Description

Technical Field

[0001] The utility model belongs to the technical field of precision casting, and in particular relates to a locking hook for a silica sol precision casting mold shell. Background Art

[0002] Precision casting is the general term for the process of obtaining castings with precise dimensions. Precision casting is also called lost wax casting. Its products are precise and complex, close to the final shape of the parts, and can be used directly without or with little processing. Silica sol has good bonding ability and filling performance. The mold shell made of it has the characteristics of high strength, high gloss, and easy demoulding, so it has been widely used in this field.

[0003] Since the silica sol mold shell has a certain dryness requirement, it needs to be hung up with a hook for ventilation and drying after production and molding. When the hook is connected to the silica sol mold shell, a locking structure is often installed on the hook to fix the silica sol mold shell. However, although the existing silica sol mold shell locking hook can also firmly lock the silica sol mold shell, the operation is not convenient enough, and it is not convenient to quickly complete the locking and loosening of the silica sol mold shell. In view of this, the present utility model is specially proposed. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a locking hook for a silica sol precision casting mold shell that can overcome the above problems or at least partially solve the above problems.

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a silica sol precision casting mold shell locking hook, including a hook body, and also including: a threaded column, fixedly connected to the lower end of the hook body; a limit pressure plate, threadedly connected to the upper end of the threaded column; a rotating disk, rotatably connected to the lower end of the threaded column; a mounting block, equidistantly distributed in a circle outside the threaded column; an adjusting rod, symmetrically rotatably connected to the upper and lower ends of the mounting block, and the ends of the two adjusting rods away from the mounting block are respectively rotatably connected to the limit pressure plate and the rotating disk; a locking plate, rotatably connected to the side of the mounting block away from the threaded column.

[0006] In order to facilitate the locking plate to stably move outward when the rotating disk approaches the limiting pressure plate, further, a circle of trapezoidal ring is fixedly connected to the threaded column.

[0007] In order to prevent the locking plate from damaging the silica sol mold shell, further, arc chamfers are provided at both upper and lower ends of the locking plate away from the threaded column.

[0008] In order to facilitate the staff to better limit and fix the limit pressure plate, further, two fixing sleeves are symmetrically fixedly connected to the upper surface of the limit pressure plate.

[0009] In order to facilitate flexible adjustment of the length of the hook body, the hook body further includes a connecting rod, a hook body and a threaded rod, the connecting rod is fixedly connected to the threaded column, a threaded groove is provided in the connecting rod, the hook body is fixedly connected to the threaded rod, and the threaded rod is threadedly connected in the threaded groove.

[0010] In order to facilitate the hook body to be stably hung on the bracket, further, the end of the hook body away from the connecting rod is fixedly connected with a deformable metal rod.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the utility model uses a limiting pressure plate, a rotating disk, a mounting block, an adjusting rod, a locking plate, a threaded column and a trapezoidal ring and other components in coordination. By rotating the threaded column, the silica sol mold shell can be quickly locked on the hook body, and by setting a plurality of locking plates, the silica sol mold shell can be locked more firmly. When the silica sol mold shell needs to be removed from the hook body, the silica sol mold shell can be quickly removed from the hook body by rotating the threaded column in the opposite direction. Compared with the traditional locking hook, the locking hook can complete the locking and loosening of the silica sol mold shell more quickly, effectively improving the efficiency of the production and manufacturing of the silica sol mold shell.

[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 4 A silica sol precision casting mold shell locking hook includes a hook body 6, and also includes: a threaded column 5, fixedly connected to the lower end of the hook body 6; a limiting pressure plate 1, threadedly connected to the upper part of the threaded column 5; a rotating disk 2, rotatably connected to the lower end of the threaded column 5; a mounting block 3, circumferentially and equidistantly distributed on the outer side of the threaded column 5; an adjusting rod 301, symmetrically rotatably connected to the upper and lower ends of the mounting block 3, and the ends of the two adjusting rods 301 away from the mounting block 3 are rotatably connected to the limiting pressure plate 1 and the rotating disk 2 respectively; a locking plate 4, rotatably connected to the side of the mounting block 3 away from the threaded column 5.

