Abstract
The utility model relates to a missile foaming encapsulating device. The missile foaming encapsulating device is characterized in that one side board of a pressure-bearing U-shaped part is provided with a pressure-bearing screw, and an encapsulating port covering board is provided with a covering cap; the encapsulating port covering board is provided with a through hole used for encapsulating, and the size of the covering cap is matched with the through hole; when the missile foaming encapsulating device is used, the encapsulating port covering board is fixed on a missile cavity needing to be encapsulated, foaming materials are evenly stirred and then poured into the cavity through an injection hole, and the through hole is sealed through the covering cap; the U-shaped port of the pressure-bearing U-shaped part is clamped on the missile cavity, and the pressure-bearing screw is screwed to a screw head to abut against the covering cap. The missile foaming encapsulating device changes a counter weight pressing mode adopted in the past, and has the advantages of being simple in structure, convenient to operate and good in reliability, and a missile circuit encapsulated by the device can meet 130-thousand g impact requirements. Production practice shows that the device can achieve batch production and greatly improve encapsulating efficiency. The device can also be popularized and applied to other foaming encapsulating operation.
Description
Technical field
The present invention relates to one and belong to mechanical field, be specifically related to a kind of body foaming encapsulating device.
Background technology
Missile-borne electronic device is with playing in emission process, and the acceleration that need to bear 1.3 ten thousand g impacts, and for guaranteeing that missile-borne electronic device normally works, prevents from impacting and causes device impaired and circuit working was lost efficacy, and must adopt certain measure to carry out consolidation process.Wherein overall package is exactly the effective method of one.
Method for packing is different along with the difference of encapsulating material, and epoxide resin material is all selected in general body encapsulation, adopts normal temperature to vacuumize encapsulation, and whole encapsulation does not need pressurized operation.Certain body is because be subject to weight limits, and its radar circuit embedding requires to select with lightweight, impact-resistant material, selects expanded material to carry out embedding, utilizes special encapsulating device complete operation.Because expanded material foams under free state, density is only 0.036g/cm
3shock-resistant very poor, for guaranteeing the requirement of shock-resistant 1.3 ten thousand g, the density that must control expanded material, we have designed foaming encapsulating device for this reason, by this device, control foaming and produce pressure, guarantee that foamed material foams completely in body inner chamber, make embedding agent reach estimated density, reach the requirement that the resistance to 1.3 ten thousand g high overloads of body impact.
Because foaming Embedding Material will produce very large pressure in foaming process, control pressure, can guarantee the density of expanded material, make the resistance to high overload of missile-borne electronic device of embedding impact requirement.
Summary of the invention
The technical problem solving
For fear of the deficiencies in the prior art part, the present invention proposes a kind of body foaming encapsulating device, meets embedding and bearing requirements by this device, realizes embedding operation, meets the overload-resistant requirement of missile-borne electronic circuit.
Technical scheme
A kind of body foaming encapsulating device, is characterized in that comprising embedding velar plate 1, block 2, pressure-bearing U-shaped part 3 and pressure-bearing screw rod 4; A side version of pressure-bearing U-shaped part 3 is provided with pressure-bearing screw rod 4, and embedding velar plate 1 is provided with block 2; Described embedding velar plate 1 is provided with the through hole that embedding is used, and size and the through hole of block 2 match; When use, embedding velar plate 1 is fixed on and is needed on the body of embedding cavity, after expanded material is stirred evenly, pour cavity into from hand-hole, block 2 seals through hole; The U-shaped mouth of pressure-bearing U-shaped part 3 is stuck on body cavity, tightens pressure-bearing screw rod to screw head and hold out against block 2.
U-shaped mouth size and the diameter of the projectile body of described pressure-bearing U-shaped part 3 match.
Beneficial effect
A kind of body foaming encapsulating device that the present invention proposes, adopt with embedding velar plate and circular block and realize the embedding operating process of expanded material, adopt the hold down gag with screw rod pressure-bearing form, withstand block by screw rod, bear the pressure that foaming produces, guarantee that foamed material does not overflow from body cavity, realizes the density of potting compound.Body foaming encapsulating device of the present invention is that foaming potting compound is poured into and is equipped with in the lid of this device and the body of cover plate, by the hold-down mechanism of this device, guarantee that blowing agent foams under blow pressure, guarantee that expanded material does not flow out, reach predetermined density, body is reached and meet anti-overload ability, guarantee the normal use of missile-borne electronic device.
The present invention has changed the counterweight pressuring method in the past adopting, and has simple in structurely, and the feature of convenient operation, good reliability, can meet 1.3 ten thousand g with the body circuit of this device embedding and impact requirements.Production practices show that this device can realize batch production, have greatly improved embedding efficiency.This device also can promote the use of in other foaming embedding operation.

The specific embodiment
Now in conjunction with the embodiments, the invention will be further described for accompanying drawing:
The embodiment of the present invention is by forming with embedding velar plate 1, block 2, pressure-bearing U-shaped part 3, pressure-bearing screw rod 4.Complete the embedding operation of components and parts in body 5 cavitys being carried out to expanded material.A side version of pressure-bearing U-shaped part 3 is provided with pressure-bearing screw rod 4, and embedding velar plate 1 is provided with block 2; Described embedding velar plate 1 is provided with the through hole that embedding is used, and size and the through hole of block 2 match; U-shaped mouth size and the diameter of the projectile body of described pressure-bearing U-shaped part 3 match.
Operating process is: first will cover with embedding velar plate 1 on the body cavity that needs embedding, tighten cover screw, after being stirred evenly, expanded material pours cavity into from hand-hole, cover circular block 2, the U-shaped part 3 in Fig. 1 and pressure-bearing screw rod 4 are installed by the position of Fig. 2 demonstration, tighten pressure-bearing screw rod to screw head and hold out against block 2, after foaming finishes, Unscrew takes off U-shaped part and block, and dismounting cover plate completes embedding operation.
