Description

Technical Field

[0001] The invention relates to the technical field of die-casting equipment, and in particular to a refrigerator panel die-casting equipment. Background Art

[0002] In the production process of refrigerators, the panels needed to manufacture refrigerator products are often die-cast by cold chamber die-casting machines to save costs. Die-casting is a metal casting process, which is characterized by using the inner cavity of the mold to apply high pressure to the molten metal, thereby making the molded product have strong tensile strength.

[0003] According to publication number CN113547094A, publication (announcement) date: 2021.10.26, a die-casting molding equipment for intelligent manufacturing is disclosed, wherein a static mold seat is fixedly installed at one end of the top of the base, a dynamic mold seat is movably installed at one end of the top of the base away from the static mold seat, an injector is fixedly installed at one end of the middle part of the static mold seat, a mold cavity is opened in the middle part of the static mold seat, a smelting furnace is fixedly installed at one end of the base, a support frame is fixedly installed on one side of the middle part of the base, and a spray cooling mechanism is fixedly installed on the top of the support frame. The present invention places the die-casting workpiece on a conveyor belt, and the rotating shaft and the conveyor belt will transport the workpiece backward when the rotating shaft and the conveyor belt rotate. During the transportation process, the water in the water tank is sprayed on the surface of the workpiece by a spray head to spray the water in the water tank on the surface of the workpiece to cool the workpiece to avoid the workpiece temperature being too high so that the staff cannot perform subsequent processing on it, and spraying with water can shorten its cooling time and improve the cooling efficiency. Impurities and dust that may adhere to its surface will also be washed away when spraying water.

[0004] In the prior art including the above-mentioned patents, the movable mold seat is used to approach the static mold seat to achieve the clamping of the movable mold and the fixed mold. However, since the movable mold seat is driven by a hydraulic cylinder to move close to the static mold seat to achieve the clamping, the clamping pressure between the movable mold seat and the static mold seat is also controlled by the hydraulic cylinder. During the die-casting process, when the movable mold and the fixed mold are close but the parting surfaces are not yet completely fitted, the feeding device injects molten metal into the fixed mold. This process is the injection step. Subsequently, the parting surfaces of the movable mold and the fixed mold are completely fitted, and high-pressure cooling and solidification of the molten metal are started to obtain a die-cast product. However, during the injection step, a clamping force is required between the movable mold seat and the static mold seat, but the parting surfaces of the movable mold and the fixed mold cannot be completely fitted to facilitate the exhaust of the mold cavity in the liquid feeding step. Therefore, it is difficult to finely control the clamping force between the movable mold and the fixed mold during the injection step by only relying on the hydraulic cylinder to apply a driving force to the movable mold seat, which easily leads to the problem of difficulty in exhausting the movable mold and the fixed mold due to unstable clamping force or a large amount of overflow during the injection process.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0035] like Figure 1-11 As shown, a refrigerator panel die-casting molding equipment includes a fixed mold base 1 and a movable mold base 2 that moves horizontally relative to the fixed mold base 2, a limit ear 21 is symmetrically arranged on the movable mold base 2, a pressurizing assembly 3 is symmetrically arranged on the fixed mold base 1, and the pressurizing assembly 3 includes a swing seat 31, an adjustment seat 32, a sliding seat 33 and a first elastic member 34, the swing seat 31 is provided with a pressurizing end 311 and a contact end 312, the sliding seat 33 is slidably arranged on the swing seat 31, the adjustment seat 32 is slidably arranged in the sliding groove 13 of the fixed mold base 1 to move relative to the swing seat 31, the two ends of the first elastic member 34 are respectively fixedly connected to the adjustment seat 32 and the sliding seat 33 to be inclined, and the swing seat 31 is movably assembled on the fixed mold base 1 to have the following two stations:

[0036] In the first station, the first elastic member 34 pulls the sliding seat 33 to slide so as to pull the pressurizing end 311 of the swing seat 31 to rotate away from the movable die seat 2, and the contact end 312 extends obliquely to between the fixed die seat 1 and the movable die seat 2;

[0037] In the second station, the movable mold base 2 pushes the contact end 312 to drive the swing base 31 to rotate close to the movable mold base 2, and the pressurizing end 311 of the swing base 31 rotates to contact the contact groove 211 of the limiting ear 21, and the first elastic member 34 pulls the swing base 31 to slide horizontally to apply mold clamping pressure to the movable mold base 2.

