Description

Technical Field

[0001] The invention relates to the technical field of production and processing of aluminum alloy products, in particular to a die-casting mold for producing aluminum alloy products. Background Art

[0002] Aluminum alloy products refer to various items made of aluminum alloy as the main material. Aluminum alloy has the advantages of light weight, high strength, corrosion resistance, good thermal conductivity and electrical conductivity, so it is widely used in many fields such as aerospace, automobile, electronics, construction, etc. Common aluminum alloy products include automobile wheels, aluminum alloy doors and windows, electronic product housings, etc. In the production and processing process, aluminum alloy products can be made by a variety of methods, including casting, extrusion, forging, etc. Among them, die casting is a commonly used aluminum alloy forming process, which is particularly suitable for the production of parts with complex shapes and high precision. The die casting process usually uses high pressure to inject molten aluminum alloy into the mold, and then take out the finished product after it cools and forms.

[0003] In the prior art, during the use of die-casting molds for the production of aluminum alloy products, the movable mold is generally driven by a hydraulic system to move and cooperate with the static mold to achieve mold closing. During die-casting, liquid metal is injected into the cavity of the die-casting mold under high pressure. When the equipment fails and the high-pressure impact is too large, the mold will accidentally separate under the action of pressure, destroying the mold closing state, easily causing metal liquid leakage, incomplete filling, and defective products, affecting the strength and appearance of the product.

[0023] In this embodiment, when in use, the laser distance sensor 219 and the forward and reverse motor 303 are both electrically connected to the external control system. When the first mold 104 and the second mold 105 are molded together, the first locking plate 201 and the second locking plate 202 will be driven to close together. Under the action of the buffer pad 205, it is helpful to reduce the impact of the first locking plate 201 and the second locking plate 202. When the first locking plate 201 and the second locking plate 202 are closed, multiple L-shaped locking plates 204 will be inserted into the locking grooves 207 at corresponding positions, so that the connection hole 221 is aligned with the locking hole 203. At the same time, the end of the L-shaped rod 213 with the ball 223 is located above the inclined slide groove 314, and then the forward and reverse motors are started through the external control system. 303, the driving wheel 304 is driven to rotate by the rotation of the output end of the forward and reverse motor 303, and then the chain 305 meshing with it is driven to rotate on the outer surface of the arc plate 306, and the chain 305 is limited by the arc plate 306 to facilitate the chain 305 to rotate better. Under the rotation of the chain 305, multiple driven wheels 307 are driven to rotate together, and at the same time, the two ends of multiple support rods 310 are respectively rotated in the corresponding annular grooves 311, which is convenient for the driven wheels 307 to rotate smoothly. When the multiple driven wheels 307 rotate, the internal lead screw 308 is driven to rotate spirally and move upward, and the multiple T-shaped rods 309 are pushed upward, and the multiple L-shaped push blocks 312 are further pushed out from the embedded grooves 208 and gradually enter the corresponding L-shaped locking templates 2 04, the end of the L-shaped rod 213 with the ball 223 enters the inclined slot 314, and the ball 223 contacts the bottom surface of the inclined slot 314. As the L-shaped locking plate 204 continues to move upward, the ball 223 rotates in the inclined slot 314 and the rotating slot 222, and at the same time pushes the L-shaped rod 213 to move, and then pushes the movable block 215 to slide in the L-shaped locking plate 204, and further pushes the locking rod 217 through the connecting hole 221 into the locking hole 203. Under the movement of the movable block 215, the reset spring 216 is pulled to expand. When the forward and reverse motor 303 is automatically closed, the top of the L-shaped push block 312 contacts the top surface of the L-shaped locking plate 204, and the ball 223 moves to the inclined slot. At the lowest point inside 314, the locking rod 217 enters the locking hole 203. Through the cooperation of the locking rod 217 and the locking hole 203, the L-shaped locking plate 204 is fixed in the locking groove 207, and the first locking plate 201 and the second locking plate 202 are further fixed together, so as to fix the first mounting seat 101 and the second mounting seat 102 after the mold is closed. Through the cooperation of the moving component 3 and the locking component 2, the locking effect is achieved, and additional locking force is provided for the first mold 104 and the second mold 105 to ensure that the mold can be tightly closed during the die-casting process, resist the internal high pressure, keep the mold in a stable closed state during the working process, and prevent the mold from accidentally opening under high pressure. The L-shaped locking plate 204 is provided with four,They are respectively located at the dead angles of the outer surface of the first mounting seat 101. When clamping the mold, the clamping force can be applied more evenly to avoid the influence of uneven local force on the clamping effect. This solves the problem that when the die-casting mold for the production of aluminum alloy products is used, when the equipment fails and the high-pressure impact is too large, the mold will be accidentally separated under the pressure, which will destroy the clamping state, easily cause the leakage of metal liquid, incomplete filling, and produce defective products, affecting the strength and appearance of the product.

