Description

Technical Field

[0001] The present invention relates to the technical field of casting molding dies, and particularly relates to a casting molding die for automotive parts. Background Art

[0002] A die-casting molding die is a tool or die used to manufacture die-cast products. Die-casting is a process in which molten metal is injected into a die and cooled and solidified under high pressure to form a shape. This molding method is commonly used to produce metal parts with complex shapes and precise dimensions, such as automotive parts, electronic components, industrial parts, etc.

[0003] After the molding die is opened, a release agent needs to be sprayed on the surface cavity of the die. When spraying the release agent, first, a pick-up robotic arm takes the automotive part out of the die, and then another robotic arm sprays. Two robotic arms need to work collaboratively in sequence. The bottleneck in the collaborative efficiency of the double robotic arms leads to an extended production cycle, and the operation is complex and prone to errors.

[0004] Timing conflict: The pick-up robotic arm needs to completely exit the die area before the spraying robotic arm can start operating, resulting in a process idle period of 6 - 8 seconds.

[0005] Risk of spatial interference: The overlapping area of the working radii of the double robotic arms reaches 35%, and a safety distance sensor needs to be configured.

[0006] When spraying the release agent on both dies during mold opening, in order to increase the spraying range, multiple nozzles are used to spray on both sides simultaneously. With the increase in the number of nozzles, the energy efficiency problem of the multi-nozzle system also arises. For each additional group of fan-shaped atomizing nozzles (discharge rate 60 ml / min), the following need to be increased: the air supply pressure requirement rises by 0.15 MPa, the power consumption of the hydraulic pump rises by 2.2 kW, and the liquid consumption rises by 8 - 1, which requires a certain power for the pump body. Summary of the Invention

[0007] The purpose of the present invention is to provide a casting molding die for automotive parts, which has the advantages of changing the nozzle direction of the spray rod for spraying the release agent on the cavity of the moving die core or the fixed die core. Using a single robotic arm can reduce the process idle period and does not require increasing the power of the pump. The airflow generated by the air pump can push the push frame to move the main rod, so as to change the nozzle direction of the spray rod and at the same time can clamp or loosen the automotive part. The two actions cooperate with each other, and using one air source saves costs.

[0008] To achieve the above purpose, the present invention provides the following technical solution: A casting molding die for automotive parts, comprising:

[0009] A die-casting mold, which is composed of a laterally opened mold base one and mold base two;

[0010] The mold core, which includes a movable mold core and a fixed mold core that are set in a matching manner, and are respectively assembled on the second mold base and the first mold base;

[0011] The second mold base slides along the guide rod passing through the first mold base, and is used to drive the movable mold core and the fixed mold core to switch between the open mold state and the closed mold state;

[0012] The carrier, which includes a first push block that slides horizontally and a second push block that slides vertically. The first push block and the second push block slide along the surface of the movable mold core for enclosing and defining;

[0013] The moving frame, on which a clamping part for clamping automotive parts, a swinging part and an adjusting part are assembled. The swinging part includes a rotating plate that rotates around the moving frame. A spray rod is assembled on the rotating plate. The rotating plate is hinged through a connecting rod part, and the connecting rod part is connected to a power device;

[0014] The adjusting part, which includes a push frame that reciprocates along the moving frame. The push frame pushes the telescopic connecting rod part to move to change the nozzle direction of the spray rod, and is used to spray the mold release agent into the mold cavity of the movable mold core or the fixed mold core.

[0015] Further, the first push block and the second push block are connected to their respective cylinders, and the carrier is driven by the cylinders to slide along the surface of the movable mold core. In the closed mold state, the carrier, together with the movable mold core and the fixed mold core, encloses and defines a die casting cavity. Among them, the pouring pipe assembled on the first mold base passes through the fixed mold core and is connected to the die casting cavity.

[0016] Further, the moving frame is installed on the robotic arm in the factory building, and the moving frame is driven by the robotic arm to move.

[0017] Further, the spray rod is provided with a row of nozzles. The bottom end of the spray rod is inserted into the assembly seat. The assembly seat is fixed on the moving frame through a bracket. The pipe connected to the side of the assembly seat is connected to a mold release agent tank with a pump.

[0018] Further, there are two sets of the swinging parts, which are symmetrically distributed on both sides of the moving frame. The shaft head connected to the center of the top of the rotating plate is inserted into the assembly seat. The shaft head and the spray rod are coaxially arranged and are connected through a rod body. The mold release agent pumped by the pump enters the spray rod through the assembly seat and is sprayed out from the nozzles.