[0038] Specifically, Fig.12 As shown, it also includes a bed 95, the fixed mold base 1 and the movable mold base 2 are arranged in the bed 95, and a movable door 951 is also arranged on the bed 95 to cover the fixed mold base 1 and the movable mold base 2, as shown in FIG. Figure 2 As shown, the fixed die seat 1 and the movable die seat 2 are respectively provided with a lower die groove 16 and an upper die cavity 22, and also include a driving cylinder 91 for driving the movable die seat 2 to move closer to the fixed die seat 1, and the swing seat 31 of the pressurizing assembly 3 is movably arranged on the fixed die seat 1, the sliding seat 33 is slidably arranged on the swing seat 31, and the adjusting seat 32 is slidably arranged on the fixed die seat 1, and the two ends of the first elastic member 34 are respectively connected to the adjusting seat 32 and the sliding seat 33 so that the first elastic member 34 is inclined. When the movable die seat 2 is away from the fixed die seat 1 and the die casting operation has not yet been performed, as shown in FIG. Figure 2As shown, the first elastic member 34 is arranged at an angle so that the first elastic member 34 can pull the sliding seat 33 to drive the swing seat 31 to swing and remain in the first position. At this time, the pressurizing end 311 of the swing seat 31 is located on the side away from the movable mold seat 2, and the contact end 312 rotates to a position extending in an inclined shape between the fixed mold seat 1 and the movable mold seat 2. At this time, the swing seat 31 is in the die-casting preparation stage. Subsequently, when the die-casting operation is required, the driving cylinder 91 drives the movable die seat 2 to move close to the fixed die seat 1. While the movable die seat 2 moves close to the fixed die seat 1, it also pushes the contact end 312 of the swing seat 31, thereby causing the swing seat 31 to stretch the first elastic member 34 and rotate close to the movable die seat 2 until the movable die seat 2 moves close to the fixed die seat 1. However, when the parting surfaces of the movable die seat 2 and the fixed die seat 1 are not completely fitted together, the swing seat 31 is pushed by the movable die seat 2 and rotates to the second station. At this time, the pressurizing end 311 of the swing seat 31 has rotated to contact the contact groove 211 provided on the limiting ear 21 of the movable die seat 2, and at this time, as shown in FIG. Figure 2 As shown, due to the swinging of the swing seat 31, the first elastic member 34 pulls the sliding seat 33 to slide to the end of its stroke closest to the fixed mold seat 1, so the first elastic member 34 can apply pressure toward the fixed mold seat 1 to the swing seat 31 through the sliding seat 33, and the first elastic member 34 pulls the swing seat 31 to slide horizontally close to the fixed mold seat 1 so that the pressurizing end 311 contacts the limiting ear 21 and applies a clamping pressure to the movable mold seat 2 to move closer to the fixed mold seat 1, and the first elastic member 34 is used to symmetrically apply additional clamping pressure to the circumference of the movable mold seat 2 through the swing seat 31, thereby improving the stability of the movable mold seat 2 and the fixed mold seat 1 during mold closing injection, and the symmetrically arranged swing seat 31 can balance the clamping pressure on the circumference of the movable mold seat 2, thereby avoiding liquid leakage caused by the small circumferential pressure of the movable mold seat 2 during the injection step.

[0039] Secondly, if Figure 2 As shown, the adjustment seat 32 is slidably disposed on the fixed mold seat 1, and the adjustment seat 32 slides relative to the swing seat 31. Therefore, the adjustment seat 32 can be slidably located on the fixed mold seat 1 to move relative to the swing seat 31, thereby changing the elastic force of the first elastic member 34 to finely adjust the clamping pressure of the swing seat 31 and the movable mold seat 2 and the fixed mold seat 1, so as to achieve more precise clamping pressure control in the die-casting injection steps for different materials, and avoid the problem of difficult exhaust or large amount of overflow caused by unstable clamping force of the movable mold and the fixed mold during the injection process.

[0040] Furthermore, the swing seat 31 is provided with a rotating part 313, and the rotating part 313 is provided with an elliptical wheel part 3131. The rotating part 313 is movably arranged in the horizontal shift groove 111 opened on the fixed mold seat 1. The fixed mold seat 1 is provided with an active cavity 12 and an insertion cavity 121 horizontally connected to the active cavity 12. The elliptical wheel part 3131 is movably arranged in the active cavity 12, and the groove width of the insertion cavity 121 is equal to the shortest diameter of the elliptical wheel part 3131. The swing seat 31 is located at the second station so that the shortest diameter position of the elliptical wheel part 3131 is aligned with the insertion cavity 121. Fig. 9 As shown, the elliptical wheel portion 3131 is movably arranged in the movable cavity 12, and because the shortest diameter of the elliptical wheel portion 3131 is equal to the slot width of the inserted cavity 121, when the movable die seat 2 is not close to the fixed die seat 1 in the preparation stage of the die casting operation, the swing seat 31 is located at the first station, at which time the shortest diameter position of the elliptical wheel portion 3131 on the swing seat 31 is not aligned with the inserted cavity 121, so the swing seat 31 can only swing and rotate, and when the movable die seat 2 moves close to the fixed die seat 1 to push the swing seat 31 to switch from the first station to the second station, the elliptical wheel portion 3131 is at the first station. The shortest diameter position of 131 is aligned with the insertion cavity 121. At this time, the first elastic member 34 can pull the swing seat 31 to make the elliptical wheel portion 3131 slide horizontally into the insertion cavity 121, so that the swing seat 31 can be horizontally moved closer to the fixed mold seat 1 when it is located at the second station, so that the swing seat 31 is pulled by the first elastic member 34 to apply the clamping pressure to the movable mold seat 2, thereby improving the pressure stability of the swing seat 31 on the movable mold seat 2, and further avoiding the problem of difficulty in venting or a large amount of overflow caused by unstable clamping force between the movable mold and the fixed mold during the injection process.

