Abstract
Description
A molding machine anti-deviation guide assembly Technical Field
[0001] This application relates to the field of molding machine technology, and more specifically, to a molding machine anti-deviation guide assembly. Background Technology
[0002] A molding press is an industrial device that uses pressure to shape material within a mold. It is widely used in plastics processing, metal stamping, and rubber pressing. Its core function is to utilize the high pressure generated by the closure of the upper and lower molds to solidify or deform the material within the cavity, thereby obtaining a product with specific shape and properties. In this process, the guiding assembly is a crucial structural element for achieving precise machining in the molding press.
[0003] Traditional sliding guide structures are prone to surface oil film damage under high-frequency friction, leading to direct metal-to-metal contact, increased wear, and widened clearances. Current lubrication methods rely on manual, periodic lubrication, which suffers from untimely maintenance and uneven oil distribution. Furthermore, traditional oil circuit designs struggle to ensure uniform lubrication penetration to the friction surfaces under complex operating conditions, resulting in localized lubrication failure. These problems create a vicious cycle, increasing the risk of mold misalignment, requiring frequent equipment downtime for maintenance, increasing production costs, and reducing product yield. Summary of the Invention
[0004] To address the aforementioned issues, this application provides a molding machine anti-deviation guide assembly.
[0005] The anti-deviation guide component for a molding machine provided in this application adopts the following technical solution:
[0006] A molding machine anti-deviation guide assembly includes a placement plate disposed above the machine base, and a guide mechanism is provided above the placement plate;
[0007] The guiding mechanism includes guide rods, and the number of guide rods is set to multiple and fixed around the placement plate by bolts. Each guide rod has a slider slidably connected to its outer wall, and each slider has a lubrication component on one side.
[0008] Each lubrication assembly includes a lubrication box, the bottom of which is conical. Inside the lubrication box is a flow divider, which is inclined and has multiple oil inlet holes.
[0009] Through the above technical solution, the lubrication assembly achieves the function of automatically drawing and pressing oil into the reservoir, thereby delivering the lubricating oil to the lubrication box to lubricate the guide rod and slider. This automatic lubrication method requires no manual intervention, avoiding problems such as untimely maintenance and uneven oil volume when manually adding lubricating oil in the traditional way, thus improving the efficiency and reliability of lubrication.
[0010] Furthermore, the tops of multiple guide rods are bolted to a fixing plate, and a cylinder is mounted on the top of the fixing plate.
[0011] Furthermore, the output end of the cylinder is fixedly connected to an upper template, and the outer side of the upper template is fixedly connected to multiple sliders.
[0012] Furthermore, multiple liquid storage cylinders are fixedly connected to the bottom of the fixed plate, and pressure plates are slidably connected inside the multiple liquid storage cylinders. Connecting rods are fixedly connected to the bottom of the multiple pressure plates.
[0013] Furthermore, one end of each link extends through to the outside of the corresponding liquid storage cylinder and is fixedly connected to a push plate, and the outer end of each link is fixedly connected to a counterweight.
[0014] Furthermore, multiple push plates are located above the upper template, and multiple lubrication boxes are respectively fitted and fixed on the outer wall of the corresponding guide rod.
[0015] Furthermore, each liquid storage cylinder is connected to an infusion pipe at one end, and the end of each infusion pipe away from the liquid storage cylinder is connected to the corresponding lubrication box.
[0016] Through the above technical solution, the conical shape at the bottom of the lubrication box, the internal inclined flow divider, and the oil inlet hole ensure that the lubricating oil is evenly distributed to the friction surfaces of the guide rod and the slider. Uniform lubrication effectively reduces dry friction and localized wear, thereby lowering the risk of mold misalignment and reducing equipment maintenance costs.
[0017] Furthermore, a controller is located on top of the base, and the controller is electrically connected to the cylinder.
