[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1~Figure 4 , the utility model embodiment includes:

[0023] like Figure 1 and Figure 4 The glass mold for forming the bottle body and bottle shoulder shown in the figure includes: a bottle body forming mold and a bottle shoulder forming mold. The bottle body forming mold includes a male mold 1 and a female mold 2 opposite thereto. A first half bottle mold cavity 12 is concavely arranged on the front side of the male mold 1, and a second half bottle mold cavity 22 corresponding to the first half bottle mold cavity 12 is concavely arranged on the front side of the female mold 2. The bottle body is formed after the molds are closed.

[0024] A vertical positioning rib 11 is arranged on the front side of the punch 1 and is located on one or both sides of the first half bottle mold cavity 12. A vertical positioning groove 21 corresponding to the vertical positioning rib 11 is arranged inwardly on the front side of the die 2. The cooperation between the vertical positioning rib 11 and the vertical positioning groove 21 allows the punch 1 and the die 2 to be positioned left and right when they are molded together, thereby improving the accuracy of the left and right bottle body seam.

[0025] The bottle shoulder forming mold includes a first sheet mold 3 and a second sheet mold 4. The first sheet mold 3 is arranged on the top of the male mold 1, and the second sheet mold 4 is arranged on the top of the female mold 2. In the present embodiment, the first sheet mold 3 and the second sheet mold 4 are semicircular sheets respectively, and the tops of the male mold 1 and the female mold 2 are respectively concavely provided with semicircular grooves 25 corresponding to the semicircular sheets, so as to facilitate assembly.

[0026] like Figure 2 As shown, the first sheet mold 3 and the second sheet mold 4 are respectively provided with countersunk holes 43, and screws 44 are provided in the countersunk holes 43 to install and fix the first sheet mold 3 and the second sheet mold 4 on the male mold 1 and the female mold 2. Figure 3As shown, the bottom of the first sheet mold 3 and the bottom of the second sheet mold 4 are respectively provided with arc strips 7 extending downward along the arc edge of the semicircular sheet, and the semicircular groove 25 is concavely provided with an arc groove 26 corresponding to the arc strip 7. Through the cooperation of the arc groove 26 and the arc strip 7, the first sheet mold 3 and the second sheet mold 4 are positioned when installed on the male mold 1 and the female mold 2, thereby improving the assembly accuracy.

[0027] A transverse positioning rib 32 is provided on the front side of the first bottle shoulder forming cavity 31 on one side or both sides, and a transverse positioning groove 42 corresponding to the transverse positioning rib 32 is provided inwardly on the second sheet mold 4. In the present embodiment, the vertical positioning rib 11 is perpendicular to the transverse positioning rib 32. Through the cooperation between the transverse positioning rib 32 and the transverse positioning groove 42, the axial (thickness direction in the figure) positioning of the first sheet mold 3 and the second sheet mold 4 is performed when the mold is closed, so as to avoid the problem of upper and lower misalignment, thereby improving the axial positioning accuracy when the punch 1 and the die 2 are closed.

[0028] A first bottle shoulder forming cavity 31 connected to the first half bottle cavity 12 is concavely arranged on the front side of the first sheet mold 3, and a second bottle shoulder forming cavity 41 connected to the second half bottle cavity 22 is concavely arranged on the front side of the second sheet mold 4, and the bottle shoulder is formed after the molds are closed. Figure 1 and Figure 4 As shown, compared with the first half bottle mold cavity 12 and the second half bottle mold cavity 22, the first bottle shoulder forming mold cavity 31 and the second bottle shoulder forming mold cavity 41 are smaller in size, and it is not easy to process the exhaust structure.

[0029] The bottoms of the first sheet mold 3 and the second sheet mold 4 are respectively provided with exhaust grooves 5 extending to the front to discharge the excess gas in the first shoulder molding cavity 31 and the second shoulder molding cavity 41. The depth of the exhaust grooves 5 is 0.3-0.4 mm, and in this embodiment, it can be processed to 0.35 mm, which can discharge the excess gas in the first shoulder molding cavity 31 and the second shoulder molding cavity 41 and prevent the molten glass from entering the exhaust grooves 5.

[0030] The semicircular grooves 25 are respectively provided with exhaust holes 24 extending downwards, and the bottoms of the first sheet mold 3 and the second sheet mold 4 are respectively provided with deep grooves 6 connecting the exhaust grooves 5 and the exhaust holes 24, so that the gas entering the exhaust grooves 5 can be discharged downwards from the mold through the exhaust holes 24.

[0031] In order to improve the exhaust during the bottle body molding process, micropores 23 connected to the exhaust holes 24 are respectively arranged in the first half bottle mold cavity 12 and the second half bottle mold cavity 22. The diameter of the micropores 23 is 0.6~0.7mm. In the present embodiment, it can be processed to 0.65mm, which can not only deliver the gas in the first half bottle mold cavity 12 and the second half bottle mold cavity 22 into the exhaust holes 24, but also prevent the molten glass material in the first half bottle mold cavity 12 and the second half bottle mold cavity 22 from entering the micropores 23.

[0032] In summary, the glass mold for forming the bottle body and the bottle shoulder pointed out in the utility model can be used to form the bottle body and the bottle shoulder, enhance the exhaust effect during the molding process, and improve the positioning accuracy of the mold closing.

[0033] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
