Abstract: An injection device of a die casting machine including an injecting cylinder, in which a piston connecting to a piston rod is slidably thrust into a cylinder body and in which pressurized oil is fed to the side of the piston from a pressurized oil source and flows out from the side of the piston rod, and a servo valve controlling an injection speed of the injection cylinder device by controlling the amount of flow of pressurized oil that flows out from the injecting cylinder. The servo valve is directly attached to the cylinder body of the injecting cylinder and a flow channel connecting the injecting cylinder and servo valve is shortened.

Abstract: A method and an apparatus of controlling the injection of a die casting machine can be used for any existing metal molds without requiring the use of a metal charge front sensor and shift the speed of advancement of the plunger rod to initiate a forced speed reduction of the plunger at a right timing regardless of variances in the charge of molten metal so that the machine may stably produce quality die cast products. Such a method of controlling the injection of a die casting machine for injecting molten metal fed to an injection sleeve into a metal mold by means of an injection plunger 100 to charge the metal mold with molten metal comprises the steps of detecting the pressure of the plunger rod charging the metal mold with molten metal; determining that the molten metal has arrived the gate section, or injection port, of the metal mold at a time when the detected pressure gets to a predetermined value; and controlling the injection speed on the basis of the time.

Abstract: A stroke S of a squeeze pin under no load condition of a squeeze pin cylinder for driving the squeeze pin is detected. A value (S-.alpha.) obtained by subtracting a small value .alpha. from the detected stroke S of the squeeze pin is determined as a set stroke of the squeeze pin. After a predetermined waiting time has elapsed from when melted metal is charged into a cavity completely, the squeeze pin is advanced. Here, the actual stroke Sf of the squeeze pin is detected, and the detected stroke Sf is compared with set stroke (S-.alpha..+-..beta.), where .beta. is an allowable deflection. As the result of comparison, if Sf oversteps the set limits (S-.alpha..+-..beta.), at least one of parameters (the pressure and the flow rate of hydraulic fluid supplied to the squeeze pin cylinder and the waiting time) is corrected, so that the detected stroke value Sf approaches the set stroke (S-.alpha.) for the succeeding casting cycle.

Abstract: An apparatus for displaying casting-data in a die-cast machine having a plurality of sensors which gather data values such as speed, pressure and temperature. A converter processes signals from sensors, and an input-calibration mechanism may be provided for correcting the processed signals and for issuing detected data. A casting-cycle data processing mechanism may be provided for displaying data items such as an injection speed or an injection pressure every casting cycle, based on the detected data. A casting control data processing mechanism may also be provided for displaying shot-time items and fluctuations through repeated injection cycles to monitor casting operation, where displays are based on the detected data from the input-calibration mechanism.

Abstract: A stroke-end position of an injection cylinder of the die cast machine is detected and a position of the injection cylinder for sending a boosting-signal is set. This position is a predetermined standard boost stroke distance from the stroke-end position. When the injection cylinder reaches the position for sending the boosting-signal in the casting cycle, an oil-pressure intensifier is advanced. In this method, before casting is performed, a value representing a stroke after slowing-down and a setting value of the plunger stopping position are determined and the start point for slowing-down is calculated by subtracting the value of the stroke after slowing down from the setting value.

Abstract: In a press casting machine a molten material enclosed in a cavity of a mold is squeezed by a pressure pin, the pressure pin is controlled by automatically controlling the start timing thereof. Namely, an optimum stroke of the pressure pin is preliminarily set and an actual stroke thereof is detected. The detected stroke of the pressure pin is compared with the optimum stroke thereof and a start timing of the pressure pin is corrected or modified so that the stroke thereof is made optimum. When the detected stroke of the pressure pin is smaller than the set stroke thereof, the start timing of the pressure pin is corrected so that a timing for starting the pressure pin advances and, on the contrary, when the detected stroke of the pressure pin is larger than the set stroke thereof, the start timing of the pressure pin is corrected so that a timing for starting the pressure pin is delayed.

Abstract: In production of a gap spacer for magnetic heads in electric and electronic appliances, accumulation of a non-magnetic material insoluble to acids or alkalis on a thin base soluble to these solvents is employed with use of a proper mask as a substitute for the conventional rolling process. Stable growth in thickness of the non-magnetic material during the accumulation process assures highly precise thickness uniformity of the product via easy time control of the process and absence of the rolling process allows broader freedom in choice of the material.

Abstract: In a metal-insulator alternate type multilayer head core usable for magnetic sound recording and reproducing, metallic component layers are connected to each other via one or more metallic interconnecting layers passing locally through insulating component layers in order to provide high effective permeability with minimized eddy current loss. In manufacturing, a metal-insulator alternate type multilayer construction including the metallic interconnecting layer or layers is subjected to sintering in order to avoid intermetal separation which might be otherwise caused by cracking in the insulating layers.
