Description

Technical Field

[0001] This invention relates to the field of glassware processing technology, specifically to an energy-saving glassware blowing molding apparatus. Background Technology

[0002] With the rapid development of the glass manufacturing industry, energy-saving glassware has seen a continuous increase in market demand due to its advantages such as good light transmission, heat preservation and energy saving, environmental protection and durability. In the glassware processing and production process, blow forming is a key process that determines the appearance and forming quality of the glassware. Its processing and forming effect directly affects the finished product qualification rate and performance of the glassware. Therefore, it is necessary to use energy-saving blow forming equipment with high adaptability and strong stability to complete the blow forming operation of glassware.

[0003] However, existing blow molding equipment mostly uses a simple rigid push demolding method during use. The demolding process has a large impact force, which can easily cause strong pulling and friction with the inner wall of the mold, making it very easy for glassware to crack and deform, thus affecting the yield of finished products. Summary of the Invention

[0004] The purpose of this invention is to provide an energy-saving glass blowing molding device. By setting up an auxiliary demolding part, it solves the problem that existing glass blowing molding devices often use a simple hard push demolding method during use. The demolding process has a large impact force, which easily causes strong pulling friction with the inner wall of the mold, which can easily cause the glassware to crack and deform, thus affecting the yield of finished products.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to an energy-saving glassware blowing molding device, comprising a support frame, and further comprising: two auxiliary demolding sections, each mounted on the support frame; two demolding sections, each mounted on one of the two auxiliary demolding sections; a mold closing section mounted on the support frame; each auxiliary demolding section includes a mold assembly mounted on the support frame; and a vibration assembly mounted on the mold assembly. The mold assembly includes a blow molding die mounted on the support frame, the blow molding die having a circular groove, a circular plate rotatably connected within the circular groove, a circular rod penetrating through the circular plate, the side of the circular rod away from the circular plate extending outside the blow molding die, the circular rod slidably connected to the circular plate, the side of the circular rod away from the circular plate being fixedly connected to the support frame, a threaded groove on the outer wall of the circular rod, a transmission block disposed within the threaded groove, and the transmission block being fixedly connected to the inner wall of the circular plate; the two auxiliary demolding sections and the two demolding sections are mirror images of each other, and the circular rod is in contact with the circular plate.

[0006] Furthermore, the demolding part includes an ejector pin assembly mounted on the blow mold; and an elastic component disposed within a circular groove.

[0007] Furthermore, the mold closing part includes a guide assembly mounted on a support frame; and a drive assembly disposed on the support frame.

[0008] Furthermore, the vibration assembly includes several hollow cylindrical rods fixedly connected to a circular plate. A circular limiting plate is slidably connected within each of the hollow cylindrical rods. A sliding rod is fixedly connected to the side of each circular limiting plate away from the circular plate. A protrusion is fixedly connected to the side of each sliding rod away from the circular plate. Several extrusion blocks are fixedly connected to the inner wall of the circular groove. An elastic element is provided within each of the hollow cylindrical rods. Three hollow cylindrical rods and three extrusion blocks are provided, arranged in a circumferential array. The three circular limiting plates are located at the middle of the three hollow cylindrical rods. The three protrusions are in contact with the inner wall of the circular groove. The elastic element includes a spring 1 disposed within a hollow cylindrical rod. The side of the spring 1 closest to the circular limiting plate is fixedly connected to the circular limiting plate, and the side of the spring 1 away from the circular limiting plate is fixedly connected to the hollow cylindrical rod. The spring 1 is in a slightly compressed state.

[0009] Furthermore, the ejector pin assembly includes a push plate disposed within the blow molding die, a push rod fixedly connected to the side of the push plate near the blow molding die, the push rod extending into a circular groove on the side away from the push plate, the push rod being slidably connected to the blow molding die, and a fixing plate fixedly connected to the side of the push rod away from the push plate; the fixing plate is located within the circular groove.

[0010] Furthermore, the elastic component includes a second spring sleeved on the outer wall of the top rod, the side of the second spring near the fixed plate being fixedly connected to the fixed plate, and the side of the second spring away from the fixed plate being fixedly connected to the blow molding die.

[0011] Furthermore, the guide assembly includes two inverted U-shaped brackets fixedly connected to the top of the support frame, two guide rods fixedly connected between the two inverted U-shaped brackets, the two guide rods passing through the two blow molding dies, and the two guide rods slidably connected to the two blow molding dies; the two guide rods are arranged in parallel.