[0041] In the above technical scheme, the swing seat 31 can be used to switch from the first station to the second station to snap onto the limiting ear 21 of the movable mold seat 2, and the first elastic member 34 can be used to symmetrically apply additional clamping pressure to the circumference of the movable mold seat 2 through the swing seat 31, thereby improving the stability of the movable mold seat 2 and the fixed mold seat 1 during mold clamping and injection, and the symmetrically arranged swing seat 31 can balance the clamping pressure on the circumference of the movable mold seat 2, avoiding the leakage of the movable mold seat 2 caused by the small circumferential pressure in the injection step. Secondly, the adjustment seat 32 can be located on the fixed mold seat 1 and slide to move relative to the swing seat 31, thereby changing the elastic force of the first elastic member 34 to finely adjust the clamping pressure of the swing seat 31, the movable mold seat 2 and the fixed mold seat 1, so as to facilitate more precise clamping pressure control in the die-casting injection step for different materials, and avoid the problem of venting difficulty or a large amount of overflow caused by unstable clamping force of the movable mold and the fixed mold during the injection process.

[0042] As another embodiment provided by the present invention, a limit plate 41 is movably provided on the swing seat 31, and a contact slope 212 is provided on the limit ear 21. When the swing seat 31 is driven to rotate from the first station to the second station, the limit plate 41 follows the swing seat 31 and approaches the limit ear 21, and the end of the limit plate 41 contacts the contact slope 212 so that the limit plate 41 is pressed and moves along the plate surface of the swing seat 31 while symmetrically extruding the movable mold seat 2.

[0043] Specifically, Figure 2 As shown, the limit plate 41 is movably arranged on the swing seat 31, and the end of the limit plate 41 facing away from the swing seat 31 is in an arc shape, and the limit ear 21 is provided with a resistance slope 212. When the die casting operation is required, the driving cylinder 91 drives the movable die seat 2 to move close to the fixed die seat 1. While moving close to the fixed die seat 1, the movable die seat 2 will also push the swing seat 31 to rotate from the first station to the second station, and the limit plate 41 follows the swing seat 31 to rotate synchronously close to the limit ear 21 of the movable die seat 2. At this time, the arc-shaped end of the symmetrically arranged limit plate 41 resists against the resistance slope 212 of the limit ear 21 and slides to apply a symmetrical thrust to the movable die seat 2, so that the limit plate 41 on the swing seat 31 is used to provide lateral stabilizing force to the movable die seat 2 in the sliding stroke, thereby reducing the lateral swing of the movable die seat 2 during the movement process, thereby improving the mold alignment between the movable die seat 2 and the fixed die seat 1, and improving the quality of die casting.

[0044] As another embodiment provided by the present invention, it also includes a mounting seat 5 slidably set on the limit plate 41. When the swing seat 31 is driven to switch from the first station to the second station, the swing seat 31, the fixed mold seat 1 and the movable mold seat 2 are combined to form a heat preservation chamber. A partition plate 51 is provided on the mounting seat 5 for separating the heat preservation chamber to form an air pressure chamber 94. The air pressure chamber 94 is connected to the parting surface between the fixed mold seat 1 and the movable mold seat 2. The mounting seat 5 moves along the plate surface of the swing seat 31 following the limit plate 41 to enable the partition plate 51 to move to increase the volume of the air pressure chamber 94.

[0045] Specifically, Figure 7 As shown, the mounting seat 5 is slidably disposed on the limit plate 41, and when the movable mold seat 2 is driven to move close to the fixed mold seat 1 and drive the swing seat 31 to rotate from the first station to the second station, the movable mold seat 2 and the fixed mold seat 1 are close to each other but not completely fitted together, and the swing seat 31 rotates close to the movable mold seat 2 so that the swing seat 31, the movable mold seat 2 and the fixed mold seat 1 are surrounded to form an insulation chamber, and the insulation chamber is located outside the mold closing position of the movable mold seat 2 and the fixed mold seat 1, and then the insulation chamber is used to perform insulation treatment on the outer parts of the movable mold seat 2 and the fixed mold seat 1, so as to avoid the problem of internal cracking or deformation caused by the large temperature difference between the inside and outside of the movable mold seat 2 and the fixed mold seat 1, thereby further improving the quality of the die-casting products.

[0046] Secondly, since the mounting seat 5 is provided with a partition plate 51, when the swing seat 31, the movable die seat 2 and the fixed die seat 1 are combined to form a heat preservation chamber, the two ends of the partition plate 51 respectively contact the movable die seat 2 and the swing seat 31 to separate the heat preservation chamber to form an air pressure chamber 94, and the parting surface between the air pressure chamber 94 and the fixed die seat 1 and the movable die seat 2 is provided with an exhaust groove required in the die casting injection step at the parting surface, so the air pressure chamber 94 is connected with the exhaust groove inside the movable die seat 2 and the fixed die seat 1, and since the swing seat 31 is in the process of rotating and switching to the second station, the arc-shaped end of the limit plate 41 contacts the contact slope 212 of the limit ear 21 to slide to apply a symmetrical thrust to the movable die seat 2, and at this time, the mounting The seat 5 slides horizontally away from the fixed mold seat 1 following the sliding of the limit plate 41, so that the piston in the partition plate 51 located in the heat preservation chamber slides away from the fixed mold seat 1 to increase the partition volume of the air pressure chamber 94. At this time, the partition volume in the air pressure chamber 94 increases and the air pressure in the air pressure chamber 94 decreases, so that when the injection step is performed, the feeding equipment injects molten metal into the fixed mold seat 1, and the mold cavity is injected with molten metal at high pressure, so that the air in the mold cavity is squeezed out into the air pressure chamber 94 along the exhaust groove, and the mounting seat 5 and the partition plate 51 are used to make the air pressure chamber 94 in a low pressure state, so that the feeding and injection in the mold cavity can be smoother, the mold exhaust performance in the injection step is improved, and the problem of residual gas in the mold cavity is reduced.

