Description

Technical Field

[0001] This invention relates to the field of casting and forging technology, and specifically to a casting and forging combined forming mold system. Background Technology

[0002] To promote the replacement of traditional steel parts with aluminum alloys, most complex aluminum alloy products are often formed using casting or forging processes.

[0003] Due to its high production efficiency, simple forming process, and ability to form complex products, casting technology accounts for approximately 60% of the total aluminum alloy composition in automotive lightweight structural design. Combining casting and forging processes eliminates defects such as porosity, misalignment, and cracks, while also shortening the forming cycle and mitigating the long production time associated with forging alone. This results in products with a dense internal structure, complete flow lines, and improved surface quality, thus enhancing their mechanical properties.

[0004] To facilitate demolding during the forging process, a release agent needs to be placed inside the cavity of the forging die. Currently, most methods involve setting up spraying mechanisms on the upper and lower dies of the forging die to apply the release agent separately. This results in long spraying times and complex positioning of the spraying mechanisms, which can easily affect the die closing process. Summary of the Invention

[0005] The purpose of this invention is to provide a casting and forging combined forming mold system to solve the technical problems in the prior art, which uses a spraying mechanism to spray release agent on the upper and lower molds of the forging forming mold separately, resulting in long spraying time and complex position design of the spraying mechanism, which can easily affect the mold closing operation.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A casting and forging combined forming die system, comprising:

[0008] A forming upper mold and a forming lower mold, and a release agent spraying assembly disposed between the forming upper mold and the forming lower mold, the release agent spraying assembly being used to simultaneously spray release agent onto the forming upper mold and the forming lower mold;

[0009] The release agent spraying assembly includes shifting rods disposed on both sides of the lower forming mold, and a bearing cavity movably installed between the upper ends of the two shifting rods, wherein a bidirectional spray nozzle is installed on the bearing cavity;

[0010] When spraying the release agent, the two nozzles of the bidirectional nozzle are adjusted to face the upper mold and the lower mold respectively, and when the spraying is completed, the two nozzles of the bidirectional nozzle are adjusted to face the upper mold simultaneously to prevent the release agent from overflowing.

[0011] As a preferred embodiment of the present invention, the guide pipe connected to the bidirectional nozzle passes through the upper end of the displacement rod and the bearing cavity. When the bearing cavity rotates around the upper ends of the two displacement rods, the flow of the guide pipe is automatically adjusted by the extrusion mechanism.

[0012] When the shifting rod moves to one end of the cavity of the upper forming mold and the lower forming mold, the bearing cavity is adjusted and rotated until the nozzles of the bidirectional nozzles face the upper forming mold and the lower forming mold respectively. At this time, the guide tube is in an open state, and the release agent is sprayed into the cavity of the upper forming mold and the lower forming mold.

[0013] When the shifting rod moves to the other end of the cavity of the upper forming mold and the lower forming mold, the bearing cavity is adjusted to rotate in the opposite direction to its original state, and the guide tube is squeezed and closed.

[0014] As a preferred embodiment of the present invention, the upper ends of the two displacement rods are provided with circular slots, a hollow cylinder is provided along the arc surface of each circular slot, a first sector plate is provided below the hollow cylinder, a curved extension plate is provided along the arc surface of the first sector plate, and a second sector plate is provided at the end of the curved extension plate.

[0015] The two ends of the bearing cavity are respectively sleeved on the outside of the hollow cylinder and the curved extension plate, and the bearing cavity can rotate around the hollow cylinder and the curved extension plate to adjust the orientation of the bidirectional nozzle.

[0016] As a preferred embodiment of the present invention, a straight panel is provided between the same side of the first sector plate and the second sector plate, the guide tube is disposed on the straight panel, and the guide tube passes through the hollow rings at both ends of the straight panel, so that the lower end of the guide tube is always in close contact with the straight panel.

[0017] As a preferred embodiment of the present invention, the extrusion mechanism includes an extrusion panel disposed on the inner wall of the end of the bearing cavity, the extrusion panel being positioned between the first sector plate and the second sector plate, and the extrusion panel rotating between the first sector plate and the second sector plate when the bearing cavity rotates around the hollow cylinder;

[0018] When the bearing cavity is adjusted to rotate in the opposite direction to its original state, the extrusion panel squeezes and blocks the guide tube to suspend the spraying of the release agent.