[0012] Furthermore, the drive assembly includes a bidirectional threaded rod rotatably connected between the left and right inner walls of the support frame. The right side of the bidirectional threaded rod extends outside the support frame. Two rectangular blocks are fixedly connected to the bottom of each of the two blow molds. The bidirectional threaded rod passes through the two rectangular blocks and is threadedly connected to the two rectangular blocks. A motor is fixedly connected to the bottom inner wall of the support frame. The output shaft of the motor is fixedly connected to the bidirectional threaded rod via a coupling. Protective components are provided on the bidirectional threaded rod. The two rectangular blocks are located on the threads on both sides of the bidirectional threaded rod. The protective components include several telescopic protective sleeves sleeved on the outer wall of the bidirectional threaded rod. The sides of the two telescopic protective sleeves located on the left and right sides that are far apart from each other are fixedly connected to the support frame. The sides of the two telescopic protective sleeves located on the left and right sides that are close to each other are fixedly connected to the two rectangular blocks. Three telescopic protective sleeves are provided, and the two ends of the telescopic protective sleeve located in the middle are fixedly connected to the two rectangular blocks respectively.

[0013] The present invention has the following beneficial effects: (1) By setting an auxiliary demolding part, the motor drives the bidirectional threaded rod to rotate in the opposite direction during demolding, driving the two blow molds to move away from each other. While the mold slides along the circular rod, the circular plate rotates in the circular groove by means of the transmission cooperation between the threaded groove on the circular rod and the transmission block, thereby making the hollow cylindrical rod perform circumferential motion, and driving the sliding rod and protrusion to move synchronously through the circular limiting plate. When the protrusion passes the extrusion block, it is forced to retreat and compress the first spring. After it leaves the extrusion block, the first spring rebounds and resets. The impact generated by the reset causes the blow mold to form a low-frequency vibration, thereby realizing the vibration demolding of the glassware. The low-frequency micro-vibration is generated by the spring energy storage reset, which gently loosens the adhesion between the product and the inner wall of the mold, avoiding the cracking and deformation of the glassware caused by hard demolding, and improving the yield of finished products. (2) By setting up a demolding part, the circular rod abuts against the fixed plate during the mold opening and movement process. The blow molding mold continues to slide relative to the circular rod, which drives the fixed plate to push the ejector rod to move on the mold. At the same time, the spring is compressed to store energy. The ejector rod then drives the push plate to extend out of the mold and push the molded glassware outward. It works in conjunction with the aforementioned vibration demolding structure. The dual effect weakens the adhesion between the product and the mold, making demolding smoother and less prone to jamming. This further improves the integrity of the finished product and the overall demolding efficiency. (3) By setting up a mold closing part, the glassware raw material is placed between two sets of blow molding molds during operation. The motor drives the bidirectional threaded rod to rotate. With the help of the fixed connection between the rectangular block and the blow molding mold, and the sliding limit of the blow molding mold on the guide rod, the bidirectional threaded rod drives the two sets of blow molding molds to slide towards each other along the guide rod through the rectangular block to complete the mold closing and wrapping of the raw material. At the same time, the telescopic protective sleeve deforms synchronously with the movement of the rectangular block to form a shielding protection for the thread groove of the bidirectional threaded rod, so as to realize the smooth facing mold closing of the blow molding mold. The mold closing process runs smoothly and the alignment is reliable. It can stably wrap the glass raw material. The telescopic protective sleeve effectively blocks dust, glass fragments and other impurities from entering the threaded part and avoids thread wear and jamming.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-8 As shown, the present invention is an energy-saving glass blowing molding device for glassware processing, including a support frame 111, and further including: two auxiliary demolding parts 2, both of which are mounted on the support frame 111; two demolding parts 3, each mounted on one of the two auxiliary demolding parts 2; and a mold closing part 4, which is mounted on the support frame 111.

[0020] The auxiliary demolding unit 2 includes a mold assembly 21, which is mounted on a support frame 111; and a vibration assembly 22, which is mounted on the mold assembly 21. The mold assembly 21 includes a blow molding die 211 mounted on the support frame 111. The blow molding die 211 has a circular groove 212.

The circular rod 214 is fixedly connected to the support frame 111 on the side away from the circular plate 213. A threaded groove 215 is formed on the outer wall of the circular rod 214, and a transmission block 216 is disposed within the threaded groove 215. The transmission block 216 is fixedly connected to the inner wall of the circular plate 213. The two auxiliary demolding parts 2 and the two demolding parts 3 are mirror images of each other.

[0021] The demolding section 3 includes an ejector pin assembly 31, which is mounted on the blow mold 211; and an elastic component 32, which is disposed in a circular groove 212. The ejector pin assembly 31 includes a push plate 311 disposed in the blow mold 211. A push rod 312 is fixedly connected to the side of the push plate 311 near the blow mold 211. The side of the push rod 312 away from the push plate 311 extends into the circular groove 212. The push rod 312 is slidably connected to the blow mold 211.

By setting the demolding part 3, the adhesion between the product and the mold is weakened by the dual effect, the demolding is smoother, and it is not easy for the mold to get stuck, which further improves the integrity of the finished product and the overall demolding efficiency.

