Description

Technical Field

[0001] The present invention relates to the technical field of automotive molds, and more specifically, to a multi-station rotary mold for die-casting automotive shoe blocks. Background Art

[0002] Automotive shoe blocks are core components in drum brake systems, usually made of high-strength cast iron or alloy materials, in an arc-shaped sheet structure, and installed inside the brake drum. When the brake pedal is depressed, the shoe blocks expand outward under the push of the brake cylinder, and friction with the inner wall of the rotating brake drum generates braking force. Friction materials (brake linings) are often riveted or bonded to their surfaces to enhance the braking effect and reduce wear, and are widely used in the rear-wheel brake systems of commercial vehicles and mid- to low-end passenger cars.

[0003] Currently, automotive shoe blocks are mainly produced using gravity die casting or die-casting molds. The molds usually consist of an upper mold, a lower mold, side molds (sliders), and an ejection mechanism to adapt to the arc-shaped structure of the shoe blocks. Some high-efficiency production lines use multi-cavity molds (one mold with multiple parts) or rotary multi-station molds to improve production efficiency. Mold materials are generally selected as H13 hot work die steel to improve heat resistance and wear resistance.

[0004] Compared with existing automotive shoe block molds, current automotive shoe block molds still have obvious defects in the cooling system and demolding structure: in terms of cooling, the traditional linear cooling water channel layout is difficult to match the complex curved surface of the shoe block, resulting in uneven local heat dissipation, and the casting is prone to hot spots and shrinkage porosity problems; in terms of demolding, since existing automotive shoe blocks usually have complex geometric structures (such as arc-shaped curved surfaces, dense reinforcing ribs, and cross-sections with uneven thicknesses), and the ejector rod layout of traditional demolding mechanisms is usually limited to simple symmetric positions, the ejection force distribution is difficult to match the force requirements of the product, resulting in local stress concentration during demolding, and it is extremely easy to cause surface scratches, rib fractures, or overall warping of the casting. Summary of the Invention

[0005] The present invention provides a multi-station rotary mold for die-casting automotive shoe blocks. Through the coordinated improvement of the cooling system and the demolding mechanism, the mold can achieve uniform cooling and precise demolding, so as to ensure the quality of the casting while improving production efficiency, thereby solving the problems raised in the above background art, that is: The problem of uneven heat dissipation caused by traditional linear cooling water channels, and the problems of casting scratches and deformation caused by simple symmetric ejection mechanisms.

[0006] To achieve the above object, the multi-station rotary mold for die-casting automotive shoe blocks includes a rotating device, on the outer wall of which there are respectively a die-casting machine, a pouring machine, and a conveyor.

[0008] In another technical solution, the ejection component includes a support. The support is fixedly connected to the top of the turntable. A hydraulic cylinder is provided between the inside of the support and the turntable. The end of the hydraulic cylinder is fixedly connected with a top plate. The top plate is movably connected inside the support. A plurality of pushing members are fixedly connected to the top of the top plate.

[0009] The pushing member includes a top rod. The top rod is fixedly connected to the top of the top plate. A bolt is fixedly connected to the outer wall of the top rod. A cooling component is fixedly connected to the top of the support. The top rod is movably connected between the inside of the cooling component.

[0010] Among them, the ejection component drives the top plate and a plurality of asymmetrically distributed pushing members through a hydraulic cylinder to realize the profiling demolding function: the top rods of the pushing members are accurately arranged along the complex curved surface and rib positions of the hoof block body. During demolding, hydraulic pressure is applied synchronously to avoid local stress concentration, effectively preventing the casting from being scratched or deformed; at the same time, the movable connection design of the top rod inside the cooling component enables it to drive the flow member through the bolt during the ejection action, forcibly driving the coolant to circulate, dynamically coupling the demolding mechanical energy with the cooling system, and synchronously improving the demolding stability and cooling efficiency.

[0011] In this technical solution, the cooling component includes a mold frame. The mold frame is fixedly connected to the top of the support. A groove matching the hoof block body is provided at the top of the mold frame. A layered plate is fixedly connected inside the mold frame. Check valves are respectively provided near both ends inside the layered plate. A plurality of flow members are provided between the bottom of the layered plate and the inside of the mold frame.

