Automotive Injection Mold Maintenance Skills

Automotive Injection Mold maintenance should note the following four points:

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.

2, the processing enterprises should be in the Automotive Injection Molding machine, the normal operation of the mold, 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, 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, Automotive Injection Mold 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 becomes narrower, greatly reduces the heat exchange rate between the coolant and the mold, increases the production cost of the enterprise, so the flow channel Of the clean-up should be taken seriously; for hot runner mold, the heating and control system maintenance is conducive to prevent the occurrence of production failures, so especially Important. Therefore, after the end of each production cycle should be on the mold belt heater, bar heater, heating probe and thermocouple with ohm meter to measure, if damaged, to be replaced, Automotive Injection Mold and with the mold resume Compare, make a record, in order to find the problem timely, 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, sAutomotive Injection Mold hould 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 grinder grinding, and sprayed with professional anti-rust oil, Automotive Injection Mold and then placed in a dry mold, cool, no dust at the storage.
