When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

In addition, it should be noted that the terms of orientation such as left, right, up and down in the embodiments of the present invention are only relative concepts or reference to the normal use state of the product, and should not be considered as limiting. The following describes the implementation of the present invention in detail with reference to specific embodiments.

Fig. 2 shows an injection mold for producing a cup cover according to the present invention, which comprises an upper mold assembly 3 and a lower mold assembly 4. As shown in the attached drawing 1, the cup cover produced by the injection mold comprises a cover body 1 and a ring buckle 2, the ring buckle 2 is perpendicular to the cover body 1 and is integrally formed with the cover body 1, fingers can be conveniently inserted into the cup cover and lift the cup cover, and as shown in the attached drawing 8, the lower surface of the cover body 1 is provided with an annular or segment-shaped rib plate 11 which plays a role in reinforcement, so that the cup cover is firmer. Upper die assembly 3 is connected with lower die assembly 4 in a vertical sliding mode, and lower die assembly 4 comprises a lower die plate 41. Lower die assembly 4 includes bottom plate 45, installs backing plate 46 between bottom plate 45 and the lower bolster 41, and it gets material to be convenient for operating personnel to operate the mould bed height to suitable position. Guide rods 47 are arranged at four corners of the bottom plate 45, the guide rods 47 penetrate through the upper die assembly 3, and the upper die assembly 3 is guided to move, so that the die is more accurate, and dislocation is avoided.

A lower mold insert 42 is installed on one side of the lower template 41 close to the upper mold assembly 3, the surface shape of the lower mold insert 42 corresponds to the lower surface of the cover body 1, and a groove 421 corresponding to the rib plate 11 of the cup cover is formed on the lower mold insert 42. The upper die assembly 3 comprises an upper die plate 31, an upper die insert 32 is installed on one side of the upper die plate 31 close to the lower die assembly 4, the upper die assembly 3 moves downwards during die assembly, and an injection die groove 5 for forming a cup cover is formed between the lower die insert 42 and the upper die insert 32. The upper die component 3 is provided with an injection port 6 communicated with the injection die cavity 5. The injection mold cavity 5 includes a ring buckle cavity 51 corresponding to the ring buckle 2. An inclined guide post 43 extending obliquely upwards is mounted on the lower template 41, and the free end of the inclined guide post 43 is far away from the injection mold cavity 5. In this embodiment, an insert 44 is embedded in the lower template 41, an inclined mounting groove is machined in the insert 44, and the inclined guide post 43 is inserted into the mounting groove and fixedly connected with the insert 44.

As shown in fig. 3 to 7, the upper mold insert 32 is provided with a slide member 33, and the slide member 33 is horizontally slidably connected to the upper mold insert 32. The sliding member 33 includes a forming end 331 close to the cavity 5 and a guiding end 332 far away from the cavity 5, the guiding end 332 is provided with a guiding groove 3321, the guiding end 3321 is inserted into the guiding groove 3321 when the upper mold assembly 3 moves towards the lower mold assembly 4 and forces the sliding member 33 to move towards the cavity 5, and the guiding end 3321 of the sliding member 33 is inserted into the ring-fastening cavity 51 of the cavity 5 when the upper mold insert 32 is attached to the lower mold insert 42, so as to form a cavity corresponding to the ring-fastening 2 of the cup cover.

A limit block 34 is arranged on one side of the upper template 31 far away from the sliding part 33, the upper die assembly 3 moves upwards far away from the lower die assembly 4, when the inclined guide post 43 leaves the guide groove 3321, the guide end 332 abuts against the limit block 34, the sliding part 33 is prevented from being completely separated from the upper die insert 32, so that the sliding part cannot be used repeatedly, the relative position of the sliding part 33 and the upper die insert 32 is still at the position just leaving the inclined guide post 43, in this case, the inclined guide post 43 can still be just inserted into the guide groove 3321 of the sliding part 33 when the upper die assembly 3 moves downwards, and damage caused by part dislocation is avoided. The upper plate 31 is provided with a clearance groove 311 at a position corresponding to the inclined guide post 43 to avoid collision with the inclined guide post 43 when the upper mold assembly 3 moves downward.

The working process and principle are as follows: the upper die assembly 3 moves downwards to enable the upper die insert 32 to be attached to the lower die insert 42, the sliding part 33 is pushed by the inclined guide post 43 to be inserted into the upper die insert 32, and a shape corresponding to the ring buckle 2 of the cup cover is formed between the ring buckle cavity 51 of the injection die cavity 5 and the forming end 331 of the sliding part 33; as shown in the attached figure 3, molten plastics are injected into an injection groove die 5 through an injection port 6 to form the cup cover, and after a period of time, an upper die assembly 3 is moved upwards; as shown in fig. 4, in the initial stage of upward movement of the upper mold assembly 3, the sliding member 33 is pulled outward under the guide of the inclined guide post 43, and at this time, since the forming end 331 of the sliding member 33 is still partially inserted into the ring buckle 2 of the cup lid, the cup lid is confined in the insert 32 and lifted upward by the sliding member 33 away from the lower mold insert 42, and the preliminary demolding is completed; as shown in fig. 5, the upper mold assembly 3 continues to move upward, and at this time, the sliding member 33 is pulled outward by the inclined guide post 43 to separate from the ring buckle 2, and the lid falls downward, thereby completing the demolding. Rib plate 11 of lid 1 is thin narrow, and if receive the power of slope and easily make the rib plate 11 receive the extrusion to produce the deformation when breaking away from in lower mould mold insert 42's recess 421, consequently use slider 33 to lift the vertical upwards realization drawing of patterns of bowl cover better, make the bowl cover drawing of patterns safe complete more.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by the present specification, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
