How to do a good job in the maintenance and maintenance of plastic molds

Plastic mold is the key to the molding of plastic products. The quality of the mold directly affects the quality of the product, such as the roughness of the surface, the tightness of the joint, etc. If there is a problem, the finished product will definitely be unqualified. Therefore, the plastic mold must be well maintained before it is not used and before use. The specific steps are as follows.

1. Before production, check whether there are impurities and dirt in each part of the mold. Use cotton gauze to scrub the paint, impurities and dirt in the mold, remove them, and remove the firmly bonded residual materials with a copper knife.

2. Reasonable selection of mold clamping force is based on the fact that no burrs are generated during product molding. Excessive mold clamping force will increase power consumption and also easily accelerate the wear speed of molds and transmission parts.

3. For guide pillars, push rods, return rods, tie rods and other mold moving parts, oil is added twice a day in summer, and oil is only added once in winter.

4. When the full-time mold maintenance work is on duty, inspect and observe the molds in production, and deal with the problems in time. When the maintenance project is handed over, they should set sail 5 to 10 minutes in advance to check the production status of the molds, especially for frequent More attention should be paid to unqualified molds and molds with many problems.

5. During production, if there is a power outage or stop due to some reasons, and the continuous stop is more than 6 hours, and the air is humid during the rainy season in the south, anti-rust oil needs to be sprayed on the forming surface, separation surface, and folding surface, and the continuous stop is more than 24 hours outside the rainy season. When the mold is used, it is necessary to spray anti-rust lubricant on the mold forming surface, separation surface, and folding and fitting surface. In storage, no heavy objects can be placed on the mold.

6. Do not hit any parts in the mold with a hammer to prevent knock marks or deformation.

7. The equipment is temporarily unused, but the injection mold should be coated with anti-rust oil, and the movable and fixed parts of the mold should not be in a pressured clamping state for a long time to prevent deformation under pressure.
