Description

Mouth matching die of vacuum cup Technical Field The utility model relates to the technical field of vacuum cup processing, in particular to a mouth matching die of a vacuum cup. Background In the production process of the vacuum cup, the procedure of opening matching (namely the assembly of the inner container and the shell of the vacuum cup) is one of key links influencing the yield of products, and the traditional opening matching mold usually adopts a rigid positioning structure, so that the fluctuation of the dimensional tolerance of the inner container and the shell is difficult to adapt, dislocation, inclination or uneven gaps occur during the assembly of the inner container and the shell, and poor tightness or appearance defects are caused after welding. In order to solve the problem, the utility model provides a mouth matching die of a vacuum cup. Disclosure of utility model The object of the present utility model is to solve at least one of the technical drawbacks. Therefore, an object of the present utility model is to provide a mouth-matching mold for a thermos cup, so as to solve the problems mentioned in the background art and overcome the defects existing in the prior art. In order to achieve the above purpose, the embodiment of one aspect of the utility model provides a mouth matching die of a vacuum cup, which comprises a die shell, a liner supporting die holder, a shell supporting die holder, a base, a limiting column, a first spring, a second spring and a polyurethane pad, wherein the die shell is internally provided with a cavity, the liner supporting die holder is arranged in the cavity and is used for positioning a vacuum cup liner, the shell supporting die holder is movably matched with the liner supporting die holder and is used for positioning a vacuum cup shell, the base is internally provided with a pressing block in a sliding manner, the limiting column is arranged below the pressing block, the first spring is arranged in the cavity and is connected with the bottom of the shell supporting die holder, the second spring is arranged between the base and the pressing block and is used for enabling the pressing block to be separated from the limiting column, and the polyurethane pad is arranged between the cavity and the liner supporting die holder and is used for enabling the matching between the vacuum cup liner and the vacuum cup shell to be smoother. By any of the above schemes, preferably, the bottom of the mould shell is provided with a through hole and a first threaded hole which are communicated with the cavity, and the first threaded hole is internally provided with a countersunk screw. In any of the above embodiments, preferably, the first spring is disposed in the first threaded hole and connected to the countersunk head screw. By any scheme, the inner container supporting die holder is preferably multi-stage stepped cylindrical, a countersunk hole is formed in the inner container supporting die holder, the bottom of the outer shell supporting die holder is in a convex ring shape, and the convex ring is connected with the stepped part of the inner container supporting die holder. By any of the above schemes, preferably, the top of the pressing block is connected with the bottom of the mould shell, the top of the pressing block is fixedly provided with a flange, the flange is arranged in the through hole, and the flange is provided with a second threaded hole.