[0047] Among them, a rubber sealing strip can be additionally provided on the side of the swing seat 31 facing the movable mold seat 2. When the swing seat 31 is located at the second workstation and is surrounded by the movable mold seat 2 and the fixed mold seat 1 to form an insulation chamber, the rubber sealing strip contacts the movable mold seat 2 and the fixed mold seat 1 to increase the sealing of the insulation chamber and improve the insulation performance of the swing seat 31.

[0048] As another embodiment provided by the present invention, a limiting seat 61, a driving plate 62, a horizontal slide 42 and a second elastic member 43 are arranged in the swing seat 31. The limiting seat 61, the driving plate 62 and the horizontal slide 42 are all slidably arranged, and the horizontal slide 42 is slidably assembled with the limiting plate 41. The limiting seat 61 is in a default state so that the supporting portion 611 thereon abuts against the first end of the limiting plate 41 to lock the vertical movement of the limiting plate 41. When the swing seat 31 is located in the second station and is pulled by the first elastic member 34 to slide horizontally, the driving plate 62 slides to drive the limiting seat 61 to slide away from the limiting plate 41 to vertically unlock the limiting plate 41. The limiting plate 41 is driven by the second elastic member 43 and the horizontal slide 42 to move toward the fixed mold seat 1 along the abutment slope 212, and the partition plate 51 moves horizontally following the horizontal movement of the limiting plate 41 to reduce the volume of the air pressure chamber 94.

[0049] Specifically, Figure 7As shown, a limited seat 61 and a driving plate 62 are slidably arranged in the swing seat 31, and the driving plate 62 is slidably arranged in an open slide groove 314 opened in the swing seat 31, and a push portion 14 is arranged on the fixed mold seat 1, as shown in FIG. Figure 7 As shown, the end of the limit plate 41 facing away from the movable mold seat 2 is the first end, and the limit seat 61 is in a default state so that the abutting portion 611 on the limit seat 61 abuts against the first end of the limit plate 41, thereby realizing that when the swing seat 31 is in the second position, the movement of the limit plate 41 perpendicular to the movement direction of the movable mold seat 2 is locked, and the arc-shaped end of the limit plate 41 abuts against the abutting slope 212 of the limit ear 21 to realize the movement locking of the limit plate 41 parallel to the movement direction of the movable mold seat 2, and when the swing seat 31 is in the second position, the swing seat 31 is in the second position. The movable seat 31 has rotated until the open end of the open chute 314 is aligned and parallel to the push portion 14. If the first elastic member 34 can apply pressure toward the fixed mold seat 1 to the swing seat 31 through the sliding seat 33 at this time, the first elastic member 34 pulls the swing seat 31 to slide horizontally from the second station to the fixed mold seat 1 to apply mold clamping pressure. When the feeding device completes the injection step in the mold cavity, the swing seat 31 slides horizontally so that the push portion 14 extends into the open chute 314 to push the driving plate 62 to slide, and the driving plate 62 slides to push the limit seat 61 The limit plate 41 slides away from the default state, and the limit seat 61 no longer limits the movement of the limit plate 41 perpendicular to the movement direction of the movable die seat 2. At this time, the movable die seat 2 and the parting surface of the fixed die seat 1 are completely fitted to perform die casting, that is, the high pressure solidification in the mold cavity between the movable die seat 2 and the fixed die seat 1 forms a die-casting product, and the second elastic member 43 pulls the horizontal slide seat 42 to slide horizontally toward the fixed die seat 1, and the limit plate 41 follows the horizontal slide seat 42 and slides toward the fixed die seat 1 along the abutment slope 212, so the stop plate 41 is installed The mounting seat 5 is pushed by the movement of the limiting plate 41 and slides closer to the fixed die seat 1, so that after the injection step of the die casting is completed, the partition plate 51 of the mounting seat 5 moves closer to the piston of the fixed die seat 1 to reduce the volume of the air pressure chamber 94, so that the air pressure chamber 94 is in a high pressure state. The air pressure chamber 94 applies pressure to the parting surface gap between the movable die seat 2 and the fixed die seat 1 to reduce the additional overflow of the molten metal in the mold cavity during the die casting solidification process, thereby improving the utilization rate of the molten metal raw material and improving the molding quality of the molded product.

