Description

Technical Field

[0001] This invention relates to the field of die-casting equipment technology, and in particular to a die-casting molding equipment for new energy vehicle parts. Background Technology

[0002] In the die-casting production of new energy vehicle parts, after continuous operation, metal debris, coolant, and release agent residues easily remain on the forming surface of the die-casting mold. Simultaneously, the mold temperature continues to rise, affecting the casting quality and mold lifespan. Therefore, after each mold opening and part removal, it is usually necessary to spray the forming surfaces of the moving and fixed mold components to clean, cool, and apply release agent. Traditional die-casting equipment generally uses an independent robotic arm carrying a spray nozzle assembly, which extends into the mold opening gap between the fixed and moving mold components after mold opening, and sprays the two forming surfaces separately through back-to-back spray nozzles.

[0003] Using an independent robotic arm to perform the spraying operation is not only complex in structure and has high equipment and maintenance costs, but also has poor coordination between the robotic arm's movements and the die-casting machine's mold opening and closing movements, occupies extra space outside the equipment, and has a lengthy overall operation process, which is not conducive to the efficient and continuous operation of the die-casting production line. Summary of the Invention

[0004] To address the above problems, the present invention provides the following technical solution: A die-casting molding equipment for new energy vehicle parts includes a die-casting machine body. The die-casting machine body has a fixed mold assembly and a moving mold assembly arranged opposite to each other. A rotating shaft is rotatably mounted on one side of the die-casting machine body near the fixed mold assembly, and a swing frame is fixedly mounted on the rotating shaft. A linkage mechanism is configured on the die-casting machine body. One end of the linkage mechanism is connected to the moving mold assembly, and the other end is driven to the swing frame. This linkage mechanism drives the swing frame to swing around the rotating shaft when the moving mold assembly performs an opening action relative to the fixed mold assembly, thereby swinging the end of the swing frame... The liquid is fed into the mold opening gap between the fixed mold assembly and the moving mold assembly; a drive base is mounted on the swing frame, and a liquid spraying pipe is provided in the drive base. The liquid spraying pipe is connected to an external liquid supply device. The liquid spraying pipe is provided with two spraying heads facing the forming surfaces of the fixed mold assembly and the moving mold assembly, respectively. The liquid spraying pipe has an openable structure. The liquid spraying pipe can be driven in the drive base to open, so that the two spraying heads approach the forming surfaces of the fixed mold assembly and the moving mold assembly, respectively, and perform spraying operations on the two forming surfaces.

[0005] Preferably, the linkage mechanism includes a rack, a gear, a mounting shaft, a bracket, a driving pulley, and a driven pulley. The rack is fixed to the moving mold assembly; the bracket is fixed to the die-casting machine body, and the mounting shaft is rotatably mounted on the bracket; both the gear and the driving pulley are fixedly mounted on the mounting shaft, and the rack can mesh or disengage with the gear; the driven pulley is fixedly mounted on the rotating shaft and connected to the driving pulley via a transmission belt. When the moving mold assembly moves relative to or in the opposite direction to the fixed mold assembly, it drives the rack to move synchronously, causing the rack to mesh or disengage with the gear. This, in turn, drives the rotating shaft to rotate via the mounting shaft, the driving pulley, the transmission belt, and the driven pulley, thereby causing the swing frame to move closer to or further away from the mold gap.

[0006] Preferably, the expandable structure of the spray pipe includes two symmetrically arranged spray branch pipes. One end of the two spray branch pipes is hinged to each other and folded into the drive base. The other end is respectively fixed with a spray head. The hinge point of the two spray pipes is connected to the liquid supply end of the spray pipe.

[0007] Preferably, the drive base is provided with an elastic drive element for driving the openable structure of the spray pipe to achieve the opening action, and for providing an elastic force to make the two spray branches swing away from each other.

[0008] Preferably, the spray head is provided with a plurality of spray holes, which are evenly distributed in a matrix, and the axis of the spray holes is set at an angle of 45°-60° with the forming surface of the corresponding fixed mold assembly and the moving mold assembly.

