Description

Technical Field

[0001] This utility model belongs to the field of environmental testing technology, and in particular relates to a cutting device for mold manufacturing. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, molds are tools used to make shaped items. These tools are composed of various parts, and different molds are composed of different parts.

[0003] In the production and processing of existing molds, the materials required for processing the mold need to be cut. When processing cylindrical molds, round steel needs to be cut to form blocks of the appropriate size. When cutting round steel, a corresponding cutting device is required. The current cutting device requires positioning the round steel before cutting it with a cutting disc. During cutting, when the outer diameter of the round steel is large, the cutting disc needs to penetrate deep into the round steel, which can easily cause the disc to get stuck, accelerate the wear of the cutting disc, and make it difficult to use a rotating roller to drive the round steel to rotate and cut evenly. Summary of the Invention

[0004] In view of this, the present invention aims to provide a cutting device for mold manufacturing, so as to solve the technical problem that it is inconvenient to use a rotating roller to drive round steel for uniform cutting.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A cutting device for mold manufacturing includes a base, a slide rail fixedly installed on one side of the top of the base, a slider slidably installed on the slide rail, a bracket fixedly connected to the top of the slider, a first servo motor fixedly installed on one side wall of the bracket, and a cutting disc movably passing through the bracket.

[0007] A support seat is fixedly installed on one side of the top of the base. A pressure block is connected to the support seat. A V-shaped groove is opened at the bottom of the pressure block and the top of the support seat. An installation groove is opened on both sides of the inner cavity of the groove. A rotating roller is rotatably installed in the installation groove. A second servo motor is fixedly installed at one end of the support seat. The drive shaft of the second servo motor passes through the support seat and is fixedly connected to the end of one of the rotating rollers.

[0008] It should be understood that the round steel is first placed between the bearing seat and the pressure block. Then, the first electric push rod drives the pressure block to descend, thereby applying pressure to the round steel to stabilize it. Four rotating rollers apply pressure to the round steel, and then the slider moves along the slide rail, thereby moving the cutting disc. The first servo motor drives the cutting disc to rotate, thereby cutting the round steel. During the cutting process, the second servo motor drives one of the rotating rollers to rotate, thereby driving the round steel to rotate. This allows the cutting disc to cut the round steel evenly and shortens the depth the cutting disc penetrates into the round steel during the cutting process. This helps to reduce the occurrence of clipping, thereby reducing the wear of the cutting disc and extending its service life.

[0009] Furthermore, limit rods are fixedly installed on all four sides of the top of the bearing seat, and limit holes are opened at the bottom of the pressure block corresponding to the limit rods, with the limit rods being movably inserted into the limit holes.

[0010] Furthermore, the support seat has a recessed groove on one end face corresponding to the cutting disc, and a limiting groove is formed on the inner wall of the recessed groove. A matching limiting slider is inserted into the inner cavity of the limiting groove. A brush plate is connected to the outer wall of the limiting slider, and brush bristles are installed on the brush plate, which are in contact with one side wall of the cutting disc. A spring is fixedly connected to the bottom of the limiting slider, and the tail end of the spring is fixedly connected to the bottom of the inner cavity of the limiting groove. One end of one of the rotating rollers movably passes through the support seat and is fixedly connected to an eccentric wheel. The cutting disc rotates... During the cutting process, the brush plate can brush off the debris on the cutting disc, reducing the adhesion of debris to the inner wall of the cutting disc. As the rotating roller rotates, it drives the eccentric wheel to rotate, which impacts the top of the brush plate. This causes the brush plate to drive the limit slider to compress the spring. When the eccentric wheel disengages from the brush plate, the spring pushes back, causing the limit slider and the brush plate to vibrate up and down, which shakes off the debris. This helps to reduce the accumulation of debris on the brush bristles and improves the effect of debris removal.

[0011] Furthermore, the outer wall of the limiting slider is rotatably connected to a short shaft, and a torsion spring is fixedly fitted on the outer wall of the short shaft. The outer end of the short shaft is fixedly connected to the brush plate. When the eccentric wheel impacts the brush plate, the brush plate can rotate using the short shaft while vibrating up and down. Under the energy storage of the torsion spring, the brush plate can reciprocate, thereby improving the vibration effect and thus helping to improve the effect of shaking off debris.

[0012] Furthermore, it also includes a drive assembly, which includes a fixed frame that is fixedly installed on one side wall of the base. A second electric push rod is fixedly installed on one side wall of the fixed frame. The outer end of the push rod of the second electric push rod is fixedly connected to the side wall of the bracket. The second electric push rod can drive the bracket to move, thereby enabling the slider to move along the slide rail, thus realizing the stable linear movement of the drive cutting disc.

[0013] Furthermore, connection holes are provided at the four corners of the bottom of the base.

[0014] Compared with the prior art, the cutting device for mold manufacturing described in this utility model has the following advantages:

[0015] The cutting device for mold manufacturing described in this utility model has rotating rollers installed in the grooves of the bearing seat and the pressure block. When positioning the round steel, one of the rotating rollers can drive the round steel to rotate. Therefore, during the cutting process, the cutting disc does not need to be fully inserted into the round steel, which helps to reduce the depth of the cutting disc insertion, thereby reducing the occurrence of clipping, reducing the wear of the cutting disc, and extending the service life of the cutting disc.

