Description
Technical field
The present invention relates to refrigerator accessory, relate in particular to a kind of gasket for gap sealing between refrigerator door and casing.
Background technology
Seal strip for refrigerator door is to be arranged between refrigerator door and casing, to prevent the member that cold air leaks.
Current refrigerator gasket adopts soft PVC (PVC) material by extruder, to extrude the operations such as strip gum cover, fixed length cutting, magnetic stripe installation and gum cover welding and is made, and its profile is square frame-shaped.The cross section of strip gum cover is irregular different shaped as frame, and its top is provided with the protruding wedge for snapping in edge, refrigerator doors position groove along gum cover length direction, and its inside is provided with a rectangle cavity and several special-shaped cavitys; Rectangle cavity is positioned at the upper outer of cross section, and for placing magnetic stripe, other special-shaped cavity is vacant.
In soft PVC (PVC) material, contain a large amount of plasticizer, easily produce molecular migration and pollute the food in refrigerator; The poor flexibility of PVC material, in production process, its gasket goods are subject to External Force Acting and deform, thereby reduce sealing property; The cold resistance of PVC material is poor, and winter, easy hardening was followed the string, and causes sealing property to reduce; The poor heat resistance of PVC material, in the transportation of refrigerator finished product in summer, be easily heated and with the adhesion of refrigerator body inner bag.
In addition, existing magnetic stripe mounting process and gum cover welding procedure mainly rely on manual operation, and automaticity is low, and four corner solder places of gasket in use easily ftracture because of switch gate collision, cause cold air in case to leak.
Summary of the invention
For above-mentioned problems of the prior art, the object of the present invention is to provide a kind of removable without seam entirety seal strip for refrigerator door, its elasticity, sealing, heat insulating ability, heat resistance, cold resistance and anticollision performance are good, without plasticizer molecule, move, four corner's damages not easy to crack, can realize automated production, production process energy-conserving and environment-protective.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of removable without seam seal strip for refrigerator door, comprise by forming the gasket body of square frame-shaped structure with suitable four edges of refrigerator door, described gasket body adopts liquid urethane elastomer material through forming without the integrated poured sulfuration of seam, its excellent spring, dimensional accuracy is high and not yielding, has improved sealing property and the heat-insulating property of gasket; Described edge comprises protruding wedge, sealing thermal insulation limit and sealing adhesive part; Described protruding wedge is positioned at edge top, and extends to form along its length a square frame-shaped, for snapping in refrigerator door edge groove, has realized the dismounting function of gasket; Described sealing thermal insulation limit is positioned at edge middle part, and extends to form along its length a square frame-shaped, for sealing the gap between refrigerator door and casing, prevents that cold air from leaking; Described sealing adhesive part is positioned at edge bottom, and its inside is embedded with magnetic stripe, and extends to form a square frame-shaped along edge length direction, for refrigerator door is pull-in on to casing, has realized the closing function of refrigerator doors.
Another object of the present invention is to provide the removable manufacture craft without seam seal strip for refrigerator door, comprises the steps:
1. the working face of cleaning mold, particularly mould will be cleaned out, and will in die cavity, be coated with last layer interleaving agent for preventing the bonding of gasket finished product and mould;
2. in the cover half of horizontal positioned, inject appropriate liquid urethane elastomer, make liquid urethane elastomer cover mold bottom, form width identical with die cavity, there is certain thickness square frame-shaped sealing adhesive part base;
3. on the sealing of the square frame-shaped in cover half adhesive part base, inject the appropriate liquid urethane elastomer that contains magnetic, form the square frame-shaped magnetic stripe embryo that a width is less than sealing adhesive part base width, it is positioned at the middle part of the liquid urethane elastomer width injecting for the first time, and keeps mould to be in level; Or replace the liquid urethane elastomer that contains magnetic with the soft magnetic material of strip, by artificial or machine, according to the program of setting, soft strip magnetic material is moved to the assigned address being placed in cover half;
4. in the cover half that injects the liquid urethane elastomer that contains magnetic, re-inject appropriate liquid urethane elastomer, and keep mould to be in level; Or re-inject appropriate liquid urethane elastomer in the cover half of having placed the soft magnetic material of strip, and keep mould to be in level;
5. dynamic model is put into cover half slowly, make liquid urethane elastomer in cover half in the pressure current downflow of dynamic model and be full of die cavity, form the embryo of a gasket finished product;
6. mould after matched moulds is moved into baking moulding in baking oven, take out deburring after gasket finished product, clear up the clout of cavity body of mould inside simultaneously and coat interleaving agent for production next time; After the gasket deburring that adopts the soft magnetic material of strip to produce, be final products;
7. the gasket finished product after deburring is positioned over to the orientation of carrying out magnetic material on magnet charger and magnetizes, make it to obtain and have after the magnetive attraction of certain orientation, become final products.
The invention has the beneficial effects as follows: the elasticity of liquid urethane elastomer is high compared with PVC, sealing property and the heat-insulating property of its gasket are better; Cold resistance and the heat resistance of liquid urethane elastomer are good compared with PVC, and its gasket is not declined and hardening by weather temperature can, and in summer refrigerator finished product transportation, gasket can be because of hot environment and box liner adhesion; The contaminated food phenomenon without plasticizer molecule migration; Adopt integrated poured sulfidization molding technique, the anticollision performance of its gasket is good, has avoided four edge junctions to damage phenomenon because long-term switch gate collides the cracking producing.
