Description
Technical field
Patent of the present invention relates to a kind of system of processing of precision casting, particularly relates to a kind ofly to be applicable to the manufacturing equipment of precision casting at the cast formwork of manufacture process, a kind of drying system that the drying mainly for cast formwork is arranged.
Background technology
Traditional precision casting, be made up of following nine steps, the first step: penetrate wax, second step: wax-pattern, the 3rd step: group tree, the 4th step: be stained with slurry, the 5th step: shell processed, the 6th step: dewaxing, the 7th step: cast, the 8th step: cleaning, the 9th step: finished product cast (the visible accompanying drawing Fig. 2 of details), in traditional step, from the process of being stained with slurry-shell-dewaxing processed, after being stained with slurry, formwork needs drying, wax pattern assemblies is become wax-pattern group by tradition, the most original drying mode is the drying of circulation car blowing method: will through being stained with slurry, shell rear overhang processed is hung on circulation car, fan is placed in circulation car surrounding or top, fan is adopted to carry out dry, this form due to circulation car and fan all maintain static, when causing drying, formwork wind-engaging side rate of drying is fast, and the side rate of drying of wind-engaging is not slow, the degree of drying of formwork is difficult to consistent, therefore, easily because the inconsistent formwork that causes of formwork drying degree ftractures when after carrying out the 6th dewaxing, the 7th step is poured into a mould, cause bleed-out water,
Comparatively advanced drying mode: for overcoming the defect that above-mentioned fixing blowing method causes, formwork drying mode develops into and adopts suspended chain to add fan and carry out drying, it is exactly the formwork after shell processed, do not hang on circulation car, but hanging over tens of rice in the suspended chain of hundreds of meters, suspended chain surrounding puts fan.Formwork turns not arrheaing, thus wind-engaging is more even; But suspended chain is once stop to is stained with slurry--shell operation processed, then can uneven drying; And due to suspended chain long flow path, institute takes up space large (usually on average every square can hang 3 string formworks), and humidity is difficult to decline, and makes drying time longer, and the drying simultaneously of a large amount of formwork easily causes batch mixing, and operating personnel is also difficult to the dry mass controlling formwork.
Especially according to technological requirement be usually stained with slurry and shell processed need repetition operation more than five times, because precision casting is applicable to the components and parts of accurate machine construction usually, therefore, there is following defect in traditional being stained with in slurry-shell-dewaxing process processed:
(1) traditional drying mode easily causes underdry, if once shell mould underdry, will cause watering
Produce bleed-out water during note, foundry goods glues sand, pore increases;
(2) operating risk is large, and traditional shell drying steps processed easily causes cracking bleed-out water, just there is the operating risk of personnel and equipment, also reduces finished product rate and production efficiency simultaneously;
(3) production cost is high, and because yield rate reduces, efficiency is not high, and operating risk is large, naturally adds production cost and reduces business efficiency.
Therefore, for the number of drawbacks of above-mentioned aspect, need reasonably to improve existing technology.
Summary of the invention
For above defect, the invention provides a kind of novel formwork drying system, change traditional drying mode completely, a closed spatial placement is utilized to become drying shed, the aridity of shell mould is judged by the temperature in Automated condtrol drying shed, humidity and drying time, because the temperature and humidity in whole room is even, can the quality of drying time completely in control room and dry formwork, to solve the series of defect that uneven drying causes, production procedure can be set, production control time and product quality simultaneously.
By above-mentioned improvement, to solve many deficiencies of prior art.
The present invention is by the following technical solutions:
A novel formwork drying system, comprising: drying shed body, insulated wall, air-conditioning, dehumidifier, temperature alarm, remote control gate, air blast, auxiliary equipment of air line, timer; The surrounding of described drying shed body is provided with insulated wall, and left and right and rear portion insulated wall are closed, is provided with remote control gate, the insulated wall of remote control gate both sides is provided with observation window in the middle of front;
