Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to a modeling positioning tooling for differential pressure casting. Background Technique

[0002] During differential pressure casting, a design scheme of burying the box for modeling after 3D printing the main sand shell is often adopted. To ensure the accurate positioning of the gating system, it is necessary to accurately position the gating system (sprue) during manual bottom box modeling to ensure the concentricity of the sprue and the 3D printed sand mold sprue and ensure smooth filling. Due to the diversity of casting shapes and structural differences, sand molds of different shapes and sizes need to be designed. At the same time, due to different casting sand mold design processes, the position of the sprue will also change.

[0003] During the production process, the positioning method of the bottom box is to measure the dimensions on both sides with a steel ruler and then position the intersection points. Due to the irregular shape of the sand box and the lack of an accurate measurement reference, there will be measurement deviations in the dimensions, resulting in inaccurate positioning points of the sprue. During box closing, the position of the sand mold will shift and the concentricity of the sprue will be inconsistent. During the pouring process, misalignment and filling will occur, which is likely to cause disorder in the flow of molten aluminum. A large amount of gas and inclusions will be wrapped inside, and pores and inclusions will be generated after solidification, affecting the internal quality of the casting. Therefore, a device is needed to solve the above problems. Content of the Utility Model

Fixed seats are symmetrically welded on the outer side of the sand box. The fixed seats are connected with mounting plates through the clamping mechanism. One side of the mounting plate is telescopically connected with a support plate. A slidable adjustment block is arranged on the surface of the support plate. A scale is also arranged on the surface of the support plate. The lower surface of the adjustment block is slidably connected with a positioning plate, and a positioning hole is opened in the middle of the positioning plate.

[0006] The clamping mechanism includes a positioning groove and a positioning post. The positioning groove is opened on one side of the fixed seat, and the positioning post is detachably arranged inside the positioning groove.

[0007] Optionally, a fixing bolt is arranged on one side of the fixed seat, and the fixing bolt penetrates through the fixed seat. One end of the fixing bolt penetrating into the fixed seat is threadedly connected with the mounting plate.

[0008] Optionally, an adjusting bolt is provided on one side of the adjusting block, and a friction pad is provided on one side of the support plate to increase friction, and one end of the adjusting bolt abuts against the surface of the friction pad.

[0021] Please refer to Figures 1 to 5 , the present invention provides a technical solution: a molding positioning tooling for differential pressure casting, including a sand box 1 and a clamping mechanism. Fixed seats 7 are symmetrically welded on the outside of the sand box 1. The fixed seats 7 are connected with a mounting plate 2 through the clamping mechanism. One side of the mounting plate 2 is telescopically connected with a support plate 3. A slidable adjusting block 4 is arranged on the surface of the support plate 3. A scale 18 is also arranged on the surface of the support plate 3. The lower surface of the adjusting block 4 is slidably connected with a positioning plate 5. A positioning hole 6 is opened in the middle of the positioning plate 5;

[0022] The clamping mechanism includes a positioning groove 8 and a positioning post 9. The positioning groove 8 is opened on one side of the fixed seat 7. The positioning post 9 is detachably arranged inside the positioning groove 8.

[0023] The fixed seats 7 are arranged outside the sand box 1 during pouring. Every four form a group and are arranged in a ring with the center of the sand box 1 as the axis of symmetry. The mounting plate 2 can be inserted into the fixed seat 7. During installation, the positioning post 9 can be inserted into the positioning groove 8, and the position of the support plate 3 can be positioned so that the intersection point of the two support plates 3 coincides with the center point of the sand box 1. When the adjusting block 4 slides, the adjusting block 4 can drive the bottom positioning plate 5 to move. After the upper and lower positioning plates 5 coincide, the positioning holes 6 will intersect simultaneously. The position of the sprue can be determined through the intersecting positioning holes 6. The positioning plate 5 can slide at the bottom of the adjusting block 4, which is convenient to slide to the corresponding side according to different needs.

[0024] In this embodiment, as a preferred solution, a fixing bolt 10 is arranged on one side of the fixed seat 7, and the fixing bolt 10 penetrates through the fixed seat 7. One end of the fixing bolt 10 penetrating into the fixed seat 7 is threadedly connected with the mounting plate 2.

[0025] After the positioning post 9 is inserted into the positioning groove 8, the through hole on the mounting plate 2 is aligned with the fixing bolt 10, and the fixing bolt 10 can be threadedly engaged with the through hole on the mounting plate 2, thereby fixing the position of the mounting plate 2.

[0026] In this embodiment, as a preferred solution, an adjusting bolt 11 is provided on one side of the adjusting block 4, and a friction pad 12 is provided on one side of the support plate 3 to increase friction, and one end of the adjusting bolt 11 abuts against the surface of the friction pad 12.

[0027] After rotating the adjusting bolt 11, the adjusting bolt 11 can be abutted against one side of the support plate 3, so as to fix the position of the adjusting block 4. A fixing mechanism is also provided at the position where the positioning plate 5 is connected to the adjusting block 4 to fix the position of the positioning plate 5, making the positioning of the sprue more accurate and reducing deviation. The surface of the friction pad 12 is polished rough, so as to increase the friction force during the contact between the adjusting bolt 11 and the friction pad 12, and it is more difficult to shake during fixing.
