Abstract
The invention relates to an opening die. A plurality of exhaust grooves are formed in the upper end surface of the opening die; each exhaust groove is communicated with the inside of a bottle opening cavity and the outside air through exhaust holes formed in a primary die; the upper end surface of the opening die is the end surface where the opening die is matched on the primary die; the upper end surface is step-shaped on a longitudinal cross section; the middle part of the upper end surface is higher than the outer circle part of the upper end surface; the exhaust grooves formed in the upper end surface are also correspondingly step-shaped on the longitudinal cross section. Compared with the prior art, the opening die avoids the phenomena that a bottle opening is not circular, a glass material can jump and deviate so that the bottle opening is not circular and the like due to adoption of the exhaust grooves in the upper end surface; the production quality and production efficiency of a glass bottle are improved; and meanwhile, as the exhaust grooves are step-shaped on the longitudinal cross section and the middle part is higher than the outer circle part, the exhaust amount of the exhaust grooves is increased gradually, and gases can be successfully exhausted.
Description
Technical field
The present invention relates to vial crude green body processing accessory, particularly to a kind of can be with the mouth mould of aerofluxuss.
Background technology
As shown in figure 1, during the manufacturing of vial, needing for the frit melting 1 to pass through blank mould 2, mouth
Mould 3, the cooperation of mouth circle 4, fuse (not shown) and silently (not shown) make vial just one-step forming, and wherein, mouth mould 3 is used for
Form vial bottleneck, it includes male model and master mold, primarily form the global shape of bottleneck, size, whorl of bottleneck etc., be
Manufacture one of important mould of vial.
But in prior art, due to blank mould and the internal relative closure of mouth mould, when frit sequentially enters blank mould and mouth
When in mould, the gas that frit extrudes in blank mould and mouth mould makes to be internally formed vacuum in blank mould and mouth mould, the closing in blank mould
Property to cause frit blanking bad, or even cause frit to jump the phenomenon such as material or inclined material, the closure in mouth mould is made simultaneously
Become that vial bottleneck is non-round, finish dimensional not to the problems such as, these drastically influence the quality of production of vial.
In order to solve the problems, such as above-mentioned vial quality is had a strong impact on due to the internal relative closure of blank mould and mouth mould, at present
Envision and be provided with air discharge duct on mouth mould, while realizing aerofluxuss inside mouth mould, also can be real between mouth mould and the mating surface of blank mould
Existing aerofluxuss, thus to solve bottleneck non-round and the problems such as material jumped by frit simultaneously, improves the overall quality of vial, institute
With the present invention propose a kind of can improve the vial quality of production can be with the mouth mould of aerofluxuss.
Content of the invention
Instant invention overcomes above-mentioned the deficiencies in the prior art are it is proposed that a kind of vial quality of production of improving
Can be with the mouth mould of aerofluxuss.
The technical scheme is that and be achieved in that:
A kind of mouth mould, is provided with a plurality of air discharge duct, every air discharge duct is by being arranged on blank mould on the upper surface of mouth mould
Steam vent and air expansion bottle cavity interior and outside air, the upper surface of described mouth mould is a mouthful end face on blank mould for the mould cooperation；Institute
The upper surface stated is stepped on longitudinal cross-section, and wherein the mid portion of upper surface is higher than outer perimeter section, is arranged on upper surface
On air discharge duct also accordingly stepped on longitudinal cross-section.
Conventionally, as the gas in extruding blank mould and mouth mould during frit blanking makes in blank mould and mouth mould
Portion forms vacuum, result in frit blanking bad and the problems such as bottleneck is non-round thus having had a strong impact on the production matter of vial
Amount, is provided with a plurality of air discharge duct in the upper end surface of mouth mould now again, specifically, when frit blanking extrudes blank mould and mouth mould
During interior gas, the air discharge duct heel row that gas passes through to be arranged on mouthful mould upper surface is finally then exhausted from the external world to the steam vent of blank mould,
Avoid the phenomenons such as frit jump is expected and bottleneck is non-round, improve the quality of production and the production efficiency of vial；Meanwhile, aerofluxuss
Groove is stepped on longitudinal cross-section, and mid portion is easy to gas higher than outer perimeter section so that the capacity of air discharge duct is ascending
The smooth discharge of body.
Preferably, described air discharge duct is stretched out along the line by die cavity includes interval a, interval b and interval c successively,
The development length of wherein interval a is 3～5mm, and depth is 0.1～0.15mm；The development length of interval b is 5～8mm, and deep
Spend for 0.2～1.2mm；The development length of interval c is 8～26mm, and depth is 2～10mm.Described a length of an interval degree short and
Depth as shallow, this is outside ensure that blank mould and gas purging in mouth mould, flows out to air discharge duct also for preventing vitreous humour
Possibility, and interval b arrives interval c, and development length is increasingly longer and depth is more and more deeper, and this is so that arranging through interval a
The gas going out can vent rapidly to the external world by interval b and interval c, prevent interval a ineffective, that is, prevent whole aerofluxuss
Groove loses the effect of aerofluxuss it is seen that this stair-stepping being arranged on increases capacity simultaneously, also ensure that the production matter of vial
Amount.
Preferably, the marginal portion of described upper surface is arranged to downward-sloping inclined-plane, wherein inclined-plane and horizontal plane it
Between the angle number of degrees be 3～8 degree.This is for the precision reducing the upper surface of mouthful mould with the lower surface of blank mould in cooperation, subtracts
Little error, beneficial to both cooperations.
Preferably, described air discharge duct includes 3～6.
Preferably, male model and master mold are realized fitting tightly by the cooperation between a plurality of triangle muscle and groove, described
Triangle muscle and groove are separately positioned on corresponding planar section.
Preferably, described triangle muscle includes 2～3, triangle muscle is located point-blank in a longitudinal direction.
Employ technique scheme the invention has the beneficial effects as follows:
The present invention be a kind of can improve the vial quality of production can be with the mouth mould of aerofluxuss.The present invention is in the upper surface of mouth mould
Place is provided with a plurality of air discharge duct again, and specifically, when frit blanking extrudes the gas in blank mould and mouth mould, gas passes through to set
Put the air discharge duct heel row in mouth mould upper surface and be finally then exhausted from the external world to the steam vent of blank mould, it is to avoid frit jumps material and bottle
The phenomenon such as mouthful non-round, improves the quality of production and the production efficiency of vial；Meanwhile, air discharge duct is in ladder on longitudinal cross-section
Shape, mid portion is easy to the smooth discharge of gas higher than outer perimeter section so that the capacity of air discharge duct is ascending.
