Technical Field

[0001] The utility model belongs to the technical field of vertical extruder equipment, in particular to a vertical extruder which is convenient for changing molds. Background Art

[0002] It is very troublesome to replace the mold of a traditional vertical extruder. Since the mold is generally fixed to the extruder head with 8-10 bolts, it needs to be manually disassembled before the mold can be replaced. The whole process is time-consuming and laborious. Although the mold is not replaced frequently during normal production, for new product development or small batch proofing according to customer requirements, the existing method of replacing the mold is too cumbersome, and technicians are often required to be stationed, resulting in waste of manpower and increased costs. In addition, due to the clutter in some production workshops, the mold is easily lost during the replacement and turnover process, resulting in economic losses and delays in production. Therefore, there is a certain market demand for designing a vertical extruder with a simple structure, which can carry multiple molds at the same time and can quickly switch the mold without disassembling the head of the extruder. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to better understand the present invention, Figures 1 to 7The implementation modes of the present utility model will be explained in detail.

[0021] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The "front, back, left, right, up, down" directions are used as the reference. In addition, the molds in this article refer to the fixed mold and movable mold on the flat forging machine.

[0022] The utility model discloses a vertical extruder which is convenient for changing molds. Figure 1 and Figure 2 As shown in the figure, it includes an extruder body 1 and a mold 2 in the prior art. A base bracket 101 is arranged at the bottom of the extruder body 1, and a vertical extrusion cylinder 3 is arranged on the extruder body. In addition, the vertical extruder also includes a newly designed turntable 4, an adjustment gear 5 and an adjustment rod 6. Figures 1 to 7 As shown in , a turntable 4 is rotatably arranged on the extruder body 1, an extrusion head 301 is arranged at the bottom end of the extrusion barrel 3, an opening slot 302 cooperating with the turntable 4 is arranged on the extrusion head 301, a turntable gear 401 is arranged at the bottom of the turntable 4, and an adjustment gear 5 meshing with the turntable gear 401 is arranged on the extruder body 1. In order to save effort, the diameter of the turntable gear 401 is larger than the adjustment gear 5. A plurality of mold grooves 402 cooperating with the extrusion barrel 3 are arranged in an axial rotation array on the turntable 4, and a mold 2 is disassembled and arranged in the mold groove 402. An insertion end 501 is arranged at the bottom of the adjustment gear 5, and an insertion slot 502 cooperating with the adjustment rod 6 is arranged on the insertion end 501. In order to facilitate the placement of the adjustment rod 6, a placement rack 102 cooperating with the adjustment rod 6 is arranged on the extruder body 1.

[0023] like Figures 1 to 3 As shown in , the vertical extruder also includes a locking nut 7. The locking nut 7 is rotatably arranged on the extrusion barrel 3 located above the opening groove 302, and the locking nut 7 is provided with a nut insertion groove 701 that cooperates with the adjustment rod 6. In order to ensure the sealing between the opening groove 302 and the rotating disk 4, a sealing rubber ring 702 is arranged at the bottom of the locking nut 7.

[0024] like Figure 1 , Figure 5 and Figure 6 As shown in , the mold groove 402 is detachably connected to the mold by a clamping method. The mold groove 402 is a step groove, and a limit clamping groove 4021 is arranged in the mold groove 402. Each mold 2 is provided with a limit clamping block 201 that cooperates with the limit groove 4021.

[0025] In order to prevent the rotating disk 4 from deforming due to the force applied from the top during long-term use, thereby causing sealing problems with the opening groove 302, as shown in FIG. Figures 1 to 3As shown in , a limiting ring 403 is disposed on the outer ring of the turntable 4 , and a turntable limiting block 3021 cooperating with the limiting ring 403 is disposed in the opening groove 302 .

[0026] The use and principle of the utility model are as follows: when it is necessary to switch the mold 2, the adjusting rod 6 is inserted into the nut insertion groove 701, and the locking nut 7 is reversed to make it move upward, so that the sealing rubber ring 702 is separated from the top surface of the turntable 4 and their contact state is released. Then the adjusting rod 6 is pulled out and inserted into the insertion groove 502 of the adjusting gear 5, and the turntable 4 is driven to rotate by rotating the adjusting gear 5, so that the mold 2 to be switched is roughly aligned with the axis of the extrusion cylinder 3. Finally, the adjusting rod 6 is pulled out and reinserted into the nut insertion groove 701, and the locking nut 7 is rotated forward to make it move downward and lock it, so that the sealing rubber ring 702 is abutted against the top surface of the turntable 4 to achieve sealing, and the switching of the mold 2 is completed. When it is necessary to replace the mold 2 on the turntable 4, the bottom of the mold 2 to be replaced is supported by hand and rotated, so that the limit block 201 matched with the limit groove 4021 is misaligned, and then the mold 2 is lifted up and removed by hand to complete the disassembly of the mold 2, and then when replacing a new mold 2, the above steps are reversed.
