Description

Technical Field

[0001] This utility model relates to the field of casting technology, specifically to a double-pouring device for a brake disc vertical line. Background Technology

[0002] As a core component of the automotive braking system, brake disc casting is a production process in which domestic companies generally use clay sand wet mold manual molding and cupola furnace smelting. A few high-end brake discs are produced using coated sand hot core box process or molding line production.

[0003] Traditional molding sand molds typically have only one cavity each, forming a single brake disc after casting. Operators need to cast from each mold individually, and repeatedly flipping the gating cup increases physical exertion. Existing technologies (CN209578049U and CN222552097U) can cast multiple brake discs at once. After cooling, these discs are interconnected via risers (waste material from the gating system), requiring removal after cooling to facilitate subsequent machining. However, removing the risers increases the machining burden. Therefore, we propose a vertically aligned, double-cup casting device for brake discs. Utility Model Content

[0004] The purpose of this invention is to provide a double-pouring device for a vertical line of a brake disc, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-pouring device for a brake disc vertical line, comprising a fixed platform, an adjustment assembly on the top of the fixed platform, the adjustment assembly including a support frame fixedly connected to the top of the fixed platform, a rotating shaft rotatably connected inside the support frame, a worm gear fixedly sleeved on the outer wall of the rotating shaft, a worm gear meshing with the worm, the bottom of the worm rotatably connected to the top of the fixed platform via a bearing, an adjustment knob fixedly connected to the top of the worm, a support platform fixedly connected to the end of the rotating shaft near the worm gear, a bubble level fixedly connected to the top of the support platform, locking blocks fixedly connected to both sides of the bottom of the fixed platform, and a diversion assembly linked to the adjustment assembly on the top of the fixed platform.

[0006] Preferably, the diversion assembly includes a fixed rod that is fixedly sleeved on the outer wall of the rotating shaft, one of the fixed rods having a casting channel fixedly connected to its top, the casting channel having two branch channels fixedly connected to its bottom, and the bottom V-shaped opening of the branch channel being fixedly connected to the top of the other fixed rod.

[0007] Preferably, the bottom of the fixed platform is provided with a mold assembly, the mold assembly includes an upper connecting block inserted into a groove formed between two locking blocks, an upper mold is fixedly connected to the opposite side of the upper connecting block, a lower mold is fastened to the bottom of the upper mold, the bottom of the upper mold and the top of the lower mold together form a cavity, the top of the upper mold has a vertical gate communicating with the cavity, and the top of the upper mold also has a vent communicating with the cavity, and lower connecting blocks are fixedly connected to the adjacent side walls of the two lower molds.

[0008] Preferably, the two branch channels are located on the bottom sides of the casting channel, and the two branch channels are distributed in a V-shape.

[0009] Preferably, the end of the casting channel furthest from the branch channel is higher than the end closest to the branch channel, and the branch channel is used to divert the molten metal liquid in the casting channel.

[0010] Preferably, the bubble level is located above the fixed platform, and the top of the fixed platform is parallel to the bottom of the bubble level.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By adjusting the components and the flow divider, the amount of molten metal entering the two vertical gates can be the same during the casting process, thus enabling the casting of two brake discs at one time. There is no riser or gating system between the two cast brake discs due to the horizontal gating system, so there is no need to cut the two brake discs after cooling, which also facilitates the subsequent sand removal operation.

[0013] The traditional molding sand mold is improved by using upper and lower connecting blocks. Only the outer frame of the upper and lower molds is adjusted without changing the internal structure. This saves the cost of redesigning and manufacturing the mold, reduces the cost of improving the traditional mold, and does not affect the cavity. It increases versatility and the improvement method is simple and easy to implement. With the help of adjustment components and flow diversion components, the two brake discs after molding are independent of each other. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] This utility model provides a technical solution: such as Figures 1-5 The illustrated brake disc vertical line double pouring device includes a fixed platform 1. An adjustment assembly is provided on the top of the fixed platform 1. The adjustment assembly includes a support frame 2 fixedly connected to the top of the fixed platform 1. A rotating shaft 6 is rotatably connected inside the support frame 2. A worm gear 7 is fixedly sleeved on the outer wall of the rotating shaft 6. A worm 8 is meshed with the worm gear 7. The bottom of the worm 8 is rotatably connected to the top of the fixed platform 1 through a bearing. An adjustment knob 9 is fixedly connected to the top of the worm 8. A support platform 10 is fixedly connected to the end of the rotating shaft 6 near the worm gear 7. A bubble level 11 is fixedly connected to the top of the support platform 10. Locking blocks 12 are fixedly connected to both sides of the bottom of the fixed platform 1. A diversion assembly that is linked to the adjustment assembly is also provided on the top of the fixed platform 1.

