Description of the Invention: [Technical Field of the Invention] The present invention relates to an injection molding die, a finger-type cap molding die, and a method of manufacturing the same using the same. [Prior Art] With many curry shops and beverage shops, the beverages they sell are mainly hot and cold drinks, and for the convenience of filling and drinking (4), they are disposable for the take-away consumers. The plastic cup and the paper cup, and the part of the cold drink is mainly sealed by the film to prevent the cup (10) liquid from seeping out. Hot drinks are often covered with a cup lid because their seals are hot and filthy and have a problem with accidental burns. However, the existing cup cover usually uses the outer ring buckle of its periphery to insert the cup cup mouth. 'Because of the lack of the clamping force of the wire, the cup lid often becomes gas and dissipates due to external force, resulting in liquid overflow. The phenomenon, in addition, the fit between the cup lid and the cup body is not good, often in the cup of the crane spine (4) swaying, causing inconvenience to the user. In order to overcome the aforementioned problem of liquid spillage or leakage, the applicant has in-depth discussion on the problems faced by the above-mentioned cup of the disposable cup, and has proposed the cover of the Republic of China Patent Office No. a ring piece corresponding to the outer edge of the cup body mouth and a corresponding inner ring clip of the cup body mouth, so that the end edge of the cover body forms an opening downwardly clamping ring groove, thereby the clip ring groove It can be clamped on the cup cup mouth to produce a firm clamping force and a close fitting force, and the frequency can be loosened at will, and it can effectively prevent liquid leakage in the cup body in 201244909. However, the lid is manufactured by the injection molding die, and the venting hole of the existing cup dies is located at the periphery of the end of the cavity and communicates with the cavity and the material space when the plastic is injected. The cavity (4), the original air in the cavity is discharged by the vent, but the part of the cavity formed into the inner ring clip is not directly connected with the vent, so that the original money is not easily exhausted from the vent. The holes are discharged, causing the air to abut against the top during injection molding without filling the cavity into a portion of the inner ring clip. Therefore, when the cup is injection molded, the arrangement of the existing rig is often unable to effectively form a cup cap having a _ clip, which makes the cup production yield less than ideal. In view of the problem of the above-mentioned existing disposable cup lid molds during injection molding, 'by years of experience in manufacturing and R&D of related industries, we are actively seeking ways to make decisions, and through continuous efforts in research and trials, The cup cover is extremely shaped, so as to overcome the shortcomings of the disposable cup cover being masked and unable to form the lid quickly and effectively, and at the same time, the cup of the (4) can be tightly buckled. SUMMARY OF THE INVENTION The main object of the present invention is to provide a cup forming mold and a manufacturing method using the same, so that the mold can efficiently project a cup cover, and the cup cover has an outer ring clip and a corresponding one. The ring clip is such that the lower end edge of the lid is formed with a σ downward nip ring groove for clamping the cup opening to prevent liquid leakage in the cup. 5 201244909 Cover and Weimu (4) Touch the cup mask, the cup: No.: Γ and - female model. The male mold includes - Zhao, - ring body and the ring body = nr outside the periphery of the (10) 'and the convex body in the π, gap 'the first airway system communication gap and the outside of the public The master mold = 2 mechanical position __, the domain public, the _ _ into a predetermined H and - the second air passage connecting the cavity and the external space, the mold passes the "gap" and the lag is away from the convex body One side extends the main 5H groove. In this way, the money can be used in the merging, so that (4) can quickly = full of the cavity and the gap, and the air in the original cavity and the room can be quickly discharged from the first and second airways respectively. Therefore, the injection molding and the yield can be effectively improved; wherein the ring body and the groove are filled into a thin outer piece, and the H is filled into a kneading clip. The outer ring clasp and the _--clip ring groove enable the injection molded cup cover to have the clip ring groove to tightly clamp the cup mouth, and the liquid in the cup oozes out. [Embodiment] The following is a description of the technical ship of the present invention and its intended effect, and is not intended to limit the scope of the invention to be protected. Please refer to Figure 1 to Figure 3. The invention provides a subtractive molding die comprising a convex male mode i and a concave human frequency 2. The male mold ^ 201244909 includes a - convex body η, a ring body 12 and a - air passage 13, which is disposed outside the post of the mail body 11, and forms between the female convex body 11 and the ring body 12. There is a gap 14 that connects the gap 14 to the external space. The master mold 2' includes an annular groove 21; wherein the male and female molds 2 are engaged, the convex body 11 and the ring body 12 are located in the groove 21, and a shape is formed between the male and female molds. a cavity 3 of a predetermined shape and a second air passage 4 communicating with the cavity 3 and the external space, the cavity 3 being connected to the gap Μ, and the cavity 3 is away from the side of the ring 12 away from the protrusion 11 Extending to the groove 2, more specifically, the shape of the groove 21 corresponds to the shape of the (10) 11 and the ring body 12 'when the mold is closed', a cup shape is formed between the male and female molds Then, as shown in Figure 2. And the