Description

Technical Field

[0001] This utility model relates to the field of casting technology, and in particular to a multi-station casting device for casting production. Background Technology

[0002] Casting is a process in which molten metal or non-metallic materials are poured into a mold under gravity or pressure, and after cooling and solidification, they form parts of the desired shape and size. This process includes steps such as mold preparation, material melting, pouring, demolding, and subsequent cleaning and processing. Casting can be classified according to its molten state as solidification casting and pressure casting; according to its forming method as sand casting and metal mold casting; and according to the metallic material as cast iron parts and cast steel parts.

[0003] The existing patent application CN202321030670.9 proposes a casting device for a vertical ductile iron casting mold. Although it disperses the molten metal by using the centrifugal force generated when the casting mold body rotates, ensuring that the molten metal fills the entire cavity of the casting mold body during casting and avoiding gaps that may easily occur after the molten metal enters the casting mold, thereby improving the casting effect and the quality of the formed metal casting, it can only cast one workpiece at a time. The next workpiece can only be cast after the workpiece in the mold is demolded, resulting in low casting production efficiency. Therefore, this application proposes a multi-station casting device for casting production to solve the above problems. Utility Model Content

The connecting support plate is installed at the upper end of the piston rod of the lifting cylinder. A casting guide device is fixedly installed at the inner end of the connecting support plate. The casting guide device consists of a funnel body and a connecting guide pipe. The connecting guide pipe is installed at the lower end of the funnel body.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a multi-station casting device for casting production includes a bottom drive housing 1. A rotary worktable 5 is fixedly installed at the upper end of the bottom drive housing 1. Several casting molds 6 are fixedly installed at the upper end of the rotary worktable 5. A lifting bracket 2 is fixedly installed at one end of the bottom drive housing 1. The lifting bracket 2 consists of a Z-shaped support frame 7, a lifting cylinder 8, and a connecting support plate 9. The lifting cylinder 8 is installed at the upper end of the Z-shaped support frame 7, and the connecting support plate 9 is installed at the upper end of the piston rod of the lifting cylinder 8. A casting guide device 3 is fixedly installed at the inner end of the connecting support plate 9. The casting guide device 3 consists of a funnel body 10 and a connecting guide pipe 11. The connecting guide pipe 11 is installed at the lower end of the funnel body 10. A buffer guide device 4 is sleeved on the connecting guide pipe 11. The buffer guide device 4 consists of a mounting fixing ring 12, a buffer spring 13, a mounting moving ring 14, and a buffer guide pipe 15. The buffer spring 13 is installed at the lower end of the mounting fixing ring 12, and the mounting moving ring 14 is installed at the lower end of the buffer spring 13. At the lower end, the buffer guide pipe 15 is installed at the lower end of the installation moving ring 14. During casting production, the lifting bracket 2 can be activated, so that the buffer guide pipe 15 on the buffer guide device 4 is inserted into the pouring port of the casting mold 6. Then, molten metal is poured into the casting guide device 3. The molten metal then flows into the casting mold 6 through the casting guide device 3 and the buffer guide device 4. After casting is completed, the pouring of molten metal into the casting guide device 3 is stopped, and then the lifting bracket 2 is used to buffer the flow. The flow guiding device 4 is reset upward, thereby disengaging the buffer flow guiding device 4 from the pouring port of the casting mold 6. Then, the bottom drive box 1 is activated, thereby driving the rotating worktable 5 and the casting mold 6 to rotate. This causes the casting mold 6 containing molten metal to move away from below the casting flow guiding device 3 and the buffer flow guiding device 4, and the casting mold 6 without molten metal to move below the casting flow guiding device 3 and the buffer flow guiding device 4. The above steps can then be repeated for casting, ultimately achieving continuous casting of the casting.

[0021] Therefore, by setting up a multi-station casting device consisting of a bottom drive box 1, a rotary worktable 5, and multiple casting molds 6, the casting of multiple castings can be completed at one time, thereby improving the efficiency of casting production. By setting up a lifting bracket 2 and a casting guide device 3, the molten metal can be smoothly introduced into the casting mold 6, thereby reducing the spillage of molten metal and thus reducing resource waste. By setting up a buffer guide device 4, the collision between the casting guide device 3 and the casting mold 6 can be avoided, and the collision force on the casting mold 6 can be reduced, thereby reducing the probability of damage to the casting mold 6.

[0022] Specifically, the rotary table 5 is fixedly mounted on the output shaft of the bottom drive housing 1, and the casting mold 6 is fixedly mounted on the upper end of the rotary table 5 by bolts. When the bottom drive housing 1 is started, the output shaft of the bottom drive housing 1 will drive the rotary table 5 to rotate, and the rotary table 5 will drive the casting mold 6 on it to rotate.

[0023] Specifically, the Z-shaped support frame 7 on the lifting bracket 2 is fixedly installed at one end of the bottom drive housing 1 by bolts. The lifting cylinder 8 is fixedly connected to the Z-shaped support frame 7. The connecting support plate 9 is fixedly connected to the piston rod of the lifting cylinder 8 by bolts. The casting guide device 3 is located above the casting mold 6. The funnel body 10 is fixedly installed at one end of the connecting support plate 9. The connecting guide pipe 11 and the funnel body 10 are integrally formed. The mounting ring 12 on the buffer guide device 4 is fixedly sleeved on the connecting guide pipe 11. The buffer spring 13 is sleeved on the connecting guide pipe 11. The buffer spring 13 is fixedly connected to the mounting ring 12 and the mounting moving ring 14. The mounting moving ring 14 on the buffer guide device 4 is movably sleeved on the connecting guide pipe 11. The buffer guide pipe 15 is also movably sleeved on the connecting guide pipe 11. When it is necessary to adjust the buffer guide pipe 15, the buffer guide pipe 15 can be adjusted to adjust the flow rate. When the buffer guide pipe 15 on the flow device 4 is inserted into the pouring port of the casting mold 6, it is necessary to first ensure that the pouring port of the casting mold 6 is coaxial with the buffer guide pipe 15. Then, the lifting cylinder 8 on the lifting bracket 2 is activated. At this time, the piston rod of the lifting cylinder 8 will drive the casting guide device 3 and the buffer guide device 4 to move downward through the connecting support plate 9 until the buffer guide pipe 15 is inserted into the pouring port of the casting mold 6. When the buffer guide pipe 15 collides with the casting mold 6, the buffer guide pipe 15 and the mounting moving ring 14 will move upward, thereby squeezing the buffer spring 13 and thus buffering the impact force. After the casting of molten metal is completed, the lifting cylinder 8 is used to reset the casting guide device 3 and the buffer guide device 4 upward. At this time, under the elastic force of the buffer spring 13, the buffer guide pipe 15 and the mounting moving ring 14 will reset downward.
