Multi-layer injection molded container
A method for manufacturing an injection molded container includes operating an injection molding apparatus to inject one or more polymeric materials into a mold cavity to form a container. The container includes an energy director ring protruding from an inside surface of the container and extending circumferentially along the inside surface. The method includes welding a filter onto the inside surface by applying a welding force to the inside surface. The energy director ring causes the welding force to be concentrated at a location of the energy director ring, thereby forming a circumferential weld that secures the filter to the inside surface the location of the energy director ring.
INJECTION MOLDING MOLD
The present invention pertains to an injection molding mold that can extrude the entirety of a workpiece from a cavity even when the cavity is enlarged so as to extend further than the outer side of an ejector plate. The injection molding mold may include a mold member having a cavity formed on the front side, a mold frame supporting the mold member from the back side, an ejector plate provided in the space within the mold frame so as to ascend and descend freely therein, a first workpiece extrusion means for extruding the workpiece above the ejector plate, and a second workpiece extrusion means for operating in conjunction with the first workpiece extrusion means and extruding the workpiece formed in the cavity in an area that is further to an outer side than the ejector plate.
INJECTION MOLD
An injection mold comprising a first mold half and a second mold half which during operation are displaceable with respect to each other in a first direction between an open position and a closed position in which the first mold half and the second mold half interact with each other. The first mold half comprises a cavity plate with a front face with a recess in which at least one cavity block comprising at least one first cavity half is arranged forming in a closed position of the injection mold with a corresponding second cavity half arranged at the second mold half a cavity suitable to receive plasticized plastic material to form a part therefrom. At least one cable interconnects the at least one cavity block in a mounted position with a connection box.
Machine tool
An injection molding machine according to the present invention is a machine tool that includes a measurement unit that measures a predetermined measured value; a calculation unit that calculates attitude accuracy information about the injection molding machine based on the measured value measured by the measurement unit; and a display that displays the attitude accuracy information calculated by the calculation unit together with an overhead view of the injection molding machine.
CONTROLLER ARRANGEMENT FOR INJECTION MOLDING SYSTEM
An injection molding apparatus (10) comprising a signal converter (1500) interconnected to a machine controller (MC) of an injection molding machine (IMM) that generates standardized signals (VPS), the signal converter (1500) receiving and converting the standardized signals (VS) to a command signal (MOPCS, PDCVS) that is compatible with a signal receptor or interface of an electrically powered actuator (940e, 941e, 942e) or a signal receptor, interface or driver of a proportional directional control valve (V, V1, V2) that drives a fluid driven actuator (940p, 941p, 942p) to respectively operate the electrically powered actuator (940e, 941e, 942e) or the proportional directional control valve (V, V1, V2) to move in a direction that operates to either begin an injection cycle and to end an injection cycle.
PROGRAMMING A PROTECTION DEVICE FOR A MOLDING MACHINE
A system for programming a protection device for a molding machine includes a controller for actuating a plurality of molding machine actuators in an actuation sequence, each distinct actuation constituting a respective machine component actuation of an associated machine component. An HMI is operable to: present a GUI specific to a chosen machine component actuation; and for each of a plurality of other machine component actuations, define within the GUI, based on operator input, a rule specifying a state of the chosen machine component actuation relative to a state of the other machine component actuation for preventing interference between the two machine component actuations. The controller is configured, based on the rules defined within the GUI, to trigger an action, upon violation of any one of the rules, for reducing a risk of interference between the chosen machine component actuation and a respective one of the other machine component actuations.
SYSTEM FOR CONTROLLING A SHUTTER OF A PLASTICS INJECTION SYSTEM
The invention relates to a system for controlling a shutter arranged to slide in a plastic material injection nozzle, comprising: a hydraulic or pneumatic actuating cylinder (1) coupled to said shutter to make it slide between a shutting off position of the nozzle and a maximum opening position of the nozzle, a device (2) for controlling the actuating cylinder (1), comprising at least two elements among: an element adapted to regulate the stroke of the actuating cylinder to a first constant speed, an element adapted to regulate the stroke of the actuating cylinder to a second constant speed, greater than the first speed, an element adapted to selectively block the stroke of the actuating cylinder, a sequential control unit comprising at least two control paths (30, 31, 32) configured to send selectively an electrical control signal to the device (2) via one and/or the other of said control paths (30, 31, 32) such that: under the effect of a first signal sent via the first control path (30), one of the elements is activated, under the effect of a second signal sent via the second control path (31), another element is activated.
Injection molding system
In order to calculate a ball screw abrasion amount of an injection-axis ball screw or a mold-clamping-axis ball screw, a position of a ball nut fitted to the ball screw is photographed by a camera installed in an injection molding machine. Then, if the photographed position of the ball nut is found, as a result of analysis of an image captured by the camera, to be deviated from the position of the ball nut when a ball screw has no abrasion, it is determined that the ball screw is abraded.
CONTROL METHOD AND DRIVE CONTROL APPARATUS OF HYDRAULIC INJECTION MOLDING MACHINE
When the deceleration start point is reached, the meter-in side of the hydraulic driving actuator is subjected to a flow rate control to thereby start the deceleration control processing. The position to which the movable unit is moved is detected to use a speed instruction corresponding to the movement position to subject the hydraulic driving actuator to a meter-in control. The position to which the movable unit is moved is detected to calculate the moving speed of the movable unit. Based on the speed instruction, the moving speed is subjected to the feedback control using the meter-out control to the hydraulic driving actuator.
Abnormality detection device
An abnormality detection device for detecting an abnormality of a movable part provided in an injection molding machine includes: a through hole formed in the movable part or in an adjacent member arranged adjacent to the movable part; and a microphone installed inside the through hole to collect sound generated by the movement of the movable part.
