Description

Technical Field

[0001] This utility model relates to the field of casting distributor molding technology, and in particular to a molding die for processing low-pressure casting distributors. Background Technology

[0002] A casting distributor is a device used in the metal casting process to evenly distribute molten metal into various molds. It is widely used in the casting production of metals such as aluminum, zinc, and lead. A casting distributor is a device used to evenly distribute molten metal from a smelting furnace or tundish into multiple molds. It usually consists of a feed inlet, a distribution chamber, a discharge outlet, and related control devices, and can adjust the flow rate and velocity of the molten metal as needed.

[0003] The conventional casting distributor is a low-pressure casting distributor. During the production process, the casting distributor is cast using a molding die. During the casting process, the molten metal is added into the molding die. Because the air in the die cannot be discharged in time, air bubbles are easily adsorbed on the inner wall of the cavity, resulting in air bubbles and voids in the cast distributor after casting, which affects the quality of the casting distributor. To address this, a molding die for processing low-pressure casting distributors is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a molding die for processing low-pressure casting distributors, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A molding die for processing a low-pressure casting distributor includes a lower die and an upper die. The lower die has a distributor cavity and an operating hole. A drive shaft is rotatably mounted in the operating hole, and a bottom striking assembly is mounted on the drive shaft. Two side shafts are rotatably mounted in the operating hole, located on both sides of the lower die. A transmission assembly is provided between the drive shaft and the side shafts. A side plate is fixedly mounted on one side of the lower die, and a rotating plate is rotatably mounted on the bottom of the side plate. A side striking assembly is provided on one side of the rotating plate, and a striking drive assembly is provided between the side shaft and the rotating plate.

[0007] Preferably, the bottom striking assembly includes multiple annular blocks fixedly sleeved on the drive shaft, with a rubber belt fixedly installed on the side of each annular block and a striking head fixedly installed on one side of the rubber belt.

[0008] Preferably, the striking head has a metal ball inside and a rubber sleeve outside, with one end of the drive shaft extending outside the lower mold and a rotating handle fixedly installed thereon.

[0009] Preferably, the transmission assembly includes a transmission belt disposed between the drive shaft and the side shaft, and the transmission belt is a synchronous belt.

[0010] Preferably, the side striking assembly includes a side striking block fixedly installed on one side of the rotating plate, the side striking block being in contact with one side of the lower mold, and a tension spring being fixedly installed between the rotating plate and the side of the lower mold.

[0011] Preferably, the striking drive assembly includes a fixed sleeve fixedly sleeved on the side shaft, and a drive plate is fixedly installed on the outer side of the fixed sleeve, the drive plate being adapted to the rotating plate.

[0012] Preferably, a rotating roller is rotatably mounted on the drive plate, and the rotating roller is adapted to the rotating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the forming mold for processing the low-pressure casting distributor is equipped with a bottom striking component. When the handle is rotated during casting, the striking head can continuously strike the bottom of the lower mold, realizing vibration transmission from the bottom, which can effectively expel air from the molten metal. The striking head is set in multiple positions to increase the vibration frequency.

[0014] The transmission component is designed to drive the side shaft to rotate. The striking component, after the rotating roller rotates, can drive the side striking block to strike the side of the lower mold, realizing the striking vibration from the side. The lower mold is continuously struck and vibrated from the bottom and the side. The vibration is transmitted in multiple directions, which can effectively remove air bubbles in the casting solution and ensure the quality of the casting after the casting distributor is formed.

Detailed Implementation

[0020] 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.

[0021] Example: Refer to Figure 1-4 A molding die for processing a low-pressure casting distributor includes a lower die 1 and an upper die 2. The lower die 1 is provided with a distributor cavity 3. The upper die 1 to be cast is closed with the lower die 2. The upper die 2 is provided with a pouring port (not shown in the figure) for pouring molten metal. The lower die 1 is provided with an operating hole 18. A drive shaft 4 is rotatably installed in the operating hole 18. A bottom striking component is provided on the drive shaft 4. Two side shafts 9 are rotatably installed in the operating hole 18. The side shafts 9 are located on both sides of the lower die 1. A transmission component is provided between the drive shaft 4 and the side shafts 9. A side plate 11 is fixedly installed on one side of the lower die 1. A rotating plate 12 is rotatably installed on the bottom of the side plate 11. A side striking component is provided on one side of the rotating plate 12. A striking drive component is provided between the side shafts 9 and the rotating plate 12.

