Anti-wear injection-molded cup lid

Abstract

The invention discloses an anti-wear injection-molded cup lid. The cup lid comprises a cup lid body; a threaded column is guided out of the lower end of the cup lid body; a sealing ring bayonet is arranged at the bottom end of the threaded column in a bulging manner; a concave heat-gathering condensate water back-dropping preventing groove is formed in the center of the end surface of the front end of the sealing ring bayonet; vapor dew adhering plastic particles are arranged on the groove surface of the bottom of the concave heat-gathering condensate water back-dropping preventing groove in abulging manner; an annular concave clamping groove is formed in the end surface of the front end of the sealing ring bayonet on the outer side of the groove surface of the bottom of the concave heat-gathering condensate water back-dropping preventing groove; a sealing ring is mounted in the annular concave clamping groove; a ceramic arc top cover is mounted on a lid body at the front end of the cup lid body in an embedded manner; and a ground belt is further arranged on the ring surface of the outer side of the cup lid body. In the manner, the cup lid as a cup lid type integrated injection-molded piece has the good wear resistance and the high heat preservation characteristic.

Description

technical field [0001] The invention relates to the field of cup lids, in particular to a cup lid of an anti-wear injection molded part. Background technique [0002] Injection molded parts refer to various injection molded products produced by injection molding machines, collectively referred to as injection molded parts, including various packaging, parts, etc. It is mainly made of materials such as polyethylene or polypropylene with various organic solvents added. The choice of plastic parts is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. The production of injection molded parts generally adopts compression molding, transfer molding, and injection molding. Lamination, molding and thermoforming are the shaping of plastics on flat surfaces. The above methods can be used in rubber processing. In addition, there are castings using liquid monomers or polymers as raw materials. Among th...

Problems solved by technology

[0003] Most of the cup lids are also made of injection molding, but the traditional injection molded cup lids have poor wear resistance and are easily damaged after long-term use. Moreover, the traditional injection molded cup lids have poor thermal insulation and can easily dissipate heat, which reduces the thermal insulation of the cup.
