Description

Sand mold, sand core internal loose piece die drawing device
Technical field
The present invention relates to a kind of sand mold, sand core internal loose piece die drawing device.
Background technology
Casting mould loose piece structure uses in a large number in sand casting, for the loose piece that some structures are special, often because withdrawing pattern frictional resistance is comparatively large, in withdrawing pattern process, causes cast moulding, core damaged, sometimes even causes burn failure because withdrawing pattern method is improper.
At present, the die drawing device of most of sand mold casting mold is all for sandbox or the design of template mould, and the device of mould part of can steadily, easily choosing is also little.The withdrawing pattern method of existing sand mold casting mold loose piece mainly contains following several at (comprising special arrangement or equipment): manually pull out loose piece method, screw rod pulls out loose piece method, drive a vehicle and pull out loose piece method etc.
Artificial withdrawing pattern method is the hand crawl type of operator with oneself, the method for core inner loose piece, and it is only applicable to the loose piece that structure is simple, withdrawing pattern frictional resistance is very little.
It is in mould part, process a screwed hole in advance that screw rod pulls out loose piece method, screws in the withdrawing pattern screw rod of " fourth " font during withdrawing pattern in screwed hole, with hammer jarring loose piece in withdrawing pattern process, and drawing screw rod of outwards exerting oneself on one side.Thisly pull out that loose piece method is applicable to baried type, core has certain depth, the loose piece that withdrawing pattern frictional resistance is moderate, wide in range for the production of.Its advantage is that withdrawing pattern instrument is simple, but deficiency easily damages type, core and mould, and requires that operator has certain withdrawing pattern technical ability.
Driving pull out loose piece method be with common method cannot finishing type, core inner loose piece withdrawing pattern process, just must to finish the work method with a series of hoisting apparatus such as driving, chain sling, suspension hook or equipment.Its advantage is that withdrawing pattern power is large, withdrawing pattern time not need to do all one can jarring loose piece, withdrawing pattern process steady, deficiency is inefficiency, withdrawing pattern direction is had to requirement (vertically upward), equipment use cost is high, and energy consumption is high, also needs driving work coordinating operation in addition.
Summary of the invention
In order to ensure type, the core quality of sand casting moulding and coremaking operation, enhance productivity, avoid the problem of the burn failure because of misoperation pulling, the sand mold can enhanced productivity again while the invention provides a kind of not mold damage, sand core internal loose piece die drawing device.
Sand mold of the present invention, sand core internal loose piece die drawing device, it is characterized in that: comprise bracing frame, lever rotating mechanism, slide block elevating mechanism, described bracing frame comprises guide post and the gripper shoe with internal thread through hole, and described gripper shoe is fixed on the top of described guide post; Described lever rotating mechanism comprises manual rocking handle, rotating screw bolt, and described manual rocking handle is arranged on the upper end of described rotating screw bolt, and the described external screw thread of rotating screw bolt thread segment mates with the internal thread of gripper shoe; Described slide block elevating mechanism comprises socket slide block on the guide bar, for being placed on the pressure regulator between slide block and sand mold or core, described slide block bottom surface is with the projection to lower process.
Described bracing frame is portal frame type structure, and each bracing frame is furnished with two and is parallel to each other and the guide post vertical with gripper shoe.
The bottom of each guide post all fix one with the locking pin of guide post axes normal, and two locking pins are positioned in same level, and the direction of advance of this locking pin is pointed in the front end of each described locking pin.
Described rotating screw bolt upper side has the jack for inserting manual rocking handle, and described rotating screw bolt is vertical with described manual rocking handle.
Be provided with groove with the slide block upper surface described in the contact of rotating screw bolt end, and described groove is positioned at directly over described projection.
Described pressure regulator be according to sand mold during withdrawing pattern or core can the pressure adjustable plate that makes of Area of bearing.
Use step is as follows: (1) preparation:
A, in advance drill two holes in mould part, the size in hole and distance will manufacture with two of a die drawing device locking pin;
B, according to sand mold during withdrawing pattern or core can Area of bearing, make pressure regulator, to reduce to act on the pressure on sand mold, core;
(2) prepared mould part: after the sand mold made, the core demoulding, pressure regulator has been placed on the die drawing device supporting surface of sand mold, core, then die drawing device has been placed on sand mold, core;
(3) locking die loose piece: two locking pins are screwed in two withdrawing pattern holes on loose piece, turns clockwise die drawing device to can not rotating;
(4) mould part is pulled out: rotate clockwise manual rocking handle, rotating screw bolt rotates and moves downward, screw rod lower surface promotes slide block and holds out against pressure adjustable plate, and under the effect of sand mold, the reverse support force of core, two locking pins upwards extract mould part in sand mold, core;
(5) moving-out device and loose piece: after loose piece is extracted, moving-out device and loose piece;
(6) unload loose piece: rotate counterclockwise die drawing device, unload loose piece from locking pin, and take off pressure regulator from type, core, pull out loose piece work and complete.
The invention has the beneficial effects as follows: loose piece die drawing device is chosen loose piece, loose piece uniform force, to choose steadily, do not damage sand mold, core and mould, fully meet loose piece and to choose process quality requirement; Operator just can produce very large extraction force to the loose piece of type, in-core by less power, is easy to manual operations; Loose piece die drawing device has that production efficiency is high, small investment, the superiority of assisting without the need to ancillary staff.
