Abstract
The present invention provides a waterproof sealing ring formed by directly injecting elastic material onto a bearing housing, which comprises: a waterproof sealing ring made of elastic material; first, a housing for supporting the waterproof sealing ring; the shape and position of the waterproof sealing ring can be formed according to the requirement of the bearing shell on the three-dimensional shape and the waterproof sealing degree only by conforming to the forming principle of injection molding, and the groove and the tenon which are required when the bearing shell is installed with the waterproof sealing ring can be eliminated because the waterproof sealing ring is directly injected and formed on the bearing shell, and the forming and installing difficulty when the waterproof sealing ring is in the three-dimensional irregular shape is also reduced.
Description
Technical Field
The present invention relates to a waterproof sealing ring, and more particularly to a waterproof sealing ring, which is formed by directly injection molding to connect a waterproof sealing ring made of an elastic material with a bearing housing without a gap; because the direct injection molding method is used, the groove and tenon required for installing the waterproof sealing ring are not required to be additionally arranged on the bearing shell, and the waterproof sealing ring can be molded according to the requirement, the position and the waterproof sealing degree of the bearing shell on the three-dimensional shape only by conforming to the injection molding principle.
Background
In the general environment of waterproof sealing, because the waterproof sealing rings made of elastic materials are respectively formed, the bearing shell is additionally provided with a required groove and a required tenon when being installed with the bearing shell, and the bearing shell has a certain thickness; and because the waterproof sealing ring and the bearing shell are combined together after being respectively molded, a certain gap is formed between the waterproof sealing ring and the bearing shell, and the gap is also the reason for reducing the waterproof and sealing degree.
Because general waterproof sealing ring needs to be formed separately, so have certain thickness, requirement on the shape, because can also let this waterproof sealing ring cause the defective rate when shaping, demolding too high scheduling problem when having no certain thickness, normative shape.
However, the conventional O-ring used for waterproof sealing generally has a two-dimensional planar shape, but the required waterproof sealing position of the existing electronic communication related product is changed from the original two-dimensional planar shape to a high-low concave-convex three-dimensional shape due to many functional requirements, and when the waterproof sealing ring is required to be in a three-dimensional irregular shape, the reject ratio and difficulty in molding and installing the waterproof sealing ring are increased.
Especially in the demand on waterproof sealing degree, also let waterproof driving fit circle's section no longer only traditional circular curved surface, also may be the shape of this kind of non-traditional waterproof sealing circle of V-arrangement, oval shape etc. and the change of section shape like this is in order to let the fit degree that can assemble with upper and lower casing, waterproof performance is higher, nevertheless if still according to the fashioned production methods of tradition difference, then can cause the production mould too much, the difficult scheduling problem of production to produce produces.
Disclosure of Invention
In view of the above, the present invention provides a waterproof sealing ring, and more particularly, to a waterproof sealing ring, which is formed by directly injecting an elastic material into a bearing housing without a gap; because the direct injection molding is adopted, the bearing shell does not need to be additionally provided with a groove and a tenon which are required when the waterproof sealing ring is installed, and the waterproof sealing ring can be molded according to the requirements of the bearing shell on three-dimensional shape, position and waterproof sealing degree only by conforming to the molding principle of injection molding.
To achieve the aforementioned object, the present invention provides a waterproof sealing ring, which comprises: a waterproof sealing ring made of elastic material; first, a housing for supporting the waterproof sealing ring; the waterproof sealing ring made of elastic material is jointed with the bearing shell by injection molding, and the waterproof sealing ring can be formed according to the requirement of the bearing shell on three-dimensional shape, position and waterproof sealing degree, and because the waterproof sealing ring is directly jointed with the bearing shell, the groove and tenon required by the bearing shell when the waterproof sealing ring is installed can be reduced, the forming and installing difficulty when the waterproof sealing ring is in three-dimensional irregular shape can be reduced, and the waterproof sealing ring can be in three-dimensional irregular shape and can be completely sealed with the upper shell and the lower shell after being assembled.
Drawings
The objects of the invention and its attendant advantages will be further elaborated upon in the following description in conjunction with the accompanying drawings in which:
FIG. 1 is an exploded view of the present invention.
FIG. 2 is an assembled cross-sectional view of the present invention.
FIG. 3 is an assembly diagram of the present invention.
FIG. 4 is an assembled cross-sectional view of the present invention.
Detailed Description
FIG. 1 is an exploded view of an embodiment, which is implemented as follows: the bearing housing 11 for bearing the waterproof sealing ring is first manufactured by hot pressing, injection or press forming.
Then, the pre-formed bearing housing 11 is placed in the forming mold for forming the waterproof sealing ring 22, and the waterproof sealing ring 22 is injection-molded to complete the connection between the two.
FIGS. 2 and 3 are schematic sectional views of the embodiment, because the waterproof sealing ring 22 is formed by directly injecting and molding the elastic material, the waterproof sealing ring 22 can be formed according to the shape and position of the housing 11 for supporting the waterproof sealing ring; therefore, the waterproof sealing ring 22 can be formed according to the requirement of the three-dimensional shape of the bearing shell 11, such as height, concave-convex shape, etc.
Fig. 4(a), (b) are sectional views of the embodiment, according to the requirement of waterproof sealing, the waterproof sealing ring 22 can be formed into the required shape such as V-shaped groove 224, double V-shaped groove 224, etc., and the water-blocking bump 223 is generated at the peak of the V-shaped groove 224, so as to improve the sealing and waterproof performance of the waterproof sealing ring 22 after being mounted with the upper and lower housings.
Claims (5)
