Technical Field

[0001] The present invention relates to the field of manufacturing of multi-leaf transmission parts, and in particular to a die-casting mold for producing multi-leaf transmission parts for new energy vehicles. Background Art

[0002] Multi-leaf transmission parts refer to mechanical devices with multiple blades of special shapes, which transmit power and motion through the synchronous movement of multiple blades to achieve the connection and motion conversion between different parts. With the rapid development of the new energy vehicle industry, multi-leaf transmission parts, as an important component, play an irreplaceable role in ensuring the efficient operation of vehicles.

[0003] Multi-leaf transmission parts are cast by die-casting during production, which requires die-casting molds. For multi-leaf transmission parts with blades tilted at specific angles, traditional die-casting molds are difficult to guarantee product quality and production efficiency. Some manufacturers will choose to add a rotating mechanism or elastic device inside the die-casting mold to assist in the opening and closing action, or introduce a semi-automatic production line with manual participation, and workers will manually adjust the blade angle after the initial molding.

[0004] Both of the above methods have limitations. The former has a high failure rate and high maintenance cost due to its complex structure, while the latter has a low yield, poor quality consistency and a prolonged production cycle due to manual intervention. Summary of the invention

[0005] In order to adapt to the die-casting of blades with specific angles and ensure product quality and production efficiency, the present application provides a die-casting mold for the production of multi-leaf transmission parts for new energy vehicles.

[0016] By adopting the above technical solution, the top mold and the bottom mold are respectively set to correspond to different parts of the multi-leaf transmission part, so that the top and bottom of the multi-leaf transmission part can be accurately formed. The structure of the top mold and the bottom mold makes the mold structure more compact and reasonable, and improves the yield rate.

[0017] Optionally, a plurality of cushion blocks are fixed to one side of the male template close to the core pulling block, and the core pulling block abuts against the cushion blocks.

[0018] By adopting the above technical solution, the setting of the cushion block prevents the core pulling block from directly contacting the male mold plate when moving, reducing the friction between the core pulling block and the male mold plate, and at the same time plays an auxiliary stabilizing role for the core pulling block, ensuring the smooth movement of the core pulling block.

[0031] The following is combined with Figure 1-8 This application is described in further detail.

[0032] The present application embodiment discloses a die-casting mold for the production of multi-leaf transmission parts for new energy vehicles. Figure 1 and Figure 2 A die-casting mold for the production of multi-leaf transmission parts for new energy vehicles is used to produce multi-leaf transmission parts with blades inclined at a specific angle. The specific shape and structure of the multi-leaf transmission parts are as follows: Figure 1 As shown, the cross-sectional diagram is Figure 2 See Figure 3 The die-casting mold includes a fixed mold, a movable mold and a blade clamping unit 5. The fixed mold includes a front supporting plate 1 and a female mold plate 2. The movable mold includes a rear supporting plate 4 and a male mold plate 3. The blade clamping unit 5 is located between the female mold plate 2 and the male mold plate 3. The die-casting mold is sequentially a front supporting plate 1, a female mold plate 2, a blade clamping unit 5, a male mold plate 3 and a rear supporting plate 4.

[0033] Reference Figures 4 to 6The front support plate 1 is used to support the smooth operation of the entire mold system. A gate 11 is provided on the front support plate 1. The gate 11 is connected to a die-casting machine. A gate sleeve 12 is provided on the outside of the gate 11. The gate sleeve 12 is used to connect and fix the gate 11 and the external die-casting machine. A cooling ring 13 is also provided on the outside of the gate sleeve 12 for cooling the gate sleeve 12 and the internal molten metal. A receiving groove 15 is provided on the side of the front support plate 1 close to the mother mold plate 2. A guide column 14 is provided in the receiving groove 15. The guide column 14 is connected to the gate 11. A placement groove 21 is provided on the side of the mother mold plate 2 close to the front support plate 1. A diverter block 22 is provided in the placement groove 21. The diverter block 22 is connected to the guide column 14. The pouring gate 11, the guide column 14 and the diverter block 22 together form a pouring mechanism, through which the molten metal enters the die-casting mold, and a die-casting cavity is formed between the male mold plate 3 and the female mold plate 2, and the pouring mechanism and the die-casting cavity are connected. Thus, the molten metal is injected from the pouring gate 11, enters the die-casting cavity through the guide column 14 and the diverter block 22, and solidifies in the die-casting cavity to form a multi-leaf transmission part, completing the production.

[0034] A accommodating cavity 23 is provided on one side of the mother template 2 close to the blade clamping unit 5, and a top mold 24 is placed in the accommodating cavity 23. The shape of the interior of the top mold 24 is the same as the shape of the top of the multi-leaf transmission part. The molten metal reaches the interior of the top mold 24 through the pouring mechanism, and after solidification, it forms the shape of the interior of the top mold 24, which is the top of the multi-leaf transmission part.