[0012] A pushing member is provided inside the flow member. A plurality of the pushing members are movably clamped inside the groove of the mold frame, and the plurality of pushing members are distributed along the shape of the groove of the mold frame; the flow member includes a support rod. The support rod is movably connected to the outer wall of the bolt. A plurality of fan blades are fixedly connected to the outer wall of the support rod.

[0013] The one-way valve includes a valve housing, which serves as the main frame. Inside, there is a fluid passage and a mounting cavity. A piston is arranged inside the valve housing. One end of the piston is fixedly connected to a push rod, and the other end of the push rod is fixedly connected to a pressing plate.

[0015] The pushing component includes a bracket, which is fixedly connected between the outer walls of the conveyor. A cylinder is fixedly connected to the top of the bracket, and the end of the piston rod of the cylinder is fixedly connected to a pushing plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the coordinated linkage of multiple components, the overall improvement of the cooling and demoulding efficiency in the die-casting process of the automotive shoe block is realized; the turntable of the rotating device is driven by a motor, driving multiple mold bodies to cycle and switch to die-casting, cooling, demoulding and other stations, forming a continuous production flow; Among them, through the mechanical coupling design of the ejecting component and the cooling component, when the hydraulic cylinder drives the top plate, the ejector rod in the asymmetrically distributed pushing parts applies force precisely along the curved surface and reinforcing ribs of the shoe block body, avoiding stress concentration caused by traditional symmetric ejection. At the same time, the bolts on the outer wall of the ejector rod convert the demoulding mechanical energy into the coolant circulation power through the support rods and fan blades of the linkage flow parts, forcing the coolant to flow directionally in the three-dimensional water channels formed by the layered plates; Moreover, the one-way valve ensures the unidirectional and high-speed passage of the coolant through the thick-walled area through the coordinated control of the piston and the elastic member, eliminating the heat dissipation blind area caused by the traditional straight water channel; in addition, the cylinder and the pushing plate of the pushing component automatically push the casting into the conveyor after demoulding, realizing unmanned operation of the whole process.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] At present, in order to solve the problem of uneven heat dissipation caused by traditional linear cooling water channels and the problem of casting damage and deformation caused by simple symmetrical ejection mechanisms, the present invention provides a multi-station rotary mold for die casting of automobile shoe blocks, see Figures 1-11 As shown, it comprises a rotating device 1, the outer wall of the rotating device 1 is respectively provided with a die-casting machine 2, a pouring machine 3 and a conveyor 4, the outer wall of the conveyor 4 is provided with a pusher assembly 41, and the top of the rotating device 1 is provided with a plurality of mold bodies 5; The mold body 5 includes a cooling assembly 51 and an ejection assembly 52. ​​The plurality of ejection assemblies 52 are fixedly connected to the top of the rotating device 1. The top of the ejection assembly 52 is fixedly connected to the cooling assembly 51. The shoe body 6 is clamped inside the cooling assembly 51. The cooling component 51 is used to assist in the cooling of the shoe block body 6 during molding, and the ejection component 52 is used to demold the shoe block body 6 after die-casting molding and drive the coolant inside the cooling component 51 to circulate during the demolding process.

[0021] During implementation, refer to Figure 10 As shown, the rotating device 1 includes a plurality of struts 12. Rollers are provided at the tops of the struts 12. A turntable 13 is provided between the rollers of the plurality of struts 12. A motor 11 is fixedly connected to the center of the bottom of the turntable 13. A plurality of ejection components 52 are fixedly connected to the top of the turntable 13. When the rotating device 1 is working, the motor 11 is energized and operates, outputting power to drive the turntable 13 fixedly connected thereto to rotate. The turntable 13 rotates smoothly under the support of the rollers at the tops of the plurality of struts 12. The rollers effectively reduce the friction when the turntable 13 rotates, ensuring its smooth rotation. In this way, the plurality of ejection components 52 fixedly connected to the top of the turntable 13 rotate cyclically with the turntable 13, driving the mold body 5 to switch between different working stations such as die-casting, cooling, and demolding, forming a continuous production process and realizing efficient cyclic operation.

