Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding machine for cosmetic bottle boxes. Background Technology
[0002] Cosmetic bottle boxes typically refer to containers or outer boxes used for packaging cosmetics. These packages not only need to protect the cosmetics inside from external environmental influences (such as light, air, and moisture), but also need to meet aesthetic and brand promotion requirements. Cosmetic bottle boxes can be manufactured using various processes, among which injection molding is a common production process, especially suitable for cosmetic bottles and boxes made of plastic. Plastic injection molding is a process of using molds to shape thermoplastic or thermosetting plastics into specific shapes. For the production of cosmetic bottle boxes (which may refer to cosmetic cases, the outer shell of cosmetic bottles, or matching small boxes, etc.), the selection and configuration of injection molding machines will be determined based on factors such as specific product design, material requirements, and production efficiency.
[0003] In the current injection molding process for cosmetic bottle boxes, raw materials are poured into a hopper, which then discharges them into the injection molding head. However, the raw materials accumulate in the hopper, causing them to stagnate during feeding and resulting in slow material discharge, which affects injection molding production. This requires manual clearing of the raw materials in the hopper. Furthermore, the existing injection molding head only has heat dissipation holes on the outside for cooling, resulting in slow heat dissipation. If the injection molding head temperature is too high, the raw materials may decompose, leading to product quality problems or the generation of harmful gases. Therefore, cooling the injection molding head can prevent this from happening. Utility Model Content

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0024] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments. Example
[0025] like Figures 1-6As shown, a cosmetic bottle box injection molding machine includes: an injection molding machine body 1, an injection molding head 101 installed at the outer end of the injection molding machine body 1, a feeding hopper 102 installed at the top of the injection molding head 101, a support base 2 installed at the bottom of the injection molding machine body 1, an anti-blocking component disposed inside the feeding hopper 102, the anti-blocking component including: a fixing block 3, an L-shaped support frame 301, a clearing motor 302, a motor shaft 303, a stirring rod 304 and a movable hole 305, and a heat dissipation component disposed outside the injection molding head 101, the heat dissipation component including: a heat exhaust hole 4, a heat dissipation shell 401, heat dissipation fins 402, a heat exhaust fan 403 and a protective net 404.
[0026] A fixing block 3 is installed between the feeding hopper 102 and the injection molding machine body 1. An L-shaped support frame 301 is installed on the top of the fixing block 3. A dredging motor 302 is installed on the top of the L-shaped support frame 301. A motor shaft 303 is installed at the bottom output end of the dredging motor 302. Multiple stirring rods 304 are installed on both sides of the outer end of the motor shaft 303. An movable hole 305 is opened on the top of the L-shaped support frame 301. The motor shaft 303 passes through the movable hole 305 and extends into the inside of the feeding hopper 102.
[0027] When the injection molding machine body 1 is used to produce cosmetic bottle boxes, the raw material is poured into the feeding hopper 102. Since the feeding hopper 102 is connected to the injection molding head 101, the raw material inside the feeding hopper 102 can be discharged into the injection molding head 101. The heating block inside the injection molding head 101 works to heat the plastic granules entering the injection molding head 101 until they are completely melted. The auger driven by the drive motor at the outer end of the injection molding head 101 can smoothly transport the material to the mold inside the injection molding machine body 1, and the cosmetic bottle box is formed by the mold. For those skilled in the art, the conventional working principle of the injection molding machine body 1 is common knowledge, so it will not be described in detail.
[0028] When the raw material accumulates inside the feeding hopper 102 and becomes difficult to flow, the user can control the unblocking motor 302 to start working through the control box on the outside of the injection molding machine body 1. The unblocking motor 302 drives the motor shaft 303 to drive multiple stirring rods 304 to rotate inside the feeding hopper 102, stirring and unblocking the raw material inside the feeding hopper 102, preventing blockage inside the feeding hopper 102, and ensuring that the raw material can be smoothly fed into the injection molding head 101 for processing, avoiding affecting the injection molding production of cosmetic bottles and boxes.
[0029] The multiple agitator rods 304 have a gradually decreasing length from top to bottom. The outer surface of each rod is coated with a wear-resistant coating. When the motor shaft 303 extends into the feeding hopper 102, the multiple agitator rods 304 on both sides of the outer end of the motor shaft 303 are also located inside the feeding hopper 102. The feeding hopper 102 has a conical structure, and the gradually decreasing length of the agitator rods 304 perfectly matches the conical structure of the feeding hopper 102, facilitating the clearing and preventing blockage of the raw materials inside the feeding hopper 102. Furthermore, the wear-resistant coating on the outer surface of the agitator rods 304 is a silicon carbide wear-resistant coating, which increases the wear resistance of the agitator rods 304, preventing easy damage during use and extending their service life.
[0030] The bottom outer side of the feeding hopper 102 is equipped with a transparent observation window 5, and an outer protective frame 501 is installed on the outer side of the observation window 5. During the use of the feeding hopper 102, the raw materials inside the feeding hopper 102 can be observed through the observation window 5 to see if the raw materials inside the feeding hopper 102 have been discharged, so as to add raw materials into the feeding hopper 102 in a timely manner, ensuring that the raw materials can continuously enter the injection head 101 for processing and be transported to the injection molding machine body 1 for molding.