[0035] A placement cavity 31 is provided on one side of the male mold plate 3 close to the blade clamping unit 5, and a bottom mold 32 is placed in the placement cavity 31. The shape of the interior of the bottom mold 32 is the same as the shape of the bottom of the multi-leaf transmission part. The molten metal reaches the interior of the bottom mold 32 and forms the shape of the interior of the bottom mold 32 after solidification, which is the bottom of the multi-leaf transmission part.

[0036] The blade clamping unit 5 includes a core 51, a driving motor 52, an inclined guide column 53, a core pulling block 54, a limit block 55, an auxiliary block 56 and a cushion block 57. A plurality of inclined guide columns 53 are provided, and the inclined guide columns 53 are fixedly connected to the female mold plate 2 by bolts. The ends of the plurality of inclined guide columns 53 close to the female mold plate 2 are arranged in an annular manner about the center of the female mold plate 2, and the plurality of inclined guide columns 53 are arranged obliquely outward from the female mold plate 2 to the side of the male mold plate 3 along the center of the mold, and the inclination angles of the plurality of inclined guide columns 53 are all kept consistent. A plurality of auxiliary blocks 56 are fixedly connected to the side of the male mold plate 3 close to the blade clamping unit 5, and the auxiliary blocks 56 are arranged in an annular manner about the center of the male mold plate 3, and a sliding groove is formed between two adjacent auxiliary blocks 56, and the core pulling block 54 is located between two adjacent auxiliary blocks 56 and slides along the sliding groove.

[0037] The core pulling block 54 is set to a specific shape, and the inner ends of multiple core pulling blocks 54 abut against each other to form a central cavity. The interior of the core pulling block 54 is designed according to the required inclination angle of the blades, so that after the molten metal located inside the central cavity solidifies, blades with a specific inclination angle are formed along the shape of the interior of the core pulling block 54, and the exterior of the blades of the multi-leaf transmission component are formed by the inclination angle of the inner end of the core pulling block 54.

[0038] Reference Figure 7 and Figure 8 , the driving motor 52 is connected to the male mold plate 3, and a socket is provided in the center of the bottom mold 32, and the driving motor 52 is placed in the socket. The core 51 is connected to the output end of the driving motor 52, and the side wall of the core 51 is arranged in the socket. The top of the core 51 is inserted into the central cavity, and the top of the core 51 and the edge of the central cavity, that is, the inner end top of the core puller 54, are provided with a spacing, and the inner end bottom of the core puller 54 abuts against the bottom mold 32 and the top of the core 51. The top of the core 51 is set to a specific shape, so that when the molten metal flows into the central cavity, the molten metal will flow into the area between the top of the core 51 and the edge of the central cavity, and after solidification, the shape of the top of the core 51 forms the inside of the blade. The central cavity is connected with the inside of the top mold 24 and the inside of the bottom mold 32, and together constitutes a die casting cavity, so that the molten metal solidifies to form the top, bottom and middle blades of the multi-leaf transmission member, so that the multi-leaf transmission member can be formed in the die casting mold at one time.

[0039] The upper end of the core-pulling block 54 abuts against the top mold 24, so that the blades of the multi-leaf transmission member are connected to the top. The side wall of the core 51 is provided with an escape hole, so that the molten metal filled in the escape hole forms a connection between the blades and the bottom of the multi-leaf transmission member after solidification. The structural setting of the die-casting cavity makes the mold more compact, and at the same time ensures that when the movable mold and the top mold 24 are in close contact, the die-casting cavity forms a closed space, and the molten metal will not leak. A complete molten metal channel is formed by the pouring mechanism and the die-casting cavity, and the molten metal flows smoothly into the die-casting cavity, and the residual bubbles and pressure loss are reduced, which is beneficial to the improvement of product quality.

[0040] The driving motor 52 drives the core 51 to rotate, and the core 51 can drive the formed multi-leaf transmission member to rotate. The inclined guide column 53 is penetrated at the outer end of the core pulling block 54, so that the core pulling block 54 can slide along the direction of the inclined guide column 53. When the movable mold and the fixed mold are separated, the male mold plate 3 moves, driving the core pulling block 54 to slide along the direction of the inclined guide column 53, and the central cavity in the middle of the core pulling block 54 gradually expands; at the same time, the driving motor 52 drives the multi-leaf transmission member to rotate. In practice, a solidified metal rod may be formed on the upper side of the multi-leaf transmission member in the guide column 14, which will drive the top of the multi-leaf transmission member to separate from the metal rod in the guide column 14 during rotation, so that the top of the multi-leaf transmission member is separated, and the blades of the multi-leaf transmission member are simultaneously separated from the inner end of the core pulling block 54 during rotation, thereby realizing the demoulding of the blades of the multi-leaf transmission member.

