  • Patent number: 11072102
    Abstract: Non-time dependent measured variables are used to effectively determine an optimal ejection time of a part from a mold cavity. A system and/or approach may first measure at least one non-time dependent variable during an injection molding cycle. The part is ready to be ejected from the mold upon the measured variable reaching a threshold value indicative of, for example, a part temperature dropping below an activation temperature.

    Abstract: Non-time dependent calculated variables based on measured strain are used to effectively determine an optimal hold profile for an expanding crosslinking polymer part in a mold cavity. A system and/or approach may first inject molten expanding crosslinking polymer into a mold cavity, then measure strain at the mold cavity or at another location within the injection molding system, and then calculate at least one non-time dependent variable during an injection molding cycle. Next, the system and/or method commences a hold profile for the part, and upon completing the hold profile, the part is ejected from the mold cavity, whereupon a cure profile is commenced.

    Abstract: A holding member can be made to move up and down with long strokes by means of short vertical strokes so that the overall arrangement can be downsized and lightweight. Additionally, the holding member can be held to a constant attitude and the overall arrangement can be simplified to reduce the cost. A swing arm is adapted to be swung between the metal mold at a resin molding machine and the outside of the resin molding machine by means of a rotary shaft rotating in response to a vertical motion of an elevating body relative to a vertical frame and, at the same time, a fitting member is adapted to be driven to rotate in response to the swinging motion of the swing arm in order to control the attitude of a vertical arm so as to make its axial line aligned with the vertical direction.

  • Patent number: 8309010
    Abstract: A process for production of a heat-resistant hollow article made of a polylactic acid containing resin by using a mold which includes a female mold portion having a concavity, a male mold portion having a convexity and a stripper plate having an edge-forming part. The surface of the mold facing the cavity is heated to a temperature corresponding to a crystallization temperature of the polylactic acid containing resin. The male mold portion and the stripper plate are moved away from the female mold portion when a temperature T(° C.) of the resin detected by an infrared temperature sensor is in the range of T=(t+3.5)±1.5 (t(° C.) is the surface temperature of the mold). Gas is introduced between an inner surface of the hollow article and the male mold portion, and the hollow article is taken out of the mold by advancing the stripper plate toward the hollow article.

  • Patent number: 8002532
    Abstract: Force from an electrically operated ejector mechanism of a molding machine is selectably supplemented by operation of second actuators. Second actuators are advantageously fluid (hydraulic or pneumatic) operated to supplement force provided by an electrically operated primary actuator when the ejector mechanism is driven to advance ejector members into cavities of a mold assembly. The second actuators may be enabled to be operated during automatically controlled execution of a machine cycle of operation and may be operated in response to operator selections when machine operation is controlled manually.

  • Patent number: 7946836
    Abstract: An injection molding machine and a mold are used to form batches of hallow parts, such as PET preforms. An end of arm tool transfers the molded preforms from the mold to a temperature conditioning station having a conveyor. The batch of molded preforms is received and retained on the end of arm tool by an array of cooling tubes that are attached to a number of identical cooling tubes carrier devices. The conveyor is adapted to receive the carrier devices and the cooling tubes loaded with molded preforms from the end of arm tool. The conveyor is also adapted to transfer rapidly the carrier devices and the empty cooling tubes into the end of arm tool before the end of arm tool is moved back into the molding area to receive subsequent batches of molded preforms.

  • Patent number: 7896636
    Abstract: A support apparatus of an injection-molding machine has a neural network that receives test molding data corresponding to molding conditions and a quality value obtained by measuring a non-defective molded article, and that determines a quality prediction function based on the received test molding data. A computer calculates a predicted value of the quality value using the quality prediction function. An input apparatus inputs into the neural network fixed values for the molding conditions except for a selected at least one of the molding conditions, and inputs a target value of the quality value. A graph generator generates a graphical relationship between the selected at least one molding condition and the predicted value. A graph correction unit corrects the graphical relationship generated by the graph generator on the basis of the target value.