[0023] like Figure 3 , Figure 4 and Figure 5 As shown, the diversion assembly includes a fixed rod 3 that is fixedly sleeved on the outer wall of the rotating shaft 6. The top of one of the fixed rods 3 is fixedly connected to a casting channel 4, and the bottom of the casting channel 4 is fixedly connected to two branch channels 5. The bottom V-shaped opening of the branch channel 5 is fixedly connected to the top of the other fixed rod 3.

[0024] like Figure 2 , Figure 4 and Figure 5As shown, a mold assembly is provided at the bottom of the fixed platform 1. The mold assembly includes an upper connecting block 13 that is inserted into the groove formed between two locking blocks 12. An upper mold 15 is fixedly connected to the opposite side of the upper connecting block 13. A lower mold 16 is fastened to the bottom of the upper mold 15. The bottom of the upper mold 15 and the top of the lower mold 16 together form a cavity 19. A vertical gate 17 communicating with the cavity 19 is opened on the top of the upper mold 15, and a vent 18 communicating with the cavity 19 is also opened on the top of the upper mold 15. Lower connecting blocks 14 are fixedly connected to the adjacent side walls of the two lower molds 16. Before use, the operator needs to weld the molds in pairs: the two upper molds 15 are welded and fixed by the upper connecting block 13, and the two lower molds 16 are welded and fixed by the lower connecting block 14. Then, molding sand is filled into the upper mold 15 and the lower mold 16 to form a cavity 19, a vertical gate 17, and a vent 18. Before casting, the operator inserts the fixed platform 1 between the two molds through the clamping block 12. Then, the operator judges the level according to the bubble level 11. When the level needs to be adjusted, the adjusting knob 9 is turned so that the worm 8 drives the worm wheel 7 to rotate, which in turn drives the rotating shaft 6 to rotate, so that the casting channel 4 and the branch channel 5 are in a horizontal state. After the operator receives the molten metal through the pouring cup, it is poured into the casting channel 4. Since the casting channel 4 and the branch channel 5 have been adjusted to a horizontal state, the branch channel 5 can evenly distribute the molten metal in the casting channel 4, so that the amount of molten metal entering the two vertical gates 17 is the same, thus completing the effect of double casting in one cup.

[0025] like Figure 1 , Figure 3 and Figure 5 As shown, the two branch channels 5 are located on the bottom sides of the casting channel 4, and the two branch channels 5 are distributed in a V-shape.

[0026] like Figure 3 , Figure 4 and Figure 5 As shown, the end of the casting channel 4 furthest from the branch channel 5 is higher than the end closest to the branch channel 5. The branch channel 5 is used to divert the molten metal liquid in the casting channel 4.

[0027] like Figure 2 , Figure 4 and Figure 5 As shown, the bubble level 11 is located above the fixed platform 1, and the top of the fixed platform 1 is parallel to the bottom of the bubble level 11.

[0028] Working principle: Before use, the operator needs to weld the molds in pairs: the two upper molds 15 are welded and fixed by the upper connecting block 13, and the two lower molds 16 are welded and fixed by the lower connecting block 14. Then, molding sand is filled into the upper molds 15 and the lower molds 16 to form a cavity 19, a vertical gate 17, and a vent 18. Before casting, the operator inserts the fixing platform 1 between the two molds through the clamping block 12. Then, the operator judges the level by the bubble level 11. When the level needs to be adjusted, the adjusting knob 9 is turned so that the worm 8 drives the worm wheel 7 to rotate, which in turn drives the rotating shaft 6 to rotate, so that the casting channel 4 and the branch channel 5 are in a horizontal state. After the operator receives the molten metal through the pouring cup, it is poured into the casting channel 4. Since the casting channel 4 and the branch channel 5 have been adjusted to a horizontal state, the branch channel 5 can evenly distribute the molten metal in the casting channel 4, so that the amount of molten metal entering the two vertical gates 17 is the same, thus completing the effect of double casting in one cup.
