Description

Technical Field

[0001] The present invention relates to the technical field of aluminum alloy production, and particularly relates to a device for forming and demolding a high-strength die-cast aluminum alloy. Background Art

[0002] Die casting is a process of metal smelting and processing. It is a casting method in which a molten alloy liquid is filled into the cavity of a steel mold at high speed under high pressure, and the alloy liquid solidifies under pressure to form a casting. According to the specific structure and shape of the part, a corresponding mold is made, and then a fluid liquid is poured into the die-casting cavity. After subsequent condensation and demolding procedures, the formed casting can be taken out. The demolding method of existing die-casting equipment is through ejector rods arranged in the mold. When the mold moves, the ejector rods in the corresponding mold will extend out of the mold and directly act on the outer wall of the casting, and the position of the ejector rods usually remains unchanged. However, the adhesion force between the casting and the inner wall of the mold is random. For example, if the release agent is sprayed unevenly, the ejector rods at fixed positions are likely to cause imprints on the surface of the die-cast part during the demolding process, affecting the product quality. In view of this, we propose a device for forming and demolding a high-strength die-cast aluminum alloy. Summary of the Invention

[0003] Aiming at the above-mentioned shortcomings of the existing technology, the present invention provides a device for forming and demolding a high-strength die-cast aluminum alloy, which can effectively solve the problem that the demolding method of existing die-casting equipment is through ejector rods arranged in the mold. When the mold moves, the ejector rods in the corresponding mold will extend out of the mold and directly act on the outer wall of the casting, and the position of the ejector rods usually remains unchanged. However, the adhesion force between the casting and the inner wall of the mold is random. For example, if the release agent is sprayed unevenly, the ejector rods at fixed positions are likely to cause imprints on the surface of the die-cast part during the demolding process, affecting the product quality.

[0004] To achieve the above object, the present invention is realized through the following technical solutions: The present invention provides a device for forming and demolding a high-strength die-cast aluminum alloy, including a detachably connected mold A and mold B.

DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0015] The present invention will be further described below in conjunction with the embodiments.

[0016] Refer to the attached Figures 1-7 As shown in, a high-strength die-casting aluminum alloy forming demolding processing device includes a detachably connected mold A100 and a mold B200. When the two are in a fitted state, a die-casting cavity is formed in the middle of the two. A casting pipe 110 for casting aluminum solution is provided at the lower side of the mold A100. In the present application, the die-casting is achieved by placing the aluminum solution in the casting pipe 110, and then moving the driving shaft movably connected in the casting pipe 110 to one side, so that the aluminum solution in the casting pipe 110 is pushed to the internal position of the die-casting cavity to achieve die-casting. It should be noted that in the die-casting link, a stable overlap is maintained between the corresponding mold A100 and the mold B200, and a die-casting cavity is formed in the middle of the two. After the aluminum solution is pushed into the die-casting cavity, it is pressurized by the driving shaft. After a certain period of time, the temperature is reduced and the corresponding aluminum profile can be die-cast.

[0017] Before die casting, in order to ensure the high efficiency of subsequent demoulding, a demoulding agent needs to be evenly sprayed on the inner wall of the die casting cavity. The existing spraying method is manual spraying, which has low efficiency. However, in this application, lap joints 210 are fixedly installed on both sides of the die B200. A lap plate 500 is movably connected to the frame body 400. A spray head pipe 510 for spraying the demoulding agent is fixedly connected to the lap plate 500. When the die B200 approaches the die A100, the spray head pipe 510 will be withdrawn from between the die A100 and the die B200. Moreover, an inclined surface A211 is provided on the side wall of the lap joint 210, and an inclined surface B501 is provided on the lap plate 500. The inclined surface A211 and the inclined surface B501 are in sliding fit. When the die A100 approaches the die B200, relative sliding occurs between the corresponding lap joint 210 and the lap plate 500, and the lap plate 500 drives the spray head pipe 510 to be withdrawn from the die casting cavity.

[0018] During the spraying process of the demoulding agent, when the die A100 approaches the die B200, as an implementation method, in this application, an external driving rod can be used to drive the die B200 to approach the die A100. The position of the die A100 is relatively fixed. When the die B200 approaches the die A100, the lap joint 210 that remains relatively fixed to the die B200 will also move synchronously. Correspondingly, a lap plate 500 is movably connected to the frame body 400. Moreover, an inclined surface A211 is provided on the side wall of the lap joint 210, and an inclined surface B501 is provided on the lap plate 500. The inclined surface A211 and the inclined surface B501 are in sliding fit. When the external driving rod operates, the corresponding two lap plates 500 will move in the direction away from each other, and the spray head pipes 510 fixedly installed on the lap plates 500 will also move synchronously. During spraying, the spray head pipes 510 are inside the die casting cavity. After spraying is completed, the corresponding spray head pipes 510 will be withdrawn from the die casting cavity to ensure the stable lap between the die A100 and the die B200.

