Description
Technical field
The utility model relates to a kind of sand mold, the inner loose piece die drawing device of core.
Background technology
Casting mould loose piece structure is used in a large number in sand casting, for the special loose piece of some structures, often because withdrawing pattern frictional resistance is larger, in withdrawing pattern process, causes cast moulding, core breakage, sometimes even causes because withdrawing pattern method is improper that mould damages.
At present, the die drawing device of most of sand mold casting molds is all for sandbox or the design of template mould, and the device of the 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 that loose piece method, screw rod are pulled out loose piece method, loose piece method etc. is pulled out in driving.
Artificial withdrawing pattern method is the hand crawl type of operator's use oneself, the method for core inner loose piece, and it is only applicable to loose piece simple in structure, withdrawing pattern frictional resistance is very little.
It is in mould part, to process in advance a screwed hole that screw rod pulls out loose piece method, screws in the withdrawing pattern screw rod of " fourth " font when withdrawing pattern in screwed hole, uses hammer jarring loose piece in withdrawing pattern process on one side, the 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 is easily to damage type, core and mould, and requires operator to have certain withdrawing pattern technical ability.
Driving pull out loose piece method be with common method cannot finishing type, the loose piece withdrawing pattern process of core inner, must be by a series of hoisting apparatus such as driving, chain sling, suspension hook or the equipment method of just finishing the work.Its advantage is that withdrawing pattern power is large, it is steady not need to do all one can jarring loose piece, withdrawing pattern process when withdrawing pattern, and deficiency is inefficiency, has requirement (vertically upward), equipment use cost high to withdrawing pattern direction, and energy consumption is high, also needs in addition the work coordinating operation of driving a vehicle.
Summary of the invention
In order to guarantee type, the core quality of sand casting moulding and coremaking operation, enhance productivity, avoid the problem of damaging because of the mould of misoperation pulling, the sand mold that can enhance productivity again when the utility model provides a kind of not mold damage, the inner loose piece die drawing device of core.
Sand mold described in the utility model, the inner loose piece die drawing device of core, 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 and the internal thread of gripper shoe mate; Described slide block elevating mechanism comprises the slide block that is socketed on guide post, for being placed on the pressure adjusting device 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.
A locking pin vertical with guide post axis is all fixed in the bottom of each guide post, and two locking pins are positioned in same level, and the front end of each described locking pin points to the direction of advance of this 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 described slide block upper surface contacting of rotating screw bolt end, and described groove is positioned at directly over described projection.
Described pressure adjusting device is the pressure adjustable plate of can Area of bearing making of sand mold or core during according to withdrawing pattern.
Use step is as follows: (1) preparation:
A, in mould part, bore two holes in advance, size and the distance in hole will manufacture with two of a die drawing device locking pin;
B, during according to withdrawing pattern sand mold or core can Area of bearing, make pressure adjusting device, to reduce to act on the pressure on sand mold, core;
(2) prepared mould part: after the sand mold made, the core demoulding, pressure adjusting device is placed on the die drawing device supporting surface of sand mold, core, then die drawing device is placed on sand mold, core;
(3) locking die loose piece: two locking pins are screwed in two withdrawing pattern holes on loose piece, till the die drawing device that turns clockwise extremely can not rotate;
(4) pull out mould part: clockwise rotate 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 are upwards extracted 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 adjusting device from type, core, pull out loose piece work and complete.
The beneficial effects of the utility model are: the loose piece die drawing device loose piece of choosing, and loose piece is stressed evenly, choose steadily, do not damage sand mold, core and mould, fully meets the loose piece process quality requirement of choosing; 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 ancillary staff.
