Description

Technical Field

[0001] This invention relates to the field of aluminum-magnesium alloy processing equipment, specifically a forming fixture for hot forming of die-cast aluminum-magnesium alloys. Background Technology

[0002] Aluminum-magnesium alloys typically refer to aluminum alloys with magnesium as the main additive element. They have advantages such as high strength, low density, and good heat dissipation, and are widely used in electronics, automobiles, aerospace and other fields. They also have many advantages such as high specific strength, low density, corrosion resistance, recyclability, good thermal conductivity, electromagnetic radiation protection, and thin-wall forming.

[0003] Aluminum-magnesium alloys possess a certain load-bearing capacity and good heat dissipation performance, making them suitable for products with high heat dissipation requirements. Their thermal conductivity is 100 times that of PP material, they have a low modulus of elasticity, good rigidity, and are not easily deformed during long-term use. They also have strong shock resistance, good resistance to electromagnetic interference and electromagnetic shielding, bright and beautiful colors, corrosion resistance, and can maintain their appearance quality for a long time. Furthermore, they are environmentally friendly materials, and their waste can be recycled.

[0004] When die-casting and hot-forming aluminum-magnesium alloys, the initial workpiece can be processed into the required shape by clamping the side molds on both sides, in conjunction with the upper and lower molds. However, traditional equipment cannot demold in a timely and convenient manner after die-casting and hot-forming. The workpiece is easily stuck in the lower mold after die-casting, which will cause inconvenience for the staff to remove it.

[0016] Compared with the prior art, the present invention provides a forming fixture for hot forming of die-cast aluminum-magnesium alloys, which has the following beneficial effects: 1. This forming fixture for hot forming of die-cast aluminum-magnesium alloys is equipped with an ejector assembly to better and more promptly demold the workpiece. When the two side molds move away from each other, the assembly works with a long groove, a moving block, a side rack, a bottom block, a rotating shaft, a side gear, a central gear, an L-shaped frame, a central rack, and a square groove to allow the slider to slide upward inside the slide rail, thereby lifting the workpiece and enabling better and more timely demolding.

[0017] 2. This forming fixture for hot forming of die-cast aluminum-magnesium alloys is equipped with an adsorption component to make the ejection of the workpiece more stable. When the slider moves upward, it works with the piston rod, air cylinder, three-way branch pipe, clamping block and telescopic air pipe to draw the airflow at the top of the telescopic air pipe downward, thereby creating a suction force on the bottom of the workpiece, which makes the workpiece more stable during the lifting process.

[0018] 3. This forming fixture for hot forming of die-cast aluminum-magnesium alloys incorporates a stabilizing mechanism to ensure greater stability during workpiece ejection. When the slider moves upward, it works in conjunction with a U-shaped block, torsion spring, and limiting plate to rotate the bottom of the sliding rod outside the rotating rod, causing the roller to roll at the bottom of the workpiece. This effectively prevents tipping during ejection, thus making the entire process more stable. 4. To facilitate smoother demolding, this forming fixture for hot forming of die-cast aluminum-magnesium alloys includes auxiliary components. When the slider moves upward, the L-shaped block separates from the arc-shaped block. This, combined with the short groove, square block, and clamping spring, causes the round rod to slide towards the sliding rod. This, along with the fixing block and spring rod, causes the inclined block to move upward, striking the workpiece and allowing it to leave the mold more easily, thus facilitating subsequent demolding.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0021] Please see Figure 1-10 This invention provides a technical solution: a forming fixture for hot forming of die-cast aluminum-magnesium alloys, comprising a frame 1, support legs fixedly installed at the four corners of the bottom of the frame 1, a bracket 2 fixedly installed at the top of the frame 1, a control console 3 fixedly installed on the outer wall of the front end of the frame 1, servo hydraulic cylinders 4 fixedly installed on the outer walls of the frame 1 in the left and right directions, the servo hydraulic cylinders 4 being electrically connected to the control console 3, a side mold 5 fixedly installed on the piston end of the servo hydraulic cylinder 4 facing the center of the frame 1, a servo hydraulic press 6 fixedly installed at the top center of the bracket 2, the servo hydraulic press 6 being electrically connected to the control console 3, and an upper mold 7 fixedly installed on the piston end of the bottom of the servo hydraulic press 6. A servo heater 8 is fixedly installed on the top of the bracket 2. The servo heater 8 is electrically connected to the control console 3. The servo heater 8 is electrically connected to the upper mold 7 through a wire. A lower mold 9 is fixedly installed at the center of the top of the frame 1. First, the servo hydraulic cylinder 4 is started through the control console 3, so that the two side molds 5 are brought closer together until they are pressed together. Then, the servo hydraulic press 6 is started to drive the upper mold 7 to move downward. Then, the servo heater 8 is started, so that the die casting and hot forming of the workpiece can be completed. After the operation is completed, the reverse operation is performed so that the control console 3 moves the two side molds 5 away from each other. The bottom end of the servo hydraulic press 6 is provided with an ejection assembly 10, an adsorption assembly 11 and a stabilizing mechanism 12.

