[0003] Magnesium oxide rods require a special extrusion die for extrusion molding during the forming process. However, existing extrusion dies have fewer forming and discharge channels, and the magnesium oxide rods after extrusion are easily subjected to friction, resulting in surface defects on the magnesium oxide rods.

[0004] Therefore, it is essential to provide a special extrusion die for forming magnesium oxide rods to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a special extrusion die for forming magnesium oxide rods. This special extrusion die for forming magnesium oxide rods is movably positioned on the extruder body through a multi-channel rolling support mechanism, which rolls and supports the magnesium oxide rods extruded from several forming channels, reducing the contact area with the magnesium oxide rods, reducing the defect rate of the magnesium oxide rods, and improving the extrusion efficiency of the magnesium oxide rods.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A special extrusion die for forming magnesium oxide rods is provided, including an extruder body, an extrusion end face on the extruder body, a material extrusion channel horizontally opened inside the extruder body, an extrusion column movably inserted into one end of the material extrusion channel, and a plurality of forming channels between the other end of the material extrusion channel and the extrusion end face of the extruder body, and a multi-channel rolling support mechanism movably installed on the extruder body.

[0008] The multi-channel rolling support platform mechanism includes a support platform base and several rolling material support components corresponding to the forming channels. The several rolling material support components are fixedly connected to each other as a whole by connecting columns. Four C-shaped frames are fixedly installed on the support platform base, and every two C-shaped frames connect the outer sides of one end of several rolling material support components.

[0009] Specifically, the extruder body is provided with a positioning slot, and a positioning insert plate is fixedly installed on the support base. The positioning insert plate is movably connected with the positioning slot. A locking positioning plate is fixedly installed at the bottom of the end of the support base near the extrusion end face. A locking bolt is screwed on the locking positioning plate, and the locking bolt is screwed and locked with the extruder body.

[0010] Preferably, the rolling material support assembly includes a material support frame, and several parallel rollers are rotatably mounted inside the material support frame, with the rollers distributed and installed along the axial direction of the forming channel.

[0011] Specifically, a cutting slit is provided between the rolling material support assembly and the extrusion end face.

[0012] Furthermore, the extruder body is provided with a guide groove inside, and two guide rods are fixedly installed at the end of the extrusion column away from the extrusion end face, with the guide rods movably engaging with the guide groove.

[0013] Furthermore, a feeding hopper is installed on the extruder body, the outlet of the feeding hopper is connected to the extrusion channel, and a shut-off valve is fixedly installed on the feeding hopper.

[0041] The present invention will be further described in conjunction with the following embodiments.

[0042] Example 1.

[0043] like Figure 1-3 As shown, a special extrusion die for forming magnesium oxide rods includes an extruder body 1, an extrusion end face 2 on the extruder body 1, a material extrusion channel 3 horizontally opened inside the extruder body 1, an extrusion column 4 movably inserted into one end of the material extrusion channel 3, and a plurality of forming channels 5 between the other end of the material extrusion channel 3 and the extrusion end face 2 of the extruder body 1, and a multi-channel rolling support mechanism 6 movably installed on the extruder body 1.

[0044] This application is used for extruding magnesium oxide rods. First, the raw material is extruded through the extruder body 1 and formed from the extrusion end face 2. The magnesium oxide rod raw material is placed inside the extrusion channel 3. Then, it is horizontally extruded through the extrusion column 4, which extrudes the magnesium oxide rod away from the extrusion into the interior of several forming channels 5 to form the shape of the magnesium oxide rod. Finally, it comes out from the extrusion end face 2. The formed magnesium oxide rod cooperates with the multi-channel rolling support mechanism 6. The magnesium oxide rod is supported on the multi-channel rolling support mechanism 6 and rolls.

[0045] The multi-channel rolling support mechanism 6 includes a support base 7 and several rolling material support components 8 corresponding to the forming channel 5. The several rolling material support components 8 are fixedly connected to each other by connecting columns 9 to form a whole. Four C-shaped frames 10 are fixedly installed on the support base 7. Every two C-shaped frames 10 connect the outer sides of one end of several rolling material support components 8.

[0046] The multi-channel rolling support mechanism 6 is positioned by the support base 7, and the extruded magnesium oxide rod is supported by the rolling material support assembly 8. Each rolling material support assembly 8 corresponds to a forming channel 5 and is located below the forming channel 5. The two ends of the multiple rolling material support assemblies 8 are connected by connecting columns 9 to form a whole, which is convenient for transportation and fixing. At the same time, four C-shaped frames 10 are installed around the outside of the multiple rolling material support assemblies 8. Every two C-shaped frames 10 are located at one end of the rolling material support assembly 8 to realize external connection. The multiple rolling material support assemblies 8 are connected into a whole on the outside.

[0047] The extruder body 1 is provided with a positioning slot 11, and a positioning plate 12 is fixedly installed on the support base 7. The positioning plate 12 is movably inserted into the positioning slot 11. A locking positioning plate 13 is fixedly installed at the bottom of one end of the support base 7 near the extrusion end face 2. A locking bolt 14 is screwed on the locking positioning plate 13. The locking bolt 14 is also screwed into the extruder body.

[0048] To ensure the accurate positioning of the rolling material support assembly 8, the positioning plate 12 and the positioning slot 11 are engaged to achieve positioning, and the position of the rolling material support assembly 8 is locked by the locking bolt 14.

[0049] The rolling material support assembly 8 includes a material support frame 15, and several parallel rollers 16 are rotatably mounted inside the material support frame 15. The rollers 16 are distributed and installed along the axial direction of the forming channel 5.

[0050] The rolling support assembly 8 supports the magnesium oxide rod by rolling the roller 16. After the magnesium oxide rod comes out of the extruder body 1, the bottom of the magnesium oxide rod directly overlaps the top surface of the roller 16.

[0051] A cutting slit 17 is provided between the rolling material support assembly 8 and the extrusion end face 2.

[0052] Cutting slit 17 facilitates the cutting of magnesium oxide rods.

[0053] The extruder body 1 has a guide groove 18 inside. Two guide rods 19 are fixedly installed at the end of the extrusion column 4 away from the extrusion end face 2. The guide rods 19 are in movable cooperation with the guide groove 18.

[0054] The coordinated installation of guide groove 18 and guide rod 19 can improve the accuracy of the movement of extrusion column 4.

[0055] A feeding hopper 20 is installed on the extruder body 1. The outlet of the feeding hopper 20 is connected to the extrusion channel 3. A shut-off valve 21 is fixedly installed on the feeding hopper 20.

[0056] The hopper 20 is used to store magnesium oxide raw materials, and the output of magnesium oxide raw materials is controlled by the shut-off valve 21.

[0057] This invention uses a multi-channel rolling support mechanism 6, which is movably positioned on the extruder body 1, to roll and support the magnesium oxide rods extruded from several forming channels 5, thereby reducing the contact area with the magnesium oxide rods, lowering the defect rate of the magnesium oxide rods, and improving the extrusion efficiency of the magnesium oxide rods.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
