An injection molding temperature control device according to an aspect of the present disclosure controls output of a heater that heats a target site, based on a detection value of a temperature sensor which detects temperature of the target site of an injection molding machine that injects resin into a mold using an injection machine, the injection molding temperature control device including: a temperature control unit which controls output of the heater so as to make the detection value of the temperature sensor approach a predetermined set temperature; a supplied heat amount calculation unit which calculates a supplied heat amount to the target site based on at least one of a drive voltage, a duty ratio and an electrical current value of the heater; and an abnormality detection unit which detects abnormality in temperature control of the target site, based on the detection value of the temperature sensor, and a supplied heat amount calculated by the supplied heat amount calculation unit.

A method of monitoring and controlling a sequential valve gate molding apparatus in an injection molding or other molding process is disclosed. The method includes creating a target strain profile, receiving a deviation limit, receiving a change in strain relating to a first valve gate from a first strain gauge, identifying whether a deviation exists from a first portion of the target strain profile based on the output from the first strain gauge, determining whether any existing deviation exceeds the deviation limit, and adjusting the position of a first valve gate pin in the first valve gate if it does. The method may further include control of subsequent valve gates. Multiple strain gauges may be used to control a single valve gate, and/or each strain gauge may control more than one valve gate.

Method for checking the suitability of a moulding tool for a defined moulding process includes providing an electronic dataset in which each of different features of a moulding tool has a range of possible values; selecting a feature of the electronic dataset as a characterizing feature; establishing an identity of the moulding tool by at least one value of the value range of the characterizing feature, wherein a moulding tool to be checked is regarded as identical to the moulding tool precisely when the established value is present in relation to the characterizing feature; providing an electronic tool dataset including a plurality of different features; allocating the electronic tool dataset to the moulding tool with the established identity by a computing unit; and checking the electronic tool dataset with the computing unit in relation to the suitability of a moulding tool with the established identity in the defined moulding process.

Provided is a mold carrier. The mold carrier comprises a mold bearing chassis, a pressure bearing plate, and a tie bar. The mold bearing chassis includes a plurality of molds disposed therein. Each mold has one or more mold cavities. The pressure bearing plate is configured to physically couple to the mold bearing chassis during an injection molding process. The tie bar runs through the center of the mold bearing chassis and the pressure bearing plate. The mold bearing chassis is configured to allow components to be removed from their molds without separating the mold bearing chassis from the pressure bearing plate.

A sensing module includes a hollow body, a first photo sensor, and a second photo sensor. The hollow body includes a cavity portion and an insertion portion connected to each other. The insertion portion has a first channel and a second channel. The first photo sensor is disposed in the cavity portion of the hollow body and corresponds to the first channel to sense an ambient temperature and a test object temperature. The second photo sensor is disposed in the cavity portion of the hollow body and corresponds to the second channel to sense the ambient temperature.

A controller includes a mold movement control unit that moves a movable mold between a first position separated from a fixed mold and a second position at which mold closing is completed; a determining unit determines the presence of abnormalities in at least one of the movable mold and the fixed mold on the basis of inspection information acquired from at least one of the movable mold and the fixed mold and outputs a confirmation signal related to the presence of abnormalities; and a mold stopping unit that stops movement of the movable mold on the basis of whether the confirmation signal output from the determining unit is acquired while a safety confirmation condition is satisfied after the mold movement control unit starts moving the movable mold from the first position toward the second position.

A casting tool, for example a core shooting tool or a permanent mould, having an upper tool part and a lower tool part, which on opposite sides each have at least one engraving formed as a shell engraving and which form a mould cavity, characterized in that the shell engraving on an outer side facing away from the mould cavity comprises at least one physical sensor which is configured to measure a physical quantity with respect to a material accommodated in the mould cavity. Furthermore, a corresponding casting method is described.

An injection molding tool for producing a molded part and a corresponding method are disclosed. The injection mold tool comprises a first tool mold half and a second tool mold half, which together with a first slider and at least one second slider define a free space for the molded part to be produced. A lever which is pretensioned with an elastic element is assigned to an end switch such that a movable and free end of the lever cooperates with the end switch due to a movement of the first slider.

To provide a method whereby it is possible to easily produce a bonded article in which a member containing a fluorinated polymer and another member are firmly bonded. This method is a method for producing a bonded article in which a member A containing a fluorinated polymer having an adhesive functional group and a member B containing a resin material, are bonded, wherein in a state where at least a portion of the member A (a coating layer 24 and a sheath layer 26 of an electric wire 20) is disposed in the cavity 46 of a mold 40 for injection molding, the resin material is injected into the cavity 46 and solidified to form the member B (connector housing).

An object of the present invention is to provide a technique by which, when producing a resin molded article using an insert member having low pressure resistance, molding can be easily performed, and deformation of the insert member can be suppressed. A method for producing a resin molded article of the present invention, the method includes the steps of disposing an insert member in a cavity of a mold; performing injection of molten resin into the cavity; terminating the injection on and after the molten resin reaches an overflow portion in the cavity and before the molten resin fills the overflow portion; and separating resin in the overflow portion.
