Description

Technical Field

[0001] This invention relates to the field of liquid container manufacturing technology, specifically to an antibacterial drinking cup-type lid sealing container, molding equipment, and its preparation process. Background Technology

[0002] With rising consumer awareness and a growing demand for environmentally friendly products, storage containers for alcoholic beverages and other liquids are evolving towards multifunctionality, integration, portability, hygiene, and environmental friendliness. Currently, most storage containers on the market are designed with single functions, with storage containers, dispensing devices, and drinking glasses operating independently. This leads to problems such as fragmented storage, inconvenience in carrying, and easy loss of accessories. In public dining and outdoor gatherings, the repeated use of shared, individual drinking containers can easily cause cross-contamination, posing hygiene and safety risks. While disposable drinking containers are convenient, they cannot be reused, resulting in resource waste and environmental burden.

[0003] Although some integrated beverage storage containers have appeared on the market, they still have many technical defects: for example, the lid does not have a drinking function and does not achieve multiple uses; the overall antibacterial and environmental protection are poor; the lid and bottle are only a single snap-fit ​​structure, lacking a sealing structure, and the liquid in the bottle is easy to evaporate and leak; at the same time, there is no universal compatibility structure for bottles of different materials and capacities, resulting in high industrial mass production costs.

[0004] Meanwhile, the current manufacturing process for antibacterial glass drinking cup lids primarily employs traditional integral mold blowing molding. When opening the mold using this method, the formed glass container easily adheres to the inner wall of the mold, making it highly susceptible to scratches, bumps, and even breakage during removal, resulting in a high average breakage rate in the industry. Furthermore, for thin-walled, irregularly shaped conical sealing structures like drinking cup lids, traditional processes struggle to control wall thickness uniformity, leading to issues such as eccentricity and excessive thickness differences causing insufficient strength. Traditional equipment requires complete disassembly of both the fixed and moving molds for mold changes, resulting in lengthy changes and poor production continuity. Moreover, the mold opening, removal, and resetting processes are cumbersome, and the capacity of a single machine is insufficient to meet the demands of large-scale mass production. Summary of the Invention

[0005] To address the problems in the prior art, the present invention provides an antibacterial drinking cup lid sealing container, molding equipment, and manufacturing process thereof. The present invention is achieved through the following technical solutions.

[0006] An antibacterial drinking cup-type sealed container, comprising: The bottle / cup body is a liquid storage container with an open top. A dispensing cup opening is formed at the top of the bottle / cup body. The inner wall of the dispensing cup opening is a conical bottle mouth. A guide port is also provided on the outer side of the dispensing cup opening. A drinking cup-shaped lid, wherein the drinking cup-shaped lid is a cup-shaped structure with an open bottom, and is detachably fitted onto the top of the bottle / cup body; The outer wall of the drinking cup lid has a conical mating surface that matches the conical bottle opening; The conical mating surface is also fitted with one or more food-grade sealing rings to form a multi-layer seal with the inner wall of the conical bottle opening.

[0007] Preferably, the surface of the conical mating surface is provided with at least two equidistant limiting grooves along the axial direction, and the food-grade sealing ring is embedded in the inner side of the limiting groove; The bottom of the bottle / cup body is provided with a flat, circular support surface, which allows the bottle / cup body to be placed upright independently. The conical bottle opening has an outer ring of outward-curving edge, which is used to limit the position of the drinking cup-type lid when it is closed, and to prevent liquid from overflowing during secondary filling.

[0008] Both the bottle / cup body and the drinking cup lid are made of antibacterial high borosilicate glass. The antibacterial high borosilicate glass is based on a high borosilicate glass matrix, and antibacterial components are introduced through melt doping or silver ion exchange processes. This results in the uniform distribution of inorganic antibacterial components such as silver ions, zinc ions, or copper ions on the surface or inside of the antibacterial high borosilicate glass. Furthermore, the outer surfaces of the bottle / cup body and the drinking cup lid made of the antibacterial high borosilicate glass are dense and non-porous.

