Description

Technical Field

[0001] This utility model relates to the field of static pressure molding, and in particular to a riser anti-detachment device for static pressure molding. Background Technology

[0002] A riser, also known as a cap, is a supplementary part added to the top or side of a casting to prevent defects. In the process of hydrostatic casting, the cavity of the riser is a cavity that stores liquid metal. It replenishes metal during casting and has the functions of preventing shrinkage cavities, porosity, venting, and slag accumulation. The main function of the riser is to feed the casting.

[0003] During the casting process, risers are installed on top of or to the side of the casting, usually through threaded connections. When the product is removed after casting, it may collide with the riser, causing it to shake and rotate, resulting in loosening and affecting its stability, thus hindering its normal operation.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-3 The above describes a riser detachment prevention device for hydrostatic molding, comprising a base 1, a mounting ring 2, a mounting mechanism 3, and a pressing mechanism 4. Multiple screws are slidably inserted and connected to the base 1 to install and fix the base 1 and the mounting ring 2. The bottom end of the mounting ring 2 is fixedly connected to the upper surface of the base 1. The mounting ring 2 is used to install the riser, the mounting mechanism 3, and the pressing mechanism 4. The mounting mechanism 3 is disposed on the mounting ring 2 and forms a fixing structure on the mounting ring 2 to install and fix the riser. The pressing mechanism 4 is disposed on the mounting ring 2 and forms a pressing structure on the mounting ring 2 to limit and fix the mounting mechanism 3. The pressing mechanism 4 compresses and limits the riser, improving its stability and preventing detachment.

[0030] Furthermore, the mounting mechanism 3 includes a fixed ring 31, a mounting groove 32, an extrusion block 33, and a movable rod 34. The outer wall of the fixed ring 31 is fixedly connected to the bottom of the inner wall of the mounting ring 2. The inner wall of the fixed ring 31 has an internal thread. The fixed ring 31 is used to install a riser. The bottom of the riser slides into the inner cavity of the fixed ring 31. The bottom of the outer wall of the riser has an external thread. By rotating the riser, its bottom is threadedly connected to the inner wall of the fixed ring 31. The mounting groove 32 is arranged in a ring array at equal intervals on the top of the mounting ring 2. The mounting groove 32 is used to install and accommodate the extrusion block 33. The extrusion block 33 is arranged in a ring array at equal intervals on the top of the inner wall of the mounting ring 2. The extrusion block 33 slides into the inner cavity of the mounting groove 32. Multiple extrusion blocks 33 are moved toward the center of the mounting ring 2, so that the outer wall of the extrusion block 33 fits against the outer wall of the riser, thus extruding and fixing the riser and improving its stability. One end of the movable rod 34 is fixedly connected to one side of the outer wall of the extrusion block 33, and the other end of the movable rod 34 is slidably inserted into the mounting ring 2. The other end of the movable rod 34 is set in a hemispherical shape. The movable rod 34 drives the extrusion block 33 to move in the horizontal direction. By sliding the bottom of the riser into the inner cavity of the mounting ring 2, the riser is rotated, so that the bottom of the riser is rotatably connected to the inner wall of the fixed ring 31, thus installing the riser. Then, the movable rod 34 is moved again, driving multiple extrusion blocks 33 to move toward the center of the mounting ring 2, extruding and fixing the outer wall of the riser and improving its stability.

[0031] Furthermore, the extrusion mechanism 4 includes a movable ring 41, extrusion grooves 42, a fixed rod 43, and bolts 44. The inner cavity of the movable ring 41 is slidably inserted into the top of the mounting ring 2. The movable ring 41 is positioned above the movable rod 34, and its inner wall is in contact with the outer wall of the mounting ring 2. The movable ring 41 moves vertically on the mounting ring 2 to move multiple movable rods 34 together. The extrusion grooves 42 are arranged in a circular array at equal intervals at the bottom of the inner wall of the movable ring 41. The inner cavity of the extrusion grooves 42 is slidably inserted into the other end of the movable rod 34. As the movable ring 41 moves vertically downward, the inner wall of the extrusion grooves 42 extrudes the fixed rod 43, causing the multiple movable rods 34 to move together with the extrusion block 33. The bottom end of the fixed rod 43 is fixedly connected to the upper surface of the base 1, and the top of the fixed rod 43 is slidably inserted into the movable ring 41. The connecting rods 43 are arranged in a ring array to install the movable ring 41, allowing the movable ring 41 to move stably in the vertical direction along the fixed rods 43. The bottom of the bolt 44 is rotatably connected to the upper surface of the base 1, and the top of the bolt 44 is threadedly connected to the movable ring 41. By rotating the bolt 44, the movable ring 41 is moved vertically. By rotating the bolt 44, the movable ring 41 is moved stably in the vertical direction along the fixed rod 43. The movable ring 41 moves downward at the top of the mounting ring 2, causing the inner wall of the extrusion groove 42 to extrude the fixed rod 43. The multiple movable rods 34 drive the extrusion block 33 to move together. The extrusion block 33 is arranged in an L-shape, with the top of the extrusion block 33 being inclined. The top of the inner wall of the extrusion groove 42 is also inclined, and the inner wall of the extrusion groove 42 is in contact with the other end of the movable rod 34.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