[0041] A plurality of limit blocks 55 are fixedly connected to the male mold plate 3, and the limit blocks 55 are arranged on the outer side of the core pulling block 54, and the limit blocks 55 are arranged corresponding to the core pulling block 54. When the core pulling block 54 slides along the inclined guide column 53, the outer end of the core pulling block 54 gradually moves outward, and when the outer end of the core pulling block 54 abuts against the limit block 55, the core pulling block 54 cannot continue to move, so the limit block 55 limits the moving range of the core pulling block 54. The cushion block 57 is fixed to the side of the male mold plate 3 close to the core pulling block 54, and the core pulling block 54 and the cushion block 57 abut against each other, and the cushion block 57 also abuts against the side wall of the bottom mold 32. The setting of the cushion block 57 avoids direct contact between the core pulling block 54 and the male mold plate 3, reduces the friction between the core pulling block 54 and the male mold plate 3 and other components, reduces the wear of the core pulling block 54, ensures the stability and accuracy of the blade clamping unit 5 during die casting, and helps to improve the quality and yield rate of the final product.

[0042] Reference Figure 4 and Figure 5 An insertion port 33 is provided on the side of the male mold plate 3 close to the blade clamping unit 5, and the insertion port 33 is used to allow the inclined guide column 53 to be inserted. An insertion slot 25 is provided on the side of the female mold plate 2 close to the blade clamping unit 5, and the insertion slot 25 is used to allow the core pull block 54 and the limit block 55 to be inserted. When the male mold plate 3 and the female mold plate 2 are in close contact, the inclined guide column 53 is inserted into the insertion port 33, and the core pull block 54 and the limit block 55 are inserted into the insertion slot 25, so that the assembly accuracy of the mold is higher, ensuring the smooth operation of the blade clamping unit 5, and avoiding jamming or offset during the mold opening process.

[0043] Reference Figure 3 and Figure 4, the rear support plate 4 includes a lower ejector plate 41, an upper ejector plate 42, an ejector rod 43, a ball screw 45 and a lower mold foot 44. Two lower mold feet 44 are provided, and are respectively located at the two ends of the side of the male mold plate 3 away from the blade clamping unit 5. The lower ejector plate 41 and the upper ejector plate 42 are arranged between the two lower mold feet 44. The ball screw 45 is penetrated by the lower ejector plate 41, the upper ejector plate 42 and the male mold plate 3, and the ejector rod 43 is penetrated by the upper ejector plate 42 and the male mold plate 3. The rear support plate 4 is connected to a driving member for pushing the fixed mold and the movable mold to open and close. The driving member is used to drive the ball screw to push the movable mold close to or away from the fixed mold to realize the mold opening and closing process. When demolding, the driving member drives the lower ejector plate 41 and the upper ejector plate 42 to move, and the ejector rod 43 moves to eject the solidified multi-leaf transmission member from the male mold plate 3, thereby realizing the demolding process and facilitating the removal of the multi-leaf transmission member.

[0044] The implementation principle of a die-casting mold for the production of multi-leaf transmission parts for new energy vehicles in an embodiment of the present application is as follows: multiple core-pulling blocks 54 enter a preset position state, the male mold plate 3 and the female mold plate 2 are in close contact, the central cavity is connected with the interior of the top mold 24 and the interior of the bottom mold 32, and together constitute a die-casting cavity, the molten metal is injected from the gate 11, enters the die-casting cavity through the guide column 14 and the diverter block 22, the top of the multi-leaf transmission part is formed by the shape of the top mold 24, the bottom of the multi-leaf transmission part is formed by the shape of the bottom mold 32, the outer and inner sides of the middle blades are formed by the edge of the central cavity and the shape of the core 51, and the manufacturing and molding of the multi-leaf transmission part is completed.

[0045] During demolding, the driving member drives the male template 3 to separate from the female template 2 through the ball screw 45, driving the core pulling block 54 to slide along the direction of the inclined guide column 53, and the core pulling block 54 slides along the sliding groove formed by the auxiliary block 56. The central cavity in the middle of the core pulling block 54 gradually expands, and the driving motor 52 drives the multi-leaf transmission member to rotate through the core 51 to realize the demolding of the blades of the multi-leaf transmission member, and at the same time separates the top of the multi-leaf transmission member from the metal rod. The driving member drives the lower ejector plate 41 and the upper ejector plate 42 to move, and the ejector rod 43 moves to eject the solidified multi-leaf transmission member from the male template 3 to realize the demolding process.

[0046] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
