Description

Technical Field

[0001] The invention relates to the technical field of precision injection molding, in particular to an integrated self-maintenance fixture for precision machining of injection molds. Background Art

[0002] In the injection molding process, molds and fixtures are key mechanical components. The high-frequency reciprocating motion and continuous force between them require efficient lubrication to reduce friction, reduce energy consumption and maintain the normal operation of the equipment. However, in actual production, due to the insufficiency of the lubrication system or the uneven coverage of the lubricant, the following problems are easily caused: when the lubrication conditions are insufficient, the relative movement between the mold and the fixture produces excessive friction, which not only accelerates the wear of the mechanical surface, but also may cause the moving parts to deform due to local heating, thereby affecting the processing accuracy. The heat accumulation caused by friction will aggravate the temperature rise of the equipment components, resulting in thermal expansion and contraction of the mold surface and key parts of the fixture. Long-term operation may cause jamming or even equipment failure, seriously reducing production efficiency;

[0003] In existing injection mold fixtures, the lubrication system is mostly passively designed, usually relying on manual regular addition of lubricant, lacking real-time monitoring and active replenishment functions for insufficient lubrication. Since it is impossible to sense and compensate in time before the lubricant is exhausted, the equipment often runs for a long time under poor working conditions, resulting in local damage or shutdown, increasing maintenance costs and the risk of production interruption. In addition, although some automatic lubrication devices have a certain spraying function, the coverage of the lubricant is limited, and it is difficult to meet the lubrication needs of complex fixture surfaces and internal structures;

[0004] In response to the above problems, this technology proposes an integrated self-maintenance fixture for precision machining of injection molds, which integrates a lubrication deficiency monitoring mechanism, an intelligent spray compensation function, and a clean waste liquid discharge system. It can sense the lubrication status in real time during equipment operation, spray lubricating fluid in time, and enhance the lubrication effect through structural vibration, which significantly improves the equipment's operating efficiency and service life and meets the needs of efficient injection molding processing.

[0031] The lubrication mechanism 2 includes a support arm 201, one end of which is fixedly connected to the left side of the mounting plate 101, and the outer wall of the support arm 201 is slidably connected to a cover 202 via a linear motor, and the inner wall of the cover 202 is in contact with the outer walls of the mounting plate 101 and the movable plate 103;

[0032] During the use of the device, the power output device in the production line is connected to the left end of the threaded rod 104 so that the threaded rod 104 can rotate, and the left side of the mounting plate 101 is fixed so that the device is stably installed, and the connection between the mounting plate 101 and the threaded rod 104, the first plug rod 102, and the connection between the moving plate 103 and the second spring 110, the limit rod 106 and the ejector rod 109 are all sprayed with lubricant for lubrication;

[0033] When performing injection molding, the mold is installed to the right side of the mold mounting plate 107, and the threaded rod 104 is driven to rotate by the power output device. As the threaded rod 104 rotates, the movable plate 103 is pushed to move to the right, and then the movable plate 103 pushes the first spring 108, the mold mounting plate 107 and the mold to move to the right, and then the mold mounting plate 107 drives the mold to move toward the injection molding side. After the injection molding is completed, the reverse threaded rod 104 can drive the movable plate 103 to move to the left. As the movable plate 103 moves to the left, the left end of the ejector rod 109 contacts the outer wall of the mounting plate 101, and then the movable plate 103 continues to move to the left. During the process, the ejector plate 111 moves to the right relative to the movable plate 103, so that the ejector plate 111 pushes the left end of the demoulding rod 112, so that the demoulding rod 112 moves to the right to push the injection molded part in the mold, and then the injection molding process is completed;

[0034] During the injection molding process, friction heat is generated due to the reciprocating movement of the components, and since the outer side of the injection molding mechanism 1 is wrapped by the sleeve 202, the heat dissipation rate is low; thus, the lubricating fluid on its surface always maintains good lubricity;