[0009] Preferably, a solenoid valve is provided at the connection between the spray pipe and the external liquid supply device. The solenoid valve is used to control the on / off connection between the spray pipe and the external liquid supply device, and the solenoid valve is linked to the mold opening signal of the die casting machine.

[0010] Preferably, the end of the swing frame is connected to a bend plate, the bend plate forms an angle with the swing frame, and the drive base is fixed to the bend plate.

[0011] Preferably, the drive base is sleeve-shaped, and the two spray branch pipes are folded in a V-shape within the cavity of the drive base with the hinge end as the inflection point. The ends of the two spray branch pipes where the spray heads are installed extend outside the cavity of the drive base. A carrier plate is fixed to the end of the drive base away from the spray heads, and a servo motor is fixed to the carrier plate. The actuation shaft of the servo motor passes through the carrier plate and enters the cavity of the drive base, where an adjusting screw is connected. A traction plate is slidably fitted within the cavity of the drive base. The hinged ends of the spray branch pipes are rotatably connected to the traction plate. There are two elastic drive members, which are bent spring structures. The two elastic drive members are spirally wound around the spray branch pipe along the length direction. One end of the drive member is wound to the free end of the spray branch pipe, and the other end is wound to the hinged end of the spray branch pipe and connected to the traction plate. The traction plate has a threaded hole, which is screwed onto the adjusting screw. The traction plate also has a pipe connection hole for connecting to the liquid supply end pipe of the two spray branch pipes.

[0012] The advantages of this invention compared to the prior art are: This invention solves the technical problems of complex structure and lengthy operation caused by using an independent robot to perform spraying operations in traditional die casting equipment. It realizes the synchronous linkage between the spraying component and the die casting machine's mold opening and closing actions, eliminating the need for an additional independent robot and drive control mechanism, thus simplifying the equipment structure and reducing costs. One end of the linkage mechanism is connected to the moving mold assembly, and the other end is driven to cooperate with the swing frame. When the moving mold assembly opens relative to the fixed mold assembly, it can drive the swing frame to swing around the rotating shaft, sending the end of the swing frame into the mold opening gap between the fixed mold assembly and the moving mold assembly. At the same time, the drive base and the openable spray pipe mounted on the swing frame drive the spray pipe to open within the drive base, driving two spray heads facing the forming surfaces of the fixed mold assembly and the moving mold assembly respectively to approach the corresponding forming surfaces and perform spraying operations.

[0015] The above and other embodiments and advantages 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.

[0016] In one implementation, such as Figures 1-6 As shown: A die-casting molding equipment for new energy vehicle parts includes a die-casting machine body 1. The die-casting machine body 1 has a fixed mold assembly 2 and a moving mold assembly 3 arranged opposite to each other. A rotating shaft 4 is rotatably mounted on one side of the fixed mold assembly 2 on the die-casting machine body 1. A swing frame 5 is fixedly mounted on the rotating shaft 4. A linkage mechanism 6 is configured on the die-casting machine body 1. One end of the linkage mechanism 6 is connected to the moving mold assembly 3, and the other end is driven to cooperate with the swing frame 5. When the moving mold assembly 3 performs an opening action relative to the fixed mold assembly 2, the linkage mechanism 6 drives the swing frame 5 to swing around the rotating shaft 4, thus sending the end of the swing frame 5 to... The mold opening gap 8 is between the fixed mold assembly 2 and the moving mold assembly 3; the swing frame 5 is equipped with a drive base 9, and the drive base 9 is provided with a spray pipe 10. The spray pipe 10 is connected to an external liquid supply device. The spray pipe 10 is provided with two spray heads 12 facing the forming surface of the fixed mold assembly 2 and the forming surface of the moving mold assembly 3 respectively; the spray pipe 10 is an openable structure. The spray pipe 10 can be driven to open within the drive base 9, so that the two spray heads 12 approach the forming surface of the fixed mold assembly 2 and the forming surface of the moving mold assembly 3 respectively, and perform spraying operations on the two forming surfaces.

[0017] When the equipment is working, the fixed mold assembly 2 and the moving mold assembly 3 on the die casting machine body 1 first complete the mold closing action to carry out the die casting molding operation of new energy vehicle parts. After the die casting is completed, the moving mold assembly 3 moves relative to the fixed mold assembly 2 to open the mold. At this time, an opening gap will be formed between the fixed mold assembly 2 and the moving mold assembly 3, allowing the operator to take out the die-cast workpiece.

