Description

Technical Field

[0001] The utility model relates to the technical field of die-casting molds, in particular to a die-casting mold for an inverter radiator. Background Technique

[0002] An inverter is a device that converts DC electrical energy (batteries, accumulators) into AC electrical energy (usually 220V 50HZ sine or square wave). Generally speaking, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of an inverter bridge, control logic, and a filter circuit, and is widely applicable to air conditioners, home theaters, electric grinders, power tools, sewing machines, DVDs, VCDs, computers, TVs, washing machines, range hoods, refrigerators, video recorders, massagers, fans, lighting, etc. Among them, the outer shell of the inverter used in the photovoltaic industry is generally manufactured by die-casting technology, making its outer shell structure firm and having high protection performance.

[0003] The existing radiator structure on the inverter is relatively complex. Therefore, multiple core-pulling structures are added to the inner cavity of the mold from multiple directions (such as the Chinese utility model with the application number CN202322484170.9) for splicing or demolding in multiple directions, resulting in good mold opening effect. However, currently, the core-pulling structure on the die-casting mold generally directly connects a set of hydraulic cylinders to perform the pulling / pushing work on it. This leads to the installation of multiple hydraulic cylinders outside the device using multiple core-pulling structures. The setting of multiple sets of hydraulic cylinders not only occupies the space of the production workshop but also increases the production cost of the workpiece. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the disadvantages that the core-pulling structure on the existing die-casting mold generally directly connects a set of hydraulic cylinders to perform the pulling / pushing work on it, which leads to the installation of multiple hydraulic cylinders outside the device using multiple core-pulling structures. The setting of multiple sets of hydraulic cylinders not only occupies the space of the production workshop but also increases the production cost of the factory, and to propose a die-casting mold for an inverter radiator.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A die-casting mold for an inverter radiator, comprising a first mounting bracket, a second mounting bracket, a first core-pulling structure and a second core-pulling structure. A hydraulic system is provided on the first mounting bracket, and the output end of the hydraulic system is connected to the second core-pulling structure. A propulsion mechanism is provided on the second mounting bracket. The propulsion mechanism includes a first mounting frame, a movable plate, a moving rod, a first sliding block and a second sliding plate. First openings are formed on both sides of the first mounting frame. The movable plate is disposed through the first openings of the first mounting frame. A chute is formed inside the movable plate, and a sliding block is disposed inside the chute. One end of the sliding block is connected to a moving rod, and the other end of the moving rod is connected to the rod portion of the output end of the hydraulic system.

[0007] In the solution provided by the embodiment of the present application, through the cooperation of the sliding block and the moving rod of the propulsion mechanism with the telescopic part of the hydraulic cylinder on the hydraulic system, when the hydraulic system advances or withdraws the first core-pulling structure, the movable plate cooperates with the sliding block, the second spring and the sliding plate to move within the space formed by the chute and the diamond-shaped mounting plate. The movable plate will move correspondingly. When the position where the sliding block moves enters a narrow area from large to small, the movable plate drives the connecting piece and the first core-pulling structure to move towards the mold direction, so that the first core-pulling structure, the second core-pulling structure and the female mold and the male mold complete the cavity combination work. When the position where the sliding block moves enters a wide area from small to large, the movable plate is reset in cooperation with the first spring. This structure not only saves the position space occupied by installing multiple hydraulic cylinders in the workshop or outside the mold, but also reduces the production cost of the factory, and has extremely high practicability.

[0008] In a possible implementation manner, a second spring is connected to the bottom of the sliding block, and the other end of the second spring is connected to a sliding plate. The inclined surfaces at both ends of the sliding block are matched with the inclined surfaces of the inner convex parts of the mounting plate.

[0009] Through the action of the provided second spring and the sliding plate, balls are provided at the bottom of the sliding plate, so that the sliding block has a good sliding effect in the chute, and the smooth movement of the sliding block is avoided, thereby affecting the position adjustment work of the movable plate.

[0010] In a possible implementation manner, the cross-section of the mounting plate is in a diamond structure, and a second opening is transversely provided in the middle of the mounting. The length of the second opening is equal to the length of the chute.

[0011] Through such a design, a sliding cavity with wider ends and narrower middle is formed between the mounting plate and the chute, so that when the moving rod drives the sliding block to move in the chute, the position of the movable plate can be adjusted.

[0012] In a possible implementation manner, a connecting piece is provided in the middle of the outside of the mounting plate. The connecting piece includes a straight push rod and a retaining piece, and a first core-pulling structure is installed at the end of the connecting piece.

[0013] Through the provided connecting piece, when the movable plate adjusts its position, it can smoothly drive the connecting piece and the first core-pulling structure to move inside the second mounting bracket, completing the combination and extraction of the first core-pulling structure.

[0014] In a possible implementation manner, through holes are provided in the middle parts of the first mounting bracket and the second mounting bracket, and a second mounting frame is arranged outside the first mounting bracket.

[0015] Through the provided through holes, the straight push rod and the connected first core-pulling structure can smoothly move on the punch or die.

