Manufacturing a molded part using one injection molding machine while changing between multiple molds includes performing, at a molding operation position in the injection molding machine, clamping, injection, and dwelling of a mold, conveying the mold from the molding operation position and performing a process of cooling the mold at a position different from the molding operation position, conveying the mold to the molding operation position, opening the mold, and ejecting a molded part from the mold, wherein, before performing the first step for a first mold, a molded part previously ejected from a second mold is placed into the first mold that has been opened.

A method for injection molding comprises forming a set of first articles in a mold of an injection molding machine and forming a set of second articles in the mold of the injection molding machine. The method includes transferring the set of first articles from the mold to a first set of first receivers of a tooling plate, and then moving the first set of first receivers to align with the set of second articles. Thereafter the set of second articles is transferred from the mold toward the first set of first receivers and into assembled condition with the set of first articles held in the first set of first receivers.

There is provided a teaching method for a system for taking out a molded product. A projected image obtained by projecting an attachment mounted to an elevating frame onto a virtual plane, or a maximum-dimension virtual projected image of the projected image, is displayed as is superposed on the virtual plane, the virtual plane including a captured image of an opening end surface of a die that is opened, the captured image being captured by a single imaging device, before the attachment is advanced into the die. The range of the die that is opened in which the attachment is to be lowered is checked through visual observation.

A method of estimating a normal vector to an attachment mounted to an approach frame of an apparatus for taking out a molded product and a normal vector to a die mounted to a molding machine is provided. A normal vector to a take-out head is estimated through computation using a coordinate/depth determination section and a normal vector computation section on the basis of depth data or coordinate data on three mounting members. Three or more extending portions are specified from the image, the extending portions being each a part of a fixed die or a movable die or a part of a surrounding component and extending in a direction that coincides with the open direction for the dies. A normal vector to the die is estimated through computation on the basis of the depth data or coordinate data on the specified extending portions.

An injection molding system capable of easily calculating relative position information between a movable part of an injection molding machine and a movable part of a peripheral device is provided. A first control unit 110 of an injection molding machine 2 calculates first relative position information which is relative position information of a first movement position M1 set to a movable part 50 in relation to a first reference position K1 set to a first connection portion 80. A second control unit 210 of a robot 3 calculates second relative position information which is relative position information of a second movement position M2 set to a hand 65 in relation to a second reference position K2 set to a second connection portion 85. The first control unit 110 and the second control unit 210 calculate inter-drive-unit relative position information which is relative position information between the first movement position M1 and the second movement position M2 on the basis of the first relative position information and the second relative position information.

A method for receiving and ejecting molded articles includes: (a) drawing air from a cooling tube cavity into an air channel through a plate bore to draw at least a portion of a molded article into the cavity; (b) moving a valve within the plate bore from a first position for conducting air from the cavity to the air channel to a second position for reducing air flow through the plate bore relative to the first position; and (c) when the valve is in the second position, urging pressurized air from the air channel to the cavity through the plate bore to assist ejection of the molded article from the cavity.

The three-dimensional geometry of an attachment is measured before work is started. A maximum dimension of a take-out head 60 in the X direction, a maximum dimension of the take-out head 60 in the Y direction, and a maximum dimension of the take-out head 60 in the Z direction are measured on the basis of an image of the take-out head 60 captured by at least imaging devices C11 and C12 before the take-out head 60 starts work with the take-out head 60 being mounted to an elevating frame 59B of an apparatus 5 for taking out a molded product, as an orthogonal three-axis robot.

An injection molding device (1) for producing plastic parts (2) consisting of one or more material components is provided. The injection molding device (1) comprises an injection mold (3) having a center part (5) that is rotatable about a first axis of rotation (4), which center part is arranged between a first and a second mold half and which can be moved relative to said mold halves in a first direction. The center part (5) has cavities (7) on the lateral surfaces (6). A retaining device (10) is used to retain the center part (5) in the injection molding device (1). A transfer device (16) is arranged laterally next to the center part (5) at least in an open position and is used to transfer plastic parts (2) into a storage means (28).

A dialyzer housing manufacturing system includes a molding device configured to mold a dialyzer housing, and a tool coupled to a robotic arm and configured to retrieve the dialyzer housing from the molding device after the dialyzer housing is molded. The tool includes a frame, a first suction cup connected to a first portion of the frame, and a second suction cup connected to a second portion of the frame, the second suction cup being oriented about 70 degrees to about 110 degrees relative to the first suction cup.

An image display device displays an image such that a pair of reference symmetric structure portions, e.g. a pair of guide pins, are included in a captured image displayed on a display section, the pair of reference symmetric structure portions being located symmetrically with respect to a second virtual plane which extends in the opening direction and the vertical direction and includes a virtual center line of the molding apparatus which extends in the opening direction. A teaching execution section is used to determine the lateral position of an approach frame in the take-out operation by changing the position of the approach frame such that the center of an imaging range is located at a middle position between the pair of reference symmetric structure portions included in the captured image.