[0018] During the mold opening motion of the moving mold assembly 3, since one end of the linkage mechanism 6 is connected to the moving mold assembly 3 and the other end is driven by the swing frame 5, the linear motion of the moving mold assembly 3 is converted into the rotational motion of the swing frame 5 through the linkage mechanism 6. This drives the swing frame 5 to swing around the rotating shaft 4 on the die-casting machine body 1, thereby sending the end of the swing frame 5 into the aforementioned mold opening gap. Because the drive base 9 is mounted on the end of the swing frame 5 and the spray pipe 10 is located inside the drive base 9, when the swing frame 5 swings, it will simultaneously drive the drive base 9 and the spray pipe 10 into the mold opening gap, realizing the position transfer of the spray pipe 10 and the spray head 12. The feeding action of the spraying component into the mold opening gap can be completed without the need for an additional robotic arm.

[0019] When the spray pipe 10 enters the mold opening gap with the swing frame 5, the spray pipe 10 is driven to open within the drive base 9. Since the spray pipe 10 is an openable structure, its opening action can drive the two spray heads 12 to approach the forming surface of the fixed mold assembly 2 and the forming surface of the moving mold assembly 3 respectively, until the two spray heads 12 are aligned with the working area of ​​the corresponding mold surface. At this time, the external liquid supply device connected to the spray pipe 10 supplies the spraying medium into the spray pipe 10. The medium is transported to the two spray heads 12 through the spray pipe 10, and the spraying operation is performed synchronously on the forming surfaces of the fixed mold assembly 2 and the moving mold assembly 3 through the spray heads 12, completing auxiliary processes such as cleaning, cooling and spraying of mold release agent on the mold surface. After the spraying operation is completed, the moving mold assembly 3 closes relative to the fixed mold assembly 2. The linkage mechanism 6 drives the swing frame 5 to swing around the rotating shaft 4 in the opposite direction, causing the drive base 9, spray pipe 10 and spray head 12 to disengage from the mold gap and return to the initial position, preparing for the next die casting and spraying operation.

[0020] The die-casting molding equipment for new energy vehicle parts provided in this embodiment has significant technical advantages compared to existing technologies: The linkage mechanism 6 links the opening and closing motion of the moving mold assembly 3 with the swing motion of the swing frame 5, achieving automatic feeding and resetting of the spray pipe 10 and spray head 12. This completely eliminates the need for a separate robotic arm used to carry the spray components in traditional equipment, effectively simplifying the equipment structure and reducing manufacturing and maintenance costs. The spray pipe 10 adopts an openable structure, enabling it to drive the two spray heads 12 to approach the forming surfaces of the fixed mold assembly 2 and the moving mold assembly 3 respectively after entering the mold opening gap. This ensures the accuracy and comprehensiveness of the spraying operation, improves the cleaning, cooling, and release agent spraying effects on the mold surface, thereby guaranteeing the forming quality of subsequent die-cast parts and extending the mold's service life. The movement of the spray components is synchronized with the opening and closing motion of the die-casting machine, eliminating the need for an additional independent drive control mechanism. This simplifies the workflow, improves the continuous operating efficiency of the die-casting production line, and meets the large-scale, high-efficiency production needs of new energy vehicle parts.

[0021] In another embodiment, the linkage mechanism 6 includes a rack 16, a gear 17, a mounting shaft 18, a bracket 19, a driving pulley 20, and a driven pulley 21. The rack 16 is fixed to the moving mold assembly 3; the bracket 19 is fixed to the die-casting machine body 1, and the mounting shaft 18 is rotatably mounted on the bracket 19; both the gear 17 and the driving pulley 20 are fixedly mounted on the mounting shaft 18, and the rack 16 can mesh with or disengage from the gear 17; the driven pulley 21 is fixedly mounted on the rotating shaft 4 and is connected to the driving pulley 20 via a transmission belt. When the moving mold assembly 3 moves relative to or in the opposite direction to the fixed mold assembly 2, it drives the rack 16 to move synchronously, causing the rack 16 to mesh with or disengage from the gear 17. This, in turn, drives the rotating shaft 4 to rotate via the mounting shaft 18, the driving pulley 20, the transmission belt, and the driven pulley 21, thereby driving the swing frame 5 to move closer to or further away from the mold gap.