[0022] Please see Figure 3-10 In one embodiment of the present invention, the ejection assembly 10 includes a long groove 101. The top of the frame 1 has a through long groove 101. The bottom of the side mold 5 is fixedly connected to the top of the moving block 102. The outer wall of the moving block 102 slides against the inside of the long groove 101. Further, when the two side molds 5 move away from each other, the two sets of moving blocks 102 move away from each other inside the long groove 101. The bottom of the moving block 102 is fixedly installed with a side rack 103, thereby driving the two sets of side racks 103 to move away from each other. The bottom surface of the top of the frame 1 is fixedly installed with a bottom block 104. The arc-shaped inner wall of the bottom end of the bottom block 104 is rotatably connected to the arc-shaped outer wall of the rotating shaft 105. Side gears 106 are fixedly installed on the front and rear external sides of the rotating shaft 105, and the side gears 106 mesh with the side rack 103. A central gear 107 is fixedly installed in the middle of the rotating shaft 105. An L-shaped frame 108 is fixedly installed on the lower top surface of the frame 1. A slide rail 109 is fixedly installed on the inner wall of the L-shaped frame 108. A slider 1010 is slidably installed inside the slide rail 109. A central rack 1011 is fixedly installed on the outer wall of the slider 1010. The central gear 107 meshes with the central rack 1011. Further, the servo hydraulic cylinder 4, side mold 5, rotating shaft 105, central gear 107, L-shaped frame 108, slide rail 109, slider 1010, and central rack 1011 are all connected. Two sets of racks 1011 and square slots 1012 are provided, and both sets of the above structures are mirror images of each other at the left and right ends of the frame 1 with the horizontal centerline in the front-rear direction as the axis of symmetry, so as to make the ejection of the workpiece more stable. Furthermore, two sets of elongated slots 101, moving blocks 102, side racks 103, bottom blocks 104, and side gears 106 are provided on the outer side of each slider 1010, and both sets of the above structures are symmetrically arranged at the front and rear ends of the frame 1 with the horizontal centerline in the left-right direction as the axis of symmetry, so as to cooperate with the side gears 106 on the left and right sides of the frame 1 to make the rotating shaft 105 on the left side of the frame 1 rotate counterclockwise inside the bottom block 104. This causes the central gear 107 on the left side of the frame 1 to rotate counterclockwise; at the same time, the rotating shaft 105 on the right side of the frame 1 rotates clockwise inside the base block 104, causing the central gear 107 on the right side of the frame 1 to rotate clockwise. This, in conjunction with the L-shaped frame 108, causes the two sets of central racks 1011 to move upwards simultaneously, thereby driving the two sets of sliders 1010 to slide upwards simultaneously inside the corresponding slide rails 109. A through square groove 1012 is provided at the top of the frame 1, located directly above the L-shaped frame 108, so that the sliders 1010 pass through the square groove 1012, thereby lifting the workpiece and enabling better and timely demolding of the workpiece.