[0050] Further, such as Figure 7As shown, an inclined slot 612 is provided in the limit seat 61, and a sliding column portion 621 is provided at the end of the driving plate 62. The sliding column portion 621 is slidably provided in the inclined slot 612. When the driving plate 62 is pushed and slides by the pushing portion 14, the sliding column portion 621 is located in the inclined slot 612 and slides to push the limit seat 61 to slide away from the limit plate 41, and then the inclined slot 612 and the sliding column portion 621 are used to realize the driving of the limit seat 61 by the driving plate 62, thereby improving the transmission stability. Secondly, a third elastic member 63 for driving the limit seat 61 to reset to a default state is also provided in the swing seat 31, so that when the die-casting operation is completed, the third elastic member 63 can push the limit seat 61 and the driving plate 62 to reset for the next drive.

[0051] The second elastic member 43 and the third elastic member 63 can be replaced by springs, elastic plates, air bags and other elastic materials known to those skilled in the art.

[0052] As another embodiment provided by the present invention, a sealing member 92 and a fourth elastic member 93 are provided on the mounting seat 5, a connecting hole 52 connected to the air pressure chamber 94 is provided on the partition plate 51, and an ejection hole 53 inclined toward the pressurizing end 311 is provided on the mounting seat 5, the ejection hole 53 and the connecting hole 52 are connected, and the fourth elastic member 93 pushes the sealing member 92 to slide and maintain a default state to separate the connecting hole 52 and the ejection hole 53. When the movable mold seat 2 is driven away from the fixed mold seat 1 to allow the swing seat 31 to slide horizontally into the second workstation, the limit seat 61 slides and resets to the default state to push and move along the contact slope 212 back to the fixed mold seat 1, and the limit plate 41 slides vertically to drive the sealing member 92 to slide by friction to connect the connecting hole 52 and the ejection hole 53.

[0053] Specifically, Figure 6 As shown, the horizontal slide seat 42 is provided with a sliding portion 421, and the limiting plate 41 is provided with a vertical sliding groove 411, and the sliding portion 421 is slidably arranged in the vertical sliding groove 411, as shown in FIG. Figure 7As shown, the mounting seat 5 and the partition plate 51 are provided with a connecting hole 52 and an ejection hole 53 which are connected to each other, and the blocking member 92 is elastically driven by the fourth elastic member 93 to remain in a default state to separate the connecting hole 52 and the ejection hole 53. When the movable mold seat 2 moves toward the fixed mold seat 1 to perform the injection step, during the process of the swing seat 31 rotating from the first station to the second station, the arc-shaped end of the limit plate 41 slides against the contact slope 212 of the limit ear 21, and at this time, the mounting seat 5 slides along with the limit plate 41. The movable mold base 2 moves and slides horizontally away from the fixed mold base 1. At this time, the limit plate 41 is restricted by the limit seat 61 and cannot move perpendicular to the movement direction of the movable mold base 2. Therefore, the limit plate 41 and the mounting seat 5 are relatively still, so that the blocking member 92 is still pushed by the fourth elastic member 93 to separate the connecting hole 52 and the ejection hole 53, thereby avoiding the air leakage problem in the air pressure chamber 94 caused by the movement of the partition plate 51 to increase the separation volume of the air pressure chamber 94. The airtightness of the air pressure chamber 94 facilitates the exhaust of the mold cavity in the injection step.

[0054] When the injection step of the mold cavity is completed, the driving plate 62 slides to push the limit seat 61 to slide away from the limit plate 41 from the default state, and the limit plate 41 can move perpendicular to the movement direction of the movable mold seat 2. At this time, the movable mold seat 2 and the parting surface of the fixed mold seat 1 are completely fitted for die-casting, that is, the high pressure in the mold cavity between the movable mold seat 2 and the fixed mold seat 1 solidifies to form a die-cast product, and the second elastic member 43 pulls the horizontal slide seat 42 to slide horizontally toward the fixed mold seat 1, and the limit plate 41 follows the horizontal slide seat 42 and slides toward the fixed mold seat 1 along the contact slope 212. Therefore, the mounting seat 5 on the limit plate 41 is pushed by the movement of the limit plate 41 and slides toward the fixed mold seat 1. The position plate 41 slides relative to the mounting seat 5 along the direction of the fourth elastic member 93 toward the blocking member 92, so that the friction force generated between the position limit plate 41 and the blocking member 92 can drive the position limit plate 41 to drive the blocking member 92 to further move back to the fourth elastic member 93, thereby further improving the separation and sealing between the ejection hole 53 and the connecting hole 52, and improving the airtightness of the air pressure chamber 94 when the partition plate 51 moves to make the air pressure chamber 94 in a high pressure state, avoiding air leakage in the air pressure chamber 94, and facilitating the air pressure chamber 94 to apply pressure to the parting surface gap between the movable mold seat 2 and the fixed mold seat 1 to reduce the additional overflow of the molten metal in the mold cavity during the die casting solidification process.