[0019] It is worth noting that in the present application, the end of the nozzle tube 510 is set as a rubber head. When the die-casting is completed, in the demoulding process, the corresponding mold A100 will move away from the mold B200, and the two lap plates 500 will approach each other. In this process, the end of the nozzle tube 510 will contact the outside of the formed aluminum profile. On the one hand, the rubber head will not damage the outer wall of the aluminum profile. At the same time, the contact between the rubber head and the aluminum profile can also assist in demoulding. In addition, the piston tube A410 is fixedly connected to the outer wall of the frame 400, and the piston rod A is movably connected inside the piston tube A410. The piston rod A is fixedly connected to the outer wall of the lap block 210, and the lap plate 500 is elastically connected to the outer wall of the frame 400 through the spring B520. By setting the spring B520, the overlapping plate 500 can be reset, and the nozzle pipe 510 will be located between the middle of the mold A100 and the mold B200 again, so as to realize the subsequent spraying of the release agent on the inner wall of the die-casting cavity.

[0020] In the die-casting process, when mold A100 and mold B200 are overlapped and a die-casting cavity is formed between the middle parts of the two, there will be gas in the corresponding die-casting cavity. In the subsequent die-casting process, when the aluminum solution is squeezed into the die-casting cavity under the action of the external driving shaft, part of the air in the die-casting cavity will be squeezed into the aluminum solution, and there is a certain amount of hydrogen in the aluminum solution itself. In this case, it is more important to fully discharge the gas in the die-casting cavity. If it is not discharged in time, more bubbles will be formed on the surface during the subsequent aluminum profile molding, affecting the quality; Therefore, the present application also includes a scheme for exhausting the air in the die-casting cavity, specifically, it also includes a sleeve 220 fixedly installed in the middle of the outer wall of the mold B200, a slide groove 222 is provided inside the sleeve 220, a cylindrical member 600 is movably connected inside the slide groove 222, the outer end of the cylindrical member 600 is elastically connected to the outer wall of the sleeve 220 through a spring C610, the inner end surface of the cylindrical member 600 and the cavity wall of the die-casting cavity are in the same plane, and it also includes a resistance tube 700 movably connected inside the cylindrical member 600, a through groove is provided inside the resistance tube 700, and a plurality of air outlet holes 701 are provided in an annular structure at the end of the through groove, the resistance tube 700 passes through the cylindrical member 600 and extends to the outside where a connecting tube 710 is fixedly installed, and the connecting tube 710 is kept in communication with the suction end of the external air pump; When mold A100 and mold B200 are in an overlapping state, and before die-casting, the position of the resistance tube 700 is adjusted, specifically, the resistance tube 700 is moved toward the position of mold A100, so that the end of the resistance tube 700 contacts the outer wall of the movable plate 320, and the end face of the movable plate 320 is in the same plane with the inner wall of the die-casting cavity. When the end of the resistance tube 700 contacts the outer wall of the movable plate 320, the corresponding air outlet 701 opened at the end position of the resistance tube 700 will remain connected with the die-casting cavity, and through an external air pump, the internal through groove of the resistance tube 700 is connected with the air pump and the air outlet 701, the gas in the die-casting cavity can be extracted and a relative vacuum state can be formed, thereby reducing the number of bubbles on the surface of the aluminum profile in the subsequent die-casting molding process and improving the die-casting quality. When the die-casting cavity is evacuated, the resistance tube 700 is reset to prepare for die-casting.