[0035] The trigger mechanism 114 includes a limit cylinder 401, the outer wall of the limit cylinder 401 is fixedly connected to the left side of the movable plate 103, the upper side of the inner wall of the limit cylinder 401 is fixedly connected with a pressure switch 402, the inner wall of the limit cylinder 401 is slidably connected with a trigger rod 403, the pressure switch 402 is electrically connected to the control module, the lower end of the trigger rod 403 extends to the outer side of the limit cylinder 401 and is fixedly connected with a hinge head 404, the lower side of the hinge head 404 is hinged with a friction rod 405 through a torsion spring, the lower side of the friction rod 405 is in contact with the outer wall of the limit rod 106, the outer wall of the trigger rod 403 is fixedly connected with the friction rod 405, and the upper end of the friction rod 405 is fixedly connected to the lower side of the outer wall of the limit cylinder 401;

[0036] The upper right side of the sleeve cover 202 is fixedly connected with a motor 203, the output end of the motor 203 is fixedly connected with a friction wheel 204, the inside of the sleeve cover 202 is rotatably connected with a rotating shell 205 through a bearing, the side wall of the sleeve cover 202 is provided with an opening at the upper right part of the rotating shell 205, the outside of the friction wheel 204 contacts the outer wall of the rotating shell 205 through the opening on the sleeve cover 202, the outer wall of the rotating shell 205 is rotatably connected with an outer cover 206 through a bearing, the upper side of the outer cover 206 is fixedly connected with a connecting pipe 207, the upper end of the connecting pipe 207 penetrates the sleeve cover 202 and extends to the outside of the sleeve cover 202, the inner side of the rotating shell 205 is fixedly connected with a plurality of nozzles 208, the input end of the nozzle 208 is connected with the rotating shell 205 and the outer cover 206;

[0037] During the reciprocating movement of the limit rod 106, its upper side will be in continuous contact with the lower side of the friction rod 405. Under normal conditions, due to the sufficient lubrication of the lubricant on the surface of the limit rod 106, the lower side of the friction rod 405 and the outer wall of the limit rod 106 will slide relative to each other. In the case that the surface of the limit rod 106 is not lubricated enough, the friction force between the outer wall and the lower end of the friction rod 405 will push the lower end of the friction rod 405 to move rightward when the limit rod 106 moves rightward, thereby causing the friction rod 405 to support the hinge joint 404 and the trigger rod 403 to move upward, so that the upper end of the trigger rod 403 squeezes the pressure switch 402, causing the pressure switch 402 to open. 02 is triggered to start the motor 203 and the linear motor at the connection between the cover 202 and the support arm 201, so that the cover 202 moves back and forth in the left and right directions relative to the mounting plate 101. During this process, the motor 203 drives the rotating shell 205 and the nozzle 208 on the rotating shell 205 to rotate through the friction wheel 204, and the external liquid supply device pumps lubricating liquid or cleaning liquid into the rotating shell 205 through the connecting pipe 207, so that the lubricating liquid is evenly sprayed out through the nozzle 208, and the nozzle 208 is in a reciprocating and rotating state, so that the lubricating liquid is evenly sprayed on the surface of the injection molding mechanism 1, so as to achieve smooth operation of the device;

[0038] The middle part of the cover 202 is a circular structure, and the rotating shell 205 is located on the inner side of the circular structure of the cover 202. The lower left side of the circular structure of the cover 202 is fixedly connected with a drain pipe 210. The drain pipe 210 connects the lower inner part of the circular structure of the cover 202 with the outer side of the cover 202. The outer wall of the lower inner ring of the rotating shell 205 is fixedly connected with a plurality of blades 209. The control module is electrically connected with the motor 203 and the linear motor at the connection between the support arm 201 and the cover 202.

[0039] During the process of rotating shell 205 rotating and spraying cleaning liquid, excess cleaning liquid and washed away dirt will remain on the lower side of the inner part of the cover 202. During the rotation process, the blade 209 on the surface of the rotating shell 205 will mix the dirt and cleaning liquid evenly when rotating to the lower side, and then discharge them through the drain pipe 210 to avoid residual dirt in the device. Since the blade 209 only exists on one side of the rotating shell 205, the center of gravity will shift during the rotation, thereby causing a small vibration of the device, so that the gaps between the structures can be better cleaned by cleaning liquid or infiltrated by lubricating liquid.
