An injection molding system includes an injection molding apparatus that performs injection molding, a first conveyor apparatus on one side of the injection molding apparatus to eject and insert a first mold through a first opening of the injection molding apparatus, and a second conveyor apparatus located on a second side of the injection molding apparatus to eject and insert a second mold through a second opening of the injection molding apparatus, where the improvement of the injection molding apparatus includes a first door to cover the first opening, a second door to cover the second opening, and a controller that prohibits injection molding with the first mold in a case where the second door is opened.

An injection molding system includes an injection molding apparatus that performs injection molding with a die and a conveyor apparatus on one side of the injection molding apparatus that inserts the die into the injection molding apparatus, where the conveyor apparatus includes an actuator connectable to the die. The injection molding system also includes a die detection unit that detects the conveyed die, an actuator detection unit that detects a state of the actuator, and a controller that controls the conveyor apparatus to prohibit a conveying operation of the die based on detection results by the die detection unit and the actuator detection unit.

A mold conveyance guide apparatus includes: a linear guide that is attached along a conveyance direction of a mold to a mold attachment surface of at least one of a fixed platen or a movable platen to which the mold is fixed; a slider that is movably attached to the linear guide; and a coupling arm that is swingably attached to the slider in a direction coming closer to or separating from the mold attachment surface and is coupled to the mold in an engageable and disengageable manner.

A mold assembly includes a services block and a cavity plate defining at least a portion of a molding cavity. A quick connection mechanism can connect and disconnect the plate and the services block. The cavity plate may include a base block and a mold cavity block. A mold assembly may include two opposed combinations of such a service block and a cavity plate each mounted to an opposed platen. The base block may include a quick connection device operable connect with and disconnect from a quick connection device on the services block. A services channel in the cavity plate may connect with and disconnect from a service channel in the services block with a quick connection mechanism. A molding system may include a plurality of such cavity plates, each operable to connect with and disconnect from the same services block.

A mold for injection molding, the mold comprising a first member, a second member configured to form a first cavity corresponding to a first molded part by combining the second member with the first member, and wherein the improvement to the mold includes a third member configured to form a second cavity corresponding to a second molded product by combining the third member with the first member.

A method for manufacturing a molded part with an injection molding machine and a conveying apparatus while changing between multiple molds, the method including conveying a first mold to a molding operation position in the injection molding machine, securing the first mold at the molding operation position with a platen, fixing the platen to the first mold, opening the first mold, ejecting a molded part from the first mold, placing the first mold into a state where the first mold is slightly opened, injecting a molding material into the first mold, applying pressure to the first mold by closing the slight opening of the first mold, releasing the platen from the first mold, conveying the first mold from the molding operation position to the conveying apparatus, and cooling the first mold on the conveying apparatus.

A plastic molding system comprises: dispensing, pre-shaping and shaping cells and a transport subsystem. The dispensing cell has a station for dispensing a dose of plastic feedstock. The pre-shaping and shaping cells each comprise a plurality of stations for shaping the workpiece into a preform shape and into a final shape, respectively. The transport subsystem advances a workpiece along a selected one of a plurality of process paths to form a molded article. Each of the plurality of process paths is defined by a combination of stations of the dispensing cell, the pre-shaping cell and the shaping cell.

There is provided a mold conveying guide device for use in replacement of a mold by conveying the mold into and out of a mold fixing position in an injection molding machine. A connecting arm is attached to the mold and projects in a direction in which the mold is conveyed into the mold fixing position. A guide roller is rotatably supported at a tip end portion of the connecting arm. The guide roller is configured to rotate while being in contact with a mold attaching surface of at least one of a fixed platen and a movable platen, and configured to guide the mold such that the mold can come close to or move away from the at least one of the fixed platen and the movable platen.
