Abstract
The utility model discloses a kind of novel evacuated casing foaming sealing device, comprise top board, sealing strip and lower platen, described lower platen top is provided with notch, described notch is dovetail groove shape, described sealing strip is placed in notch, sealing strip shape and notch shape adapt, the downward crush seal bar of described top board.The utility model sealing strip the internal strain of lower platen notch be full of whole groove, and push the function that top board surface makes it to fit completely and completes isolated extraneous air, the restoring force of the dove-tail sealing strip that the utility model adopts is stronger and be difficult for dropping, and has effectively extended service life.
Description
Technical field
The utility model belongs to household electrical appliances equipment technical field of mold, relates generally to a kind of novel evacuated casing foaming sealing device.
Background technology
On domestic market, the operation principle of common vacuum chamber foaming is under the condition of isolated extraneous air, to carry out the foaming of refrigerator body, so the air-proof condition in foaming space is very important, on domestic market, common vacuum chamber foaming sealing device is and on lower platen, opens square groove, sealing strip cross section is circular, as shown in Figure 1, after this structure is repeatedly used, can produce sealing strip and recover poor, seal the phenomenons such as not tight, affect foaming quality, after using a period of time, need to change sealing strip, produce waste, when replacing, produce and need stop, production efficiency is lower.
Utility model content
The purpose of this utility model is to provide a kind of and uses simply, the novel evacuated casing foaming sealing device of long service life.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of novel evacuated casing foaming sealing device, comprises top board, sealing strip and lower platen, and described lower platen top is provided with notch, described notch is dovetail groove shape, described sealing strip is placed in notch, and sealing strip shape and notch shape adapt, the downward crush seal bar of described top board.
The height of described sealing strip is greater than the height of notch.
Between described sealing strip and notch, there is space.
Described sealing strip is polyurethane material.
Described top board and lower platen are steel matter.
The beneficial effects of the utility model: the utility model sealing strip the internal strain of lower platen notch be full of whole groove, and push the function that top board surface makes it to fit completely and completes isolated extraneous air, the restoring force of the dove-tail sealing strip that the utility model adopts is stronger and be difficult for dropping, and has effectively extended service life.
Brief description of the drawings
For the ease of it will be appreciated by those skilled in the art that below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is schematic diagram of sealing device in prior art.
Fig. 2 is the utility model structural representation.
Detailed description of the invention
As shown in 2 figure, a kind of novel evacuated casing foaming sealing device, comprise top board 3, sealing strip 2 and lower platen 1, described lower platen 1 top is provided with notch 4, described notch 4 is dovetail groove shape, described sealing strip 2 is placed in notch 4, and sealing strip 2 shapes and notch 4 shapes adapt, the downward crush seal bar 2 of described top board 3.The height of described sealing strip 2 is greater than the height of notch 4.Between described sealing strip 2 and notch 4, have space, described sealing strip 2 is polyurethane material.Described top board 3 is steel matter with lower platen 1.An inlet of vacuum tank foaming completes and starts to carry out matched moulds, top board 3 crush seal bars 2 make its distortion laminating, sealing strip 2 notch 4 internal strains of lower platen 1 be full of whole groove and push the function that top board 3 surfaces make it to fit completely and complete isolated extraneous air, the restoring force of the dove-tail sealing strip that the utility model adopts is stronger and be difficult for dropping, and has effectively extended service life.
Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
