Description

A kind of glass bottle and jar mould shoulder insulation construction

Technical field

The utility model relates to container glass production technical field, specifically a kind of glass bottle and jar mould shoulder insulation construction.

Background technology

The production technique of glass bottle and jar is comparatively complicated thermal technology's moulding process, because of bottle-type, the difference that frit is heavy, production technique also has larger difference, as shown in Figure 2: mould 1 in use, same secondary mould 1 from top to bottom its temperature is uneven, three sections can be divided into substantially, because glass material blank is thickening gradually from top to bottom, so with heat be also increase gradually from top to bottom, but owing to embracing pincers less than 2, mould has the cooling of cold air track and mould cold wind, so the situation of reality has the B section temperature of embracing pincers 2 the highest, and C section comparatively B section is low about 90 degree, although A section does not have mould cold wind, but because of the less calories that frit brings, thus comparatively B section is low about 180 degree, so in order to enhance productivity, Improving The Quality of Products will manage the temperature difference at each for mould position to reduce.

This kind of thin-wall light-weighted product as illustrated in figs. ia and ib, expect heavy and light, bottle wall is thin, machine speed is high, shoulder portion below bottleneck, due to frit with less calories, the temperature of the die part of institute's mapping is just difficult to reach shaping necessary requirement, to such an extent as to the shoulder position of this kind of bottle-type easily occur shaping not full, have cold spot phenomenon, thus affect the quality of vial.

And cause the immediate cause of this kind of defect to be exactly that the die temperature at mapping position is low, and the way solving this kind of defective workmanship improves frit temperature often by taking, extends the indirect means such as reheat time to improve die temperature, but virtually add production cost and production cycle.

Summary of the invention

The utility model is the weak point that technical solution exists, and proposes a kind of glass bottle and jar mould shoulder insulation construction, to the die temperature at the shoulder position of below bottleneck can be promoted, thus improve production efficiency and product quality.

The utility model is that technical solution problem adopts following technical scheme:

A kind of glass bottle and jar mould of the utility model shoulder insulation construction, be provided with die cavity in described mould, described mould is evenly divided into three sections from top to bottom, is that bottom shoulder portion, body portion and bottle, its constructional feature is respectively:

In the shoulder portion of described mould, and one circle heat dam is set near described body portion; In the shoulder portion of described mould, the periphery being in described die cavity is evenly provided with insulation hole, is provided with steel ball for sealing at the top in described insulation hole;

The heat insulation structural between described shoulder portion and body portion is formed with described heat dam; The heat insulation structural between the shoulder portion die cavity inside insulation hole and the shoulder portion mould outside insulation hole is formed with described insulation hole.

The constructional feature of glass bottle and jar mould shoulder insulation construction described in the utility model is also: described heat dam is of a size of: 5mm is wide, 20mm is dark; The diameter 7mm in described insulation hole, the degree of depth is 50mm.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

The utility model is by arranging heat dam and insulation hole, hole Outboard Sections absorbs heat as much as possible less, prevent the heat losses of mould shoulder, be conducive to the temperature promoting mould shoulder as early as possible, thus do not need to improve the ratio of briquetting that frit temperature can ensure vial, not only save energy consumption and production cost, also improve production efficiency and the percentage of A-class goods.

Accompanying drawing explanation

Fig. 1 a is the thin-wall light-weighted bottle-type of a class of the prior art;

Fig. 1 b is another kind of thin-wall light-weighted bottle-type of the prior art;

Fig. 2 is mould using state schematic diagram in prior art;

Fig. 3 is the front view of the utility model mould;

Fig. 4 is the stereographic map of the utility model mould;

Number in the figure: 1 mould; 1a die cavity; 2 armfuls of pincers; 3 side cold wind are chewed; 4 heat dams; 5 insulation holes; 6 steel balls;

Embodiment

In the present embodiment, as shown in Figure 2, be provided with die cavity 1a in mould 1, mould 1 is evenly divided into three sections from top to bottom, is bottom shoulder portion, body portion and bottle respectively, the A section namely in Fig. 2, B section and C section;

A kind of glass bottle and jar mould shoulder insulation construction as shown in Figure 3, is in the shoulder portion of mould 1, and arranges one near body portion and enclose the heat dam 4 that about 5mm is wide, 20mm is dark; Because the temperature of A section is too low, will absorb the partial heat of B section, and this light material is heavy, the product of high machine speed, the temperature of B section also can not be too high, so the object arranging heat dam is exactly prevent the heat of B section to the transmission of A section, thus ensure that B section has a rational high temperature all the time;

As shown in Figure 4, in the shoulder portion of mould 1, the periphery being in die cavity 1a is evenly provided with insulation hole 5, is provided with steel ball 6 for sealing at the top in insulation hole 5; In concrete enforcement, insulation hole 5 is arranged on release chamber 1a and is about 15mm place, insulation bore dia 7mm, deeply about 50mm, and hole end surface place steel ball 6 seals; Due to the poor conductor that air in hole is heat, so with a circle insulation hole for boundary, the heat that hole medial type cavity segment absorbs not easily is delivered to outside hole, and the temperature of such hole medial type cavity segment is just easy is elevated to normal shaping required temperature, to ensure the normally shaping of vial in the short period of time.

The heat insulation structural between shoulder portion and body portion is formed with heat dam 4; Form the shoulder portion die cavity inside insulation hole 5 to be incubated hole 5 and to be incubated the heat insulation structural between the shoulder portion mould outside hole 5.