[0055] When the die casting is completed, the movable die seat 2 is driven away from the fixed die seat 1, and the movable die seat 2 first drives the swing seat 31 to slide horizontally and return to the second station. At this time, the push portion 14 leaves the open slide groove 314, and the third elastic member 63 can push the limit seat 61 and the driving plate 62 to return to their original position. The limit seat 61 is reset to the default state so that the support portion 611 faces the first end of the push limit plate 41. At this time, the limit plate 41 is pressed and slides away from the fixed die seat 1 along the contact slope 212. The limit plate 41 symmetrically presses the contact slope 212 to improve the stability of the movable die seat 2 when it moves away from the fixed die seat 1, reduce the damage to the molded workpiece caused by the jitter during the demoulding process, and improve the molding quality of the product. Secondly, in the process of sliding the limit plate 41 away from the fixed die seat 1, the installation The seat 5 follows the sliding of the limit plate 41 and synchronously moves away from the fixed mold seat 1, and the limit plate 41 slides along the sealing member 92 toward the fourth elastic member 93 relative to the mounting seat 5, so that the limit plate 41 pushes the sealing member 92 through friction to compress the fourth elastic member 93 to slide so as to achieve the connection between the connecting hole 52 and the ejection hole 53. At this time, the air pressure chamber 94 is in a high pressure state, so that the gas in the air pressure chamber 94 is ejected along the connecting hole 52 and the ejection hole 53 toward the pressurized end 311 of the swing seat 31, thereby achieving cooling and cleaning of the pressurized end 311, avoiding the high-temperature bonding phenomenon between the pressurized end 311 and the limit ear 21, and causing the swing seat 31 and the movable mold seat 2 to adhere, thereby improving the separation stability of the swing seat 31. As the movable mold base 2 moves away from the fixed mold base 1 , the pressure of the movable mold base 2 on the contact end 312 of the swing base 31 gradually decreases, and the swing base 31 gradually rotates from the second position to the first position under the pulling force of the first elastic member 34 to move away from the movable mold base 2 .

[0056] The fourth elastic member 93 can be replaced by any elastic object known to those skilled in the art, such as a spring, an elastic plate or an airbag.

[0057] As another embodiment provided by the present invention, the first end of the partition plate 51 is provided with a flexible contact plate 7 which is arc-shaped and protrudes in a default state. When the swing seat 31 is driven to switch from the first station to the second station, the partition plate 51 rotates close to the movable mold seat 2 to make the flexible contact plate 7 deform and contact the movable mold seat 2. A connecting channel 54 is opened in the partition plate 51 and is located on the inner side of the flexible contact plate 7 and is connected to the connecting hole 52.

[0058] Specifically, Figure 7As shown, the end of the partition plate 51 facing away from the swing seat 31 is the first end, and a flexible contact plate 7 is arranged on it. When the swing seat 31 is located in the first station so as not to contact the movable mold seat 2, the flexible contact plate 7 is arc-shaped and protrudes. When the swing seat 31 rotates from the first station to the second station to form a heat-insulating chamber together with the movable mold seat 2 and the fixed mold seat 1, the partition plate 51 rotates with the swing seat 31 so that the flexible contact plate 7 is pressed against the side of the movable mold seat 2 to deform so as to improve the airtightness between the partition plate 51 and the movable mold seat 2, thereby further improving the heat preservation and airtightness of the heat-insulating chamber formed by the swing seat 31, the movable mold seat 2 and the fixed mold seat 1, and improving the protection of the movable mold seat 2 and the fixed mold seat 1.

[0059] Secondly, the connecting channel 54 is connected to the connecting hole 52, and the other end of the connecting channel 54 is located on the inner side of the flexible contact plate 7. When the air pressure chamber 94 is in a high pressure state, the air pressure can cause the flexible contact plate 7 to deform and fit tightly to the surface of the movable mold base 2 to further provide air tightness for the air pressure chamber 94.

[0060] As another embodiment provided by the present invention, a sliding plate 81 is slidably arranged on the swing seat 31, and a flexible protruding plate 82 is arranged on the sliding plate 81. In the default state, the sliding plate 81 makes the flexible protruding plate 82 tilted along the direction of the contact end 312 and protruded to between the fixed mold seat 1 and the movable mold seat 2. When the swing seat 31 is driven to rotate from the first station to the second station, the sliding plate 81 is driven to make the flexible protruding plate 82 slide back into the contact end 312, and the flexible protruding plate 82 is located at the first side of the contact end 312 close to the fixed mold seat 1.

[0061] Specifically, Fig. 9 As shown, a sliding plate 81 is provided on the contact end 312 of the swing seat 31 to slide parallel to the contact end 312, and a flexible extension plate 82 is provided on the sliding plate 81. When the swing seat 31 is located at the first station, the sliding plate 81 is in a default state so that the flexible extension plate 82 on the sliding plate 81 is tilted and extended along the direction of the contact end 312 to between the fixed mold seat 1 and the movable mold seat 2. When the movable mold seat 2 moves close to the fixed mold seat 1 to perform the injection step, the movable mold seat 2 first contacts the flexible extension plate 82 to resist The swing seat 31 is pushed to rotate from the first station to the second station, and as the swing seat 31 continues to rotate, the sliding plate 81 is driven to slide so that the flexible extension plate 82 gradually slides back to the inner side of the contact end 312, so that the movable mold seat 2 gradually contacts the contact end 312 due to the retraction of the flexible extension plate 82, thereby reducing the impact force of the movable mold seat 2 when contacting and pushing the contact end 312, achieving buffer protection for the movable mold seat 2 and the swing seat 31, and improving the service life of the swing seat 31 and the movable mold seat 2;

