Method for taking out products remaining in mold cavity


Plastic mold knowledge-the method of taking out the products remaining in the mold cavity:

  • 1. Use a brass sheet to hard squeeze into the gap between the product and the mold, pry the product out of the cavity, but use this method with non-ferrous alloy molds with caution.
  • 2. In order to achieve this purpose, there should be a brass sheet on the injection molding machine (for example, a brass sheet with a thickness of 3MM, a width of 300MM, and a knife-shaped front end)
  • 3. Using a screwdriver as a substitute will cause major damage to the mold.
  • 4. For products that cannot be cut or split, use the brass sheet mentioned above to directly tap the product with a hammer. However, this may cause the cavity surface to be recessed, so it can only be on the surface of the product and the surface of the model. Crack, do not scratch the surface of the cavity.

  • 5. In order to cut the product, there is also a method of heating with a blowtorch directly, which is only effective for large-scale occasions. But be careful to stay away from combustible materials. For small-sized applications, use the “35 method of removing the sprue remaining in the sprue, point 4” method.
  • 6. If there is a small part of the product residue that cannot be removed no matter how to get it, use the solvent of this material (such as acetone, etc.) to coat it, and knock it out with a brass rod after it is dissolved, but be careful not to get the solvent close to the fire.
  • 7. Remove the mold cavity surface of the residual product, wipe it clean with a cloth and spray the mold release agent. However, it should be noted that the release agent has an impact on the secondary processing (coating, welding, etc.) of the product, so be careful when using it.