[0019] As a preferred embodiment of the present invention, when the bearing cavity is rotated by 90°, the nozzles of the bidirectional nozzles face the upper forming mold and the lower forming mold respectively, and at this time the angle between the side of the extrusion panel used to extrude the guide tube and the plane where the straight panel is located is 90°.

[0020] When the bearing cavity is rotated 90° in the opposite direction, the nozzles of the bidirectional nozzles are all facing the forming upper mold, and at this time the angle between the side of the extrusion panel used to extrude the guide tube and the plane where the straight panel is located is 0°.

[0021] In a preferred embodiment of the present invention, the center of the extrusion panel coincides with the center of the first sector plate, and the centers of the extrusion panel and the first sector plate are located on the central axis of the hollow cylinder. A connecting rod is provided at the center of the first sector plate and the second sector plate, and a cavity sleeve is provided at the center of the extrusion panel. The cavity sleeve is movably mounted on the connecting rod. When the cavity sleeve is rotated so that both nozzles of the bidirectional nozzle are facing upwards, the extrusion panel is exactly in complete contact with the straight panel and completely blocks the guide tube.

[0022] As a preferred embodiment of the present invention, an arc-shaped rack ring is provided on the end side curved surface of the bearing cavity, a linear drive assembly is installed on the displacement rod, and a toothed plate is installed on the output shaft of the linear drive assembly. The linear drive assembly drives the toothed plate to move up and down, and then drives the bearing cavity and the bidirectional nozzle to rotate through the meshing action between the toothed plate and the arc-shaped rack ring.

[0023] As a preferred embodiment of the present invention, the angle between the end of the bidirectional nozzle and the body of the bidirectional nozzle is an obtuse angle, and the end of the bidirectional nozzle faces upward when rotated to a horizontal state, so as to prevent the release agent in the bidirectional nozzle from overflowing.

[0024] In a preferred embodiment of the present invention, the shifting rod is driven by the speed-changing drive assembly to move linearly reciprocally between the upper forming mold and the lower forming mold. By adjusting the rotational speed of the speed-changing drive assembly, the spraying time and spraying amount of the upper forming mold and the lower forming mold are controlled, so that the spraying time of the forming mold for the first use is greater than the spraying time of the forming mold for each forming operation, and the spraying amount of the forming mold for the first use is greater than the spraying amount of the forming mold for each forming operation.

[0025] Compared with the prior art, the present invention has the following advantages:

[0026] The bidirectional nozzle of the present invention can reciprocate between the upper and lower molds of the shaping mold, and can automatically and synchronously spray the release agent onto the upper and lower molds. After the spraying is completed, the bidirectional nozzle is adjusted to a horizontal state to prevent the release agent in the bidirectional nozzle from overflowing.

[0027] Meanwhile, when adjusting the nozzle orientation of the bidirectional nozzles, the squeezing action of the rotating bearing cavity can be used to automatically and in a linked manner control the opening and closing of the mold release agent guide tube. When the nozzles of the bidirectional nozzles are respectively facing the upper and lower molds, the mold release agent guide tube is opened; when both nozzles of the bidirectional nozzles are facing the upper mold, the mold release agent guide tube is closed. This improves the integration of the molding mold system and eliminates the need to add valves to control the opening and closing of the mold release agent guide tube. Attached Figure Description

[0039] 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.

[0040] This invention provides a casting-forging combined forming mold system, wherein the specific steps of the casting-forging combined forming process are as follows: Step 100: Transfer the heated and molten liquid aluminum alloy to a low-pressure crucible, and apply pressure to the low-pressure crucible to make the liquid aluminum alloy continuously flow into the low-pressure casting mold to obtain a linear casting billet; Step 200: Heat the casting billet and the billet bending mold, and use the billet bending mold to press the linear casting billet into a bent billet with the same curvature as the product; Step 300: Keep the bent billet warm and transfer it to the forming mold, and use the forming mold to extrude the bent billet into a formed product with shape details through multiple stamping and forging; Step 400: Trim and punch holes in the formed product, and after trimming and punching, place the formed product into a cooling and shaping mold; Step 500: Perform heat treatment on the aluminum alloy rear control arm formed by casting-forging combined forming to strengthen the shape and performance of the formed product.

