2, the crude green body of plastic-absorbing component arranges jut in the joint of base plates after two, and after jut cutting, after two, base plate tops and sidepiece form flange, and flange both can the intensity of stiffener, meanwhile, better can fit splice with the rear plate of refrigerator, avoid Lou bubble.
3, the convex tendon of arc-shaped is all designed on plastic-absorbing component side, base, and its advantage is: one, is conducive to plastics sucking moulding; Two, be convenient to cut edge location; Three, form fit structure with both sides maze trough after refrigerator side plate.
Accompanying drawing explanation
Fig. 1 refrigerator polycrystalline substance of the present invention plastic-absorbing component crude green body structural representation.
Fig. 2 is the refrigerator rear soleplate structural representation of gained after plastic-absorbing component trimming as shown in Figure 1.
Detailed description of the invention
See Fig. 1-2, the present invention discloses a kind of refrigerator polycrystalline substance plastic uptake method, and once by the disjunctor plastic uptake simultaneously of base plate member after two pieces, the crude green body of an obtained inner bag shape, then cuts crude green body, base plate after forming a pair.Specifically comprise the following steps:
1) as shown in Figure 1, plastics sucking moulding a pair rear base plate crude green body on plastic plate, described crude green body is connected by two rear bottom board symmetries, and the bulge-structure (1 in crude green body, point outline line is provided with outwardly, 2), the opening part of crude green body outwards turns down and forms cut part 8, is provided with the convex tendon 3 of the trend in arch in the both sides of crude green body along cut part 8 and bulge-structure 2.Plastic uptake groove 4 on the cut part at the open back place of base plate in the rear, after cutting cut part, groove location forms overlap joint step 16.The design of crude green body top bump structure (1,2) is to form flange after cut edge, and flange first can stiffener intensity, and second flange can be fitted better with the rear plate of refrigerator body, avoids Lou steeping.The both sides, top of bulge-structure arrange the empty avoiding seat 12 of some rigging screw, and the convex tendon on cut part, crude green body both sides arranges the empty avoiding seat 15 of rigging screw.
2) as shown in Figure 1, the plane formed along boost line a cuts the top of bulge-structure, the plane formed along boost line b cuts the both sides of bulge-structure and the cut part of crude green body, and after cutting cut part along the outside of groove 4, after forming a pair, base plate as shown in Figure 2.
3) on rear base plate top, some cable-through holes 14 are cut, cutting-up foaming mouth on foam hole platform 13.
See Fig. 1-2, manufacture the rear base plate of gained according to above-mentioned refrigerator polycrystalline substance plastic uptake method, its concrete structure is as follows: rear base plate comprises top 5, sidepiece 6, back, and back is provided with some reinforcement shallow slots 7, and this some structural strength is strengthened.Be provided with flange 11 at the opening part of top and sidepiece, the flange outer rim of both sides is provided with convex tendon 3, and described convex tendon extends to the base of sidepiece and the base at back.Convex tendon is arc-shaped, be conducive to plastics sucking moulding, after convex tendon is set, cut edge can be carried out easily and cut location, the flange convex rib structure of both sides also can form the fit structure of maze trough form with casing left side plate, left side plate is coordinated with the assembling of rear base plate tightr, and sealing sponge strip can be cancelled.The flange at top is provided with the avoiding hollow groove 12 of some rigging screw, and avoiding hollow groove is herein used for the rigging screw bottom empty avoiding refrigerator backplate, avoids assembling gap.
Outwards bend on the base at described back and be extended with overlap joint step 16, overlap joint step is formed after cutting by groove 4 and convex tendon 3, and during refrigerator body assembling, another plate of bottom half component rides on overlap joint step 16, completes location.
Be provided with foam hole platform 13 at top, foam hole platform 13 drawn to split along the cross recess indicating positions at top and can insert note bubble rifle.Also be provided with some cable-through holes 14 at top, cable-through hole is boss structure, for passing through the refrigerator parts such as built-in conductor and drainpipe, and can according to the cable-through hole of different model of refrigerator choice for use correct position.During use, the jut of boss is cut off and is through-hole structure.And the cable-through hole do not used retains boss structure, sealing process can be reduced.
The convex tendon on sidepiece base is provided with the avoiding hollow groove 15 of rigging screw, and avoiding hollow groove is herein used for the rigging screw bottom empty avoiding refrigerator left side plate, avoids assembling gap.
The present invention is with reference to the bottom member of current refrigerator pin-connected panel, the structure, shaping etc. of bottom member are transformed, adopt plastics sucking moulding technique, split again after plastic uptake, crude green body napex crossbeam both sides evagination be tube seat, top planes establish truncated cone-shaped note abscess, on round platform draw two cuttves can note bubble, arrange the little round platform of via hole of some power lines, drainpipe near abscess, as required round platform is cut during use and be through hole.
The present invention improves note foam structure, increases the courage limit structure coordinated with case shell, cancels and seals the technique such as sponge, adhesive tape auxiliary material more, can better avoid Lou steeping, and simplifies the operation of assembling, reduces costs.