[0024] Embodiment 2: Figure 1-Figure 2 , Figure 4 and Figure 9-12 As shown, a locking assembly 2 is arranged on the outer surface of the mold assembly 1, and a moving assembly 3 is arranged at the bottom of the locking assembly 2. The moving assembly 3 is used to connect the locking assembly 2 together, and the locking assembly 2 is used to strengthen the firmness of the mold when the mold is closed. Rolling balls 223 are movably embedded in the interiors of the plurality of rotating grooves 222. A buffer pad 205 is fixedly connected to the top of the second locking template 202. A plurality of movable holes 206 are provided on the top of the buffer pad 205. Two detection holes 209 are provided on the top of the buffer pad 205. A first detection groove 210 is provided on the top of the second locking template 202 near one of the detection holes 209. A second detection groove 211 is provided on the top of the second locking template 202 near the other detection hole 209. Two mounting grooves 218 are provided at the bottom of the first locking template 201, and laser ranging sensors 219 are provided inside the two mounting grooves 218.

[0025] In this embodiment, when in use, when the first mold 104 and the second mold 105 are molded together, the first locking plate 201 and the second locking plate 202 are driven to gradually close, the mold is locked, and the two laser distance measuring sensors 219 are started in advance. The two laser distance measuring sensors 219 correspond to the centers of the inner bottom surfaces of the first detection groove 210 and the second detection groove 211 respectively. The heights of the centers of the inner bottom surfaces of the first detection groove 210 and the second detection groove 211 are flush. The distances between the first detection groove 210 and the second detection groove 211 are respectively detected by the two laser distance measuring sensors 219, and the detected distance data are transmitted to the external control system in the form of electrical signals for identification and comparison. When the first locking plate 201 and the second locking plate 202 are aligned, the two laser distance measuring sensors 219 respectively detect the distances to the centers of the inner bottom surfaces of the first detection groove 210 and the second detection groove 211. At this time, the two distance data are the same, and the internal structures of the first detection groove 210 and the second detection groove 211 are different. Fig.11As shown, the inner wall of the second detection groove 211 is relatively flat, and the inner wall of the first detection groove 210 is relatively inclined. When the position of the first locking template 201 or the second locking template 202 is slightly deviated, the two laser ranging sensors 219 will be offset from the center of the inner bottom surface of the first detection groove 210 and the second detection groove 211. At this time, the two laser ranging sensors 219 will respectively detect the distance between the inner walls of the first detection groove 210 and the second detection groove 211. Since the internal structures of the first detection groove 210 and the second detection groove 211 are different, the two distance data detected at this time will also be different. Then the external control system will trigger the alarm system to remind the staff that the first mold 104 or the second mold 105 is slightly deviated and needs to be adjusted as soon as possible to prevent the mold from being slightly deviated and affecting the subsequent die-casting effect.

[0026] Embodiment 3: Figure 1-Figure 5 As shown, the mold assembly 1 includes a first mounting seat 101, a second mounting seat 102 is arranged at the bottom of the first mounting seat 101, a first mold 104 is arranged inside the first mounting seat 101, a casting pipe 103 is arranged inside the first mounting seat 101, a second mold 105 is arranged inside the second mounting seat 102, a mold base 106 is arranged inside the second mold 105, an insert 107 is arranged on the outer surface of the mold base 106, and a boss 108 is fixedly installed inside the insert 107 near the top.

[0027] In this embodiment, when in use, a boss 108 is provided inside the insert 107. The boss 108 is designed to be offset inward by 0.5 mm inside the insert 107. The insert 107 is located on the die base 106. During the die-casting process, the position of the insert 107 is prevented from being offset. When the first mold 104 and the second mold 105 are molded together, the boss 108 plays a limiting role. The top of the insert 107 has an R angle, such as Figure 5 As shown, the stress concentration phenomenon can be significantly reduced. The arc-shaped fillet shape allows the stress to be distributed more evenly, dispersing the stress concentrated at the sharp corners, thereby reducing the local stress peak. By increasing the R angle, it is helpful to reduce product cracking caused by stress concentration problems.

