Embodiment Construction
[0013] The present invention will now be further described with reference to the accompanying drawings,
[0014] A cup lid is composed of a plastic inner lid and a stainless steel outer lid. The diameter of the platform is smaller than the inner diameter of the cup mouth of the cup body. There is a circumferential groove on the outer edge of the circular platform, the width of which is slightly larger than the thickness of the cup mouth of the cup body. The thread matched with the mouth of the cup forms a complete flat circular plastic inner cover; on the outer surface of the flat circular plastic inner cover, the stainless steel outer cover is closely attached.
[0015] A clamp used for a cup cover and its assembly, including a pass clamp, which is constituted as follows: the pass clamp is a necking clamp 4 with a large mouth facing upward, and a positioning made of nylon with a positioning interval and a take-out hole is placed under the necking clamp. Fixture 1; the first ...

The invention discloses a cup lid and a fixture used by the cup lid and assembly of the cup lid and the fixture, belonging to the field of home appliance. The cup lid is characterized in that an inner lid is made from a food-grade plastic; the middle part is a round platform; a circumferential groove is arranged close to the outer edge of the round platform; convex edges surrounding the circumference are arranged on the outer edge of the groove; thread matched with the cup rim is arranged on the inner side of the convex edge to form an oval plastic inner lid; and a stainless steel outer lid clings to the outer surface of the inner lid. The assembly fixture is provided with a necking fixture; a positioning fixture is arranged below the necking fixture; a stainless steel outer lid workpiece is arranged in the positioning fixture; a round stainless steel sheet plate workpiece is arranged in the stainless steel outer lid, and the necking fixture with an upward big opening is sleeved in; and a plastic lid workpiece with an upward opening is inserted into the necking fixture, and the necking fixture is arranged below an impact pressure head. Through the invention, the use of other fastening members such as a pinch plate and the like or glue can be avoided, the materials are saved, the working time is shortened, and the production efficiency and product quality are greatly improved; and the long-existing difficulty in manually assembling complicated cup lid and cup plug is solved.
Description
technical field [0001] The utility model belongs to the field of household utensils, and relates to the design and manufacturing technology of cup lids, to be exact, the technology of assembling cup lids mixed with stainless steel and injection molding. Background technique [0002] Common cup lids are composed of an inner plastic lid and an outer steel lid, usually with a gusset or glue to fasten the two; the gusset has great limitations on the appearance of the lid and is easy to use for a period of time. Loose, and there is a quality risk; but not only the amount of glue used is large, but also the workload of cleaning the cup cover in the rear channel is increased, and the glue is easy to cause the cup cover to be defective, affecting the quality, and there are many assembly processes, high scrap rate, and high cost. [0003] Contents of the invention [0004] The invention provides a cup cover which does not need gussets or glue, has few assembly steps, low cost and...
