Abstract
The present invention relates to a kind of integral forming process of combination transformer, after pour mass has watered in mainly comprising the steps:, enter in the one-time formed mould, adopt liquid two-component silicone rubber, use the liquid pressure injection to enter in the die cavity, carry out the disposable interior pour mass of sealing, baking is shaped to combination transformer; It is the liquid organosilicon rubber of two kinds of components of 20 and 50 that wherein raw material adopts hardness in DOW CORNING liquid organosilicon rubber LC 2004 series, is to make up batch mixing at 1: 0.9 with weight ratio under vacuum, totally enclosed situation.The effect that the present invention is useful is: 1, reduce raw-material waste than original technology; 2, the product than original explained hereafter increases by 30 year service life; 3, have a lot of outstanding advantage and characteristics through the liquid silastic that experiment showed, two components, as not yielding under in extreme temperature, long term exposure is still highly stable under the intensive ultraviolet radiation, link and sealing better, effectively prevent dielectric surface flashover.
Description
Technical field
The present invention relates to a kind of moulding process, especially a kind of integral forming process of combination transformer.
Background technology
Present combination transformer production technology is after interior pour mass has watered, and adopts the silicon rubber of sheet, in sticking on the pour mass.Existing technical matters deficiency is: the long-time use, the into water that comes unstuck easily makes gauging of products inaccurate, product rejection.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of integral forming process of combination transformer is provided.
The present invention solves the technical scheme that its technical problem adopts: the integral forming process of this combination transformer, after pour mass has watered in mainly comprising the steps:, enter in the one-time formed mould, adopt liquid two-component silicone rubber, use the liquid pressure injection to enter in the die cavity, carry out the disposable interior pour mass of sealing, baking is shaped to combination transformer; It is the liquid organosilicon rubber of two kinds of components of 20 and 50 that wherein raw material adopts hardness in DOW CORNING liquid organosilicon rubber LC 2004 series, is to make up batch mixing at 1: 0.9 with weight ratio under vacuum, totally enclosed situation.
Described pressure is from adopting 30 tons pressure injection in the blender in mould, and temperature: inject more than 60 ℃ from the temperature of start injection, by 1/3 o'clock of total amount, be warmed up to end about 120 ℃ injecting and finish, 120 ℃ of left and right sides pressurizes are about 2 hours.
The effect that the present invention is useful is: 1, reduce raw-material waste than original technology; 2, the product than original explained hereafter increases by 30 year service life; 3, than original features simple and practical process high efficiency; 4, after explained hereafter property moulding next time, become full closeding state.4, compare with other silicon rubber with common plastic, rubber, through experimental results show that, the liquid silastic of two components has a lot of outstanding advantage and characteristics, as not yielding under in extreme temperature, long term exposure is still highly stable under the intensive ultraviolet radiation, binding and sealing are better, effectively prevent dielectric surface flashover.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of combination transformer of the present invention;
Reference numeral: combination transformer 1.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing:
The integral forming process of this combination transformer, after pour mass has watered in mainly comprising the steps:, enter in the one-time formed mould, adopt liquid two-component silicone rubber, use the liquid pressure injection to enter in the die cavity, carry out the disposable interior pour mass of sealing, baking is shaped to combination transformer; It is that (LC 2004 serial fluid silicone rubbers provide the high transparent prescription of 7 kinds of different hardness scopes from 20 to 80 for the liquid organosilicon rubber of two kinds of components of 20 and 50 that wherein raw material adopts hardness in DOW CORNING liquid organosilicon rubber LC 2004 series, the present invention selects wherein two kinds, after experimental data proves that the liquid two-component silicone rubber of these two kinds of hardness mixes in proportion, performance indications are better), under vacuum, totally enclosed situation, be to make up batch mixing at 1: 0.9 with weight ratio.
Described pressure is from adopting 30 tons pressure injection in the blender in mould, and temperature: inject more than 60 ℃ from the temperature of start injection, by 1/3 o'clock of total amount, be warmed up to end about 120 ℃ injecting and finish, 120 ℃ of left and right sides pressurizes are about 2 hours.After interior pour mass has watered, enter in the one-time formed mould, adopt liquid two-component silicone rubber, use the liquid pressure injection to enter in the die cavity, carry out the disposable interior pour mass of sealing, the baking moulding.
Technological process: the consumption of getting the raw materials ready → adjust, locked mode → injection → pressurize, intensification → sulfuration → demoulding → get finished product.
Equipment of the present invention adopts the German liquid-state silicon gel make-up machine of two big class: a.Germany-2x;
B.HUAYI-200 China meaning silica gel injecting systems.
Characteristics of the present invention after interior pour mass is once sealed the baking moulding, are that full closeding state can not use for a long time out of doors and can intake, can not come unstuck.Make product pressure measurement accurate measurement, can reach more than 50 years service life.
Advantage of the present invention: 1, have high-tear strength;
2, good track resistance, strong hydrophobicity;
3, high-low temperature resistant, uvioresistant;
4, product one-shot forming, outward appearance do not have interface, do not have the vestige of pasting;
5, for a long time non-maintaining operation under adverse circumstances;
6, definitely control stealing, be beneficial to accurate line loss.
