Description
Technical field
The present invention relates to a kind of method and a kind of sand molding machine of penetrating that is used to make the casting core of the mold that profiled member such as casting metal melts use.
Background technology
In traditional manufacturing of the casting core of determining for casting light metal melt, a kind of common molding material with synthetic resin-bound is injected in the cavity of net shape of casting core profiled member definite to be produced of mould.Wherein in order to inject cavity equably, mould has the injection orifice of sufficient amount, injects molding material by these holes.In order to fill in mould, each one " injection nozzle " inserts in each of these injection orifices, borrows its injection molding material then.Each injection nozzle is general common to be carried by one adjustable for height " injection top board ", and the latter guarantees core case turnover injection position.
In known devices, realize the feed of injection nozzle usually via a what is called " injection shield ", this injection shield covers the injection top board and injects molding material in the one side away from mould of injection top board.
In order to inject molding sand, the molding material that is contained in the injection shield rapidly is subjected to a kind of gas equably, is generally the pressure of air by an injection cylinder, thereby it is driven in the mould by injection nozzle.In order to make profiled member to be made form required final strength, have such possibility on the one hand, promptly, in molding material, cause the chemical reaction of catalysis by adding proper additive.In this so-called " cooler bin method ", because chemical reaction obtains the profiled member of a sclerosis.But it no longer can be led in the circulation of the material that is back to the profiled member manufacturing.
Perhaps, when adopting the adhesive that is fit to, can harden by heating starting.In order to implement this what is called " hot case method ", the sand molding machine of penetrating of known manufacturing core is equipped with heater in order to heating mould.Realize the sclerosis of profiled member in this case by the heating in mould.
Because the employing of organic bond can cause the burden of workplace and environment, people make every effort to replace being used to so far make the molding material that comprises organic bond that casting core adopts with such molding material, it is by inorganic bond, for example adhesives of waterglass base.A kind of method, it can make the molding material of such composition be used for the manufacturing of core members, and it is known testing chamber 0 917499 B1 by EP.
According to this known method, at first mixing of adhesive make a molding material by an inorganic fire-resistant molding sand and an inorganic waterglass base.Then with in this molding material implantation temperature mould controlled, that in injection process, be subjected to suction function.Wherein be adjusted to make and on core members, form a shell dimensionally stable and that bearing capacity is arranged in later temperature/time of staying of closing molding with molding material.If core members has reached this state, then open mould and take out core members.It is dry completely that core members is obtained under the effect of microwave.Eliminate moisture with physical method from the molding material that constitutes owing to the mixture that injects mould thus.As a result, even still also can reach the sclerosis of core members by such dehydration in mould, this makes it can handle in the procedure of processing that continues at least.
Implementing to demonstrate various shortcomings in the known method with the equipment of traditional device that is equipped with heating mould in practice.This shows as for example undesirable too early sclerosis of molding material in the member of penetrating the sand molding machine, and this is interpreted as owing to caused by the heat of mould radiation.Be particularly related to injection nozzle and injection shield in these members, even they also are heated to molding material because the critical-temperature that dehydration begins to harden at holding fix.The too early sclerosis of molding material causes for example forming at the lip-deep sclerderm of molding material in injection shield, thereby molding material no longer can be imported in the mould in accordance with regulations.Consequence be mould not exclusively fill with obstruction with injection nozzle.The molding material of sclerosis causes the obstruction of nozzle equally in injection nozzle itself, thereby also no longer can guarantee uniformly filling in accordance with regulations.
Summary of the invention
The objective of the invention is to, a kind of method and apparatus is provided, whereby can be reliably and the profiled member of using with the easy fault manufacturing mold that reduces by the molding material that comprises inorganic bond.
From above-described prior art, this purpose at first reaches by a kind of method that is used to make the profiled member of the mold that casting metal melts uses.This method comprises:
-penetrate in the sand molding machine at one, by means of injection element such as injection nozzle and injection shield, with a kind of molding material that comprises inorganic bond be injected into a mould determine wait to make in the cavity of profiled member shape;
-in a firm time, to the molding material heat supply of injecting mould, so that make the molding material sclerosis by the elimination of moisture; And
-between hardening period, make at least penetrate comprising of sand molding machine molding material, that between this hardening period, be in holding fix, be subjected to follow the injection element of heating to remain on a temperature levels that prevents profiled member sclerosis by the radiant heat that mould sends.
