Abstract
Description
Technical Field
[0001] This utility model relates to the field of graphite crucible manufacturing technology, and more specifically to a graphite crucible extrusion molding device. Background Technology
[0002] For a long time, graphite crucibles have been formed mainly by vibration molding and graphite electrode forming. However, the products produced by vibration molding have low and uneven density, are prone to cracking during firing, and the length of the crucible is limited by the size of the mold. Graphite crucibles formed by graphite electrodes are expensive, have a complicated processing process, and have a high damage rate.
[0003] Therefore, how to provide a simple, low-cost device for producing graphite crucibles with uniform texture is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the present invention provides a graphite crucible extrusion molding device, which aims to solve the above-mentioned technical problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A graphite crucible extrusion molding apparatus includes a mold, a cutting section and a receiving section;
[0007] One end of the mold is the feeding end and connected to the extruder, and the other end is the forming end; the cutting part includes a support plate and a cutter; the panel of the support plate has a slot corresponding to the forming end of the mold; the cutter is slidably connected to the panel of the support plate and its cutting edge faces the slot.
[0008] The receiving part and the mold are symmetrically arranged on both sides of the support plate; the receiving part includes a support frame and a material receiving groove plate, one end of the bottom surface of the material receiving groove plate is hinged to the upper end of the support frame, and the other end faces the support plate; a receiving groove is provided above the material receiving groove plate and corresponds to the groove opening to receive the extruded crucible.
[0009] The beneficial effects of this utility model are that the graphite crucible is extruded and formed in one step by a mold, and the formed crucible falls into the receiving groove of the material receiving plate through the slot on the support plate. When the length of the crucible falling into the receiving groove meets the required length, the sliding cutter cuts the crucible wall. After cutting, multiple crucibles can be collected by flipping the receiving groove plate. The crucible formed by this device is controllable, and it can reduce manual input and improve production efficiency.
[0010] Preferably, the cutting unit further includes a cutting cylinder, the cylinder body of which is fixed to the panel of the support plate, and its piston rod is fixed to the blade wall of the cutter. The cutting cylinder drives the sliding of the cutter to cut the formed crucible.
[0011] Preferably, the cutting section further includes a support, and the lower end of the support plate is fixed to the top surface of the support. Using the support to support the support plate allows for two advantages: firstly, the height of the support plate can be adjusted to align its groove with the formed crucible; secondly, it ensures the stability of the support plate and guarantees the flatness of the cut after cutting the crucible.
[0012] Preferably, there are multiple cutters, which are arranged radially relative to the slot and their cutting edges correspond to the outer wall of the crucible. This ensures the integrity of the crucible after final collection.
[0013] Preferably, the support frame includes a base plate, uprights, and support columns; there are multiple uprights, and their lower ends are vertically fixed to the top surface of the base plate; there are also multiple support columns, one end of which is fixed to the middle of each upright, and the other end abuts against the bottom surface of one end of the material receiving trough; the bottom surface of the other end of the material receiving trough is hinged to the top of the uprights. The uprights and support columns form a cantilever support structure, which can support the material receiving trough. When the material receiving trough receives a complete crucible, the crucible can be collected by lifting the material receiving trough, which is convenient and labor-saving.
[0014] Preferably, a pin is fixed to the top of the column, and the bottom surface of the material receiving trough is pinned to the pin via an ear plate. The pin enables a hinged connection between the material receiving trough and the column.
[0015] Preferably, a baffle is fixed to one end of the material receiving trough corresponding to the pin shaft to prevent the crucible from falling into the material receiving trough.
[0016] Preferably, the mold includes a mold body, a sealing plate, and movable front doors; one end of the mold body has a feed inlet; the sealing plate is fixed to the other end of the mold body; a forming groove is formed on the panel of the sealing plate, and the forming groove is connected to the feed inlet; there are two movable front doors, both of which are slidably connected to the sealing plate to open and close the forming grooves; a crucible bottom forming cavity is formed between the movable front doors and the sealing plate. By opening and closing the movable front doors, the crucible bottom can be extruded and formed, and by using the sealing plate as a crucible shaper, crucibles with different structural shapes can be generated.
[0017] Preferably, the mold body is rotatably connected to a stirring blade relative to the inner wall of the feed inlet. The stirring blade stirs the raw materials, ensuring the uniformity of the texture of the final formed crucible.
[0018] Preferably, a protruding nozzle is fixed to the panel on the side of the sealing plate away from the mold body; the sealing plate has a forming groove circumferentially formed relative to the nozzle; and a crucible bottom forming cavity is formed between the nozzle and the movable front door. The nozzle supports the inner bottom wall of the crucible, guiding the crucible forming process.
[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a graphite crucible extrusion molding device, which realizes the assembly line production of crucibles through extrusion molding, cutting and receiving, which can effectively reduce manual input and improve production efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] This utility model embodiment discloses a graphite crucible extrusion molding device, including a mold 1, a cutting part 2 and a receiving part 3;
[0032] One end of the mold 1 is the feeding end and connected to the extruder, and the other end is the forming end; the cutting part 2 includes a support plate 22 and a cutter 25; the panel of the support plate 22 has a slot 23 that corresponds to the forming end of the mold 1; the cutter 25 is slidably connected to the panel of the support plate 22 and its cutting edge faces the slot 23.
[0033] The receiving part 3 and the mold 1 are symmetrically arranged on both sides of the support plate 22. The receiving part 3 includes a support frame and a material receiving trough plate 34. One end of the bottom surface of the material receiving trough plate 34 is hinged to the upper end of the support frame, and the other end faces the support plate 22. A receiving groove is provided above the material receiving trough plate 34 and a corresponding groove opening 23 is provided to receive the extruded crucible.
[0034] like Figure 1 As shown, the mold extrudes the graphite crucible into shape in one step, allowing it to fall through the slot on the support plate into the receiving groove above the material receiving plate.

[0043] In this embodiment, there are multiple cutters 25, which are arranged radially relative to the slot 23 and their cutting edges correspond to the outer wall of the crucible.
[0044] To further optimize the above technical solution, the support frame includes a base plate 31, columns 32 and support columns 33; there are multiple columns 32 and their lower ends are vertically fixed to the top surface of the base plate 31; there are multiple support columns 33, one end of each support column 33 is fixed to the middle of the column 32, and the other end abuts against the bottom surface of one end of the material receiving trough plate 34; the bottom surface of the other end of the material receiving trough plate 34 is hinged to the top of the column 32.
[0045] The material-bearing trough is supported by a cantilever support structure formed by columns and support columns. The material-bearing trough is hinged to the top of the columns. The crucible can be erected by lifting the material-bearing trough.
[0046] In some other specific embodiments, the bottom surfaces of both ends of the material receiving trough can be fixed to the upright column and the support column respectively, and the lower end of the support column can be hinged to the bottom plate. The crucible can be erected by flipping the overall structure formed by the material receiving trough, the upright column and the support column.
[0047] Hydraulic cylinders can be fixed on the base plate to lift the material receiving trough plate, or lifting rings can be installed on the trough wall of the material receiving trough plate to lift the material receiving trough plate using a simple lifting device.
[0048] In some other embodiments, a pin 35 is fixed to the top of the column 32, and the bottom surface of the material receiving trough plate 34 is pinned to the pin 35 through an ear plate.
