Abstract
The utility model provides a grabbing and releasing device for an inner core of a foundry sand mold, and relates to the field of foundry machinery. The grabbing and releasing device comprises a lifting air cylinder and a grabbing device installed at the lower end of the lifting air cylinder. The grabbing device comprises a sliding plate connected with an extension rod of the lifting air cylinder and arranged horizontally, arc magnetic plates are symmetrically installed on the lower end surface of the sliding plate through sliding blocks in a sliding mode, and iron sheets are uniformly installed at the positions, corresponding to the inner arc surfaces of the arc magnetic plates, in the cylindrical inner core around the radial circumference and are installed close to the outer circle side surface of the inner core. According to the grabbing and releasing device, the iron sheets are placed in the inner core, the inner core can be attracted to be grabbed or released without impacting a cavity through permanent magnets which are electrified and generate magnetism, the efficiency is high, and the qualification rate of products is guaranteed.
Description
Technical field
The utility model relates to foundry machinery equipment field, is specially a kind of fetching device of casting sand mo(u)ld inner core.
Background technology
At industrial casting field, all cast members are all to need fuse to assist to realize complicated Workpiece shaping, now on formative technology streamline, be all to adopt the higher core setter of automatization level to complete, playing exactly core is to be realized by the lowering or hoisting gear of core setter, but how core setter captures and discharge core is more difficult, often between the crawl off-position of core and the die cavity on side, only has the distance of tens millimeters, in crawl and dispose procedure, be easy to encounter the die cavity on side, cause the destruction of die cavity, make product occur underproof situation.
Utility model content
Technical problem to be solved in the utility model is to design a kind of fetching device of casting sand mo(u)ld inner core, utilization is built-in iron plate in inner core, and the permanent magnet by energising magnetisation is held realize to be captured and discharges, and can not encounter die cavity, efficiency is high, has guaranteed the qualification rate of product.
For solving the problems of the technologies described above, the utility model provides a kind of fetching device of casting sand mo(u)ld inner core, comprise lift cylinder, be arranged on the grabbing device of lift cylinder lower end, described grabbing device comprises the horizontally disposed sliding panel that is connected with the extension bar of lift cylinder, the lower surface of this sliding panel is slidably fitted with arc magnetic sheet by slide block symmetry, and the inside of the cylindrical inner core corresponding with the intrados of arc magnetic sheet is evenly provided with iron plate around radial circumference near the position of cylindrical side.
Arc magnetic sheet can produce the permanent magnet in magnetic field for switching on, and after its energising, internally the iron plate of in-core produces attraction, and inner core is firmly held, and after power-off, just nature discharges inner core.
Slide block slides and can adjust two distances between arc magnetic sheet on sliding panel, thereby adapts to the inner core of various sizes size.
As a kind of supplementing of the present utility model, the top of described slide block is embedded in the chute of sliding panel lower surface, between this chute inside, two slide blocks, by spring, be connected, the two ends of described chute are embedded with limited block, in this limited block, be horizontally through the adjusting screw(rod) that has been threaded, withstand with corresponding slide block one end of this adjusting screw(rod), and spring pushes up two slide blocks to both sides, adjusting screw(rod) is withstood with slide block all the time, by rotating adjusting screw(rod), regulate two distances between slide block.
As of the present utility model a kind of preferred, described arc magnetic sheet is the arc plate that central angle is less than 50 degree, and one end of the circular arc cut-off of this arc plate is connected with slide block, arranges like this and can make arc magnetic sheet fully avoid die cavity.
A kind of preferably the iron plate quantity on a circumferential section of described inner core is no less than 8 as of the present utility model, can guarantee arc magnetic sheet all the time with the iron plate effect that is no less than 3, guarantee its attraction.
The utility model utilizes built-in iron plate in inner core, and the permanent magnet by energising magnetisation is held to realize to be captured and discharges, and can not encounter die cavity, and efficiency is high, has guaranteed the qualification rate of product.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further described in detail.
