Description

Technical Field

[0001] This utility model relates to the field of necking-type compensation technology, specifically a necking-type compensation structure. Background Technology

[0002] A necking feeding structure is a structure used in casting design to compensate for defects caused by volume shrinkage of molten metal during solidification. Common feeding structures include risers.

[0003] However, in the use of existing shrinkage compensation structures, when a cover is placed on top of the shrinkage compensation structure, the cover will directly rest on top of the shrinkage compensation structure. The connection between the cover and the shrinkage compensation structure is not stable enough, and the cover on top of the shrinkage compensation structure is prone to falling off. Once it falls off, it will directly affect the shrinkage compensation process and reduce the shrinkage compensation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a necked-down type shrinkage-compensating structure to solve the problem of insufficient stability in the connection between the cover and the shrinkage-compensating structure mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a necking-type compensation structure, comprising:

[0006] A riser assembly, comprising a riser body, inner rods provided on both sides of the upper inner wall of the riser body, a protrusion mounted on the upper part of the inner rods, a cap assembly provided on the upper part of the riser body, and an auxiliary assembly provided on the upper part of the cap assembly;

[0007] The lid assembly includes a lid body, with stopper plates installed on the lower two sides of the lid body. A first groove is formed on the lower two sides of the lid body corresponding to the size of the protrusion. An annular groove is formed in the middle of the inner side of the lid body corresponding to the size of the protrusion. A second groove is formed inside the lid body corresponding to the size of the protrusion.

[0008] Preferably, the auxiliary component includes a fixing rod, with a handle connected to the outer walls of both ends of the fixing rod, a magnet embedded in the middle of the side of the handle away from the fixing rod, and a protruding rod installed above the side of the handle away from the fixing rod.

[0009] Preferably, the inner rod is fixedly connected to the riser body, the protrusion is fixedly connected to the inner rod, and a groove is provided on the upper part of the riser body corresponding to the size of the stopper plate.

[0010] Preferably, the stopper plate is fixedly connected to the cover body, and the line connecting the two first grooves is perpendicular to the line connecting the second groove.

[0011] Preferably, the stopper plate is located below the second groove, the fixing rod is fixedly connected to the cover body, and the handle is rotatably connected to the fixing rod.

[0012] Preferably, a groove is provided on the upper part of the cover body corresponding to the size of the throttle, and the magnet is fixedly connected to the throttle.

[0013] Preferably, the two magnets are attracted to each other, and the protruding rod is fixedly connected to the throttle.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The necking-type shrinkage structure of this utility model can align the protrusion with the first groove by setting the cover assembly. The cover body is slowly placed downwards. After the protrusion is in the annular groove, the cover body is rotated so that the protrusion rotates 90 degrees in the annular groove. At this time, the stopper plate is above the groove of the riser body. The cover body is placed downwards and the stopper plate is inserted into the groove of the riser body. The protrusion is stuck in the second groove, which realizes the stability between the cover body and the riser body. The cover body cannot be directly lifted or rotated to open, which ensures the firmness of the cover body and avoids the cover body falling off during the shrinkage process.

[0016] (2) With the addition of auxiliary components, the necking-type shrinking structure of this utility model can be used normally by holding the protruding rod and turning the handle around the fixed rod to move the cover body. Two workers can hold the two handles respectively to move the cover body, which reduces the labor intensity and makes it convenient to move the cover body. The handle can also be stored in the cover body. Attached Figure Description

The lower two sides of the cap body 21 have first grooves 23 corresponding to the size of the protrusions 13. When the cap body 21 is lifted, the protrusions 13 cannot directly disengage from the first grooves 23 after disengaging from the second grooves 25. The inner side of the cap body 21 has an annular groove 24 corresponding to the size of the protrusions 13. The inner side of the cap body 21 has a second groove 25 corresponding to the size of the protrusions 13. When the cap body 21 is lifted, the protrusions 13 disengage from the second grooves 25, and the plug plates 22 disengage from the grooves of the riser body 11.

[0027] Furthermore, the auxiliary component 03 includes a fixing rod 31, with a handle 32 connected to the outer walls of both ends of the fixing rod 31. The handle 32 can rotate around the fixing rod 31 into the groove of the cover body 21 without occupying space. A magnet 33 is embedded in the middle of the side of the handle 32 away from the fixing rod 31. After the two magnets 33 are attracted together, the handle 32 can be placed inside the cover body 21 without occupying space. A protruding rod 34 is installed on the upper side of the side of the handle 32 away from the fixing rod 31. By holding the protruding rod 34, the handle 32 can be rotated around the fixing rod 31 out of the cover body 21.

[0028] Furthermore, the inner rod 12 is fixedly connected to the riser body 11 to ensure the stability of the inner rod 12 position.

Two operators hold the two handles 32 respectively, allowing the cover body 21 to be moved. Align the protrusion 13 with the first groove 23, and slowly lower the cover body 21. Once the protrusion 13 is in the annular groove 24, rotate the cover body 21, causing the protrusion 13 to rotate 90 degrees within the annular groove 24. At this point, the stopper plate 22 is above the groove of the riser body 11. Continue lowering the cover body 21, and the stopper plate 22 is inserted into the groove of the riser body 11. The protrusion 13 is then secured in the second groove 25, achieving stability between the cover body 21 and the riser body 11. The above is the complete working principle of this utility model.