[0041] The design of this casting and forging combined process analyzes and controls the parameters of raw materials from melting to casting to forming, trimming and punching to heat treatment, so as to achieve precise control of the product forming process. Since the bent billet needs to be stamped and forged multiple times during the forming process to obtain a formed product with detailed shape, in order to ensure that the formed product obtained by stamping and forging is easy to remove and to avoid the forming die sticking to the product during the stamping and forging process, which would cause the product to move during multiple forgings, it is necessary to spray a release agent on the upper and lower dies of the forming mold before forging each product.

[0042] Therefore, as Figure 1 As shown, the molding die system in this embodiment specifically includes an upper molding die 1 and a lower molding die 2, as well as a release agent spraying assembly 3 disposed between the upper molding die 1 and the lower molding die 2. The release agent spraying assembly 3 is used to spray release agent onto the upper molding die 1 and the lower molding die 2 simultaneously.

[0043] Among them, such as Figure 2As shown, the release agent spraying assembly 3 includes displacement rods 31 disposed on both sides of the lower mold 2, and a bearing cavity 32 movably installed between the upper ends of the two displacement rods 31, with a bidirectional nozzle 33 installed on the bearing cavity 32.

[0044] When spraying the release agent, the two nozzles of the bidirectional nozzle 33 are adjusted to face the upper mold 1 and the lower mold 2 respectively, and when the spraying is completed, the two nozzles of the bidirectional nozzle 33 are adjusted to face the upper mold 1 simultaneously to prevent the release agent from overflowing.

[0045] Furthermore, the angle between the end of the bidirectional nozzle 33 and the body of the bidirectional nozzle 33 is an obtuse angle, and the end of the bidirectional nozzle 33 faces upward when rotated to a horizontal state to prevent the release agent inside the bidirectional nozzle 33 from overflowing.

[0046] In this embodiment, the release agent can be sprayed onto the upper mold 1 and the lower mold 2 simultaneously, eliminating the need to use different nozzles to spray the upper mold 1 and the lower mold 2 in a staggered manner, thus improving spraying efficiency. In addition, after spraying is completed, the bidirectional nozzles 33 are adjusted to face the upper mold 1 simultaneously to prevent the release agent from overflowing and improve safety.

[0047] In addition, such as Figures 3 to 5 As shown, in this embodiment, while adjusting the direction of the bidirectional nozzle 33, the extrusion mechanism 4 can also be activated to automatically adjust the opening and closing of the guide pipe 34. There is no need to use an additional solenoid valve to control the delivery of the release agent, and the mold system has a high degree of integration.

[0048] The guide pipe 34 connected to the bidirectional nozzle 33 passes through the upper end of the shifting rod 31 and the bearing cavity 32. When the bearing cavity 32 rotates around the upper end of the two shifting rods 31, the flow of the guide pipe 34 is automatically adjusted by the extrusion mechanism 4.

[0049] When the shifting rod 31 moves to one end of the cavity of the upper mold 1 and the lower mold 2, the bearing cavity 32 is adjusted and rotated until the nozzles of the bidirectional nozzle 33 are facing the upper mold 1 and the lower mold 2 respectively. At this time, the guide tube 34 is in the open state, and the release agent is sprayed into the cavity of the upper mold 1 and the lower mold 2.

[0050] When the shifting rod 31 moves to the other end of the cavity of the upper forming mold 1 and the lower forming mold 2, the bearing cavity 32 is adjusted to rotate in the opposite direction to the original state, and the guide tube 34 is squeezed and closed.

[0051] Therefore, when spraying is required, the bidirectional nozzle 33 is adjusted to face the upper mold 1 and the lower mold 2 respectively, while the guide tube 34 is adjusted to be in the open state, the bearing cavity 32 is adjusted to rotate in the opposite direction to the original state, and the guide tube 34 is squeezed closed. This establishes a linkage between the delivery of the release agent during the release agent spraying operation and the turning position of the bidirectional nozzle 33, eliminating the need for an additional control system to regulate the delivery of the release agent, thus making the function more stable.

[0052] The specific method for establishing a linkage between the delivery of the release agent and the turning position of the bidirectional nozzle 33 during the release agent spraying operation is as follows:

[0053] Both displacement rods 31 have circular slots at their upper ends. A hollow cylinder 5 is provided on the arc surface of each circular slot. A first sector plate 6 is provided below the hollow cylinder 5. A curved extension plate 7 is provided along the arc surface of the first sector plate 6. A second sector plate 8 is provided at the end of the curved extension plate 7.

