Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and more specifically to a forming equipment for processing automotive couplings. Background Technology

[0002] Die casting of automotive couplings is a highly efficient and precise manufacturing method, especially suitable for the mass production of lightweight materials such as aluminum alloys. Its characteristic is that high pressure is applied to molten metal in the cavity of the mold to form a product of the required shape. After the metal solidifies, the part can be removed from the mold and then processed (such as cutting, grinding or polishing) to obtain the final product.

[0003] Existing die-casting equipment typically employs a continuously curved cooling pipe design when cooling the molten metal inside the mold base. The coolant is injected from one end and discharged from the other. However, there is a significant temperature difference between the inflow and outflow ends of the coolant, and this temperature difference becomes more pronounced as the area of ​​the die-cast automotive coupling increases, which can easily have an adverse effect on the molding quality of the automotive coupling. Summary of the Invention

[0004] The purpose of this invention is to provide a forming equipment for processing automotive couplings, in order to solve the problem that the existing technology usually adopts a continuously curved cooling pipe design, in which coolant is injected from one end and discharged from the other end. However, there is a large temperature difference between the inflow and outflow ends of the coolant, and this temperature difference becomes more significant as the area of ​​the die-cast automotive coupling increases, which can easily have an adverse effect on the forming quality of the automotive coupling.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a forming device for processing automotive couplings, comprising a base and two fixed seats mounted on the top of the base, and further comprising:

[0006] A die-casting mechanism, comprising a slide disposed between two fixed seats and a mold seat disposed on the outer wall of the slide on the side opposite to one of the fixed seats;

[0007] The partitioned directional cooling mechanism includes multiple cooling pipes installed inside the mold base, an inner tube installed inside the cooling pipes, and multiple baffles installed sequentially inside the cooling pipes along their length. The baffles are fixedly sleeved on the outside of the inner tubes. A coolant circulation assembly is provided between two adjacent baffles. The coolant circulation assembly includes multiple inlet ports opened on the outer wall of the inner tube and multiple outlet pipes installed on the outer wall of the inner tube.

[0008] Furthermore, a plurality of fixing rods are fixedly connected between the two fixing seats, and the slide is slidably sleeved on the outside of the plurality of fixing rods;

[0009] Another fixed base has multiple hydraulic cylinders installed inside, and the extended ends of the hydraulic cylinders are fixedly connected to the outer wall of the slide.

[0010] Furthermore, the inner tube extends through the cooling pipe and the mold base, and is made of heat-insulating material. One end of the multiple inner tubes is connected to a water inlet pipe, and the other end of the multiple inner tubes is connected to a drain pipe.

[0011] Furthermore, the coolant circulation assembly also includes a mixing pipe disposed inside the inner pipe, one end of the outlet pipe being connected to the mixing pipe, and the mixing pipe being made of heat-insulating material.

[0012] Furthermore, a sealing plate is fixedly sleeved on the outside of the mixing pipe, and the sealing plate is fixed to the inner wall of the inner pipe.

[0013] Furthermore, a venting mechanism is provided between two adjacent partitions. The venting mechanism includes a sealing ring that is slidably sleeved on the outside of the inner tube and a spring that is fixed to the outer wall of the sealing ring near the outlet tube.

[0014] The spring is sleeved on the outside of the inner tube, and the other end of the spring is fixedly connected to the outer wall of the partition.

[0015] The outer wall of the sealing ring abuts against the inner wall of the cooling pipe.

[0016] Furthermore, two limiting blocks are provided between two adjacent partitions. The limiting blocks are fixed to the inner wall of the cooling pipe. One limiting block is located on the left side of the outlet pipe, and the left side of the other limiting block is on the same vertical line as the left side of the inlet.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] Example 1: Please refer to Figure 1 - Figure 4 A forming device for processing automotive couplings includes a base 1 and two fixed seats 2 mounted on top of the base 1, and further includes:

[0028] The die-casting mechanism includes a slide 3 disposed between two fixed seats 2 and a mold seat 4 disposed on the outer wall of the slide 3 on the opposite side of one of the fixed seats 2. A plurality of fixed rods 10 are fixedly connected between the two fixed seats 2, and the slide 3 is slidably sleeved on the outside of the plurality of fixed rods 10. A plurality of hydraulic cylinders 11 are installed inside the other fixed seat 2, and the extended end of the hydraulic cylinder 11 is fixedly connected to the outer wall of the slide 3.

[0029] By controlling the extension of the hydraulic cylinder 11, the slide block 3 is moved to the right along the outside of the fixed rod 10, which in turn drives the mold block 4 on the slide block 3 to move synchronously and merge with the mold block 4 on the right. The injection mechanism injects molten metal into the mold block 4. After the molten metal inside the mold block 4 cools and solidifies, the hydraulic cylinder 11 is controlled to move the slide block 3 to the left, so that the two mold blocks 4 are separated and the formed automotive coupling is taken out.

