The pairing suture is a kind of common and defective of being difficult to overcome in the glasswork production field, has a strong impact on the quality of glasswork, even glasswork integral body is scrapped.Especially those have the product of interior pressure request to glasswork, and like Beer Bottle, pairing suture too conference directly causes the glasswork blast, for human consumer's health is brought potential safety hazard.
The past people generally believe that the reason that causes the pairing suture to produce is owing to anchor clamps, clamp (glass blank being transferred to the instrument of shaping mould by parison mo(u)ld); Perhaps the tolerance clearance of mould causes; Therefore emphasis is poured into the class formation of anchor clamps, clamp, but produces little effect.
Summary of the invention
Task of the present invention is to provide a kind of glasswork oral area forming mould, and this mould can effectively solve the pairing suture problem that occurs in the glasswork.
The inventor finds that through long-term exploration the reason cause the pairing suture to occur has a lot, as clamp become flexible, the mould quality of fit is low, the mould open/close process is rocked etc.But also have a very important reason to be ignored by everybody always.Promptly when the blowing blank, oral area is moulding at first, and frit need turn over turnback in being transferred to shaping mould, in shaping mould, carries out the secondary blowing again.And in this process, the choma parts in the oral area forming mould rotate a certain angle in company with blank easily, thereby produce the pairing suture.And the inventor can avoid the generation of this phenomenon through Design Orientation device in this mould.
In order to achieve the above object; The technical scheme that the present invention adopted is: a kind of glasswork oral area forming mould; Comprise mouthful mould and choma; Wherein a mouthful mould is made up of the two lobes half module that respectively has die cavity opposite each other, and choma is configured in a mouthful mould inside, has in mouth mould set inside to prevent the locating device of choma in mouth mould inner rotation.Because the effect of this locating device has limited choma in mouth mould inner rotation, thereby has prevented the appearance of pairing suture well.
Above-mentioned technical scheme can also further be optimized for: said locating device is formed the corresponding cooperation with prominence of groove by the groove that is located on the half module with the prominence that is located on the choma.
Above-mentioned technical scheme can also further be optimized for: said groove is located on the joint close face of half module, and said prominence is the pin that is installed on the choma.Practice at present shows, this technical scheme of on fluting, choma on the joint close face of half module, selling was not only easy to process, when using but also accurate positioning, thereby can obtain better technique effect.
Above-mentioned technical scheme can also further be optimized for: said locating device has two groups, is mutually 180 degree and is provided with.Owing to increased the quantity of locating device, can better prevent the rotation of choma, thereby better realize the object of the invention.
In the technique scheme, the mounting means of pin on choma, can through aperture is set on choma, pin is realized in the mode of aperture internal fixing.The mode that pin can pass through close-fitting is at the aperture internal fixing, and the mode of connection that also can pass through other is at the aperture internal fixing.
Technical scheme provided by the invention since in mouth mould set inside prevent the locating device of choma in mouth mould inner rotation; Avoided the young material of glass is being transferred to the problem that the young material of choma drive rotates in the shaping mould process from parison mo(u)ld; Prevented that well bad mold joint and shaping mould that parison mo(u)ld is stayed on the goods blank from staying the dislocation between the bad mold joint on the finished product, thereby can effectively solve the pairing suture problem of glasswork in producing.