[0054] The two ends of the bearing cavity 32 are respectively sleeved on the outside of the hollow cylinder 5 and the curved extension plate 7, and the bearing cavity 32 can rotate around the hollow cylinder 5 and the curved extension plate 7 to adjust the orientation of the bidirectional nozzle 33.

[0055] A straight panel 9 is provided between the same side of the first sector plate 6 and the second sector plate 8. A guide tube 34 is provided on the straight panel 9, and the guide tube 34 passes through the hollow rings 10 at both ends of the straight panel 9, so that the lower end of the guide tube 34 is always in close contact with the straight panel 9.

[0056] The extrusion mechanism 4 includes an extrusion panel 41 disposed on the inner wall of the end of the bearing cavity 32. The extrusion panel 41 is positioned between the first sector plate 6 and the second sector plate 8. When the bearing cavity 32 rotates around the hollow cylinder 5, the extrusion panel 41 rotates between the first sector plate 6 and the second sector plate 8.

[0057] When the bearing cavity 32 is adjusted to rotate in the opposite direction to its original state, the extrusion panel 41 extrudes and blocks the guide tube 34 to suspend the spraying of the release agent.

[0058] In this embodiment, the bearing cavity 32 can rotate around the hollow cylinder 5, thereby adjusting the direction of the bidirectional nozzle 33. In order to ensure that the flow guide 34 can be controlled simultaneously when the bearing cavity 32 rotates, a curved extension plate 7 is provided on the hollow cylinder 5 to facilitate the rotation of the bearing cavity 32. When the bearing cavity 32 rotates, the extrusion panel 41 installed on its inner wall can extrude the flow guide 34 on the first sector plate 6 and the second sector plate 8.

[0059] As a preferred embodiment, the guide tube 34 connected to the bidirectional nozzle 33 is temporarily limited by the straight panel 9. The guide tube 34 is bound tightly to the straight panel 9 by the hollow ring 10. Then, when the bearing cavity 32 is rotated, the guide tube 34 is pressed by the squeezing panel 41 to cut off the flow, or the guide tube 34 is released to supply liquid.

[0060] In this embodiment, when spraying the release agent, the nozzles of the bidirectional spray head 33 need to be adjusted to face the upper mold 1 and the lower mold 2 respectively. When the spraying is completed, the nozzles of the bidirectional spray head 33 need to face upwards. Therefore, in this embodiment, the bidirectional spray head 33 needs to rotate back and forth between 0° and 90°.

[0061] When the bearing cavity 32 is rotated 90°, the nozzles of the bidirectional nozzle 33 face the upper forming mold 1 and the lower forming mold 2 respectively. At this time, the angle between the side of the extrusion panel 41 used to extrude the guide tube 34 and the plane where the straight panel 9 is located is 90°. The extrusion panel 41 releases the guide tube 34 to supply liquid.

[0062] When the bearing cavity 32 is adjusted to rotate 90° in the opposite direction, the nozzles of the bidirectional nozzles 33 are all facing the upper forming mold 1, and at this time the angle between the side of the extrusion panel 41 used to extrude the guide tube 34 and the plane where the straight panel 9 is located is 0°, and the extrusion panel 41 presses the guide tube 34 to cut off the flow.

[0063] Therefore, in this embodiment, the arc angle between the extrusion panel 41, the first sector plate 6, and the second sector plate 8 is not fixed. It is only required that the nozzles of the bidirectional nozzle 33 face the upper forming mold 1 and the lower forming mold 2 respectively. The angle between the side of the extrusion panel 41 used to extrude the guide tube 34 and the plane where the straight panel 9 is located is 90°. In this way, when the nozzle is rotated to face upward, the guide tube 34 can be completely extruded and the flow can be cut off.

[0064] In a preferred embodiment of this implementation, the center of the extrusion panel 41 coincides with the center of the first sector plate 6. The centers of the extrusion panel 41 and the first sector plate 6 are located on the central axis of the hollow cylinder 5. A connecting rod 42 is provided at the center of the first sector plate 6 and the second sector plate 8. A cavity sleeve 43 is provided at the center of the extrusion panel 41. The cavity sleeve 43 is movably mounted on the connecting rod 42. When the cavity sleeve 43 is rotated until both nozzles of the bidirectional nozzle 33 are facing upwards, the extrusion panel 41 is exactly in complete contact with the straight panel 9 and completely blocks the guide pipe 34.

