Description

Technical Field

[0001] This invention relates to the field of automotive casting technology, specifically to a high-pressure casting machine for automotive casting and its casting method. Background Technology

[0002] As the global automotive industry accelerates its transformation towards lightweighting, electrification, and intelligentization, higher demands are being placed on the material performance and manufacturing precision of key automotive components. Lightweight alloy castings such as aluminum and magnesium alloys, due to their excellent specific strength and thermal conductivity, are widely used in core components such as engine blocks, transmission housings, wheel hubs, and battery pack housings. High-pressure casting technology, with its advantages of efficient forming, high dimensional accuracy, and superior surface quality, has become the mainstream process for the mass production of automotive castings.

[0003] In traditional high-pressure casting, uneven temperature distribution and incomplete solvent evaporation are prone to occur during the melting process of raw materials. These factors can lead to stress concentration and defects in the casting after cooling and solidification, thereby reducing the overall quality and reliability of the casting and affecting the performance and service life of the final product.

[0008] Preferably, the bottom of the support base three is fixedly installed on the top of the support block one, and the drive motor is fixedly installed on the top of the support block two.

[0009] Preferably, the heating and storage assembly includes a rotating end cover, a material cylinder is fixedly installed on one side of the rotating end cover, a fixed end cover is rotatably sleeved on the end of the material cylinder away from the rotating end cover, a plurality of heating rods are fixedly installed on the outer side of the fixed end cover, a guide pipe is rotatably connected to the side of the fixed end cover away from the material cylinder, and a pusher plate is slidably installed inside the material cylinder.

[0010] Preferably, the rotating seat is rotatably installed inside one side wall of the protective box, one end of each of the plurality of heating rods is fixedly connected to the inner wall of the protective box, and the end of the push rod away from the output end of the die-casting electric cylinder is fixedly connected to one side of the push plate.

[0011] Preferably, the adjustment assembly includes an adjustment disc, the inside of which is provided with a sleeve ring, a moving groove is provided on one side of the adjustment disc, and a hand handle is fixedly installed on one side of the adjustment disc.

[0012] Preferably, a threaded sleeve is fixedly installed inside the hand handle, and a threaded rod is threadedly connected inside the threaded sleeve. A rotating cap is fixedly installed at one end of the threaded rod, and a fastening friction head is fixedly installed at the other end of the threaded rod. The fastening friction head is slidably installed inside the moving groove.

[0013] Preferably, the adjusting disc is rotatably mounted on one side of the protective box, and the guide tube is fixedly mounted on the inner side of the sleeve ring.

[0014] A casting method using a high-pressure casting machine for automotive casting includes the following steps:

[0015] S1: First, rotate the adjusting disc by hand to rotate the guide tube so that the opening of the guide tube faces upward. Then, rotate the rotating cap to rotate the threaded rod inside the threaded sleeve, so that the fastening friction head moves inside the moving groove and comes into contact with one side of the protective box to fix the position of the guide tube. Then, add the die-casting material into the barrel through the guide tube. After that, the heating rod can be activated to heat and melt the die-casting material inside the barrel.

[0016] S2: Then the drive motor can be started. The output end of the drive motor can drive the drive wheel to rotate, which in turn drives the transmission wheel to rotate through the transmission belt, thereby causing the rotating cylinder to rotate. The rotating end cover is driven to rotate through the rotating seat, which in turn drives the material cylinder to rotate, making the heating effect of the heating rod on the material cylinder more uniform and melting the die-casting raw materials inside the material cylinder more quickly.

[0017] S3: Then, the rotating cap can be rotated to drive the threaded rod to rotate inside the threaded sleeve, thereby moving the fastening friction head inside the moving groove, so that the fastening friction head is away from the protective box. Then, the adjustment disc can be rotated by hand to change the orientation of the guide tube as needed. After that, the die-casting electric cylinder can be started. The output end of the die-casting electric cylinder can push the push rod to move, thereby pushing the push plate to move inside the barrel, squeezing the die-casting material inside the barrel, so that the die-casting material is squeezed out through the guide tube to realize the subsequent casting of automotive parts.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the output end of the drive motor can drive the barrel to rotate. On the one hand, it can make the die casting raw material inside the barrel continuously tumble and mix, so that the heat generated by the heating rod is more evenly distributed in the raw material, avoiding local overheating or insufficient melting of the raw material, greatly improving the heating efficiency, making the heating effect of the heating rod on the barrel more uniform, and melting the die casting raw material inside the barrel more quickly. On the other hand, the uniform rotation helps to improve the fluidity of the die casting raw material, creating favorable conditions for the subsequent extrusion molding stage.

