Description

A kind of disposable bottle cap and its molding die

Technical field

The utility model relates to rapid forming mold manufacturing technology fields, more specifically, it relates to a kind of Disposable bottle Lid and its molding die.

Background technique

It is well known that, in order to protect the equity of consumer, many commodity need anti-counterfeit package for Maintenance Market order, It is anti-fake to seem even more important especially for alcohol product.Currently, alcohol product is anti-fake mainly to make disposable bottle cap for bottle cap To prevent criminal from recycling.

A kind of disposable anti-false bottle cap, the anti-fake bottle are disclosed in the Chinese patent that Authorization Notice No. is CN104875951B Lid includes outer cover, bottle neck, lock tube and internal plug, and nessa installed is in lock tube, and bottle neck is installed on the top of internal plug, and lock tube takes internal plug and bottle Mouth is mounted in outer cover, is integrally formed disposable anti-false bottle cap.

Disposable bottle cap in the prior art be similar to it is above-mentioned, by the mechanical bond between each component, so that bottle cap It is merely able to destructive opening, effectively prevent recycling, still, this disposable Bottle cap structure is complex, needs larger portion The clamping engagement of part, assembling difficulty is larger, therefore higher cost.

Utility model content

Problem in view of the prior art, the purpose of this utility model is to provide a kind of disposable bottle cap and its shaping moulds Tool, has the advantages that structure is simple.

To achieve the above object, the utility model provides following technical solution: including shell, the inner wall of the shell with The outer wall of bottleneck is bonded；

Inner casing, the outer wall of the inner casing are bonded with the inner wall of bottleneck, and the upper end of the inner casing and the upper end of shell connect；

Connection cover, the connection cover are set to inner casing and stretch out on one end outside bottle, and the connection cover is connected to inner casing to be set It sets；

Thin-walled, the thin-walled is horizontally disposed, and the inner wall and connection cover of the thin-walled are connected close to one end of inner casing, described thin Wall with a thickness of 0.1-0.2mm.

By using above-mentioned technical proposal, contact of the bottle cap with bottleneck can be increased by the cooperation between inner casing and shell Area, the bottleneck so that inner casing and shell can not only be fixedly clamped, and effectively ensure the leakproofness between bottle cap and bottleneck, when When needing to drink, it is only necessary to using twist, pressure prevents from exerting a force to connection cover so that be destroyed can be by connection cover and inner casing for thin-walled Separation, to be simply done the unlatching work of bottle.

The utility model is further arranged to: the lower end of the shell, which is provided on a ring outer shell outer wall, to be provided with upwards Turn down the hanging part of setting.

By using above-mentioned technical proposal, when selling drink, label etc. can be hung on hanging part, be distinguished convenient for customer Know drink species.

Molding die provided by the utility model: including set gradually from top to bottom upper die holder, upper mounting seat, upper molding Mould, lower shaping mould, lower mounting seat and lower die holder are provided with the lower shaping column for being fed through lower shaping mould, institute in the lower mounting seat It states to be provided on upper die holder and extend in lower shaping column and the first injection molding tube of the stepped setting of outer wall, set on the lower shaping column The setting of the first injection molding tube of ring is equipped with the first type chamber for forming connection cover, the injection molding of ring first is fixed in the upper shaping mould Manage and extend to the upper shaping column in lower shaping column, be additionally provided on the lower shaping column be connected to the first type chamber setting and ring at Type column is arranged with the second type chamber for shell molds and inner casing, and the lower end surface of the upper shaping mould is provided with shaping column on ring and sets The injection slot for setting and being connected to second type chamber setting, there are for supplying between the cascaded surface and second type chamber of first injection molding tube The forming gap of shaping thin wall.

By using above-mentioned technical proposal, part plastic is perfused to the first type chamber by the first injection molding tube, so that this portion Divide plastic that can fill the gap between full first type chamber and the first injection molding pipe outer wall to form connection cover, meanwhile, pass through injection molding Slot plastic is perfused it is intracavitary to second type, enable this part plastic fill between full second type chamber and upper molding column outer wall and Gap between upper shaping column and the first injection molding pipe outer wall is to form inner casing and shell, and two parts plastic can be in the first injection molding tube Cascaded surface and second type chamber forming gap blend with formed connection inner casing and connection cover thin-walled；Because of the first injection molding tube Cascaded surface and second type chamber between there are smaller for the forming gap for shaping thin wall, plastic is relatively difficult to pass through, using point The mode of section injection molding is easier to mold complete thin-wall construction.

The utility model is further arranged to: the upper end of the lower shaping column is stretched out in upper shaping mould, the upper shaping mould Lower end surface be provided under ring form column outer wall setting and be connected to injection slot be used for for the molding third type chamber in hanging part.

By using above-mentioned technical proposal, it is intracavitary that the plastic being perfused from injection slot can flow to third type, to complete to hang The shaping work in portion.

The utility model is further arranged to: the lower shaping column, upper shaping column, the first injection molding tube, third type chamber and Injection slot is provided with more than one piece.

By using above-mentioned technical proposal, by the way that shaping column, upper shaping column, the first injection molding tube, third under upper more than one piece is arranged Type chamber and injection slot enable a molding die to form the disposable bottle cap of more than one piece simultaneously, effectively improve the life of disposable bottle cap Produce efficiency.

The utility model is further arranged to: the lower surface of the upper shaping mould is provided with injection hole, the upper shaping mould Lower surface be additionally provided with multiple tracks for being connected to the drainage channel of injection hole and Ge Dao injection slot, be provided in the upper mounting seat The second injection molding tube that discharge port is connected to injection hole.