[0016] The cutting device for mold manufacturing described in this utility model can drive the eccentric wheel to rotate during the rotation of the rotating roller, thereby causing the brush plate to vibrate in multiple directions. This can shake off the debris on the brush bristles, thereby improving the brush plate's ability to remove debris from the surface of the cutting disc. This helps to reduce the situation where debris remains on the cutting disc, causing accelerated wear, and thus helps to extend the service life of the cutting disc. Attached Figure Description

[0028] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] like Figure 1-5 As shown in the figure, as an embodiment, a cutting device for mold manufacturing includes a base 1, a slide rail 11 is fixedly installed on one side of the top of the base 1, a slider 12 is slidably installed on the slide rail 11, a bracket 13 is fixedly connected to the top of the slider 12, a first servo motor is fixedly installed on one side wall of the bracket 13, and the drive shaft of the first servo motor moves through the bracket 13 and is fixedly connected to a cutting disc 14.

[0030] Specifically, the first servo motor can drive the cutting disc 14 to rotate, thereby cutting the material. The slider 12 moves along the slide rail 11, thereby driving the cutting disc 14 to move and completely cut the material.

[0031] A bearing seat 2 is fixedly installed on one side of the top of the base 1. A pressure block 21 is connected to the bearing seat 2. A first electric push rod 23 is fixedly installed on one side wall of the bearing seat 2. The outer end of the push rod of the first electric push rod 23 is fixedly connected to the side wall of the pressure block 21. A V-shaped groove is opened at the bottom of the pressure block 21 and the top of the bearing seat 2. An installation groove is opened on both sides of the inner cavity of the groove. A rotating roller 24 is rotatably installed in the installation groove. A second servo motor 25 is fixedly installed at one end of the bearing seat 2. The drive shaft of the second servo motor 25 passes through the bearing seat 2 and is fixedly connected to the end of one of the rotating rollers 24.

[0032] It should be understood that in actual use, the round steel is first placed between the bearing seat 2 and the pressure block 21. Then, the first electric push rod 23 drives the pressure block 21 to descend, thereby applying pressure to the round steel to stabilize it. The round steel is pressed by four rotating rollers 24. Then, the slider 12 moves along the slide rail 11, thereby moving the cutting disc 14. The first servo motor drives the cutting disc 14 to rotate, thereby cutting the round steel. During the cutting process, the second servo motor 25 drives one of the rotating rollers 24 to rotate, thereby driving the round steel to rotate. This allows the cutting disc 14 to cut the round steel evenly and shortens the depth of the cutting disc 14 into the round steel during the cutting process. This helps to reduce the occurrence of clipping, thereby reducing the wear of the cutting disc 14 and extending its service life.

[0033] It is worth mentioning that limit rods 22 are fixedly installed on all four sides of the top of the bearing seat 2, and limit holes are opened at the bottom of the pressure block 21 corresponding to the limit rods 22, and the limit rods 22 are movably inserted into the limit holes;

[0034] It should be understood that during the descent of the pressure block 21, the limiting rod 22 is inserted into the limiting hole, thereby limiting the lifting trajectory and making the descent of the pressure block 21 stable.

[0035] It should be noted that the base 1 has connection holes at the four corners of its bottom. These connection holes are used to connect with the mounting point using bolts, thereby enabling the overall installation and fixation of the device.

[0036] like Figure 1-2 As shown, in one embodiment, it also includes a drive assembly, which includes a fixing frame 15. The fixing frame 15 is fixedly installed on one side wall of the base 1. A second electric push rod 16 is fixedly installed on one side wall of the fixing frame 15. The outer end of the push rod of the second electric push rod 16 is fixedly connected to the side wall of the bracket 13.

[0037] It should be understood that the second electric actuator 16 can drive the bracket 13 to move, thereby enabling the slider 12 to move along the slide rail 11, thus achieving stable linear movement of the driving cutting disc 14.

[0038] like Figure 3-5 As shown in the embodiment, the bearing seat 2 has a recessed groove on one end face corresponding to the cutting disc 14. The inner wall of the recessed groove has a limiting groove 27. A matching limiting slider 31 is inserted into the inner cavity of the limiting groove 27. A brush plate 3 is connected to the outer wall of the limiting slider 31. Brush bristles are installed on the brush plate 3 and are attached to one side wall of the cutting disc 14. A spring 32 is fixedly connected to the bottom of the limiting slider 31. The tail end of the spring 32 is fixedly connected to the bottom of the inner cavity of the limiting groove 27. One end of one of the rollers 24 moves through the bearing seat 2 and is fixedly connected to an eccentric wheel 26.

[0039] It should be understood that during the cutting process of the cutting disc 14, the brush plate 3 can brush off the debris on the cutting disc 14, reducing the adhesion of debris to the inner wall of the cutting disc 14. In addition, during the rotation of the rotating roller 24, the eccentric wheel 26 can be driven to rotate, so that the eccentric wheel 26 can impact the top of the brush plate 3. As a result, the brush plate 3 will drive the limiting slider 31 to compress the spring 32. When the eccentric wheel 26 disengages from the brush plate 3, the spring 32 pushes back, so that the limiting slider 31 and the brush plate 3 can generate up and down amplitude, thereby shaking off the debris. This helps to reduce the accumulation of debris on the brush bristles and improve the effect of debris removal.

[0040] It should be noted that during the cutting process, coolant is sprayed onto the outer wall of the cutting disc 14 through the coolant nozzle, thereby cooling the cutting disc 14 and flushing away debris from the outside of the cutting disc 14. This is existing technology and is not described in detail in this article.

[0041] It is worth noting that the outer wall of the limiting slider 31 is rotatably connected to a short shaft 33, the outer wall of the short shaft 33 is fixedly fitted with a torsion spring 34, and the outer end of the short shaft 33 is fixedly connected to the brush plate 3.

[0042] It should be understood that when the eccentric wheel 26 impacts the brush plate 3, the brush plate 3 can rotate using the short shaft 33 while vibrating up and down, and with the energy stored in the torsion spring 34, the brush plate 3 can reciprocate, thereby improving the vibration effect and thus helping to improve the effect of shaking off debris.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