[0016] In a possible implementation manner, the second mounting frame and the hydraulic system are fixedly connected through fasteners.

[0017] By providing fasteners between the second mounting frame and the hydraulic system, the fasteners include fastening bolts and fastening nuts, the hydraulic system is stably installed on the second mounting frame, and the second mounting frame and the first mounting bracket are fixedly connected.

[0018] In a possible implementation manner, the hydraulic system includes a hydraulic cylinder, a hydraulic control element, and hydraulic accessories, and the power of the hydraulic system is provided by an external energy device.

[0019] By providing the hydraulic system, it is convenient to provide a driving force for the second core-pulling structure, enabling the device to smoothly complete the mold opening or closing work.

[0020] In a possible implementation manner, first springs are installed on both sides at both ends of the movable plate, the other ends of the first springs are connected to the inner wall of the first opening, and the inner wall of the first opening is in contact with the outer wall of the movable plate.

[0021] By providing the first springs, when the telescopic component of the hydraulic system contracts, the moving rod connected to it drives the sliding block to move towards the end of the movable plate, causing the pulling force at both ends of the movable plate to disappear. Then, under the rebounding action of the first springs that store energy in compression, the movable plate drives the connecting piece, the first core-pulling structure, and the product space of the punch or die to quickly complete the extraction work.

[0022] In a possible implementation manner, matching punches and dies are provided above and below the first mounting bracket and the second mounting bracket.

[0023] By providing the first mounting bracket and the second mounting bracket, when the structure of the produced product is relatively complex, at least two groups of first core-pulling structures and second core-pulling structures can be arranged on the device. By arranging the core-pulling structures in multiple directions, when producing complex products, the mold opening is smooth and the combination is convenient.

[0024] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0025] 1. In the present utility model, through the setting of the propulsion mechanism, when the telescopic part of the hydraulic cylinder in the hydraulic system extends, it synchronously drives the moving rod and the sliding block to move in the chute of the movable plate, so that the movable plate moves towards the mounting frame, completing the work of combining the first core-pulling structure, the second core-pulling structure with the punch or the die. The design of this structure not only reduces the number of hydraulic cylinders required for multiple groups of core-pulling structures to be installed correspondingly, but also reduces the production cost of workpieces and saves the installation space on multiple outer surfaces of the device, with extremely high practicality.

[0026] 2. In the present utility model, through the setting of the first spring, when the telescopic component of the hydraulic system contracts, the moving rod connected to it drives the sliding block to move towards the end of the movable plate, causing the pulling force at both ends of the movable plate to disappear. Then, under the rebound action of the first spring that stores energy in compression, the movable plate drives the connecting piece, the first core-pulling structure and the product space of the punch or the die to quickly complete the core-pulling work.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0034] Referring to Figures 1-4 , a die-casting mold for an inverter radiator, includes a first mounting bracket 3, a second mounting bracket 4, a first core-pulling structure 12 and a second core-pulling structure 14. A hydraulic system 5 is provided on the first mounting bracket 3, and the output end of the hydraulic system 5 is connected to the second core-pulling structure 14. A propulsion mechanism 7 is provided on the second mounting bracket 4. The propulsion mechanism 7 includes a first mounting frame 8, a movable plate 22, a moving rod 6, a first sliding block 19 and a second sliding plate 20. First openings 9 are formed on both sides of the first mounting frame 8. The movable plate 22 is disposed through the first openings 9 of the first mounting frame 8. A chute 17 is formed inside the movable plate 22. A sliding block 19 is disposed inside the chute 17. One end of the sliding block 19 is connected to a moving rod 6, and the other end of the moving rod 6 is connected to the rod part of the output end of the hydraulic system 5.

[0035] In the solution provided by the embodiment of the present application, through the cooperation of the sliding block 19, the moving rod 6 of the propulsion mechanism 7 and the telescopic part of the hydraulic cylinder on the hydraulic system 5, when the hydraulic system 5 advances or withdraws the first core-pulling structure 12, the movable plate 22 moves in the space formed by the chute 17 and the diamond-shaped mounting plate 18 in cooperation with the sliding block 19, the second spring 16 and the sliding plate 20. Accordingly, the position of the movable plate 22 will move. When the position where the sliding block 19 moves enters a narrow area from large to small, the movable plate 22 drives the connecting member 11 and the first core-pulling structure 12 to move towards the mold direction, so that the first core-pulling structure 12 and the second core-pulling structure 14 complete the cavity combination work with the female mold 1 and the male mold 2. When the position where the sliding block 19 moves enters a wide area from small to large, the movable plate 22 is reset in cooperation with the first spring 15. This structure not only saves the position space occupied by installing multiple hydraulic cylinders in the workshop or outside the mold, but also reduces the production cost of workpieces, and has extremely high practicability.

[0036] As Figure 4 shown, in a possible implementation manner, a second spring 16 is connected to the bottom of the sliding block 19, the other end of the second spring 16 is connected to a sliding plate 20, and the inclined surfaces at both ends of the sliding block 19 cooperate with the inclined surfaces of the inner convex parts of the mounting plate 18.