[0019] Further, the connecting rod part is composed of a hinged connecting rod and a telescopic rod. Among them, the telescopic rod is composed of a main rod and a sub-rod. One end of the sub-rod is inserted into the main rod. The connection position of the other end of the sub-rod with the rotating plate is at an eccentric position. A locking component is arranged at the port of the sub-rod located inside the main rod;

[0020] The locking component includes a sleeve connected to the port of the sub-rod. One end of the sleeve is hinged with a first lock block and the other end is hinged with a second lock block. The sleeve is inserted by the guide tube of the main rod. The sleeve and the main rod are connected through a spring sleeved on the guide tube;

[0021] On both sides of the main rod, there are slot holes for the first locking block and the second locking block to be inserted.

[0022] Further, the power equipment includes a motor installed at the bottom of the moving frame. The shaft of the motor passes through the moving frame and is connected to a crankshaft. The main rod ports of the swing members on both sides are sleeved on the crankshaft. The rotation of the crankshaft is used to drive the swing members on both sides to swing simultaneously.

[0023] Further, on both sides of the pushing frame, there are pushing blocks inserted into the slot holes. During the reciprocating movement of the pushing frame, it contacts the first locking block or the second locking block, driving the first locking block or the second locking block to disengage from the slot hole, so as to push the secondary rod out of the main rod.

[0024] Further, a pneumatic component connected to the pushing frame and the clamping part is also arranged on the moving frame. The pneumatic component includes a cylinder body. The interior of the cylinder body is divided into a first chamber and a second chamber by a partition plate. The output pipe of the air pump is connected to the first chamber and the second chamber through a three-way pipe. The piston rod connected to the pushing frame is inserted into the first chamber, and the clamping part is connected to the second chamber through a pipeline.

[0025] Further, the annular cavity of the clamping part is connected to the second chamber. A number of telescopic rods arranged radially on the clamping part are connected to the annular cavity. The clamping plates connected to the ports of the telescopic rods clamp or release automotive parts under the action of the air pump.

[0026] The technical effects and advantages of the present invention:

[0027] 1. The pushing frame pushes the telescopic connecting rod member to move to change the nozzle direction of the spray rod, for spraying the release agent into the film cavity of the moving die insert or the fixed die insert. That is, the part picking and spraying can be combined together. Without increasing the power of the pump, the all-round spraying coverage can be achieved. Using a single robotic arm can reduce the process idle period, improve production efficiency. By precisely controlling the nozzle direction, it ensures that the release agent evenly covers the surface of the die insert, improves the demolding efficiency, reduces die damage, extends the service life, and optimizes the production process.

[0028] 2. The air flow generated by the air pump can not only push the main rod to move by the pushing frame to change the nozzle direction of the spray rod, but also clamp or release automotive parts. The two actions cooperate with each other, using one air source, saving costs. Description of the Drawings

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] To better understand a casting mold for automotive parts provided in this embodiment, first, a brief introduction to the existing casting molds is given below. After the mold is opened, a release agent needs to be sprayed on the surface cavity of the mold. When spraying the release agent, first, the automotive parts are removed from the mold by a picking robot arm, and then another robot arm sprays. Two robot arms need to work together successively, resulting in low production efficiency and complex operation. At the same time, when the mold is opened, the release agent is sprayed on both molds. To increase the spraying range, multiple nozzles are used to spray on both sides simultaneously. With the increase in the number of nozzles, the required air pressure intensity also increases, which requires a certain power of the pump body.

[0045] The specification aims to solve the above technical problems:

[0046] Embodiment 1: Refer to Figures 1-2 , which is the first embodiment of the present invention, provides a casting mold for automotive parts, including:

[0047] A die-casting mold 1, which is composed of a laterally opened mold base 11 and a mold base 12. The laterally opened mold base 11 and mold base 12 apply a more uniform force through lateral ejection than traditional ejector pins, which can reduce the rate of white top defects in thin-walled parts. The lateral opening of the mold can ensure that the mold maintains a stable posture in various complex working environments, especially on high-speed stamping production lines, which helps to produce products with accurate dimensions and regular shapes. The design of the lateral opening of the mold enables the mold to adapt to different production requirements and ensures stable operation in different production environments. In addition, the design of the lateral opening of the mold significantly reduces the time and workload required for mold maintenance and cleaning.

