Description

Technical Field

[0001] The utility model relates to the technical field of mold processing, in particular to a milling machine for mold processing. Background Art

[0002] Mold processing refers to the processing of forming and blanking tools, and also includes shearing dies and die-cutting dies. In the later stage of mold frame processing, the burrs and unevenness on the mold surface need to be polished, so a milling machine is needed to polish the mold surface. The milling machine is a metal cutting machine tool, mainly used for processing planes, curved surfaces and various grooves. It uses the rotation of the milling cutter for the main motion, while the movement of the workpiece and the milling cutter is used as the feed motion to realize the processing of the workpiece.

[0003] At present, when installing the turning tool on the existing milling machine for mold processing, the turning tool is only clamped directly in the installation groove by bolts for processing. Therefore, during a long period of work, the collision between the turning tool and the mold can easily cause the turning tool to shift, thereby reducing the processing stability and processing quality, and even causing flying tools to injure people, greatly reducing the safety of milling machine processing. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing milling machines for mold processing do not have a fixing mechanism for preventing the turning tool from moving and flying, so during use, the turning tool may shift and reduce the processing quality at the least, and the flying tool may injure people at the worst, thereby reducing the processing stability and quality, and also reducing the safety of mold processing, and provide a milling machine for mold processing.

[0005] The specific scheme of the utility model is: a milling machine for mold processing, including a driving mechanism and a cutter disc, a fixed block a and a fixed block b are fixed on the surface of the cutter disc, the fixed block a and the fixed block b are arranged in parallel, a mounting groove is provided between the fixed block a and the fixed block b, a turning tool is detachably installed in the mounting groove, a limiting block is fixedly connected to the surface of the turning tool, a fixing mechanism is detachably installed on the fixed block a, the fixing mechanism includes a positioning plate, an inserting plate is fixed at one end of the positioning plate, a card slot is provided on the surface of the inserting plate and one side of the card slot is open, A screw hole b and a limiting groove a are provided on the surface of the fixing block a, one end of the insert plate passes through the limiting groove a and is movably connected to the limiting groove b, the limiting groove b is provided at one end of the fixing block b, a screw hole a is provided on the positioning plate, a bolt is threadedly connected to the screw hole a, the end of the bolt away from the screw hole a is threadedly connected to the screw hole b, the screw hole a and the screw hole b are coaxial, the limiting groove a is parallel to the limiting groove b, the insert plate matches the limiting groove a and the limiting groove b, the clamping slot is movably connected and matches the limiting block, and the width of the turning tool is smaller than the depth of the mounting groove.

[0006] According to the above technical solution, the turning tool is limited by a fixing mechanism, which improves the stability of the turning tool and prevents the turning tool from flying out due to long-term work.

[0007] Furthermore, the limit block is 2-5 mm higher than the slot.

[0008] According to the above technical solution, by the limit block being higher than the slot, the slot can be effectively limited by the limit block to avoid displacement of the turning tool.

[0009] Furthermore, the depth of the limiting groove b is 2~5mm.

[0010] According to the above technical solution, the inserting plate can be inserted into the limiting groove b by the limiting groove b having a depth of 2 to 5 mm, thereby effectively improving the stability and firmness of the fixation.

[0011] Furthermore, the turning tool and the limiting block are integrally formed.

[0012] According to the above technical solution, the firmness of the limit block is improved by integral molding, thereby preventing the turning tool from being thrown out due to working inertia.

[0013] Compared with the prior art, the utility model has the following advantages: the milling machine for mold processing is equipped with a fixing mechanism to prevent the tool from shifting and flying, which can avoid the tool from shifting due to long-term impact and cutting during work, thereby improving the processing stability and processing quality of the mold processing milling machine; at the same time, the tool can be limited by the card slot and the plug plate on the fixing mechanism, avoiding the tool from flying out directly due to a large movement, reducing the occurrence of safety accidents, improving the safety of mold processing, and further enhancing the practicability of the milling machine for mold processing.