[0030] The partitioned directional cooling mechanism includes multiple cooling pipes 5 installed inside the mold base 4, an inner tube 6 installed inside the cooling pipes 5, and multiple baffles 7 sequentially installed inside the cooling pipes 5 along their length. The baffles 7 are fixedly sleeved on the outside of the inner tubes 6, and their outer walls are also fixedly connected to the inner walls of the cooling pipes 5. A coolant circulation assembly is provided between adjacent baffles 7. The coolant circulation assembly includes multiple inlet ports 8 opened on the outer wall of the inner tube 6 and multiple outlet pipes 9 installed on the outer wall of the inner tube 6. The inner tube 6 passes through the cooling pipes 5 and the mold base 4, and the inner tube 6 is composed of... Made of heat-insulating material, one end of multiple inner tubes 6 is connected to a water inlet pipe 12, which is connected to a supply device. The part of the water inlet pipe 12 connected to the supply device can be a metal braided hose, which does not affect the movement of the mold base 4 on the slide 3. The other end of multiple inner tubes 6 is connected to a drain pipe 13. The coolant circulation assembly also includes a mixing pipe 14 set inside the inner tubes 6. One end of the outlet pipe 9 is connected to the mixing pipe 14. The mixing pipe 14 is made of heat-insulating material. A sealing plate 15 is fixedly sleeved on the outside of the mixing pipe 14. The sealing plate 15 is fixedly connected to the inner wall of the inner tube 6.

[0031] After the molten metal is injected into the mold base 4, coolant is introduced into each inner tube 6 through the water inlet pipe 12. The coolant inside the inner tube 6 enters each cooling area of ​​the cooling pipe 5 through the inlet port 8 at each position. After the coolant flows through the corresponding cooling area, it is discharged into the mixing pipe 14 through the outlet pipe 9 and then discharged back into the inner tube 6 through the mixing pipe 14. The sealing plate 15 separates the coolant that does not pass through the cooling area from the coolant that does pass through the cooling area. Finally, the coolant flowing out of the inner tube 6 is discharged through the drain pipe 13. By directing the coolant into each cooling area inside the mold base 4, the effect of balanced cooling inside the mold base 4 is achieved, avoiding the problem of large temperature differences in the cooling process of different areas inside the traditional mold base 4 affecting the metal forming quality.

[0032] Example 2: Please refer to Figure 5 This embodiment provides a technical solution based on embodiment 1: a venting mechanism is provided between two adjacent partitions 7. The venting mechanism includes a sealing ring 16 that is slidably sleeved on the outside of the inner tube 6 and a spring 17 that is fixedly connected to the outer wall of the sealing ring 16 near the outlet tube 9. The spring 17 is sleeved on the outside of the inner tube 6, and the other end of the spring 17 is fixedly connected to the outer wall of the partition 7. The outer wall of the sealing ring 16 abuts against the inner wall of the cooling tube 5. Two limiting blocks 18 are also provided between two adjacent partitions 7. The limiting blocks 18 are fixedly connected to the inner wall of the cooling tube 5. One limiting block 18 is located on the left side of the outlet tube 9, and the left side of the other limiting block 18 is on the same vertical line as the left side of the inlet 8.

[0033] After the coolant enters the cooling pipe 5 through the inlet 8, it drives the sealing ring 16 to move to the left, and the spring 17 is compressed. When the sealing ring 16 passes the outlet pipe 9 and abuts against the left limit block 18, the coolant enters the mixing pipe 14 through the outlet pipe 9. After the current automotive coupling is cooled and formed, the injection of coolant into the inner pipe 6 stops. There is still coolant remaining in the cooling pipe 5, and scale may be deposited on the inner wall of the cooling pipe 5. After the injection of coolant into the cooling pipe 5 stops, the spring 17 rebounds and drives the sealing ring 16 to move to the right, discharging the residual coolant in the cooling pipe 5 and scraping off the residual scale on the inner wall of the cooling pipe 5.

[0034] Working principle: By controlling the extension of the hydraulic cylinder 11, the slide 3 moves to the right along the outside of the fixed rod 10, thereby driving the mold base 4 on the slide 3 to move synchronously and merge with the mold base 4 on the right. The injection mechanism injects molten metal into the mold base 4. After the molten metal is injected into the mold base 4, coolant is introduced into each inner tube 6 through the water inlet pipe 12. The coolant inside the inner tube 6 enters each cooling area of ​​the cooling pipe 5 through the inlet port 8 at each position, and drives the sealing ring 16 to move to the left. The spring 17 is compressed. When the sealing ring 16 passes the outlet pipe 9 and abuts against the left limit block 18, the coolant enters the mixing pipe 14 through the outlet pipe 9 and is discharged back into the inner tube 6 through the mixing pipe 14. The setting of the sealing plate 15 makes the coolant enter the mixing pipe 14 through the outlet pipe 9 and then discharge back into the inner tube 6. The coolant that does not pass through the cooling zone is separated from the coolant that does pass through the cooling zone. The coolant that finally flows out through the inner pipe 6 is discharged through the drain pipe 13. By directing the coolant into each cooling zone inside the mold base 4, the effect of balanced cooling inside the mold base 4 is achieved, avoiding the problem of large temperature differences in the cooling process of different areas inside the traditional mold base 4 affecting the metal forming quality. After the current automotive coupling is cooled and formed, the injection of coolant into the inner pipe 6 is stopped. Coolant remains in the cooling pipe 5, and scale may be deposited on the inner wall of the cooling pipe 5. After the injection of coolant into the cooling pipe 5 is stopped, the rebound force of the spring 17 drives the sealing ring 16 to move to the right, discharging the residual coolant in the cooling pipe 5 and scraping off the residual scale on the inner wall of the cooling pipe 5.
