[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.
[0038] Embodiment 1:
[0039] like Figures 1 to 9 As shown, an aluminum die-casting mold for a multi-sided thin-walled deep-cavity workpiece includes a workbench 1, a transposition roller 2, a support arm 3 and a positioning shaft 4.
[0040] A pair of slides 13 are installed on the workbench 1, wherein a slide rail 131 is slidably provided at the bottom of one of the slides 13, and the bottom of the slide rail 131 is installed on the workbench 1, and the other slide 13 is fixed on the workbench 1, and an extrusion plate 132 is installed on the surface of the pair of slides 13, and a first mold 133 and a second mold 134 are installed on the opposite surfaces of the two extrusion plates 132, respectively, and the first mold 133 and the second mold 134 are adapted, and a liquid injection pipe 14 is connected to the second mold 134, and a push rod 15 is movably inserted and inserted inside the first mold 133, and the end of the push rod 15 corresponds to the push block 121 installed on the workbench 1; the transposition roller 2 is rotatably installed at the bottom of the workbench 1, and a driving motor 211 is installed at the rotation center of the transposition roller 2, and a combination groove 22 is opened on the surface of the transposition roller 2 The combined groove 22 includes a feed groove 221 and an extrusion groove 222. The extrusion groove 222 is a spiral groove, and the feed groove 221 is an arc groove. A synchronous bracket 231 is slidably arranged on the combined groove 22, and the end of the synchronous bracket 231 is connected to the side wall of the extrusion plate 132 on which the first mold 133 is installed. In the later process of demolding, the driving motor drives the transposition roller to reverse, and the spiral extrusion groove on the transposition roller drives the entire synchronous bracket to move outward, pulling the extrusion plate on which the first mold is installed to separate from the second mold, thereby achieving the purpose of mold separation. When the extrusion plate and the first mold move to a certain extent, the ejector rod and the ejector block of the first mold and the side wall of the extrusion plate are squeezed and contacted with each other, and then the ejector rod can move in the opposite direction, thereby ejecting the internal workpiece, thereby achieving the purpose of demolding.
[0041] The support arm 3 is installed on both sides of the workbench 1, and a storage box 311 is installed on the support arm 3. A transmission cover 32 is installed at the bottom of the storage box 311, and nozzles 321 are installed on both sides of the transmission cover 32; the positioning shaft 4 movably passes through the support arm 3, and the positioning shaft 4 and the transmission cover 32 are connected to each other. A rocker arm 411 is installed at the end of the positioning shaft 4, and a guide block 412 is installed on the surface of the rocker arm 411. The guide block 412 is slidably connected with a wavy guide rail 413 installed on the side wall of the support arm 3, and a vertical rod 422 is rotatably installed at the bottom of the positioning shaft 4, and an extrusion rod 424 is installed at the end of the vertical rod 422. The end of the extrusion rod 424 is inserted into the notch 425 opened at the bottom of the transposition roller 2. After demoulding is completed, the synchronous bracket slides on the discharge chute. At this time, the transposition roller continues to rotate, and the position of the synchronous bracket does not change. However, the position of the notch at the bottom of the transposition roller changes. The notch can push the extrusion rod to move downward, and the extrusion rod drives the vertical rod to slide downward. The vertical rod pulls the positioning axis to move downward at this time, and the positioning axis drives the entire transmission cover to move to the gap between the first mold and the second mold, and the nozzle is aligned with the first mold and the second mold, which is convenient for the later application of the release agent. When the positioning axis slides downward, the rocker arm and guide block on the positioning axis slide on the wavy guide rail, and then the rocker arm will deflect, and the positioning axis rotates synchronously, and then the position of the nozzle swings at this time, ensuring that the release agent sprayed by the nozzle can be more evenly attached to the mold core. In this way, after demoulding is completed, the nozzle can be automatically driven to move, and the release agent can be evenly sprayed on the mold core, making the mold more convenient to use and more reliable to operate.