[0031] The injection molding machine body 1 is equipped with a matching door 6 on its outer side. The top outer side of the injection molding machine body 1 is equipped with a slide rail 601. The top inner side of the door 6 is equipped with a slide groove that is slidably connected to the slide rail 601. A handle 602 is installed on one side of the outer end of the door 6. Limit heads 7 are installed on both sides of the bottom of the outer end of the injection molding machine body 1. A slide rod 701 is installed between the two limit heads 7. A slide hole 702 that is slidably connected to the slide rod 701 is opened inside the bottom end of the door 6.
[0032] After the molten raw material is processed into a cosmetic box product through a mold inside the injection molding machine body 1, the door 6 is pulled by grasping the handle 602. The slide groove at the top of the door 6 slides at the slide rail 601, and the slide hole 702 at the bottom slides at the slide rod 701, which makes it easy to open the door 6 and take out the molded cosmetic box product. The limit head 7 can restrict the sliding of the door 6 and prevent the door 6 from sliding out of the injection molding machine body 1.
[0033] The injection molding head 101 has several heat dissipation holes 4 on both sides of its outer end. A heat dissipation shell 401 is installed on the outside of the injection molding head 101. Heat dissipation fins 402 are installed at the top and bottom of the injection molding head 101. The heat dissipation fins 402 are located inside the heat dissipation shell 401. Heat dissipation fans 403 are installed at the top and bottom of the heat dissipation shell 401 at positions relative to the heat dissipation fins 402. Protective nets 404 are installed on the outside of the heat dissipation fans 403.
[0034] During use, the injection molding head 101 heats up due to the heating and melting of the raw material inside. The heat can be dissipated from the injection molding head 101 through the heat dissipation hole 4, and the heat dissipation speed can be accelerated by the heat dissipation fins 402. The heat dissipation fins 402 are all aligned with the heat dissipation fan 403. The user can start the heat dissipation fan 403 to absorb the heat conducted by the heat dissipation fins 402 and dissipate it to the outside of the heat dissipation shell 401, thereby accelerating the heat dissipation and cooling speed of the injection molding head 101, achieving cooling of the injection molding head 101, and reducing quality problems during the production of cosmetic boxes.
[0035] During the use of the exhaust fan 403, the protective net 404 can prevent impurities or dust from entering the exhaust fan 403 and avoid damage to the exhaust fan 403.
[0036] A control box is installed on the outside of the injection molding machine body 1. The drive motor, injection molding machine head 101, unblocking motor 302, and exhaust fan 403 at the outer end of the injection molding head 101 are electrically connected to the control box. The control box is equipped with start and stop buttons for the drive motor, injection molding head 101, unblocking motor 302, and exhaust fan 403 at the outer end of the injection molding head 101. Users can start or stop the drive motor, injection molding head 101, unblocking motor 302, and exhaust fan 403 at the outer end of the injection molding head 101 according to actual usage needs. The power of this injection molding machine is provided by an external power source.
[0037] Working principle:
[0038] When the injection molding machine body 1 is used to produce cosmetic bottle boxes, the raw material is poured into the feeding hopper 102. Since the feeding hopper 102 is connected to the injection molding head 101, the raw material inside the feeding hopper 102 can be discharged into the injection molding head 101. The heating block inside the injection molding head 101 works to heat the plastic granules entering the injection molding head 101 until they are completely melted. The auger driven by the drive motor at the outer end of the injection molding head 101 can smoothly transport the material into the mold inside the injection molding machine body 1. The mold forms the finished product. When the raw material of the cosmetic bottle box accumulates inside the feeding hopper 102 and becomes difficult to flow, the user can control the unblocking motor 302 to start working through the control box on the outside of the injection molding machine body 1. The unblocking motor 302 drives the motor shaft 303 to drive multiple stirring rods 304 to rotate inside the feeding hopper 102, stirring and unblocking the raw material inside the feeding hopper 102, preventing blockage inside the feeding hopper 102, ensuring that the raw material can be smoothly fed into the injection molding head 101 for processing, and avoiding affecting the injection molding production of cosmetic bottle boxes.
[0039] During use, the injection molding head 101 heats up due to the heating and melting of the raw material inside. The heat can be dissipated from the injection molding head 101 through the heat dissipation hole 4, and the heat dissipation speed can be accelerated by the heat dissipation fins 402. The heat dissipation fins 402 are all aligned with the heat dissipation fan 403. The user can start the heat dissipation fan 403 to absorb the heat conducted by the heat dissipation fins 402 and dissipate it to the outside of the heat dissipation shell 401, thereby accelerating the heat dissipation and cooling speed of the injection molding head 101, achieving cooling of the injection molding head 101, and reducing quality problems during the production of cosmetic boxes.
[0040] After the molten raw material is processed into a cosmetic box product through a mold inside the injection molding machine body 1, the door 6 is pulled by grasping the handle 602. The slide groove at the top of the door 6 slides at the slide rail 601, and the slide hole 702 at the bottom slides at the slide rod 701, which makes it easy to open the door 6 and take out the molded cosmetic box product. The limit head 7 can restrict the sliding of the door 6 and prevent the door 6 from sliding out of the injection molding machine body 1.