[0009] A molding device for an antibacterial drinking cup lid sealing container includes a base, an mounting platform assembly on the base, and a lifting drive assembly fixedly connected to the base. A molding mold assembly is mounted on the mounting platform assembly, and an air blowing molding assembly is mounted on the molding mold assembly. A mold closing and locking drive assembly is mounted on one side of the molding mold assembly. The mounting platform assembly includes a mounting base plate and limiting and positioning blocks disposed on both sides of the mounting base plate, and a positioning guide strip is connected to the upper side of the mounting base plate. The molding die assembly includes a fixed die component and a fixed die base fixedly connected to the lower end of the fixed die component. A container-bearing intermediate die is provided on the lower side of the fixed die component, and a movable die component is provided on the other side of the container-bearing intermediate die component. A movable die base is fixedly connected to the lower end of the movable die component. The air-blowing molding assembly includes a quick-release connector and a core body tube connected to one end of the quick-release connector. The other end of the core body tube is connected to an air-blowing end. The core body tube is provided with a connecting air passage. The air-blowing end is provided with an air-blowing port. The upper side of the core body tube is provided with a liquid injection port, and a liquid injection pipe is connected to the liquid injection port.

[0010] Preferably, the lifting drive assembly includes a lifting mounting frame and a lifting sliding plate disposed on the lifting mounting frame, wherein one end of the lifting sliding plate is connected to a lifting drive screw and the other end is connected to a lifting limit seat, and a venting connection pipe is installed on the lifting sliding plate.

[0011] Preferably, the mold clamping and locking drive assembly includes a drive cylinder and a fixed mold fixing seat fixedly connected to the upper side of the drive cylinder. A telescopic rod is provided on one side of the drive cylinder, and a connecting slider is fixedly connected to the other end of the telescopic rod. A moving mold fixing seat is connected to the connecting slider.

[0012] Preferably, the fixed mold component includes a fixed mold body and a molding cavity formed in the fixed mold body, and cooling components are uniformly arranged on the outer side of the molding cavity.

[0013] Preferably, the container-carrying intermediate mold includes an intermediate mold base and engagement guide grooves formed on both sides of the intermediate mold base, and an engagement positioning groove is provided at one end of the engagement guide groove, and an opening limiting groove is provided on one side of the intermediate mold base.

[0014] Preferably, the moving mold base includes a moving mold base body and a clearance groove formed on the moving mold base body, and a guide rail groove is formed on the lower side of the moving mold base body. Elastic locking arms are connected to both sides of the interior of the moving mold base body, and an elastic locking block is connected to one end of the elastic locking arm. The elastic block is made of elastic material and cooperates with the engagement guide groove, and finally engages in the engagement positioning groove. The opening end of the engagement guide groove has a guide cut surface.

[0015] A manufacturing process for an antibacterial drinking cup lid sealing container includes the following steps: S1 mold pre-assembly and positioning: The fixed mold part and the moving mold part are positioned on the mounting base plate by positioning guide strips. The container carrying middle mold is placed between the fixed mold part and the moving mold part. The fixed mold base is fixedly connected to the fixed mold fixed base and the moving mold base is fixedly connected to the moving mold fixed base by bolts. The container carrying middle mold is initially laterally limited by the limiting positioning block. S2 Mold Closure and Locking: The start-up drive cylinder drives the telescopic rod to move the connecting slider, moving mold fixing seat and moving mold part towards the fixed mold part. The elastic block slides into the guide surface of the engagement guide groove and engages in the engagement positioning groove, driving the container bearing middle mold to move synchronously until the end faces of the fixed mold part, the container bearing middle mold and the moving mold part are tightly fitted to form a complete sealed molding cavity. The drive cylinder maintains a constant pressure of 0.5~0.8MPa to complete the mold closure and locking. S3 Core Alignment: Start the lifting drive screw to drive the lifting sliding plate to move vertically downward along the lifting mounting frame. The lifting limit seat restricts the downward limit position of the lifting sliding plate, so that the air blowing molding component, which is detachably connected to the air connection pipe, is accurately inserted into the center position of the molding cavity, and the coaxiality error is controlled within 0.05mm. S4 High Temperature Injection: Molten antibacterial glass liquid at a temperature of 1100-1200℃ is injected into the molding cavity through the injection pipe. The antibacterial glass liquid is uniformly mixed with antibacterial high borosilicate glass solution and antibacterial components. The antibacterial glass liquid flows into the complete molding cavity until it is full, then the injection is stopped and the injection port of the injection pipe is sealed. S5 Surface Pre-cooling: After the filling is completed, let it stand for 3 to 5 seconds for natural pre-cooling, so that a preliminary hardening layer with a thickness of 0.1 to 0.3 mm is formed on the outer surface of the antibacterial glass liquid, preventing the antibacterial glass liquid from being dispersed by the airflow during the subsequent blowing process; S6 Air Blowing and Shaping: Dry compressed air at a pressure of 0.2 to 0.4 MPa is introduced into the connecting air passage inside the quick-release connector and the core body tube through the air passage interface at the upper end of the air connection pipe. The compressed air is sprayed out through the air blowing ports evenly distributed on the side wall of the air blowing end, so that the antibacterial glass liquid is evenly attached to the inner wall of the molding cavity, forming the initial shape of the container. S7 Cooling and Curing: Maintain compressed air pressure for 5-8 seconds, and at the same time accelerate the heat exchange between the mold and the antibacterial glass liquid through cooling components evenly arranged on the outside of the fixed mold and the moving mold, so that the container as a whole is cooled and cured to below 500°C, avoiding irregular shrinkage and deformation during the cooling process; S8 Step-by-Step Mold Opening: First, the lifting drive screw is activated to drive the lifting sliding plate to move upward, causing the air-blowing molding component to completely detach from the molding cavity; in the initial stage of mold opening, the elastic block is still engaged in the engagement positioning groove, and the moving mold part drives the container-bearing middle mold to move synchronously through the moving mold base. When the container-bearing middle mold moves to the preset position, the limit positioning block is engaged in the mold opening limit slot to rigidly limit the container-bearing middle mold. The drive cylinder continues to drive the moving mold part to move, causing the elastic block of the elastic material to elastically contract and disengage from the engagement guide groove, completing the automatic separation of the container-bearing middle mold and the moving mold part; S9 Part Removal and Mold Change: Remove the container carrier mold containing the formed container from the mounting base plate as a whole and transfer it to the subsequent trimming and annealing processes; replace it with a new container carrier mold and complete the rapid positioning through the limit positioning block and positioning guide strip, and repeat steps S2 to S8 for continuous production.