[0042] like Figures 1 to 9 As shown, in a specific embodiment, four supporting legs 11 are installed at the bottom of the workbench 1, and reinforcing ribs 111 are installed between adjacent supporting legs 11.

A pair of side panels 12 are installed on the top of the workbench 1, and one of the side panels 12 and the side wall of the top block 121 are connected to each other. A discharge hole 16 is opened on the workbench 1, and the discharge hole 16 is used to discharge the workpiece.
[0043] like Figures 1 to 9 As shown, further, a hydraulic push rod 142 is installed on the side plate 12 away from the top block 121, and the side wall of the output end of the hydraulic push rod 142 movably penetrates the side wall of the side plate 12, and an extrusion piston 143 is installed on the output end of the hydraulic push rod 142, and the extrusion piston 143 is movably plugged into the inner wall of the injection pipe 14, and an input bucket 141 is installed on the top of the injection pipe 14, and the input bucket 141 is conical. The aluminum liquid is poured into the injection pipe 14 through the input bucket 141, and the poured aluminum liquid flows into the cavity between the first mold 133 and the second mold 134 through the injection pipe 14, and then the hydraulic push rod 142 is started, and the extrusion piston 143 is pushed to slide by the hydraulic push rod 142, so that the aluminum liquid inside the injection pipe 14 is completely squeezed into the internal cavity.
[0044] Embodiment 2:
[0045] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a synchronization plate 151 is installed at the end of the push rod 15, a synchronization rod 154 is installed on the synchronization plate 151, and a guide ball 155 is installed at the end of the synchronization rod 154, the guide ball 155 corresponds to the push block 121, a positioning bracket 152 is inserted into the side wall of the synchronization rod 154, the positioning bracket 152 is connected to the side wall of the extrusion plate 132, and a positioning spring 153 is sleeved on the push rod 15, one end of the positioning spring 153 is clamped on the synchronization plate 151, and the other end of the positioning spring 153 is clamped on the side wall of the extrusion plate 132. When the extrusion plate 132 and the first mold 133 move to a certain extent, the synchronization rod 154 and the top block 121 on the side walls of the first mold 133 and the extrusion plate 132 are squeezed and contacted with each other, and then the synchronization rod 154 can move in the opposite direction, and the synchronization rod 154 pushes the synchronization plate 151 to slide, and the synchronization plate 151 pushes the four top rods 15 to slide outward, thereby ejecting the internal workpiece to achieve the purpose of demolding, and during the sliding of the synchronization plate 151, the positioning spring 153 can be squeezed, and the subsequent resetting is facilitated by the positioning spring 153.
[0046] like Figures 1 to 9 As shown, in a specific embodiment, a bearing is clamped on the rotating shaft of the transposition roller 2, and a bearing seat 21 is clamped on the outer wall of the bearing. The bearing seat 21 is welded and set at the bottom of the workbench 1, and the side wall of the bearing seat 21 is connected to the housing of the driving motor 211. A limit rod 233 is clamped on the inner wall of the bearing seat 21, and a guide slider 23 is slidably set on the limit rod 233. An extrusion spring 234 is sleeved on the limit rod 233, and the extrusion spring 234 is clamped on the side wall of the bearing seat 21 and the side wall of the guide slider 23 respectively. The bottom of the guide slider 23 is slidably connected to the combination groove 22, and the top of the guide slider 23 is slidably connected to the synchronous bracket 231. The synchronous bracket 231 is L-shaped, and the synchronous bracket 231 is slidably set on the synchronous slide groove 232 opened on the surface of the workbench 1. The driving motor 211 drives the transposition roller 2 to rotate. At this time, the transposition roller 2 rotates on the bearing seat 21, and then the position of the combined groove 22 on the transposition roller 2 changes, and the spiral extrusion groove 222 on the transposition roller 2 drives the entire guide slider 23 to move outward, and the guide slider 23 slides along the limit rod 233, and compresses the extrusion spring 234 during sliding, so that the resetting operation can be facilitated later by the extrusion spring 234. When the guide slider 23 slides, it can drive the synchronous bracket 231 to move outward, and the synchronous bracket 231 slides along the synchronous slide groove 232, which achieves the purpose of limitation. The synchronous bracket 231 can pull the extrusion plate 132 equipped with the first mold 133 to move, so that the first mold 133 and the second mold 134 are separated, thereby achieving the purpose of mold separation.
