Multi-mold injection molding requirements: color injection mold design is broadly divided into two categories: the first category there are two cavities, the use of rotating shift pattern pieces to Semis die cavity 180 to another, its benefits are the first and the second step can be carried out simultaneously; the other is a single cavity mold color paper, semi-finished products, together with mold rotates 180 degrees together. Shenzhen-color design is relatively simple mold, but productivity reduced accordingly. As the mold or semi-finished products need to turn color mold, mold design and therefore require more precision injection molding machine. The reason that occur during the injection molding burr of: (1) the real machine clamping force shortage. When selecting the injection molding machine, the machine's rated clamping force must be greater than the longitudinal tension of the projected area of ??the injection molded article in the injection formation, or will result in expansion mode, the occurrence of burrs. (2) adjusting the clamping device to find the color die poor, the toggle mechanism is no straight, left or right or up and down to produce uneven mold, mold parallelism phenomena can not be achieved while the mold is closed one side and the other side does not close tight posted circumstances, will appear flash injection. (3) poor parallelism of the mold itself, or is not inserted parallel or non-parallel to the template, or rod uneven force distribution, deformation unevenness, which will not close and result in clamping burrs. (4) loopback badly worn only; spring nozzle spring failure; cylinder or screw wear too much; the feed inlet cooling system failure caused by "bridging" phenomenon; it is set less barrel injection quantity, the cushion is too small, etc. may cause flash repeatedly, must be promptly repair or replacement of parts.
