Description

Technical Field

[0001] This utility model relates to the field of blow molding machine technology, and in particular to a blow molding machine for producing glass bottles for cosmetics. Background Technology

[0002] A blow molding machine is a machine that blows bottles. In its simplest sense, it is a machine that can blow plastic granules (softened into liquid) or pre-made bottle preforms into bottles through certain processes. Blow molding machines are convenient, fast, and have a large production capacity. After their emergence, they replaced most manual blow molding and were adopted by most beverage companies.

[0003] Traditional blow molding machines for producing glass bottles for cosmetics mainly consist of raw material plasticizing, preform forming, blow molding, cooling, and a control system. During operation, the plastic raw material is heated and melted by a screw extruder and then formed into a preform through injection molding or extrusion. The preform is then fed into a heating furnace for secondary heating and softening, and then placed in a mold. High-pressure air is injected through the blow molding system, causing the preform to expand and fit into the mold cavity. The cooling system cools and shapes the bottle through the circulation of cooling water inside the mold and external air cooling. The control system regulates parameters such as temperature and pressure.

[0004] However, traditional blow molding machines have two major problems: First, mold installation relies on bolt tightening, which requires time-consuming disassembly with tools such as wrenches, resulting in low mold change efficiency and complex operation, making it difficult to meet the production needs of cosmetic packaging with multiple specifications and small batches; Second, the temperature of the bottle body is high after molding, and direct handling by personnel can easily cause burns. Moreover, due to the lack of a cooling system, the high temperature not only poses a safety hazard, but also accelerates the aging of equipment parts, increasing the risk of equipment wear and tear and maintenance costs.

[0005] Therefore, a blow molding machine for producing glass bottles for cosmetics is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a blow molding machine for the production of glass bottles for cosmetics, aiming to improve the existing technology's inability to meet the production needs of cosmetic packaging in multiple specifications and small batches, and the high temperature after the bottle is formed, which makes it easy for manual handling to cause burns.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a blow molding machine for producing cosmetic glass bottles, comprising a worktable, a fixed frame fixedly connected to the upper side of the worktable, cylinders fixedly installed on both sides inside the fixed frame, a mounting base fixedly connected to the telescopic end of the cylinders, a mold arranged inside the mounting base, a blow molding head arranged on the upper side of the mold, an installation assembly arranged between the mounting base and the mold, an electric slide rail fixedly installed at the inner bottom of the worktable, an electric slider slidably connected to the upper side of the electric slide rail, an electric push rod fixedly connected to the upper side of the electric slider, a flexible support frame fixedly connected to the telescopic end of the electric push rod, a fixed frame fixedly connected to the outer side of the worktable, a cooling box fixedly installed inside the fixed frame, a liquid inlet pipe fixedly connected to the upper side of the cooling box, a cooling fan fixedly installed on the right side of the cooling box, and a dustproof net arranged on the right side of the cooling fan.

[0008] Furthermore, the mounting assembly includes a T-shaped block, which is fixedly connected inside the mounting base. The mounting base has a T-shaped groove inside, a limiting plate is hinged to the right side of the mounting base, a positioning pin is provided inside the limiting plate, and a positioning hole is provided on the upper surface of the mounting base.

[0009] Furthermore, a hydraulic cylinder is fixedly installed on the upper side of the fixing frame, and the telescopic end of the hydraulic cylinder is fixedly connected to the upper side of the blow molding head.

[0010] Furthermore, the T-block is slidably connected inside the T-slot, and the locating pin is slidably connected inside the locating hole.

[0011] Furthermore, the flexible support frame is slidably connected inside the worktable.

[0012] Furthermore, the mold is slidably connected to the lower side of the blow molding head.

[0013] Furthermore, a door is hinged to the front side of the workbench.

[0014] Furthermore, a controller is fixedly installed on the right side of the mounting bracket, and the controller is electrically connected to the cylinder, electric slide rail, electric push rod and cooling fan.

[0015] This utility model has the following beneficial effects:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-2This utility model provides an embodiment of a blow molding machine for producing cosmetic glass bottles, comprising a workbench 1, a fixed frame 2 fixedly connected to the upper side of the workbench 1, cylinders 3 fixedly installed on both sides inside the fixed frame 2, a mounting base 4 fixedly connected to the telescopic end of the cylinders 3, a mold 6 provided inside the mounting base 4, the mold 6 slidably connected to the lower side of the blow molding head 17, the blow molding head 17 provided above the mold 6, and a hydraulic cylinder 18 fixedly installed on the upper side of the fixed frame 2, the telescopic end of the hydraulic cylinder 18 being connected to the blow molding head 17. The upper side of the head 17 is fixedly connected, and an installation component 5 is provided between the mounting base 4 and the mold 6. The installation component 5 includes a T-block 52, which is fixedly connected inside the mounting base 4. A T-slot 51 is provided inside the mounting base 4. A limit plate 53 is hinged to the right side of the mounting base 4. A positioning pin 54 is provided inside the limit plate 53. A positioning hole 55 is provided on the upper surface of the mounting base 4. The T-block 52 is slidably connected inside the T-slot 51, and the positioning pin 54 is slidably connected inside the positioning hole 55.

