Description

Technical Field

[0001] The utility model relates to the field of glass bottle production, in particular to a mouth mold for manufacturing a special glass bottle mouth. Background Art

[0002] There is a type of glass bottle on the market, which has a groove on the outside of the bottle mouth and is equipped with a buckle on the outside of the bottle mouth after production (such as: Budweiser brand Master Collection Beer). The groove is used for the buckle on the outside of the bottle mouth to be clamped. After the glass bottle is filled, the buckle seals the bottle mouth, and finally the label is attached to the connection between the groove and the buckle to complete the production. Usually, when producing the bottle mouth of the glass bottle, it is necessary to set a half-protrusion at the mold joint of the half-mold. When the two half-molds are merged, the two half-protrusions form a molding convex block, thereby forming a groove for the bottle mouth of the glass bottle. However, this molding method will cause the groove to be on the mold line of the protrusion of the glass bottle, resulting in a raised edge in the middle of the label due to the mold line when the label is subsequently affixed, causing inconvenience in labeling. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the utility model provides a mouth mold for manufacturing a special glass bottle mouth, aiming to solve the technical problem that the existing molding method of the glass bottle mouth will cause the groove to be on the raised mold line of the glass bottle, resulting in a raised edge in the middle of the label due to the mold line when the label is subsequently affixed, causing inconvenience in labeling.

When the external blowing head blows the glass embryo, the glass embryo forms a groove when the molding head is pushed in, so that the groove of the formed glass bottle is not on the mold line, avoiding a raised edge in the middle after the label is attached; when the bottle mouth of the glass bottle needs to be demolded, the primary mold body is separated from the two half-mold bodies, and the push head is pulled out, so that the push head drives the molding head to separate from the bottle mouth molding cavity, thereby facilitating the demolding of the bottle mouth of the glass bottle from the bottle mouth molding cavity, avoiding the molding head hindering the separation of the bottle mouth of the glass bottle.

[0031] Through the above technical scheme, when the two half-mold bodies 1 are merged with each other, the glass embryo 4 enters the interior of the bottle mouth molding cavity 3, and the primary mold body 2 hugs the top of the two half-mold bodies 1, so that the primary mold body 2 drives the push head 9 to move, and the push head 9 drives the movable rod 7 to move, and the movable rod 7 drives the molding head 8 to insert into the bottle mouth molding cavity 3. When the external blowing head blows the glass embryo 4, the glass embryo 4 is formed into a groove when the molding head 8 is pushed in, so that the groove of the formed glass bottle is not on the mold line, avoiding a raised edge in the middle after the label is attached; when the bottle mouth of the glass bottle needs to be demolded, the primary mold body 2 is separated from the two half-mold bodies 1, and the push head 9 is pulled out, so that the push head 9 drives the molding head 8 to separate from the bottle mouth molding cavity 3, thereby facilitating the demolding of the bottle mouth of the glass bottle from the bottle mouth molding cavity 3, avoiding the molding head 8 hindering the bottle mouth of the glass bottle from being separated.

[0032] It should be noted that the primary mold body 2 is a mold used in the prior art to form a glass bottle body.

[0037] Reference Figure 4 In some specific implementations, limiting protrusions 6 are provided on both sides of the movable rod 7 , and the other end of the elastic member 15 abuts against the limiting protrusions 6 .

[0038] Through the above technical solution, when the push head 9 drives the movable rod 7 to move, since the other end of the elastic member 15 contacts the limiting protrusion 6, the movable rod 7 moves to drive the limiting protrusion 6 to move, and the limiting protrusion 6 drives the elastic member 15 to be squeezed, so that the elastic member 15 is in a contracted state; when the push head 9 loses the thrust of the initial mold body 2, the elastic member 15 stretches, thereby driving the limiting protrusion 6 to move, and the limiting protrusion 6 drives the forming head 8 to separate from the bottle mouth forming cavity 3 through the movable rod 7.

[0039] Reference Figure 1-Figure 4 In some specific embodiments, the elastic member 15 is a high temperature resistant spring.

[0040] Through the above technical solution, the high temperature resistant spring is used to ensure that the high temperature of the glass embryo 4 during blowing will not cause the elastic member 15 to deform, thereby improving the stability of the elastic member 15.

Blocking blocks 16 are provided on both sides of the movable cavity 13, and the blocking blocks 16 are located between the limiting protrusion 6 and the push head 9.

[0042] Through the above technical solution, when the elastic member 15 stretches, the elastic member 15 drives the limiting protrusion 6 to move, and the limiting protrusion 6 is blocked by the blocking block 16, thereby preventing the movable rod 7 from popping out of the movable cavity 13 under the elastic force of the elastic member 15.

[0043] Reference Figure 4 In some specific embodiments, blocking bars 17 are provided on both sides of the movable cavity 13 , and the blocking bars 17 are located between the blocking block 16 and the push head 9 , and one end of the blocking bar 17 passes through the movable cavity 13 , so that the passing end of the blocking bar 17 faces the push head 9 .

[0044] Through the above technical solution, when the push head 9 drives the movable rod 7 to move, the blocking bar 17 will block the push head 9, thereby preventing the molding head 8 from being too inserted into the bottle mouth molding cavity 3, resulting in too deep a groove of the bottle mouth after molding.

[0045] Reference Figure 1-Figure 5 In some specific embodiments, the cross-sectional shape of the molding head 8 is a trapezoid, and the shortest width surface of the molding head 8 faces the bottle mouth molding cavity 3.