[0022] Specifically, the bottom striking assembly includes multiple annular blocks 6 fixedly sleeved on the drive shaft 4. A rubber belt 7 is fixedly installed on the side of the annular block 6, and a striking head 8 is fixedly installed on one side of the rubber belt 7. One end of the drive shaft 4 extends to the outside of the lower mold 1 and is fixedly installed with a rotating handle 5. During the pouring process, the worker holds the rotating handle 5 and rotates it, which drives the drive shaft 4 to rotate, thereby driving the striking head 8 on the bottom striking assembly to rotate. During the rotation, the striking head 8 can continuously strike the bottom of the lower mold 1, which can achieve striking vibration from the bottom. After the vibration is transmitted from the bottom, it can effectively expel the air in the molten metal. The striking head 8 is set in multiple positions. After the drive shaft 4 rotates one revolution, it can strike the bottom of the lower mold 1 multiple times. The vibration frequency is high. The striking head 8 has a metal ball inside and a rubber sleeve outside. The metal ball inside can ensure the force of the striking, and the rubber sleeve can prevent hard contact from damaging the mold.

[0023] Specifically, the transmission assembly includes a transmission belt 10 disposed between the drive shaft 4 and the side shaft 9. The transmission belt 10 is a synchronous belt. The transmission assembly is configured such that the transmission belt 10 on the transmission assembly can transmit power and drive the side shaft 9 to rotate.

[0024] Specifically, the side striking assembly includes a side striking block 13 fixedly installed on one side of the rotating plate 12. The side striking block 13 contacts one side of the lower mold 1. A tension spring 14 is fixedly installed between the rotating plate 12 and the side of the lower mold 1. The striking drive assembly includes a fixed sleeve 15 fixedly sleeved on the side shaft 9. A drive plate 16 is fixedly installed on the outside of the fixed sleeve 15. The drive plate 16 is adapted to the rotating plate 12. A rotating roller 17 is rotatably installed on the drive plate 16. The rotating roller 17 is adapted to the rotating plate 12. After the side shaft 9 rotates, it drives the fixed sleeve on the striking drive assembly. When the fixed sleeve 15 rotates, it drives the rotating roller 17 to move. When the rotating roller 17 contacts the rotating plate 12, it will drive the rotating plate 12 to rotate outward, and the tension spring 14 will be stretched. When the rotating roller 17 is separated from the rotating plate 12, it will be reset under the elastic force of the tension spring 14. At this time, the side striking block 13 strikes the side of the lower mold 1, realizing the striking vibration from the side. It can continuously strike and vibrate the lower mold 1 from the bottom and the side. The vibration transmission direction is multiple, which can effectively remove air bubbles in the casting solution and ensure the quality of the casting distributor after casting.

[0025] In use: Under normal conditions, when the casting distributor is used, after the upper mold 1 and the lower mold 2 are closed, the molten metal is poured. The operator turns the handle 5 to drive the drive shaft 4 to rotate, which in turn drives multiple striking heads 8 to rotate and strike the bottom of the lower mold 1. This can achieve striking vibration from the bottom. After the vibration is transmitted, it can effectively remove air from the molten metal. The striking heads 8 are set in multiple positions and have a high vibration frequency. Under the transmission action of the transmission belt 10, the side shaft 9 is driven to rotate, which in turn drives the rotating roller 17 to move. When the rotating roller 17 rotates, it can drive the side striking block 13 to strike the side of the lower mold 1, achieving striking vibration from the side. The lower mold 1 is continuously struck and vibrated from the bottom and the side. The vibration is transmitted in multiple directions, which can effectively remove air bubbles in the casting solution, ensure the quality of the casting after the casting distributor is formed, and is easy to use.
