[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] Embodiment 1:

[0030] A lost foam cutting device comprises a wire saw 1 and a workbench 2, wherein the wire saw 1 is fixedly mounted on the top of the workbench 2, and a fixing mechanism is arranged on the top of the workbench 2 to fix the lost foam;

[0031] The fixing mechanism includes two motors 3 fixedly mounted on both sides of the workbench 2. Two square slots 4 are provided on the top of the workbench 2. The output end of the motor 3 passes through the inside of the square slot 4 and is fixedly connected with a rotating rod 5. One end of the rotating rod 5 is fixedly connected with a threaded rod 6. The surface of the threaded rod 6 is transmission-connected with a transmission block 7. The top of the transmission block 7 is fixedly connected with a clamping plate 8. An adjustment mechanism is provided on one side of the clamping plate 8, which can play a role in fixing the special-shaped lost foam.

[0032] In this embodiment, by setting a fixing mechanism, when the user uses the wire saw machine 1 to cut the foam block, by starting the motor 3 in the fixing mechanism, the motor 3 rotates to drive the rotating rod 5 and the threaded rod 6 to rotate, and the external thread on the surface of the threaded rod 6 squeezes the internal thread inside the threaded hole 23, so that the transmission block 7 drives the sliding block 21 and the clamping plate 8 to approach the two sides of the disappearing film foam along the trajectory of the sliding groove 22 until it moves to clamp it, so as to play the role of fixing it;

[0033] The invention solves the problem that when the existing cutting device is used to cut some larger lost foams, the user needs to manually support the lost foam. However, this manual support method is inefficient and not only poses a safety hazard, but also the hand is prone to shaking during the support process, which results in an uneven cut surface of the lost foam after cutting, affecting the quality of the finished product.

[0034] The bottom solid block of the transmission block 7 is connected with a sliding block 21, and the inner wall of the square groove 4 is provided with a sliding groove 22 used in conjunction with the sliding block 21;

[0035] By providing the sliding block 21 and the sliding groove 22 , when the transmission block 7 moves, the sliding block 21 can be driven to move along the track of the sliding groove 22 , thereby limiting the moving track of the transmission block 7 .

[0036] A threaded hole 23 is provided on one side of the transmission block 7, and the threaded hole 23 is used in conjunction with the threaded rod 6;

[0037] By providing the threaded hole 23 , the internal thread inside the threaded hole 23 can be squeezed by the external thread on the surface of the threaded rod 6 , so that the transmission block 7 drives the sliding block 21 to move along the track of the sliding groove 22 .

[0038] A bearing 24 is provided at one end of the threaded rod 6, and one end of the threaded rod 6 is rotatably connected to the inner wall of the square groove 4 through the bearing 24;

[0039] By providing the bearing 24 , the threaded rod 6 can rotate around the rotation track of the bearing 24 when it rotates, thereby limiting the rotation track of the threaded rod 6 .

[0040] Embodiment 2:

[0041] On the basis of the first embodiment, the fixing mechanism in the first embodiment can play the role of fixing the lost foam, but this mechanism does not have the function of fixing the special-shaped lost foam. When the user needs to cut the concave and convex special-shaped lost foam, the clamping plate 8 in this mechanism cannot fix it well, and it will shake during the cutting process, thereby causing the cutting position to shift, which will also affect the quality of the finished product. The adjustment mechanism in this application includes a fixing frame 9 fixedly connected to one side of the clamping plate 8. The number of the fixing frames 9 is several. The top of the fixing frame 9 is fixedly connected to a stabilizing frame 10. The bottom of the fixing frame 9 is provided with a cylindrical hole 11. The hole 11 is movably connected with a plug block 12 inside, and a plug column 13 is fixedly connected to the top of the plug block 12. One end of the plug column 13 passes through the top of the stabilizing frame 10 and is fixedly connected to a stabilizing block 14. A tension spring 15 is fixedly connected to the top of the plug block 12, and one end of the tension spring 15 is fixedly connected to the bottom of the stabilizing frame 10. A plurality of storage grooves 16 are provided on one side of the clamping plate 8. A fixed plate 17 is provided inside the storage groove 16. A pull-out plate 18 is fixedly connected to one side of the fixed plate 17. One end of the pull-out plate 18 passes through one side of the fixing frame 9 and is fixedly connected to a stabilizing plate 19. A plug hole 20 used in conjunction with the plug column 13 is provided on the top of the pull-out plate 18.

