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 a kind of mouth mould that can exhaust.
Background technology
As shown in Figure 1, in the manufacturing process of vial, need to by the frit melting 1 by blank mould 2, mouthful mould 3, mouthful circle 4, fuse (not shown) and silently the cooperation of (not shown) make just one-step forming of vial, wherein, mouth mould 3 is used for forming vial bottleneck, it comprises male model and master mold, mainly forms the global shape, size, whorl of bottleneck of bottleneck etc., is one of important mould of manufacturing by vial.
But in prior art, due to blank mould and the inner relative closure of mouthful mould, in frit enters into blank mould and mouthful mould successively time, gas in frit extruding blank mould and mouthful mould makes in blank mould and the inner vacuum that forms of mouthful mould, closure in blank mould has caused frit blanking bad, even cause frit to jump the phenomenon such as material or inclined to one side material, the closure in mouthful mould has caused not circle, the not reciprocity problem of finish dimensional of vial bottleneck simultaneously, and these are having a strong impact on the quality of production of vial.
Above-mentioned because blank mould and the inner relative closure of mouthful mould have a strong impact on the problem of vial quality in order to solve, imagination is provided with air discharge duct on mouth mould at present, when exhaust is realized in mouth mould inside, between mouth mould and the mating surface of blank mould, also can realize exhaust, so just can solve the not problem such as circle and frit jumping material of bottleneck simultaneously, improved the quality of vial entirety, thus the present invention proposes a kind of can improve the vial quality of production can exhaust mouth mould.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, proposed a kind of can improve the vial quality of production can exhaust mouth mould.
Technical scheme of the present invention is achieved in that
A kind of mouthful of mould is provided with many air discharge ducts on the upper surface of mouth mould, and every air discharge duct is inside, air expansion bottle oral cavity and outside air by being arranged on venting hole on blank mould, and the upper surface of described mouthful of mould is that mouthful mould is engaged in the end face on blank mould; Described upper surface is stepped on longitudinal cross-section, and wherein the middle portion of upper surface is higher than outer ring part, is arranged on air discharge duct on upper surface also stepped accordingly on longitudinal cross-section.
In the prior art, the gas pushing during due to frit blanking in blank mould and mouthful mould makes in blank mould and the inner vacuum that forms of mouthful mould, thereby caused the bad and bottleneck of frit blanking the problem such as circle had a strong impact on the quality of production of vial, now be provided with again many air discharge ducts in the upper end surface of mouth mould, specifically, in the time of gas in frit blanking extruding blank mould and mouthful mould, gas is finally discharged extraneous discharged to the venting hole of blank mould after being arranged on mouthful air discharge duct of mould upper surface again, avoided frit jump material and bottleneck circle etc. phenomenon, the quality of production and the production efficiency of vial are improved, meanwhile, air discharge duct is stepped on longitudinal cross-section, and middle portion, higher than outer ring part, makes the free air delivery of air discharge duct ascending, is convenient to the smooth discharge of gas.
As preferably, described air discharge duct is stretched out along the line and is comprised successively interval A, interval B and interval C by die cavity, and wherein the development length of interval A is 3～5mm, and the degree of depth is 0.1～0.15mm; The development length of interval B is 5～8mm, and the degree of depth is 0.2～1.2mm; The development length of interval C is 8～26mm, and the degree of depth is 2～10mm.Short and the depth as shallow of described A length of an interval degree, this is having ensured in blank mould and mouthful mould outside gas purging, also be the possibility in order to prevent that glass metal from flowing out to air discharge duct, and interval B is to interval C, development length is more and more longer and the degree of depth is more and more darker, this is for make can be by interval B and interval C through interval A expellant gas and be discharged to rapidly the external world, prevent that interval A is ineffective, prevent that whole air discharge duct from losing the effect of exhaust, visible this stair-stepping being arranged on increases free air delivery simultaneously, also ensured the quality of production of vial.
As preferably, downward-sloping inclined-plane is arranged in the edge section of described upper surface, and wherein the angle number of degrees between inclined-plane and horizontal plane are 3～8 degree.This is upper surface in order to reduce mouthful mould and the precision of the lower surface of blank mould in the time coordinating, and reduces error, is beneficial to both cooperations.
As preferably, described air discharge duct comprises 3～6.
As preferably, male model and master mold are by coordinating to realize and fit tightly between many triangle muscle and groove, and described triangle muscle and groove are separately positioned on corresponding planar section.
As preferably, described triangle muscle comprises 2～3, and triangle muscle is located point-blank in a longitudinal direction.
Adopt the invention has the beneficial effects as follows of technique scheme:
The present invention be a kind of can improve the vial quality of production can exhaust mouth mould.The present invention is provided with again many air discharge ducts in the upper end surface of mouth mould, specifically, in the time of gas in frit blanking extruding blank mould and mouthful mould, gas is finally discharged extraneous discharged to the venting hole of blank mould after being arranged on mouthful air discharge duct of mould upper surface again, avoid frit to jump the phenomenon such as circle of material and bottleneck, improved the quality of production and the production efficiency of vial; Meanwhile, air discharge duct is stepped on longitudinal cross-section, and middle portion, higher than outer ring part, makes the free air delivery of air discharge duct ascending, is convenient to the smooth discharge of gas.
