The drinks it sells are mainly hot and cold drinks, and for the sake of filling and drinking (4), for the take-away consumers, they provide disposable plastic cups and paper cups. The part of the cold drink is mainly sealed by a film to prevent the cup (10) from seeping out. Hot drinks, because their seals will be dissolved and leaked due to heat ships, and the use of straws can also cause accidental burns, so they are often covered with a lid. However, the existing cup cover usually uses the outer ring buckle of its periphery to insert the cup cup mouth. Due to the insufficient clamping force when the buckle is stuck, the cup cover is often loosened due to external force, and the liquid overflows. Moreover, the fit between the cup lid and the cup body is not good, and the inconvenience is caused by the leakage of the liquid in the cup _ moving process towel. In order to overcome the above-mentioned problem of liquid spillage or leakage ♦ This article asks the in-depth discussion on the problem of the cup cover of the above-mentioned financial vestibule cup. The cup cover of the Republic of China Patent No. M384844 has been proposed. By using a ring piece outside the outer edge of the corresponding cup body and a smashing piece corresponding to the mouth of the cup body, the end edge of the cover body is formed with an opening and a downward groove of the groove. The groove can be clamped on the cup mouth to produce a stable clamping force and close force, and the utility model can loosen and can effectively prevent liquid leakage in the cup body. The cup cover is produced by injection molding, and the existing cup tray is arranged at the periphery of the end of the cavity and communicates with the mold 6 and the external space when the plastic is injected into the cavity. When the original air in the cavity is discharged through the vent hole, it is formed as a part of the inner ring clip and is directly connected to the part of the inner ring clip, so that the original air is not easily formed from the vent hole. The plastic shirt is not able to fill the part of the mold 6 / * 4. Therefore, when the cup lid is injection molded, the existing fine coffee is 4% as a complete piece of money. The cup of the cup is not ideal. In order to solve the above-mentioned existing disposable cup lid molds during injection molding, the problem of '==' has been actively researched and tested through years of experience in the manufacturing and research and development of related industries. Overcoming the existing disposable cup lid forming mold can not be quickly and effectively formed into a 'combined material to make the cup of the lid can be tightly buckled - cup mouth [invention content] To appeal is to provide a cup lid forming mold and the use of the mold two methods , the mold can be efficiently injected into the forming-cup cover, and the cup and the inner ring clip, the lower edge of the cup cover = seepage: the downward clamping ring groove, thereby clamping - the cup mouth Anti-coffee

The cup forming mold of the above-mentioned structural features can be made quickly and efficiently according to the 'F', and the lid of the cup can be buckled. The step includes: preparing a mold as described above, which includes the male molds i and . The mother core 2, and then the male and female molds 2 are clamped, and the plastic 5 is introduced into the cavity 3 through the injection hole U, so that the plastic 5 fills the gap and the cavity 3' The vacant gap 14 and the original air in the cavity 3 are respectively discharged to the external space through the first air passage 13 and the second air passage 4; after the plastic is cooled, the mold is opened again to eject the cooled molded plastic out of the mold, that is, A cup of cover is available. Further, in step, when the mold is closed, the second air passage 4 is like a conventionally known, :, f gas (the plastic that flows into the cavity 3 at the periphery of the end edge of the cavity 3) The original air in the cavity 3 can be broadcasted to the rear row of the second air passage 4, and since the gap 14 communicates with the cavity 3, the plastic will flow into the gap 14 at the same time as the injection. The gas is sucked to the first emulsion 13 and discharged, whereby the plastic can be quickly injected to fill the paving hole 3 and the gap 14, without the original gas in the fork occupying the influence of the extrusion. Referring to Figures 4 and 5, there is shown a schematic view of the cup lid 6 which is formed by the aforementioned mold. The shape of the cup cover 6 is opposite to that of the cavity 3 and the 1 gap 14. It mainly includes a cover body 6 and the end edge of the cover body is formed with an outer ring clasp 62 and a relative The inner ring clip 63 of the outer ring clasp (7) forms an opening downward ringing ring groove 64 at the end edge of the 5 盍 body 61, as shown in FIG. 5, thereby closing the hood cover 61 When a cup is opened, the lid 6 can be placed in the clip ring groove 64 by the cup. Specifically, the gap 14 between the ring body 12 and the protrusion U is the molding space ' of the inner ring clip 63 and the outer ring piece 62 is inside the cavity 3 from the ring body 12 The outer portion of the ring body 12, which is formed by the plastic filling of the space extending away from the side of the convex body 11 into the groove, is contoured to correspond to the inner contour of the clip ring groove 64 of the cup cover 6. In this embodiment, the ring body is further formed with a ring groove 16 which is located on a side of the ring body 12 away from the convex body u and which is connected to the B3. More specifically, the annular groove 16 is extended around the outer length of the outer side of the ring body 12 as shown in the figure. Thereby, the outer ring clasp 62 formed between the groove 21 and the ring body 2 is further formed with a rib 65; 1361134 the rib 65 can be buckled in the clip ring groove 64. The cup mouth effectively prevents the cup opening from escaping from the clip ring groove 64. According to the wire, the cup forming mold provided by the invention can inject a plastic into the cavity thereof, and discharge the original air in the cavity from the first and second air passages respectively, so that the entire injection project is ejected. The plastic can fill the cavity and the gap quickly and evenly, and (4) can efficiently produce the cup cover 6 with the retaining ring groove. Furthermore, the gap 14 and the clip ring groove 64 injection molded in the cavity 3 have a suitable thickness, so that the clip ring groove 64 can expand with the thickness of the cup mouth. The structural strength is not easily squeezed by external force and deformed away from the cup mouth. Therefore, the invention not only can effectively improve the yield of the cup cover injection molding, but also has a cup loop which can be clamped to a cup mouth to prevent the liquid in the cup from seeping out, and has a new one, and the progress is improved. Wherever, and in accordance with the relevant provisions of the Patent Law, 提起 file a patent application in accordance with the law, in view of the early approval of the patent by the Bureau, it is really sensible.