[0065] The radius of the extrusion panel 41 is limited to the radius of the bearing cavity 32, and the radii of the first sector plate 6 and the second sector plate 8 are the radii of the hollow cylinder 5. This limits the center position of the first sector plate 6 and the second sector plate 8 to the setting of the connecting rod 42. The extrusion panel 41 uses the hollow sleeve 43 to rotate around the connecting rod 42. When the hollow sleeve 43 rotates to the point where both nozzles of the bidirectional nozzle 33 are facing upwards, the extrusion panel 41 is exactly in complete contact with the straight panel 9 and completely blocks the guide tube 34.

[0066] As described above, in this embodiment, the rotation direction and angle of the bearing cavity 32 are adjusted by driving the bearing cavity 32 to rotate, thereby adjusting the nozzle orientation of the bidirectional nozzle 33 fixed on the bearing cavity 32. Specifically, the method for adjusting the rotation of the bearing cavity 32 is as follows:

[0067] like Figure 6 As shown, an arc-shaped rack ring 11 is provided on the end side curved surface of the bearing cavity 32, a linear drive assembly 12 is installed on the displacement rod 31, and a toothed plate 13 is installed on the output shaft of the linear drive assembly 12. The linear drive assembly 12 drives the toothed plate 13 to move up and down, and then drives the bearing cavity 32 and the bidirectional nozzle 33 to rotate through the meshing action between the toothed plate 13 and the arc-shaped rack ring 11.

[0068] The shifting rod 31 is pushed by the speed change drive assembly to move linearly and reciprocally between the upper forming mold 1 and the lower forming mold 2. By adjusting the speed of the speed change drive assembly, the spraying time and spraying amount of the upper forming mold 1 and the lower forming mold 2 are controlled so that the spraying time of the forming mold for the first use is greater than the spraying time of the forming mold for each forming operation, and the spraying amount of the forming mold for the first use is greater than the spraying amount of the forming mold for each forming operation.

[0069] When the forming mold is used for the first time, the shifting rod 31 is pushed by the speed change drive assembly to the ends of the upper forming mold 1 and the lower forming mold 2. At this time, the linear drive assembly 12 drives the toothed plate 13 to move upward, pushing the bearing cavity 32 to rotate so that the two nozzles of the bidirectional spray nozzle 33 face the upper forming mold 1 and the lower forming mold 2 respectively. At this time, the shifting speed of the speed change drive assembly is adjusted to the low gear, so that the shifting rod 31 moves between the two ends of the forming cavity for a longer time, requiring the spraying time to last for more than 30 seconds and the amount of release agent sprayed to increase.

[0070] When forming a bent blank each time, a thin, uniform release agent is required to be applied to the inner wall of the forming mold cavity. The shifting rod 31 is moved to the ends of the upper forming mold 1 and the lower forming mold 2 by the speed-changing drive assembly. At this time, the linear drive assembly 12 drives the toothed plate 13 to move upward, pushing the bearing cavity 32 to rotate so that the two nozzles of the bidirectional spray nozzle 33 face the upper forming mold 1 and the lower forming mold 2 respectively. At this time, the shifting speed of the speed-changing drive assembly is adjusted to the high setting, so that the time for the shifting rod 31 to move between the two ends of the forming cavity is shortened and the spraying time is required to be less than 10 seconds.

[0071] After the mold release agent is applied to the cavity of the forming mold, the linear drive assembly 12 moves the toothed plate 13 downward, pushing the bearing cavity 32 to rotate so that both nozzles of the bidirectional spray head 33 are facing the upper forming mold 1.

[0072] Therefore, in this embodiment, the bidirectional nozzle 33 can reciprocate between the upper and lower molds of the shaping mold, and can automatically and synchronously spray the release agent onto the upper mold 1 and the lower mold 2. After the spraying is completed, the bidirectional nozzle 33 is adjusted to a horizontal state to prevent the release agent in the bidirectional nozzle 33 from overflowing.

[0073] Meanwhile, when adjusting the nozzle orientation of the bidirectional nozzle 33, the squeezing action of the rotating bearing cavity 32 can be used to automatically and in a linked manner control the opening and closing of the mold release agent guide tube. When the nozzles of the bidirectional nozzle 33 are respectively facing the upper mold 1 and the lower mold 2, the mold release agent guide tube is opened. When the nozzles of the bidirectional nozzle 33 are both facing the upper mold, the mold release agent guide tube is closed, thereby improving the integration of the molding mold system without the need to add valves to control the opening and closing of the mold release agent guide tube.

[0074] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
