Abstract
The utility model relates to a mold core filler and belongs to the technical field of casting. The mold core filler comprises a pop-top can and a sealing piece, wherein the sealing piece fixedly seals an opening on the top of pop-top can; the outer part of the pop-top can is provided with vent holes; one or more vent holes are formed on the outer side of the pop-top can and are distributed on the circumference of the pop-top can; the diameter of the vent holes does not exceed 1mm; and the sealing piece has an area larger than that of the opening on the top of the pop-top can and has the thickness of 0.2-1.2mm. The manufactured mold core has light weight, high strength at room temperature, high high-temperature refractoriness, high air permeability and high deformability; moreover, the used sand is easily separated from the pop-top can, a regeneration effect of the used sand is improved, and the using amount of fresh sand is saved; and therefore, the production cost is reduced. The reformed pop-top can which serves as the mold core filler can be recycled. After being repeatedly used, the sorted pop-top can which cannot serve as the mold core filler can serve as scrap metal to be remelted, so the cost of the reformed pop-top can which serves as the mold core filler is greatly reduced.
Description
Technical field
The utility model relates to a kind of core filler, belongs to casting technology field.
Background technology
At present, domestic when producing heavy castings, have preferably gas permeability with deformability and save a large amount of fresh sands, big core inner general adopt coke, slag or the filling of old sand piece in order to make core.When casting falling sand, cleaning, old sand and coke or slag are blended in one, are difficult to separate, and have both influenced the performance of reclaimed sand, have also increased difficulty and cost that core sand regeneration is reclaimed simultaneously.Especially using resin sand to produce foundry goods, under the quality requirement condition with higher to reclaimed sand,, also can increase the castings production cost if old sand recycling well not only reduces the core serviceability.
The recovery and utilization technology of discarded pop can is a little less than China's development.The general employing sorted remelting.Directly the shared ratio of recycling manufacturing articles is little.Patent CN1325004 discloses with waste top-pop, plastic bottle-made solar energy clothes rack water heater method.Patent CN1045556 discloses the method for making clip art with waste and old easy open can.Patent CN1069333 discloses the heat exchanger means made from discarded pop can.CN2274561 discloses with waste and old pop can perlite insulating brick method.But the discarded application of pop can on foundry engieering also do not appear in the newspapers.
Discarded pop can, hollow, wall approach, and certain intensity is arranged under the normal temperature; Yielding under the high temperature, suitable refractoriness is arranged, have deformability preferably.Relative molding sand, discarded pop can volume is big, in light weight, and simple screening can separate with molding sand easily.If use iron pop can, on the regenerating used production line, adopt existing magnetic plant, also separate with molding sand easily.The discarded pop can of the transformation of the way is used for making the core filler, and the problem that can solve general core filler pollution molding sand is recycled the new approach that provides for discarded pop can again.
Summary of the invention
The purpose of the utility model provides a kind of core filler, pollutes molding sand to solve general core filler, recycles difficult problem.
The technical scheme of the utility model is: the pop can to discarded is changed a social system processing.Pop can with after the transformation of the way uses as the core filler.
A kind of core filler comprises pop can 1 and diaphragm seal 3, and diaphragm seal 3 fixing seals are on the opening on pop can 1 top, and pop can 1 outside is provided with passage 4.
Said pop can 1 outside passage 4 can be one or more, is distributed in the pop can whole body.
The diameter of said passage 4 is no more than 1mm.
Said diaphragm seal 3 areas are greater than the aperture area on pop can 1 top, and its thickness is 0.2～1.2mm, and are fixing through rivet 2.
The size of the described diaphragm seal 3 of the utility model is confirmed according to actual needs, as long as be not less than the opening of pop can 1.Said sealing and fixing mode is except fixing through rivet 2, and sealing and fixing method commonly used in the industry is all suitable, like connected modes such as welding, bondings.
During coremaking, the pop can that the transformation of the way is good is put into the middle part of core, around the arbor, replaces original core filler.After casting falling sand, the cleaning, use magnetic separation and screening plant, separate old sand and pop can.The old sand recycling, the pop can of separation sorts.Sorting out the intact pop can of shape then can continue to recycle as the core filler.Sort out shrivel or opening bigger, can not remake the pop can that uses into the core filler, can be used as old metal and reclaim remelting.
The utility model is changed a social system processing to discarded pop can, the steps include:
(1) the discarded pop can of letter sorting.Require discarded pop can be do not have compacting, be preferably pop can made of iron.
(2) surface of pop can is handled.Remove the ply of paper or the baking vanish on pop can surface, to reduce the gas forming amount of core in the casting and pouring process.
(2) seal up the opening of cover of pop can with diaphragm seal.When preventing coremaking, core sand gets into from the opening part of cover of pop can.
(4) beat air-vent all over the body at pop can, the diameter in hole is less than or equal to 1mm, to increase its gas permeability.
The beneficial effect of the utility model is: the pop can of the transformation of the way as the core filler can make the core of manufacturing in light weight, normal temperature strength is high; High-temperature flame-proof degree, gas permeability and deformability are good; And easily old sand is separated with pop can; Improve the regenerating used effect, thereby the consumption of having saved fresh sand has greatly reduced production cost.The core filler of the pop can conduct of the transformation of the way can use repeatedly; After repeatedly using sort out can not conduct the pop can of core filler still can be used as old metal and sell the salvage station and send steel plant's remelting, therefore greatly reduce the cost of the core filler of transformation of the way pop can conduct.