[0022] The mold clamping section 4 includes a guide assembly 41 mounted on the support frame 111; and a drive assembly 42 mounted on the support frame 111. The guide assembly 41 includes two inverted U-shaped brackets 411 fixedly connected to the top of the support frame 111, and two guide rods 412 fixedly connected between the two inverted U-shaped brackets 411. The two guide rods 412 pass through the two blow molds 211 and are slidably connected to the two blow molds 211. The two guide rods 412 are arranged in parallel. The drive assembly 42 includes a bidirectional threaded rod 421 rotatably connected between the left and right inner walls of the support frame 111. The right side of the bidirectional threaded rod 421 extends outside the support frame 111. Two rectangular blocks 422 are fixedly connected to the bottom of each of the two blow molds 211. The bidirectional threaded rod 421 passes through the two rectangular blocks 422 and is threadedly connected to the two rectangular blocks 422. A motor is fixedly connected to the bottom inner wall of the support frame 111. 423, the output shaft of motor 423 is fixedly connected to bidirectional threaded rod 421 via coupling. The bidirectional threaded rod 421 is equipped with protective components. Two rectangular blocks 422 are located on the threads on both sides of the bidirectional threaded rod 421. The protective components include several telescopic protective sleeves 424 sleeved on the outer wall of the bidirectional threaded rod 421. The two telescopic protective sleeves 424 located on the left and right sides are fixedly connected to the support frame 111 on the side away from each other. The two telescopic protective sleeves 424 located on the left and right sides are fixedly connected to the two rectangular blocks 422 on the side close to each other. There are three telescopic protective sleeves 424. The two ends of the telescopic protective sleeve 424 located in the middle are fixedly connected to the two rectangular blocks 422 respectively. By setting the mold closing part 4, the blow molding mold 211 can be smoothly aligned and closed. The mold closing process is smooth and the alignment is reliable. It can stably wrap the glass raw material. The telescopic protective sleeves 424 effectively block dust, glass fragments and other impurities from entering the threaded part and avoid thread wear and jamming.

[0023] It should be noted that the motor 423 in this application can be automatically controlled by using a program set in the control panel and inputting relevant parameters as needed. The setting of this control method can be achieved using existing technologies, such as PLC.

[0024] In use, the glassware material is placed between two blow molding molds 211, and the motor 423 is started. The motor 423 drives the bidirectional threaded rod 421 to rotate. Since the two rectangular blocks 422 are fixedly connected to the two blow molding molds 211 respectively, and the two blow molding molds 211 are slidably connected to the two guide rods 412, the bidirectional threaded rod 421 drives the two blow molding molds 211 to slide on the two guide rods 412 through the two rectangular blocks 422 and move closer to each other. During this process, the three telescopic protective sleeves 424 deform with the movement of the two rectangular blocks 422 to protect the threaded groove of the bidirectional threaded rod 421. At this time, the two blow molding molds 211 are closed and the glassware material is wrapped. The glassware raw material was then blow-molded using an air blowing device; During demolding, motor 423 is started, and motor 423 drives bidirectional threaded rod 421 to rotate in the reverse direction, causing the two blow molding dies 211 to move away from each other. When the two blow molding dies 211 move away from each other, the blow molding dies 211 slide on circular rod 214. With the cooperation of threaded groove 215 on circular rod 214 and transmission block 216 in circular plate 213, the circular plate 213 is pushed to rotate in circular groove 212. Circular plate 213 drives hollow cylindrical rod 221 to perform circumferential motion. Hollow cylindrical rod 221 drives protrusion 224 on slide rod 223 to move through circular limiting plate 222. When protrusion 224 contacts extrusion block 225, protrusion 224 is squeezed by extrusion block 225, causing protrusion 224 to move away from extrusion block 225. The protrusion 224 pushes the slide bar 223 to move into the hollow cylindrical rod 221. The slide bar 223 pushes the circular limiting plate 222 to move and compresses the spring 226, causing the spring 226 to deform and generate elastic force. When the protrusion 224 passes the extrusion block 225, the extrusion force on the spring 226 disappears and the elastic force is released. The elastic force acts on the circular limiting plate 222. The circular limiting plate 222 pushes the protrusion 224 to quickly reset through the slide bar 223. Since the circular limiting plate 222 is half inside the hollow cylindrical rod 221 and the spring 226 is in a slightly compressed state, the protrusion 224 will impact the blow mold 211 when it resets quickly, and cause the blow mold 211 to generate low-frequency vibration, thereby performing vibration demolding. When the circular rod 214 contacts the fixed plate 313, the blow molding mold 211 continues to move on the circular rod 214. The circular rod 214 pushes the ejector rod 312 to move on the blow molding mold 211 through the fixed plate 313. During this process, the fixed plate 313 squeezes the second spring 321, causing the second spring 321 to deform and generate elastic force. At this time, the ejector rod 312 pushes the push plate 311 out of the blow molding mold 211, thereby pushing out the formed glassware. This, combined with vibration demolding, improves demolding efficiency.
