Abstract
The invention relates to a small-opening heat insulation container polyurethane foaming device, which comprises an upper cover, a circumference fixing plate and a base, wherein the lower part of the circumference fixing plate is connected with the base, the upper part of the circumference fixing plate is buckled with the upper cover, an inserting opening used for inserting an opening of an inner liner and a compressed air interface communicated with the inserting opening are arranged in the base, a sealing ring is arranged in the inserting opening, and the sealing ring is embedded in an annular groove of the base. A foaming layer process for filling the heat insulation container comprises the following steps: installing the small-opening heat insulation container polyurethane foaming device on a production line; inserting the opening of the inner liner with a case into the sealing ring; and connecting an air pipe on the compressed air interface of the lower part of the base. When a fixed amount of liquid PU is injected in a sandwich layer of the case and the inner layer, after the upper cover is covered, the circumference fixing plate is merged. Then, compressed air is injected for resisting the foaming force so that the foaming reaches the qualified PU density, after the PU is completely cured, the compressed air supply is stopped, the upper cover is opened, the circumference fixing plate is released, and the full-plastic small-opening heat insulation container can be taken out.
Description
Technical field
The present invention relates to a kind ofly be used for to the anchor clamps of small-opening heat insulation container filled with polyurethane foam (PU) and with the filling process of this kind anchor clamps specifically a kind of small-opening heat insulation container polyurethane foaming device and foaming layer filling process to the cool-bag filled with polyurethane foam.
Background technology
Common foam device; As be used for polyurethane (PU) foam device of refrigerator and refrigerator insulation, and its inner and outer rigid metal construction anchor clamps that adopt, it is supporting shell and inner bag; When in the interlayer of shell and inner bag, injecting liquid PU; From the solidification process that expand into PU of liquid, the intensity of anchor clamps can enough support the expansive force that blowing agent produces, and makes the inner bag of refrigerator or refrigerator and shell indeformable.But for the all-plastic small-opening heat insulation container, rigid metal fixture support inner bag can't be put in inner bag inside, because oral area is less, so in the interlayer between shell and inner bag during filling PU, owing to do not have anchor clamps in the inner bag, inner bag is out of shape because of expansive force easily.
Summary of the invention
The objective of the invention is to design a kind of small-opening heat insulation container polyurethane foaming device and foaming layer filling process.
What the present invention will solve is to the shell of small-opening heat insulation container and the interlayer filled with polyurethane foam between the inner bag time, and the expansive force that produces because of blowing agent causes the yielding problem of inner bag.
Small-opening heat insulation container polyurethane foaming device of the present invention; Comprise loam cake, circumference fixed head and base; The bottom of circumference fixed head is connected with base; The top of circumference fixed head and loam cake snapping are provided with socket that is used for slotting inner bag oral area and the compressed air interface that is communicated with this socket in the base, be provided with sealing ring in the described socket.Sealing ring is embedded in the annular groove of base.
The technology of use small-opening heat insulation container polyurethane foaming device filling foaming layer of the present invention is:
Be contained in small-opening heat insulation container polyurethane foaming device on the production line, sealing ring has been inlayed in base inside.Insert the inner bag oral area of loading onto shell in the sealing ring, connect tracheae on the compressed air interface of base bottom.After injecting quantitative liquid PU in the interlayer of shell and inner bag, cover loam cake after, the circumference fixed head will close up.Injecting compressed air is being resisted foaming power then, and compressed-air actuated pressure is for being controlled at the 1-2 kilograms per centimeter
2, make foaming reach qualified PU density, after PU solidifies fully, interrupt compressed air, open loam cake, the circumference fixed head unclamps, and can take out product.
Structure of the present invention can be filled the compression air in inner bag (pressure is the 1-2 kilograms per centimeter
2), to support inner bag, offset the foaming and intumescing power of PU, make inner bag not change shape.But so with the all-plastic small-opening heat insulation container of the present invention's production high-quality.

Fig. 1 is a structural representation of the present invention.
Fig. 2 is the exploded view (movable hasp and hinge are not represented) that cool-bag is pressed from both sides in the present invention.
Fig. 3 is the front schematic view of Fig. 2.
Fig. 4 is the A-A generalized section of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
As shown in the figure, the present invention includes loam cake 1, circumference fixed head 4, circumference fixed head 10, circumference fixed head 11 and base 6.The bottom of circumference fixed head 4 is connected with base 6 through the hinge of adorning on the base 5, and the bottom of circumference fixed head 10 is connected with base 6 through the hinge of adorning on the base equally, and the bottom of circumference fixed head 11 is connected with base 6 through the hinge of adorning on the base too.The movable hasp 3 that the top of circumference fixed head 4 is provided with through circumference fixed head 4 snaps onto on the connection discount 2 of loam cake 1.The movable hasp that the top of circumference fixed head 11 is provided with through circumference fixed head 11 equally (not having expression on the figure) snaps onto on the connection discount 13 of loam cake 1; The movable hasp that the top of circumference fixed head 10 also is provided with through circumference fixed head 10 (do not have on the figure expression) snaps onto on the connection discount of loam cake 1 (figure on less than representing); After buckling well, this loam cake 1 is locked with circumference fixed head 4, circumference fixed head 10, circumference fixed head 11 each other.
Be provided with in the base 6 and be used for inserting the socket 9 of inner bag oral area 14 and the compressed air interface 8 that is communicated with this socket 9.Be provided with sealing ring 7 in the socket 9, be provided with annular groove 16 in the base 6, sealing ring 7 is embedded in the annular groove 16.
Circumference fixed head 4, circumference fixed head 10, circumference fixed head 11 structures are identical, are arcuate structure.
Process with device filling heat-preserving container inner bag 15 of the present invention and shell 12 comprises at least: the present invention is contained on the production line, and sealing ring 7 is inlayed in base 6 inside.Insert the inner bag oral area of loading onto shell 12 14 in the sealing ring 7, connect tracheae on the compressed air interface 8 of base 6 bottoms.After injecting quantitative liquid PU in the interlayer of shell 12 and inner bag 15, cover loam cake 1, circumference fixed head 4, circumference fixed head 10, circumference fixed head 11 will close up.Injecting compressed air is being resisted foaming power then, makes foaming reach qualified PU density, after PU solidifies fully, interrupts compressed air, opens loam cake 1, and circumference fixed head 4, circumference fixed head 10, circumference fixed head 11 unclamp, and takes out product and gets final product.