[0018] Through the above technical solution, the controller realizes the automated control of the molding process.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] (1) This utility model realizes the function of automatic oil suction and oil pressure of the liquid storage cylinder through the setting of the lubrication component, and then delivers the lubricating oil to the lubrication box to lubricate the guide rod and the slider. This automatic lubrication method does not require manual intervention, avoids the problems of untimely maintenance and uneven oil volume when manually adding lubricating oil in the traditional way, and improves the efficiency and reliability of lubrication;
[0021] (2) This utility model, through the conical design at the bottom of the lubrication box, the internal inclined distribution plate, and the oil inlet hole, enables the lubricating oil to be evenly distributed on the friction surfaces of the guide rod and the slider. Uniform lubrication can effectively reduce dry friction and local wear, thereby reducing the risk of mold displacement and lowering the maintenance cost of the equipment. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] Referring to Figures 1-5, a molding machine anti-deviation guide assembly includes a placement plate 2 disposed above the machine base 1, and a guide mechanism is provided above the placement plate 2;
[0030] The guiding mechanism includes guide rods 3, and the number of guide rods 3 is set to multiple, and they are fixed around the placement plate 2 by bolts. Each guide rod 3 has a slider 7 slidably connected to its outer wall, and each slider 7 has a lubrication component on one side.
[0031] Each lubrication assembly includes a lubrication box 15, the bottom of which is conical. Inside the lubrication box 15 is a flow divider 16, which is inclined and has multiple oil inlet holes 17.
[0032] Referring to Figures 3 and 4, multiple liquid storage cylinders 13 are fixedly connected to the bottom of the fixed plate 6. Pressure plates 12 are slidably connected inside the multiple liquid storage cylinders 13. Connecting rods 11 are fixedly connected to the bottom of the multiple pressure plates 12. One end of each connecting rod 11 extends through to the outside of the corresponding liquid storage cylinder 13 and is fixedly connected to a push plate 9. A counterweight 10 is fixedly connected to the outer end of each connecting rod 11. The multiple push plates 9 are located above the upper template 4. Multiple lubrication boxes 15 are respectively sleeved and fixed on the outer wall of the corresponding guide rod 3. An infusion tube 14 is connected to one end of each liquid storage cylinder 13. The end of each infusion tube 14 away from the liquid storage cylinder 13 is connected to the corresponding lubrication box 15.
[0033] When the molding machine is working, the controller 8 controls the cylinder 5 to move, and the output end of the cylinder 5 drives the upper template 4 to move vertically up and down. When the upper template 4 rises and resets, the slider 7, which is fixedly connected to its outer side, slides upward along the guide rod 3. When the upper template 4 contacts the push plate 9, the push plate 9 also rises, pushing the connecting rod 11 and the pressure plate 12 downward to squeeze the lubricating oil in the liquid storage cylinder 13. The squeezed lubricating oil is delivered through the infusion pipe 14 to the lubrication box 15 fitted on the outer wall of the guide rod 3. The lubricating oil then falls onto the distribution plate 16. Because the distribution plate 16 is inclined, and the diameter of the oil inlet hole 17 on the distribution plate 16 is smaller at the end near the infusion pipe 14 and larger at the end farther away, the smaller diameter end slows down the oil flow rate on the near side through flow restriction, while the larger diameter end reduces the oil outlet resistance on the far side. This forces the lubricating oil to be evenly distributed along the length of the distribution plate 16, flowing evenly from the bottom of the lubrication box 15 to the outer wall of the guide rod 3. As the slider 7 rises and falls with the upper template 4, it is evenly carried into the mating gap between the guide rod 3 and the slider 7, forming a continuous oil film. Due to the isolation effect of the oil film, direct metal-to-metal wear is greatly reduced, and the mating gap can be kept stable for a long time.
[0034] When the upper template 4 moves downward, the counterweight 10 is fixedly connected to the outer end of the connecting rod 11. The gravity of the counterweight 10 will cause the connecting rod 11 to move downward, thereby driving the pressure plate 12, which is fixedly connected to the top of the connecting rod 11, to slide downward in the liquid storage cylinder 13, so that the upper template 4 can rise again to push the push plate 9 and realize the process of circulating lubrication.
[0035] One end of the liquid storage cylinder 13 is connected to a refueling pipe (which is existing technology and is not shown in the figure). After the molding machine has been used for a period of time, it can be replenished through the refueling pipe.
