Description

Blow-and-blow glass shaping mould

The utility model belongs to the glass bottle industry improvement of shape mould just.

Before the invention, all first shape moulds that is applicable to blow-and-blow glass bottle-making machine (as individual section machine) all are made up of first shape die body, openning mould and plunger tip clamp mechanism, funnel, the first-class several major parts of first blow.The first shape mould of this structure, because the existence of funnel separately, have three critical defects: one, in the operating process of system bottle, because funnel exists funnel to fall, mention this twice action, and puffing head could first blow after must waiting funnel to fall, mention puffing head then, puffing head is fallen just back cover after waiting funnel to mention again, the result has caused funnel and twice palikinesia of puffing head, cause the system bottle working hour to prolong inefficiency; Its two because action step is many, the working hour is longer, the became uneven, the particularly temperature difference band that forms because of the part heat radiation at the bottom of causing bottle makes a bottle wall cause two defectives that connect material, and an influence system bottle quality, also limited bottle to alleviating development; Its three owing to there is shape die body, funnel, puffing head three's interface fit just, making just on the one hand, shape Mould Machining precision increases, damage the interface easily in the system bottle production process, cause shorten die life, gas leaks and increases when also making first blow on the other hand, has increased the reactive loss of energy.

The contriver's of the invention purpose, to invent the first shape mould that a kind of novel being applicable to blows method glass bottle exactly, overcome above-mentioned three shortcomings, make and use the working efficiency that this novel first shape mould can improve the system bottle, improve system bottle quality, reduce gas and leak.

Structure of the present utility model can be illustrated by Fig. 1.The first shape mould of this blow-and-blow glass removes and contains shape die body (1) just, openning mould and plunger tip clamp mechanism (2), outside the puffing head (3), its making characteristics be at the beginning of the inner chamber top of shape die body (1) make funnel (4), and in puffing head (3), be manufactured with puffing valve (5) and distribution ring washer (6), the low profile of puffing head (3) should match with the shape of funnel (4), the making method of openning mould and plunger tip clamp mechanism (2) is just the same with existing known making method, it comprises the openning mould, openning die sleeve tube, fuse, clamp ring, envelope air-casing tube, parts such as fuse joint repeat no more herein.The making method of puffing valve (5) is almost the same with the making method of inlet and outlet valve in the oil engine, belongs to known technology.The making method of distribution ring washer (6) can be to stamp out 2～6 air distribution holes around a round iron plate, the center is threaded hole of tapping again, puffing valve (5) and distribution ring washer (6) all are movingly with being threaded between puffing valve (5) and distribution ring washer (6) and the puffing head (3).

Fig. 2 has specifically shown the structure of first shape die body (1).The technique of painting of this figure adopts the current technique of painting of China's glass bottle mould.The material of making first shape die body (1) can be with grey cast iron or alloy.

Blow-and-blow glass after improving like this is the shape mould just, because making just, shape die body (1) carries funnel (4), saved independent funnel, just make in blow-and-blow system bottle process, overcome the long shortcoming of single bottle of production process because of existing independent funnel to cause, reduce the palikinesia of funnel and puffing head, improved production efficiency; Simultaneously, owing to saved independent funnel, also just do not have cooperating between funnel and first shape die body, make Mould Machining easier, the life-span is also therefore longer; Moreover, owing to shortened single bottle of production time, reduced the local heat radiation time, reduced the temperature difference of material base different sites in the course of processing relatively, system bottle quality is improved, help bottle to alleviating development.Like this, the utility model has just overcome existing three main drawbacks of shape mould just, has reached goal of the invention.

Can change the rapid wear part in order to make the first shape mould of this blow-and-blow glass, top said puffing head (3) can also be divided into first blow headstock (7) and first blow valve body (8) two portions, as shown in Figure 3, this two-part connection can adopt close-fitting legal, also can be respectively after the tapping of joint portion by thread connection drive maintenance so that the first blow valve body ［ 8 ］ of rapid wear torn open.

The control method of the puffing valve in the utility model ［ 5 ］ can adopt spring control type, pneumatic gravity type boat davit or the like.What show among Fig. 1 and Fig. 3 all is the spring control type, and this control mode is made more convenient.Be made into the spring control type, only need between puffing valve ［ 5 ］ and distribution ring washer ［ 6 ］, to load onto stage clip ［ 9 ］ and get final product.The pressure of stage clip ［ 9 ］ only need guarantee that puffing valve ［ 5 ］ is closed when first blow not, and puffing valve when first blow ［ 5 ］ is opened and got final product, no particular requirement in the making.When adopting the spring control mode, distribution ring washer ［ 6 ］ plays two effects: first distribution; It two is ring washers as stage clip ［ 9 ］.Be made into pneumatic gravity type boat davit, then need not to adorn stage clip ［ 9 ］, act on the atmospheric pressure on the puffing valve ［ 5 ］ when utilizing the own wt of puffing valve ［ 5 ］ to add first blow, make puffing valve ［ 5 ］ be in out the valve state, under blow back pressure reduction and of the effect of material base expansion back, puffing valve ［ 5 ］ is closed when back cover to puffing valve ［ 5 ］ top power.At this moment, distribution ring washer ［ 6 ］ will mainly play the distribution effect.

In order to make the utility model practical more, and prolong its work-ing life, lonely shape ［ R ］ in the junction of the inside cavity wall ［ 10 ］ of first shape die body ［ 1 ］ and funnel ［ 4 ］ wall can also be made into.As shown in Fig. 1 and Fig. 3.Done very big advantage like this: one makes the first shape of glass more approach to be shaped; Its two, can avoid effectively forming low temperate zone in the junction, so both improved the glass quality of shape just, prolonged die life, also be convenient to the demoulding.The utility model carries funnel ［ 4 ］ just because of first shape die body ［ 1 ］, make that just interior lonely shape ［ R ］ is made in above-mentioned junction becomes possibility, and this just much die design persons want for many years to do and fail to accomplish.
