Do you know how to maintain injection molds? let me tell you

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 Provide information to find and solve the problem, as well as the molding process parameters of the mold, the product used to shorten the mold test time, improve production efficiency. injection mold design company


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, , Cooling system and sub-surface damage, etc., according to the information provided by the plastic parts, you can determine the damage to the mold state and maintenance measures.

3, to focus on several important parts of the mold to track the detection: the top, the role of the guide parts to ensure that the mold opening and closing movement and plastic parts of the top, if any part of the damage due to injury and stuck, 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 timely identify problems and take corrective actions. injection mold design Suppliers

4, pay attention to the maintenance of the mold surface, it directly affects the surface quality of the product, the focus is to prevent corrosion, therefore, the choice of 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. Disabling wire, steel bars and other hard objects to clean up, so as not to scratch the surface. If rust pitting corrosion caused by the injection, to a grinder polishing, and sprayed on professional rust oil, and then the mold was placed in a dry, cool, no dust at storage.