[0047] Embodiment 3:
[0048] The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a flat plate 31 is installed on the top of the support arm 3, the flat plate 31 and the storage box 311 are connected to each other, a transmission hose 322 is installed inside the storage box 311, the transmission hose 322 movably passes through the flat plate 31, and the output end of the transmission hose 322 is connected to the transmission cover 32. The flat plate 31 serves the purpose of support, and the length of the transmission hose 322 can be extended and the direction can be changed, which can ensure that the transmission cover 32 falls and swings smoothly.
[0049] like Figures 1 to 9 As shown, in a specific embodiment, a connecting block 41 is installed on the top of the transmission cover 32, the connecting block 41 and the positioning shaft 4 are connected to each other, a positioning slider 421 is rotatably installed on the positioning shaft 4, the positioning slider 421 is slidably set inside the positioning slide groove 42, and the positioning slide groove 42 is vertically opened on the side wall of the support arm 3, the side wall of the positioning slider 421 and the vertical rod 422 are connected to each other, and a limit seat 423 is movably inserted into the side wall of the vertical rod 422, and the limit seat 423 is welded to the side wall of the workbench 1. When the transposition roller 2 continues to rotate, the position of the notch 425 at the bottom of the transposition roller 2 changes, and the outer edge of the notch 425 can push the extrusion rod 424 to move downward, and the extrusion rod 424 drives the vertical rod 422 to slide downward along the limit seat 423, and the vertical rod 422 pulls the positioning slider 421 to slide on the positioning slide groove 42, and the positioning slider 421 slides and pulls the positioning shaft 4 to move downward as a whole, and the positioning shaft 4 drives the entire connecting block 41 and the transmission cover 32 downward, and the transmission cover 32 moves in the gap between the first mold 133 and the second mold 134, and the nozzle 321 is aligned with the mold core of the first mold 133 and the second mold 134, and the release agent is input through the pump body inside the storage box 311, so that the release agent is sprayed outward, thereby achieving the purpose of applying the release agent.
[0050] like Figures 1 to 9 As shown, further, a reset rod 43 is installed at the bottom of the positioning slider 421, the reset rod 43 is placed inside the positioning slot 42, and the reset rod 43 is movably inserted in the internal chamber of the support arm 3, a baffle 431 is installed at the end of the reset rod 43, and the baffle 431 is slidably set in the internal chamber of the support arm 3, and a reset spring 432 is clamped between the internal chamber of the support arm 3 and the baffle 431, and the compression direction of the reset spring 432 and the moving direction of the reset rod 43 are on the same straight line. When the positioning slider 421 slides downward, the reset rod 43 at the bottom of the positioning slider 421 moves downward, and the baffle 431 at the bottom of the reset rod 43 slides in the cavity, which can squeeze the reset spring 432 as a whole, and facilitate the later reset through the reset spring 432.
[0051] The implementation principle of the aluminum die-casting mold for a multi-faceted thin-walled deep-cavity workpiece of this embodiment is as follows:
[0052] When it is necessary to manufacture a multi-sided thin-walled deep-cavity workpiece, the operator needs to move the two extrusion plates 132 closer to each other, fit the first mold 133 and the second mold 134 on the extrusion plate 132 together, and pour the molten aluminum into the injection tube 14 through the input bucket 141. The poured molten aluminum flows into the cavity between the first mold 133 and the second mold 134 through the injection tube 14. Then the hydraulic push rod 142 is started, and the extrusion piston 143 is pushed to slide by the hydraulic push rod 142, so that the molten aluminum inside the injection tube 14 is completely squeezed into the internal cavity, and a cooling operation is performed. After cooling, the required multi-sided thin-walled deep-cavity workpiece can be obtained.
