Injection molding machine and control method for injection molding machine
An injection molding machine is equipped with a screw having a spline shaft formed with a spline on an outer circumferential surface, a bush having a spline hole formed with a spline on an inner circumferential surface, a linear motion motor for moving the bush in an axial direction of the screw, a rotational motion motor for rotating the bush about an axis of the screw, and a motor control unit which, in the case of fitting the spline shaft in the spline hole, controls the linear motion motor to advance the bush in a direction approaching the screw in a state that the bush and the screw are separated, and which controls the rotational motion motor to rotate the bush when the acquired output torque becomes equal to or larger than a first predetermined torque.
Injection molding device
An injection molding device has a first mold half, an index plate that in a molding position is at least partly received in the first mold half, and an index plate axle connected with the index plate. The index plate axle is arranged for linear movement along its longitudinal axis relative to the first mold half so that the index plate can be moved between the molding position and a turning position in which the index plate can be rotated with respect to the first mold half. An adaptor plate, connected to the first mold half, has a drive and a first coupling element coupled with the drive. The first coupling element is arranged eccentric with respect to the longitudinal axis of the index plate axle.
Injection molding machine
An injection molding machine includes, on a machine base, a mold having a stationary platen, an injection unit having a nozzle for injecting a molten material into the mold, a nozzle touch mechanism for pressing the nozzle against the mold, and a connecting member for connecting the nozzle touch mechanism and the stationary platen. The connecting member has a support base and an arm part, and also has a first connecting part to be connected to the nozzle touch mechanism on the support base, and a second connecting part to be connected to the stationary platen on an upper part of the arm part. The injection molding machine is configured so that a nozzle touch force is transmitted to the nozzle touch mechanism via the stationary platen and the connecting member. The second connecting part of the connecting member is disposed to be rotatable in a direction along a moving direction of the injection unit.
INJECTION MOLDING MACHINE AND THE MOLDING METHOD THEREOF
An injection molding machine includes an injection apparatus having a screw rotation driving section for rotating a screw inserted to a heat sleeve and a screw forward/rear move driving section for forwardly or rearwardly moving the screw at least by a hydraulic cylinder, including a unique screw for which an L/D ratio between a screw length and a screw diameter is set as a specific value to the injection apparatus. The injection apparatus includes a cylinder attachment mechanism having a cylinder detachable section that provides the detachability of at least two or more different types of hydraulic cylinders adaptable to a molded piece that can be molded by the unique screw.
Toggle mechanism for closing of a mold in a molding machine
According to an aspect of the present invention, there is provided a mechanism for opening, closing, and clamping a mold or die of an injection molding machine comprising: at least two sets of first toggle linkages opposed to each other; at least two sets of second toggle linkages hingedly connected to said first toggle linkages; at least 2 linear activating means for driving the mechanism towards a closed or open position hingedly connected to said second toggle linkages; a movable platen hingedly connected to first toggle linkages for holding an injection molding die, mold, or die casting die; and at least 2 sets of guide rods for the movable platen to slidingly move along its travel path.
FILTER DEVICE
Filter device for a molding machine with at least one filter element for filtering plasticized material, in particular plasticized plastic, wherein, in a fluidically parallel arrangement relative to the at least one filter element, at least one valve element is provided, which is formed to prevent the plasticized material from flowing through the at least one valve element during an injection process in a closed position and to allow the plasticized material to flow through the at least one valve element in an open position, in order to make it possible to relieve the pressure on the at least one filter element after the injection process.
FITNESS MACHINES, HANDLES FOR FITNESS MACHINES, AND METHODS FOR MAKING FITNESS MACHINES AND HANDLES
A method of making a fitness machine. The method includes providing a base device with which an operator may exercise and providing handles each having a non-conductive portion and a conductive portion, the conductive portion being electroplated. The method further includes coupling the handles to the base device so as to be gripped by the operator while exercising and electrically coupling the conductive portion of each of the handles to a control system configured to determine cardiac information for the operator, where the conductive portion of each of the handles receives electrical activity from the operator when gripped, and where the conductive portion is electrically coupled such that the electrical activity is provided to the control system for determining the cardiac information for the operator based thereon.
HOT RUNNER DEVICE HAVING AN OVERLOAD PROTECTION DEVICE
The invention relates to a hot runner device comprising at least one needle valve nozzle and a shut-off needle which is movable in the needle valve nozzle by means of a movement means, and comprising an overload protection device for the shut-off needle, characterized in that the overload protection device is implemented as follows: the shut-off needle is connected in at least a first movement direction directly or indirectly to the movement means by at least one frictional connection that can be released when a threshold force is exceeded.