[0022] During equipment operation, when the moving mold assembly 3 performs a linear motion relative to the fixed mold assembly 2 for mold opening or closing, it will drive the rack 16 to move synchronously. After the rack 16 follows the moving mold assembly 3 for a short period of idle travel (the demolding time of the product during mold opening), it enters the meshing zone with the gear 17. Only then does the linear motion of the rack 16 begin to drive the gear 17 and the mounting shaft 18 to rotate. Before the meshing drive, the molded product is demolded. When the linkage drive is carried out in the meshing zone, the torque is transmitted to the rotating shaft 4 through the driving pulley 20, the transmission belt, and the driven pulley 21, causing the rotating shaft 4 to drive the swing frame 5 to swing around the axis, thereby realizing the action of sending the spraying assembly into the mold opening gap or out of the gap. After the rack 16 disengages from the gear 17, the swing frame 5 can maintain its current position and no longer move with the moving mold, thus realizing the segmented coordination of the swing action and the mold opening and closing action time period.

[0023] The aforementioned linkage structure combining rack 16, gear 17, and pulley allows direct use of the moving mold's own opening and closing power to drive the swing frame 5, eliminating the need for an additional drive motor and control system. This results in a simple structure, reliable transmission, and highly synchronized action response with the die-casting machine's opening and closing stroke. Furthermore, the disengageable design of the rack and gear allows for flexible control of the swing frame's start and stop timing, preventing interference during mold closing, improving overall operational stability and safety, and facilitating subsequent assembly, debugging, and maintenance.

[0024] In another embodiment, the expandable structure of the spray pipe 10 includes two symmetrically arranged spray branch pipes 22. One end of the two spray branch pipes 22 is hinged to each other and folded into the drive base 9. The other end is fixed with a spray head 12. The hinge point of the two spray pipes 10 is connected to the liquid supply end of the spray pipe 10.

[0025] In another embodiment, the drive base 9 is provided with an elastic drive member 23 for driving the openable structure of the spray pipe 10 to realize the opening action. The elastic drive member 23 is a bending spring, the bending part of which is located at the hinge of the two spray branch pipes 22, and its two free ends are respectively sleeved on the two spray branch pipes 22 to provide an elastic force that causes the two spray branch pipes 22 to swing away from each other.

[0026] Before the spray pipe 10 enters the mold opening gap with the swing frame 5, the two spray branch pipes 22 remain folded under the limiting action of the drive base 9. At this time, the spring-shaped elastic drive element 23 is in a compressed and energy-storing state. After the spray pipe 10 enters the mold opening gap, the limiting action of the drive base 9 on the spray branch pipes 22 is released, and the elastic drive element 23 releases its elastic potential energy. Its two free ends apply elasticity in opposite directions to the two spray branch pipes 22, driving the two spray branch pipes 22 to swing synchronously away from the hinge, thereby driving the two spray heads 12 to approach the forming surface of the fixed mold assembly 2 and the forming surface of the moving mold assembly 3, respectively, until the preset spraying position is reached. After the spraying operation is completed, the spray pipe 10 leaves the mold opening gap with the swing frame 5. Under the limiting action of the drive base 9, the two spray branch pipes 22 are squeezed back to the folded state, and the spring is compressed and energy-storing again, preparing for the next opening action.

[0027] The above-mentioned openable spray pipe structure and spring drive structure have significant technical advantages: the two spray pipes 22 adopt a hinged folding design, which is simple and compact, effectively reducing the space occupied by the spray pipes in the non-working state, avoiding motion interference with other parts of the equipment, and facilitating assembly inside the drive base 9; the spring, as the elastic drive component 23, has a simple structure, low cost, and long service life, and can realize the automatic opening and resetting of the spray pipes 22 without the need for additional drive components such as motors and cylinders, further simplifying the equipment; the elastic force provided by the elastic drive component 23 is stable and continuous, which can ensure that the two spray pipes 22 swing smoothly and synchronously away from each other, so that the spray head 12 can accurately approach the corresponding mold surface, ensuring the uniformity and comprehensiveness of the spraying operation.