[0026] Specifically, firstly, based on the specifications of the glass bottle to be blown, a suitable mold 6 is selected. The T-shaped block 52 on the back of the mold 6 is smoothly slid into the T-shaped groove 51 inside the mounting base 4 to complete the lateral positioning. Then, the limiting plate 53 is flipped over to cover the side of the mold 6, and the positioning pin 54 is precisely inserted into the positioning hole 55. The mechanical locking structure ensures that the mold 6 is stable and without displacement during the high-pressure blow molding process, achieving the effect of quick assembly and disassembly of the mold 6 and high-precision positioning. Compared with the traditional bolt fastening method, the mold change time is shortened, effectively improving the equipment's adaptability to multi-specification production. After installation, the controller 16 is started, and the telescopic end of the cylinder 3 pushes the mounting bases 4 on both sides to move synchronously, so that the mold 6 closes and clamps the bottle preform. At the same time, the hydraulic cylinder 18 drives the blow molding head 17 to descend vertically and tightly connect with the bottle mouth. Then, the high-pressure airflow is injected into the bottle preform through the blow molding head 17, causing it to expand and fit into the mold cavity to complete the molding.

[0027] Reference Figures 3-4 An electric slide rail 7 is fixedly installed on the inner bottom of the workbench 1. An electric slider 8 is slidably connected to the upper side of the electric slide rail 7. An electric push rod 9 is fixedly connected to the upper side of the electric slider 8. A flexible support frame 10 is fixedly connected to the telescopic end of the electric push rod 9. The flexible support frame 10 is slidably connected inside the workbench 1. A fixed frame 11 is fixedly connected to the outer side of the workbench 1. A cooling box 14 is fixedly installed inside the fixed frame 11. An inlet pipe 15 is fixedly connected to the upper side of the cooling box 14. A cooling fan 13 is fixedly installed on the right side of the cooling box 14. A dustproof net 12 is provided on the right side of the cooling fan 13. A door 19 is hinged to the front side of the workbench 1. A controller 16 is fixedly installed on the right side of the fixed frame 2. The controller 16 is electrically connected to the cylinder 3, the electric slide rail 7, the electric push rod 9 and the cooling fan 13.

[0028] Specifically, after the molding process is completed, the electric slide rail 7 drives the electric slider 8 to move laterally, conveying the flexible support frame 10 to a designated position below the mold 6. The electric push rod 9 adjusts the support frame to a suitable height according to the bottle height. At this time, the cylinder 3 retracts, releasing the mold 6. The molded mold 6, along with the glass bottle, falls naturally into the flexible support frame 10, achieving flexible support of the bottle. Compared with the traditional direct drop method, this avoids surface scratches caused by collisions and prevents damage to the bottle from rigid collisions. After the support frame supports the mold 6, the electric push rod 9 retracts, driving the components to reset. When the cooling process is started, the cooling tank 14 circulates coolant through the liquid inlet pipe 15 to continuously cool the mold 6; the cooling fan 13 operates synchronously, and the airflow is filtered through the dust filter 12 before being discharged from the equipment, maintaining the efficient operation of the cooling system. Once the mold 6 has cooled to the required level, the operator opens the door 19 on the front side of the workbench 1, and the electric slider 8 moves out of the equipment along the slide rail. The operator can then safely remove the finished glass bottle. The entire process is highly automated, avoiding manual contact with high-temperature parts, eliminating the risk of burns, and improving bottle removal efficiency while reducing the intensity of manual operation.

[0029] Working principle: When using this device, first, according to the required size of the blown bottle, slide the T-shaped block 52 of the appropriate mold 6 along the T-shaped groove 51 and insert it. Then, flip the limiting plate 53 and insert the positioning pin 54 into the positioning hole 55 to achieve mechanical locking. Subsequently, the cylinder 3 pushes the molds 6 on both sides to close and clamp the bottle preform. The hydraulic cylinder 18 drives the blow molding head 17 to descend and connect with the bottle mouth. High-pressure airflow is injected to make the bottle preform expand and form.

[0030] After molding, the electric slide rail 7 drives the electric slider 8 to move the flexible support frame 10 laterally to below the mold 6. The electric push rod 9 adjusts its height to fit the preform. The cylinder 3 is released, and the molded mold 6 falls into the flexible support frame 10. The electric push rod 9 is then activated to retract the mold. The cooling box 14 injects coolant through the liquid inlet pipe 15. At the same time, the cooling fan 13 is activated and the dust is filtered through the dustproof net 12 to maintain the heat dissipation efficiency and cool the mold 6. After cooling is completed, the door 19 is opened, and the electric slider 8 moves the flexible support frame 10 out for collection by the staff.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