[0028] The effect and working principle of the whole mechanism are as follows: when the first mold 104 and the second mold 105 are closed, the first locking plate 201 and the second locking plate 202 will be driven to close together, and at the same time, multiple L-shaped locking plates 204 will be inserted into the locking grooves 207 at the corresponding positions. At this time, the connecting holes 221 are aligned with the locking holes 203, and then the forward and reverse motors 303 are started through the external control system to drive the driving wheel 304 and the chain 305 to rotate, and then drive the multiple driven wheels 307 to rotate together, and then drive the internal lead screw 308 to spirally rotate and move upward, and push the multiple T-shaped rods 309 to move upward, and further push the multiple L-shaped push blocks 312 out of the embedded grooves 208 and gradually enter the corresponding L-shaped locking plates 2 04, the end of the L-shaped rod 213 with the ball 223 enters the inclined slot 314, and the ball 223 contacts the bottom surface of the inclined slot 314. As the L-shaped locking plate 204 continues to move upward, the ball 223 rotates in the inclined slot 314 and the rotating slot 222, and at the same time pushes the L-shaped rod 213 to move, and then pushes the movable block 215 to slide in the L-shaped locking plate 204, and further pushes the locking rod 217 through the connecting hole 221 into the locking hole 203. Under the movement of the movable block 215, the reset spring 216 is pulled to expand. When the forward and reverse motor 303 is automatically closed, the top of the L-shaped push block 312 contacts the top surface of the L-shaped locking plate 204, and the ball 223 moves. To the lowest point inside the inclined slide groove 314, the locking rod 217 enters the locking hole 203, fixes the L-shaped locking plate 204 in the locking groove 207, and further fixes the first locking plate 201 and the second locking plate 202 together, so as to fix the first mounting seat 101 and the second mounting seat 102 after the mold is closed. Through the cooperation of the moving component 3 and the locking component 2, the locking effect is achieved, and additional locking force is provided for the first mold 104 and the second mold 105 to ensure that the mold can be tightly closed during the die-casting process, resist the internal high pressure, keep the mold in a stable closed state during the working process, and prevent the mold from accidentally opening under high pressure. Four L-shaped locking plates 204 are provided, which are respectively located at the first mounting seat 101 and the second mounting seat 102 after the mold is closed. At the dead angle of the outer surface of the mounting seat 101, during mold locking, the mold locking force can be applied more evenly to avoid local uneven force affecting the mold locking effect. The two laser distance measuring sensors 219 are started in advance. The two laser distance measuring sensors 219 correspond to the center of the inner bottom surface of the first detection groove 210 and the second detection groove 211 respectively. The height of the center of the inner bottom surface of the first detection groove 210 and the second detection groove 211 is flush. The two laser distance measuring sensors 219 detect the distance between the first detection groove 210 and the second detection groove 211 respectively, and transmit the detected distance data to the external control system in the form of electrical signals for identification and comparison. When the first locking plate 201 and the second locking plate 202 are aligned,The two laser distance measuring sensors 219 will respectively detect the distance to the center of the inner bottom surface of the first detection slot 210 and the second detection slot 211. At this time, the two distance data are the same. The internal structures of the first detection slot 210 and the second detection slot 211 are different, such as, Fig.11 As shown, the inner wall of the second detection groove 211 is relatively flat, and the inner wall of the first detection groove 210 is relatively inclined. When the position of the first locking template 201 or the second locking template 202 is slightly offset, the two laser distance sensors 219 will be offset from the center of the inner bottom surface of the first detection groove 210 and the second detection groove 211. At this time, the two laser distance sensors 219 will respectively detect the distance between the inner walls of the first detection groove 210 and the second detection groove 211. Since the internal structures of the first detection groove 210 and the second detection groove 211 are different, the two distance data detected at this time will also be different. Then the external control system will trigger the alarm system to remind the staff that a boss 108 is set inside the insert 107 to prevent the position of the insert 107 from shifting during the die-casting process. When the first mold 104 and the second mold 105 are molded together, the boss 108 plays a limiting role, and the top of the insert 107 has an R angle increased, such as Figure 5 As shown, stress concentration can be significantly reduced.

[0029] Among them, the first mold 104, the second mold 105, the laser ranging sensor 219 and the forward and reverse motor 303 are all existing technologies, and their components and operating principles are all public technologies, which will not be explained in detail here.