[0019] The output end of the die-casting electric cylinder can push the push rod to move, thereby pushing the pusher plate to move inside the barrel, squeezing the die-casting material inside the barrel, so that the die-casting material is squeezed out through the guide tube, realizing the subsequent casting of automotive parts. The guide tube plays a guiding and shaping role in this stage. Its outlet shape and size are precisely processed according to the design requirements of automotive parts to ensure that the extruded die-casting material can form the required shape and size.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6This invention provides a technical solution: a high-pressure casting machine for automotive casting, comprising a support base plate 1, a support block 2 fixedly mounted on the top of the support base plate 1, a support block 3 fixedly mounted on the top of the support base plate 1, a drive assembly mounted on the top of the support blocks 2 and 3, a support pad 6 fixedly mounted on the top of the support base plate 1, a protective box 5 fixedly mounted on the top of the support pad 6, a heating and material storage assembly installed inside the protective box 5, an adjustment assembly mounted on one side of the protective box 5, and the top of the support block 3... The unit is equipped with a control box 4. The drive assembly includes a drive motor 11, a rotating cylinder 18, and a die-casting electric cylinder 13. A drive wheel 20 is fixedly mounted on the output end of the drive motor 11. A transmission belt 12 is sleeved on the outer side of the drive wheel 20. A transmission wheel 16 is sleeved on the inner side of the end of the transmission belt 12 away from the drive wheel 20. The rotating cylinder 18 is fixedly mounted inside the transmission wheel 16. A rotating seat 27 is fixedly mounted on one end of the rotating cylinder 18. A push rod 15 is fixedly mounted on the output end of the die-casting electric cylinder 13. The outer side of the rotating cylinder 18 is rotated... The rotating cylinder 18 is equipped with a support base 10. A support base 2 17 is rotatably mounted on the outside of the rotating cylinder 18. The bottoms of both support base 10 and support base 2 17 are fixedly mounted on the top of support block 2. A support base 3 14 is fixedly mounted on one side of the die-casting electric cylinder 13. The push rod 15 is located inside the rotating cylinder 18. The bottom of support base 3 14 is fixedly mounted on the top of support block 2. The drive motor 11 is fixedly mounted on the top of support block 2 3. The heating and storage assembly includes a rotating end cover 26. A material cylinder 28 is fixedly mounted on one side of the rotating end cover 26. A fixed end cover 25 is rotatably fitted to the end of the material cylinder 28 away from the rotating end cover 26. Multiple heating rods 24 are fixedly installed on the outside of the fixed end cover 25. A guide pipe 9 is rotatably connected to the side of the fixed end cover 25 away from the material cylinder 28. A pusher plate 29 is slidably installed inside the material cylinder 28. A rotating seat 27 is rotatably installed inside the side wall of one side of the protective box 5. One end of each of the multiple heating rods 24 is fixedly connected to the inner wall of the protective box 5. The end of the push rod 15 away from the output end of the die-casting electric cylinder 13 is fixedly connected to one side of the pusher plate 29.

[0029] The working principle of the above technical solution is as follows: Die-casting raw materials are added into the cylinder 28 through the guide pipe 9 to prepare for the subsequent heating and melting process. Then, the heating rod 24 can be activated to heat and melt the die-casting raw materials inside the cylinder 28. The power and heating temperature of the heating rod 24 can be precisely adjusted according to the characteristics of different die-casting raw materials and process requirements. During the heating process, the heating rod 24 works continuously and stably, gradually increasing the temperature inside the cylinder 28. As the temperature rises, the die-casting raw materials begin to undergo physical changes, gradually changing from a solid to a liquid state. To ensure that the raw materials melt completely and the temperature is uniform, the layout of the heating rod 24 is carefully designed to cover all key parts of the cylinder, avoiding local overheating or undercooling, and ensuring that the raw materials complete the melting process under optimal temperature conditions. Afterward, the drive motor 11 can be activated. The output of the drive motor 11 can drive the drive wheel 20 to rotate, which in turn drives the drive wheel 16 to rotate via the transmission belt 12, thereby rotating the rotating cylinder 18. The rotating seat 27 then drives the rotating cylinder 18 to rotate. The rotating end cap 26 drives the barrel 28 to rotate. On the one hand, this allows the die-casting material inside the barrel 28 to continuously tumble and mix, making the heat generated by the heating rod 24 more evenly distributed in the material, avoiding local overheating or incomplete melting, greatly improving heating efficiency, and making the heating effect of the heating rod 24 on the barrel 28 more uniform and faster to melt the die-casting material inside the barrel 28. On the other hand, uniform rotation helps to improve the fluidity of the die-casting material, creating favorable conditions for the subsequent extrusion molding stage. Then, the die-casting electric cylinder 13 is started, and the output end of the die-casting electric cylinder 13 can push the push rod 15 to move, thereby pushing the pusher plate 29 to move inside the barrel 28, extruding the die-casting material inside the barrel 28, so that the die-casting material is extruded through the guide tube 9 to realize the subsequent casting of automotive parts. The guide tube 9 plays a guiding and shaping role in this stage. Its outlet shape and size are precisely processed according to the design requirements of automotive parts to ensure that the extruded die-casting material can form the required shape and size.