[0042] By setting an adjustment mechanism in this embodiment, when the user needs to cut the uneven special-shaped disappearing film foam, he can use the fixing mechanism and manually pull the stabilizing block 14, so that the tension generated by the tension spring 15 can drive the plug-in column 13 and the plug-in block 12 to disengage from the cylindrical hole 11 and the plug-in hole 20. At this time, the stabilizing plate 19 can be manually pushed to make the stabilizing plate 19 drive the pulling plate 18, the fixing plate 17 and the anti-slip plate 25 to move toward the concave and convex part of the special-shaped block foam until the fixing plate 17 and the anti-slip plate 25 are moved to fit closely with the concave and convex part of the special-shaped block foam. Then, the stabilizing block 14 can be manually moved to make the stabilizing block 14 drive the tension spring 15, the plug-in column 13 and the plug-in block 12 to be inserted into the cylindrical hole 11 through the plug-in hole 20, so as to fix the special-shaped block foam.

[0043] By providing the anti-slip plate 25, the contact area and friction force between the special-shaped block foam and the fixing plate 17 are increased, so that the fixing effect is better, thereby further improving the fixing effect of the fixing mechanism, and solving the problem that this mechanism does not have the function of fixing the special-shaped lost foam foam. When the user needs to cut the concave and convex special-shaped lost foam, the clamping plate 8 in this mechanism cannot fix it well, and it will shake during the cutting process, thereby causing the cutting position to shift, which will also affect the quality of the finished product.

[0044] One side of the fixing plate 17 is fixedly connected with an anti-skid plate 25, and the material of the anti-skid plate 25 is silicone;

[0045] By setting the anti-skid plate 25 and making the material of the anti-skid plate 25 as silicone, the contact area and friction force between the special-shaped block foam and the fixing plate 17 can be increased through the anti-skid plate 25, so that the fixing effect is better.

[0046] The number of the plug holes 20 is several and evenly distributed on the surface of the pull-out plate 18;

[0047] By setting a number of insertion holes 20 and evenly distributing them on the surface of the pull-out plate 18, the pull-out plate 18 can drive the fixing plate 17 and the anti-slip plate 25 to adjust according to the different positions of the concave and convex parts of the special-shaped block foam, thereby fixing the concave and convex parts.

[0048] Working principle: When the user uses the wire saw machine 1 to cut the foam block, the motor 3 in the fixing mechanism is started, and the rotation of the motor 3 drives the rotating rod 5 and the threaded rod 6 to rotate, and the external thread on the surface of the threaded rod 6 squeezes the internal thread inside the threaded hole 23, so that the transmission block 7 drives the sliding block 21 and the clamping plate 8 to approach the two sides of the disappearing film foam along the trajectory of the sliding groove 22 until it moves to clamp it, so as to play the role of fixing it;

[0049] When the user needs to cut the uneven special-shaped disappearing film foam, the user can use the fixing mechanism and manually pull the stabilizing block 14, so that the tension generated by the tension spring 15 can drive the plug-in column 13 and the plug-in block 12 to disengage from the cylindrical hole 11 and the plug-in hole 20. At this time, the stabilizing plate 19 can be manually pushed to make the stabilizing plate 19 drive the pulling plate 18, the fixing plate 17 and the anti-slip plate 25 to move toward the concave and convex part of the special-shaped block foam until the fixing plate 17 and the anti-slip plate 25 are moved to fit closely with the concave and convex part of the special-shaped block foam. Then, the stabilizing block 14 can be manually moved to make the stabilizing block 14 drive the tension spring 15, the plug-in column 13 and the plug-in block 12 to be inserted into the cylindrical hole 11 through the plug-in hole 20, so as to fix the special-shaped block foam. By setting the anti-slip plate 25, the contact area and friction between the special-shaped block foam and the fixing plate 17 are increased, so that the fixing effect is better, thereby further improving the fixing effect of the fixing mechanism.

[0050] It should be noted that the wire saw machine 1 and the motor 3 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. The specific composition and principle of the power supply of the wire saw machine 1 and the motor 3 are clear to those skilled in the art, so they will not be described in detail.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