[0053] Then the operator needs to perform demoulding operation so that the multi-sided thin-walled deep-cavity workpiece can be taken out of the mold.
[0054] During the demoulding operation, the operator first starts the driving motor 211, and drives the transposition roller 2 to reverse through the driving motor 211 (the forward rotation of the transposition roller 2 drives the mold to approach, and the reverse rotation drives the mold to separate). At this time, the transposition roller 2 rotates synchronously on the bearing seat 21, and then the position of the combined groove 22 on the transposition roller 2 changes, and the spiral extrusion groove 222 on the transposition roller 2 drives the entire guide slider 23 to move outward, and the guide slider 23 slides along the limit rod 233, and compresses the extrusion spring 234 during sliding, and the extrusion spring 234 is used to facilitate the subsequent reset operation. When the guide slider 23 slides, it can drive the synchronous bracket 231 to move outward, and the synchronous bracket 231 slides along the synchronous slide groove 232, which achieves the purpose of limitation. The synchronous bracket 231 can pull the extrusion plate 132 installed with the first mold 133 to move, so that the first mold 133 and the second mold 134 are separated, thereby achieving the purpose of mold separation.
[0055] When the extrusion plate 132 and the first mold 133 move to a certain extent, the synchronization rod 154 and the top block 121 on the side walls of the first mold 133 and the extrusion plate 132 are squeezed and contacted with each other, and then the synchronization rod 154 can move in the opposite direction, and the synchronization rod 154 pushes the synchronization plate 151 to slide, and the synchronization plate 151 pushes the four top rods 15 to slide outward, thereby ejecting the internal workpiece to achieve the purpose of demolding, and during the sliding of the synchronization plate 151, the positioning spring 153 can be squeezed, and the subsequent resetting is facilitated by the positioning spring 153.
[0056] After being fully ejected, and the synchronous bracket 231 and the guide slider 23 slide onto the discharge chute 221, when the transposition roller continues to rotate, the position of the synchronous bracket 231 does not change, and will not continue to push the extrusion plate 132 to move, and the two molds are in a relatively static state.
[0057] When the transposition roller 2 continues to rotate, the position of the notch 425 at the bottom of the transposition roller 2 changes, and the outer edge of the notch 425 can push the extrusion rod 424 to move downward, and the extrusion rod 424 drives the vertical rod 422 to slide downward along the limit seat 423, and the vertical rod 422 pulls the positioning slider 421 to slide on the positioning slide groove 42, and the positioning slider 421 slides and pulls the positioning shaft 4 to move downward as a whole, and the positioning shaft 4 drives the entire connecting block 41 and the transmission cover 32 downward, and the transmission cover 32 moves in the gap between the first mold 133 and the second mold 134, and the nozzle 321 is aligned with the mold core of the first mold 133 and the second mold 134, and the release agent is input through the pump body inside the storage box 311, so that the release agent is sprayed outward, thereby achieving the purpose of applying the release agent.
[0058] When the positioning shaft 4 slides downward, the rocker arm 411 and the guide block 412 on the positioning shaft 4 slide on the wavy guide rail 413, and then the rocker arm 411 will be deflected, and the positioning shaft 4 will swing synchronously, and then the position of the nozzle 321 will swing at this time, ensuring that the release agent sprayed by the nozzle 321 can be more evenly attached to the mold core.
[0059] When the positioning slider 421 slides downward, the reset rod 43 at the bottom of the positioning slider 421 moves downward, and the baffle 431 at the bottom of the reset rod 43 slides in the cavity, which can squeeze the reset spring 432 as a whole, and facilitate the later reset through the reset spring 432.