[0022] In addition, refer to Figure 1 、 Figure 9 and Figure 11 As shown, a die-casting machine 2, a pouring machine 3, and a conveyor 4 are respectively provided at the bottom of the turntable 13. A pusher assembly 41 is provided on the outer wall of the conveyor 4. The die-casting machine 2, the pouring machine 3, and the pusher assembly 41 are all located above the mold body 5. The pusher assembly 41 includes a bracket 410. The bracket 410 is fixedly connected between the outer walls of the conveyor 4. A cylinder 411 is fixedly connected to the top of the bracket 410. A push plate 412 is fixedly connected to the end of the piston rod of the cylinder 411. During operation, the turntable 13 rotates driven by the motor 11, driving the mold body 5 to cyclically switch working stations. When the mold body 5 rotates above the conveyor 4, the pusher assembly 41 is activated: after the cylinder 411 on the bracket 410 is energized, the piston rod extends, pushing the push plate 412 to push the formed shoe block body 6 from the mold body 5 onto the conveyor 4, completing demolding and conveying. At the same time, the die-casting machine 2 and the pouring machine 3 at the bottom of the turntable 13 respectively perform high-pressure die-casting and molten metal pouring operations on the mold body 5 at the corresponding working stations. Each device cooperates with each other, enabling the mold body 5 to sequentially complete processes such as pouring, die-casting molding, demolding, and conveying between different working stations, forming an automated continuous production.

[0023] Refer to Figure 5 As shown, the ejection component 52 includes a support 520. The support 520 is fixedly connected to the top of the turntable 13. A hydraulic cylinder 521 is provided between the inside of the support 520 and the turntable 13. The end of the hydraulic cylinder 521 is fixedly connected to a top plate 522. The top plate 522 is movably connected inside the support 520. A plurality of pushing members 523 are fixedly connected to the top of the top plate 522. The pushing member 523 includes a push rod 5230. The push rod 5230 is fixedly connected to the top of the top plate 522. A bolt 5231 is fixedly connected to the outer wall of the push rod 5230. A cooling component 51 is fixedly connected to the top of the support 520. The push rod 5230 is movably connected between the interiors of the cooling component 51. Among them, when the ejection assembly 52 works, the support 520 fixed to the top of the turntable 13 remains stable. After the internal hydraulic cylinder 521 is powered on, the piston rod extends, pushing the top plate 522 to move upward within the support 520. The movement of the top plate 522 drives the multiple pushing members 523 fixed to the top, that is, the push rods 5230. The push rods 5230 move within the cooling component 51. Due to the asymmetric distribution of the push rods 5230, force can be accurately applied along the complex curved surface and rib positions of the shoe body 6, avoiding local stress concentration and effectively preventing the casting from being scratched or deformed. At the same time, the bolts 5231 on the outer walls of the push rods 5230 link relevant components during the ejection action, providing power for the coolant circulation, dynamically coupling the demolding mechanical energy and the cooling system, and synchronously improving the demolding stability and cooling efficiency.

[0024] Figure 6 Among them, the cooling component 51 includes a die holder 510. The die holder 510 is fixedly connected to the top of the support 520. A groove matching the shoe body 6 is provided on the top of the die holder 510. A layered plate 511 is fixedly connected inside the die holder 510. Check valves 513 are respectively provided near both ends inside the layered plate 511. A plurality of flow members 512 are provided between the bottom of the layered plate 511 and the interior of the die holder 510.

[0025] In addition, referring to Figure 7 As shown, a pushing member 523 is provided inside the flow member 512. A plurality of pushing members 523 are movably clamped inside the groove of the die holder 510. The plurality of pushing members 523 are distributed along the shape of the groove of the die holder 510. The flow member 512 includes a support rod 5120. The support rod 5120 is movably connected to the outer wall of the bolt 5231. A plurality of fan blades 5121 are fixedly connected to the outer wall of the support rod 5120.

