Abstract
The invention discloses a kind of hot water dewaxing's techniques of low-temperature wax mould material sodium silicate shell, include the following steps：Heating water and prepare dewaxing liquid, remove floating sand, mould group enters slot, mould group goes out slot, flushing, swabbing.The present invention in hot water by being added dewaxing liquid, it is under the cooperation of dewaxing liquid and hot water that wax fusing removing is clean, by the way that mould group is put into hanging basket, the lifting of hanging basket is controlled by electronic mode again to carry out control mould group disengaging dewaxing slot, it avoids people directly to contact with dewaxing slot, personnel is prevented to be burned.
Description
Technical field
The present invention relates to a kind of hot water dewaxing's techniques of low-temperature wax mould material sodium silicate shell, belong to Investment casting technology neck
Domain.
Background technique
Model casting, which refers to, is made model with fusible material, is then coated with refractory material on model again, after hardened, then will
Model melts, outside discharge type, to obtain adding to the fun without die joint.It is manufactured since fusible pattern is widely used wax material, therefore again
Model casting is often referred to as " lost-wax casting ".Again due to the casting of acquisition dimensional accuracy with higher and surface smoothness,
Therefore also referred to as " precision-investment casting ".
The molten process lost of fusible pattern is known as dewaxing, and dewaxing is one of critical process of investment pattern precision casting, and sodium silicate shell is parked
Period is also the process for remaining curing agent in shell and continuing hardening to dope layer, with the growth of storage period, shell it is wet strong
Degree increases, and with the progress of dehydration and drying, gelinite will more fine and close, intensity increases, water-resistance enhances, simultaneously because dewaxing
Hot water temperature it is higher, be easy staff is scalded.
Summary of the invention
The main purpose of the present invention is to provide a kind of hot water dewaxing's techniques of low-temperature wax mould material sodium silicate shell, can incite somebody to action
The clean removing of wax in sodium silicate shell, and can avoid personnel's scald, it can effectively solve the problems in background technique.
To achieve the above object, the technical scheme adopted by the invention is as follows：
A kind of hot water dewaxing's technique of low-temperature wax mould material sodium silicate shell, includes the following steps：
1) tap water is injected into cleaning dewaxing slot, dewaxing liquid is added, it is stirring while adding；
2) dewaxing slot cap relief valve, heating dewaxing liquid to fluidized state are opened；
3) the upper plane that dead head cup is brushed one times with hot water punching, removes floating sand；
4) mould group is fitly emitted in hanging basket, the mould group oral area of only one dead head should be placed upward, remaining is answered
Side is put, wherein a dead head cup should be at lateral extreme higher position, is conducive to smoothly go out wax；
5) rising switch to be pressed, pumps rod iron horizontal under hanging basket, a hand steered hanging basket, basket and slot frame collide when anti-decline,
Another hand presses down switch, and hanging basket drops to the cross-arm of top with until edge contacts on slot frame, and mould group enters slot；
6) after mould group enters slot, vapor volume is increased, dewaxing liquid is made to rise to suitable temperature as early as possible；
7) the dewaxing middle and later periods takes out the wooden stick on tank liquor face, scoops out wax liquor into processing cylinder with plastic barrel；
8) when no longer emitting wax at dead head, by rising switch, hanging basket is risen to above slot, and two rod irons are put on slot frame,
Hanging basket is fallen surely on rod iron；
9) raffinate is poured out on hanging basket, and formwork is removed to ground mouthful and is placed upward, is filled one by one into formwork while hot low
It is pouring in 60 DEG C of water and when rocking；
10) after rinsing well, with edge on the coating application dead head cup of shell process processed, exposed sand material, flange are fixed
Locate to lack at surface layer shell and answers paint.
Further, the dewaxing liquid is the NH4CL solution of content 3-5%.
Further, the suitable temperature in the step 6) is 92-98 DEG C.
Further, the dewaxing time is no more than 80min.
Further, need to survey the concentration of dewaxing liquid in water after dewaxing liquid is added in the step 1) every time, it will
The concentration of dewaxing liquid in water is adjusted to 3.5%-5%.
The present invention is clean by wax fusing removing under the cooperation of dewaxing liquid and hot water by the way that dewaxing liquid is added in hot water, leads to
It crosses and mould group is put into hanging basket, then the lifting of hanging basket is controlled to carry out control mould group disengaging dewaxing slot by electronic mode, keep away
People is exempted from directly to contact with dewaxing slot, personnel is prevented to be burned.
Specific embodiment
