Abstract
A kind of fireproof die of cast radiator mainly is made up of top box, nowel, core, stud, cast gate, rising head, steam vent, alignment pin.It is characterized in that top box, nowel make with refractory material, its casting technique does not need founding, and operation is: place core, sand support in top box, nowel; With upper and lower case matched moulds, last alignment pin; Pouring molten iron; Unpack, get foundry goods.Its mould is reusable, has improved work efficiency and product quality greatly, has reduced product cost, has alleviated working strength of workers, has improved sanitary condition, has fundamentally changed casting technique.
Description
The invention belongs to a kind of casting mould and casting technique thereof.
Traditional casting technique must founding.Its main program is to mix molding sand by a certain percentage with sand, bentonite, clay, coal dust, water; Molding sand is put into metal or nonmetal sandbox; Through artificial or mechanical puddling, form upper and lower case; In upper and lower case, put into core, sand support; Upper and lower case is harmonious, locatees by alignment pin; Pouring molten iron then; After cooling, unpack, break up the molding sand in the sandbox; Get foundry goods.
This casting technique has continued the centuries, and the means of production is original, backward, and labor strength is big, and sanitary condition is poor, and environmental pollution is serious, and the operator very easily gets anthraco-silicosis, CO, CO
2Occupational diseases such as poisoning.In process of production, no matter be sand conditioning, still break up molding sand in the sandbox, make all that dust flies upward in the workshop, the air dirt, therefore foundry industry normal and sink into the difficult predicament of advertising for workers.The antiquated sand of having cast is except that a part can be oozed fresh sand recycling, and all the other have just become rubbish to throw away, and each part foundry goods all needs one pair of new sandbox, again founding once, the sandbox cost is about 3 yuan.Can not guarantee product quality with this conventional cast technology, winter is cold, and molding sand is moisture easily to be frozen; Summer heat, moisture content easily evaporation again in the molding sand, the water yield is difficult to control, moisture content is big or little, all occurs waste product easily, the too real or pine too of the compaction rate of molding sand all is prone to sand holes, pit, cavitation erosion incompleteness etc. and forms waste product.
Existing a kind of half mechanical streamline though output increases, but still does not change the substantive issue of founding, but is a machinery and an artificial founding.
The purpose of this invention is to provide a kind of novel die and casting technique made from refractory material, make foundry industry avoid the hardship of founding, improve workman's working condition, improve the quality of products and productivity ratio, and reduce production costs.
The fireproof die of cast radiator of the present invention mainly is made up of top box, nowel, core, stud, cast gate, rising head, steam vent, alignment pin, it is characterized in that: top box, nowel are to make with refractory material, and its refractory material can be one of following material:
(1) electro-corundum sand or alumina ramming mass;
(2) the electric smelting zirconium has just been expected or zirconium pounding rice material;
(3) alumina ramming mass and aluminium oxide refractory matter compound;
(4) zirconium pounding rice material and aluminium oxide refractory matter compound.
The casting technique of cast radiator of the present invention is characterized in that: whole technology does not need founding, and operation is as follows:
A, in top box, nowel, place the support of core, sand;
B, with upper and lower case matched moulds, last alignment pin;
C, pouring molten iron;
D, unpacking gets foundry goods.
The present invention has alleviated working strength of workers greatly, has improved sanitary condition, has fundamentally changed casting technique.
Semipermanent mould of the present invention, its hear resistance can reach 1800 ℃, and molten iron temperature is up to 1300～1450 ℃, therefore can reuse more than 500 times, one pair of mould cost is about 100 yuan, pours into a mould 500 times, the cost of each radiator is 0.20 yuan, is 6% of founding mould.With the mould that has given up, after smashing to pieces, can make refractory brick, therefore, there are not waste disposal and problem of environmental pollution.
With this semipermanent fireproof die, stopped the quality problems that exist in the founding technology, improved 12 times of work efficiency, the recruitment number reduces 3 times.
Fig. 1 is the sectional drawing of one embodiment of the invention.
Fig. 2 is the sectional drawing of another embodiment of the present invention.
Fig. 3 is the organigram of the embodiment of the invention.
As shown in the figure, the fireproof die of cast radiator of the present invention, mainly by top box 3, nowel 5, core 4 or 6, stud 2, cast gate 8, steam vent 9, alignment pin 11 is formed, wherein go up, nowel is to make with refractory material, core 4 or 6 can make circular core or special-shaped core according to difform radiator, because the not of uniform size and technology of radiator is complicated and simple, can be with radiator integral or split casting, for easy to operate, can on mould, be equipped with metal or nonmetal lifting 7, rising head 10, foundary weight 12, mould assembling in the technology, cast, unpacking can be the artificial hand dynamic formula, also can realize with the way of machinery.