[0030] In another implementation scheme, such as Figures 1-6 As shown, the adjustment assembly includes an adjustment disc 19, with a sleeve ring 21 inside the adjustment disc 19. A moving groove 22 is provided on one side of the adjustment disc 19. A hand handle 7 is fixedly installed on one side of the adjustment disc 19. A threaded sleeve 31 is fixedly installed inside the hand handle 7. A threaded rod 30 is threadedly connected inside the threaded sleeve 31. A rotating cap 8 is fixedly installed at one end of the threaded rod 30. A fastening friction head 23 is fixedly installed at the other end of the threaded rod 30. The fastening friction head 23 is slidably installed inside the moving groove 22. The adjustment disc 19 is rotatably installed on one side of the protective box 5. The guide tube 9 is fixedly installed inside the sleeve ring 21.

[0031] When feeding material, the adjusting disc 19 can be rotated by the hand handle 7, which will rotate the guide tube 9 so that the opening of the guide tube 9 faces upward. Rotating the rotating cap 8 will rotate the threaded rod 30 inside the threaded sleeve 31, causing the fastening friction head 23 to move inside the moving groove 22. This will cause the fastening friction head 23 to contact one side of the protective box 5, fixing the position of the guide tube 9. When discharging material, rotating the rotating cap 8 will rotate the threaded rod 30 inside the threaded sleeve 31, causing the fastening friction head 23 to move inside the moving groove 22, moving it away from the protective box 5. Then, rotating the adjusting disc 19 by the hand handle 7 will change the orientation of the guide tube 9 as needed. Finally, rotating the rotating cap 8 will rotate the threaded rod 30 inside the threaded sleeve 31, causing the fastening friction head 23 to move inside the moving groove 22, contacting one side of the protective box 5, fixing the position of the guide tube 9.

[0032] A casting method using a high-pressure casting machine for automotive casting includes the following steps:

[0033] S1: First, rotate the adjusting disc 19 by turning the handle 7, thereby driving the guide tube 9 to rotate, so that the opening of the guide tube 9 faces upward. Then, rotate the rotating cap 8, driving the threaded rod 30 to rotate inside the threaded sleeve 31, thereby causing the fastening friction head 23 to move inside the moving groove 22, so that the fastening friction head 23 abuts against one side of the protective box 5, fixing the position of the guide tube 9. Then, add the die-casting material into the material cylinder 28 through the guide tube 9. After that, the electric heating rod 24 can be activated to heat and melt the die-casting material inside the material cylinder 28.

[0034] S2: Then the drive motor 11 can be started. The output end of the drive motor 11 can drive the drive wheel 20 to rotate, which in turn drives the transmission wheel 16 to rotate through the transmission belt 12, thereby causing the rotating cylinder 18 to rotate. The rotating end cover 26 is driven to rotate through the rotating seat 27, thereby causing the material cylinder 28 to rotate. This makes the heating effect of the heating rod 24 on the material cylinder 28 more uniform and melts the die-casting material inside the material cylinder 28 more quickly.

[0035] S3: Then, the rotating cap 8 can be rotated to drive the threaded rod 30 to rotate inside the threaded sleeve 31, thereby causing the fastening friction head 23 to move inside the moving groove 22, so that the fastening friction head 23 is away from the protective box 5. Then, the adjusting disc 19 can be rotated by the hand handle 7 to change the orientation of the guide tube 9 as needed. Then, the die-casting electric cylinder 13 is started. The output end of the die-casting electric cylinder 13 can push the push rod 15 to move, thereby pushing the pusher plate 29 to move inside the material cylinder 28, squeezing the die-casting material inside the material cylinder 28, so that the die-casting material is squeezed out through the guide tube 9 to realize the subsequent casting of automotive parts.

[0036] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
