Description
Technical field
The utility model relates to a kind of vacuum pressure impregnation pipe mold.
Background technology
Vacuum pressure impregnation pipe, as a kind of insulating component with higher mechanical strength and excellent electric performance, obtains in electric switch industry and uses more and more widely.Mold heated is the vital link of vacuum pressure impregnation pipe moulding process, directly has influence on the outward appearance of product, mechanical performance and electric property.The mold heated mode of current vacuum pressure varnished insulation pipe is mostly and heats die cavity with thermocouple, adopts and mainly there is following shortcoming in this way:
1, heating-up temperature is uneven, and because the die length of vacuum pressure impregnation pipe is longer, many group thermocouples need be adopted to heat each position of die cavity respectively, easily cause each site curing degree of product different, the obvious aberration of outward appearance, quality is unstable;
2, programming rate is too fast, easily occurs rushing warm phenomenon, affects the curing rate of product, causes product mechanical performance bad, increases the percent defective of product;
3, heat transmits ecto-entad, and products solidifying order also from outside to inside, easily causes interiors of products to produce excessive stresses, causes cracking, affect mechanical performance and the electric property of product;
4, complicated operation, because thermocouple organized by needs more, need connect successively during operation, expend time in.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of vacuum pressure impregnation pipe mold, solve heating-up temperature in existing mold mode of heating uneven, programming rate is too fast, and heat transmits ecto-entad and causes product cracking, complicated operation, time-consuming problem.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of vacuum pressure impregnation pipe mold, comprise core rod, described core rod is axially arranged with through hole, described through hole connects circulating line device, described circulating line device comprises flowline, oil return pipe and hot media feedway, and described core rod through hole, oil return pipe, hot media feedway are connected successively with flowline, forms the hot media closed circuit to the heating of vacuum pressure impregnation pipe mold.
Further, also comprise a temperature sensing device, described temperature sensing device is connected with hot media feedway, controls hot media feedway.
Further, described core rod through hole two ends also connect oil nozzle, and described flowline is connected by snap joint with the oil nozzle of oil return pipe with core rod through hole.
Heating means for vacuum pressure impregnation pipe mold, adopt above-mentioned vacuum pressure impregnation pipe mold.
Heating means for vacuum pressure impregnation pipe mold, the steps include:
Step 1: temperature sensing device controls hot media feedway, heats the hot media in hot media feedway;
Step 2: the hot media after heating flows in the through hole of core rod from core rod upper end through flowline, flows to the lower end of core rod, the temperature of hot media is from the upper end of core rod to lower end and pass to core rod heating from core rod Inside To Outside;
Step 3: hot media flows back to hot media feedway through oil return pipe after flowing out from lower end, temperature sensing device continues to control hot media feedway and heats hot media.
Adopt the beneficial effects of the utility model:
1, adopt the heating agent of homogeneous temperature to heat from top to bottom, heating-up temperature is even, improves the quality stability of product;
2, adopt oil to be heating agent, temperature is convenient to control, there will not be and rushes warm phenomenon, and the curing rate of product can quantified controlling, greatly reduces the generation of waste product;
3, adopt mode of heating from inside to outside, decrease the generation of internal stress, improve the quality of product;
4, oil pipe and core rod adopt snap joint to be connected, easy and simple to handle, have saved the operating time.
