Description
Technical field
The utility model relates to the processing of vial crude green body accessory, particularly a kind of blank mould be vented.
Background technology
As everyone knows, blank mould is one of important mould manufacturing vial, as shown in Figure 1-2, blank mould 1 is formed by male model 11 and master mold 12 cooperation, male model 11 with the planar section 10 of master mold 12 on be equipped with the die cavity 2 of up/down perforation, two die cavities 2 cooperatively interact and make to be formed with a bottle chamber in whole blank mould 1 inside, the face that male model 11 fits tightly when matching with master mold 12 is joint surface 3, in the concrete manufacturing process of vial, need the frit 4 that melts by blank mould 1, mouth mould 5, the cooperation of fuse 6 and silently (not shown) makes vial just one-step forming, but, in the prior art, when frit 4 enters in blank mould 1, because frit 4 air extruded in blank mould 1 makes to form vacuum in blank mould 1 inside, cause frit 4 blanking bad and cause vial shoulder thin, body meat thickness ununiformity, the problems such as bird swing, frit 4 is even caused to jump the phenomenon such as material or inclined material, drastically influence the quality of glass bottle products, if jump the more serious frit of material also can jump out outside blank mould, visible have great potential safety hazard.
In order to solve above-mentioned cause blank mould inner vacuum to cause due to frit charging frit bounce-back and have a strong impact on the problem of vial quality, the utility model proposes a kind of frit of avoiding be vented and jump the blank mould of material.
Utility model content
The utility model overcomes above-mentioned the deficiencies in the prior art, proposes a kind of frit of avoiding be vented and jumps the blank mould of material.
The technical solution of the utility model is achieved in that
A kind of blank mould be vented, blank mould is made up of two male models be combined together and master mold, male model with the planar section of master mold on be equipped with the die cavity of up/down perforation, two die cavities cooperatively interact and make to be formed with a bottle chamber in whole blank mould inside, the face that described male model and master mold fit tightly when matching is joint surface, joint surface protrudes from planar section, is formed with line of delimitation between joint surface and planar section; Be formed with a line of delimitation respectively in the both sides of a die cavity, described line of delimitation is arranged along die cavity edge wheel profile, the face of described joint surface for being formed between line of delimitation and die cavity edge wheel profile; Described joint surface has the air discharge duct of several air expansion bottle chamber and outside air, and described air discharge duct is positioned at lower part of joint surface.In the prior art because the air extruded in blank mould during frit blanking makes to form vacuum in blank mould inside, cause frit blanking bad and affect the quality of production of vial, now lower part of joint surface is provided with air discharge duct, avoid and in bottle chamber, form vacuum and cause jumping the phenomenons such as material, improve the quality of production and the production efficiency of vial; Simultaneously, joint surface arranges along die cavity external margin and protrudes from planar section, the setting of this joint surface decreases the cooperation area of joint surface of the prior art, reduce tolerance, because if coordinate area excessive, joint surface, once the phenomenon that whole cooperation will be caused bad of damaging, has influence on the quality of vial; Joint surface being done higher than planar section, the planar section on male model and master mold is not contacted, is for air discharge duct, gas is discharged the external world to provide space.
As preferably, described joint surface is higher than planar section 0.6 ~ 1mm.
As preferably, the degree of depth of described air discharge duct is 0.1 ~ 0.2mm.If the degree of depth of air discharge duct is excessively dark, frit can be caused to flow to air discharge duct place, drastically influence the quality of vial, if air discharge duct is excessively shallow, just do not reach the effect of exhaust, still frit can be caused to jump the phenomenon such as material, effectively do not solve the problem that the frit that causes blank mould inner vacuum to cause because of frit charging rebounds; The degree of depth that the utility model air discharge duct adopts is 0.1 ~ 0.2mm, and consider that frit is a kind of flow velocity fluid quite slowly on the one hand, the air discharge duct of this degree of depth can not make frit flow to air discharge duct place, is also the effect considering exhaust on the other hand.
As preferably, the width of described joint surface is 8 ~ 12mm.
As preferably, male model and master mold are that described triangle muscle and groove are separately positioned on corresponding planar section by many triangle muscle and coordinating and realizing fitting tightly between groove.Many triangle muscle instead of the rib of a whole piece protrusion of up/down perforation in prior art, if adopt rib of the prior art, just can block the air discharge duct in bottle chamber, affect exhaust effect; And adopting many triangle muscle, first air discharges extraneous by the endoceliac air of bottle through air discharge duct and then the space between adjacent triangle muscle.
As preferably, described triangle muscle comprises 2 ~ 3, and triangle muscle is located point-blank in a longitudinal direction.
The beneficial effects of the utility model that have employed technique scheme are:
The utility model is that the blank mould of material jumped by a kind of frit of avoiding be vented.The utility model is provided with air discharge duct in lower part of joint surface, avoids and in die cavity, forms vacuum and cause jumping the phenomenons such as material, improve the quality of production and the production efficiency of vial; Simultaneously, joint surface arranges along die cavity external margin and protrudes from planar section, the setting of this joint surface decreases the cooperation area of joint surface of the prior art, reduce tolerance, because if coordinate area excessive, joint surface, once the phenomenon that whole cooperation will be caused bad of damaging, has influence on the quality of vial; Joint surface done higher than planar section, the planar section on male model and master mold does not contact, and for air discharge duct, gas is discharged the external world and provides space.
