[0001] The utility model relates to the technical field of glass bottle blowing molds, in particular to a glass bottle blowing mold. Background Art

[0002] Glass bottles are widely used in packaging applications closely related to people's lives, such as food, medicine, beverages, and cosmetics, due to their hygienic, aesthetically pleasing appearance, reliable sealing, and excellent chemical stability, resisting chemical reactions with their contents. They are the optimal packaging material. However, high-quality and efficient production of glass bottles requires a good mold (the mechanical forming of individual glass bottles is performed in a mold with a precisely shaped inner cavity). The mold's material, structure, machining accuracy, and maintenance are closely related.

[0003] For example, a glass bottle blowing mold with the announcement number CN220597300U includes a base, wherein a double-headed screw is rotatably mounted inside the base through a rotating cavity, a motor connected to the double-headed screw is fixedly mounted on the outer wall of the base, and two movable sleeves are provided on the outer wall of the double-headed screw through a threaded sleeve of a limiting mechanism. The upper end surfaces of the two movable sleeves are connected to a connecting plate through a connecting mechanism, and the inner walls of the two connecting plates are each provided with a slot, and a slider is slidably mounted inside the two slots. The outer walls of the two sliders are fixedly connected to the mold. The device is provided with components such as a support rod, a support plate, and a buffer pad. Through the cooperation of the support rod and the support plate, the formed glass bottle will fall into the gap between the two molds onto the upper surface of the support plate, thereby preventing the glass bottle from falling continuously. The buffer pad made of foam material installed on the upper surface of the support plate can cushion the fall of the glass bottle, thereby preventing the glass bottle from breaking.

[0004] The above patent can cushion the falling glass bottles to prevent them from breaking, but the fixation and clamping of the two molds is unstable, making it difficult to quickly remove the glass bottles after blowing, and demoulding is inconvenient, resulting in low efficiency when blowing glass.

[0005] So we proposed a glass bottle blowing mold to solve the problems raised above. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figure 1 - Figure 3A glass bottle blowing mold comprises a fixed frame 1 and an electric push rod 3 fixedly installed at the lower end of the upper wall of the fixed frame 1, a mold assembly 4 is installed at the lower end of the electric push rod 3, a fixed block 2 is fixedly installed on the side of the fixed frame 1, inclined plates 21 are fixedly installed on both side walls of the upper end of the fixed block 2, a connecting plate 23 is fixedly installed between the two inclined plates 21, and guide rails 24 are fixedly installed on the connecting plate 23, the mold assembly 4 comprises a mold 1 41 fixedly installed at the output end of the electric push rod 3, a slide groove 12 is provided on the upper and lower walls of the fixed frame 1, a telescopic rod 13 is slidably connected in the slide groove 12, a mold 2 42 is fixedly installed at the lower end of the telescopic rod 13, and a fixed rod 48 is fixedly installed on both side walls of the mold 2 42, and the fixed rod 48 is slidably connected in the guide rail 24.

[0023] In this embodiment, when blowing a glass bottle, the heated glass raw material to be blown is first clamped and placed between the mold 1 41 and the mold 2 42 through the openings at the upper ends of the mold 1 41 and the mold 2 42. At this time, the electric push rod 3 can be started, and the electric push rod 3 starts its output end to drive the mold 1 41 to move downward, and the mold 2 42 and the mold 1 41 are fit together and moved downward to the fixed block 2 at the lower end, and slide into the cavity formed by the inclined plate 21 and the connecting plate 23. The relatively fixed clamping effect between the mold 1 41 and the mold 2 42 is automatically completed on the fixed block 2, and the mold 2 42 moves downward. When blowing is completed, when mold 1 41 and mold 2 42 are moved upward, mold 2 42 and mold 1 41 will automatically separate. When the glass bottle blowing mold is used to blow the glass bottle, the molds can be fixed and clamped together, and after blowing is completed, mold 1 41 and mold 2 42 can be separated by moving mold 1 41 and mold 2 42 upward, so that the finished glass bottle can be taken out.

[0024] Example 2: This example is an improvement made on the basis of Example 1. For details, please refer to Figure 2 - Figure 4 The inner walls of both sides of mold 1 41 are provided with connecting grooves 43, and connecting rods 44 are slidably connected in the connecting grooves 43. One end of the connecting rod 44 is fixedly connected to the side wall of mold 2 42, and the connection between mold 1 41 and mold 2 42 is completed through the connecting rod 44.

[0025] A pair of telescopic rods 46 are fixedly mounted on the upper and lower ends of the side walls of the second mold 42 . A second slide groove 22 is provided on both sides of one of the inclined plates 21 , and the telescopic rods 46 are slidably connected in the second slide groove 22 .

[0026] A sliding groove 3 11 is formed on the side wall of the fixed frame 1 , and a movable plate 45 is slidably connected in the sliding groove 3 11 .

[0027] One end of the telescopic rod 46 is fixedly connected to the side wall of the movable plate 45, and a number of springs 47 are fixedly installed between the side wall of the movable plate 45 and the side wall of the mold 2 42. The springs 47 are fixedly installed inside the telescopic rod 46. When the mold 2 42 is not subject to external force, the spring 47 can pull it toward the movable plate 45 until the two molds are completely separated.

[0028] The mold 1 41 and the mold 2 42 are slidably connected in a cavity formed between the inclined plate 21 and the connecting plate 23 , and the mold 1 41 and the mold 2 42 can be clamped and fixed by the inclined plate 21 and the connecting plate 23 .

[0029] In this embodiment: after the heated and softened glass raw material is clamped and fixed at the upper mouth of the mold 1 41, the electric push rod 3 can be started to push the mold 1 41 downward. When the mold 1 41 moves downward, the telescopic rod 13 is driven to slide and stretch along the slide groove 12. When the telescopic rod 13 moves, it drives the lower end of the mold 2 42 to slide obliquely downward along the guide rail 24 through the fixed rod 48. At this time, the side telescopic rod 2 46 and the spring 47 inside it are stretched under the movement of the mold 2 42, and at the same time, the movable plate 45 is driven to slide downward along the slide groove 3 11. In the process of the electric push rod 3 pushing the mold 1 41 downward, the mold 2 42 gradually approaches and merges with the mold 1 41, and continues to push downward. Push mold 1 41 and mold 2 42 into the cavity formed by the inclined plate 21 and the connecting plate 23, and automatically complete the fixed clamping of mold 1 41 and mold 2 42. After blowing is completed, mold 1 41 is pulled up to the initial position again by the electric push rod 3. When the electric push rod 3 pulls mold 1 41, it drives mold 2 42 to slide upward along the guide rail 24, and under the action of the spring 47, mold 2 42 is pulled to a position away from mold 1 41. At this time, the blown glass bottle can be taken out. The device can then complete the merging and separation of mold 1 41 and mold 2 42 by pushing out and recovering the electric push rod 3. The operation is simple, the fixing and clamping effect is good, and the separation of the glass bottles is also easy.
