摘要： PURPOSE:To reduce the inclusion of a coating metal in the melt base metal at the time of removing the coating metal from a metallic piece formed by plating the surface of a base metal with the coating metal having a lower m.p. than the base metal. CONSTITUTION:A coating metal is separated from a metallic piece 4 formed by plating the surface of a base metal with the coating metal having a lower m.p. than the base metal. In this case, the piece 4 is placed in a heating furnace 7 and uniformly and directly heated in a reducing atmosphere by the combustion flame at a temp. higher than the m.p. of the coating metal and lower than that of the base metal to vaporize the coating metal from the piece 4, and the vaporized coating metal is discharged outside the furnace along with the waste combustion gas.

摘要： PURPOSE: To remove molding sand thoroughly from castings and supply the castings a constant posture to the next process by treating the castings cast in vertically split flaskless type molds with a sand cutting device, a suspension supporting device by clamps and a knock-out device while moving these continuously.
CONSTITUTION: A large number of continuous cast molds 1 which cast molten metal in molds of a vertically split flaskless system and are fed in a direction A by a mold feeder 2 are solidified during conveying and in this state, they are fed to the position of a sand ductting device 23. The pawls 26 of the device 23 are inserted into the top surface and upper both sides of the molds reiteratively, by which some parts 27 are cut of sand to expose shoulder parts 3. The parts 3 are supported with bars 19, and when they come to a prescribed position, air cylinders 14, 17 advance so that clamps 13, 18 apply restraining under pressure grasping to the parts 3 and the molds 1 from both sides; at the same time, the speed of the clamp 18 is made faster than that of the 13 to cut the remained molding sand completely owing to the differences in their relative speeds. In the constant posture, the castings are shifted to the next processes of ingate breaking, etc., whereby the working efficiency is improved.

摘要翻译：目的：从铸件中彻底清除模型砂，并通过用砂光切割装置处理垂直分割的无盖式模具铸造的铸件，通过夹具和拆卸装置对悬架支撑装置进行处理，向下一个工序提供恒定的姿势，同时不断移动这些构成：大量连铸铸模1在垂直分割的无棚系统的模具中铸造熔融金属，并通过模具供给器2在方向A上进料，在输送过程中固化，在这种状态下，它们被送入砂管道装置23.装置23的爪26重复地插入模具的上表面和上两侧，由此一些部分27被切割以暴露肩部3。部件3由杆支撑如图19所示，当它们到达规定位置时，气缸14,17前进，使得夹具13,18在两侧的压力抓持下对部件3和模具1施加约束; 同时，由于其相对速度的差异，夹具18的速度比13的速度更快地切割剩余的模型砂。在恒定的姿势下，铸件被转移到下一个进料断裂过程等，从而提高了工作效率。

摘要： PURPOSE:To reduce equipment cost and to improve the quality of a product by providing 1st and 2nd transfer devices in series on a mold transfer device and operating the 1st transfer device intermittently. CONSTITUTION:From a mold carry-in side 1st transfer device 1 and 2nd transfer device 9 are arranged in series in order, a visual sensor 5 is set up at the upper part of the abutting branch point 3 thereof and further an encoder 6 at the lower part of the device 1. A mold 4 is fed by the 1st transfer device 1 and a driving part 8 is stopped at the time when the reading distance (l) of the sensor 5 and the feeding amt. X of the encoder 6 coincide therewith. At this time the butt face (a) of the mold 4 coincides with the branch point 3 and the mold 4 is separated to both sides at a point (a). When the 1st transfer device 1 is then moved, a product 12 is delivered to the 2nd transfer device 9 in an exposed state and the cooling is quickly executed. Due to the cooling speed of the product 12 being quickened, the length of the transfer device is contracted and the equipment cost is reduced. Moreover the product quality is also improved.

摘要： PROBLEM TO BE SOLVED: To improve production efficiency by a casting method which can lighten a cover and, perform cover mounting/dismounting securely and safely with a device of simple structure, mechanically stable and of convenient one. SOLUTION: This centrifugal casting die cover mounting/dismounting mechanism 1 is equipped with locking parts 3 installed at one end opening 2 side, and a centrifugal casting die 9 having a casting die cover 8 wherein a guide shaft, a cover part 5 mounted to the guide shaft, a slide member being installed reciprocatory along an axial direction of the guide shaft 4, a cover mount/ dismount member which is lockable with the locking parts 3 by engaging with the slide member accompanying reciprocation move of the slide member, and released from a caught condition with the stopping part are provided. Furthermore, the mechanism 1 is equipped with the slide member grasping part 10 which can grasp the slide member 6 of the die cover 8 and, a cover mount/ dismount device having a reciprocation means 11 for making the slide member grasping part 10 reciprocatable along an axial direction of the guide shaft.
