Description

Plastic bottle closure processing mold

Technical field

The utility model belongs to technical field of mold, and in particular to a kind of plastic bottle closure processing mold.

Background technique

Plastic bottle and its accessory are common structures, are widely used in the packaging such as food, chemical industry, drug, the prior art Plastic bottle and its accessory mainly formed by injection mould processing, and the injection molding of the plastic bottle and its accessory of traditional technology Mold is mainly made of bed die, backform and ejecting structure, however in actual use, due to ejecting structure setting not Rationally, it is be easy to cause deformation of products or damage when ejecting operation, so that the processing of plastic bottle and its accessory can be seriously affected Quality and processing efficiency, applicability and practicability are restricted.

Summary of the invention

And a kind of use reliable and stable plastic bottle closure processing mould reasonable the purpose of the utility model is to provide structure setting Tool.

The technical solution for realizing the utility model aim is a kind of plastic bottle closure processing mold, including die holder, is arranged in institute The backform stating the bed die on die holder and being arranged on the bed die, is provided with die cavity on the bed die and backform, on the top The center of mould is fixed with injection hole, is provided with knock-pin on the bottom wall of the bed die, and the top surface of the bed die is provided with top Bed die body out, the ejection bed die body is in the die cavity of the bed die and the lateral surface of ejection bed die body rides over the bed die Mould intracavity wall on, the bottom center of the ejection bed die body by pin shaft is connected to the top of the knock-pin and on the top The side wall of rod and the bottom surface for stating ejection bed die body between be provided with lifting cylinder, the knock-pin will eject the ejection of bed die body Bed die and under the action of lifting cylinder will ejection bed die body overturning complete product depanning.

It is provided with guiding vertical slot on the mould intracavity wall of the bed die, is fixed with position on the outer wall of the ejection bed die body Set the vertical sliding block matched with the guiding vertical slot position.

Buffer spring is provided on the bottom wall of the guiding vertical slot.

The height of the ejection bed die body is identical as the die cavity height of bed die.

The utility model has the effect of positive：The structure setting of the utility model is reasonable, is provided with ejection bed die body, To which ejection bed die body to be ejected to the die cavity of bed die upwards in knock-pin operation, bed die then will be ejected by lifting cylinder again The lifting of body side makes to eject bed die body rotation completion product stripping, and it is convenient to operate, it is not easy to product is damaged, use is reliable and stable, Strong applicability and practicability is good.

Detailed description of the invention

In order to be more likely to be clearly understood the content of the utility model, below according to specific embodiment and combine attached Figure, is described in further detail the utility model, wherein：

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

(embodiment 1)

Fig. 1 shows a kind of specific embodiment of the utility model, and wherein Fig. 1 is the structural representation of the utility model Figure.

See Fig. 1, a kind of plastic bottle closure processing mold, including die holder 1, the bed die 2 on the die holder 1 is set and setting exists Backform 3 on the bed die 2 is provided with die cavity 4 on the bed die 2 and backform 3, is fixed with note at the center of the backform 3 Mouth 5 is moulded, is provided with knock-pin 6 on the bottom wall of the bed die 2, the top surface of the bed die 2 is provided with ejection bed die body 7, institute State that ejection bed die body 7 be in the die cavity of the bed die 2 and the lateral surface of ejection bed die body 7 rides over the die cavity of the bed die 2 On inner wall, the bottom center of the ejection bed die body 7 is connected to the top of the knock-pin and in the knock-pin by pin shaft 8 Side wall and the bottom surface for stating ejection bed die body between be provided with lifting cylinder 9, the knock-pin will eject bed die body and eject bottom Mould and under the action of lifting cylinder will ejection bed die body overturning complete product depanning.In the present embodiment, pass through backform and ejection Bed die body completes injection molding, and knock-pin connects external drive use.

It is provided with guiding vertical slot 10 on the mould intracavity wall of the bed die, is fixed on the outer wall of the ejection bed die body The vertical sliding block 11 that position is matched with the guiding vertical slot position.

Buffer spring 12 is provided on the bottom wall of the guiding vertical slot.

The structure setting of the utility model is reasonable, is provided with ejection bed die body, thus will ejection in knock-pin operation Bed die body ejects the die cavity of bed die upwards, and then will eject the lifting of bed die body side by lifting cylinder again makes to eject the rotation of bed die body Turn to complete product stripping, it is convenient to operate, it is not easy to damage product, use is reliable and stable, strong applicability and practicability is good.

Obviously, the above embodiments of the present invention is merely examples for clearly illustrating the present invention, and It is not limitations of the embodiments of the present invention.For those of ordinary skill in the art, in above description On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments Exhaustion.And the obvious changes or variations that these connotations for belonging to the utility model are extended out still fall within it is practical Novel protection scope.
