How to disassemble the screw of bmc injection molding machine accurately
In addition to the standardized use of bmc injection molding machine brand for production, injection molding workers must also grasp the disassembly and maintenance methods in case of equipment failure. During the production of the injection molding machine, the screw of the injection molding machine will also be damaged due to raw materials, temperature and operating errors. In this case, how to disassemble the screw for replacement? Here is a summary of the following procedures and methods.
1. Disassembly process and method of injection molding machine screw:
1. First, the beer machine heats up the barrel and adjusts the temperature to the temperature value of the epoxy resin, then cuts off the heating power supply and removes the nozzle and its connection with the barrel;
2. Reduce the injection speed and injection working pressure of the plastic injection molding machine equipment, set the injection and flow injection working pressure to a scale of nearly 0, and separate the connection between the rotating shaft and the parts behind the screw;
3. Dismantle the connecting flange and rotate the screw to shift it. At this time, the rubber of the bmc injection molding machine needs to be backed up to the exact position;
4. When the barrel is exposed at the top of the screw head, immediately remove the screw teeth connected to the screw head, and then successively remove the electric heating ring, nozzle and front barrel;
5. Remove the check ring and seal ring in the screw. Pay attention to the fact that the removal of screw can not be done in the form of slamming, and special removal tools should be used instead. Do the "injection" position. In the specific steps, push the screw forward, then "shoot back", and then reverse the injection base. Pay attention to the need to place blocks between the injection base and the screw, and repeat this until the screw is taken out.
2. Repair and troubleshooting of the horizontal screw of the bmc injection molding machine. The removed screw can be inspected for its damage. If it is only slightly scratched and damaged, the damaged part can be repaired by grinding and polishing. If it is already seriously damaged, it is necessary to check the cause to see if the damage of the screw is caused by common faults, so as to harm the later production and manufacturing.