[0048] A mold core 2, which is a matching moving mold core and fixed mold core, and is respectively assembled on the mold base 12 and the mold base 11; the design of the mold core 2 ensures precise docking during the casting molding process and reduces the rejection rate caused by the misalignment of the mold core 2. The close cooperation between the moving mold core and the fixed mold core further improves the overall stability and service life of the mold. At the same time, the material selection and surface treatment process of the mold core 2 enable it to maintain excellent performance under high-temperature and high-pressure environments, ensuring the surface finish and dimensional accuracy of the casting.

[0049] The mold base 12 slides along the guide rod passing through the mold base 11, and is used to drive the moving mold core and the fixed mold core to switch between the open mold state and the closed mold state. The mold base 12 is pushed by an existing air cylinder or hydraulic cylinder to move, so as to realize the opening and closing actions of the moving mold core and the fixed mold core of the mold base 12;

[0050] Refer to Figures 2-3, the bearing member 3, the bearing member 3 includes a push block 1 31 sliding in the horizontal direction and a push block 2 32 sliding in the vertical direction, the push block 1 31 and the push block 2 32 slide along the surface of the movable mold core for enclosure and limitation, the push block 1 31 and the push block 2 32 are connected to their respective cylinders, the bearing member 3 is driven by the cylinder to slide along the surface of the movable mold core, and the bearing member 3 and the mold cavity of the movable mold core and the fixed mold core are enclosed to define the die-casting cavity in the mold closing state, wherein the pouring pipe assembled on the mold base 11 passes through the fixed mold core and is connected to the die-casting cavity;

[0051] The design of the pouring tube ensures smooth injection of molten metal, reduces pores and inclusions, and improves the quality of castings. The precise matching of push block 1 31 and push block 2 32 effectively controls the material flow during the casting molding process, ensures uniform cooling of all parts of the casting, and reduces deformation. The stability of the cylinder drive ensures the reliable operation of the carrier 3 in high-speed production, further improving production efficiency and casting consistency. The sliding trajectories of push block 1 31 and push block 2 32 have been optimized to reduce friction loss and extend the service life of the components. The special structural design of the pouring tube effectively avoids the backflow and eddy current of the molten metal, ensuring the density of the internal structure of the casting. In addition, the sealing device between mold base 1 11 and mold base 2 12 prevents the leakage of high-temperature molten metal, improving production safety and environmental protection. The intelligent control of the entire mold system realizes real-time monitoring and adjustment of the production process, further optimizing the production process.

[0052] Reference Figure 4 , a mobile frame 4, the mobile frame 4 is equipped with a clamping part 5 for clamping automobile parts, a swinging member 7 and an adjusting member 8, the swinging member 7 includes a rotating plate 71 rotating around the mobile frame 4, a spray rod 6 is installed on the rotating plate 71, the rotating plate 71 is hinged by a connecting rod 72, and the connecting rod 72 is connected to the power equipment; the design of the spray rod 6 enables it to flexibly adjust the spray angle under the drive of the rotating plate 71, to ensure that the molten metal evenly covers the mold cavity and improve the surface quality of the casting.

[0053] Reference Figures 5-6 There are two groups of swinging members 7, which are symmetrically distributed on both sides of the moving frame 4. The shaft head connected to the center of the top of the rotating plate 71 is inserted into the assembly seat 61. The shaft head and the spray rod 6 are coaxially arranged and the rod body is arranged between them. The release agent extracted by the pump enters the spray rod 6 through the assembly seat 61 and is sprayed from the nozzle.

[0054] The spray bar 6 is provided with a row of nozzles, the bottom end of the spray bar 6 is inserted into the assembly seat 61, the assembly seat 61 is fixed on the mobile frame 4 through a bracket, and the pipeline connected to the side of the assembly seat 61 is connected to the release agent tank with a pump. The nozzles are evenly distributed to ensure that the release agent covers the entire area, effectively reducing the risk of casting sticking.

[0055] Since the opening of the spray bar 6 is connected to the shaft head through the rod body, the opening of the spray bar 6 is communicated with the inner cavity of the assembly seat 61. At the same time, it is ensured that the spray bar 6 rotates synchronously with the shaft head and the rotating plate 71. The demoulding agent pumped by the pump is first sent into the assembly seat 61, and then flows into the spray bar 6 along the opening of the spray bar 6 and is ejected from the nozzle, so that the rotation of the spray bar 6 does not affect the transportation of the demoulding agent.

