Described profiling core lower end is provided with air inlet air flue and outlet air flue, one end of air inlet air flue and outlet air flue One end is connected with cavity A, and the other end of air inlet air flue is connected on blowning installation, and the other end of outlet air flue, which is connected to, to be taken out On vacuum plant.

The small end of described push rod is adapted with the mider hole of through hole, and baffle plate is adapted with the internal layer hole of through hole.

Described through hole is obliquely installed, and the outer hole of through hole is higher than the internal layer hole of through hole.

The outer hole of described through hole is correspondingly arranged at the lower section of bottle cap screw thread.

The position that the outer hole of described through hole also corresponds to anti-theft ring is set.

The utility model has advantages below:It is simple in construction, the sidepiece of bottle cap is made from profiling core by the push rod of setting Separation, realizes the easily demoulding, it is not necessary to forced stripper mechanism, and being effectively guaranteed connecting bridge will not be pulled off in the demoulding, improve The qualification rate of product.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model;

The enlarged drawing that Fig. 2 is A-A in Fig. 1;

In figure, 1-upper mould, 2-lower mould, 3-profiling core, 4-mobile core, 5-push rod, 6-baffle plate, 7-air inlet Air flue, 8-outlet air flue.

Embodiment

The utility model is further described below in conjunction with the accompanying drawings, protection domain of the present utility model be not limited to It is lower described:

As depicted in figs. 1 and 2, be provided with bottle cap new stripper mould, including upper mould 1 and lower mould 2, upper mould 1 sprue gate and The lower top of mould 2 is buckled in, upper mould 1 is connected with lower mould 2 with drive device, is provided with profiling core 3 below described sprue gate, imitates The lateral surface of shape core 3 is adapted with the madial wall of bottle cap, and the cental axial position of profiling core 3 is provided with cylinder chamber, cylinder chamber The mobile core 4 being adapted to therewith is placed with, the shape and bottle cap of the upper surface of mobile core 4 and the upper surface of profiling core 3 Inner upper wall shape is adapted, and the big bottom in top of mobile core 4 is small, is formed between the bottom of mobile core 4 and profiling core 3 Cavity A, the lower end of mobile core 4 and cylinders, drive mobile core 4 to move up and down by cylinder.

Multiple through holes are provided with the side wall of profiling core 3, through hole is divided into outer hole, mider hole and internal layer hole from the inside to the outside And mider hole aperture is small and outer hole and internal layer hole aperture are big, through hole is obliquely installed, and internal layer of the outer hole than through hole of through hole Kong Gao, the outer hole of through hole is correspondingly arranged at the lower section of bottle cap screw thread, and the outer hole of through hole also corresponds to the position setting of anti-theft ring, Push rod 5 is placed with through hole, one end of push rod 5 is big and the other end is small, and the big end of push rod 5 is located in the outer hole of through hole and push rod 5 small end is located in the mider hole and internal layer hole of through hole, and the termination of push rod 5 in through hole internal layer hole is provided with baffle plate 6, push rod 5 big end is adapted with the outer hole of through hole;The described lower end of profiling core 3 is provided with air inlet air flue 7 and outlet air flue 8, enters One end of gas air flue 7 and one end of outlet air flue 8 are connected with cavity A, and the other end of air inlet air flue 7 is connected to blowning installation On, the other end of outlet air flue 8 is connected on vacuum extractor.

When being molded, mobile core 4 is driven to move up by drive cylinder, now through hole is located at cavity A side On wall, then by vacuum extractor the air in cavity A is taken away, now blowning installation is closed, because cavity A pressure is small, institute Moved together to cavity A directions with push rod 5 and baffle plate 6, now the big side portion of push rod 5 is concordant with the lateral wall of profiling core 3, The liquid charging stock of bottle cap is injected by sprue gate.

When being stripped after injection molding, first pass through drive device and remove upper mould 1, moved lower mould 2 by drive device Walk, then drive mobile core 4 to move down by cylinder, but mobile core 4 not exclusively exits the cylindrical cavity of profiling core 3, moves Cavity B is formed between the upper surface of ejector half core 4 and profiling core 3, now, through hole is similarly positioned on cavity B side wall, air inlet gas Road 7 and outlet air flue 8 are equally connected with cavity B, close vacuum extractor, open blowning installation, by air inlet air flue 7 to sky Blown in chamber B, because pressure is high in cavity B, baffle plate 6 and push rod 5 are moved to the direction away from cavity B together, and push rod 5 is acted on On different bottle cap madial walls, bottle cap sidepiece is supportted big, now, cavity B upper wall is the interior upper wall of bottle cap, therefore in the work of air pressure Under, bottle cap is blown, it is achieved thereby that the demoulding.

Described above is only preferred embodiment of the present utility model, it should be understood that the utility model is not limited to herein Disclosed form, is not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and environment, and It can be modified in contemplated scope described herein by the technology or knowledge of above-mentioned teaching or association area.And this area The change and change that personnel are carried out do not depart from spirit and scope of the present utility model, then all should be in right appended by the utility model It is required that protection domain in.
