[0031] The present invention will now be described in further detail with reference to the accompanying drawings and specific preferred embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. "First," "second," etc., do not indicate the importance of the components, and therefore should not be construed as a limitation of this utility model. The specific dimensions used in this embodiment are only for illustrating the technical solution and do not limit the protection scope of this utility model.
[0033] like Figure 1-6 As shown, a roll tooling molding and positioning device includes a positioning base plate 1, a box pattern 2 detachably installed on the positioning base plate 1, and a heightening ring pattern 3 detachably installed on the top of the box pattern 2. The positioning base plate 1, the box pattern 2, and the heightening ring pattern 3 are coaxially distributed and combined to form a molding mold 01. The box pattern 2 and the heightening ring pattern 3 are both set as cylindrical structures with open ends. During molding, a roll pattern mold 4 is inserted into the axis of the molding mold 01. The roll pattern mold 4 is selected and designed according to the actual roll size to be processed. A molding sand layer 02 is filled between the roll pattern mold 4 and the box pattern 2. During filling, a tamping mechanism is needed to tamp the molding sand. After molding, the roll pattern mold 4 is pulled out to form a mold cavity 03 in the molding sand layer 02. The mold cavity 03 is used to cast the roll workpiece.
[0034] The top of the positioning base plate 1 is provided with a coaxially distributed convex ring 5, and a first pad 6 and a second pad 7 are movably provided on the outer and inner sides of the convex ring 5, respectively. The first pad 6 is fitted between the inner wall of the box sample 2 and the outer wall of the convex ring 5, and the second pad 7 is fitted between the inner wall of the convex ring 5 and the outer wall of the roll sample mold 4. The width of the first pad 6 and the second pad 7 can be selected and designed according to the actual processing needs, so that the positioning base plate 1 and the box sample 2 can be stably combined, and the roll sample mold 4 can be effectively positioned and supported, improving the stability of the roll sample mold 4 during mold making, so that the mold cavity 03 can remain vertical after the roll sample mold 4 is pulled out, reducing workpiece processing errors and improving product quality.
[0035] Specifically, both the first pad 6 and the second pad 7 include multiple arc-shaped plates, and the multiple arc-shaped plates of the first pad 6 and the second pad 7 are arranged in a ring array to form a complete ring component. In this embodiment, when multiple arc-shaped plates form a complete ring component, the ends of two adjacent arc-shaped plates abut against each other, thereby improving the stability between the structures.
[0036] A support mechanism 8 is installed on the raised ring 3 to position and support the top outer side of the roll pattern 4, further improving the stability of the roll pattern 4 during molding, so that the mold cavity 03 can remain vertical after the roll pattern 4 is pulled out, reducing workpiece processing errors and improving product quality.
[0037] Specifically, the height of the first pad 6 and the second pad 7 is greater than the thickness of the convex ring 5, which improves the stability of the roll die 4 when it is erected.
[0038] Specifically, the support mechanism 8 includes at least three positioning blocks 81, which are distributed around the outside of the roll mold 4. A lead screw 82 is threaded through and connected to the positioning block 81. The end of the lead screw 82 is rotatably connected to an abutment block 83 that matches the outer wall of the roll mold 4. By rotating the lead screw 82, it moves along the axial direction of the lead screw 82 on the positioning block 81, so that the multiple abutment blocks 83 simultaneously abut against the outside of the roll mold 4, so that the roll mold 4 is evenly stressed and supported and limited from the top of the roll mold 4.
[0039] Specifically, the top of the raised ring sample 3 is fixedly connected to a track 84, and the positioning block 81 is provided with a track groove 85 that slides with the track 84. The positioning block 81 slides around the track 84 through the track groove 85, so that the lead screw 82 can move, avoiding blocking the top of the box sample 2 and the raised ring sample 3, so that the molding sand can be evenly compacted after entering the cavity between the box sample 2 and the raised ring sample 3, without any blind spots.
[0040] Specifically, a combination plate 86 is fixedly connected to multiple positioning blocks 81, and the thickness of the combination plate 86 is less than the thickness of the heightening ring 3, so that multiple positioning blocks 81 can be moved synchronously at the same time, while maintaining the distance between adjacent positioning blocks 81.
[0041] Specifically, the inner diameters of box sample 2 and heightened ring sample 3 are equal.
[0042] Specifically, flange plates 9 are integrally provided on the top and bottom of box sample 2 and the outer side of the bottom of heightened ring sample 3, and the flange plates 9 are fixedly connected to the outer wall of box sample 2 or heightened ring sample 3 with reinforcing ribs to improve the overall strength of the device and extend the service life of the device.
[0043] Specifically, the flange plate 9 has multiple pin holes 10, the positioning base plate 1 has pin holes 10, and the multiple pin holes 10 on the positioning base plate 1 and the flange plate 9 are distributed in a one-to-one correspondence and are combined by pins 11, which facilitates the assembly and installation of the device and its subsequent disassembly.
[0044] Specifically, the outer wall of the positioning base plate 1 is fixedly connected with a lifting rod 12, and the number of lifting rods 12 is set to multiple, which are arranged in a ring array to facilitate the hoisting and placement of the device.
[0045] In use, the positioning base plate 1, box pattern 2, and heightening ring pattern 3 are sequentially stacked and assembled into a molding mold 01 through pin holes 10 and pins 11. Multiple arc-shaped plates form a complete ring component, creating a first pad layer 6 and a second pad layer 7, improving the fit and stability between the structures. The bottom end of the roll pattern 4 is inserted into the axial part of the molding mold 01. By rotating the lead screw 82, it moves along the axial direction of the lead screw 82 on the positioning block 81, causing multiple abutment blocks 83 to simultaneously abut against the outside of the roll pattern 4, ensuring uniform force on the roll pattern 4. Support is then provided from the top of the roll pattern 4. The molding sand is filled and compacted between the roll mold 4 and the box mold 2 through the opening at the top of the molding mold 01 to form a molding sand layer 02. During the process, the roll mold 4 is effectively supported and fixed, and will not be eccentric or tilted due to vibration. The positioning block 81 slides in a circular shape on the track 84 through the rail groove 85, so that the lead screw 82 can move, avoiding blocking the top of the box mold 2 and the heightened ring mold 3, so that the molding sand can be evenly compacted after entering the cavity between the box mold 2 and the heightened ring mold 3, without blind spots. After molding, the roll mold 4 is pulled out to form a mold cavity 03 in the molding sand layer 02, and the roll workpiece is cast.
[0046] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