[0023] Please see Figure 4 , Figure 9 , Figure 10In one embodiment of the present invention, the adsorption assembly 11 includes a piston rod 111. The piston rod 111 is fixedly installed at the bottom of the slider 1010. The piston rod 111 passes through the bottom of the L-shaped frame 108. Further, when the slider 1010 moves upward, it drives the piston rod 111 to move upward inside the air cylinder 112. The air cylinder 112 is fixedly installed at the bottom of the L-shaped frame 108. The arc-shaped outer wall of the bottom end of the piston rod 111 fits against the inside of the air cylinder 112. Further, the bottom end of the three-headed branch pipe 113 is fixedly connected to the arc-shaped side wall of the bottom end of the air cylinder 112. The side wall of the locking block 114 is fixedly installed on the outer wall of the bottom end of the L-shaped frame 108. The arc-shaped inner wall of the end of the locking block 114 away from the L-shaped frame 108 is fixedly connected to the arc-shaped outer wall of the top end of the three-headed branch pipe 113. The top end of the three-headed branch pipe 113 is fixedly connected to the arc-shaped outer wall of the top end of the three-headed branch pipe 113. The bottom of the telescopic air pipe 115 is fixedly connected, and the top of the telescopic air pipe 115 is fixedly installed inside the top of the slider 1010. This works in conjunction with the three-head branch pipe 113, the locking block 114, and the telescopic air pipe 115 to draw the airflow at the top of the telescopic air pipe 115 downward, thereby creating a suction force on the bottom of the workpiece. This makes the workpiece more stable during the lifting process. Furthermore, there are two sets of piston rod 111, air cylinder 112, three-head branch pipe 113, locking block 114, and telescopic air pipe 115 on the outside of a single slider 1010. Both sets of the above structures are mirrored at the left and right ends of the frame 1 with the horizontal centerline in the front-back direction of the frame 1 as the mirror axis. The three-head branch pipe 113 can prevent the telescopic air pipe 115 from interfering with the movement of the central gear 107 and the central rack 1011.

[0024] Please see Figure 4 , Figure 6 , Figure 9 , Figure 10In one embodiment of the present invention, the stabilizing mechanism 12 includes a U-shaped block 121. The U-shaped block 121 is fixedly mounted on the outer wall of the slider 1010 in the front-rear direction. A rotating rod 122 is fixedly mounted on the inner wall of the bottom end of the U-shaped block 121. A sliding rod 123 is rotatably mounted on the outside of the rotating rod 122. Further, a torsion spring 124 is sleeved on the outer side of the rotating rod 122. One end of the torsion spring 124 abuts against the outer wall of the bottom end of the sliding rod 123, and the other end abuts against the inner wall of the U-shaped block 121. A roller 125 is rotatably mounted inside the top end of the sliding rod 123. Limiting plates 126 are fixedly mounted on the outer wall of the top end of the L-shaped frame 108 in the front-rear direction to constrain the rotation direction of the sliding rod 123 when it moves downwards. Further, the U-shaped block 121 on the outer side of a single slider 1010... 1. Two sets of rotating rod 122, sliding rod 123, torsion spring 124, roller 125, and limiting plate 126 are provided. Both sets of the above structures are mirror images of the horizontal centerline in the left-right direction of the slider 1010 at the front and rear ends of the slider 1010, so as to make the ejection of the workpiece more stable. Furthermore, when the slider 1010 moves upward, it drives the U-shaped block 121 to move upward synchronously. In conjunction with the torsion spring 124 and the limiting plate 126, the bottom ends of the two sets of sliding rods 123 on the outside of the single slider 1010 rotate on the outside of the rotating rod 122, forming a V-shape. This drives the two sets of rollers 125 to roll at the bottom of the workpiece, which can effectively prevent the workpiece from tipping over during ejection, thus making the whole process more stable.

[0025] Please see Figure 6 , Figure 8In one embodiment of the present invention, an auxiliary component 13 is provided at the bottom of the support 2. The auxiliary component 13 includes an L-shaped block 131. An L-shaped block 131 is fixedly installed on the outer wall of the top of the slide rod 123. A short groove 132 is opened at the top of the frame 1. The short groove 132 and the slide rod 123 are located in the same vertical plane. A square block 133 is fixedly installed inside the short groove 132. The arc-shaped inner wall of the center of the square block 133 slides against the arc-shaped outer wall of the round rod 134. Further, an arc-shaped block 135 is fixedly installed at one end of the round rod 134 near the slide rod 123. A retaining spring 136 is sleeved on the outside of the round rod 134. One end of the retaining spring 136 is fixedly connected to... The outer wall of the block 133 facing the slide bar 123 is fixedly connected to the outer wall of the arc-shaped block 135 at the other end of the spring 136. Furthermore, when the slider 1010 moves upward, it cooperates with the slide bar 123 to cause the L-shaped block 131 to move upward away from the arc-shaped block 135. This, in conjunction with the short groove 132 and the block 133, causes the spring 136 to release its elastic potential energy and recover its deformation from a compressed state. This causes the round rod 134 to slide towards the slide bar 123. Furthermore, a fixing block 137 is fixedly installed at the end of the round rod 134 away from the slide bar 123, and a spring rod 138 is fixedly installed at the bottom of the short groove 132. The top of the spring rod 138 is fixedly connected to the bottom of the inclined block 139, which is located directly below the fixed block 137. The outer wall of one inclined side of the inclined block 139 faces the arc-shaped block 135, so that when the fixed block 137 moves towards the inclined block 139, it can drive the inclined block 139 downwards, thereby causing the fixed block 137 to move away from the top of the inclined block 139 in the same direction. This, combined with the release of elastic potential energy by the spring rod 138, allows the inclined block 139 to recover its deformation from a compressed state, causing the inclined block 139 to move upwards. This will strike the workpiece, allowing it to leave the mold more effectively and reducing the impact of adhesion on subsequent demolding. Conversely, when the slider 101... When the slider moves downward, the fixed block 137 slides on the outer wall of the inclined block 139, which compresses the spring rod 138 and causes the inclined block 139 to return to the inside of the short groove 132 for reset. Furthermore, two sets of L-shaped blocks 131, short grooves 132, square blocks 133, round rods 134, arc blocks 135, clamping springs 136, fixed blocks 137, spring rods 138 and inclined blocks 139 are provided on the outside of a single slider 1010. Both sets of the above structures are mirrored at the front and rear ends of the slider 1010 with the horizontal center line in the left and right direction of the slider 1010 as the mirror axis, so as to improve the demolding effect of the workpiece.