Secondly, reach by a kind of sand molding machine of penetrating that is used to make the profiled member of the mold that the casting light metal material uses, this is penetrated the sand molding machine and comprises:
-one mould, this mould has the cavity of determining to wait to make the profiled member shape;
-one heater is in order to heating mould;
-a plurality of injection elements, in order to molding material is input in the mould, wherein mould can move on to a holding fix with respect to injection element and/or injection element from an injection phase with respect to mould, in the injection phase, they closely are adjacent to be provided with, so that fill in mould, and at holding fix, they are located away from each other; And
-one humidifying device, this humidifying device make these contain molding sand when injection element is in holding fix and the injection element that is positioned at the radiation of heat zone of sending by mould to keep being moist.
Can also withdraw between the station at an injection station and in this situation preferred mold and to move around.
Be specially adapted to make the casting core that casting light metal melt is used according to method of the present invention with according to the sand molding machine of penetrating of the present invention, it has represented the overwhelming majority of the mold spare of making in the device of the pattern of being considered in practice here.
According to the present invention, it is moist keeping these members targetedly between the hardening period of the molding material that injects heated mold, the heat that they are given off by mould is heated to a temperature, may cause the sclerosis not inadvertently too early and that therefore disturb of molding material under this temperature.Resist in such a way in these members or on it otherwise since heating the dehydration of molding material can take place and prevent that thus molding material from penetrating the sclerosis in these crucial members of sand molding machine.Each member that is added heat affecting in this case especially typically relates to injection nozzle or gives the needed injection shield of injection nozzle and go up the injection plate that connects or the feed path of other guiding molding material for feed.
By for required retention period of the sclerosis of profiled member in mould these members of humidification targetedly, for example prevent that sclerderm in the injection shield not only forms but also injection nozzle stops up because of the molding material of sclerosis.Also the molding material that comprises the adhesive of inorganic waterglass base can be used for the profiled member that casting operation is used reliably in such a way.The feature of the profiled member that obtains is in the circulation of good intensity and the material that can lead back profiled member manufacturing employing after it uses again.
Therefore what the heat that is sent by mould heated also can realize according to first scheme of the present invention at the humidification of member compromised aspect the sclerosis of molding material like this, even at least one injection element at least temporarily is subjected to the effect of humid atmosphere between hardening period.This form of implementation of the present invention is particularly suitable for avoiding the sclerosis of molding material in injection nozzle when keeping the atmosphere of humidity targetedly in cover.Wherein the water content that preferably forms the atmosphere of carrier gas by air is suitable for corresponding situation.Like this, for example can imagine, will become to make the sclerosis that on injection nozzle, forms condensate liquid and therefore avoid being contained in molding material in the injection nozzle or that adhere on it reliably around the humidity regulation of the atmosphere of the injection nozzle that is in holding fix.
Selectively or be complemented at by keep one the regulation humidity atmosphere humidification maybe advantageously, make at least one injection element of following heating between hardening period at least temporarily the cooling.Can cause the formation of condensate liquid equally by such cooling targetedly.Therefore this form of implementation of the present invention is particularly suitable for protecting the obstruction of the molding material that injection nozzle avoids hardening.To inject the humidification of air own in addition or selectively, so that prevent the dry and sclerosis of molding material from the beginning.
Of the present invention another is easy to realize especially and still effectively form of implementation is characterised in that, at least one injection element of following heating was at least temporarily contacted with a moisture carrier between hardening period.This moisture carrier can relate to the particularly absorbent material crossed of water retting of a usefulness liquid, as sponge or rag.Actual experiment proves, when such moisture carrier leans against on the injection nozzle that is in holding fix, can avoid being contained in the sclerosis of the molding material in the nozzle reliably.
By between hardening period at least temporarily by a kind of hot gas, the cavity of the air flow through molds of preferred heating makes this gas import and carry full water dryly and divides ground to discharge, and can improve the hardening process that is contained in the profiled member in the mould targetedly.In this case mould fill with after the molding material during the needed time of hardening for profiled member except import via mould itself hot also the air-flow of the drying of a heat is led the overmolding part.From mould, discharge the gas that in hardening process, takes place in such a way on the one hand.In the hot molding part that will add on the other hand.This heat is not to enter its inside via the shell of profiled member lentamente in this case, but by apace by the core inside of air-flow molding part.
As a result, reach Rapid and uniform core hardening thus.Also will make the influence of varied in thickness of the surging of core reduce to minimum thus.Therefore the profiled member that obtains according to this scheme of method of the present invention has had extra high equally distributed intensity when taking out from mould.Simultaneously in such a way for example when making the casting core rod accessible circulation timei be not higher than by comprising organic bond, particularly the needed time of core rod is cast in the molding material manufacturing of synthetic resin accordingly.
