Technical Field
[0001] This utility model relates to the technical field of guide column lubrication, specifically to a template guide column lubrication structure and a die-casting machine. Background Technology
[0002] In recent years, the development of new energy electric vehicles has been extremely rapid. Most of the parts and frames of these vehicles are made of aluminum alloy. Aluminum alloy parts are generally produced by die casting in molds using die casting machines, which is why die casting machines play an important role in industrial production.
[0003] Taking a three-plate die-casting machine as an example, the main mold-locking part includes three plates: the rear locking platen, the middle moving platen, and the front fixed platen, as well as four guide pillars passing through the three plates. The front fixed platen is fixed, while the middle moving platen can slide back and forth along the guide pillars under the push of a motor-driven hydraulic cylinder on the rear locking platen. After assembly, the platen guide pillars are fixed to the front fixed platen by threaded engagement with the platen guide pillar nuts. The platen guide pillars can only be removed from the front fixed platen by rotating the platen guide pillar nuts during disassembly and assembly. Therefore, the lubrication requirement at the platen guide pillars and the front fixed platen is relatively small.
[0004] Although the lubrication requirement between the template guide post and the front template is small, the portion of the template guide post protruding from the template guide post nut end face is in contact with air, making the threads on the template guide post prone to rust and corrosion. This also makes disassembling the template guide post and template guide post pressure plate very inconvenient. Therefore, periodic lubrication is necessary between the template guide post and the template guide post nut. To enable lubrication, the end face of the template guide post should be lower than the end face of the template guide post nut. A boss should be added to the template guide post pressure plate so that the boss surface fits against the end face of the template guide post, thereby forming a sealed space between the template guide post, template guide post nut, and template guide post pressure plate.
[0005] However, in actual production, it was found that adding protrusions to the template guide column pressure plate on the original basis has the following drawbacks: the processing cost of the template guide column pressure plate increases, the increased size and weight make disassembly and assembly inconvenient, and the incompatibility between different models increases the difficulty of procurement and inventory management.
[0006] To address this, a template guide column lubrication structure is proposed, which reduces material cutting and processing costs, facilitates worker assembly and disassembly, and is compatible with various machine models. Utility Model Content
[0007] This utility model proposes a template guide column lubrication structure and a die-casting machine. By providing a lubrication component on the front fixed template for lubricating the gap between the guide column and the fixed seat, it is convenient for manufacturers to manufacture and process the lubrication component. The lubrication component is set on the front fixed template, which is convenient for installation and has strong versatility. Manufacturers only need to adjust the production of the lubrication component according to the corresponding part size of the machine.
[0008] A template guide post lubrication structure designed for this purpose includes a front fixed template that cooperates with the guide post. The front fixed template is provided with a fixed seat for fixed connection with the guide post. A lubrication assembly is provided between the guide post and the corresponding fixed seat. The lubrication assembly is provided with a lubrication input end and a lubrication output end that communicates with the lubrication input end.
[0009] One end of the lubrication output end extends to the mating gap between the guide post and the fixed seat. The lubricating medium flows through the lubrication input end and the lubrication output end of the lubrication assembly to the mating gap between the guide post and the fixed seat to lubricate the mating area between the guide post and the fixed seat.
[0010] The lubrication assembly includes a template guide post pad, which has a through hole connecting to the lubrication input end. The template guide post pad has several lubricating oil grooves forming the lubrication output end along the through hole. One end of each lubricating oil groove is connected to the through hole, and the other end of each lubricating oil groove extends toward the fitting gap between the guide post and the fixed seat. The lubricating medium passes through the lubrication assembly and flows dispersedly along each lubricating oil groove into the fitting gap between the guide post and the fixed seat.
[0011] The lubrication assembly includes a template guide column pad installed on a fixed base, and the fixed base is provided with a positioning step for positioning and installing the template guide column pad.
[0012] The template guide column pad is equipped with a sealing element to seal the installation gap between the template guide column pad and the positioning step.
[0013] The lubrication assembly also includes a template guide column pressure plate, which is set on the top of the template guide column pad. A fastening assembly is provided between the template guide column pressure plate and the front fixed template. The template guide column pressure plate is fixedly connected to the front fixed template through the fastening assembly, and presses the template guide column pad and the fixed seat onto the front fixed template, so that the fixed seat presses against the guide column. Under the cooperation and shearing force between the guide column and the fixed seat, a fixed connection is formed between the guide column and the front fixed template.
[0014] An anti-rotation component is provided between the template guide column pad and the template guide column pressure plate. The template guide column pad and the template guide column pressure plate are connected by the anti-rotation component to prevent relative rotation between the guide column pad and the template guide column pressure plate.
[0015] Fasteners are provided between the template guide column pressure plate, the template guide column pad, and the guide column, and the template guide column pressure plate, the template guide column pad, and the guide column are fixedly connected by a fastener.
[0016] The template guide column pad is provided with a through hole, and the template guide column pressure plate is provided with a connection hole forming a lubrication input end. The connection hole and the through hole are correspondingly provided and used to connect the lubrication joint. A first sealing gasket is provided between the template guide column pad and the template guide column pressure plate corresponding to the through hole to seal the mating gap between the end faces of the connection hole and the through hole.
[0017] The template guide column pad is provided with an assembly hole for connecting with the guide column. A second sealing gasket is provided between the template guide column pad and the guide column corresponding to the assembly hole to seal the mating gap between the template guide column pad and the guide column.
[0018] A die-casting machine includes a machine body, on which the above-mentioned template guide column lubrication structure is provided, and the guide column is provided with a moving template and a locking template.
[0019] The beneficial technical effects of this utility model are as follows:
[0020] The guide post end face and the template guide post pad form a small, sealed space, effectively lubricating the guide post and preventing corrosion and rust on the guide post and fixing seat, as well as damage during disassembly, without increasing the material processing cost, size, or weight of the template guide post pressure plate. Furthermore, the template guide post pad is interchangeable between different models, requiring only that the diameter of the pad is greater than or equal to the maximum diameter of the threaded end of the template guide post of the compatible model, and that the template guide post nut (fixing seat) has a circular groove of the same diameter and depth for embedding the pad.