[0026] When the cooling component 51 works, the die holder 510 is fixed to the top of the support 520, and the groove on its top is adapted to the shoe body 6, providing space for molding; since the layered plate 511 is fixed inside the die holder 510, dividing a specific space, the check valves 513 at both ends of it control the one-way flow of the coolant, ensuring that the coolant passes through the thick-walled area of the shoe body 6 at high speed and eliminating the heat dissipation blind area; the flow members 512 provided between the bottom of the layered plate 511 and the interior of the die holder 510, and the pushing members 523 inside them are distributed along the shape of the groove of the die holder 510. When the ejector rod 5230 of the ejector assembly 52 moves, the bolt 5231 on the outer wall drives the support rod 5120 to rotate, and the fan blade 5121 on the outer wall of the support rod 5120 rotates accordingly, pushing the coolant to circulate inside the mold base 510; in this way, the coolant flows directionally in the three-dimensional water channels formed by the layered plate 511, solving the problem of uneven heat dissipation in the traditional straight water channels, and assisting the uniform cooling and forming of the shoe block body 6; at the same time, the pusher 523 is asymmetrically distributed, and can apply force precisely along the complex curved surface and rib positions of the shoe block body 6, avoiding local stress concentration during demolding and preventing the casting from being strained or deformed.

[0027] See Figure 8 As shown, the one-way valve 513 includes a valve housing 5130. The valve housing 5130 serves as the main frame, with a fluid passage and a mounting cavity inside. A piston 5134 is provided inside the valve housing 5130. One end of the piston 5134 is fixedly connected to a push rod 5132, and the other end of the push rod 5132 is fixedly connected to a pressing plate 5131. An elastic member 5133 is provided between the pressing plate 5131 and the fluid passage of the valve housing 5130; Through the coordinated action of the piston 5134, push rod 5132, pressing plate 5131 and elastic member 5133 inside the valve housing 5130, the one-way valve 513 realizes the one-way controllable flow of the coolant. One of the two one-way valves 513 is installed in the forward direction, and the other is installed in the reverse direction; among the two one-way valves 513, one installed in the forward direction is used to control the inflow path, and the other installed in the reverse direction is used to manage the return channel.

[0028] For the one-way valve 513 installed in the forward direction, in the initial state, the elastic member 5133 pushes the pressing plate 5131 to close the fluid passage inlet of the valve housing 5130, blocking the reverse flow path; when the ejector assembly 52 drives the fan blade 5121 of the flow member 512 to rotate, and the coolant flows in the designed direction, such as from the thin-walled area to the thick-walled area of the shoe block body 6, the fluid pressure acts on the pressing plate 5131, pushing the push rod 5132 to drive the piston 5134 to compress the elastic member 5133, opening the fluid passage, so that the coolant flows through the thick-walled area at high speed, specifically taking away high heat; if the coolant has a reverse flow tendency due to pressure fluctuations, the restoring force of the elastic member 5133 pushes the piston 5134 and the push rod 5132, making the pressing plate 5131 fit the channel inlet again, blocking the reverse flow; For the one-way valve 513 installed in the reverse direction, in the initial state, the pre-tightening force of the elastic member 5133 makes the pressing plate 5131 close the reverse fluid passage inlet, allowing the forward flow to be opposite to the flow direction of the forward valve; when the coolant needs to flow back along the other side of the layered plate 511 after dissipating heat in the thick-walled area, the fluid pressure of the reverse valve pushes the corresponding pressing plate 5131 to form a return channel, ensuring that the coolant circulates according to the designed path of the three-dimensional water channel; by preventing the coolant from flowing in the non-designed direction, the pressure stability of the circulation system is maintained; Therefore, by installing check valves 513 at both ends of the layered plate 511 in the forward and reverse directions respectively, a three-dimensional cooling circulation path of "directional inflow - efficient heat dissipation - controllable reflux" is formed: The forward valve ensures that the coolant preferentially flows through the thick-wall area (heat concentration area) of the shoe body 6 at high speed, eliminating local high temperature through enhanced heat dissipation; the reverse valve guides the coolant to flow back from the thick-wall area to the thin-wall area, avoiding the heat dissipation blind area caused by the single flow direction of the traditional straight waterway; the two-way check valve 513 cooperates with the mechanical drive of the flow member 512 to form a closed loop of the coolant inside the die carrier 510, avoiding flow stagnation or reflux loss caused by pressure fluctuations and improving the cooling efficiency; For the arc-shaped surface and uneven cross-section of the shoe body 6, the differential installation of the check valve 513 enables the coolant to flow directionally along the surface contour, achieving uniform heat dissipation by conforming to the complex structure of the casting, solving the problem of "overcooling at the proximal end and overheating at the distal end" of the traditional straight waterway, and reducing defects such as heat concentration and shrinkage porosity; Moreover, during the demolding process, the ejection assembly 52 drives the flow member 512 through the bolt 5231, synchronously activating the directional conduction function of the check valve 513, converting the demolding mechanical energy into cooling power, realizing the integrated linkage of "demolding - cooling", dynamically optimizing the cooling efficiency while improving the demolding stability, and ensuring the double improvement of the casting quality and production efficiency.