[0028] In another embodiment, the spray head 12 is provided with a plurality of spray holes, which are evenly distributed in a matrix, and the axis of the spray holes is set at an angle of 45°-60° with the forming surfaces of the corresponding fixed mold assembly 2 and moving mold assembly 3.

[0029] Several spray nozzles are evenly arranged in a matrix pattern on the end face of the spray head 12 facing the mold surface. The spacing between adjacent spray nozzles is consistent, ensuring that the sprayed medium can evenly cover the entire forming surface of the fixed mold assembly 2 and the moving mold assembly 3, avoiding spray blind spots. At the same time, the axis of the spray nozzle is set at an angle of 45°-60° with the corresponding mold surface, rather than perpendicularly facing the mold surface. This avoids the splashing and waste of the medium caused by the sprayed medium directly impacting the mold surface perpendicularly, and allows the sprayed medium to flow along the tangential direction of the mold surface, enhancing the cleaning effect of the mold surface. It also increases the contact area and contact time between the cooling medium and the mold surface, optimizing the cooling efficiency, and allows the release agent to adhere evenly to the mold surface, avoiding localized accumulation or leakage of the release agent. It should be noted that the spray head 12 deflects upward with the swing frame 5, and immediately performs a spraying action on one side, so that the spray nozzle is aligned with the mold forming surface and sprays evenly from bottom to top, improving the cleaning quality.

[0030] This type of spray head with 12 structures uses a matrix-style uniform distribution of a large number of spray holes, which can achieve comprehensive and uniform spraying on the forming surface, completely eliminating spray blind spots and ensuring consistent cleaning, cooling and release agent spraying effects in all areas of the mold surface, thereby ensuring the stability of the casting quality. The 45°-60° angle setting takes into account both spraying pressure and spraying effect, avoiding the media waste and splashing problems of vertical spraying, improving media utilization and operation effect, and reducing the consumption cost of spraying media.

[0031] In another embodiment, a solenoid valve is provided at the connection between the spray pipe 10 and the external liquid supply device. The solenoid valve is used to control the opening and closing of the spray pipe 10 and the external liquid supply device, and the solenoid valve is linked with the mold opening signal of the die casting machine.

[0032] The solenoid valve is installed in series in the connecting pipeline between the spray pipe 10 and the external liquid supply device. Its core function is to realize the on-off control of the spray pipe and ensure that the spraying operation is only performed under the preset working conditions. Since the solenoid valve is linked to the mold opening signal of the die casting machine, when the die casting machine completes the mold opening action, the swing frame 5 drives the spray pipe 10 into the mold opening gap and the spray pipe 10 completes the opening action, the mold opening signal sent by the die casting machine will trigger the solenoid valve to act, so that the solenoid valve is turned on, and the spraying medium of the external liquid supply device is delivered to the spray head 12 through the spray pipe 10 to perform the spraying operation. When the spraying operation is completed and the die casting machine sends the mold closing signal, the solenoid valve closes synchronously to cut off the liquid supply pipeline, avoid waste of spraying medium, and at the same time prevent medium leakage during the mold closing process from contaminating the equipment or affecting the mold closing accuracy.

[0033] In another embodiment, the end of the swing frame 5 is connected to a crank plate 7, which forms an angle with the swing frame 5, and the drive base 9 is fixed on the crank plate 7.

[0034] The bend plate 7 adopts a rigid plate structure, and one end of it is fixedly connected to the end of the swing frame 5. The connection method can be welding or bolt fastening to ensure the connection strength and meet the installation and bearing requirements of the drive base 9 and the spraying assembly. A fixed angle is formed between the bend plate 7 and the swing frame 5. This angle can be preset according to the size of the mold opening gap and the forming surface position of the fixed mold assembly 2 and the moving mold assembly 3. This ensures that when the swing frame 5 swings around the rotation axis 4 and enters the mold opening gap, the drive base 9 fixed on the bend plate 7 can drive the spraying pipe 10 and the spraying head 12 to accurately align with the two forming surfaces without the need for additional adjustment of the installation angle of the spraying assembly.