[0022] A trapezoidal ring 501 is fixedly connected to the threaded column 5 .

[0023] When the silica sol mold shell needs to be hung on the bracket to dry after production and keep it fully dry, the locking hook can be taken to the side of the silica sol mold shell, and then the threaded column 5 can be inserted into the mold opening of the silica sol mold shell, and the limiting pressure plate 1 can be made close to the mold opening of the silica sol mold shell. Then the staff can use one hand to limit and fix the limiting pressure plate 1, and use the other hand to rotate the threaded column 5 through the hook body 6, and then the threaded column 5 will move upward under the action of the thread, and then the threaded column 5 will drive the rotating disk 2 and the trapezoidal ring 501 to move upward together. As the rotating disk 2 continues to move upward, the mounting block 3 will move outward under the action of the adjusting rod 301 and the trapezoidal ring 501, and then the locking plate 4 will be on the mounting block 3, moves outward until it is tightly attached to the inner wall of the silica sol mold shell die opening, so that the silica sol mold shell can be firmly connected with the locking structure. Finally, the staff can hang the silica sol mold shell on the bracket through the hook body 6 to dry. When the silica sol mold shell is dry, the silica sol mold shell can be removed from the bracket through the hook body 6, and then the limiting pressure plate 1 can be limited and fixed again, and the threaded column 5 is rotated in the opposite direction. The threaded column 5 will drive the rotating disk 2 to move away from the limiting pressure plate 1, and then the limiting pressure plate 1 and the rotating disk 2 will drive the locking plate 4 to separate from the inner wall of the silica sol mold shell die opening through the adjusting rod 301 and the mounting block 3, so that the silica sol mold shell can be separated from the locking hook and put into precision casting.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 4 , a silica sol precision casting mold shell locking hook, is basically the same as Example 1, and further: the upper and lower ends of the locking plate 4 away from the threaded column 5 are provided with arc chamfers. Through the setting of the arc chamfers, when the locking plate 4 contacts the inner wall of the silica sol mold shell mold opening, the locking plate 4 can avoid scratching the inner wall of the silica sol mold shell mold opening, thereby effectively improving the protection effect of the silica sol mold shell.

[0026] Two fixing sleeves 101 are symmetrically fixedly connected to the upper surface of the limiting pressure plate 1. Through the setting of the fixing sleeves 101, when it is necessary to rotate the threaded column 5 to move the locking plate 4 outward so that it is in contact with the inner wall of the mold shell, the staff can insert their fingers into the fixing sleeves 101 to limit and fix the limiting pressure plate 1, so that the threaded column 5 can be rotated through the hook body 6 so that the rotating disk 2 can move smoothly upward.

[0027] The hook body 6 includes a connecting rod 601, a hook body 602 and a threaded rod 603. The connecting rod 601 is fixedly connected to the threaded column 5. A threaded groove is provided in the connecting rod 601. The hook body 602 is fixedly connected to the threaded rod 603. The threaded rod 603 is threadedly connected in the threaded groove. By forming the hook body 6 consisting of the connecting rod 601, the hook body 602 and the threaded rod 603, the length of the hook body 6 can be flexibly changed according to the size of the silica sol mold shell during use, so that the staff can better move the silica sol mold shell by locking the hook, providing convenience for the staff.

[0028] The end of the hook body 602 away from the connecting rod 601 is fixedly connected with a deformable metal rod 604. Through the setting of the metal rod 604, when the produced silica sol mold shell is hung on the bracket for drying through the locking hook, the metal rod 604 can be bent, so that the hook body 602 can be hung on the bracket more firmly, avoiding the locking hook from falling from the bracket, causing the silica sol mold shell to fall to the ground and break.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