[0016] The present invention has the following beneficial effects: 1. By adopting a split mold structure, combined with a linkage mechanism of elastic clamping arms and clamping guide grooves and a step-by-step mold opening process, the molded container separates from the fixed mold and moving mold as a whole with the container bearing middle mold during mold opening, avoiding problems such as sticking, scratching and bumping during the mold opening process; at the same time, high-precision core positioning reduces the deviation of product wall thickness, solving the strength defects caused by uneven wall thickness.

[0017] 2. By quickly changing the structure, only the load-bearing middle mold needs to be replaced when changing molds, without disassembling the fixed mold and the moving mold, which greatly shortens the time of a single mold change. Moreover, the part removal and mold change can be carried out in parallel with the next round of mold closing and forming process, which increases the production capacity of a single machine and realizes continuous production.

[0018] 3. By using forced cooling combined with constant pressure blowing shaping process, the flash defects of the product are reduced, the workload of subsequent trimming processes is reduced, and the overall production cost is reduced.

[0019] 4. This antibacterial drinking cup-style lid sealing container allows the bottle / cup body to function as a dispensing and storing container, while the drinking cup-style lid serves as both a wine glass and a sealing cap. It eliminates the need for any shared drinking utensils, completely preventing cross-contamination and addressing hygiene and safety issues at their source. Furthermore, the antibacterial drinking cup-style lid sealing container features multiple layers of food-grade sealing rings that precisely fit the conical bottle neck, significantly improving sealing performance and effectively preventing liquid evaporation and leakage.

[0020] 5. This antibacterial drinking cup-style lid sealing container consists of only two main parts, making it compact and easy to carry; the inner and outer walls are smooth with no dead corners, making it easy to clean and reusable, thus avoiding the waste of disposable wine utensils; at the same time, the drinking cup-style lid sealing container can be universally adapted to the bottle mouth structure size of bottle cups of different materials and capacities, thus facilitating industrial mass production.

[0021] 6. This antibacterial drinking cup-type sealed container, through the use of antibacterial high borosilicate glass for the bottle body and drinking cup-type lid, has a long-lasting and stable antibacterial function, which can effectively inhibit the attachment and reproduction of common harmful microorganisms such as Escherichia coli and Staphylococcus aureus, reduce the risk of cross-contamination, and improve the hygiene and safety of drinking.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] Example 1

[0027] Combination Figures 9-13 As shown, this is the first embodiment of the present invention, which provides an antibacterial drinking cup type lid sealing container, the core of which consists of two main components: the bottle / cup body 1 and the drinking cup type lid 8.