[0056] Refer to Figures 5-6 , Figures 8-9 , the power equipment includes a motor installed at the bottom of the moving frame 4. The shaft of the motor passes through the moving frame 4 and is connected to the crankshaft 9. The ports of the main rods 721 of the swing members 7 on both sides are sleeved on the crankshaft 9. The main rods 721 are inserted into the guide seats of the moving frame 4. The rotation of the crankshaft 9 is used to drive the swing members 7 on both sides to swing simultaneously.

[0057] The connecting rod member 72 is composed of a hinged connecting rod and a telescopic rod. Among them, the telescopic rod is composed of a main rod 721 and a sub-rod 722. One end of the sub-rod 722 is inserted into the main rod 721, and the connecting position of the other end of the sub-rod 722 and the rotating plate 71 is at an eccentric position.

[0058] By starting the motor to drive the rotation of the crankshaft 9, the crankshaft 9 pushes the connecting rod to reciprocate along the guide seat during the rotation process, and the connecting rod member 72 will be driven to swing during the reciprocating movement of the connecting rod, thereby pulling the spray bar 6 and the rotating plate 71 to swing continuously, so as to realize the dynamic adjustment of the spraying angle of the spray bar 6. And during the swinging process of the spray bar 6, the spraying range is increased to cover the moving die core or the fixed die core, improving the utilization rate of the molten metal and the overall quality of the casting. Ensure that the demoulding agent evenly covers the surface of the mold cavity, effectively improving the demoulding effect and surface finish of the casting, and further optimizing the production efficiency and the quality of the casting.

[0059] The adjusting member 8, the adjusting member 8 includes a push frame 81 that reciprocates along the moving frame 4. The push frame 81 pushes the telescopic connecting rod member 72 to move to change the nozzle direction of the spray bar 6 for spraying the demoulding agent on the film cavity of the moving die core or the fixed die core. The set push frame 81

[0060] The moving frame 4 is installed on the robotic arm in the factory building, and the moving frame 4 is driven by the robotic arm to move. The precise positioning and flexible control of the robotic arm ensure the efficient operation of the moving frame 4 in the complex space. The moving frame 4 is driven by the robotic arm to move to complete the precise control of the position of the moving frame 4.

[0061] The connecting rod member 72 is composed of a hinged connecting rod and a telescopic rod. Among them, the telescopic rod is composed of a main rod 721 and a sub-rod 722. One end of the sub-rod 722 is inserted into the main rod 721, and the connecting position of the other end of the sub-rod 722 and the rotating plate 71 is at an eccentric position. A locking component is arranged at the port of the sub-rod 722 located in the main rod 721;

[0062] The locking component includes a sleeve 726 connected to the port of the secondary rod 722. At both ends of the sleeve 726, a first locking block 724 and a second locking block 725 are hinged. The sleeve 726 is inserted by the guide tube 727 of the main rod 721. The sleeve 726 and the main rod 721 are connected by a spring sleeved on the guide tube 727.

[0063] Without external force, the sleeve 726 is pulled by the spring. The first locking block 724 and the second locking block 725 on both sides of the sleeve 726 will insert into the slot holes, realizing the locking state of the main rod 721 and the secondary rod 722. The opening force of the first locking block 724 and the second locking block 725 is provided by the spring, ensuring stable locking between the secondary rod 722 and the main rod 721 and preventing the secondary rod 722 from sliding along the main rod 721.

[0064] Slot holes for the first locking block 724 and the second locking block 725 to snap into are provided on both sides of the main rod 721. Push blocks inserted into the slot holes are provided on both sides of the push frame 81. During the reciprocating movement of the push frame 81, it contacts the first locking block 724 or the second locking block 725, driving the first locking block 724 or the second locking block 725 to disengage from the slot hole, for pushing the secondary rod 722 to extend from the main rod 721.

[0065] Working principle:

[0066] In the mold - closing state, the bearing part 3, the moving die insert and the cavity of the fixed die insert enclose and define a die - casting cavity. After the molten metal is injected into the die - casting cavity, the moving die insert and the fixed die insert are opened, and the first push block 31 and the second push block 32 slide along the moving die insert. The robotic arm drives the moving frame 4 to move between the moving die insert and the fixed die insert. The shaft head and the spray rod 6 are coaxially arranged and are connected by a rod body. The release agent pumped by the pump enters the spray rod 6 through the assembly seat 61 and is ejected from the nozzle. At the same time, the motor drives the crankshaft 9 to rotate. During the rotation of the crankshaft 9, it pushes the connecting rod to reciprocate along the guide seat, and during the reciprocating movement of the connecting rod, it drives the telescopic rod to swing, pulling the spray rod 6 and the rotating plate 71 to swing continuously, so as to realize the reciprocating swing of the spray rod 6. The spray rod 6 first sprays the release agent on the cavity of the fixed die insert by reciprocating swing.

