Description

Suction cup and manufacturing method thereof Technical Field The invention relates to the technical field of sucker manufacture, in particular to a sucker and a sucker manufacturing method. Background The sucker is widely applied to the electronic equipment support, and is favorable for helping the electronic equipment support to be adsorbed on the table top in vacuum so as to stably support the electronic equipment. In order to improve the stability of the sucker after being adsorbed on a table top, the sucker in the prior art is often provided with a circle of sealing ring, and the sealing ring and the sucker are fixed together in a glue bonding mode. The fixed sealing washer of sucking disc mode through glue bonding has a great deal of drawback in practical application, if sucking disc itself material is silica gel, and the sealing washer is comparatively soft material too, and the in-process of both bonding fixation is inconvenient fixed. In addition, in the mode of glue adhesion, when encountering high-temperature environment, the glue is easy to melt or age and lose efficacy, so that the sealing ring and the sucker are not firmly adhered. Disclosure of Invention The embodiment of the invention provides a sucker and a manufacturing method thereof, which can improve the reliability and the tightness of connection between a sucker body and a sealing ring. The invention discloses a sucker which comprises a sucker body and a sealing ring, wherein the sucker body comprises a connecting part positioned at the center and a supporting part connected with an outer ring of the connecting part, a cavity is formed by enclosing the connecting part and the supporting part, a mounting surface is formed on the supporting part, the sealing ring is arranged on the mounting surface, and the sealing ring is formed on the mounting surface in an injection molding mode. Optionally, the supporting part includes interconnect's expansion portion and supports and hold the portion, the expansion portion is round platform shape, the little mouth end of expansion portion with connecting portion connects, the big mouth end of expansion portion with support and hold the portion and be connected, the sealing washer is located support and hold the portion. Optionally, the plane of the abutting part is parallel to the plane of the connecting part. Optionally, the area of the abutting part corresponding to the sealing ring is provided with concave-convex textures. Optionally, the hardness of the sealing ring is smaller than the hardness of the sucker body. Optionally, the hardness of the seal ring is at least 10A less than the hardness of the chuck body. Optionally, the hardness of the sucker body is 30A-60A. Optionally, the hardness of the sealing ring is 0A-20A. Optionally, a vent hole is arranged on the connecting part, and the vent hole is used for connecting a negative pressure source. Optionally, a positioning hole is further formed in the connecting portion. Optionally, the sucker body is made of solid silica gel, and the sealing ring is made of liquid silica gel. The invention also discloses a manufacturing method of the sucker, which is used for manufacturing the sucker according to any one of the above steps, and comprises the following steps: The sucker body is made of solid silica gel and comprises a connecting part positioned at the center and a supporting part connected with the outer ring of the connecting part, wherein a cavity is formed by enclosing the mounting part and the supporting part, and a mounting surface is formed on the supporting part; the sucker body is arranged in a sucker mold, and a first cavity for injection molding of the sealing ring is formed on the mounting surface of the sucker mold; heating the sucker mold to 100-200 ℃; Injecting liquid silica gel into the first cavity and filling the first cavity; and cooling the sucker mold to enable the liquid silica gel to form a sealing ring on the mounting surface. The sucker and the manufacturing method thereof have the beneficial effects that the connecting part and the supporting part are enclosed to form the cavity through the connecting part positioned at the center and the supporting part connected with the outer ring of the connecting part. In practical applications, the connection portion can be connected to an external component (such as an electronic equipment holder, a negative pressure source, etc.). The supporting part is arranged around the connecting part so as to form a sealed space with the table top. The mounting surface is formed on the supporting part, the sealing ring is formed on the mounting surface in an injection molding way, so that the sealing ring is in seamless fit with the mounting surface, gaps possibly generated by glue adhesion do not exist, the reliability and the tightness of connection between the sucker body and the sealing ring can be improved, the air leakage in the cavity is reduced, and the adsorption force and the ads