[0029] Working principle: First, the multi-station rotating device 1 drives the die body 5 to perform cyclic operations; when the motor 11 is powered on, it drives the turntable 13 to rotate smoothly under the roller support at the top of the column 12, driving multiple die bodies 5 fixed on the top of the turntable 13 to sequentially switch to stations such as pouring, die casting, cooling, and demolding; the roller design of the turntable 13 reduces friction and ensures stability during high-speed rotation; corresponding equipment for each station, the pouring machine 3, the die casting machine 2, and the conveyor 4 are arranged around the turntable 13 to form a continuous production line, realizing the multi-task parallel processing of the die body 5 and significantly improving the production efficiency; Subsequently, the molten metal pouring and die casting operations are carried out; when the die body 5 rotates to the pouring station, the pouring machine 3 injects the molten metal into the shoe groove at the top of the die carrier 510; subsequently, the die body 5 enters the die casting station, and the die casting machine 2 applies high pressure to the molten metal to completely fill the die cavity and compact it, initially forming the arc-shaped structure and internal ribs of the shoe body 6; this process depends on the precise design of the die groove to ensure that the casting dimensions and mechanical properties meet the requirements; Next, three-dimensional circulation cooling is achieved through the cooling component 51; when the mold body 5 enters the cooling station, the cooling component 51 is started to control the layered water path and the one-way valve 513; the cooling area is divided into two layers, upper and lower, by the layered plate 511 inside the mold frame 510, and the positive and negative one-way valves 513 are installed at both ends respectively; the positive valve allows the coolant to flow from the thin-walled area to the hot node concentration area of ​​the thick-walled area, and the negative valve controls the coolant to flow back from the thick-walled area to the thin-walled area, forming a three-dimensional circulation path of "directional inflow-controllable reflux"; Among them, the outer wall bolt 5231 of the ejector rod 5230 of the ejector assembly 52 is linked to the support rod 5120 and the fan blade 5121 of the flow member 512; when demoulding, the ejector rod 5230 moves, and the fan blade 5121 rotates to push the coolant to circulate in the cavity between the layered plate 511 and the mold frame 510, and flows through the thick wall area at high speed to take away the high heat, avoiding the heat dissipation blind area of ​​the traditional straight water channel, and solving the shrinkage and heat node problems caused by local overheating; Subsequently, the asymmetric ejector assembly 52 is precisely demoulded and coupled with cooling. When cooling is completed, the ejector assembly 52 is started to perform differentiated ejection force distribution. The hydraulic cylinder 521 drives the ejector plate 522 to drive the asymmetrically distributed ejector rods 5230 to be ejected synchronously along the complex curved surface and reinforcing ribs of the shoe body 6. The layout of the ejector rods 5230 fits the geometric features of the casting to ensure that the ejection force acts evenly on each stress point, avoiding local stress concentration caused by traditional symmetrical ejection, and preventing the casting from being strained, ribs broken, or overall warping and deformation. When the ejector 5230 moves, the bolt 5231 drives the flow member 512 to rotate, forcing the coolant circulation to be activated. This design converts the mechanical energy of the demoulding process into cooling power, so that the demoulding action and the coolant flow are performed synchronously, while improving the demoulding stability and dynamically optimizing the cooling efficiency, thus realizing the integrated coupling of "demolding-cooling". Finally, the automatic pushing and casting conveying operations are performed; when the mold body 5 rotates to the demolding station, the pushing assembly 41 on the outer wall of the conveyor 4 is started; the cylinder 411 drives the push plate 412 to push the formed shoe body 6 out of the groove of the mold frame 510, so that it falls onto the conveyor 4 and enters the subsequent cleaning, inspection or processing process; the pushing action is precisely coordinated with the rotation of the turntable 13 to ensure that the casting is quickly separated from the mold to avoid adhesion or damage, while making room for the pouring station of the next cycle.
