  • Publication number: 20150035193
    Abstract: A method of improving the appearance of foaming injection molding product includes closing the moving mold and the fixed mold and setting a clamping force on the closed mold, wherein a mold cavity is formed between the moving mold and the fixed mold. The method proceeds by inflating the mold cavity with high pressure and high temperature gas until the air pressure in the mold cavity reaches 2-25 MPa and the temperature of the high pressure and high temperature gas is between 60-200° C., then injecting molten resin that contains foaming agent into the mold cavity while continuously inflating high pressure and high temperature gas. After injection completed, stopping inflating high pressure and high temperature gas and simultaneously releasing pressure, wherein the step of releasing pressure includes the step of opening the mold.

  • Publication number: 20130255087
    Abstract: The present invention first provides a utility knife with a replaceable blade, comprising a knife handle, a blade holder, a blade and a locking device that locks the blade in the blade holder. The blade holder and the blade are enabled to switch between a first position and a second position. When the blade holder and the blade are in the first position, the blade is used for cutting operation, and when the blade holder and the blade are in the second position, both the blade holder and the blade are received in the knife handle. The utility knife further includes a restriction means which is thus arranged as, when the blade holder is in the second position and the locking device is in unlocked state, the restriction means is used for preventing the detachment of the blade from the blade holder by confining the movement of the blade relative to the blade holder.