DETAILED DESCRIPTION

[0019] See also Figure 1-4 The present embodiment is a milling machine for mold processing, comprising a driving mechanism 1 and a cutter head 2. The driving mechanism 1 is used to drive the cutter head 2 to rotate so as to achieve the effect of cutting the burrs on the surface of the mold. A plurality of fixed blocks a3 and fixed blocks b4 are fixed on the surface of the cutter head 2. The fixed block a3 is parallel to one side of the fixed block b4. A mounting groove 5 is provided between the fixed block a3 and the fixed block b4. A detachable turning tool 6 is installed inside the mounting groove 5. A limiting block 7 is welded on the surface of the turning tool 6. A fixed block a3 is detachably installed on the left side of the fixed block a3. The mechanism is detachable by bolts 15. The fixing mechanism is used to fix and limit the turning tool 6. The fixing mechanism includes a positioning plate 8. When the positioning plate 8 is installed, it is located on the left side of the fixing block a3. The right end of the positioning plate 8 is welded or integrally formed with an insert plate 9. The surface of the insert plate 9 is hollowed out with a card slot 10. One side of the card slot 10 is provided with an opening. The surface of the fixing block a3 is provided with a screw hole b11 and a limiting groove a12. The screw hole b11 is located below the limiting groove a12 to facilitate the installation of the fixing mechanism. One end of the insert plate 9 passes through the limiting groove a12, and The other end is inserted into the limiting groove b13 to achieve the effect of pressing the turning tool 6 from above. The distance between the limiting groove b13 and the top of the turning tool 6 is 1 mm, which can minimize the gap between the insert plate 9 and the turning tool 6, and improve the limiting and clamping of the insert plate 9 on the turning tool 6. The limiting groove b13 is located on the side wall of one end of the fixing block b4. The positioning plate 8 is provided with a screw hole a14, and the screw hole a14 is threadedly connected with a bolt 15. The bolt 15 is used to fix the fixing mechanism. The bolt 15 passes through the screw hole a14 and is away from the screw hole a14. The end thread is connected to the screw hole b11 to clamp the turning tool 6. The screw hole a14 is coaxial with the screw hole b11 to facilitate the installation of the bolt 15. The limiting groove a12 and the limiting groove b13 are parallel to each other to facilitate the limiting of the plug plate 9. The size and shape of the card slot 10 and the limiting block 7 match each other and are movably connected to achieve the effect of limiting the turning tool 6. The width of the turning tool 6 is less than the depth of the installation groove 5 to facilitate the installation of the turning tool 6, and avoid the turning tool 6 being too thick to block the limiting groove a12 and the limiting groove b13, thereby making it impossible to install the plug plate 9.

[0020] Furthermore, the height of the limit block 7 is 2 to 5 mm higher than the depth of the slot 10, which can effectively improve the limiting effect of the slot 10 on the limit block 7, not only preventing the turning tool 6 from being thrown to one side, but also preventing the turning tool 6 from shifting during the cutting process.

[0021] Furthermore, the depth of the limiting groove b13 is 2-5 mm, which is convenient for the plug board 9 to be inserted therein for limiting and fixing.

[0022] Furthermore, the turning tool 6 and the limiting block 7 are integrally formed, which can improve the firmness of the limiting block 7 and avoid the situation in which the limiting block 7 is broken due to inertia during the rotation and cutting process of the turning tool 6.

[0023] The working principle of this embodiment is as follows: when installing, first place the turning tool 6 inside the installation groove 5, then insert the plug plate 9 of the fixing mechanism into the limiting groove a12, and when the opening of the card slot 10 on the plug plate 9 passes through the limiting block 7, insert the other end of the plug plate 9 into the limiting groove b13, and finally connect the bolt 15 with the screw hole a14 first and then pass it through the screw hole b11 so that the other end of the bolt 15 clamps the turning tool 6 to one side to complete the installation of the turning tool 6 and the fixing mechanism. During the working process, the plug plate 9 on the top of the turning tool 6 can clamp the turning tool 6 from the top , improves the stability of the turning tool 6, thereby improving the quality and stability of the turning tool 6 processing, and at the same time avoids the collision between the turning tool 6 and the cutting of the material during work, which causes the turning tool 6 to shift to the outside or even fly out to the outside, thereby improving the stability and safety of material processing. At the same time, the card slot 10 can limit the limit block 7 to avoid the turning tool 6 from moving forward and backward or even being thrown to one side due to the impact of cutting, further improving the stability and safety of material processing. When disassembling, remove the bolt 15 and take out the insert plate 9.