[0028] The bottle / cup body 1 is integrally molded from food-grade glass, with an internal liquid storage chamber 2 having a volume of 100-500ml. The top of the bottle / cup body 1 forms a dispensing spout 3, with a rounded chamfered edge. A guide port 92 is also provided on the outer side of the dispensing spout 3, which serves as a limiting point to facilitate the pouring of liquid from the bottle / cup body 1. The inner wall of the dispensing spout 3 is a conical bottle mouth 4 with a taper of 6°. An annular outward-flaring edge 6 is provided on the outer side of the conical bottle mouth 4. This outward-flaring edge 6 serves both as a limiting structure for pouring liquid from the bottle / cup body 1 and as an auxiliary positioning structure for the drinking cup cap 8, facilitating the insertion of the drinking cup cap 8 into the conical bottle mouth 4. The outward-flaring edge 6 also facilitates secondary filling of liquid, effectively preventing spillage during filling. The bottom of the bottle / cup body 1 has a flat, circular support surface 7, allowing it to stand upright independently.

[0029] The drinking glass-style lid 8 is made of food-grade glass and molded in one piece. The overall structure is an ergonomic cup shape with a rounded, outward-flaring rim. The interior of the cup has a cavity to hold liquid, making it suitable as a dedicated personal wine glass. The outer wall of the drinking glass-style lid 8 has a conical mating surface 9 that perfectly matches the taper of the conical bottle mouth 4.

[0030] The drinking cup-style lid 8 combines sealing and drinking functions, eliminating the need for an additional wine glass, reducing accessories, and making it more convenient to carry and use when dining out.

[0031] Connection and sealing anti-detachment structure: On the conical mating surface 9, two rings of limiting grooves 5 are equidistantly formed along the axial direction. Each of the two limiting grooves 5 is embedded with a food-grade silicone sealing ring 91. When the drinking cup lid 8 is closed with the bottle cup body 1, the two rings of food-grade sealing rings 91 fit tightly against the inner wall of the conical bottle mouth 4, forming two reliable sealing lines to effectively prevent liquid evaporation or leakage.

[0032] The cone-shaped mating surface 9, combined with multiple food-grade sealing rings 91, forms a double-sealing structure, ensuring no leakage even when the container is inverted, shaken, or bumped, making it suitable for travel scenarios.

[0033] Functionality implementation: Wine storage function: When the drinking cup-style lid 8 is closed with the bottle cup body 1, it forms a dedicated, sealed wine storage container for long-term, sealed storage of liquids. As an independent, self-contained device, it completely avoids cross-use by multiple people in scenarios such as food stalls and restaurants with high foot traffic where public cups are not thoroughly disinfected, thus improving drinking hygiene and safety.

[0034] Wine dispensing function: Open the cap 8, hold the bottle cup body 1, and pour the liquid through the dispensing cup opening 3. The bottle cup body 1 then serves as a dedicated personal wine dispenser.

[0035] Drinking function: The dispensed wine is directly collected in the drinking cup-shaped lid 8, which serves as a dedicated personal wine glass.

[0036] Description of antibacterial borosilicate glass: Both the bottle / cup body 1 and the drinking cup lid 8 are made of antibacterial high borosilicate glass. This glass is based on a high borosilicate glass matrix, and antibacterial components are introduced through melt doping or silver ion exchange processes. This allows the inorganic antibacterial components such as silver ions, zinc ions, or copper ions to be evenly distributed on the surface or inside the matrix of the antibacterial high borosilicate glass. While maintaining the glass's original high light transmittance, thermal shock resistance, chemical stability, and food contact safety, it achieves long-lasting and stable antibacterial function.

[0037] The bottle / cup body 1 and the drinking cup lid 8, made of antibacterial high borosilicate glass, have a dense, non-porous outer surface, making them easy to clean and disinfect and less prone to absorbing dirt. The antibacterial components are firmly bonded to the glass substrate, are heat-resistant, wear-resistant, and do not easily fall off. They maintain a stable antibacterial effect even under long-term use and repeated cleaning, effectively inhibiting the attachment and reproduction of common harmful microorganisms such as Escherichia coli and Staphylococcus aureus, reducing the risk of cross-contamination, and improving the hygiene and safety of drinking beverages.

