Provided is a method for manufacturing an optical receptacle with which the occurrence of bending of a guide pin hole can be suppressed. The method for manufacturing an optical receptacle of the present invention includes an injection step of injecting a resin through a resin injection port of a mold into a cavity of the mold, and a solidification step of solidifying the resin in the cavity of the mold. The cavity of the mold has a protruding portion for forming a recessed portion in a main body of an optical receptacle, a pair of pins for forming a pair of guide pin holes in the main body of the optical receptacle, and a pair of pin-retaining portions. In the injection step, the mold during the injection of the resin is in a state in which the pair of pins are respectively disposed on two end sides of the protruding portion, the resin injection port is disposed so that the resin flows from one end side of the pair of pins toward opposing faces of the pins that oppose each other, one of the pin-retaining portions is disposed in contact with a side of a corresponding one of the pins that is opposite to the opposing face thereof, and the other of the pin-retaining portions is disposed in contact with a side of the other of the pins that is opposite to the opposing face thereof.

In an aspect, a mold stack may comprise two adjacent components, one at least partially defining a vent adjustable between a molding configuration and a cleaning configuration. A junction of the components may be adjustable between a molding configuration, wherein mating faces contact one another to define a parting line, and a cleaning configuration, wherein mating faces are separated to create a molding cavity extension therebetween and an auxiliary melt barrier prevents uncontrolled flashing from the extension. In another aspect, a mold shut height adjustment mechanism may include a mold component movable along an operational axis of the mold, a stop member, movable along the axis relative to the mold component, having first and second stops for providing first and second gaps on the front and back sides, respectively, of the mold component when the stop member is deployed, and a spacer for use in selectively deploying the stop member.

An injection molding mold apparatus including: a first mold and a second mold forming a cavity into which thermoplastic resin is configured to be injected; a slide mold provided on at least one of the first and second molds, capable of moving back and forth in a direction intersecting a mold opening and closing direction, and forming a part of the cavity while being in pressure contact with an insert member during molding; and a pressing member provided at a portion where the slide mold is not provided among portions of the first and second molds that face each other and at a position corresponding to a tip end portion of the slide mold, being movable in the mold opening and closing direction, and pressing and moving the tip end portion in the mold opening and closing direction when the first and second molds are closed.

Provided is an injection mold and a method of injection molding having a molding core system. The molding core system including a plurality of co-operable components manipulable between a first molding position at which the core system is fully deployed and a second position in which the core system is configured to axially retract and radially contract into a second drawing position, the outer shape of said core system being substantially complementary to the inner shape of the molded article.

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.

A motion transmitting device comprising: a slider movable along a slider guide; and a connecting body movable along a connecting body guide, wherein the slider and the connecting body are disposed in contact with each other, each of the slider and the connecting body has a contact surface that is slidable, and the amount of displacement and/or the speed of displacement of an output end relative to an input end can be reduced or can be made equal to each other or increased through setting of the angle of a center axis line of the slider guide about a center axis line of the connecting body guide and/or the inclination angle of the contact surface.

A method for producing a well or a well strip made of plastic, as used in the pharmaceutical industry in microtiter systems is presented. The wells typically have undercuts and the well strips are connected to each other by connecting ribs. In order to produce a well with a larger undercut height or a well strip with higher connecting ribs, as the case may be, the method provides that the plastic, which is initially still liquid, is pressed through a portion of a runner which is arranged in a slider and out of the slider into a cavity of an injection mold.
