Description

Technical Field

[0001] This utility model relates to the field of end cone technology, and in particular to high-strength automotive exhaust system end cone casting molds. Background Technology

[0002] High-strength automotive exhaust system end cone casting molds are specialized molds used to produce end cone components in automotive exhaust systems, and are key equipment in the casting process.

[0003] After the existing end cone casting is completed, most of them rely on manual demolding operations using tools. Specifically, the operator needs to hold simple tools such as pry bars and hammers, and use the lever principle or external force to forcibly separate the solidified end cone casting from the mold. The demolding efficiency is extremely low, and demolding a single casting often takes several minutes or even longer, which is difficult to meet the efficiency requirements of large-scale production. Utility Model Content

[0004] The technical problem to be solved by this utility model is that in the prior art, after the end cone is cast, it is usually necessary to manually use tools such as pry bars and hammers to demold it. Operators use the lever principle or external force to separate the end cone casting from the mold. This method is inefficient, and demolding a casting may take several minutes, which cannot meet the needs of large-scale production. Therefore, we propose a high-strength automotive exhaust system end cone casting mold.

[0005] To achieve the above objectives, this application adopts the following technical solution: a high-strength automotive exhaust system end cone casting mold, including a base, a lower mold base fixedly connected to the top of the base, a forging groove opened on the top of the lower mold base, a slot opened at one end of the lower mold base, a baffle fixedly connected inside the slot, an adjusting groove opened at one end of the baffle, a through slot opened at the top of the inner cavity of the slot, an adjusting rod slidably connected inside the adjusting groove, an arc-shaped pushing block fixedly connected to one end of the adjusting rod, an arc-shaped force-bearing block abutting at the top of the arc-shaped pushing block, a connecting rod fixedly connected to the top of the arc-shaped force-bearing block, a release template fixedly connected to the top of the connecting rod, and the surface of the connecting rod slidably connected to the inside of the through slot.

[0006] Preferably, guide grooves are provided on both sides of the inner cavity of the slot, and guide blocks are fixedly connected to both sides of the arc-shaped force-bearing block, with the surface of the guide block slidingly connected to the inside of the guide groove.

[0007] Preferably, the top of the arc-shaped force-bearing block is fixedly connected to two tension springs, and the top of the tension springs is fixedly connected to the top of the groove cavity.

[0008] Preferably, one end of the baffle is fixedly connected to an extension block, the inside of the extension block is slidably connected to a plug rod, the top of the adjusting rod is provided with a plug hole, the top of the plug rod is fixedly connected to a handle, and the surface of the plug rod is slidably connected to the inside of the plug hole.

[0009] Preferably, a return spring is fixedly connected to the bottom of the handle, and the bottom of the return spring is fixedly connected to the top of the extension block.

[0010] Preferably, the outer diameter of the connector rod is matched with the inner diameter of the connector hole.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, the operator moves an adjusting rod into the groove, causing the adjusting rod to move the arc-shaped pushing block. This causes the arc-shaped pushing block to press against the arc-shaped force block. At this time, the arc-shaped force block will drive the connecting rod and the demolding template to move, allowing the demolding template to move out of the forging groove, thereby completing the demolding of the end cone. The demolding template facilitates the demolding of the end cone, solving the problem of difficult demolding of end cones in the prior art and improving the production efficiency of end cones.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a high-strength automotive exhaust system end cone casting mold, including a base 1, a lower mold base 2 fixedly connected to the top of the base 1, a forging groove 3 opened on the top of the lower mold base 2, a slot 4 opened at one end of the lower mold base 2, a baffle 5 fixedly connected inside the slot 4, an adjusting groove 7 opened at one end of the baffle 5, a through slot 6 opened at the top of the inner cavity of the slot 4, an adjusting rod 8 slidably connected inside the adjusting groove 7, an arc-shaped pushing block 9 fixedly connected to one end of the adjusting rod 8, an arc-shaped force-bearing block 10 abutting the top of the arc-shaped pushing block 9, and a connecting rod 11 fixedly connected to the top of the arc-shaped force-bearing block 10. The top of the connecting rod 11 is fixedly connected to the demolding template 12. The surface of the connecting rod 11 is slidably connected to the inside of the through slot 6. The operator moves the adjusting rod 8 into the slot 4, causing the adjusting rod 8 to drive the arc-shaped pushing block 9 to move. This causes the arc-shaped pushing block 9 to press against the arc-shaped force block 10. At this time, the arc-shaped force block 10 will drive the connecting rod 11 and the demolding template 12 to move, so that the demolding template 12 moves out of the forging slot 3, thereby completing the demolding of the end cone. The demolding template 12 facilitates the demolding of the end cone, solves the problem of difficult demolding of the end cone in the prior art, and improves the production efficiency of the end cone.