[0035] In another embodiment, the drive base 9 is sleeve-shaped, with two spray branch pipes 22 folded in a V-shape at the hinged ends within the cavity of the drive base 9. One end of each spray branch pipe 22, equipped with a spray head 12, extends outside the cavity of the drive base 9. A carrier plate 24 is fixed to the end of the drive base 9 away from the spray head 12. A servo motor 25 is fixed on the carrier plate 24. The actuation shaft of the servo motor 25 passes through the carrier plate 24 and enters the cavity of the drive base 9, connected to an adjusting screw 28. A traction plate 26 is slidably fitted within the cavity of the drive base 9. The hinged ends of the two spray branch pipes 22 are rotatably connected. On the traction plate 26, there are two elastic drive members 23, which are bent spring structures. The two elastic drive members 23 are spirally wound around the two spray branch pipes 22 along the length direction. One end of the drive member is wound to the free end of the spray branch pipe 22, and the other end is wound to the hinge end of the spray branch pipe 22 and connected to the traction plate 26. This is used to provide elastic potential energy to the spray branch pipe 22 to deflect towards the mold forming surface. The traction plate 26 has a threaded hole 27, which is screwed onto the adjusting screw 28. The traction plate 26 also has a pipe connection hole 29 for connecting to the liquid supply end of the two spray branch pipes 22.

[0036] The sleeve-shaped drive base 9 provides a stable installation and movement space for the spray branch pipes 22, the traction plate 26, and the adjusting screw 28, ensuring that the actions of each component do not interfere with each other. The two spray branch pipes 22 are folded in a V-shape at the hinge end and housed in the cavity of the drive base 9, which saves installation space and protects the spray branch pipes 22 from collision damage when not in operation. At the same time, the end where the spray head 12 is installed extends out of the cavity, ensuring that the spray head 12 can perform spraying operations normally. The carrier plate 24 is fixed to the end of the drive base 9 away from the spray head 12 and is used to support the servo motor 25, ensuring that the servo motor 25 is installed firmly and that its actuation shaft can stably transmit power.

[0037] When the spray pipe 10 enters the mold opening gap along with the swing frame 5, the servo motor 25 starts, and its actuation shaft drives the adjusting screw 28 to rotate synchronously. Since the adjusting screw 28 is screwed into the threaded hole 27 on the traction plate 26, and the traction plate 26 is slidably engaged with the cavity of the drive base 9, the rotation of the adjusting screw 28 is converted into linear motion of the traction plate 26 along the axial direction of the cavity of the drive base 9. When the traction plate 26 moves, it drives the hinged ends of the two spray branch pipes 22 to move synchronously, thereby causing the spray branch pipes 22 to rise and fall along the cavity of the drive base 9. When moving upward, the elastic drive member 23 coiled on the spray branch pipe 22 gradually releases potential energy because the capacity in the cavity of the drive base 9 decreases. Furthermore, since the elastic drive member 23 itself is a flexible element that bends towards the molding surface, it also releases potential energy. The spring structure allows the spraying branch pipes 22 to rise, thus increasing the deflection potential energy of the elastic drive component 23 towards the mold forming surface. Simultaneously, the two spraying branch pipes 22, with the hinge end as the inflection point, swing open from their V-shaped folded state to opposite sides, driving the spray head 12 closer to the corresponding mold surface. Even if the moving and stationary mold forming surfaces are far apart, this secondary driving method allows the spraying branch pipes 22 to approach the forming surface until the preset spraying position is reached. After the spraying operation is completed, the servo motor 25 rotates in the opposite direction according to the set threshold, driving the adjusting screw 28 to rotate in the opposite direction. The traction plate 26 moves in the opposite direction, pulling the two spraying branch pipes 22 back to their V-shaped folded state, essentially retracting into the cavity of the drive base 9. The pipe connection hole 29 on the traction plate 26 connects the external liquid supply device to the liquid supply end of the two spraying branch pipes 22, ensuring that the spraying medium can be smoothly delivered to the spraying branch pipes 22 and the spray head 12, guaranteeing smooth spraying operation.
