Injection molding machine thickness printing adjustment method
2024-10-28
1. mold adjustment
1. Adjust the thickness of the mold: adjust the thickness of the mold according to the design requirements and process requirements, that is, tighten the template screws and adjust the size of the template gap.
2. Adjust the parallelism of the template: by adjusting the horizontal and vertical parallelism of the template, the mold is stressed evenly, so as to adjust the thickness of the print.
3. Adjust the surface of the template: the unevenness of the surface of the template will cause the thickness of the print, which can be adjusted by grinding, polishing and other methods.
2. shot adjustment
1. Adjust the injection speed: the injection speed is too fast or too slow will lead to uneven thickness of the product, which needs to be adjusted according to the die size and material characteristics.
2. Adjust the injection pressure: increase the injection pressure to adjust the wall thickness of the product, reduce the injection pressure to adjust the thickness of the product wall.
3. Adjust the amount of injection: the adjustment of injection time and injection amount can also change the thickness of the product.
3. cooling adjustment
1. Adjust the cooling time: If the product is not fully cooled, thermal rebound and deformation will occur. Adjusting the cooling time can effectively solve this problem.
2. Adjust the cooling position: adjust the setting position of the cooling system according to the structure of the mold and the characteristics of the material.
3. Adjust the amount of cooling water: increasing the amount of cooling water can accelerate the cooling of the product, and reducing the amount of cooling water can delay the cooling rate.
4. impression inspection
During the operation of the injection molding machine, it is necessary to check the impression regularly. If there is uneven thickness, it should be adjusted in time. X-ray inspection or CT inspection can also be performed on the product to determine the impression.
In general, the thickness of the injection molding machine printing adjustment needs to consider the mold, injection, cooling and other factors, through good operating skills and experience, as well as continuous testing and adjustment, in order to ensure the quality of the product and process requirements.