[0036] The lubrication system enables the reservoir 13 to automatically draw and pressurize oil, thereby delivering the lubricating oil to the lubrication box 15 to lubricate the guide rod 3 and the slider 7. This automatic lubrication method eliminates the need for manual intervention, avoiding problems such as untimely maintenance and uneven oil distribution that occur with traditional manual lubrication, thus improving lubrication efficiency and reliability.
[0037] The conical shape at the bottom of the lubrication box 15, the inclined internal flow divider 16, and the oil inlet 17 ensure that the lubricating oil is evenly distributed on the friction surfaces of the guide rod 3 and the slider 7. This uniform lubrication effectively reduces dry friction and localized wear, thereby lowering the risk of mold misalignment and reducing equipment maintenance costs.
[0038] Referring to Figures 1-3, the top ends of multiple guide rods 3 are connected to a fixing plate 6 by bolts. A cylinder 5 is provided on the top of the fixing plate 6. The output end of the cylinder 5 is fixedly connected to an upper template 4. The outer side of the upper template 4 is fixedly connected to multiple sliders 7.
[0039] When the cylinder 5 pushes the upper template 4 to move up and down, the slider 7 will slide up and down along the guide rod 3.
[0040] The guide rod 3 is connected to the fixing plate 6 and the placement plate 2 by bolts. When the guide rod 3 is worn or deformed due to long-term use, there is no need to disassemble the entire machine structure. You can simply loosen the bolts to quickly disassemble one or more guide rods 3 for replacement.
[0041] As an existing technology, the molding process of a molding machine (such as material filling, mold closing, pressure forming, demolding, etc.) is already common technical content known to those skilled in the art, and will not be elaborated here.
[0042] Referring to Figures 1-2, a controller 8 is provided on the top of the base 1, and the controller 8 is electrically connected to the cylinder 5.
[0043] When the molding action needs to be performed, the controller 8 sends a start command to the cylinder 5, and the piston of the cylinder 5 pushes the upper mold plate 4 downward. After reaching the preset position, the controller 8 sends a stop command, the cylinder 5 stops moving and maintains pressure. After the molding is completed, the controller 8 controls the cylinder 5 to drive the upper mold plate 4 to reset, so as to realize the automated control of the molding process.
[0044] Working principle: When the molding machine is running, the controller 8 first receives external instructions and converts them into electrical signals to start the cylinder 5. Its output end drives the upper template 4 to move vertically downward. The slider 7 on the outside of the upper template 4 slides synchronously along the guide rod 3. When the upper template 4 descends to the preset position, the controller 8 sends an instruction to stop the cylinder 5 and maintain the pressure to complete the molding action.
[0045] After molding is completed, the controller 8 controls the cylinder 5 to drive the upper template 4 to rise and reset, and the slider 7 slides upward along the guide rod 3. When the upper template 4 contacts the push plate 9 and drives it to rise, the push plate 9 pushes the pressure plate 12 to slide downward in the liquid storage cylinder 13 through the connecting rod 11, squeezing the lubricating oil in the cylinder. The pressurized oil is transported to the lubrication box 15 through the inlet pipe 14. The inclined flow divider 16 inside the box, through the aperture gradient of the oil inlet hole 17, uses the flow limiting and pressure reducing effect to force the lubricating oil to be evenly distributed along the length of the flow divider 16. The conical structure at the bottom of the lubrication box 15 guides the oil to flow to the friction surface between the guide rod 3 and the slider 7. During the process of the slider 7 rising and falling with the upper template 4, the lubricating oil is carried into the mating gap to form a continuous oil film, which isolates the metal from direct contact, reduces wear, and stabilizes the mating gap.
[0046] When the upper template 4 descends again, the push plate 9 separates from the upper template 4. The counterweight block 10 at the outer end of the connecting rod 11 pulls down the connecting rod 11 due to gravity, causing the pressure plate 12 to slide downward in the liquid storage cylinder 13, which is to reserve oil for the next extrusion.
[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