[0062] When the movable mold base 2 and the fixed mold base 1 fit each other and the die casting inside the mold cavity is completed, the movable mold base 2 moves away from the fixed mold base 1, and the swing seat 31 is driven by the first elastic member 34 to rotate and switch from the second station to the first station. At this time, the sliding plate 81 is driven to slide so that the flexible extension plate 82 gradually extends between the movable mold base 2 and the fixed mold base 1. Since the swing seat 31 has not yet completely separated from the movable mold base 2, when the flexible extension plate 82 gradually extends out of the contact end 312, the flexible extension plate 82 contacts the parting surface of the movable mold base 2 and gradually extends out to scrape off the impurities or dust produced by die casting on the parting surface of the movable mold base 2, thereby cleaning the parting surface of the movable mold base 2, and then the movable mold base 2 continues to move away from the fixed mold Seat 1, until the swing seat 31 is separated from the movable mold seat 2, the first elastic member 34 pulls the swing seat 31 to accelerate its reset to the first station, and the flexible protruding plate 82 is originally in a bent shape to contact the parting surface of the movable mold seat 2. When the flexible protruding plate 82 is separated from the movable mold seat 2, the flexible protruding plate 82 is reset to the original position due to its own elastic deformation, so that the flexible protruding plate 82 will knock the flexible contact plate 7 on the first end of the partition plate 51 during the reset process. At this time, the arc-shaped protruding flexible contact plate 7 is knocked to squeeze and eject the inner gas instantly along the connecting channel 54 to the connecting hole 52, thereby realizing the reverse impact cleaning of the connecting hole 52, and the ejected gas can also jet and clean the floating dust contaminated inside the swing seat 31.

[0063] When the swing seat 31 is reset and rotated to the first working position, the flexible extension plate 82 is also extended obliquely to between the movable mold seat 2 and the fixed mold seat 1, and the flexible extension plate 82 is extended and located at the front side of the mold cavity of the fixed mold seat 1 to protect the molded product in the mold cavity, avoiding damage to the workpiece caused by direct falling of the molded workpiece when the push rod is pushed out, thereby improving the protection of the workpiece during die-casting demolding.

[0064] Furthermore, a transmission assembly 83 is provided in the swing seat 31, an extension column 15 is provided on the fixed mold seat 1, a gear ring 151 is provided on the extension column 15, the transmission assembly 83 includes a first transmission gear 831, a second transmission gear 832, a third transmission gear 833, a synchronous belt 834 and a driving gear 835, the gear ring 151 is coupled with the first transmission gear 831, the first transmission gear 831, the second transmission gear 832, and the third transmission gear 833 are coupled in sequence, the third transmission gear 833 and the driving gear 835 are kept in synchronous rotation through the synchronous belt 834, and the driving gear 835 is coupled with the tooth groove on the sliding plate 81. Fig.10As shown, an extension column portion 15 is provided on the fixed mold base 1, and a ring gear portion 151 is provided on the extension column portion 15. When the swing seat 31 is pushed by the movable mold base 2 and rotates and switches from the first station to the second station, the transmission component 83 in the swing seat 31 rotates and swings relative to the ring gear portion 151. Therefore, the first transmission gear 831, the second transmission gear 832, the third transmission gear 833, and the synchronous belt 834 drive the driving gear 835 to rotate in sequence, and the driving gear 835 rotates to drive the sliding plate 81 to slide and drive the flexible protruding plate 82 to retract into the contact end 312. The transmission component 83 is used to realize the driving of the sliding plate 81 when the swing seat 31 rotates, reducing the driving source to improve the operating stability of the device. Secondly, the existence of the transmission component 83 with a high transmission ratio can also reduce the speed of the swing seat 31 rotating and switching to the second station, and then by reducing the rotation speed of the swing seat 31, the deceleration buffer of the movable mold base 2 moving close to the fixed mold base 1 is realized, thereby improving the service life of the movable mold base 2 and the fixed mold base 1.

[0065] As another embodiment provided by the present invention, a protrusion 821 is provided at the end of the flexible protruding plate 82, and an inner groove 112 is opened in the movable groove 11 of the fixed mold seat 1. The swing seat 31 is driven to switch from the first station to the second station so that the flexible protruding plate 82 retracts to the side wall of the groove where the protrusion 821 abuts against the movable groove 11. When the swing seat 31 is located in the second station and is pulled horizontally by the first elastic member 34, the sliding plate 81 is driven to slide so that the flexible protruding plate 82 retracts to the protrusion 821 abuts against the inner groove 112.

[0066] Specifically, Fig.10 As shown, an inner groove 112 is provided in the movable groove 11 of the fixed mold base 1. When the swing seat 31 is pushed by the movable mold base 2 and rotates from the first station to the second station, the transmission assembly 83 in the swing seat 31 drives the sliding plate 81 to slide and drive the flexible protruding plate 82 to retract into the contact end 312. When the swing seat 31 is located in the second station, the flexible protruding plate 82 is driven to retract to the groove side wall where the protrusion 821 abuts against the movable groove 11, thereby making the contact end 312 higher than the parting surface of the fixed mold base 1 through the flexible protruding plate 82, so that the contact end 312 is higher than the parting surface of the fixed mold base 1 by using the contact end 312 and the flexible protruding plate 82 during the die-casting injection process. The parting surface between the movable mold base 2 and the fixed mold base 1 is always not completely fitted to facilitate the smooth exhaust during the injection process and improve the quality of the molded product.

