Description

Technical Field

[0001] This utility model relates to the field of glass bottle tooling mold technology, and in particular to a tooling mold for embossing the inner wall of a glass bottle. Background Technology

[0002] Press-blown glass is a modern manufacturing technique for producing glass bottles. It combines pressing and blowing processes to efficiently and in large quantities produce glass containers with regular shapes and uniform dimensions. Press-blown glass uses two main types of molds: a pressing mold (prototype) and a blowing mold (forming mold). During operation, a suitable amount of molten glass is placed into the pressing mold. Mechanical pressure is used to press the glass into a preform. The preform is then transferred to a blowing machine, where compressed air is blown into it through a blowpipe, causing the glass preform to expand and adhere to the inner wall of the blowing mold, forming the final bottle shape.

[0003] However, the interiors of bottles made using the above methods are all smooth, making it impossible to form special patterns or text on the inner walls of the bottles. This is not conducive to improving the anti-counterfeiting performance of bottles that require anti-counterfeiting measures. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a tooling mold for embossing the inner wall of a glass bottle.

[0027] like Figures 1 to 4 As shown, this utility model proposes a tooling mold for embossing the inner wall of a glass bottle, including a preliminary mold 2 and a forming mold 1. A tilting cylinder 9 is installed between the preliminary mold 2 and the forming mold 1. It also includes a punch component installed on one side of the preliminary mold 2, comprising a cylinder 8 and a printing punch 3 fixedly mounted on the output shaft of the cylinder 8. The printing punch 3 has raised patterns, designs, or text. First, the patterns, designs, and text required for the target product need to be fabricated on the printing punch 3 required for the production of the printing press. When fabricating the printing punch 3, the depth, width, length, taper, and mold opening angle of the patterns, designs, and text of the target product are designed, and the influence of reheating on the size and style of the embossed patterns, designs, and text is considered. Then, the height, taper, and shape of the printing punch 3 are adjusted to meet the production process requirements of pressure blow molding or blow molding.

[0028] The top of the initial mold 2 is equipped with a plug drive assembly, on which a plug 4 is fixedly installed. During operation, the material drips into the mold cavity of the initial mold 2. The plug 4 is moved above the initial mold 2 by the plug drive assembly and seals the top opening of the initial mold 2. At the same time as the plug 4 seals, the printing punch 3 is driven by the cylinder 8, causing the printing punch 3 to move upward. The printing punch 3 punches the exit part and the prototype, and at this time, the required pattern, design, text and other shapes are formed on the inner wall of the prototype.

[0029] Furthermore, the initial mold 2 is equipped with a die 5, and a die clamp 7 is fixedly installed on the tilting cylinder 9. An air blowing mechanism is fixedly installed on the forming mold 1, and an air blowing head 6 is fixedly installed on the air blowing mechanism. Then the prototype is clamped by the die clamp 7, and the tilting cylinder 9 drives the prototype to rotate 180° into the forming mold 1 for reheating and stretching. Then the air blowing head 6 is pressed down, and air is blown into the bottle through the air blowing head 6. The prototype is finally formed in the forming mold 1. The formed bottle is transferred to the stop plate for shaping and cooling by a clamping device, and then transferred to the conveyor belt by a bottle pulling machine. Finally, it is sent into the high-temperature annealing furnace by a bottle pusher to eliminate stress.

[0030] In this embodiment, the printing punch 3 includes a base 301 and a top seat 302 detachably mounted on the base 301. A printing plate 303 with raised patterns on its surface is detachably mounted at the connection between the base 301 and the top seat 302. When producing different batches of bottles, the patterns inside the bottles will also change. By setting the required patterns on the printing plate 303, when changing the patterns, only the printing plate 303 needs to be replaced, eliminating the need to produce a separate printing punch 3 with different patterns, thereby effectively reducing production costs. The base 301 is equipped with an anti-loosening mechanism to prevent eccentricity caused by repeated disassembly and reassembly of the base 301 and the top seat 302. When replacing the printing plate 303, it is necessary to disassemble the top seat 302 and the base 301. After the base 301 and the top seat 302 are disassembled multiple times, the connection may wear out, and the top seat 302 and the base 301 may become loose. This can lead to eccentricity between the top seat 302 and the base 301, resulting in a reduced stamping effect on the glass droplets. The centering and anti-loosening mechanism can prevent this problem from occurring.