[0038] Furthermore, the antibacterial high borosilicate glass meets the relevant requirements of GB4806.5 food contact glass products and T / CNSAIA004-2023 antibacterial glass cups, with an antibacterial rate of ≥99% against common pathogens. It is suitable for food contact, daily utensils, and health and hygiene liquid containers, representing a functional upgrade in the fields of new materials and health consumption.

At this time, the elastic block 454 slides into the guide section of the engaging guide groove 432 and engages in the engaging positioning groove 433, thereby driving the container-bearing middle mold 43 to move synchronously to the left until the end faces of the fixed mold part 41, the container-bearing middle mold 43 and the moving mold 44 are tightly fitted together to form a complete sealed molding cavity. The drive cylinder 61 maintains pressure to achieve mold closing and locking.

[0047] Simultaneously, the lifting sliding plate 32 is driven to move vertically downward along the lifting mounting frame 31 by the lifting drive screw 33, and the lifting limit seat 35 restricts its downward position, so that the blowing forming component 50, which is detachably connected to the ventilation connecting pipe 34, is precisely matched to the center position of the forming cavity 412 inside the fixed mold part 41 and the moving mold part 44; then, high temperature antibacterial glass liquid is injected into the forming cavity 412 through the liquid injection pipe 57, and the antibacterial glass liquid flows into the forming cavity until the cavity is full.

[0048] After the antibacterial glass liquid is filled, the pouring is stopped and natural pre-cooling is allowed for 3-5 seconds to form a preliminary hardening layer on the surface of the antibacterial glass liquid. Then, compressed air is introduced into the quick-release connector 51 and the connecting vent 54 channel inside the core body tube 52 through the air passage interface at the upper end of the venting connection pipe 34. The compressed air is sprayed out through the air outlet 55 evenly arranged on the side wall of the blowing end 53 to ensure that the airflow acts evenly on the inner wall of the antibacterial glass liquid, so that the antibacterial glass liquid is evenly attached to the inner wall of the cavity to complete the preliminary shaping.

[0049] After the initial shaping is completed, the compressed air pressure is maintained for 5 to 8 seconds. At the same time, the cooling components 413, which are evenly arranged on the outside of the fixed mold part 41 and the moving mold part 44, are used to accelerate the heat dissipation of the mold and the antibacterial glass liquid, so as to complete the complete cooling and shaping of the container and prevent shrinkage and deformation during the cooling process.

[0050] After the shaping is completed, the lifting drive screw 33 drives the lifting sliding plate 32 to move upward, causing the blow molding component 50 to move out of the cavity inside the fixed mold part 41; then the drive cylinder 61 is activated to drive the telescopic rod 63 to move, causing the moving mold part 44, which is fixedly connected to the connecting slider 64 and the moving mold fixing seat 65, to move; at the initial stage of mold opening, because the elastic block 454 is engaged in the engagement positioning groove 433, the moving mold part 44 drives the container carrying middle mold 43 to move synchronously to the right through the moving mold seat 45; when the container carrying middle mold 43 moves to the preset position... The limiting positioning block 22 is inserted into the mold opening limiting slot 434 on the rear side of the intermediate mold base 431 to limit the container-bearing intermediate mold 43; at this time, the drive cylinder 61 continues to drive the moving mold part 44 to move to the right, and the elastic block 454 made of elastic material undergoes elastic contraction under the action of tension, and is disengaged from the engaging guide groove 432, completing the automatic separation of the container-bearing intermediate mold 43 from the moving mold part 44 and the moving mold base 45. At this time, the fixed mold part 41, the container-bearing intermediate mold 43 and the moving mold part 44 are completely separated, and the formed container remains on the intermediate mold base 431.

[0051] At this point, the container-bearing intermediate mold 43 can be directly removed from the mounting base plate 21, and the formed container can be transferred to subsequent trimming, annealing and other processing steps. At the same time, a new container-bearing intermediate mold 43 can be replaced, and it can be repositioned using the positioning block 22. The drive cylinder 61 can be started again to drive the moving mold part 44 to move to the left to close the fixed mold part 41, the container-bearing intermediate mold 43 and the moving mold part 44, and the next round of production can continue.

