same time, the stabilizing outer sleeve 5 and stabilizing inner sleeve 7 set at the bottom of the gathering guide 6 are respectively fitted onto the top of the inner and outer sides of the riser body 1 to stabilize the gathering guide 6 and prevent it from tilting and falling when replenishing molten metal. Then, molten metal can be replenished into the mold through the gathering guide 6. After the casting is completed, the heat-generating and heat-insulating riser can be easily and quickly removed by hitting the weak parts formed by the groove 4 and the easy-cut groove 9 set at the same horizontal position on the outer and inner sides of the easy-cut seat 3.

[0028] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
