摘要： PURPOSE:To facilitate mounting and removing wires so as to make it possible to suitably cope with a shape in a burr generation part of a core by inserting and holding, into along hole, one end of each wire whose other end is detachably fixed between a wire fixing part and a wire rod fixing jig. CONSTITUTION:A burring tool 10 having therein a rear end of a shaft 1 journalled on a wrist part provided in a robot 15, is turned by a motor 14 provided in this wrist part, while moved by an arm of this robot 15. Thus, the tool 10 rotates wire rods 2 with the axial center of the shaft 1 serving as the center while a total unit of the burring tool 10 is moved, to bring the wire rods 2 into contact with a core A in its burr generation part for performing burring work. Here the wire rod 2, being flexible, corresponds to an arbitrary shape of the burr generation part B, deflecting as shown by a two-dot chain line and smoothly removing burr. While the wire rod 2, being opened to the upper as in a shape of umbrella rib, can remove the burr only by a vertical movement for the hole shape of the burr generation part B.

摘要： PURPOSE:To miniaturize a hydraulic cylinder for die clamp and to reduce an equipment cost. CONSTITUTION:In this die clamping device, the hydraulic cylinder 110 for die clamp working to actuate a die clamping ram 112 and a hydraulic cylinder 130 for die height adjustment coaxially arranged between the die clamping ram 112 and a movable die 124 and adjusting the distance between both 112, 124 are provided. Even if the shifting distance of the movable die 124 varies because of changes of a fixed die 104 and/or the movable die 124, since this variative distance can be absorbed by the hydraulic cylinder 130 for die height adjustment, the working stroke length of the hydraulic cylinder 110 for die clamp can be set to the necessary min. limit value to the die clamp. Therefore, the hydraulic cylinder 110 for die clamp can be miniaturized, and a working oil tank and a hydraulic pump, etc., can be miniaturized.

摘要： PURPOSE:To obtain a fact that a molten metal in a holding furnace becomes below the molten metal waiting holding quantity even if a product whose molten metal consumption is different becomes an object, to contrive the leveling of a molten metal distribution work and to improve the productivity by outputting a molten metal distribution instructing signal so that the molten metal distribution holding time becomes constant. CONSTITUTION:This method uses a molten metal quantity detecting device 6 for detecting the molten metal quantity of a handy holding furnace 2, a setting device 7 for inputting and setting various data, and an arithmetic processing unit 8 which is connected to said molten metal quantity detecting device and executes an operation in accordance with set data of the setting device 7 and detection data of the molten metal quantity detecting device. In this state, the molten metal holding time required for reaching the molten metal waiting from a molten metal distribution instruction is calculated from pouring weight data of a casting product and casting cycle time data. Also, based on this molten metal distribution holding time, the reference molten metal holding quantity is calculated. When the detection quantity by said molten metal quantity detecting device 6 reaches said reference molten metal holding quantity, the molten metal is replenished, by which leveling of the molten metal distribution work is contrived and the productivity can be improved.

摘要： PURPOSE:To discriminate exactly and surely a false casting by measuring the number of shots and the die temp. corresponding thereto and comparing the prescribed number of shots and the reference die temp. CONSTITUTION:A die temp. TD is measured by a temp. sensor, etc. in a die casting machine and the number of shots at the die temp. TD is counted. The temp. TD and the shots N in said stage are compared respectively with the reference temp. and reference number of shots. If either or both of the value TD and number N of shots are below the reference values, said shot is discriminated as the false casting and the signal thereof is outputted as the signal to display the false casting via an OR circuit. If the detected temp. TD is above the reference temp., the detection signal is discriminated as the normal casting via an AND circuit and the prescribed display signal is outputted.

摘要： PURPOSE:To prevent the cast defect in the thick part of a bearing holder in a cylinder block. CONSTITUTION:In a casting device for the cylinder block, recessed parts 14p are formed on the thick part of the bearing holder in the cylinder block and chillers 26 for reducing the thickness of the bearing holder are provided. Then the chiller 26 has the structure, in which the projecting side from the forming surface in a die 13 can be adjusted during casting. For this purpose, the quantity of heat conducted from the molten metal through the thick part of the bearing holder and the chillers 26 is controlled and the solidifying speed of the molten metal in the thick part 14j of the bearing holder is controlled. Therefore, by making the solidifying speed of the molten metal in the thick part 14j of the bearing holder faster than the molten metal in skirt parts 14k of the cylinder block near the runner, the directive solidification is executed and the cast defect is difficult to develop.