[0021] When the die-casting is completed, demoulding operation is required. In order to improve the demoulding efficiency, in this application, demoulding is assisted in mold A100 and mold B200 respectively. Specifically, on the one hand, the method of assisting demoulding on mold A100, in this application, includes two frames 400 sleeved on the outer side of mold B200, and a piston tube A410 is arranged on the frame 400; a cavity A101 is opened in the mold A100, and a moving part 300 is movably connected in the cavity A101, and a movable groove 301 is opened in the movable part 300, and a movable plate 320 is movably connected in the movable groove 301. When mold A100 is separated from mold B200, the gas in the piston tube A410 enters the movable groove 301 and drives the movable plate 320 to move toward the die-casting cavity to assist demoulding; specifically, in the demoulding process, when mold A100 is opened, the movable plate 320 is moved toward the die-casting cavity to assist demoulding; specifically, in the demoulding process, when mold A100 is opened, the movable plate 320 is moved toward the die-casting cavity to assist demoulding; specifically, in the demoulding process, when mold A100 is opened, the movable plate 320 is moved toward the die-casting cavity to assist demoulding; specifically, in the demoulding process, when mold A100 is opened, the movable plate 320 is moved toward the die-casting cavity to assist demoulding; When the die casting die 100 is separated from the die casting die B200, the gas in the corresponding piston tube A410 enters the cavity A101 through the hose 120. At this time, the moving part 300 movably connected in the cavity A101 will move toward the side away from the die casting cavity, and the corresponding gas will enter the inner position of the die casting cavity from the outer wall of the moving plate 320, and inflate the contact surface between the aluminum profile and the die casting cavity. At this time, the aluminum profile and the die casting cavity are separated by the gas pressure. Furthermore, in the present application, an inclined surface 102 is provided at a position on the cavity A101 close to the die-casting cavity. The moving member 300 is slidably engaged with the cavity A101. The outer wall of the moving member 300 is elastically connected to the inner wall of the cavity A101 through a spring A310. The cavity A101 is kept in communication with the hose 120 through a connection groove 103 opened on the mold A100, and the hose 120 is in communication with the piston tube A410; the movable groove 301 is in communication with the cavity A101 through a round hole. The outer wall of the moving plate 320 is slidably engaged with the inner wall of the movable groove 301, and the moving plate 320 separates the cavity A101 from the movable groove 301; the outer wall of the moving plate 320 is on the same plane as the cavity wall of the die-casting cavity on the mold A100. When the gas flows from the piston tube A410 through the hose 120 into the cavity A101, the moving member 300 will move toward the side away from the die-casting cavity, and correspondingly, the moving plate 320 will press the casting, and at the same time, the gas will blow toward the die-casting cavity along the inclined surface 102.

[0022] Specifically, when the gas enters the cavity A101, the moving plate 320 movably connected to the inner position of the moving member 300 will move toward the direction of the mold B200. The end face of the moving plate 320 is on the same horizontal plane as the cavity wall of the die-casting cavity before demolding. When the moving plate 320 moves toward the direction of the mold B200, the moving plate 320 will apply an external force to the aluminum profile to achieve demolding. It should be noted that when the gas enters the die-casting cavity along the inclined surface 102, the cavity A101 can be depressurized. Under the action of the spring A310, the moving member 300 will reset, and correspondingly, the moving plate 320 will be in a state close to vibration. This knocking method can effectively improve the demolding efficiency.

[0023] Regarding the demolding process, another way to improve the demolding efficiency is provided in the present application. Specifically, an arc block 620 is symmetrically fixedly installed on the outer end of the cylindrical member 600; and a piston tube B800 is arranged on one side of the mold B200, and a piston rod B is movably connected inside the piston tube B800. The piston rod B extends through the piston tube B800 to the outside and is fixedly connected with a cross frame 810. An arc surface 811 is provided at the lower end of the cross frame 810, and the arc surface 811 is slidably matched with the arc block 620, and the piston tube B800 is also connected to the hose 120. Specifically in the present application, when mold A100 is separated from mold B200, the gas in the corresponding piston tube A410 will enter the internal position of the piston tube B800 through the hose 120. At this time, the piston rod B movably connected in the piston tube B800 will drive the cross frame 810 to move synchronously. In combination with the sliding fit between the arc surface 811 and the arc block 620, the corresponding cylindrical part 600 will slide in the slide groove 222, so that the end of the cylindrical part 600 will contact the outer wall of the aluminum profile. In combination with the movable plate 320 acting on the aluminum profile, the force acting on the aluminum profile can be increased, thereby improving the demolding effect.

[0024] Furthermore, in the present application, a ring fixedly mounted on the outer wall of the resistance tube 700 is also included, the ring is slidably matched with the sliding groove 601 provided in the cylindrical member 600, and the ring is elastically connected to the inner wall of the sliding groove 601 through the spring D720. A contact switch 221 is also included, which is arranged on the outer wall of the sleeve 220, and the contact switch 221 is used to control the power-on state of the spring D720; when the outer wall of the cylindrical member 600 contacts the contact switch 221, the spring D720 is powered; when the spring D720 is in the power-on state, it will shrink, and the resistance tube 700 will extend out of the cylindrical member 600 to assist in demoulding. When the cylindrical member 600 is acted upon by the cross frame 810, it will move along the axial direction of the cylindrical member 600, and the corresponding contact switch 221 will be intermittently contacted, thereby realizing that the resistance tube 700 moves out of the cylindrical member 600 and acts on the aluminum profile, thereby improving the demoulding effect.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
