Technical Field

[0001] The utility model relates to the technical field of extrusion mould manufacturing, in particular to a milling machine for grinding extrusion moulds. Background Art

[0002] An extrusion mold is a tool used to manufacture plastic products. It is mainly composed of a front mold, a rear mold, a core rod, a fixing plate, an extrusion port, and a plastic feeding system. After the extrusion mold is made, the surface of the mold needs to be polished for smoothness, so a milling machine is needed. A milling machine is a machine tool for processing metal, plastic, wood and other materials. It uses a rotating tool to cut the surface of the workpiece to achieve the processing purpose.

[0003] At present, the existing milling machines for grinding extrusion molds are not equipped with protective devices. Therefore, when the turning tool on the cutter disc works for a long time, it is easy to cause the turning tool to loosen, thereby causing the risk of flying cutters injuring people. At the same time, the lack of protective devices during work will also cause iron chips to splash everywhere, greatly reducing safety. At the same time, there is no iron chip collection device installed, so it is not easy to collect iron chips during use, reducing the convenience of use. Summary of the invention

[0004] The main purpose of the utility model is to solve the problem that the above-mentioned existing milling machine for grinding extrusion molds has no protective device, so the turning tool is prone to loosening during long-term work, thereby causing flying tools to injure people, and it is not convenient to block the processing iron chips to prevent splashing. At the same time, there is no iron chip collection device installed, which is not convenient for centralized processing of iron chips, thereby reducing the convenience of use and the safety of the operator. A milling machine for grinding extrusion molds is provided.

[0005] The specific scheme of the utility model is: a milling machine for grinding extrusion molds, including a transmission mechanism, a base and a cutter disc, a material receiving box is provided below the cutter disc, the top of the material receiving box is open, a slider is fixed to the bottom of the material receiving box, a dovetail groove is provided at the inner top of the base, the slider is slidably connected to the dovetail groove, handles are provided at both ends of the material receiving box, a protective cover is detachably connected to the handle, and the protective cover is located above the cutter disc and semi-surrounds the cutter disc.

[0006] According to the above technical solution, the protective cover half-wraps the cutter disc to avoid iron chips from flying around, and the iron chips can be collected by the receiving box below, and the turning tool on the cutter disc can be effectively prevented from falling off and causing flying tools.

[0007] Furthermore, a connecting plate is fixed to the bottom of the protective cover, a slot is provided at the top of the handle, the top of the handle is open and the middle is hollow, and the connecting plate matches the slot and is movably connected.

[0008] According to the above technical solution, the protective cover can be installed quickly and conveniently by connecting the connecting plate and the slot. At the same time, the middle of the handle is hollowed out, which can also facilitate subsequent staff to lift the receiving box through the handle.

[0009] Furthermore, a light strip is provided inside the protective cover, and a transparent plate is provided on the inner wall of the protective cover.

[0010] According to the above technical solution, the cutter disc under the protective cover can be illuminated by the light strip, which makes it easy to observe the turning tool on the cutter disc when working at night. When looseness occurs, it can be dealt with in time. The transparent plate can effectively protect the light strip and allow light to pass through.

[0011] Furthermore, the protective cover and the light strip are both semicircular.

[0012] According to the above technical solution, the semicircular design can better wrap the cutter disc to avoid flying cutters, while increasing the shielding surface to reduce the splashing of iron chips. At the same time, the light strip is semicircular.

[0013] Furthermore, the handle is L-shaped.

[0014] According to the above technical solution, the L-shaped setting makes it easier to lift by hand.

[0015] Compared with the prior art, the utility model has the following advantages: the milling machine for grinding extrusion molds is equipped with a protective cover and a material receiving box, which can not only effectively prevent flying knives from injuring people, but also prevent iron filings from flying and guide the iron filings to the material receiving box below for collection, greatly improving the safety of workers and the convenience of use. At the same time, a light strip is installed inside the protective cover to illuminate the working condition of the cutter disc to the greatest extent, thereby further improving the convenience of use of the milling machine for grinding extrusion molds.

[0024] Embodiment 1

[0025] See also Figure 1-7 The present embodiment is a milling machine for grinding extrusion molds, which is composed of a transmission mechanism 1, a base 2 and a cutter disc 3. The transmission mechanism 1 is used to drive the cutter disc 3 to work, and the base 2 is used to support and place the milling machine. A material receiving box 4 is provided directly below the cutter disc 3. The top of the material receiving box 4 is open and a slider 5 is fixed to the bottom. A dovetail groove 6 is provided at the top of the base 2. The slider 5 is slidably connected to the dovetail groove 6 at the top of the base 2. The shape of the slider 5 matches the shape of the dovetail groove 6, so as to achieve the function of installing the material receiving box 4 and improve the silkiness of the material receiving box 4 sliding on the base 2. Handles 7 are provided at both ends of the material receiving box 4. A protective cover 8 is detachably connected to the handle 7, which can be detachably connected by bolts or latches. The protective cover 8 is located above the cutter disc 3 and semi-surrounds it, so as to wrap the cutter disc 3 to the greatest extent, prevent the flying knife on the cutter disc 3 from being thrown out, and at the same time, it can also block iron filings to avoid splashing.

[0026] The working principle of this embodiment is as follows: during installation, first push the slider 5 at the bottom of the material receiving box 4 into the dovetail groove 6, install the material receiving box 4 just below the cutter disc 3 to receive the material, and then fix the protective cover 8 to the handles 7 at both ends of the material receiving box 4 by bolts or latches to complete the installation. When the cutter disc 3 is working, the protective cover 8 can not only effectively prevent the staff's hands from accidentally touching the cutter disc 3 and causing safety accidents, but also effectively prevent the flying cutter from loosening and causing injuries. The protective cover 8 half surrounds the cutter disc 3, which can effectively prevent iron chips from flying, and the iron chips flying on the inner side of the protective cover 8 play a guiding effect, falling down to the material receiving box 4 for storage, which greatly improves the safety and convenience of using the milling machine for grinding extrusion molds.

[0027] Embodiment 2

[0028] The structure of this embodiment is basically the same as that of the first embodiment, and the following features are added on the basis of the first embodiment: two connecting plates 9 are fixed to the bottom of the protective cover 8, and the slot 10 is arranged on the surface of the handle 7. The top of the handle 7 is open and the middle is hollow. The size of the connecting plate 9 matches the slot 10. The connecting plate 9 is inserted into the top opening of the handle 7 to be linked and limited with the connecting plate 9 to achieve the effect of installing the protective cover 8. The connecting plate 9 is movably connected to the handle 7.

[0029] Furthermore, a light strip 11 is installed inside the protective cover 8, and a transparent plate 12 is installed on the inner wall of the protective cover 8. The transparent plate 12 is used to protect the light strip 11 and has a light-transmitting effect.

[0030] Furthermore, the protective cover 8 and the light strip 11 are both semicircular, and the light strip 11 is equivalent to half-wrapping the cutter disc 3, so that the cutter disc 3 can be fully illuminated.

[0031] Furthermore, the handle 7 is L-shaped, which can facilitate the user to lift the receiving box 4.

[0032] The working principle of this embodiment is as follows: during installation, first cover the top of the knife disc 3 with the protective cover 8, and then insert the two connecting plates 9 at the bottom of the protective cover 8 into the slots 10 on the handle 7 for limit installation.