[0031] The top seat 302 is fixedly mounted with a first connecting rod 304. The base 301 has a connecting hole for accommodating the first connecting rod 304. The bottom of the first connecting rod 304 has a thread 305, and a nut 306 is threaded onto the thread 305. When disassembling the top seat 302 and the base 301, rotating the nut 306 will separate the nut 306 from the thread 305, allowing the first connecting rod 304 to be pulled out of the connecting hole. Since the inner diameter of the connecting hole is larger than the outer diameter of the first connecting rod 304, it is easier to pull out and insert the first connecting rod 304, preventing friction between the first connecting rod 304 and the connecting hole, and thus preventing wear on the first connecting rod 304 during insertion and removal.

[0032] Furthermore, the anti-loosening mechanism includes drive rods 307 slidably mounted on both sides of the base 301, lifting rods 308 slidably mounted on both sides of the base 301, a second connecting rod 309 fixedly mounted between the lifting rods 308 and the drive rods 307, drive blocks 310 slidably mounted on both sides of the base 301, a round rod 314 fixedly mounted between the two drive blocks 310 on the same side, the lifting rods 308 fixedly connected to the drive blocks 310 at the bottom, a connecting rod 311 rotatably mounted on the drive blocks 310, two sliding rods 312 slidably mounted on both sides of the base 301, the sliding rods 312 and the connecting rods 311 correspond one-to-one and are rotatably connected, and an arc plate 313 is fixedly mounted on the sliding rods 312. When connecting the top seat 302, it needs to be engaged by the nut 306 and the thread 305. At this time, the nut 306 will squeeze the drive rod 307, causing the drive rod 307 to drive the lifting rod 308 to rise. The rising lifting rod 308 will drive multiple drive blocks 310 to rise synchronously. The rising drive blocks 310 will drive the connecting rod 311 to rotate. The rotating connecting rod 311 will push the slide rod 312 to move the arc plate 313, causing the arc plate 313 to squeeze the first connecting rod 304, so that the first connecting rod 304 and the connecting hole are kept in a coaxial position, thereby enabling the top seat 302 and the base 301 to maintain coaxiality.

[0033] When the top seat 302 is disassembled, the nut 306 is removed, and the arc plate 313 will loosen, which can prevent the first connecting rod 304 from wearing. This can effectively prevent the first connecting rod 304 from wearing during repeated disassembly and installation, and effectively improve the service life of the top seat 302 and the base 301.

[0034] The inner diameter of the arc-shaped plate 313 is opposite to the outer diameter of the first connecting rod 304, and the arc-shaped plate 313 is made of rubber. This gives the arc-shaped plate 313 a certain degree of elasticity, which can provide stronger wrapping of the first connecting rod 304 and provide stronger friction to the first connecting rod 304.

[0035] The working principle of this embodiment is as follows: During operation, the material drips into the cavity of the initial mold 2. The end cap 4 is moved above the initial mold 2 by the end cap drive assembly and seals the upper opening of the initial mold 2. At the same time as the end cap 4 seals, the printing punch 3 is driven by the cylinder 8 to move upward. The printing punch 3 punches the exit part and the prototype, and at this time, the required pattern, texture, text and other shapes are achieved on the inner wall of the prototype. Then the prototype is clamped by the die clamp 7 and rotated 180° into the forming mold 1 by the flipping cylinder 9 for reheating and stretching of the prototype. Then the blowing head 6 is pressed down and blows air into the bottle through the blowing head 6. The prototype is finally formed in the forming mold 1. The formed bottle is transferred to the stop plate for shaping and cooling by the clamp transfer device, and then transferred to the conveyor belt by the bottle puller. It is then sent to the high-temperature annealing furnace by the bottle pusher to eliminate stress.

[0036] When replacing the printing plate 303, rotating the nut 306 will separate the nut 306 from the thread 305, allowing the first connecting rod 304 to be pulled out of the connecting hole, thus replacing the printing plate 303. Then, tighten the nut 306 again. During this process, the nut 306 will press against the drive rod 307, causing the drive rod 307 to lift the lifting rod 308. The rising lifting rod 308 will then drive multiple drive blocks 310 to rise synchronously. The rising drive blocks 310 will then drive the connecting rod 311 to rotate. The rotating connecting rod 311 will push the slide rod 312 to move the arc plate 313, causing the arc plate 313 to press against the first connecting rod 304, keeping the first connecting rod 304 coaxial with the connecting hole. This ensures that the top seat 302 and the base 301 remain coaxial.

[0037] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