width of the cavity 3 formed between the two sides after the joining of the male, the Lai, and the 2 is between 〇.3 mm and 0.5 mm, thereby filling the cavity 3 and the gap ^ After shrinking the plastic in the cold part, the thickness of the qingyu cover is between the Q 3 axis, so that it can be molded and has a good moderate structural strength by using a proper amount of plastic during the injection molding process. The thickness of the cup. Furthermore, the width of the first air passage 13 is preferably Q lmm, so that after filling the gap (, it is not easy to flow into the first air passage 13 and prevent the cooled molded cup cover from having burr debris. The problem arises. In the present embodiment, the slab 2 is provided with a injection hole 22, and the injection hole 22 communicates with the hua 3 and the outer lang, and the male gong is provided with a recess 15 at the position of the plucking hole ^. Preferably, the injection hole 22 is located at the central position of the mold 7 201244909 八 3, thereby taking the plastic from the outside of the 眺 杈 杈 3 3 And when leaving, so that the temperature is lower, and it is easy to cool the condensation and solidify 'the warmth is purely transferred, the money is made to fill the cavity mouth ... the gap is 14 ° and the pocket 15 is disposed in the injection hole 22 The relative position of the contact hole 22 is such that when the plastic hole 5 is ejected from the plastic 5, the plastic in the injection hole 22 is close to the cavity of the cavity 3, and then is further away from the mold in the injection hole 22. The plastic of the hole 3 then flows into the cavity 3; therefore, the low temperature of the first hole can be filled into the concave six 15 and the lower temperature is blocked due to solidification. The probability of occurrence of hole 3. For other possible implementations, the impurity hole 22 may be disposed on the male mold 1, and the recess 15 may be disposed on the female mold 2 correspondingly. Please refer to Figure 1 to Figure 3. The cup forming mold of the foregoing structural features can be quickly and efficiently produced in accordance with the following steps - a cup lid that can be clipped to the cup. The step includes: preparing a mold, such as the foregoing mold, comprising the male mold i and the female mold 2, and then molding the male and female molds 2 and 2, and then injecting the plastic 5 through the injection hole 22; In the cavity 3, the plastic 5 is filled with the gap 14 and the cavity 3, and the gap 14 and the original air in the cavity 3 are respectively discharged to the external space via the first air passage 13 and the second air passage 4; After the plastic is cooled, the mold is opened by opening the mold to eject the cooled plastic from the mold. Further, when the mold is closed, the second air passage 4 is as conventionally known; || 201244909 has an exhaust passage formed at the periphery of the end edge of the cavity 3 to allow the plastic 5 flowing into the cavity 3 The original air in the cavity 3 can be squeezed to the second air passage 4 and then discharged. 'Because the gap 14 is in communication with the cavity 3, the "Hai plastic will also flow into the gap while the material is being injected. 14 and squeezing the gas therein to the first air passage 13 and discharging, whereby the plastic can quickly eject and fill the cavity 3 and the gap 14 without being affected by the original gas occupied by the extrusion. . Further reference to Fig. 4 and Fig. 丨尔句田 returns to the chess set to produce the lid of the cup cover 6 . The cup cover 6 is shaped to correspond to the shape of the cavity $ and the gap 14. It mainly comprises a cover body 6 and the end edge of the cover body is formed with an outer ring buckle > 1 62 and - the outer ring The inner ring clip 63' of the cleat 62 has an end edge of the cover body 61 formed with a downwardly downward clip ring groove 64, as shown in Figs. 4 and 5; thereby, when the cover body 61 is closed to the "cup" The lid 6 can fit the cup-to-ground clip (10) into the clip ring groove 64. 1 body and ancient, the gap 14 between the ring body U and the convex body U is the space of the inner ring clip J, and the outer ring buckle piece 62 is in the cavity 3 from the ring The body Η extends from the side of the convex body U to the space of the groove and is filled with plastic, and the rim of the ring body i2 is replaced with the inner contour of the missing ring groove of the cup cover 6. Corresponding. In the embodiment of the invention, the ring body 12 is further formed with a ring = 16 ′. The ring groove 16 is located on one side of the ring body 12 far from the convex body n and = the cavity 3. More specifically, the ring groove 16 extends around the ^ 2, as shown in the figure. The outer ring clasp 62 between the groove and the ring (four) is more closely formed with a convexity; 9 201244909 The rib 65 can be buckled against the cup opening in the clip ring groove 64, thereby effectively preventing The cup opening is arbitrarily disengaged from the clip ring groove 64. In summary, the cup cap forming mold provided by the present invention can inject a plastic into its cavity, and discharge the original air in the cavity from the first and second air passages respectively, so that the entire injection process is ejected. The plastic can quickly and evenly fill the cavity and the gap, thereby efficiently producing the cup cover 6 having the clip ring groove. Moreover, the gap 14 and the clip ring groove 64 injection molded in the cavity 3 have a proper thickness, so that the clip ring groove 64 can be expanded and expanded with the cup mouth of different thicknesses, and also has a certain structure. The 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 clip ring groove which can be clamped against a cup mouth to prevent the liquid in the cup from oozing out, which has novel and advanced points. And in line with the relevant provisions of the Patent Law, 提起 file a patent application in accordance with the law's request for the Office to approve the patent as early as possible.