[0021] Reference Figure 3 and Figure 4 As shown in this embodiment: guide grooves 13 are provided on both sides of the inner cavity of the slot 4, and guide blocks 14 are fixedly connected to both sides of the arc-shaped force block 10. The surface of the guide block 14 is slidably connected to the inside of the guide groove 13. The guide block 14 is slidably connected to the inside of the guide groove 13. By setting the guide groove 13 and the guide block 14, the arc-shaped force block 10 can be guided, avoiding the arc-shaped force block 10 from deviating during the movement, and improving the stability of the arc-shaped force block 10 when it moves.

[0022] Reference Figure 4 As shown in this embodiment: two tension springs 15 are fixedly connected to the top of the arc-shaped force block 10. The top of the tension springs 15 is fixedly connected to the top of the inner cavity of the slot 4. By setting the tension springs 15, when the arc-shaped force block 10 is squeezed by the arc-shaped push block 9 and moves, the tension springs 15 will deform and stretch. When the arc-shaped push block 9 moves away, the tension springs 15 will use their own elastic restoring force to drive the arc-shaped force block 10 to reset, thereby facilitating the arc-shaped force block 10 to drive the connecting rod 11 and the demolding template 12 to reset, preparing for the next demolding operation, and further improving the production efficiency of the end cone.

[0023] Reference Figure 4 and Figure 5As shown in this embodiment: one end of the baffle 5 is fixedly connected to an extension block 16, and an insertion rod 18 is slidably connected inside the extension block 16. The top of the adjusting rod 8 is provided with an insertion hole 17, and the top of the insertion rod 18 is fixedly connected to a handle 19. The surface of the insertion rod 18 is slidably connected to the inside of the insertion hole 17. When the adjusting rod 8 is pulled out, the position of the adjusting rod 8 can be fixed by moving the insertion rod 18 downward to insert it into the inside of the insertion hole 17, thus preventing the adjusting rod 8 from moving without external force and ensuring the stability and accuracy of the demolding operation.

[0024] Reference Figure 5 As shown in this embodiment: a return spring 20 is fixedly connected to the bottom of the handle 19. The bottom of the return spring 20 is fixedly connected to the top of the extension block 16. The return spring 20 is designed to automatically spring the plug rod 18 back to its original position when the adjustment rod 8 does not need to be fixed, which facilitates the next adjustment operation.

[0025] Reference Figure 4 and Figure 5 As shown in this embodiment: the outer diameter of the plug rod 18 is adapted to the inner diameter of the plug hole 17. Through the sliding connection design between the plug rod 18 and the plug hole 17, not only is the position of the adjusting rod 8 stably fixed, but also the smoothness and convenience of operation are ensured. The outer diameter of the plug rod 18 is perfectly adapted to the inner diameter of the plug hole 17, which effectively prevents the plug rod 18 from shaking or falling off during the plugging process.

[0026] Working principle: By moving the adjusting rod 8 into the groove 4, the operator moves the arc-shaped pushing block 9, causing it to press against the arc-shaped force-bearing block 10. This, in turn, causes the connecting rod 11 and the demolding template 12 to move, allowing the demolding template 12 to move out of the forging groove 3, thus completing the demolding of the end cone. The demolding template 12 facilitates demolding of the end cone, solving the problem of difficult demolding of end cones in existing technologies and improving the production efficiency of end cones. The guide block 14 is slidably connected to the guide groove. Inside 13, guide grooves 13 and guide blocks 14 guide the arc-shaped force block 10, preventing it from shifting during movement and improving its stability. A tension spring 15 is provided; when the arc-shaped force block 10 is compressed by the arc-shaped push block 9, the spring deforms and stretches. When the arc-shaped push block 9 moves away, the spring uses its elastic restoring force to reset the arc-shaped force block 10, facilitating its movement. The connecting rod 11 and the demolding template 12 are reset to prepare for the next demolding operation, further improving the production efficiency of the end cone. The use of high-strength alloy steel significantly improves the hardness and wear resistance of the demolding template 12, ensuring that it maintains good shape and precision during long-term, high-intensity demolding operations, reducing mold failure caused by wear, and extending the service life of the mold. When the adjusting rod 8 is pulled out, the position of the adjusting rod 8 can be fixed by moving the connecting rod 18 downwards and inserting it into the connecting hole 17. To prevent the adjusting rod 8 from moving without external force, the stability and accuracy of the demolding operation are ensured. The reset spring 20 automatically returns the plug rod 18 to its original position when the adjusting rod 8 is no longer needed, facilitating the next adjustment operation. The sliding connection design between the plug rod 18 and the plug hole 17 not only achieves stable fixation of the adjusting rod 8 position, but also ensures smooth and convenient operation. The outer diameter of the plug rod 18 perfectly matches the inner diameter of the plug hole 17, effectively preventing the plug rod 18 from shaking or falling off during the insertion process.