[0037] Due to the action of the second spring 16 and the sliding plate 20 provided, balls are arranged at the bottom of the sliding plate 20, so that the sliding block 19 has a good sliding effect in the sliding groove 17, avoiding the unsmooth movement of the sliding block 19 and thus affecting the position adjustment of the movable plate 22.

[0038] As Figure 4 shown, in a possible implementation manner, the cross-section of the mounting plate 18 is in a diamond structure, and a second opening 21 is horizontally arranged in the middle of the mounting. The length of the second opening 21 is equal to the length of the sliding groove 17.

[0039] Through such a design, a sliding cavity with wider ends and a narrower middle is formed between the mounting plate 18 and the sliding groove 17, so that when the moving rod 6 drives the sliding block 19 to move in the sliding groove 17, the position of the movable plate 22 can be adjusted.

[0040] In a possible implementation manner, a connecting piece 11 is arranged in the middle of the outer side of the mounting plate 18. The connecting piece 11 includes a straight push rod and a retaining piece, and a first core-pulling structure 12 is installed at the end of the connecting piece 11.

[0041] Through the arranged connecting piece 11, when the position of the movable plate 22 is adjusted, the connecting piece 11 and the first core-pulling structure 12 can be smoothly driven to move inside the second mounting frame 4, completing the combination and extraction of the first core-pulling structure 12.

[0042] In a possible implementation manner, through holes 13 are opened in the middle of both the first mounting frame 3 and the second mounting frame 4, and a second mounting frame 10 is arranged outside the first mounting frame 3.

[0043] Through the arranged through holes 13, the straight push rod and the connected first core-pulling structure 12 can smoothly move on the convex die 2 or the concave die 1.

[0044] In a possible implementation manner, the second mounting frame 10 is fixedly connected to the hydraulic system 5 through fasteners.

[0045] Through the fasteners between the second mounting frame 10 and the hydraulic system 5, the fasteners include fastening bolts and fastening nuts, the hydraulic system 5 is stably installed on the second mounting frame 10, and the second mounting frame 10 is fixedly connected to the first mounting frame 3.

[0046] In a possible implementation manner, the hydraulic system 5 includes a hydraulic cylinder, hydraulic control components and hydraulic accessories, and the power of the hydraulic system 5 is provided by an external energy device.

[0047] By arranging the hydraulic system 5, it is convenient to provide a driving force for the second core-pulling structure 14, so that the device can smoothly complete the mold opening or mold closing work.

[0048] As Figure 3, in a possible implementation, first springs 15 are installed on both sides at the two ends of the movable plate 22. The other ends of the first springs 15 are connected to the inner wall of the first opening 9, and the inner wall of the first opening 9 is in contact with the outer wall of the movable plate 22.

[0049] By providing the first springs 15, when the telescopic member of the hydraulic system 5 contracts, the moving rod 6 connected thereto drives the sliding block 19 to move towards the end of the movable plate 22, causing the pulling force at both ends of the movable plate 22 to disappear. Then, under the rebound action of the first springs 15 that store energy in compression, the movable plate 22 drives the connecting member 11, the first core-pulling structure 12 and the product space of the punch 2 or the die 1 to quickly complete the core-pulling work.

[0050] In a possible implementation, matching dies 1 and punches 2 are provided above and below the first mounting frame 3 and the second mounting frame 4.

[0051] By providing the first mounting frame 3 and the second mounting frame 4, when the structure of the produced product is relatively complex, at least two groups of first core-pulling structures 12 and second core-pulling structures 14 can be arranged on the device. By arranging the core-pulling structures in multiple directions, when producing complex products, the mold opening is smooth and the combination is convenient.

[0052] Working principle: During use, first, the hydraulic cylinder of the hydraulic system 5 drives the propulsion mechanism 7 connected to its rod part to move in cooperation, so that the sliding block 19 and the moving rod 6 of the propulsion mechanism 7 move in the sliding groove 17 on the movable plate 22. When the telescopic part of the hydraulic cylinder performs a propulsion or extraction action, the moving rod 6 cooperates with the sliding block 19, the second spring 16, and the sliding plate 20 in the sliding groove 17 formed by the sliding groove 17 and the diamond-shaped mounting plate 18, and moves in the space formed by the sliding groove 17 and the diamond-shaped mounting plate 18. The movable plate 22 will move accordingly. If the position where the sliding block 19 moves enters a narrow area from large to small, the movable plate 22 drives the connecting member 11 and the first core-pulling structure 12 to move towards the mounting frame direction, so that the first core-pulling structure 12, the second core-pulling structure 14 and the die 1, the punch 2 complete the cavity combination work. If the position where the sliding block 19 moves enters a wide area from small to large, then the movable plate 22 is reset in cooperation with the first spring 15. This structure not only saves the position space occupied by installing multiple hydraulic cylinders in the workshop or outside the mold, but also reduces the production cost of the workpiece, and has extremely high practicability.

[0053] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