[0026] Working principle: First, the servo hydraulic cylinder 4 is activated via the control console 3, causing the two side molds 5 to approach each other until they are pressed together. Then, the servo hydraulic press 6 is activated to drive the upper mold 7 downward. Next, the servo heater 8 is activated, thus completing the die casting and heat forming of the workpiece. After the operation is completed, the control console 3 is reversed to move the two side molds 5 away from each other. Furthermore, when the two side molds 5 move away from each other, the two sets of moving blocks 102 move away from each other within the long groove 101, thereby causing the two sets of side racks 103 to move away from each other. This, in turn, cooperates with the side gears 106 on the left and right sides of the frame 1, causing the rotating shaft 105 on the left side of the frame 1 to rotate counterclockwise within the bottom block 104, thereby causing the middle gear on the left side of the frame 1 to rotate counterclockwise. Wheel 107 rotates counterclockwise; simultaneously, the shaft 105 on the right side of the frame 1 rotates clockwise inside the base block 104, causing the central gear 107 on the right side of the frame 1 to rotate clockwise. This, in conjunction with the L-shaped frame 108, causes the two sets of central racks 1011 to move upwards simultaneously, thereby driving the two sets of sliders 1010 to slide upwards simultaneously inside the corresponding slide rails 109. The sliders 1010 pass through the square grooves 1012, thus lifting the workpiece and enabling better and timely demolding. Furthermore, when the sliders 1010 move upwards, they drive the piston rod 111 to move upwards inside the air cylinder 112, thereby cooperating with the three-headed branch pipe 113, the clamping block 114, and the telescopic air pipe 115 to extend the telescopic air pipe 115. The airflow at the top is drawn downwards, creating a suction force on the bottom of the workpiece, thus making the workpiece more stable during the lifting process. Furthermore, when the slider 1010 moves upwards, it drives the U-shaped block 121 to move upwards synchronously. This, in conjunction with the torsion spring 124 and the limiting plate 126, causes the bottom ends of the two sets of sliding rods 123 on the outer side of the single slider 1010 to rotate outside the rotating rod 122, forming a V-shape. This drives the two sets of rollers 125 to roll at the bottom of the workpiece, effectively preventing tipping during the workpiece ejection process and making the entire process more stable. Furthermore, when the slider 1010 moves upwards, it, in conjunction with the sliding rods 123, causes the L-shaped block 131 to move upwards away from the arc-shaped block 135, from... The short groove 132 and the square block 133 work together to allow the spring 136 to release its elastic potential energy and recover its deformation from the compressed state. This causes the round rod 134 to slide towards the slide rod 123, which in turn causes the fixed block 137 to move away from the top of the inclined block 139. This, in conjunction with the spring rod 138, releases its elastic potential energy and recovers its deformation from the compressed state, causing the inclined block 139 to move upward and strike the workpiece. This helps the workpiece to leave the mold more easily and reduces the impact of adhesion on subsequent demolding. Conversely, when the slider 1010 moves downward, the fixed block 137 slides on the outer wall of the inclined surface of the inclined block 139, which compresses the spring rod 138 and causes the inclined block 139 to return to the inside of the short groove 132 for reset.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