[0067] When the injection step is completed, the swing seat 31 is located in the second station and slides horizontally pulled by the first elastic member 34. The sliding plate 81 is driven to slide so that the flexible protruding plate 82 retracts to the protrusion 821 and contacts the inner groove 112. At this time, the contact end 312 is flush with the parting of the fixed mold seat 1, and the movable mold seat 2 applies pressure to the fixed mold seat 1 on the contact end 312. The first elastic member 34 also applies pressure to the fixed mold seat 1 on the swing seat 31, so that the flexible protruding plate 82 located between the contact end 312 and the fixed mold seat 1 is compressed and deformed to fill the gap between the swing seat 31 and the fixed mold seat 1, thereby further improving the air tightness of the air pressure chamber 94 under high pressure, and improving the stability of the high pressure inside the air pressure chamber 94 to reduce the overflow of the molten metal.

[0068] Working principle: First, the swing seat 31 is located at the first station. When the movable mold seat 2 moves close to the fixed mold seat 1 to perform the injection step, the movable mold seat 2 first contacts the flexible extension plate 82 to push the swing seat 31 to rotate from the first station to the second station. As the swing seat 31 continues to rotate, the sliding plate 81 is driven to slide so that the flexible extension plate 82 gradually slides back to the inside of the contact end 312, so that the movable mold seat 2 gradually contacts the contact end 312 due to the retraction of the flexible extension plate 82, thereby reducing the impact force of the movable mold seat 2 when contacting and pushing the contact end 312;

[0069] When the swing seat 31 is rotated and switched from the first station to the second station, the arc-shaped end of the limit plate 41 slides against the contact slope 212 of the limit ear 21, and the mounting seat 5 follows the sliding of the limit plate 41 and slides horizontally away from the fixed mold seat 1. When the swing seat 31, the movable mold seat 2 and the fixed mold seat 1 form a heat preservation chamber, the two ends of the partition plate 51 respectively contact the movable mold seat 2 and the swing seat 31 to separate the heat preservation chamber to form an air pressure chamber 94, and the feeding equipment injects molten metal into the fixed mold seat 1, and the mold cavity is injected with molten metal at high pressure, so that the air in the mold cavity is squeezed out into the air pressure chamber 94 along the exhaust groove, and the mounting seat 5 and the partition plate 51 are used to make the air pressure chamber 94 in a low pressure state, so that the feeding and injection in the mold cavity can be smoother, and the mold exhaust performance in the injection step is improved;

[0070] When the injection step of the mold cavity is completed, the driving plate 62 slides to push the limit seat 61 to slide away from the limit plate 41 from the default state, and the limit plate 41 can move perpendicular to the movement direction of the movable mold seat 2. At this time, the parting surface of the movable mold seat 2 and the fixed mold seat 1 are completely fitted to perform die casting, that is, the mold cavity between the movable mold seat 2 and the fixed mold seat 1 is solidified under high pressure to form a die-casting product, and the second elastic member 43 pulls the horizontal slide seat 42 to slide horizontally toward the fixed mold seat 1, and the limit plate 41 follows the horizontal slide seat 4 2 and slides toward the fixed die seat 1 along the abutting slope 212, so the mounting seat 5 on the limiting plate 41 is pushed by the movement of the limiting plate 41 and slides toward the fixed die seat 1, and the partition plate 51 of the mounting seat 5 moves closer to the piston of the fixed die seat 1 to reduce the volume of the air pressure chamber 94, so that the air pressure chamber 94 is in a high air pressure state, and the air pressure chamber 94 applies pressure to the parting surface gap between the movable die seat 2 and the fixed die seat 1 to reduce the additional overflow of the metal liquid in the mold cavity during the die casting solidification process;

[0071] When the die casting is completed, the movable die seat 2 is driven away from the fixed die seat 1, and the movable die seat 2 first drives the swing seat 31 to slide horizontally and return to the second station. At this time, the push portion 14 leaves the open slide groove 314, and the third elastic member 63 can push the limit seat 61 and the driving plate 62 to return to the original state. The limit seat 61 is reset to the default state so that the support portion 611 faces the first end of the push limit plate 41. At this time, the limit plate 41 is pressed and slides away from the fixed die seat 1 along the contact slope 212. The limit plate 41 pushes the blocking member 92 through the friction force to compress the fourth elastic member 93 to slide so as to achieve the connection between the connecting hole 52 and the ejection hole 53. The gas in the air pressure chamber 94 is ejected along the connecting hole 52 and the ejection hole 53 to the pressurized end 311 of the swing seat 31, thereby achieving the cooling and cleaning of the pressurized end 311.

[0072] At the same time, the swing seat 31 is driven by the first elastic member 34 to rotate and switch from the second station to the first station. At this time, the sliding plate 81 is driven to slide so that the flexible extension plate 82 gradually extends between the movable mold seat 2 and the fixed mold seat 1. Since the swing seat 31 has not yet completely separated from the movable mold seat 2, when the flexible extension plate 82 gradually extends out of the contact end 312, the flexible extension plate 82 contacts the parting surface of the movable mold seat 2 and gradually extends out to scrape off the impurities or dust produced by die casting on the parting surface of the movable mold seat 2.

[0073] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
