Plasitc Injection Mould Mold maintenance

Edit mold maintenance

1, the processing enterprises should first give each secondary mold with a resume card, detailed records, statistics of its use, care (lubrication, cleaning, rust) and damage, which can be found in which parts, components are damaged, the degree of wear to provides discovery and problem-solving information materials, and molding process parameters of the mold, the product materials used to shorten test time mold, improve production efficiency.

2, the processing enterprises should be in the injection molding machine, mold normal operation, the test mold a variety of performance, and the final shape of the plastic parts measured by this information can determine the existing state of the mold to find the cavity, , damage to the cooling system, and where the parting surface or the like, according to the information provided by plastic parts, and repair damage state is determined to measure the mold.

3, several important parts of the mold to focus tracking and detection: the ejector, is to ensure that the role of the guide member and the mold opening and closing motion of the top of the plastic parts, if any portion of jamming due to injury, will result in shutdown, it should be Often to maintain the mold thimble, guide column lubrication (to choose the most suitable lubricant), and regularly check the thimble, guide column, etc. whether the deformation and surface damage, once discovered, to be replaced; complete a production cycle, Work surface, movement, guide parts coated with professional anti-rust oil, in particular, should pay attention to with gears, rack mold bearing parts and spring mold elastic strength protection, to ensure that it is always in the best working condition; with the production The cooling channel is narrowed, the cooling channel is narrowed, the heat exchange rate between the coolant and the mold is greatly reduced, and the production cost is increased. Therefore, the flow path the clean-up should pay attention; for hot runner mold, the maintenance of heating and control systems help prevent the occurrence of a production failure, and therefore in particular Important. Therefore, after the end of each production cycle should be on the mold belt heater, bar heaters, heating probes and thermocouples with ohm meter to measure, if damaged, to be replaced, and with the mold resume Compare, make a record in order to find the problem in a timely manner, to take countermeasures.

4, to attach importance to the surface of the mold maintenance, it directly affects the surface quality of the product, the focus is to prevent corrosion, therefore, choose a suitable, high quality, professional anti-rust oil is particularly important. When the mold to complete the production tasks, should be based on different injection to take a different method to carefully remove the residual injection, copper rods, copper wire and professional mold cleaning agent to remove residual mold injection and other sediment, and then air-dried. Disable wire, steel and other hard objects to clean up, so as not to scratch the surface. If there is corrosive injection caused by the rust point, to use grinding machine grinding and polishing, and sprayed with professional anti-rust oil, and then placed in a dry mold, cool, no dust at the storage.