[0067] The moving frame 4 moves to the clamping part 5 to clamp the automotive part casting and then takes out the casting from the moving die insert. At this time, the motor stops. Then the push frame 81 moves towards the main rod 721. The protruding push block of the push frame 81 will contact the first locking block 724 and push the first locking block 724 out of the slot hole. While the first locking block 724 retracts, it drives the sleeve 726 to slide along the guide tube 727. During the sliding of the sleeve 726, it also drives the second locking block 725 to disengage from another slot hole, and at this time the spring is compressed.

[0068] Spraying direction change:

[0069] As the pusher 81 continues to move, the pusher 81 pushes the main rod 721 to rotate around the connecting rod. At this time, the secondary rod 722 is not locked. During the process of pushing the main rod 721 to move, the secondary rod 722 slowly extends from the main rod 721, and the connected spring is slowly stretched. After the main rod 721 is pushed to rotate to a state straight with the connecting rod, when the pusher 81 continues to move, the pulling force of the spring rebound causes the secondary rod 722 to retract into the main rod 721. As the secondary rod 722 moves into the main rod 721, the first locking block 724 and the second locking block 725 are re-inserted into the slot holes to ensure the telescopic rod is locked. The motor continues to work. At this time, the connecting rod pulls the spray rod 6 to swing reciprocally and spray the mold release agent into the mold cavity of the stationary mold core, thereby realizing the spraying of the mold release agent on the stationary mold core and the moving mold core successively. By using the spray rod 6 to swing back and forth in sequence for spraying, the part picking and spraying can be combined together. At the same time, the all-round spraying coverage can be achieved without increasing the power of the pump, improving the production efficiency, reducing the energy consumption, ensuring the surface quality of the casting, optimizing the demolding effect, and reducing the maintenance cost.

[0070] Embodiment 2: Refer to Figures 10-12 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment. The power of the clamping part 5 of this structure comes from the pusher 81. When the spraying direction of the pusher 81 changes, it can drive the clamping part 5 to clamp or loosen.

[0071] An air-operated component connected to the pusher 81 and the clamping part 5 is further arranged on the moving frame 4. The air-operated component includes a cylinder block 10. The interior of the cylinder block 10 is divided into a first chamber and a second chamber by a partition. The output pipe of the air pump is connected to the first chamber and the second chamber through a three-way pipe. The piston rod connected to the pusher 81 is inserted into the first chamber, and the clamping part 5 is connected to the second chamber through a pipeline.

[0072] The annular cavity of the clamping part 5 is connected to the second chamber. A plurality of telescopic rods arranged radially on the clamping part 5 are connected to the annular cavity. The clamping plates 51 connected to the ports of the telescopic rods clamp or loosen the automotive parts under the action of the air pump.

[0073] After the spray bar 6 sprays the fixed mold core, the high-pressure air flow generated by the air pump enters the first chamber and the second chamber. The piston rod is pushed by the air flow to move and drives the push frame 81 to move towards the main rod 721. After the push frame 81 pushes the main rod 721 to move until the nozzle of the spray bar 6 faces the moving mold core, the piston rod moves to contact the inner wall of the cylinder block 10. At this time, all the air flow of the air pump flows into the annular cavity, causing the retractable rod to extend, and the clamping plate 51 clamps the automotive parts. The automotive parts are separated from the mold by the movement of the moving frame 4. Then, the negative pressure generated by the air pump extracts the gas in the first chamber and the second chamber. At this time, the push frame 81 moves in the reverse direction, pushing the main rod 721 to move in the reverse direction, making the nozzle of the spray bar 6 face the moving mold core, and the telescopic rod also shortens. At this time, the clamping plate 51 releases the automotive parts so as to take out the automotive parts. At the same time, it is also convenient for the next part picking. The diameter of the clamping plate 51 increases to fit outside the automotive parts. The two actions cooperate with each other, using one air source to save costs.

[0074] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
