The glass bottle pressure blow mould for preventing the wrong seam as shown in figure 1 comprises two forming moulds 1 which are assembled and disassembled, wherein the forming moulds 1 are semi-cylinders, and a cavity 2 is arranged on one surface which is attached to each other; the cavity 2 comprises a bottleneck section 21 and a bottleneck section 22, the bottleneck section 21 is in a gourd shape, and the bottleneck section 21 is communicated with the outside; the parting surface of the bottleneck section 21 is provided with a wear-resistant alloy layer 3, the alloy layer 3 is laid along the edge of the bottleneck section 21, and the alloy layer 3 is embedded into the forming die 1.

The utility model comprises an upper die and a lower die, wherein the upper die and the lower die are the same forming die 1 and also have cavities 2 with the same shape. The upper die and the lower die are semi-circular bodies, and the pressing and blowing die combined with each other is a cylinder. Make one side of going up mould and lower mould connect on the same axle, be convenient for fixed mould and lower mould's relative position, go up mould and lower mould and can laminate each other around the pivoting, the position is accurate, convenient operation, and it is fixed to use fixing means such as round pin axle to alternate moulded die 1 after the laminating. In the manufacturing of the die, the parting surfaces of the upper die and the lower die are the maximum section of the product, so that the product can be conveniently separated. The glass bottle produced by the utility model is similar to a cylinder in shape, the shape is symmetrical, and the parting surface should be at the middle position, so the shapes of the cavities 2 of the upper die and the lower die are the same. In addition, the cavity 2 comprises a bottleneck section 21 and a body section 22, the body section 22 is continuously narrowed towards the bottleneck section 21, the bottleneck section 21 is in a gourd shape, a glass bottle convenient for drinking is manufactured, and the appearance of the glass bottle is well loved by consumers. During pressure blowing, the glass paste is stretched into the cavity 2 from the bottleneck section 21, and then the glass paste is blown by using a blowing device, so that the glass paste is simultaneously attached to the bottleneck section 21 and the body section 22 for forming, and a final product is formed. Then, one of the forming molds 1 is rotated to take out the mold. It should be noted that, the bottleneck section 21 is short and narrow, and the bottleneck section 21 is gourd-shaped, so the bending section in the bottleneck section 21 has fine structure and large bending degree, and is easy to be damaged due to collision and friction, which affects the quality of the final product. The general hardware mould has insufficient hardness and wear resistance, the phenomena of larger mould joint line and staggered joint often occur in industrial production, the mould needs to be polished or replaced frequently, the cost of manufacturers is increased, and the production benefit is reduced.

In the present invention, the alloy layer 3 is additionally provided on the bottleneck section 21 by welding, melting, forging, spraying, or the like, so that the alloy layer 3 and the main body of the forming die 1 are integrally combined. As shown in fig. 1, the alloy layer 3 is completely embedded in the forming mold 1, and the alloy layer 3 is disposed on both side edges of the bottleneck section 21 to form a surface profile of the bottleneck section 21. In order to simplify the process, the alloy layer 3 is only disposed on the joint surface of the two forming dies 1, i.e., the parting plane, and does not completely cover the entire mouth section 21. Specifically, the thickness of the alloy layer 3 is about one third of the thickness of the bottleneck section 21, so that the alloy layer 3 has a relatively large volume and is not easily broken. In the process of combining or separating the upper die and the lower die, the alloy layers 3 are contacted with each other for collision and friction, and due to the high hardness and the high wear resistance of the alloy layers 3, the alloy layers 3 are not easy to damage in the collision and friction process, so that the long-term use of the die can be ensured.

In one embodiment, the alloy layer 3 is one of a nickel-based alloy, a copper-based alloy, an iron-based alloy, a high-manganese alloy, a tungsten carbide alloy, or an aluminum-silicon alloy. The alloy has high wear resistance and hardness, particularly the nickel-based alloy has high corrosion resistance and high wear resistance, can work for a long time in a high-temperature environment, and is suitable for industrial production.

In one embodiment, a bottle forming line 4 is arranged on a parting surface of the forming die 1, the bottle forming line 4 is positioned outside the cavity 2, the outline shape of the bottle forming line 4 is consistent with the outline shape of the cavity 2 on the parting surface, and the two parts are consistent in distance. The bottle forming line 4 surrounds the outside of the cavity 2 and is spaced apart from the cavity 2. Since the outline shape of the bottle forming line 4 coincides with the cross-sectional outline shape of the cavity 2 on the parting plane, the cavity 2 and the bottle forming line 4 are spaced apart by the same distance on any horizontal straight line. The worker can conveniently and visually observe whether the regions of the cavity 2 keep the same spacing distance with the bottle forming line 4 or not; if the spacing distance is different, the deformation of the cavity 2 is judged: for example, if the local position of the body segment 22 is damaged, that is, the contour edge of the body segment 22 on the parting surface is notched, or the contour line becomes wider, the arc line expands outward, and the worker can visually and quickly find the defect by comparing the spacing distances of the bottle forming line 4 and the cavity 2.

In one embodiment, the body section 22 is provided with grooves 5 at both sides, and the grooves 5 are adhered to the bottle line 4.

In one embodiment, the groove portion 5 is bent, and the groove portion 5 and the bent portion of the body section 22 are located at the same horizontal position.

The groove part 5 is hollowed on the parting surface of the forming die 1, is positioned at the outer side of the bottle forming line 4, and is attached to the bottle forming line 4, namely, the spacing distance between the groove part 5 and the cavity 2 is also equal to the spacing distance between the bottle forming line 4 and the groove part 5. When the glass bottle is manufactured by pressure blowing, the gas pressure in the cavity 2 is high, and great pressure is applied to the side wall of the cavity 2, so that the forming die generates stress which is fed back to the glass bottle product, and the glass bottle product is pressed. And through hollowing out the groove part 5, a thin-wall clamping glass bottle is manufactured in the forming die 1, so that the stress is reduced, and the production quality of the glass bottle is improved. Specifically, the glass bottle intensity of the bending section department of body section 22 is fragile, sets up concave part 5 in the position that corresponds with the glass bottle bending section, can alleviate the influence that mould stress produced the glass bottle, protects the fragile position of glass bottle.

In one embodiment, a pressure-bearing portion 6 is disposed on a side surface of the forming die 1, the pressure-bearing portion 6 annularly surrounds the forming die 1, and the pressure-bearing portion 6 is exposed on a parting surface of the forming die 1.

As shown in fig. 1, the pressure-receiving portion 6 is a circular ring body surrounding the outer surface of the forming die 1, the end surface is exposed at the parting surface, and the parting surface of the forming die 1 is smooth and has no protrusion. When the upper die and the lower die are closed, the two corresponding pressure-bearing parts 6 are mutually collided and attached to form a complete closed circular ring, and the impact force is shared by the forming dies 1 so as to weaken the collision of the forming dies 1.

In one embodiment, a plate insert 7 is mounted to the bottom of body section 22, and plate insert 7 closes body section 22. The die cavity 2 is communicated up and down, the shape is simple, the cutting and forming can be conveniently carried out on the machine tool machining, a complex control program is not required to be set, then the proper plate insert 7 is installed at the bottom of the bottle body section 22, the final die cavity 2 is obtained, the manufacturing is convenient, and the adjustment of the size of the bottom of the die cavity 2 by workers is convenient.