[0052] Example 3

[0053] Combination Figures 1 to 8 As shown, this is the third embodiment of the present invention, which, based on embodiment 2, further provides a preparation process for an antibacterial drinking cup lid sealing container, including the following steps: S1 Mold Pre-assembly Positioning: Position the fixed mold part 41 and the moving mold part 44 on the mounting base plate 21 using the positioning guide strip 23. Place the container-bearing middle mold 43 between the fixed mold part 41 and the moving mold part 44. Fix the fixed mold base 42 to the fixed mold fixing base 62 and the moving mold base 45 to the moving mold fixing base 65 using bolts. Use the limiting positioning block 22 to initially limit the lateral movement of the container-bearing middle mold 43. S2 Mold Closure and Locking: The start-up drive cylinder 61 drives the telescopic rod 63 to move the connecting slider 64, the moving mold fixing seat 65 and the moving mold part 44 towards the fixed mold part 41. The elastic block 454 slides into the guide section of the engaging guide groove 432 and engages in the engaging positioning groove 433, driving the container carrying middle mold 43 to move synchronously until the end faces of the fixed mold part 41, the container carrying middle mold 43 and the moving mold part 44 are tightly fitted to form a complete sealed molding cavity. The drive cylinder 61 maintains a constant pressure of 0.5~0.8MPa to complete the mold closure and locking. S3 Core Alignment: Start the lifting drive screw 33 to drive the lifting sliding plate 32 to move vertically downward along the lifting mounting frame 31. The lifting limit seat 35 restricts the downward limit position of the lifting sliding plate 32, so that the blowing molding component 50, which is detachably connected to the ventilation connection pipe 34, is accurately inserted into the center position of the molding cavity 412, and the coaxiality error is controlled within 0.05mm. S4 High-temperature injection: Molten antibacterial glass liquid at a temperature of 1100-1200℃ is injected into the forming cavity 412 through the injection pipe 57. The antibacterial glass liquid is a uniform mixture of antibacterial high borosilicate glass solution and antibacterial components. The antibacterial glass liquid flows into the complete forming cavity until it is full, then the injection is stopped and the injection port of the injection pipe 57 is sealed. S5 Surface Pre-cooling: After the filling is completed, let it stand for 3 to 5 seconds for natural pre-cooling, so that a preliminary hardening layer with a thickness of 0.1 to 0.3 mm is formed on the outer surface of the antibacterial glass liquid, preventing the antibacterial glass liquid from being dispersed by the airflow during the subsequent blowing process; S6 Air Blowing and Shaping: Dry compressed air with a pressure of 0.2 to 0.4 MPa is introduced into the quick-release connector 51 and the connecting air passage 54 inside the core body tube 52 through the air passage interface at the upper end of the air connection pipe 34. The compressed air is sprayed out through the air outlets 55 evenly distributed on the side wall of the air blowing end 53, so that the antibacterial glass liquid is evenly attached to the inner wall of the molding cavity to form the preliminary shape of the container. S7 Cooling and solidification: Maintain compressed air pressure for 5 to 8 seconds, and at the same time accelerate the heat exchange between the mold and the antibacterial glass liquid through the cooling components 413 evenly arranged on the outside of the fixed mold component 41 and the moving mold component 44, so that the container as a whole is cooled and solidified to below 500°C, avoiding irregular shrinkage and deformation during the cooling process; S8 Step-by-Step Mold Opening: First, start the lifting drive screw 33 to drive the lifting sliding plate 32 to move upward, causing the air blowing molding component 50 to completely detach from the molding cavity; in the initial stage of mold opening, the elastic block 454 is still engaged in the engagement positioning groove 433, and the moving mold part 44 drives the container carrying middle mold 43 to move synchronously through the moving mold base 45. When the container carrying middle mold 43 moves to the preset position, the limiting positioning block 22 is engaged in the mold opening limiting slot 434 to rigidly limit the container carrying middle mold 43. The drive cylinder 61 continues to drive the moving mold part 44 to move, causing the elastic block 454 of elastic material to elastically contract and disengage from the engagement guide groove 432, completing the automatic separation of the container carrying middle mold 43 and the moving mold part 44; S9 Part Removal and Mold Change: Remove the container carrier mold 43, which carries the formed container, from the mounting base plate 21 as a whole and transfer it to the subsequent trimming and annealing processes; replace the new container carrier mold 43 and complete the rapid positioning through the limit positioning block 22 and positioning guide 23, and repeat steps S2 to S8 for continuous production.
